Agriculture land use distribution - croplands and pasture land Agriculture land use distribution - croplands and pasture land
The World's agricultural land is used in different ways, depending on climatic and soil factors, but also related to cultural and social issues. The majority of croplands, where rice, wheat, legumes and corn - among other crops - are spread out in the Northern Hemisphere, in the temperate zone, and in South and Eastern Asia. Areas where primarily livestock is held for agricultural are dominant in Africa, South America and Australia.

Coastal population and altered land cover in coastal zones (100 km of coastline) Coastal population and altered land cover in coastal zones (100 km of coastline)
Coastal areas with high population densities are those with the most shoreline degradation or alteration. Densely populated areas close to seas are also the most attractive for a lot of economic activity. The graphic shows the proportion of the population that lives within 100 km of the coast, for each of the world's nations and where there are coastal zones with high degree of human alteration (compared to 'natural' landcover). In addition, the ...

Status of inequitable access to land and natural resources, 2005 Status of inequitable access to land and natural resources, 2005
Strong access to land and natural resources have been found to be associated with increased economic growth among rural poor in developing countries. The study behind the data in the map examined the status on access to land and natural resources in selected countries, and created an index on the degree of concern. Strong rights to land empowers communities and families, and enables them to take charge over their future.

The composition and levels of wealth per capita for low-income countries The composition and levels of wealth per capita for low-income countries
In low-income countries, the natural section represents a quarter of the total wealth, this represents the land that is managed either by household, individual or communally, and the potential for generating income. Physical capital, represents a much smaller share as people will have less potential, compared to higher income countries, to acquire equipment, structures and infrastructure.

World Greenhouse gas emissions by sector World Greenhouse gas emissions by sector
All data is for 2000. All calculations are based on CO2 equivalents, using 100-year global warming potentials from the IPCC (1996), based on a total global estimate of 41 755 MtCO2 equivalent. Land use change includes both emissions and absorptions. Dotted lines represent flows of less than 0.1% percent of total GHG emissions.

The water cycle The water cycle
Environment water transport system. The water cycle consists of precipitation, vapour transport, evaporation, evapo-transpiration, infiltration, groundwater flow and runoff. Figure 1 explains the global water cycle, illustrating how nearly 577,000 km3 of water circulates through the cycle each year. A table of estimated residence times shows the approximate times that water resources exist as biospheric water, atmospheric water and so on. The w...

Fish diversity in freshwater systems Fish diversity in freshwater systems
Although freshwater ecosystems such as rivers, lakes and wetlands occupy less than 2% of the earth’s total land surface, they provide a wide range of habitats for a significant proportion of the world’s plant and animal species. Many are yet to be discovered, but the number of freshwater species worldwide is estimated at between 9,000 and 25,000 (Cosgrove and Rijsberman, 2000). However, this number is rapidly decreasing due to human interference....

The Mekong River - survival for millions Following the course of the Mekong River helps to understand the human/river hydrological interdependence. From its source on the Tibetan Plateau it drops 5,000 metres and flows across six countries before reaching its delta. More than a third of the population of Cambodia, Lao PDR, Thailand and Vietnam - some 60 million people - live in the Lower Mekong Basin, using the river for drinking water, food, ir...

Planet index 2007 for marine species population Planet index 2007 for marine species population
The Marine Species Population Index provides an assessment of the average changeover time in the populations of 217 species of marine mammals, birds, reptiles, and fish. The index represents the average value of six regional ocean indices. More pronounced declines are seen in the southern oceans, attributed to the fact that major losses and degradation of marine ecosystems in the industrialized world took place prior to 1970. Marine species are ...

Trends in capture fisheries and aquaculture Trends in capture fisheries and aquaculture
The levelling off of the global fisheries catch reflects a growing decline in most major fishing areas. Today, these fishing areas are producing lower yields than in the past, and it is unlikely that substantial increases will ever again be possible (FAO, 2000). Inland and marine aquaculture production grew by about 5% annually during the 1950s and 1960s, by about 8% per year during the 1970s and 1980s, and by some 10% per year during the 1990s ...

This graphic illustrates the strong link between areas with high densities of industrial activity and zones of seasonally oxygen-depleted waters. There is a strong link between areas with high densities of industrial activity and zones of seasonal oxygen-depleted waters. In recent years there has been an increasing focus on treating and reducing municipal and industrial waste, and on reducing nitrogen levels in agricultural runoff. However, less...

Victims and affected people in Pakistan flood, August 2010 Victims and affected people in Pakistan flood, August 2010
Seasonal fooding can occur along all the major watersheds in the Himalayan region (Figure 11–14). The largest problems occur in food prone areas with high population densities. This includes parts of northeast India, south-central Nepal, central and southern Pakistan, large parts of Bangladesh and lower reaches of the large rivers in China. In India around 40 million people are affected by fooding annually and the damage has been estimated...
