South Asia is gradually diversifying its crop sector in favour of high value commodities, especially fruits, vegetables and spices. If carried out appropriately, diversification can be used as a tool to augment farm income, generate employment, alleviate poverty and conserve precious soil and water resources.

In a runoff irrigation system using levelled basins, the water uptake patterns of different plant species (Acacia saligna (Labill.) H. L. Wend. and Sorghum bicolor (L.) Moench.) with contrasting root and shoot development were compared. Rainfall amounts during 1995 led to enough runoff water for realizing two cropping cycles. The amount of irrigation water was sufficient to fill the moisture-de...
Abstract Water allocation can be evaluated from various economic, environmental, food security, and climate aspects. This paper was conducted to develop an optimal water strategy with economic framework. A game theory has been used determine the planning structure. cooperative technique based on core solution, Shepley value, Nucleolus solution incorporated into decision-making system results of...
