Optimal cropping patterns under water deficits
نویسندگان
چکیده
A mathematical programming model is proposed for optimal cropping patterns under water de®cits in dry regions. Crops may be deliberately under-irrigated in order to increase the total irrigated area and possibly the pro®t. An operating policy will identify both the total area and the irrigation level allocated to a given selected crop taking into account the possible successors and predecessors of this crop. Both annual and seasonal crops are examined in the same study. The model starts by identifying the optimal operating policy for each grower in the region having a given stock of irrigation water. Then, in order to allocate water eciently among growers, the model determines the global optimal cropping plan of the entire region. To solve eciently the problem, a decomposition algorithm is developed. Also some useful economic interpretations are given. Ó 2001 Elsevier Science B.V. All rights reserved.

ABSTRACT- Inadequate water supply is the major problem for agriculture in arid and semi-arid regions. Thus, effective management should be considered for water resources planning. In this research, a model was provided which is able to estimate optimal land and water allocation in the Doroodzan irrigation network. Optimal water management model was used at farm level to evaluate different defic...

We propose a Decision Support System (DSS) for optimal cropping patterns and irrigation water management. The development of the DSS has three objectives. The first is to use mathematical models in order to optimize cropping decisions and irrigation policies under shortage of water in the Kingdom of Saudi Arabia. The second is to help growers exploit optimally their lands in places suffering fr...

Water resources sustainability is one of the major issues in the agricultural sustainability. In this study sustainability of water resources has been investigated by use of linear and non-linear models in six models based on optimal utilization of water resources in the north parts farms of Iran because of incorrect use of agricultural water resources, from 2011 to 2012. Also “gross margin per...

Water shortage crisis is an issue that has led to drastic changes in different agricultural policies, especially in arid and semi-arid areas. Uncertainty in the amount of resources, e.g. water, used for agricultural production entails risk for farmers' income and cropping pattern changes. In the present study, the robust optimization model was used for optimal allocation of arable lands of Khor...
