While a sectoral approach to FSN policy and strategy is necessary, it is not a sufficient condition to impact rural livelihoods and reduce inequalities (between rural and urban areas, across rural areas or across individuals). In addition to the availability dimension, there is a need to address the issues of access to food (both economic and physical), the nutritional quality of food (utilisation), and the stability of both the availability and access dimensions in the long run. Other causes of food insecurity' are generally attributed to low incomes, unemployment, health, education, nutrition status, natural resource degradation and weak political commitment, which exacerbate vulnerability to risk. As noted by the FAO, fighting rural poverty and food insecurity will require resilient and diversified rural economies that offer employment and income opportunities. Helping small farmers improve farm productivity can help, but in most contexts, it is not enough to lift all rural poor out of poverty (FAO, 2013).
