Chapter 10: From the Periphery to the Core of Decision Making – Options for Action

Main messages

We appear to be living in an era in which the severity of environmental problems is increasing faster than our policy responses. To avoid the threat of catastrophic consequences in the future, we need new policy approaches to change the direction and magnitude of drivers of environmental change and shift environmental policy making to the core of decision making. The main policy conclusions and messages of this chapter are:

Environmental problems can be mapped along a continuum from those where “proven” solutions are available to those where both the understanding of the problem and its solutions are still “emerging.” For problems with proven solutions, the cause-and-effect relationships are well known, the scale tends to be local or national, impacts are highly visible and acute, and victims are easily identified. However, the emerging problems (also referred to as “persistent” environmental problems) are rooted in structural causes. Many of the same causes of these environmental problems simultaneously underpin entrenched poverty and over-consumption. For these environmental problems, some of the basic science is known about cause-and-effect relationships, but often not enough to predict a point of no return. They often need global or regional responses. Examples include climate change, stratospheric ozone depletion, persistent organic pollutants and heavy metals, tropospheric ozone, acid rain, large-scale deterioration of fisheries, extinction of species, and alien invasive species.

Environmental policy has been successful in solving many environmental issues, especially where marketable technical solutions are available. Such policy success, however, needs to be continually extended, adapted and re-assessed, particularly in parts of the developing world, where many of the environmental problems effectively addressed elsewhere seriously threaten the well-being of billions of people.

The range of policies (the toolbox) for dealing with environmental issues has, in the past 20 years, become more sophisticated and diversified. There are many promising examples showing how this powerful toolbox can be deployed effectively. For instance, many governments have used command-and-control and market-based instruments to achieve environmental goals, community participation techniques to help manage natural resources, and technological advances to implement policy more effectively. Other actors, in the private sector and civil society, have formed innovative voluntary partnerships to contribute to achieving environmental goals.

Success in addressing environmental problems with proven solutions, however, will not solve “the urgent but complex problems bearing on our very survival” that the Brundtland Commission articulated.There is a set of environmental problems for which existing measures and institutional arrangements have systematically demonstrated inadequacies. Achieving significant improvements for a long period on these problems, which emerge from the complex interaction of biological, physical and social systems involving multiple economic sectors and broad segments of society, has been impossible and, for some, the damage may be irreversible.

The search for effective policy responses to these emerging environmental problems has recently focused on options to transform their drivers. Although environmental policy responses have typically focused primarily on reducing pressures, achieving particular environmental states or coping with impacts, policy debates are increasingly concerned with how to address drivers, such as population and economic growth, resource consumption, globalization and social values.

Fortunately, the range of policy options to influence economic drivers is more advanced than at the time of the Brundtland Commission report, Our Common Future. These include the use of green taxes, creation of markets for ecosystem services and use of environmental accounting. The analytical foundation for such approaches has been refined, and governments are gaining experience in implementing them, although typically only at relatively small scales.

An organizational focus at all levels on these emerging environmental problems requires the shifting of the environment from the periphery to the core of decision making. The current role that the environment plays in governmental and intergovernmental organizations, and in the private sector could be made more central through structural changes, mainstreaming of environmental concerns into sectoral plans and a more holistic approach to development planning and implementation.

Regular monitoring of policy effectiveness is urgently needed to better understand strengths and weaknesses, and facilitate adaptive management. This infrastructure has not appreciably expanded in the past 20 years, even though policy goals have broadened considerably. Welfare cannot be measured by income only, and aggregate indicators have to take into account the use of natural capital as well. Of particular urgency is an improved scientific understanding of the potential turning points, beyond which reversibility is not assured.

For many problems, the benefits from early and ambitious action outweigh their costs. Both ex-post evaluations of the costs of ignoring warnings as well as the scenarios on the costs of global environmental change show that determined action now is cheaper than waiting for better solutions to emerge. In particular for climate change, our knowledge on the costs of inaction shows a worrying picture even while immediate measures are affordable.

Political decisions need support and legitimacy to be implemented. The knowledge basis for the environmental issues has expanded enormously during the last 20 years. Similarly, the range of options to influence social attitudes, values and knowledge has also expanded. Better environmental education programs and awareness campaigns, and much more attention to involve various stakeholders will make environmental policies better rooted. An educated and more involved population will be more effective in addressing failures of government and holding institutions to account.

The new environmental policy agenda for the next 20 years and beyond has two tracks:

• expanding and adapting proven policy approaches to the more conventional environmental problems, especially in lagging countries and regions; and
  

• urgently finding workable solutions for the emerging environmental problems before they reach irreversible turning points.
  

Policy-makers now have access to a wide range of innovative approaches to deal with different types of environmental problems. There is an urgent need to make choices that prioritize sustainable development, and to proceed with global, regional, national and local action.

It is imperative for policy-makers to have the tools that help reduce the political risks of making the right decisions for the environment. The political fallout for making a rushed decision that is subsequently proven wrong can be politically damaging, especially if powerful political supporters are adversely affected.

Introduction

“Since the answers to fundamental and serious
concerns are not at hand, there is no
alternative but to keep on trying to find them.”
Our Common Future

Fig 10.1 Two tracks to address environmental problems with proven and emerging solutions.

In the two decades since the World Commission on Environment and Development (Brundtland Commission) described a set of “urgent but complex problems bearing on our very survival” ^[2], the global concern over environment and development issues has expanded. However, clear solutions and institutional mechanisms remain poorly defined. The problems identified by the commission have grown more severe, and new problems that were not foreseen have arisen. The main environmental problems described in previous chapters of this report can be categorized along a continuum – from those where “proven” solutions are available, to those where both the understanding of the problem and solutions are still “emerging” (see Figure 10.1).

Problems at the latter end of the continuum share a number of characteristics that make them hard to manage, including complex interactions across global, regional and local scales, long-term dynamics, and multiple stressors and stakeholders (see Chapter 1). Many of these hard to manage problems can be termed “persistent” environmental problems^[3]. Unfortunately, policy making and institutional reforms remain anchored in the less complex, more manageable environmental challenges of the 1970s, and have not kept pace with the emergence of these persistent environmental problems.

An inventory of environmental policy goals and targets, a review of experience in managing cross-cutting issues, an assessment of the adequacy of multilateral environmental agreements (MEAs), along with the scenario policy analyzes in Chapter 9, underpin this review. Evidence shows that there is an urgent need to address the types of environmental problems that may have irreversible consequences, which may make local, regional, or even global environments progressively uninhabitable.

The future policy options point to the need for a two-track approach:

• expanding and adapting proven policy approaches to the more conventional environmental problems, especially in lagging countries and regions; and

• urgently finding workable solutions for the emerging environmental problems before they reach irreversible turning points.

Over time, both tracks are expected to merge into one, as the environmental policy agenda is progressively moved from the periphery to the core of economic and social development decision making.

For the first track, management and institutional approaches can learn from successful application of environmental policies in other parts of the world. The second track involves dealing with emerging environmental problems, and creating new institutional arrangements based on adaptive management, finding innovative financing mechanisms and improving monitoring, evaluation and social learning. Both tracks, however, need greater focus to address underlying societal and cultural values, increased education, empowerment of citizens and decentralized governance structures.

Current Environmental Policy Responses

Management of environmental problems

Fig 10.2 Mapping environmental problems according to management and reversibility. (Based on Chapters 2–-5)

Environmental problems appear as impacts on nature and human well-being, through the air and atmosphere, in fresh and marine water, and on land. Most aspects of these environmental problems are described in the previous chapters. Eighteen of the key environmental issues discussed in Chapters 2–5 have been organized to illustrate the difficulty of management, and the extent to which the problems can be seen as having reversible or irreversible consequences, making local, regional or even global environments progressively uninhabitable (see Figure 10.2). While it is recognized that other dimensions could be used, GEO-4 has organized the environmental problems in two main clusters along a continuum.

Problems with proven solutions

The cause-and-effect relationships are well known, single sources generally can be identified, the potential victims are often close to those sources and the scale is local or national. Good examples of success stories for solving these environmental problems are available for microbial contamination, harmful local algal blooms, emissions of sulfur, nitrogen oxides, particulate matter, oil spills, local land degradation, localized habitat destruction, fragmentation of land, and overexploitation of freshwater resources.

Problems with emerging solutions

Some of the basic science about cause-and-effect relationships is known, but often not enough to predict when a turning point or a point of no return will be reached, or exactly how human well-being will be affected. The sources of the problem are quite diffuse and often multisectoral, potential victims are often quite remote from the sources, extremely complex multi-scale ecological processes may be involved, there may be a long time between causes and impacts, and there is a need to implement measures on a very large scale (usually global or regional). Examples include global climate change, stratospheric ozone depletion, persistent organic pollutants and heavy metals, extinction of species, ocean acidification, and introduction of invasive alien species.

The environmental problems at the “emerging solutions” end of the continuum have implications for development, in two fundamental ways:

• Environmental resources and change create direct opportunities and threats for development^[4]. Natural capital frequently constitutes economically important assets, the management of which has a strong impact on economic growth^[5]. Poor countries generally have a higher percentage of their total assets comprised of environmental resources than produced capital^[6]. Environmental resources frequently affect risk exposures, by mediating or altering natural hazard vulnerability. They frequently play an important role in empowerment of vulnerable social groups, including women; marginalized ethnic, linguistic or regional populations; and the extremely poor. Environmental resources can also play a strong role in shaping the long-term viability of economic development strategies.

• The diagnosis of the causes of persistent environmental problems shares much in common with similar diagnoses of persistent development problems. In particular, the large gap between proven governance mechanisms and the magnitude and complexity of environmental problems is similarly found in areas where development is lagging.
  

Therefore, there are strong reasons for coordinating the environment and development agendas. This message is implicit behind the overarching design of major international processes, such as Agenda 21 and the Johannesburg Plan of Implementation, but a major gap remains between both the environment and development agendas^[7].

The cluster of large-scale, persistent environmental problems has more complex interlinkages, and it is more difficult to get concerted effort at multiple scales to solve the intertwined problems (see Chapter 8). As the Brundtland Commission stated, they are often part of “the downward spiral of linked ecological and economic decline in which many of the poorest nations are trapped”^[8].

Success stories for solving these kinds of environmental problems are much less common than for the environmental issues identified in the 1970s. In addition, left unattended or uncontrolled, many issues in the first cluster can coalesce and contribute to the persistent problems. For example, expanding local land degradation (see Chapter 3) may result in dust and sandstorms at the regional scale, contributing to atmospheric brown clouds that contribute to global dimming (reduced solar radiation reaching the ground) and impacts on regional monsoons (see Chapter 2).

Elevating environment on the policy agenda

At all points on the continuum, there are significant challenges involved in raising the profile of environmental issues in public policy, but the opportunities are also numerous. Elevating the profile of environmental issues in public policy might involve the following actions.

Raising the profile of the environmental agenda

Although sustainable development has gained general political support, environment remains low on the policy agenda in most day-to-day politics. Poverty reduction, economic growth, security, education and health are clearly the highest priority policy items. Proving that the environment underpins and contributes significantly to all of these high priority issues can raise its political visibility, leading to more political support^[9].

Strengthening integration

Traditionally, environmental policy-makers have not focused on establishing linkages with other important policy agendas, such as poverty reduction, health and security in developing countries, or with economic sectors in developed countries. Phasing out environmentally damaging subsidies may, for instance, release funds for more targeted support for the poor, as well as improve the environment. Integrating environmental policy into other policy areas involves a continuous, adaptive process. End-of-pipe pollution controls in the 1970s led to cleaner production processes in the 1980s and zero-waste factories in the 1990s. Modern environmental policy and legislation needs to follow a similar, stepwise evolutionary path to finding and applying solutions for persistent environmental problems^[10].

Setting clear goals and targets, and strengthening monitoring

Political commitments to specific goals and targets are essential to effectively address environmental issues. Developments in this area are often only visible over the medium- to long-term, and tend to escape day-to-day political attention. Therefore, scientific research and monitoring, and information systems need to be maintained at adequate levels, and progress against benchmarks regularly reviewed by an independent body^[11]. The lack of quantifiable targets for Millennium Development Goal (MDG) 7 on environmental sustainability has been one factor in its relatively low profile on the global agenda^[12]. The need to revisit time-bound targets under MDG 7 would be strategic in strengthening monitoring and accountability.

Reinforcing stakeholder involvement

A participatory approach facilitates collaborative efforts among various stakeholders, engenders a sense of ownership and makes new initiatives more sustainable. An informed population is also more effective in addressing failures of governments, enhancing transparency and holding institutions accountable. Although stakeholder participation often requires additional upfront costs in terms of time and resources it has, particularly at the local level, proven to be a successful instrument and may ultimately result in reduced costs^[13]. However, in many countries and at the international level, the formal right to take part in the decision making process often remains restricted.

Building on small-scale successes

For internationally funded projects and initiatives, the scale of operation is proportional to funds available. Therefore, many environmental initiatives have not been scaled up to the extent where real environmental change may take place^[14]. Once the scale of an environmental problem goes beyond national borders, it is much harder to justify allocating national budgets or bilateral development assistance, creating potential free-rider problems.

Clarifying the role of government

Economic activity is interlinked to land, water, and the atmosphere and environmental policy making must, therefore, involve the integration of all these aspects. (Credit: Ngoma Photos)

Frequently, environmental ministries are seen as acting more like facilitators than implementers: steering not rowing. Priority could be given to the development of more effective policies and policy coherence. Environmental ministries could concentrate more on translating environmental aims and the results of research and monitoring into long-term objectives, priorities, basic legislation and mandatory limits. They should also be charged with reviewing the environmental results for each sector. In turn, sectoral departments need to build the necessary capacity to interpret and internalize environmental priorities into their policies, and take greater responsibility for implementing environmental activities. In some countries, restructuring has already taken place, and environmental units can now be found in the sectoral ministries, although loyalty may remain with sectoral interests^[15].

Avoiding over-sophisticated legislation

In developed countries, incremental modifications of environmental regulations and lack of involvement of regulatory practitioners in this process make some legislation almost incomprehensible. Room for corruption has been enlarged, and an unnecessary burden has been imposed on industry. When these policy instruments are transferred to developing countries, which often have inadequate capacity to develop innovative, home-grown policies, the excessive level of sophistication makes them impossible to implement. Much clearer and more cost-effective regulations can be set up, drawing, whenever possible, upon capacities of other stakeholders^[16]. Ideally, investing in capacity building, and supporting inclusive national legislative development processes will prove more beneficial in the long run.

Tackling hard choices

Many situations exist today where “win-win” solutions are impossible. Objective assessments, backed by freely accessible, high-quality information and public consultation, are needed to weigh trade-offs between potential alternatives. Economic valuation of non-market environmental goods-and-services, and consideration of potential social impacts need to be included in any objective evaluation of alternatives. Political leadership is essential. Delaying decisions may result in needless damage and death^[17], as well as possible irreversible change for which no trade-offs should be contemplated.

Critical policy gaps and implementation challenges

Successes tempered by policy gaps

The linear, single-source, single medium environmental problems that dominated the agenda at the 1972 Stockholm conference were, for the most part, subjected to increasingly effective management over the following two decades. Environmental ministries were created, national legislation governing air and water quality was implemented, and standards for exposure to toxic chemicals were adopted. Based on the analyzes in Chapters 2–8, it can be concluded that nearly all countries now have a set of policy instruments, if not an explicit environmental policy, which provides a platform for improved environmental management^[18]. There is also support for projects and innovative experiments to enhance the capacities of personnel and promote better environmental management in most developing countries.

Considerable effort has been invested in new approaches to environmental policy making^[19]. Although there were failures, and many good policies were not implemented, due to institutional constraints, progress has been sustained and significant in a large number of countries. In some urban areas, environmental quality is better today than in the mid-1980s. The main policy gap is in ensuring that policies and organizational arrangements that have worked in some areas are sustained and extended to all (especially developing) countries. While there is an unfinished agenda that affects the well-being of billions of people, the necessary resources and political will to provide the enabling environment are still too often neglected.

Complex problems remain a major policy challenge

By contrast, the complex, multi-source, persistent environmental problems highlighted by the Brundtland Commission, and those that have emerged since have not been effectively managed anywhere^[20]. There are no major issues raised in Our Common Future for which the foreseeable trends are favorable. Apart from the obvious need to mainstream these problems into national decision making processes, workable policies for dealing with issues that require fundamental transformations in modern societies have yet to emerge.

Despite positive trends observed in some countries, the global environment remains under severe threat, and important ecosystems and environmental functions may be approaching turning points, beyond which the consequences could be disastrous (as shown in earlier chapters of this report). Therefore, there is an urgent need to reinvigorate the environmental dimension of development, to set realistic goals and targets (see Box 10.1), and to ensure that environmental goals and requirements are integrated into mainstream public policy at global, regional and national levels.

Box 10.1 Overview of global policy targets[21]

Fig 10.3 An overview of global policy targets. As part of this assessment, policy targets associated with the high-priority global environmental problems analyzed in Chapters 2–5 were identified and characterized. Global targets were the primary focus, but sub-global targets that covered large numbers of countries were also analyzed. At the level of objectives, or general statements of principle, the global community has articulated clear objectives fairly consistently across all the high-priority problems. However, when it comes to targets, or specific, quantifiable, time-bound outcomes, the situation is more uneven. For the most challenging problems, characterized by many of the dimensions of persistence, targets are less common, whereas they are more prevalent among the problems characterized as having proven solutions available. In terms of water, for example, clear targets exist concerning access to piped water and basic sanitation, which are linked to the broader objective of reducing the most pressing aspects of poverty. By contrast, although the objective of integrated watershed management is almost equally widespread, targets concerning how to implement it are rarer. There are clear, widespread targets already embedded in decision making concerning urban air pollution, but this is not the case for indoor air pollution. The degree to which policy targets are supported by monitoring and evaluation procedures varies considerably. For ozone depletion, for example, there is a robust monitoring program that measures the atmospheric concentration of ozone-depleting substances, ozone layer thickness, and trends in production, consumption and emissions. By contrast, most of the biodiversity protection targets lack baseline benchmarks and the kind of regular monitoring that would permit tracking of trends. Most targets aim at improving generic capacities (including adoption of plans, creation of policy frameworks, conducting assessments and setting priorities), or at reducing pressures (lowering emissions, extraction or conversion). It is rarer to find targets that aim at reducing drivers or at achieving specific states. There are some biodiversity targets that target drivers, but none exist in other areas. Regional air pollution in Europe is the best-developed example of a targeting process that focuses on environmental states (in this case, levels of deposition relative to critical loads

Policy implications of scenarios

The scenarios highlighted in Chapter 9 illustrate the difficulties of responding to persistent environmental problems, and of rapidly changing directions. The environmental implications of the various scenarios illustrate the legacy of past decades and the level of effort required to reverse powerful trends. One of the major policy lessons from the scenarios is that there can be significant delays between changes in human behavior, including policy choices, and their environmental impacts, specifically:

• much of the environmental change that will occur over the next 50 years has already been set in motion by past and current actions^[22]; and
  

• many of the effects of environmentally relevant policies put into place over the next 50 years will not be apparent until long afterwards. The slow recovery of the ozone “hole” over Antarctica reflects this extended time dimension.
  

Enormous momentum is built into global economic systems, and many social forces are comfortable with (or profit from) the way the world is today. Combined with the lack of certainty over precisely when ecosystems may pass turning points, it is understandable that shifting trajectories in a deliberative, precautionary manner towards sustainability is so difficult. Nevertheless, the scenarios show:

• the very different outcomes if critical choices are not made in time; and
  

• the chance to avert global collapse exists if the right choices are made sooner rather than later.
  

A critical uncertainty in such scenarios is the ability to decouple pollution intensity from economic growth, and to shift towards service industries without lessening economic growth rates^[23].

Implementation challenges

Energy use and transport drive industrialization and urbanization. Many countries are now implementing policies to reduce inefficient use of energy, although change can be slow. (Credit: Ngoma Photos)

Implementation of good practices needs to be extended to countries that have been unable to keep pace, due to lack of capacity, inadequate finances, neglect or socio-political circumstances. Due to internal or international pressures, most countries have already adopted some policies to address the environmental issues with proven solutions. Implementation of these policies, however, remains relatively weak or non-existent in many developing countries. In some cases, it appears as if there is no real intention of implementing the policies, and governments are paying mere lip service to environmental management to pacify lobby groups or donors^[24].

In too many countries, environmental policy remains secondary to economic growth. Generally, macro-economic objectives and structural reform have been considered of higher priority than environmental quality. Nowhere has it been possible to integrate economic, ecological and social objectives consistently with a sustainable development model^[25]. Increasing global concerns, such as poverty and security, may even have moved environmental issues further towards the periphery of the political agenda^[26].

Elevating the agenda to tackle persistent environmental problems impinging on the structural core of societies poses implementation challenges that appear immense. While there are a few examples of countries that have made successful structural changes, worryingly, some countries are even backsliding in implementation of the conventional environmental agenda^[27].

Implementation of environmental policies requiring substantial societal or cultural changes, such as a culture of environmental protection, or structural realignment, will meet with fierce resistance from sectors affected and from some parts of the public. Therefore, governments tend to buy time or defer decisions when such “hard” structural changes in overall policies are required – often until they are inevitable^[28] . Hard choices are usually found where the environment and economy intersect or interact, posing structural issues that are difficult to address. The underlying drivers are more entrenched, cross-cutting social and economic problems, with the environment deeply embedded in them.

How important these changes are viewed and how serious governments are about making changes often depend on political ideology and value orientation. To implement such “hard” options, governments have limited opportunities to take a close look at precedents and experience before embarking on them. Often, consideration of social and political costs rather than the lack of funds hinder implementation^[29]. For example, removal of agricultural subsidies may have important environmental outcomes, but the political ramifications for making such changes are immense^[30]. Policies designed to yield reduced carbon emissions affect all sectors that use energy. Hence, sectoral agencies and affected stakeholders need to “buy into” environmental policies^[31].

The policies that are easiest to implement are those that do not involve redistribution of wealth or power– often termed “win-win” situations or “soft” options. Many soft options are already being used, such as generating public awareness, setting up organizations, formulating symbolic national legislation and signing weak international conventions. These often create the appearance of action without really tackling the core drivers of the persistent environmental problems.

Although some policy debates are beginning to draw attention to drivers as appropriate focal points for policy intervention^[32], their representation in global policy fora is in its infancy. In a systematic identification of all global policy targets pertaining to the high priority environmental problems identified in previous chapters, only 2 out of 325 distinct policy targets were aimed at drivers (see Box 10.1). The majority targeted pressures and improvements in coping capacity. The exceptions were targets aimed at promoting sustainable consumption of natural resources in the biodiversity and forest conservation policy areas.

Existing environmental organizations were often not designed to address complex cross-sectoral and transboundary policy implementation. Institutions have been unable to keep up with the fast pace at which economic growth is generating cumulative environmental degradation. As pointed out in the Brundtland Commission report, a holistic approach requires the integration of environmental concerns and measures across all sectors. As persistent environmental problems also affect countries across borders, and become sub-regional, regional or global problems as evident in Chapter 6, coordination and harmonization of implementation approaches raise new organizational challenges.

Improved knowledge management is critical for effective implementation of policies. Although some information regarding these persistent environmental issues is available, it is usually incomplete, and fails to bridge the gap between the technical measures observed and the human impacts that motivate policy-makers. They need clearly and easily understood frameworks, simple metrics and appropriate solutions to act upon. The scientific and academic community communicates the dimensions of such problems to policy-makers, using complex and incomplete measuring tools. While it is relatively easy to provide data on many of the most pressing economic and social outcomes, such as GDP and the Human Development Index, no equivalent concrete measuring tools have been broadly accepted in the environmental domain, although there are several competing options. One review found 23 alternative aggregate environmental indices^[33], and several more are under development.

Supporting valuation and measurement initiatives that build up a common platform of understanding of the impact of policies on sustainability, and clearly measure the environmental consequences of economic actions will assist sensible decision making. Consensus on valuation is important, because not all environmental goods-and-services can or should be monetized. Non-monetary valuation indicators that are commonly understood and agreed upon, in conjunction with financial and social indicators, can show the status and trends towards or away from sustainability.

The Future Policy Framework

A strategic approach

Environmental policy has been successful in solving a wide array of linear, single source, single medium or “conventional” environmental issues, especially where marketable technical solutions have been available, such as chemical replacements for ozone-depleting substances^[34]. However, persistent environmental problems, such as the rising concentrations of greenhouse gases, the loss of biodiversity, the accumulated contamination of soil and groundwater, and the cumulative effects of dangerous chemicals on human health, are issues where it has been impossible to achieve significant improvements for a long period of time and, for some, the damage may be irreversible^[35]. Failure to effectively address these persistent problems will undermine or negate all of the impressive achievements in finding solutions to the conventional problems.

Therefore, a two-track strategy is envisaged: adapting and expanding the reach of proven policies, and developing policies to deliver more deeply rooted and structural change at all levels.

centerTable 10.1 Classification of environmental policy instruments.

Expanding the reach of proven policies

Although a plethora of environmental challenges exist, there are also some effective policies available. Proven successes in environmental policy in other countries can be taken as an encouraging sign in those lagging countries beginning to face up to their own legacy of environmental degradation. Effective policies enhance a particular ecosystem service, and contribute to human well-being without significantly harming other ecosystem services or harming other social groups^[36]. Promising responses either do not have a long track record, and thus outcomes are not yet clear, or could become more effective if they were adequately modified. Problematic responses do not meet their goals or harm other ecosystem services or social groups.

Since 1987, the policy landscape has expanded enormously and direct and indirect environmental policies now impinge on virtually all areas of economic activity^[37]. One of many categorizations of environmental policies is provided in Table 10.1. The progressive evolution of policies from “command-and-control” to “creating markets” over the past two decades is illustrated in this classification.

The toolbox of policy instruments has been gradually expanded, with much more emphasis on economic instruments, information, communication, and voluntary approaches^[38]. These developments are partly related to the fact that the policy focus in the area of pollution control has shifted from the large single polluters (point sources) to more diffuse sources, that can be harder to control^[39]. However, direct regulation (also known as command-and-control) still plays a major role, and is likely to do so in the future^[40]. Some governments have begun to reform their environmental standards in favor of more ambitious, innovation-friendly systems. For example, the Japanese Top Runner Program on energy efficiency is receiving much attention. In this program, standards are adapted to the best available technologies, giving a continuous incentive to improve such standards.

To avoid market distortion between competing industries, or globalization-driven pollution havens, internationally agreed standards need to be developed and cautiously applied. (Credit: Ngoma Photos)

Governments will need to continue applying (or threatening to apply) “strong instruments,” such as command-and-control regulations, for effective policy implementation, even if the use of market forces and “soft instruments,” such as provision of information, play a more important part than before^[41]. An effective toolbox, therefore, has to include a wide variety of instruments, often used in concert, customized to the institutional, social and cultural milieu of the country or region concerned.

The challenge is to find the most efficient policy instrument or mix of instruments for a particular environmental problem in a particular geographic and cultural context. Increasingly, policy-makers are looking at complex models of social, economic and environmental systems to guide policy choices. However, these models themselves are inevitably partial representations of reality. For a number of environmental problems, direct command-and-control regulation will be an effective instrument, and this is therefore widely used today (see Box 10.2). In particular, the instrument is now used far more effectively to specify expected results rather than technical methods. Further, widely agreed technical standards, prescribed by law, may contribute to fair competition in the industry concerned, and also serve as an incentive for gradual technical development and innovation, improving environmental protection. In order to avoid market distortion between competing industries, or globalization-driven pollution havens, internationally agreed standards need to be developed and cautiously applied. While waiting for global action, groups of importers in some markets have already started to set voluntary standards for their own production and supply chains.

A wide range of success factors have been demonstrated as important in best practice policies. Some of the key factors include^[43]:

• solid research or science underpinning the policy;

• high level of political will, usually bipartisan and therefore sustained;
  

• multistakeholder involvement, often through formal or informal partnerships;

• willingness to engage in dialog with policy opponents;

• robust systems for mediating conflict;

• capable, trained staff engaged in implementation;

• prior systems of monitoring and policy revision agreed, including clauses that mandate periodic revision;

• legislative backing, combined with an active environmental judiciary;

• sustainable financing systems, ring-fenced from corruption;

• evaluation and assessment of policies independent from the rulemaking agent, for example, by advisory committees or public auditors;

• minimal delays between policy decisions and implementation; and

• coherence and lack of conflict throughout all government policies.

Finding new, transformative policies

The class of environmental problems still seeking solutions needs innovative policies to address survival or threshold issues. They will challenge existing societal structures, consumption and production patterns, economies, power relationships, and the distribution of wealth^[44]. There is an urgent need for a fundamental reorientation of public and private policies on environmental issues, and for transformative structural changes^[45].

Unfortunately, lack of political will has failed to make environment central to a government’s mission^[46]. Modern politics can be characterized as a continuous negotiation among politicians and special interests to get attention for their issues and interests (where the strongest interest often wins). This creates a chaotic situation that can easily focus on short-term, politically expedient gains, rather than long-term sustainable and equitable development^[47]. As long as politicians and citizens fail to recognize that human well-being depends on a healthy environment, and put issues other than environment among their top priorities, environmental policy-makers can only hope that other policies, such as economic, trade or development policies, will not make the environmental situation worse. Many of the persistent problems are slow to form, initially “invisible,” difficult to pin down precisely and inadequately weighted when trade-offs are being considered, failing to get the attention of politicians with short-term horizons^[48]. However, the political fallout for making a rushed decision that is subsequently proven wrong can be politically damaging, especially if powerful political supporters are adversely affected^[49]. It is, therefore, imperative for policy-makers to be provided with the tools that help reduce the political risks of making the right decisions for the environment.

For some persistent environmental problems, such as climate change and biodiversity loss, incentives for further environmental degradation are still being promoted, as these are primarily determined by other policy domains and their respective competing objectives^[50]. Despite best intentions, implementation of international environmental agreements by national governments to address such issues is failing, and there are few, if any, sanctions for such failure^[51].

Environmental policy failures are closely related to the challenge of a more encompassing integration of environmental concerns into other policy sectors^[52]. As environmental issues have become important in all sectors, there is a growing need to converge with economic development policies (see discussions of European efforts at cross-sectoral greening)^[53]. However, there is still no robust integrated policy assessment tool (notwithstanding good advances made in Europe) that ensures mainstreaming of environmental issues into all other sectoral policies^[54].

In part, environmental problems and mismanagement of natural resources result from not paying the full price for the use of ecosystem services^[55]. Governments adopt many different objectives that are often competing or even in conflict with each other, failing to recognize that they all depend on properly functioning ecosystem services. When economic development is given higher priority than environmental protection, policy failure is aggravated by the fact that environmental organizations are often weak, are seen as just another special interest and usually lose out in policy battles. Another complicating factor is the fact that throughout the developing world there is a widespread lack of implementation and enforcement of environmental legislation, due to insufficient administrative capacities^[56].

Ideally, sound science should underpin environmental policy choices. There is little doubt that the knowledge base on the key environmental issues has expanded enormously since 1987, but still too little is known about how close potential turning points are, or how to achieve long-term sustainable development. As noted in Our Common Future, “science gives us at least the potential to look deeper into and better understand natural systems”^[57]. The Brundtland Commission observed that scientists were the first to point out the growing risks from the ever-intensifying human activities, and they have continued to play that role in an increasingly coordinated manner.

The Intergovernmental Panel on Climate Change (IPCC), the Millennium Ecosystem Assessment, Global Environment Outlook, Global Marine Assessment, Global Forest Resources Assessment, Global Biodiversity Assessment, International Assessment of Agricultural Science and Technology for Development (IAASTD), and the Land Degradation Assessment in Drylands (LADA) are indicative of the shared concerns of the global science community, and a willingness to cooperate. These and other assessments have underpinned the MEAs, supported the global summits and conveyed important scientific information to the global community through the media and other means of dissemination. Scientists, statisticians, and people in other disciplines have become increasingly aware of the importance of communicating difficult issues in a form that decision-makers and the public can understand.

However, the almost daily diet of bad news emanating from these studies may have, paradoxically, conditioned the public and decision-makers to always expect predictions of disaster from scientists, despite the evidence that overall human well-being has progressively improved. The unceasing flow of scientific information has itself provided political cover for indecision and delay^[58]. When an isolated piece of good news on the science front, such as bringing back a species from the brink of extinction, is published, it is seized upon as evidence that the scientists are always exaggerating the dangers. The media, in their attempt at balanced reporting, can always find at least one scientist to contradict the general consensus of the majority of scientists, resulting in the common political view that the science is still uncertain, and, therefore, there is no need for precipitous action^[59].

The danger of this balanced, “no action needed yet” approach is that millions of lives might be needlessly lost, human health impaired, or species made extinct. The danger of delayed decisions has been clearly documented in the case of radiation, asbestos, chlorofluorocarbons, and other environmental and human health issues. Despite early warnings from scientists on these issues, it was decades before action was ultimately taken^[60]. Similar delays are being experienced in relation to climate change and biodiversity loss. The high degree of difficulty in finding innovative policy solutions for these persistent problems can be explained by several factors. The use of natural resources and the release of emissions to the environment are often determined by the logic of industrial production systems and their associated technologies. Hence, sustainable solutions require fundamental changes in industry structure, technologies and input factors for the sectors involved, such as mining, energy, transport, construction and agriculture. The government departments responsible for these sectors see their main duty as providing and securing the environment as a cheap (often free) input for production for their private (or public) sector clients. Such structural problems cannot be solved by environmental policy alone, but, instead, they need coordinated action by different parts of the policy making and implementation process of governments^[61].

International solutions are even more difficult to achieve, however, due to the relatively weak organizational framework and the many veto points that allow interest groups to stop ambitious policies^[62]. Even where MEAs have been ratified by national governments, effective implementation is hindered by financial and technical capacity constraints, onerous reporting procedures, non-cooperation of non-state actors and attention to other pressing issues^[63].

Effective policy instruments are those that provide long-term signals and incentives on a predictable basis. This is vitally important to the business sector, but also to consumers and households. Publishing long-term plans for how regulations will be tightened is one way of easing changes. To be socially acceptable, redistributive instruments, such as regulatory constraints and environmentally related taxes, and other economic instruments also need to be seen as fair and equitable.

Promising transformative policy options

There are a few promising policy options that demonstrate the power of innovative policies to contribute to the structural changes needed to solve persistent environmental problems. These need to be carefully monitored, and lessons learned disseminated widely and quickly, so that successful policies can be added to the toolbox, always bearing in mind the need for local adaptation and social learning.

Green taxes

A small part of increased tax revenue can be designated for increased energy conservation and energy efficiency measures. Taxing environmental “bads” and subsidizing environmental “goods,” while simultaneously achieving income redistribution is typical of the kinds of policies needed to bring the environment to the forefront of political decisions^[64].

Reduce, Reuse, Recycle (3R) Policy in Japan

The Basic Law for Establishing the Recycling-based Society, enacted in 2000, seeks to lower waste volume (see Table 10.2) To make the law operational, the Fundamental Plan for Establishing a Sound Material-Cycle Society was formulated in 2003 for implementation over 10 years^[65]. In addition to calling for greater recycling, disposal and collecting facilities, the law assigns an extended producer responsibility (EPR) to businesses that produce and sell products. EPR functions through a take-back requirement, deposit refund schemes and the shifting of financial and/or physical responsibility of a product at the post-consumer stage upstream to the producer. A policy on EPR has been introduced for containers, packaging and some household appliances.

The achievements of the policy so far have been encouraging, with an increase in the number of units recovered (post-consumer use) at designated collection sites in 2003 and 2004, of 3 and 10per cent respectively, compared with 2002^[66].

The circular economy in China

The circular economy covers production and consumption involving diversified sectors of industry, agriculture and services, as well as the industry of comprehensive recovery and utilization of resources from wastes and scrap^[67]. Production is addressed at three levels in terms of establishment of small-scale cycling, focusing on clean production in enterprises, intermediate-scale cycling in eco-industrial parks, and large-scale cycling in eco-industrial networks in various localities. The circular economy is aimed at the renovation of conventional industrial systems, targeting improvements in resource and energy efficiency and decreasing environmental loads. Steps have also been taken to establish sustainable consumption mechanisms, including the advancement of green procurement by the government.

The government has set the following national targets for 2010 using 2003 indicators as the baseline^[68]:

• resource productivity per tonne of energy, iron and other resources increased by 25 per cent;
  

• energy consumption per unit of GDP decreased by 18 per cent;
  

• average water use efficiency for agricultural irrigation improved by up to 50 per cent;

• reuse rate of industrial solid waste raised above 60 per cent;

• recycle and reuse rate for major renewable resources increased by 65 per cent; and
  

• final industrial solid waste disposal limited to about 4.5 billion tonnes.

Table 10.2 Quantitative targets for Japan’s 3R Policy for 2000–2010.

Implementation of the circular economy policy has been fairly recent, involving 13 provinces and 57 cities and counties nationwide. A relatively small number (5,000) of enterprises have passed the assessment for clean production and 32 enterprises have won the title of National Environmentally-friendly Enterprises. China’s efforts to decouple economic growth and resource consumption warrant close monitoring over the next few years.

Lead markets for environmental innovations

The emergence of lead markets, such as for the use of wind energy, requires political will, a long-term and integrated strategy and favorable conditions such as for innovation. (Credit: Jim Wark/Still Pictures)

Environmental innovations are typically developed in “lead markets”^[69] . These are countries that lead in adopting innovation, and where the penetration of markets is more encompassing than in others. They serve as a model for, and their technologies and related policies are often adopted by other countries. The concept of lead markets has been developed and fruitfully applied for many types of technological innovations, such as the mobile phones that were introduced in Finland, the fax in Japan or the Internet in the United States^[70]. Lead markets for environmental technologies are typically not only stimulated by more pronounced environmental preferences of consumers in that country, but also depend on special promotion measures, or on direct political intervention in the market.

Examples of environmental protection lead markets include the legally enforced introduction of catalytic converters for automobiles in the United States, desulfurization technologies in Japan, Danish support for wind energy, the waste from electrical and electronic equipment directive of the European Union and CFC-free refrigerators in Germany^[71]. Another example is the global distribution of chlorine-free paper. This initially involved political activities by Greenpeace, and support from the US EPA in the United States. There was the introduction of chlorine-free paper whitener in Scandinavian countries, Germany and Austria, and effective political market intervention in Southeast Asian countries^[72]. This shows that political action that stimulates internationally successful innovations is not limited to governments, but that environmental activists can also intervene effectively.

The emergence of lead markets is not a matter of introducing a single policy instrument. Instead, political will, a long-term and integrated strategy, and favorable framework conditions (for example, for innovation) are decisive^[73]. Most important is the strong correlation between economic competitiveness and environmental policy performance^[74]. The development of lead markets requires an innovation-oriented and ambitious environmental policy, integrated in a comprehensive innovation and industrial policy^[75]. Countries that attain the image of pioneers in environmental policy making are more successful in setting global standards^[76].

Lead markets fulfil a range of functions. From an international perspective, they provide marketable solutions for global environmental problems. Lead markets in high-income countries are able to raise the necessary funds for the development of technologies, which may assist them through teething troubles. By demonstrating both technical and political feasibility, they stimulate other countries and enterprises to adopt their pioneering standards. From a national perspective, ambitious standards or support mechanisms may create a first-mover advantage for domestic industries. Furthermore, ambitious policy measures can attract internationally mobile capital for the development and marketing of environmental innovations. Finally, these economic advantages legitimate the national policy-makers, and an ambitious policy provides them with an attractive, influential role in the global arena.

Transition management in the Netherlands

Against a common failure of environmental policy to effectively transform large technological systems, the concept of transition management has been developed in the Netherlands^[77]. The concept focuses on “system innovations,” which are defined as fundamental changes of technical, social, regulatory and cultural regimes, which, in their interactions, fulfil specific societal needs, such as transport, food, housing, water and energy. A system change requires co-evolution of technologies, infrastructure, regulations, symbols, knowledge and industrial structure. Historical examples of system innovations are the transition from wind-powered to steam-powered ships, or from wood-based energy to coal-based energy. Such system changes typically require a time frame of 30–40 years^[78].

Such a long time frame and the necessary encompassing changes are not manageable by conventional governmental steering. Traditional policy making is segmented in specialized departments, and as is the case for most business actors, is rather short-sighted. Transition management is proposed to provide advanced performance in steering system innovations. However, transition management includes no claim to actually plan transitions, but instead aims to influence the direction and speed of transition processes. The process can be divided into four distinct phases:

• creation of an innovation network (transition arena) for a defined transition problem that includes representatives from government, science, business and NGOs (Non-Governmental Organization);
  
• development of integrated visions and images about possible transition paths that span 25–50 years, and, based on these visions, derivation of intermediate objectives;
  
• the execution of experiments and concerted actions according to the transition agenda (experiments may refer to technologies, regulations or modes of financing); and
  
• monitoring and evaluation of the process, and implementation of the results of the learning processes.

Successful experiments need to be taken up by the policy process and their diffusion promoted.

Several projects have been underway in the Netherlands since 2001 to experiment with this strategy. Though transition management is not expected to yield immediate results, initiatives in the energy sector indicate that the processes have led to:

• more integration of existing policy options and approaches;
  

• development of coalitions and networks among stakeholders (from 10 in 2000 to several hundred by the end of 2004);
  

• more investments (from about US$200 000 in 2000 to US$80 million in 2005) including “relabeled” and additional funds; and
  
• more attention to the issues with a long-term perspective^[79].

Improving consideration of the environment in development decision making

Governments pursue a range of different, sometimes even competing or conflicting objectives. While the division of labor among government departments can be effective and efficient, it is less effective for cross-cutting issues, such as protection of the environment. Even worse, environment is often treated as just one more sector to be balanced against other social objectives, rather than providing the foundation on which all life depends. There has been limited progress in moving environmental considerations from the margins of economic and social decision making, but much more needs to be done.

Environmental policy integration

The need to incorporate environmental concerns into the decision making procedures of non-environmental policies has been a constant challenge for better government. Previously, environmental policy integration (EPI) was the responsibility of environmental agencies alone. However, it proved to be difficult to effectively interfere in the policy domains of other departments. Therefore, a number of countries shifted the responsibility for integrating environmental concerns towards the sectors themselves. This means that government departments that previously were opposed to a comprehensive greening of their policies, such as those responsible for transport, industry, energy and agriculture, must become responsible and accountable for their environmental performance (see Box 10.3).

Such an approach can be seen as “governmental self-regulation.” It is up to each department to choose the best means for incorporating environmental objectives in its portfolio of objectives, in a consistent national strategy, and to report on the outcomes. For example, many ministries of industry have established eco-industrial parks or industry clusters with advanced waste treatment systems^[81]. To make such a shift in responsibilities work, however, there is a need for high-level commitment by cabinet or parliament, or a clear lead by a designated ministry, and also a need for clear and realistic objectives, indicators and benchmarks, as well as for provisions for monitoring contents. The Cardiff Process in the European Union can be seen as one model for this type of EPI^[82].

Policy appraisal and impact assessment

Fig 10.4 A continuum of SEA application.^[1]

Tools for incorporating environmental concerns into other sectoral policies include strategic environmental assessments (SEA) (Figure 10.4), regulatory impact assessments^[83] and other forms of policy appraisal (see Chapter 8). These instruments aim at identifying possible unwanted side effects and conflicts of interests during the formulation of policies. Typically, plans, programs and policies are assessed against a number of criteria by the government agency itself. While offering great potential for learning and increased transparency^[84], the findings are rarely used. The United States and Canada were pioneers in introducing environmental assessments for planned policies in the 1970s. SEA was rediscovered by the European Union in the 1990s. However, SEA application is generally limited to plans, policies and programs that have a direct impact on the environment^[85]. Generic policies are usually exempted from the need to conduct an assessment of their environmental impacts, although these could be considerable. Examples include SEAs of multilateral bank plans and programs, the United Kingdom’s integrated policy appraisal and regulatory impact assessments, the European Union’s integrated assessment, and Switzerland’s sustainability assessment^[86]. Recently, there has been a trend towards integrating the requirements to assess impacts, such those as on gender, business, SMEs, environment and the budget, in a single, comprehensive procedure or integrated assessment (IA). Initially, the focus of IA was restricted to minimizing costs for business actors and increasing the efficiency of regulation. This form of regulatory IA did not pay much attention to unintended side effects or non-market effects^[87]. IA aims at analyzing a wide array of generic aspects, such as enhancement of competitiveness, support for small and medium enterprises, consideration of gender aspects or consideration of environmental concerns. Such an integrated perspective aims to reveal conflicts between objectives, or to identify win-win solutions. Denmark, Canada, the Netherlands, Finland, Sweden and the United Kingdom have been main forerunners, although it is significant that Poland is now requiring sustainability impact assessments. This trend reflects a growing insight that side effects, interlinkage effects or non-market effects may have severe implications in other policy areas, and, therefore, need to be taken into account.

Although IA is a rather generic tool, it has the potential to improve EPI, because it requires ministries or agencies to consider environmental concerns early in the process of policy formulation. Furthermore, these other sectors are required to consult environmental ministries, agencies and relevant stakeholders early in the process. Some initial evaluations of IA schemes, however, demonstrate the possibilities to misuse such approaches to roll back environmental concerns under the rubric of a better regulatory agenda^[88].

Ultimately, the effectiveness of various forms of environmental assessments will be judged on how they influence policy processes to better manage the environment and enhance human well-being.

Decentralization and delegation

Another innovative approach to integrating environmental concerns in policy making is the inclusion of environmental objectives in controlling systems. New public management gives more discretion to the different units and levels of policy making. In many countries, control by central departments is exerted by adapting controlling mechanisms to delegated governmental units.

There are some generic lessons to be drawn from existing examples of decentralization, and the integration of environmental concerns.

• To close the gap between rhetoric and hard action in sectoral strategies, regular evaluation is necessary. This can be performed by regular reporting to parliament or the cabinet on progress achieved in implementing the plans. In some countries, the national audit office is mandated to audit and report on the environmental and sustainable development performance and financial management of their respective governments. Canada appointed an independent Commissioner of the Environment and Sustainable Development in the Office of the Auditor-General, while New Zealand established an independent Parliamentary Commissioner for the Environment. The evaluation by review through international organizations has proven to be influential in the case of OECD^[89]. The OECD environmental performance reviews also help member states monitor the implementation of their own policies and achievements in meeting their own targets. Recently, the European Commission initiated a review of the National Strategies for Sustainable Development of its Member States^[90].
  

• The decentralization of responsibility for the environment increases transparency regarding environmental performance and policies of the different governmental sectors.
  

• The initial momentum for decentralization often comes from a central institution in government, such as the prime minister, the cabinet or the parliament. However, EPI is unlikely to remain prominently on the political agenda of these institutions for long. Therefore, it is necessary for this initial momentum to be used to quickly integrate EPI into regular procedures and institutions of policy making.
  

• For sustained integration of environmental concerns, it is necessary to couple EPI with the financing mechanisms of government. A number of countries experimented selectively with defining environmental criteria for their spending programs for infrastructure, and regional and structural development. But, few countries have conducted an in-depth expenditure performance review to reveal spending that is contradictory to environmental objectives (see Box 10.3).
  

Beyond environmental agencies

Requirements to routinely report on environmental impacts, and appraisal of sectoral policies tend to keep the environment high on the agendas of non-environmental sectors of government. However, for effectiveness these reporting requirements have to be supervised by independent organizations with a strong mandate. In some countries, environment ministries oversee these activities. However, as junior ministries often they cannot prevail over more powerful agencies. In other countries, the responsibility has been shifted to the office of the prime minister. In a few countries (United Kingdom and Germany), national parliaments have set up committees to oversee these activities. Canada and New Zealand mandated the auditors-general to service the parliamentary committees. In some countries, although still underutilized, scientific advisers are assessing environmental policies (and their integration) on a regular basis^[91] and international policy assessment, comparisons and recommendations have been published in different fields by several research organizations. Environmental ministries do not become obsolete in these approaches, as they have to organize the knowledge base for policy making, provide indicators and data for monitoring and assessment, organize the political process to adopt goals and objectives. Ministries in interested countries could even join forces with the scientific community to utilize experience across the borders, and benchmark environmental performance of different sectors.

It is apparent that environment is moving closer to the core of societal concerns under increasing social pressure upon governments everywhere, and this has already produced a change in the meaning of moving environmental concerns “from the periphery to the core” in decision making. This includes a better understanding of the nature of the existing core of decision making and its drivers, and of the place and role of the environmental issues in it. For too long, the existing core of decision making has been organized around the preservation of a given set of conditions indispensable for the ceaseless accumulation of material wealth. Under that orientation, the environment is necessarily expressed as just another variable of economic policy, implying that nothing more than trade-off decisions are needed. Moving the environment from the periphery to the core of decision making means transforming the core so that eventually the economy and society are reoriented to achieve sustainable environmental quality and human well-being. This reorientation implies major educational, institutional and financial changes.

Conditions for Successful Implementation of a New Policy Framework

The drivers-pressures-state-impacts-response (DPSIR) framework is used as a basis for understanding interactions between people and the environment. While the proven problems have often been successfully addressed by targeting a single sector or a single link in the DPSIR chain, persistent problems are more likely to require multisectoral or cross-DPSIR approaches, particularly targeting drivers. The following sections review the types of structural innovations that could form the basis of a more ambitious global policy agenda.

Public awareness, education and learning

Collective learning^[92] and adaptive management^[93] are management approaches aimed at coming to grips with complexity and uncertainty. Implementers and other stakeholders at different levels are encouraged to collect data and information, and process it in a manner and format that provides feedback and self-learning. Capacity building support is being provided to improve indigenous and/or community-based systems of monitoring, and to relate it to higher levels of information aggregation and decision making. For instance,
