In modern livestock farming, where efficiency, sustainability, and resource optimization are vital, choosing the right farm location is crucial. This requires a meticulous assessment of environmental, economic, and social factors. Recently, the synergy of Geographic Information Systems (GIS) and the Analytic Hierarchy Process (AHP) has revolutionized site selection for multiple purposes. This study applied GIS and AHP approaches to find suitable locations for pig farming in Tan Yen district, Bac Giang province. A set of criteria reflecting social, economic and enviromental aspects of livestock farm was identifed through literature review and local authority consultation, then APH approach was applied to identify weights for each indicator. Finally, weighted overlay in GIS was applied to produce maps of different suitability levels (not suitable, less suiltable, suitable, and most suitable). Results of this study provide an approach and usefull information for local authority in land use planning, specifically to identify suiltable locations for pig farms that balance the social, economic and environmental factors.
