Abstract
Efficient use of water for agriculture production is highly emphasized by the Government of Pakistan due to limited available water resource s to meet the growing need of ever increasing population. With the passage of time w ater resources are depleting and becoming limited for food production . The freshwater that can be taped is only 0.007 % of the total available water . About 95% of the water is used for agriculture in Pakistan and produces m ore than 90 % food from irrigated agricultur al land . Huge water competition problems have to face by farming community in irrigated agricultur al areas in the form of low crop yields, water logging and salinity, lack of reservoirs, population pressure, etc. Drip irrigation system can help to use the scarce available water more efficiently. The potential areas for drip irrigation system are; areas of water shortage and valuable crops, fringe areas, s andy areas, etc. There is a need to develop energy and wa ter efficient irrigation systems to reduce the cost of micro - irrigation systems. The training of the farmers regarding installation, operation and maintenance is of vital importance in the success of these systems.

Research results reported in the United States indicate that yield of cotton is increased by more than 8 percent and 24 percent water is saved by drip irrigation
Summary
Efficient use of water for agriculture production is highly emphasized by the Government of Pakistan due to limited available water resources to meet the growing need of ever increasing population. About 95% of the water is used for agriculture in Pakistan and produces more than 90% food from irrigated agricultural land. Drip irrigation system can help to use the scarce available water more efficiently. Water plays an important part to fulfil the water requirements in photosynthesis. It helps in transportation of nutrients from soil to the plants which are essential for their growth. In order to increase yield of food products to fulfil the huge requirements world population in 21st century will need to bring about a «Blue Revolution» to balance the «Green. Pakistan has very poor water productivity (0.6 kg/m3) in comparison with India and California (1.5 kg/m3)
