Concrete evidence in the effectiveness of the farm ponds in the Northeast of Thailand has been presented. The case of the NE clearly indicates the development of rainfed into ir rigated landscape, improvement of the seasonal yield, the various sub-systems that can be derived leading to profitability and sustainability in the farm. The size of farm ponds in the three sites was estimated to be significantly smaller but has been considered by the farmers to have significantly changed their farming options. Increasing the size of the farm pond allows shifting from nearly total rice sub- system to a kind of vegetable sub-system following the different existing crop combination and aquaculture to attain the maximum profit during the wet and dry seasons. Results from the LP model obtained for four options proposed were compared with existing systems revealed that feasibility for significant increase in farm net income; maximum being the Option-1 in medium farm (supplementary feeding) with baht 1,840,183 increased from baht 134,931, and Op tion-1 in small farm baht 596,022 increased from 65,428. Findings of the optimum farm pond size and best combination of sub-system through water balance simulation and LP models helped to identify which is profitable as well sustainable.
