Almost two years after Cyclone Idai hit Mozambique, Zimbabwe, and Malawi, thousands of people remain displaced. At the time, Idai was the most powerful cyclone to hit the Southern Hemisphere in two decades, but it is no longer an anomaly. Worse, the Word Bank reports that climate change can potentially wipe out decades of social and economic progress in the developing world by displacing millions of people, many of whom will be pushed into poverty. Food and water insecurity connected to climate hazards—particularly in places dependent on agriculture—is a major factor which has forced families and whole communities to relocate for safety and subsistence.

“We produce more than enough food for the world’s population, but more and more people have been growing hungry in recent years,” said Kelly McFarland, Director of Programs and Research at the Institute for the Study of Diplomacy (ISD) at Georgetown University, during a panel discussion on COVID, Conflict, and Climate co-hosted by ISD and the Stimson Center’s Global Governance, Justice & Security, and Food Security Programs.

Environmental dimensions of armed conflicts

Years of armed conflict have devastated Yemen’s environment, contributing to one of the worst humanitarian crises in the world. Attacks on water infrastructure cut off thousands of people from access to safe drinking water, exacerbating a cholera outbreak that has caused an estimated 4,000 deaths since April 2017. Fighting also damaged Yemen’s agricultural infrastructure, contributing to the food insecurity of an estimated 16.2 million people.

It’s November in southeast Brazil, and the tall, feathery macaúba palms (Acrocomia aculeata) are beginning to drop ripe coconuts. By January, the ground is littered with them, as some 67 families that live nearby, outside the town of Jaboticatubas, get to work dragging the trove home.

This coconut serves as the lifeblood for these traditional farming communities in the Cerrado savanna in Minas Gerais state, Brazil. Archaeological sites trace its use back to at least 9,000 B.C.

Every part of the all-purpose coconut is used, from its delicious yellowish flesh to the nut at its core. It’s a favorite kids’ snack, and is used to make a highly nutritious flour, baked into bread and cookies. Livestock eat it too.

“For 30 years, a community of researchers, practitioners, and policymakers have been working to untangle the complex relationships between environmental change and human and national security, and find entry points for policies and programs that build on these connections to create a more resilient and sustainable peace,” said Lauren Risi, Project Director of the Wilson Center’s Environmental Change & Security Program at a recent event that featured contributors to a new special issue of International Affairs on environmental peacebuilding.

The travails of the last year, when a bat virus infected humans and turned the world upside down, were an unfortunate reminder of the inseparable ties between society and the natural environment.

So it is with water, which will again this year direct the course of history, through events small and large.

What are the large events to pay attention to? What are the trends and flashpoints?

Historically, Americans have not been entitled to adequate, nutritious food when they are hungry, at least not at the expense of federal or state governments. Public food assistance programs are and have always been limited and supplemental and not designed to cover all nutritional needs. The effects of limited government engagement with hunger have disproportionately affected women and people of color and resulted in a patchwork system of assistance where charities and privately funded food banks attempt to fill gaps left by the government’s Supplemental Nutrition Assistance Program (SNAP) program.

Globally, nearly 690 million people were hungry in 2019. Though the number of people who experience hunger in Asia has declined since 2015, the continent still accounts for more than half of the world’s hungry, or undernourished, at approximately 381 million people. Working toward Sustainable Development Goal 2 (SDG 2), “Zero Hunger,” will require major changes to the world’s food production systems.
