Farm dependency to inputs is an issue concerning both farms and society. Viticulture is an input-intensive sector of agriculture. Some innovations in agriculture have been designed to reduce the use of inputs, such as fungi-resistant vine varieties. As the diffusion of innovation is uneven, we will compare the characteristics of innovations in both sides of the upper Rhine River. In this way we will interview farmers and analyze the geographical context. We will also comare the farms characteristics and their contexts at various scales. We expect to get a typology of innovations, wtih characteristics such as the impact on various scales (e.g. cropping system, farming system) and the radicalness of the changes. We also expect to get some information about the eventual levers and incentives to innovations' diffusion, adoption or abandonment. And finally, French and German innovations will be compared to others vineyards innovations. It is possible to sharply describe several innovations reducing vineyard inputs, located on both sides of Upper Rhine River.
