'Water' the most essential input in bio-world has relatively been becoming more scarce with an increasing number of its users and uses. There is no absolute scarcity of water only the relative scarcity exists due to improper management practices while putting water to various uses. This paper has been developed with objectives (ⅰ) to highlight availability of water and its' different uses at existing level of use (ⅱ) to find out gaps between supply of and demand for water among competing uses with emphasis on irrigation and drainage (ⅲ) to suggest remedial measures for improving interactions of irrigation and drainage systems with psycho-socio-economic parameters in the light of environmental considerations. An economic analysis of getting economic optima through maximum sustainable yield and scoring technique reveals mainly productivity levels of food crops 4-5 times less than global levels. Although State receives, on the average, 152cms of rainfall and has many rivers, tributaries and lakes, yet only 20 per cent of total cultivated area has been found to be irrigated. The most of area in the State faces deficient rainfall by –20 to –59 per cent of the normal, leading thereby to low productivities in agriculture from small holdings (1.2 hectare). The State consumes about 92 per cent of utilizable water in agriculture and remaining portion in other uses like power generation, industry and domestic. The demand for water amongst these uses has been found to increase by about 3 to 4 times in the next twenty years, therefore an increase in gap between supply of and demand for water has been observed in future. Interactions among psycho-socio-techno-economic parameters reveal individual's attitude towards developmental efforts in water related projects which should be imaginative and creative on technical lines.
