A rating for the potential impact, the residual impact and the risk is also provided. Good practice mitigation measures are described in the environmental management section below. The major potential impacts associated with the agricultural enterprise categories include water and air quality deterioration, loss of biodiversity and impacts on biophysical resources, including vegetation cover losses and soil erosion. Most of the benefits presented in the are socioeconomic. The only biophysical benefit (or environmental enhancement) is the storage of agricultural chemicals (including fuel). However, it is the biophysical resource base that supports much of the rural economic activity (e.g. soil, water, forests, and mineral resources). Table 3.
