The determinants of local collective action on erosive runoff. An analysis of farmers' geographical proximities in Upper Normandy, France
Runoff disregards territorial boundaries, affects farmers as well as other users of space, and necessitates collective action if it is to be combatted. In this article, based on the case of Upper-Normandy, we show that geographical proximity can play a determining role in the struggle against erosive runoff, and we present a new tool for analysing relations of proximity between farmers. First, we ...
