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.
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.
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.
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.
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.
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.
With the addition of elevation and land use and land cover data, we can show population density on a map much more effectively than if we simply color census areas. The resulting maps should allow better planning, especially in highly developed areas.
The Crater Lake Data Clearinghouse website is a gateway to information and data on Crater Lake with links to data downloads of bathymetry, maps and imagery, a fly-by movie, photos, and information on geology, maps, history, and biota.
Database of mineral and material commodities with descriptions, contacts, and historical and current statistics of worldwide supply, demand, production and trade in Mineral Commodity Studies, Minerals Yearbooks, and special publications.
Statistics and information on worldwide supply, demand, and flow of minerals and materials essential to the U.S. economy, national security, and protection of the environment. Links to publications, recycling, and historical statistics.
With high property damage, loss of life and fire damage were relatively low. Why? The legal system encourages builders to follow code, the electrical grid was shut down early, and emergency response management was very effective.
Online map system providing downloadable geospatial data, primarily NSDI framework themes (that is, general geographic data such as transportation, boundaries, hydrography, orthoimagery, land cover, and elevation).
