This document is for all those who wish to support family farming, through national public policies in developing countries, and development aid and agricultural and trade policies in developed countries. It describes interventions that have helped remove some of the constraints to the development of family farming in specific contexts. These measures have a public policy dimension, either by directly implementing public policies or as project interventions that could potentially lead to public policies. The State is certainly a major actor in public policies, but all social and economic actors, especially family farmers themselves, should also participate in the formulation and implementation of public policies. Family farming can be supported through a whole range of public policies. This is a huge subject that we cannot hope cover exhaustively; and in any case, this paper is not intended to be a wish list of measures, but to show concrete cases of support for family farming that are particularly exemplary in terms of generating positive results in several domains (increasing production, securing more remunerative prices, etc.). Therefore, it considers various support measures that we believe to be essential. It is worth noting that this has been a complex exercise, given that ”success stories” in terms of public policies that have worked for family farming are fairly thin on the ground in developing countries.
