USGS responds to hurricanes [More info]
Information is provided about coastal impacts of Katrina, Rita, and Wilma and Satellite Imagery and other Geospatial Data, News Releases, Streamflow Conditions, publications and other resources.
On-line data and reports on acid rain, atmospheric deposition, and precipitation chemistry [More info]
Access to map of data collection sites of the National Atmospheric Deposition Program/National Trends Network (NADP/NTN) with links to other maps and reports on wet atmospheric deposition (chemicals deposited via rain, sleet and snow).
PDF 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.
PDF 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.
PDF 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.
PDF 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.
PDF 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.
PDF A climate trend analysis of Senegal [More info]
Modest declines in rainfall, accompanied by increases in air temperatures, declining farmland per person, along with trends in population and agriculture could lead to a 30% reduction in per capita cereal production by 2025.
PDF 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.
PDF 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.
