Status of land tenure and property rights, 2005 Status of land tenure and property rights, 2005
Strong property rights have been found to be associated with increased economic growth. The study behind the data in the map examined the status on land ownership 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.

Climate Change Performance Index 2008 Climate Change Performance Index 2008
The Climate Change Performance Index developed by Germanwatch is calculated using three weighted indexes: *Emissions trends for energy, transport, industry and residential account for 50 % of total rating; *A country’s current emissions level (CO2 emitted per primary energy unit, primary energy unit per GDP, primary energy unit per capita) is given a 30 % weight in the overall evaluation; *Climate policy (national and international) weighs ...

Water Scarcity Index Water Scarcity Index
Water overuse is damaging the environment in many major basins. High overuse tends to occur in regions heavily dependent on irrigated agriculture, such as the Indo-Gangetic Plain in south Asia, the North China Plain and the High Plains of North America, and in areas undergoing rapid urbanization and industrial development. An estimated 1.4 billion people now live in river basin areas that are ‘closed’ (in that water use exceeds minimum recharge l...

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 ...

The WWF living planet index for freshwater The WWF living planet index for freshwater
'The over-exploitation and mismanagement of fisheries, particularly when combined with other man-made stresses, can lead to the collapse of regional fish faunas. In many countries, aquaculture is rapidly increasing in response to declining natural fisheries, often exacerbating the degradation of inland and coastal ecosystems through habitat alteration, pollution and the introduction of alien species' (Revenga et al., 1998). The Freshwater Specie...

UV Index Worldmap UV Index Worldmap
The Global Solar UV Index (UVI) is a simple measurement of the UV radiation level at the Earth's surface. It has been designed to indicate the potential for adverse health effects and to encourage people to protect themselves. The higher the Index value, the greater the potential for damage to the skin and eye, and the less time it takes for harm to occur. In countries close to the equator, the UVI can be as much as 20. Summertime values in nort...

Poverty and social unrest in South Africa Poverty and social unrest in South Africa
Although the United Nations Development Programme’s (UNDP) Human Development Index ranks South Africa as a middle-income country, the way in which income is distributed across the population is highly skewed. Some 39 per cent of the population, estimated at more than 49 million people, lives on less than R 388 a month. One consequence of poverty and high levels of unemployment is social unrest. A large proportion of South Africa’s poor population...
