Food has long been used by countries to wage both war and peace, and the post-war era of American food dominance is no exception. Bryan McDonald, a professor at Pennsylvania State University, traces the United States’ “Food For Peace” strategy in his recent book, Food Power: The Rise and Fall of the Postwar American Food System, arguing that “food was central to national security” during this period.

According to a 2015 Georgetown University report on women and climate change, “the impacts of climate change – droughts, floods, extreme weather, increased incidence of disease, and growing food and water insecurity – disproportionately affect the world’s 1.3 billion poor, the majority of whom are women.”

Last month, a major multinational military exercise launched in South and Southeast Asia. The Pacific Partnership is the largest annual multilateral humanitarian assistance and disaster relief preparedness mission conducted in the Indo-Asia-Pacific and aims to enhance regional coordination in areas such as medical readiness and preparedness for manmade and natural disasters. At its center is the hospital ship USNS Mercy, with an international team of civilian and military specialists seeking to build response capacity in one of the most disaster-prone regions of the world.

The Lanjiang river in Eastern Zhejiang, China, reached its peak water level of 100 feet the night of June 25, 2017. Lanxi residents remember this day as “6.25,” marking the worst flood since 1955. Elsewhere in China that month, 7.3 million people were affected by floods, landslides, and heavy rains in northwestern Sichuan Province alone. Northern Guangxi suffered direct economic losses of 2.9 billion RMB (US$460 million). In the autonomous regions, 92,000 people were relocated. Flash floods caused the deaths of 10 people and forced 76,800 people to evacuate from Shanxi Province.

Natural bioshields—wetlands, forests, and urban green spaces—are critical tools for reducing the impacts of disasters on vulnerable communities. Between 1994 and 2014, nearly 7,000 natural disasters occurred worldwide, causing an average of almost 68,000 deaths each year. Climate change, growing populations, and widening economic inequality are all expected to increase the impacts of disasters. Bioshields—nature’s own solutions to natural hazards—can help protect people from these dangerous floods, storms, and heat waves.

“Floods are one of many factors that keep massive amounts of the population in poverty and always on the brink of disaster,” said Eric Viala at the second event in a four-part series on water security organized by the Wilson Center in cooperation with the Sustainable Water Partnership, which Viala directs. Panelists at the event discussed the impact of intense flooding on vulnerable communities and proposed innovative and collaborative approaches to reducing their risks in the face of disasters.

Without warning, water rushed into a woman’s home on a raised platform above the floodplain of Bangladesh’s Teesta River. She was just a hand’s distance from her infant son, but she couldn’t stop him from falling into the floodwaters. “She can’t recover back from the trauma,” said the University of Dundee’s Nandan Mukerjee of the mother who lost her child to the currents of climate change.

Hurricanes Irma and Maria devastated Puerto Rico, leaving many on the island without power, drinking water, or cellular service. Such disasters are not just an issue for the Caribbean, said the Wilson Center’s Roger-Mark De Souza in an interview with WOUB that was last month’s most read story on New Security Beat. All coastal areas of the United States, with their growing populations and vulnerable but valuable infrastructure, should be prepared to face more severe climate-related natural disasters.
