520 _aThe study area is located in the Central Plain of Thailand which is about 80 km from Bangkok. The most important resource of the province is its deepwater rice areas which total 166,238 ha., representing 21 percent of the total deep water rice growing areas of Thailand. The drawback of increasing yield in this ecosystems is the damage caused by floods during the wet season. The Dikes and Ditches Project which aims to offset this annual inundation and provide water for the second rice crop, had by 1986 covered about 350,691 ha. with irrigation and drainage canals in at least eight provinces including Ayutthaya. This infrastructure had considerably altered the hydrology of the region deepwater rice environment. Existing Land use and Landcover map of the province broadly classified such areas as irrigated, uniformly suitable for double rice cropping. LANDSAT TM imagery taken during the wet and dry season of 1988 and 1989 clearly showed variation in water regimes, indicating double cropping was not practical over the entire command area. Using the image processing and GIS capabilities of ERDAS, plus other ancillary data, various thematic maps were produced. Results of the GIS analysis were maps of: updated Land use and Landcover; Planning; and Suitability for Rice and Upland Crops. A Cropping Intensity map indicates suitable areas for Rice-Rice, Rice-Upland crops patterns and areas where Rice alone can be grown. With these findings, rice growing in the Central Plain of Thailand, particularly deepwater rice, is on the brink of rapid change. A new form of cultivation in which the environment is remodeled to suit rice growing will be superimposed on the traditional rice cultivation, particularly where variations in water regimes occur. An alternative resource plan for the deepwater rice is being proposed, focused towards "environmentally benign" farming methods. Aside from rice, the province has other important resources which play a major role to its economy and that of the whole Kingdom. Running downstream to Metropolis Bangkok is the Chao Phraya River systems, which is being polluted. The Ancient City of Ayutthaya is an important tourist attraction but being exposed to "architectural pollution", (building modern edifice near them). The brick making industry is coming into conflict with crop intensification in the use of human and land resources. A proposed resource management planning structure is presented in view of streamlining government resource monitoring, planning and implementation. This starts "downstream" at the village level and stop "upstream" at the national level.
