Go to the Arkansas Rice Festival in Wiener, Arkansas and you will discover how delicious – and diversely flavored – this cereal grain can be. Savory, sweet, or even spicy: Each dish at the festival’s annual rice recipe contest shows the many ways to prepare this international food staple.

Why look to Arkansas for rice? The state produces 4 million tons of it every year, which is nearly half the rice grown in the United States.  But that U.S. annual total is dwarfed by the amount produced by China, which at 207 million tons is the world’s largest rice producer.  It’s also natural that the world looks to China for rice; genomic mapping has suggested that cultivated rice was first grown in the Pearl River valley in southern China.

The Population Institute’s recent report, Invisible Threads: Addressing the root causes of migration from Guatemala by investing in women and girls, has brought attention to the numerous factors that drive migration in Guatemala. One of the key factors addressed in the report is climate change, which is linked closely to issues concerning land in that country. To this day, multiple generations of indigenous women endure the effects of land displacement and inequities in access to land—as well as related social and economic pressures. In concert with other political, social, and economic problems, this particular challenge has resulted in large outflows of migrants from the region.

Water sustains life on our planet. And access to clean and safe water is foundational to society. So why has it only been in recent years that water has risen to the top of discussions of climate and security? Richard W. Spinrad, the Under Secretary of Commerce for Oceans and Atmosphere and NOAA Administrator, says that one of the biggest reasons is the major impact that climate-related changes in precipitation like droughts and extreme rainfall are having across the globe: “We’re starting to see things like we’ve never seen before. The nature of storms is changing: We saw five feet of rain fall in Hurricane Harvey. Five feet.”

The world has plenty of reasons to avoid conflict already. Yet attendees at the recently-concluded COP27 climate conference in Sharm el-Sheikh, Egypt were presented with another compelling argument: Warfare is bad for global warming. So much so, in fact, that Ukraine’s delegation to the conference organized a special session at the conference of parties on “War Related Emissions,” bringing along a tree trunk bearing scars from Russian shell fragments as tangible evidence.

Is water important in climate policy? It seems obvious. Water has a well-established link as the medium of most negative climate impacts. Yet when it comes to addressing the climate crisis, the answer depends very much on who you ask.

As climate change is increasingly recognized as a security issue, a parallel understanding is also developing. Traditional categories and approaches may not be the optimal way to address the threats posed by climate impacts.

The nation states and international institutions at the center of security discussions now are shifting their approach. For instance, the U.S. has affirmed and moved to institutionalize its commitment to address the national security implications of climate change under the Biden Administration. In doing so, it is joining an increasing number of other nation-states (the UK, France, Sweden, Germany and New Zealand) that have also developed institutional arrangements and plans for their national response to climate insecurity.
