A Portfolio of Effective Water and Soil Conservation Practices for Arable Production Systems in Europe and North Africa

To secure sustainable food production for meeting the growing global demand for food, it is imperative, while at the same time challenging, to make efficient use of natural resources with minimal impact on the environment. The study objective is to provide insights into the multiple benefits and trade-offs of different sustainable agricultural practices that are relevant across pedo-climatic zones in Europe and North Africa, including conservation agriculture, crop diversification, organic agriculture, and agroforestry. Widespread adoption of these practices in specific regions depends on the effectiveness with which their applications and attributes are communicated to farmers, and their suitability to local conditions and opportunities. Scale impacts of the practices range from field to catchment levels, but the best empirical evidence has been generated at field level in on-farm and experimental trials. The outcomes from the application of each of these practices depend on variables specific to each site, including pedo-climatic zone, geography, weather, ecology, culture, and traditions. Each practice has trade-offs and the same practice can have different effects when compared to conventional agriculture. To make site-specific recommendations, a careful assessment of overall benefits must be made. Adoption can be stimulated when farmers have the opportunity to experiment on their own land and discover the advantages and disadvantages of different practices.
