ABSTRACT
Production of biomass is directly dependent on the availability of water and prevailing environmental conditions. Production and use of biomass energy have direct impacts on the quality and quantity of water as well as on other environmental factors. The extent of biomass production and the environmental conditions in the rangelands of Sudan present the country with even more serious environmental, social and economic problems. For assured biomass production, water control is an essential requirement, since either too much or too little water is generally undesirable for biomass growth. The result could be regarded as a positive cycle of biomass production, with processing for energy generation and linkages with water. A direct benefit of increased biomass production through efficient water use will be the simultaneous increases in the availability of both agricultural residues that can then be used as an alternative source of energy, and raw materials such as com, sugarcane or sugar-beet for alcohol production.
