Consensus, or coming to agreement, is how a group of people can make a choice.Another way to arrive at a decision is for one person to make the choice.When it comes to the environment, consensus is difficult to achieve.The environment is everywhere. It is complicated.It affects everyone and every nation.The complexity and scale of the issues make it difficult to agree on what the problem is, what the solution should be and what action to take, especially on a world-scale where there are many factors that stress differences rather than what people have in common.Even at the local level, opinions cause conflict.Certain situations call for group decisions, others are more appropriate for a sole leader to choose or an individual to make personal a personal choice.This section includes major achievements in consensus and leadership on environmental protection; international treaties, reports and assessments, government legislation – proposed and current, and examples of regional, local and other movements.

Food SecurityLast Updated on 2014-09-24 23:01:45
A comprehensive definition of food security that is widely accepted today is that “food security exists when all people, at all times, have physical and economic access to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life"1. It follows from this definition that individuals and families who are not food-secure are likely to be hungry, undernourished or malnourished, poor, and living in places that are distant from well-stocked and functional food markets. These characteristics can often be observed directly or assessed through household survey methods.
While measures of nutritional status such as low height for age or low weight for height, average availability of food translated into calories available/day, per capita incomes, or distance from a market do not fully define food security, observations or... More »
Technological Nightmares (Lecture): Note on the “Precautionary Principle”Last Updated on 2014-07-01 15:53:44

There are two points of view when we face risk and uncertainties in our research. One is based on the precautionary principle. The precautionary principle says that when there is any risk of a major disaster, no action should be permitted that increases the risk. If, as so often happens, an action promises to bring substantial benefits together with some risk of a major disaster, no balancing of benefits against risks is to be allowed. Any action carrying a risk of a major disaster must be prohibited, regardless of the costs of prohibition.
The opposing point of view holds that risks are unavoidable, that no possible course of action or inaction will eliminate risks, and that a... More »
National Forest System (NFS) Roadless Area InitiativesLast Updated on 2014-07-01 15:36:04
Roadless areas in the U.S.National Forest System (NFS) have received special attention for decades. Many want to protect their relatively pristine condition; others want to use the areas in more developed ways.
Two different roadless area policies have been offered in the last decade. On January 12, 2001, the Clinton Administration’s roadless area policy established a nationwide approach to managing roadless areas in the National Forest System to protect their pristine conditions. The Nationwide Rule, as it will be called in this report, generally prohibited road construction and reconstruction and timber harvesting in 58.5 million acres of inventoried roadless areas, with significant exceptions. The Bush Administration initially postponed the effective date of the Nationwide Rule, then issued its own rule that allowed states to plan how roadless areas were managed. It issued a... More »
Total economic valuation of threatened and endangered speciesLast Updated on 2014-06-28 17:32:13[Authorship attribution for this article should be cited as John Loomis, Leslie Richardson and Arthur Edwards]
Protecting habitats for species threatened with or in danger of extinction is often aided by demonstrating the economic benefits to such protection comparable to the benefits of developing the habitat. The financial returns to commercial development are often obvious and concentrated in the hands of a few. The benefits of protecting threatened and endangered species (T&E) are widespread to hundreds of millions, if not several billion people on the planet. However, if the monetary benefits of protecting T&E species are not measured, then it appears that commercial development is of greater economic use than preservation of the habitat. This feeds the false dichotomy of the “economy versus the environment”. This article will show, the... More »
Ecosystems and Human Well-Being: Volume 1: Current State and Trends: Urban SystemsLast Updated on 2014-06-28 17:05:25This is Chapter 27 of the Millenium Ecosystem Assessment report Ecosystems and Human Well-Being: Volume 1: Current State and Trends

Urbanization and urban growth continue to be major demographic trends. The world’s urban population increased from about 200 million (~15% of world population) in 1900 to 2.9 billion (~50% of world population) in 2000, and the number of cities with populations in excess of 1 million increased from 17 in 1900 to 388 in 2000. As people are increasingly living in cities, and as cities act as both human ecosystem habitats and drivers of ecosystem change, it will become increasingly... More »
