This paper has a threefold objective. First, it provides a comprehensive review of different approaches to analysing food security. Second, it highlights the added value provided by the capability approach and the human development paradigm. Third, it proposes a methodology to assess food security through this approach. Our proposal entails three basic steps: (1) analysis of food entitlements; (2) analysis of nutritional capabilities and (3) analysis of the capability to be food secure. In this way, we can move beyond income, entitlement or livelihood related frameworks, and identify the root causes of food insecurity. Food insecurity can be the result of a lack of education, health or other basic capabilities that constitute people's wellbeing. This, therefore, allows situating the study within the broader area of wellbeing and development

One of the World’s greatest challenges is to secure sufficient and healthy food for all, and to do so in an environmentally sustainable manner. This review explores the interrelationships of food, health, and environment, and their role in addressing chronic micronutrient deficiencies, also known as “hidden hunger”, affecting over two billion people worldwide. While the complexity and underlying determinants of undernutrition have been well-understood for decades, the scaling of food and nutrition system approaches that combine sustainable agriculture aimed at improved diet diversity and livelihoods have been limited in their development and implementation. However, an integrated system approach to reduce hidden hunger could potentially serve as a sustainable opportunity.

BACKGROUNDThe paper engages in the ongoing debate regarding the determinants of child nutrition in developing countries and stresses the potential contribution of the education of household members other than the child's parents. OBJECTIVEThe aim of the paper is threefold: (1) to verify whether there is evidence of the key role of parents' education for children's nutrition; (2) to explore the possible presence of the externalities generated by the literacy of household members different from the child's parents; (3) to test whether there is difference in the influence of these variables on the two indicators of child nutrition, child height-for-age and weight-for-age. METHODSThe determinants of child nutrition were analyzed by estimating a series of econometric models through OLS regressions applied on data from the 2003 DHS survey in Mozambique. By means of seemingly unrelated regression together with formal testing we compared the impact of the covariates on the two outcomes. RESULTSIn line with previous studies, we find that one year of mother's education increases their children's height-for-age and weight-for-age z-scores by nearly 0.025 and 0.015. The presence of another literate household member has a significant, though limited, effect on child height while it has no influence on child weight. Lastly, there is no statistically significant difference in the effect of parents' education on the two indicators while our measure of proximate literacy has a significantly larger impact on child height. CONCLUSIONSThese findings should orient policy-makers toward income-augmenting and educationenhancing policies: the importance of non-parents' literacy opens a further space for investment in education.
