Regional planning of pig husbandry with environmental protection using GIS

The pig husbandry has brought great social and economic benefits. But the intensive industrialization of pig husbandry has also created some environmental problems. In 1998, The Food and Agricultural Organization of the United Nation(FAO) carried out the Area-Wide Integration(AWI) researches and development project with the aim of significantly improving the development, increasing the economic benefit and reducing environmental impact of livestock husbandry. This paper describes the results of the AWI project in Wannian County, with respect to the evaluation for the spatial distribution and regional planning of pig husbandry. A site selection tool for future pig farms was developed and implemented by GIS. The use of the GIS tool will allow a more sustainable regional development of livestock husbandry and production.
