The Global Food Security Index, a gauge of how accessible food is around the world, found this month that most countries are becoming more food secure, even as they face long-term and new challenges to getting enough nutrition.

The 2016 report, released earlier this month, found that 89 of the 113 countries in the index have experienced food-security improvements over the past five years, mostly as a result of a better global economy and lower food costs.

Weather and climate change-related risks, as well as market-distorting government food policies, pose risks to food prices and food availability in the future. The report noted that developing economies that prioritize investment in agricultural storage and transport infrastructure increase their capacity to feed growing populations.

Sub-Saharan Africa lags behind other regions in agricultural infrastructure, the report found. Storage capacity across the region has improved, but road and port infrastructure is poor.

The Global Food Security Index is sponsored by DuPont, but the Economist Intelligence Unit (the same group that publishes The Economist magazine) exercises full and final editorial control over all content, including data gathering, analysis and forecasting.
