Livestock systems and land use: which diversity for which sustainability?

Abstract : Changes in agriculture during the twentieth century led to high levels of food production based on increasing inputs and specialization of farms and agricultural regions. To address negative externalities of these changes, two forms of ecological modernization (EM) of agriculture are promoted: “weak-EM”, based on increasing input efficiency through crop and animal monitoring and nutrient recycling, and “strong-EM”, based on increasing agrobiodiversity at different space and time scales to develop ecosystem services and in turn reduce inputs. We analyze whether within- or among-farm diversity (in species or farming practices) is an asset for the sustainability of livestock systems. First, we propose a multi-scale (field to territory) and multi-domain (environmental, economic, social) analytical framework for defining local livestock systems at stake in our analysis, then we describe its forms of EM (weak vs. strong). Second, we assess both systems, considering sustainability as a state described by state variables and as a process assessed according to ecological (e.g. diversity) and socio-economic principles (e.g. economy of scale or scope, agricultural innovation system type). We analyze their resilience in the face of a changing environment. Third, we apply our framework to assess a variety of livestock system case studies (dairy, organic, integrated crop-livestock).
