LAND SUITABILITY ANALYSIS TOOLS FOR SUSTAINABLE MANURE UTILIZATION
Intensive livestock agricultural activities are a significant source of nutrient pollution that contribute to water quality degradation worldwide. The study presents a land suitability framework and an accompanying decision-making tool for sustainable manure management. The developed framework identifies potentially suitable areas for manure application from the user-defined area and further classifies the land as highly suitable, moderately suitable, marginally suitable, and unsuitable using seven environmental vulnerability factors considering landscape biophysical characteristics and proximity to streams. The decision-making tool built-in the ArcGIS environment was applied in a case study area in western Pennsylvania, USA. The tool classified 2% of the potential area as highly suitable and 21% as unsuitable for manure application. Landscape slope and proximity to streams were the dominant vulnerability factors in the case study area. The framework and tool are transferable across watershed boundaries and can help identify areas where environmentally sustainable animal agriculture can be developed.
