Emissions per GDP in Latin America and the Caribbean, 2005 (excludes land use change)
Evidence at international level shows a positive, although not a linear, relation between GHG emissions and the trajectory of the gross domestic product (GDP). There is a strong heterogeneity in the ratio of emissions to...

Share of greenhouse gas emissions of Latin America and the Caribbean, 2005
Data on carbon dioxide emissions makes it possible to identify the main emitting countries within Latin America and the Caribbean. Chief among the emitters is Brazil, accounting for 52%, which together with Mexico, the B...

Threats to coral reefs in Eastern Africa
Human land use along coasts and in major river basins can threaten coral reefs through toxic material inputs to coastal ecosystems. This graphic shows the areas of low, medium and high estimated threats to coral reefs on...

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 othe...

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 b...

Biodiversity threats
South Africa is recognised as the third most megadiverse country in the world. The abundance of biodiversity found within its borders covers an estimated ten per cent of the world’s plant species, seven per cent of al...

Abatement costs for transition from undisturbed forest to other land uses
Opportunity costs for the transition from forest to other land uses between 1994-2009 in Tripa and 1990-2009 in Batang Toru are shown. For the transition to the most profitable land-use a price of slightly more than USD ...

Conversion of forests to different land uses
Using satellite images, land use changes were determined at Batang Toru (2001-2009) and Tripa (2001-2009) to calculate overall CO2 emissions. Deforestation in both areas led to different land use transitions, with the pr...

Conversion from primary forest to other land uses, 1985-2007
The main driver for forest loss on peat areas in the Leuser Ecosystem was oil palm development between 1985 and 2007, while for forest on non-peatlands other land uses than oil palm contributed more to land use changes.

Distribution of benefits under different land use scenarios in the Leuser Ecosystem
Net present value (NPV) is in millions of USD over a 30-year period (2000-2030) at a 4% discount rate. The NPV for local communities under a deforestation scenario would be 3,132 million USD and under a conservation scen...

Above-ground carbon-stock density changes
In Batang Toru, land use changes and deforestation led to an overall loss of around 10 tonnes of carbon per hectare between 1994 and 2009. Due to its exploitation for the cultivation of oil palm, the peat area of Tripa h...

Land use types that replaced forest in the Leuser Ecosystem during 1985-2007
The main driver for forest loss on peat areas in the Leuser Ecosystem was oil palm development between 1985 and 2007, while for forest on non-peatlands other land uses than oil palm contributed more to land use changes.
