AN ECONOMIC ANALYSIS OF TARGETING SOIL CONSERVATION MEASURES WITH RESPECT TO OFF-SITE WATER QUALITY

摘要

This paper analyses the advantages and disadvantages of targeting soil conservation measures on the basis of off-site water quality goals. The Stratford Avon watershed in Perth County and the Big Creek watershed in Middlesex County, both located in southwestern Ontario, are used as case studies. Targeting criteria, used as proxies for measuring the contribution to off-farm damage from particular parcels of crop land, are based on the physical characteristics of the parcels. Alternative conservation tillage practices include fall chisel ploughing, ridge planting, no tillage and buffer strips.
