The UN's Sustainable Development Goal (SDG) for 'Zero Hunger' has refocused attention on hunger and malnutrition as major challenges for the 21st century and as essential desired goals for human development. This volume provides key insights on how these challenges for food security can be addressed globally and in a number of countries that face these challenges most acutely.

According to the World Food Summit, food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life. The implication is that lack of food security would overlap with hunger -- both overt and hidden -- and undernutrition and would have spillover effects onto the health of and labor market performance of those affected by such insecurity. This range of issues have guided the choice of contributions to this volume. Several manifestations of these topics are covered for a number of countries in Asia and Africa.
