Abstract

Ta Dung Nature park is an important ecological region, its buffer zone currently has coffee as the main crop. However, declines in coffee yields result in a relative reduction in spending power by households. This study aimed to assess land potential to proposal the land for coffee cultivation. Sustainable agriculture must nurture healthy ecosystems and support the sustainable management of land and natural resources. An approach based on integrated use of the Analytical Hierarchy ProcessGeographic Information Systems and Remote Sensing (AHP-GIS-RS) developed using 13 environmental sub-factors. Study result showed the land of development of current coffee cultivation have had an effect from the most important criteria is soil type (0.24), followed by land use cover unit (0.17) and irrigation system (0.15). Sub-factors (SF9: rock expose above soil; SF11 : flood status, SF1 2: irrigation system) have the largest “potential” land for coffee plants. Coffee plantation was recommended to orient in 6,82 % total of study area by the possibility of expanding cultivated area. A framework of potential model was provided for other industry crops in other study areas in Vietnam.
