Climate security is an essential conceptual framework to understand the global interplay of biophysical and socioeconomic forces that threaten our planet. Indeed, it is so important that new currents of science, politics, and advocacy make refining definitions a necessity.

Seeing Loreta sort and dry her Omena sardines at the shores of Lake Victoria in Western Kenya, one may dismiss this small, middle-aged woman as an ordinary fishmonger struggling to earn a living.

The negative impacts on global food security wrought by Russia’s war in Ukraine are obvious. But recent news that Russia currently occupies more than one fifth of Ukrainian farmland, draws attention to another dimension of this politically-induced food and agricultural crisis: land itself. Of course, territory has long been an object of conflict and warfare. But agricultural land—in particular—is also a key, though understated, dimension of the geopolitical ambitions undergirding Russian activity at home and abroad.

The much-needed transition to a zero carbon, green economy offers opportunities to contribute to peace, but only if the conflict risks of transition are understood and managed to produce a just and peaceful transition. That means minimizing “backdraft”—the unintended negative impacts of transition that are a key obstacle to that goal.

Of COVID-19’s many lessons, one is most critical to our collective next steps:

Business as usual in global health is no longer possible.

The pandemic exposed weaknesses in health systems across the world, and particularly in the delivery of equitable, high-quality reproductive, maternal, newborn, adolescent, and child health (RMNCAH) services. It also reinforced that effectively addressing these challenges requires rapid, responsive approaches driven and owned by countries and local institutions.

While the world’s population now approaches 8 billion people, global fertility rates have been declining for decades. The overall drivers of this decline include increased access to contraception and reproductive health care, an increase in women seeking higher education, women’s empowerment in the workforce, lower rates of child mortality globally, increased cost of raising children, and overall greater gender equality.

When Russia struck a deal with Ukraine on July 15, there was hope that millions of tons of food would once again be able to flow from the embattled country. Under the agreement, brokered by Turkey and the UN, Russia would lift naval blockades and allow large-scale shipments of grain to leave Ukraine’s ports.
