Simply put, without water there is no food. Global food and nutritional security require resilient agricultural systems, which, in turn, depend on reliable and sustainable supplies of freshwater, whether from rainfall or irrigation. It is an often-neglected dependency, and one that threatens to undermine our ability to meet our future food needs and maintain the ecosystems upon which all life depends.

Climate change will upend the 21^st century world order. It will redefine how we live and work, and change the systems of production, trade, economics, and finance. Even now, in the midst of a global pandemic, it is clear that climate change will be the defining issue of this century. In fact, COVID-19 has only underscored the inadequacy of our responses to global crises and heightened the urgency of this call to action. 21^st century diplomacy will have to raise climate ambition, shape the transformative systems change needed, and promote and facilitate new modes of multilateral collaboration.

“As we face a global pandemic that has taken the lives of more than 800,000 people as of right now around the world, we certainly have to recognize the particular impacts that that has had on women and girls and their lives,” said Rep. Chrissy Houlahan (D-PA), at a recent event hosted by CARE and UNFPA about the global impact of COVID-19 on women and girls. While women make up 70-80 percent of frontline healthcare workers globally, they have also been disproportionately affected during the pandemic by increased rates of gender-based violence, lack of access to sexual and reproductive healthcare, and economic and food insecurity.

A quiet disruption to the established financial order is underway: Around the world, institutions are pulling their investments out of fossil fuels. Climate activists campaigning for divestment suggest that such economic rearrangements might keep oil, gas, and coal in the ground, curbing carbon emissions. In parallel, some high-profile advocates call for reinvestment in renewable energy. But can the financial sector really drive the structural changes needed to address climate change—and, more fundamentally, climate justice? 

Our collective development objectives will not be achieved if they come at the expense of biodiversity and natural resource management, said Jeff Haeni, Acting Deputy Assistant Administrator in the Bureau for Economic Growth, Education, and Environment at USAID. He spoke at a recent Wilson Center virtual event, co-hosted with USAID, that explored the links between conservation and public health with examples from USAID’s BRIDGE project, which aims to build the evidence base for integrating biodiversity conservation considerations into policy discussions and decision-making across sectors. “The ability of societies around the world to develop and thrive is dependent on the health of the forests, fisheries, and natural systems around them,” he said.

Weeks before most of the world began to take the spread of COVID-19 seriously, Africa was already threatened by another plague, the biggest locust outbreak in the last 70 years. Locusts swarmed into Ethiopia, Kenya, Somalia, Uganda, and South Sudan in January and February this year. Those hordes of voracious locusts laid eggs, and now the second wave, 20 times the size of the first group, is arriving. According to Locust Watch, “The current situation in East Africa remains extremely alarming as more swarms form and mature in northern and central Kenya, southern Ethiopia, and probably in Somalia.”

As the humanitarian community responds to the Covid-19 pandemic, other long-term pressing priorities persist and require innovative solutions. The dry zone which extends across Central America encompassing parts of Guatemala, Honduras, El Salvador, and Nicaragua and a 10-year drought has left 1.4 million people in urgent need of food assistance. The impact of climate change, which includes extreme drought, poses an ever-increasing risk across Central America and contributes not only to food insecurity but also to migration issues that have plagued the continent in recent years.

A special type of tree could facilitate peacebuilding in the Sahel. A stretch of semi-arid land south of the Sahara that runs from the Red Sea to the Atlantic Ocean through 10 countries (Eritrea, Sudan, Chad, Niger, Nigeria, Burkina Faso, Mali, Algeria, Mauritania, and Senegal). But the western subregion covering the Lake Chad area (the intersection of Chad, Cameroon, Nigeria, and Niger) and Liptako-Gourma (the tri-border zone of Burkina Faso, Mali, and Niger) in the Sahel has been the scene of a growing humanitarian crisis. Armed groups are terrorizing local populations. Rampant insecurity has forced 1 million people to flee their homes. People have been cut off from their livelihoods. Food insecurity is worsening. Casualties continue to mount. And climate change will likely exacerbate conditions, forcing more people to compete for depleted forest resources and land. More food shortages and instability will surely follow.
