An integrated computer program called Cropping System and Water Management Model (CSWM) with a three-step feature (expert system-simulation-optimization) was developed to address a range of decision support for rainfed farming, i.e. crop selection, scheduling and optimisation. The system was used for agricultural planning with emphasis on sustainable agriculture in the rainfed areas through the use of small farm reservoirs for increased production and resource conservation and management. The application of the model was carried out using crop, soil, and climate and water resource data from the Philippines. Primarily, four sets of data representing the different rainfall classification of the country were collected, analysed, and used as input in the model. Simulations were also done on date of planting, probabilities of wet and dry period and with various capacities of the water reservoir used for supplemental irrigation. Through the analysis, useful information was obtained to determine suitable crops in the region, cropping schedule and pattern appropriate to the specific climate conditions. In addition, optimisation of the use of the land and water resources can be achieved in areas partly irrigated by small reservoirs.
一个名为作物种植系统与水资源管理模型（CSWM）的集成计算机程序被开发出来，它具有三个步骤的功能（专家系统 - 模拟 - 优化），旨在为雨养农业提供一系列决策支持，即作物选择、种植安排和优化。该系统用于农业规划，重点是通过利用小型农场水库来增加产量、保护和管理资源，从而实现雨养地区的可持续农业。该模型的应用是利用来自菲律宾的作物、土壤、气候和水资源数据进行的。主要收集、分析了四组代表该国不同降雨分类的数据，并将其用作模型的输入。还针对种植日期、干湿期概率以及用于补充灌溉的不同容量水库进行了模拟。通过分析，获得了有用信息，以确定该地区适合的作物、适合特定气候条件的种植时间表和模式。此外，在部分由小型水库灌溉的地区，可以实现土地和水资源利用的优化。
