Abstract | This research is an attempt to develop and evaluate a methodology for assessing the land use, analysing the land use change and impact for a representative watershed of humid tropics in the southern Philippines by integrating remote sensing and GIS technology. Digital elevation model, slope and drainage ancillary data are combined with remotely sensed satellite data in image processing and synchronic, diachronic and dynamic analysis of land use of the agroecosystem landscape of the watershed and trend of environment change of 1973 to 1994. The results show that during the period of 21 years, dramatic land use change took place resulting from rapid population increase and mismanagement. Agricultural area expanded to the high elevation area and steep slope at the expense of losing forest cover. There has been a general decline in the forest environment with different deforestation rate and extend during the period of 1973 to 1988 and the period of 1988 to 1994 respectively. The results also show that the sharply land use change and environment degradation ensued adverse impacts in this area, sustainable agriculture and natural resources management is needed. DEM, slope and drainage data are important ancillary data in integration of remote sensing and GIS. High resolution satellite have been found to be very suitable for land use mapping and monitoring. Combining ancillary data with remotely sensed satellite data has been found to be very effective to improve classification and obtain more detailed information about land use and land use change. GIS has been found to be very effective in analysing and evaluating of land use change and impact. With the application of GIS, a framework of monitoring land use change for future sustainable agriculture and natural resources management and development has been developed. Land use adjustment and development plan have been recommended. |
