“Save your kitchen scraps to feed the hens,” urged a poster for the victory gardens created on the home front in the Second World War. Feeding food scraps to backyard chickens and pigs turned this waste into a delicious source of human food. Pigs were especially prized in this effort as they would eat what most other animals considered inedible.

At a recent Brookings Institution event titled Climate Change, Food Insecurity, and Migration in the Middle East, Ferid Belhaj, Vice President for the Middle East and North Africa (MENA) at the World Bank, observed that the MENA region relies heavily on grain exported from both Ukraine and Russia. When the 2022 invasion reduced grain exports to a trickle, the entire region suffered heavily.

A new initiative by the Climate Action Reserve, a nonprofit organization based in Los Angeles, could play a significant role in curbing emissions of a potent climate pollutant from chemical plants in China while filling a gap in international climate agreements and China’s environmental regulations. 

Nigeria is home to many violent conflicts, one of which is the farmers-herders conflict that has posed severe security challenges in the country. The human toll of the violence has been immense, claiming more lives than the Boko Haram insurgency. Hundreds of thousands of people have been killed or displaced. Nigeria has also experienced increased ethnic, regional, and religious polarization, and this crisis has undermined national stability and unity.

The idea of climate change as a “threat multiplier” has been gaining steam since it was first proposed roughly 15 years ago. This framing acknowledges that climate can interact with existing political, social, and demographic conditions to heighten communities’ security risks—which in turn suggests that problem-solving in the face of these risks must be interdisciplinary.

The United Nations Population Fund (UNFPA) 2023 State of the World Population (SWOP) Report offers a chance to reflect on what’s at stake in debates over global population. “The question is not whether the human population is too large or too small. The question is whether everyone can exercise their fundamental human right to choose the number and spacing of their children,” said Sarah Craven, Chief of the Washington Office of UNFPA at the virtual D.C. launch of the report at the Wilson Center on April 26, 2023.  

As international cooperation to mitigate climate change gathers pace, most European nations have adopted strategies to decarbonize their economies. It is a signal that these countries recognize the need to reduce the concentration of carbon dioxide in the atmosphere in order to limit global warming to 1.5 degrees Celsius above pre-industrial levels.

The increase in global temperatures by over 1 degree Celsius since preindustrial times is already having broad and significant impacts. An ongoing multi-year drought in Eastern Africa, for instance, has been attributed to global warming. Hunger crises, displacement, and exacerbated conflict between pastoralist groups are some of the reported dire consequences.
