Jordan is facing a deepening, multi-faceted freshwater crisis. Climate change and population growth are exacerbating its extremely limited natural water availability and dependence on transboundary rivers and groundwater. Water-poor and functionally landlocked, Jordan serves as an archetype of a water-stressed nation.

In January, President Biden joined other world leaders in committing to conserve 30 percent of their nations’ lands and oceans by 2030. Also known as “30 by 30,” the pledge aligns government action with the growing recognition by the intelligence community that the loss of ecosystems and biodiversity presents serious risks to the U.S. economy and national security. Risks to the U.S. include the expanded likelihood of wildlife-borne diseases spilling over into our communities, water system challenges, decreased crop production, and increased natural disasters like floods. 

Joyce Makasi, a young woman in Kambiti village, Kitui County, Kenya, went into labor with her second child one afternoon in December 2020. She had just enough money to hire a motorbike to take her to nearby Waita health center. At the facility, the clinical officer and nurse told her she would need a cesarean delivery. It wouldn’t be her first cesarean, but COVID-19 presented new obstacles.

The Huangzhong district in Xining city, the capital of Qinghai Province, is home to 8,980 families, all of whom received assistance under China’s national policy to eradicate extreme poverty (below 2,300 yuan per person per year). Through social assistance and private sector financing, Huangzhong district succeeded in lifting all 28,706 residents out of extreme poverty after a four-year battle. In April 2019 the district proudly celebrated its official removal of the “poverty alleviation county” label. 

Do you remember a year ago when many of us traveled regularly? Do you remember the experience of flying into a major city somewhere in the world, picking up your bags in a modern airport (that probably functioned more efficiently than in the United States), and getting a vehicle to take you downtown? After leaving the airport, we would often drive past miles of informal settlements—self-built shelters unkindly called “slums” much of the time. We may have even found ourselves asking why local authorities “don’t do something” about them.

Waste banks are a cornerstone of Indonesia’s waste reduction efforts. Seeking to prevent plastic waste from getting burned or choking waterways, communities establish these places for people to bring plastic waste to be recycled. It only took a few months to see tangible results at the Bumi Daya Bersih waste bank in West Jakarta. In addition to collecting and sorting waste, the waste bank community is also contributing to waste prevention. A number of regular waste bank customers have started bringing empty plastic packaging that’s not intended to be recycled (yet) but instead refilled with high-quality home and body care products.

That future wars will be fought over water, rather than oil, has become something of a truism, particularly with regard to the Middle East. It’s also one that most water experts have refuted time and time and time again. But while this preference for cooperation over conflict may (and emphasis on may) remain true of interstate disputes, this blanket aversion to the ‘water wars’ narrative fails to account for the rash of other water-related hostilities that are erupting across many of the world’s drylands. As neither full-on warfare nor issues that necessarily resonate beyond specific, sometimes isolated areas, these ‘grey zone’ clashes don’t seem to be fully registering in the broader discussion of water conflicts. In failing to adequately account for the volume of localized violence, the world is probably chronically underestimating the extent to which water insecurity is already contributing to conflict.

The last decade was the warmest on record, with 2020 tied with 2016 for the all-time high average annual global temperature. This 10-year period also saw armed conflicts at severity levels not seen since the Cold War era. Could there be a causal link between these trends?

To the frustration of policymakers and laymen alike, empirical research has been unable to provide a simple and coherent answer to this question. Instead, studies of climate-conflict connections have for a long time continued to produce diverging findings and – occasionally – inspired heated debates. So, where do we stand?

In a review article introducing a new special issue of the Journal of Peace Research (JPR) on the security implications of climate change, we assess the nature and extent of scientific progress in climate-conflict research over the past decade. As yardsticks for measuring progress, we identify seven key research priorities frequently advocated in earlier reviews of the quantitative literature.
