A community of practice that recognizes the interconnections between the health of ecosystems, wildlife, and humans and meets to facilitate the exchange of ideas, data, and research opportunities.
Information on the Interagency Hydrology Committee for Alaska, an organization of technical specialists at the federal, state, and local levels who are coordinating the collection and implementation of water resources related data in Alaska.
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.
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.
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.
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.
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
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.
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.
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.
