    For forecasting agricultural production to design cropping patterns and to utilize water effectively, a computerized agricultural production monitoring system named PDM was selected. The Nam Oon irrigation project was chosen as a case study. PDM was used for agricultural production forecasting in the Nam Oon project for ten cultivation seasons from the 1995 wet season to the 2000 dry season. The factors affecting flow in the canal and the agricultural production forecasting equation were also investigated.

    Various forms of coastal landuse covering study site (46,785.69 hectares) were observed to underwent changes as evidently detected between satellite images sensed in 1994 and 2001 at the Banten Bay. It was important to identify what these changes were. Therefore, appropriate change detection must be selected. The image preprocessing step involved removing errors from raster data. This was done by performing basic processes, such as, radiometric correction, geometric correction and image calibration.

    Conversion of climax Dipterocarp forest for agricultural purposes has resulted in a decline in productivity of light textured soils in Northeast Thailand. To quantify the degree of chemical degradation that these soils have undergone, a survey was undertaken of six paired sites where adjacent Dipterocarp forest soils were compared to continuously cropped systems that had been under production from 37-100 years. Surface charge fingerprints along with soil chemical and physical attributes were determined on selective depth intervals.
