Abstract: The sustainability of the watershed is affected by the activities and behavior of people around it. Determination of agricultural superior commodities that are based on environmental, economic and social sustainability is a resource based theory in realizing the further stages of agricultural management from the complexity of the interrelations that occur in the watershed. The aim of the study was to analyze the integration Multicriteria Analysis (MCA) Land Suitability and GIS approach to determine the superiority commodity of agricultural critical land in the Welang Watershed. Respondents in this study amounted to 110 people. The results showed that physical, soil and agroclimate properties analysis showed that the suitability of land suitable for upland plots in actual and potential for vegetable crops was potato plant while for food crop was corn. The highest income farming for food crops is corn, meanwhile in vegetable garden plant is known potatoes have been highly income. In social dimension approach community aspiration as important thing when decide critical land farming. AHP analysis can be concluded that erosion and temperature became main priority to agriculture cultivation especially in upland subsystem in watershed. Overall, AHP results have consistent values and accurate for decision making.
