A climate trend analysis of Kenya-August 2010 [More info]-
Crop areas in west central Kenya are affected by decline in rainfall over several decades; the effects may be exacerbated by overall warming in the region
- A climate trend analysis of Sudan [More info]
-
The data shown here depict drying trends in one of
the world's most food insecure regions. Decreasing rainfall since 1980 accompanied increases in air temperature greater than global warming.
- Using observed warming to identify hazards to Mozambique maize production [More info]
-
Over 30 years of substantial warming, the timing of life cycle events in maize here has changed, threatening the crop yield by exposing the plant at sensitive phases in its life cycle to increased heat and drought, and lowering the weight of its grains.
- A Climate Trend Analysis of Burkina Faso [More info]
-
Summer rains have remained steady over the past 20 years, but are less than historic highs. Temperature has increased, and while the farmland per person is decreasing, population growth has been offset with improved yields.
- A Climate Trend Analysis of Niger [More info]
-
While summer rains have increased during the past 20 years, temperatures have increased as well, amplifying the effects of droughts. Crop yields are low but the population is growing, pointing to rising food insecurity.
- A climate trend analysis of Chad [More info]
-
Long-term reduction in rainfall and increasing temperature threaten Chad's future food production prospects; combined with rapid population growth and zones of substantial conflict, increasing numbers of people will be at risk.
- A climate trend analysis of Ethiopia [More info]
-
Recent trends in
March-June, June-September, and March-September rainfall and
temperature, identifying significant reductions in rainfall and increases
in temperature over time in this area.
- A climate trend analysis of Mali [More info]
-
Summer rains have remained steady for the past 20 years, but are below the long-term average. Current population and agricultural trends indicate increasing yields have offset population expansion, keeping per capita cereal production steady.
- A climate trend analysis of Uganda [More info]
-
Long-term reduction in rainfall and increasing temperature threaten Uganda's future food production prospects; combined with rapid population growth these factors could increase the number of people who are at risk during the next 20 years.
- A westward extension of the tropical Pacific warm pool leads to March through June drying in Kenya and Ethiopia [More info]
-
Analysis of sea-surface temperature in the Indian Ocean shows that warming correlates with east African rainfall; the effect on atmospheric convection and precipitation over the Indian Ocean is greater than that associated with El Niño (ENSO).
- Development of a global slope dataset for estimation of landslide occurrence resulting from earthquakes [More info]
-
