Introduction
The technology available due to sensors is making it possible to achieve benevolent results that were formerly impossible. Information is made available with ease and precision.
Zambian authorities have recently used sensor technology to aid in resolving water shortages. Part of the Integrated Water Resource Management for Zambia (IWAREMA), funded by ESAs MERIS sensor aboard Envisat, an array of environmental maps were generated to deliver local policy makers options for effective water resource management.
Mapping out a plan
Maps were produced from the efforts elucidating existing water resources, suitable dam locations, and land cover. The projects primary concern is to protect Zambias ecosystems mainly in the Kafue flats, which grants water outlets for wildlife, agricultural activities, fisheries, and tourism.
The sensors immediately help with the water shortage, and offer long-term advantages. With access to the maps, authorities can determine the expansion of urban areas and loss of forest and agricultural areas, and assess the risk of erosion, fluctuation in water availability, and percentage of surface water (acting as...
