R. aOptimising land use and water allocation in intercropping systems. c2012 aThe main purpose of this study is to identify the optimum allocation of limited amount of land and irrigation water across a number of alternative farm enterprises, maximising the whole-farm profitability by considering present relative prices, changes in river water availability, irrigation system efficiency and a highly variable climate. It was developed an optimisation model by using linear programming language to maximise the whole-farm profit of farm located in Wee Waa (NSW, Australia), for three different scenarios (dry, average and wet years) over two seasons. The whole-farm profit is highly sensitive to climate variability and also to prices and yields variability, especially in relation to cotton. aCrop rotation aIrrigation aLinear programming aProfit maximization aWater aÁgua aIrrigação aProgramação linear aRecurso Hídrico aRotação de cultura aSistema de cultivo aConsórcio aMaximização de lucro1 aFIGUEIREDO, M.
