Vital Climate Graphics Africa
This set of 25 graphics focuses on the special challenges that Africa faces due to expected long term changes in climate. The graphics indicate that temperature rise in Africa corresponds to global temperature rise, and that adverse impacts including extremes, are spread across the diverse environments of Africa, putting a huge proportion of Af ...

Population and development in Africa
As population increases, so does the demand for natural resources. This graphic shows how the world's population distribution has changed since 1750 (in 50-year increments), with projections for 2050 and 2150. It also sh...

Deforestation in West Africa: Case Cote-d'Ivoire
The average annual rate of change in total forest area from 1990 to 2000 for the whole of Africa was estimated to be -0.74 %, equivalent to losing more than 5 million ha of forest a year, an area roughly the size of Togo...

Carbon Dioxide (CO2) emissions for selected African countries in 1997
Africa is very vulnerable to climate change given its low capacity to respond and adapt, but Africa emits relatively low amounts of greenhouse gases in comparison to other regions. This graphic shows the amount of carbon...
