Forest and Biodiversity under Threat by Economic Development Forest and Biodiversity under Threat by Economic Development
Southeast Asia, containing the world’s third largest tropical forests, is experiencing deforestation rates higher than almost anywhere else on Earth. The region’s forests and animals living in the forest are endangered by defragmentation and conversion to agriculture or other land uses, such as oil palm plantations and logging.

Forest Carbon Stock per Region Forest Carbon Stock per Region
Carbon stocks in land based ecosystems are distributed irregularly between tropical and northern latitudes but are mostly concentrated in forest ecosystems and wetlands. Recent research suggests tropical forests play an even more important role in absorbing carbon than previously thought, taking up 1 Gt of carbon every year, or about 40 per cent of the total for land based absorption (Britton et al. 2007).

Growth of Cattle Breeding in Amazonia Growth of Cattle Breeding in Amazonia
In Latin America, cattle ranches are expanding rapidly (FAO 2007a) and, according to one study, accounted for an estimated 70 per cent of deforestation in Brazil in 2007 (Malhi et al. 2008). In the Brazilian Amazon region, ranches cover an area of at least 8.4 million hectares in total.

Estimated Loss of Plant Species 2000-2005 Estimated Loss of Plant Species 2000-2005
The present environmental situation – heavily influenced by climate change – could lead to a massive destruction of forests and the extinction of countless species. For example, modelling focusing on the Amazon region has indicated that 43 per cent of 193 representative plant species could become nonviable by the year 2095 due to the fact that changes in climate will have fundamentally altered the composition of species habitats (Miles...

Breakdown of Carbon Storage by Region Breakdown of Carbon Storage by Region
Forests absorb carbon through photosynthesis and sequester it as biomass, thus creating a natural storage of carbon. Carbon stocks in forest areas comprise carbon in living and dead organic matter both above and below ground including trees, the understorey, dead wood, litter and soil.

Radioactive, chemical and biological hazards in Central Asia Radioactive, chemical and biological hazards in Central Asia
The Soviet development model for Central Asia was based on building large-scale irrigation schemes enabling the region to become a major cotton producer and expanding the mining and processing industry. Industrial operations in the region paid little attention to the environment and public health, resulting in the accumulation of pollutants in the local environment. Today, not only active industrial facilities constitute a threat to environment, ...

Global freshwater withdrawal Global freshwater withdrawal
World map showing annual levels of renewable water resources for the year 2000 measured in cubic meters. The use of water varies greatly from country to country and from region to region. 'Withdrawal' refers to water taken from a water source for use. It does not refer to water 'consumed' in that use.

Global atmospheric concentration of CO2 1870-1990 Global atmospheric concentration of CO2 1870-1990
Historically the developed countries of the world have emitted most of the anthropogenic greenhouse gases. The U.S. emits most in total, and is one of the countries with highest emissions per capita. China is the second largest emitter, but has very low emissions per capita. Over the last 20 years, industrial development has led to a rapid rise in the volume of emissions from Asia, but on a per capita basis, emissions in this region are still at ...

Regulation of the Tigris and Euphrates rivers Regulation of the Tigris and Euphrates rivers
Water has long been associated with conflicts between neighbouring countries. This graphic shows how water from the Tigris and Euphrates rivers is used in Iraq, and that neighbouring Syria and Turkey influence the flow of this water. The graphic shows the locations of main dams, swamps and horticulture in the region. It also shows five of the major ways in which land is used in the region: forest and grazing land; rain-fed agriculture (grains, ve...

The Global International Waters Assessment (GIWA) is an example of a comprehensive strategic assessment designed to identify priorities for remedial and mitigatory actions in international waters. This graphic shows GIWA case studies for the Black Sea, the Amazon, the Great Barrier Reef and the Agulhas Current. Each case study includes an introduction and maps of the region and a discussion of the issues of concern for that region, such as freshw...

Global freshwater resources: quantity and distribution by region Global freshwater resources: quantity and distribution by region
Glaciers and icecaps contain approximately 70% of the world's freshwater, but groundwater is by far the most abundant and readily available source of freshwater. This graphic illustrates the quantity (in cubic kilometres) and distribution of the world's freshwater resources in glaciers and permanent ice caps, in groundwater, and in wetlands, large lakes, reservoirs and rivers. Further information is given in the accompanying text.

The world's surface water is affected by different levels of precipitation, evaporation and runoff in different regions. This graphic illustrates the different rates at which these processes affect the major regions of the world, and the resulting uneven distribution of freshwater. It shows the amount of precipitation in cubic kilometres for each region, and the percentage of that amount which evaporates or becomes runoff. The text below the grap...

Distribution of coral, mangrove and seagrass diversity Distribution of coral, mangrove and seagrass diversity
Similar to corals, the region of greatest mangrove diversity is in Southeast Asia, particularly around the Indonesian Archipelago (Burke et al., 2001). There are three distinct areas of seagrass diversity in the Pacific region: the Indo-Pacific (areas around Indonesia, Malaysia, and Papua New Guinea), the seas around Japan, and southwest Australia (Spalding et al., 2002). This graphic illustrates the distribution and biodiversity (low, medium and...

There is growing evidence that many marine species are less widely distributed, and therefore more vulnerable to extinction, than previously thought. This graphic shows the diversity of marine mammals, sharks, molluscs, birds, and shrimps and lobsters in the world's marine areas. The data have been modified to show the species diversity of each region as a fraction of the most species-rich region.The maximum number of marine mammals species in a ...
