| Lessons from integrated natural resource management (INRM) practiced at different scales are reviewed, with a focus on catchment management. INRM is complex, and many interactions have to be addressed. Consequently, the scale of investigation can restrict the generality and utility of the findings. Examples show that temporal, biophysical, and institutional scales can each be critical. Contexts and dynamics associated with particular scales, and interactions or lateral flows that become important with increasing scale, also pose serious challenges. A conceptual framework is presented for scaling issues in INRM and how to deal with them. To benefit many people over large areas within sensible time frames requires considerable political will, investment, and... |

| In this paper we argue that the loss of bio-diversity hould be of concern for farmers, though it seems to be of little or no concern to them at the moment. As diversity is a component of nature that controls the growth of pests, a loss of bio-diversity means increased exposure to pests, danger of crop failures and, in the long run, lower average yields and profits. So far farmers buy costly pesticides for compensating the reduction of bio-diversity. We argue that institutional problems are the reason why farmers are not concerned with bio-diversity, and show that under pure private property rights farmers have interest in pesticides and not in bio-diversity as a measure of crop protect because they have perhaps to devote land to the natural eco-system.
