Etosha Pan halophyticsLast Updated on 2014-12-25 14:39:41
WWF Terrestrial Ecoregions Collection
The Etosha Pan Halophytics ecoregion is the relict landform of a prehistoric expansive, inland Pliocene lake. Today, the Etosha Pan is mostly an arid, saline desert. Typically, the intensively cracked, whitish clay is split into hexagonal salt-encrusted fragments, and wildlife is sustained only by scattered freshwater springs, which manifest as watering holes. These springs attract a diverse array of large mammals, especially during the dry season, making Etosha Pan a popular tourist destination. In unusually wet years, when the Ekuma, Oshigambo and Omuramba Ovambo Rivers receive sufficient rainfall, the pan is temporarily transformed into a shallow lake.
When surface water is present, it can be classified as a hypersaline lake, due to the elevated salinity. The Etosha Pan halophytics is considered within the... More »
DenmarkLast Updated on 2014-12-19 12:32:19Denmark is a nation of just over five-and-a-half million people in Northern Europe, bordering the Baltic Sea and the North Sea, on a peninsula north of Germany (Jutland) and includes roughly 500 islands, including several major islands (Sjaelland, Fyn, and Bornholm). It is a part of the generally fertile and mostly agricultural region known as the North European Plain. This entire region is generally flat to slightly rolling and is overlain with glacial deposits.
Denmark also includes the Faroe Islands and Greenland.
Its major environmental issues include:
air pollution, principally from vehicle and power plant emissions;
nitrogen and phosphorus pollution of the North Sea;
drinking and surface water becoming polluted from animal wastes and pesticides
Flooding is a threat in some areas of the country (e.g., parts of Jutland, along the southern... More »
Marine biodiversityLast Updated on 2014-12-15 19:53:24Biodiversity is now commonly defined as the variety of life in genes, species and habitats. According to the definition of the Convention on Biological Diversity, biodiversity is the variability among living organisms from all sources, including inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems.
The three domains of life, bacteria, archaea and eukarya are present in the marine environment. In addition there are viruses. About 230,000 species of marine plants and animals have been scientifically described and a few thousand bacteria and archaea. This known biodiversity only represents a small fraction of the number of species existing, except for the macrophytes and seagrasses which are living in coastal environments and, in general, for the pelagic...

Malaysia- FAO's Information System on Water and AgricultureLast Updated on 2014-12-07 21:15:44
Malaysia is situated in southeast Asia. It consists of two regions: peninsular Malaysia in the west lying between Thailand and Singapore, and the states of Sabah and Sarawak located in the east on the island of Borneo. The two regions are separated by the South China Sea. The total land area of the country is 328 550 km². Malaysia is a federal country, divided into 13 states plus the federal territories of Kuala Lumpur and Labuan Island..
The Food and Agriculture Organization of the United Nations (FAO) leads international efforts to defeat hunger. Serving both developed and developing countries, FAO acts as a neutral forum where all nations meet as equals to negotiate agreements and debate policy. FAO is also a source of knowledge and information.
In peninsular Malaysia, a mountainous spine known as Banjaran Titiwangsa sepa-rates the east of the... More »
Fisheries and aquacultureLast Updated on 2014-12-07 21:08:51
In 2002 the global production from fishing and aquaculture combined reached about 133 million tonnes. The global yield from capture fisheries is stagnating, but aquaculture has been expanding.
The quantities of fish captured remained stable at about 93 million tonnes per year between 1999 and 2002. China and Peru are leading the top ten of countries with the largest catches. The same countries have remained in the top ten for over a decade.
Oceans and seas provide 90% of the world's fishery catches. During the past decade marine catches brought to land increased slightly compared to the preceding decade. It should be noted that the quantity of marine fish caught and discarded fell by several million tonnes in the same time period. Trends vary greatly across different regions and for different species. The species yielding the largest harvest is the Peruvian... More »
