Abstract
ABSTRACT An ethnoecological study was carried out in the Purhepecha community of San Francisco Pichataro, west central Mexico, with the purpose of investigating how land degradation, in terms of soil erosion and fertility depletion, was (and still is) handled by indigenous farmers so that traditional agriculture could remain sustainable over centuries. After briefly reviewing opposite views on the land degradation issue in the regional context of the Patzcuaro lake basin, the paper focuses on land management at local level. The indigenous concept of land is discussed as an integrated whole, including water cycle, climate, relief and soils. Indigenous people venerate land as the mother of all living beings, including humans. Therefore, people's health and survival require good land care and management. Local knowledge on land management is organized around four basic principles: land position, land behaviour, land resilience and land quality. Fanners recognize land as a dynamic subject, a concept reflected in the expression ‘land moves and behaves’. Soil erosion and fertility depletion are perceived as ‘normal’ processes the farmers control by means of integrated management practices. Farmers recognize several land classes, primarily controlled by landscape position, which require different land care. The example of San Francisco Pichataro demonstrates that traditional agriculture does not necessarily lead to land degradation. But the collective knowledge, or social theory, on land management is increasingly exposed to be fragmented as the community undergoes structural changes and loses its social cohesion under the pressure of externalities such as off‐farm activities, out‐migrations and governmental intervention, among others.
