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.

“It is often expected that women care more, and therefore women are going to volunteer, and be the saviors” in times of crisis, said Eleanor Blomstrom, the Program Director and Head of Office for the Women’s Environment & Development Organization (WEDO), at a Wilson Center event on climate displacement and the changing role of women. A panel of experts discussed the impacts of climate change that not only force women to move, but also put them disproportionately at risk.  By integrating gender dimensions of climate-related displacement into research, policy, and programs, we can gain a better understanding of the challenges that women face and support women’s efforts to be changemakers for their communities as they adapt to climate threats. “All issues are women’s issues,” said Blomstrom.

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.

“Climate is unquestionably linked to armed conflict,” said Halvard Buhaug, a professor at the Peace Research Institute Oslo and the Norwegian University of Science and Technology, at a recent Wilson Center event marking the end of the three-year Climate Anomalies and Violent Environments (CAVE) research project. But, he stresses that under a changing climate, exactly how and through what pathways is still a subject of much debate in the academic community.

In 2014, we met with some of the technical leads of a major Chinese river basin authority in Beijing and asked them whether they were more worried about pollution or climate change impacts. Both, the engineers replied. Pollution affects us every day, they said, but changes in the climate erode our ability to supply drinking and irrigation water, manage floods, and generate electricity.

China must address its environmental and climate change challenges, such as reducing water pollution and building resilience to droughts, floods, and long-term climate shifts. But existing sources of finance have not met the growing demand for environmental projects.

Cape Town is running dry. But thanks to its sophisticated water management efforts, the city may ride out the crisis. However, other cities that lack these capacities are less likely to survive Day Zero. Especially in developing countries, where urban water services are often provided by informal or illegal actors, running out of water could have dangerous ripple effects for peace and security.
