Aridity Zones
Forty percent of Africa's population lives in arid, semi-arid, and dry subhumid areas. Climate change may lead to an increase in arid zones that are susceptible to drought. This graphic shows the locations of humid, mois...

Selected impacts of climate change in the Caspian Sea region
As the concentration of greenhouse gases in the atmosphere increases, the temperature in the European part of the Caspian Sea region will continue to rise, at least at first. Some researchers have recently expressed fear...

Precipitation changes: trends over land from 1900 to 2000
Precipitation has very likely increased during the 20th century by 5 to 10% over most mid- and high latitudes of the Northern Hemisphere continents, but in contrast, rainfall has likely decreased by 3% on average over mu...

Water withdrawals in 2050
Current patterns of human use of water are unsustainable. From 5% to possibly 25% of global freshwater use exceeds longterm accessible supplies and is met through engineered water transfers or the overdraft of groundwate...

Unsustainable water withdrawals for irrigation
The imbalance in long-term water budgets necessitates diversion of surface water or the tapping of groundwater resources. The areas shown with moderate-to-high levels of unsustainable use occur over each continent and ar...

Projected impacts of climate change
Global climate change may impact food production across a range of pathways (Figure 17): 1) By changing overall growing conditions (general rainfall distribution, temperature regime and carbon); 2) By inducing more ex...

Selected drought events in Africa, 1981-1999, and livestock impacts
Water scarcity in terms of drought or depleted groundwater could therefore have great impacts on livestock and rangelands. These interactions are also complex. While drought can directly threaten livestock, other fact...

Population density in drylands of the World
Drylands, the arid regions of the World between temperate regions and deserts, are subjects to long seasons with very little precipitation and drought spells sometimes lasting over several years. The most densely populat...

Natural hazard hotspots, by risk type
Disasters and natural hazards represents one strong aspect of vulnerability for the exposed and poor of the World. With climate change, the frequency of certain natural hazards are expected to increase. This map presents...

Cereal productivity in sub-Saharan Africa under a projected Intergovernamental Panel on Climate Change (IPCC) scenario
A majority of the population in sub-Saharan African lives in rural areas, where income and employment depend almost entirely on rain-fed agriculture. This population is today at high risk. Sub-Saharan Africa already has ...
