Title: Rainwater Harvesting Techniques for Soil Moisture Conservation on the Upper Terraces of the Blue Nile-Sennar State (Sudan)
Author: Mohamed, Abdel Rahman; Hamid, Nour; Elamin, Abdel Moneim
Abstract: Although water may seem like a boundless resource, it is far from it. Only 2.5 percent of the planet's water is fresh, and 74 percent of that is tied up in the polar icecaps. Groundwater accounts for another 25 percent leaving just 1 percent of freshwater to be found in lakes, rivers, soil, and air. Due to population growth, drought, and pollution, groundwater resources are seriously declining. Today the world fights over oil; tomorrow (if not already) it will fight over water (Robin, 2005). Water harvesting is a proven technology to increase food security in drought prone areas. Erosion control and recharge of ground water are additional advantages of water harvesting techniques (FAO, 2000). Water harvesting techniques are practiced in the arid and semi-arid zones where annual rainfall is insufficient for plant requirements either for poor rainfall or rain water is not available to plant root zone.
