Between aspirations and reality Making farming, food systems and rural areas more resilient, sustainable and equitable

Despite a longstanding literature on small farm-households, there is limited consideration of small farms' role in food and nutrition security (FNS) at territorial level. The purpose of this study is to provide insights about how small farms contribute to FNS at different territorial scales, by focusing on farmers' strategies and consequential FNS outcomes. Analysis is based on two years (2017-2019) of field work done with farmers and food system actors in SALSA reference regions culminating in a workshop done with research partners. We find that small farms deliver food and nutrition security and other socioeconomic and environmental outcomes for the farmhousehold, at local, regional and global levels. The regional level is shown to be critical for small farms, as it provides the scale at which their diversity is realised. Understanding this diversity is a goal for both research and for effective support mechanisms for small farm integration, and the multiple public and private functions small farms can deliver should be higher on the policy agenda.

Abstract. Leaching losses of nitrate‐nitrogen were measured from a set of eight hydrologically isolated plots on a clay loam soil over the period from September 1987 to February 1990. Variable drainflow recovery from the plots hampered accurate estimation of nitrate loading, but results suggest that, when inorganic nitrogen fertilizer is applied up to the recommended amount, there is little influence of the amount applied on the amount leached. We did, however, observe the following effects on nitrate leaching: leguminous green manure incorporated in autumn increased leaching of nitrate‐nitrogen by 10–15 kg per hectare during the winter; autumn cultivation caused some increase in leaching compared with no cultivation in one year; some systematic variations in nitrate leaching occurred between years and between plots, but were unrelated to treatments. From the results we conclude that green manuring does not provide sufficient nitrogen for organically grown crops on this soil but contributes significantly to nitrate leaching, and that growing spring cereals, with the land remaining in stubble as long as possible in autumn, may be the best strategy to minimize nitrate leaching.
