Summary of Concept 

Rationale for Prioritizing Food & Nutrition Security

We are witnessing multiple burdens of malnutrition, with some countries, communities and households suffering from combinations of undernutrition, overweight and obesity, and micronutrient deficiencies. Grappling with these multiple burdens of malnutrition are deeply tied to political, social and economic factors.

There are currently 784 million people who are undernourished, 159 million children under five who are chronically undernourished or stunted, 50 million children under five who are acutely malnourished or wasted, and 2 billion and 1.2 billion people who are estimated to be iron and zinc deficient respectively (FAO 2015; UNICEF/WHO 2015; Black et al 2013). Although child mortality and undernutrition is slowly declining, it is unclear if these trends will remain with significant external drivers that will challenge us – climate change, population pressure, persistent social inequalities, and geopolitical conflict.  Current estimates on climate change, for example, are expected to have dramatic impacts on crop yields, notably in South America, Africa, and South Asia, while also leading to greater food price volatility that are likely to have their greatest impact on the poor (Havlik et al 2015).

Who are we serving?

Over one billion people live in extreme poverty, earning less than $1.25 a day (Chen and Ravallion, 2008), while more than two-thirds of these extremely poor people go hungry (FAO, 2012). In the past, poverty was associated with severe forms of acute undernutrition, particularly in children, that were frequently seen in times of famine and hunger. Today, we know that poverty affects nutrition throughout the whole life-span and has a broad spectrum of manifestations, such as increased propensity to many diseases, both infectious and non-communicable, reduced physical work capacity, a lower learning and intellectual capacity, increased exposure and vulnerability to lifestyle-related and environmental risks, reduced participation in social decisions, and negligible capacity of resolution in the face of environmental challenges (Peña and Bacallao, 2002). This lack of food and poor nutrition impacts a person’s ability to earn a living, creating a vicious cycle of poverty and malnutrition. Individuals lose 10% of their potential lifetime earnings, and countries lose 2-3% of their GDP due to undernutrition (World Bank, 2006).

All forms of malnutrition are the result of interactions between poor diets, unhealthy food systems and inadequate health services. Food systems govern the types of food produced and their journey from farm to fork. As populations urbanize, incomes increase and the food industry concentrates and globalizes, the food system struggles to produce healthy food for everyone. The failure to identify and implement actions to make food systems healthier is costly. The human health consequences of malnutrition is detrimental: 45 percent of all under five mortality results from malnutrition and the multiple burdens of malnutrition represent tone of the biggest drivers of global burden of disease, with low-quality diets being the number one risk factor for global disease burdens. Despite the centrality of food quantity and quality as determinants of nutrition adequacy and the fundamental importance of food systems in determining which foods are available, affordable and acceptable, the multiple opportunities to intervene in food systems to promote nutrition are not well known, understood or addressed. This is because both food systems and malnutrition burdens are complex and context-specific, making it difficult to identify the links between them and the actions needed to leverage those links (High Level Panel of Experts on Food Security and Nutrition 2016)
