Around the globe, about 815 million people — 11 percent of the world’s population — went hungry in 2016, according to the latest data from the United Nations. This was the first increase in more than 15 years. Between 1990 and 2015, due largely to a set of sweeping initiatives by the global community, the proportion of undernourished people in the world was cut in half. In 2015, UN member countries adopted the Sustainable Development Goals, which doubled down on this success by setting out to end hunger entirely by 2030. But a recent UN report shows that, after years of decline, hunger is on the rise again. As evidenced by nonstop news coverage of floods, fires, refugees and violence, our planet has become a more unstable and less predictable place over the past few years. As these disasters compete for our attention, they make it harder for people in poor, marginalized and war-torn regions to access adequate food.

These choices are limited by lack of access to services, markets or credit; by poor governance or inappropriate policies; and by ethnic, gender and educational barriers. As a result, there is often little they can do to maintain secure or sustainable food production in the face of crises. Related: Drought doesn't cause famine. People do. The new UN report shows that to reduce and ultimately eliminate hunger, simply making agriculture more productive will not be enough. It also is essential to increase the options available to rural populations in an uncertain world. Conflict and climate change threaten rural livelihoods Around the world, social and political instability are on the rise. Since 2010, state-based conflict has increased by 60 percent and armed conflict within countries has increased by 125 percent. More than half of the food-insecure people identified in the UN report (489 million out of 815 million) live in countries with ongoing violence. More than three-quarters of the world’s chronically malnourished children (122 million of 155 million) live in
