Environmental impact assessments of agricultural practices on a regional scale may be computed by running spatially distributed biophysical models using mapped input data on agricultural practices. In cases of hydrological impact assessments, such as herbicide pollution through runoff , methods for generating these data over the entire water resource(More)
Many farming-system studies have investigated the design and evaluation of crop-management practices with respect to economic performance and reduction in environmental impacts. In contrast, little research has been devoted to analysing these practices in terms of matching the recurrent context-dependent demand for resources (labour in particular) with(More)
On a regional scale, many management concerns, such as agricultural planning and water contamination management, require information regarding the diversity and location of agricultural practices. One means of obtaining this information is to search for spatially explicit indicators that correspond to factors that drive agricultural practices. The objective(More)
