Description:
Soil erosion has conventionally been perceived as the chief cause of land degradation, yet the limited effectiveness and poor uptake of widely promoted physical and biological anti-erosion methods challenges this logic. An alternative perception focusing on prior land damage - notably to soil cover, architecture and fertility - permits an holistic, farmer-centred approach which has generated positive response to date.
