ColdHubs, an innovative Nigerian agricultural enterprise that uses solar-powered refrigerated storage units to keep food from spoiling, is slowly but surely expanding to nearby West African countries. But it faces big challenges to scale up and finance its operations, company founder and CEO Nnaemeka Ikegwuonu told a Harvard Kennedy School audience celebrating the 2022 Roy Award winner.

Meghan M. Garrity, an International Security Program postdoctoral fellow at the Harvard Kennedy School's Belfer Center discussed her research on government-sanctioned mass expulsion events at a virtual seminar on November 3, 2022.

Climate change, especially the variability of rainfall patterns, poses a threat to maize production in Ghana. Some farmers harvest rainwater and store it for maize production to cope with unpredicted rainfall patterns. However, there are only a few studies on the adoption of rainwater harvesting for maize production. This study analyses the factors that influence farmers' decision to harvest rainwater for maize production in Ghana. 

The Environment and Natural Resources Program at Harvard Kennedy School’s Belfer Center for Science and International Affairs announced today that ColdHubs Limited is the winner of the 2022 Roy Family Award for Environmental Partnership. The company—born out of a partnership between the Smallholders Foundation, the Institute for Air Handling and Refrigeration (ILK Dresden), and the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ)—uses solar-powered walk-in cold rooms to reduce post-harvest losses for smallholder farmers across rural Nigeria.

According to the U.N. High Commissioner for Refugees, at the end of 2021 nearly 90 million people were forcibly displaced worldwide. What makes Uganda's expulsion of 50,000 Asians distinct? Unlike most displaced people, the Asians expelled from Uganda weren't fleeing conflict or natural disasters. Instead, the forced displacement that year is what political scientists call a mass expulsion. That's when a government implements an ethnically targeted policy to remove a group of people, en masse, without individual legal evaluations and refuses to allow them to return.

Kelly Greenhill argues that by exploiting political divisions that exist within targeted states, the threatened or actual deployment of engineered flows of migrants has long been a distressingly effective policy instrument, and it is unlikely to go away anytime soon. Unless policymakers begin to confront the forces that enable weaponized migration, the favored policy responses seem destined to increase, rather than curtail, its use.

The geopolitical and geo-economic forces wrought by the coronavirus pandemic, as examined previously in this series, are likely to slow the transition to a more sustainable global energy mix. Fortunately, the pandemic has also resulted in governments gaining vastly greater influence over whether this shift stalls or accelerates.

For most people, there was nothing to celebrate when the International Monetary Fund downgraded its outlook for global economic growth in June, anticipating a contraction of 4.9% for 2020. Yet for others, such as the small but persistent group of economists and others known as the “degrowth movement,” the Covid-induced economic slowdown has a silver lining.

The search for silver linings to the coronavirus pandemic has come up woefully short. But one hopeful — and much talked of — prospect is that the disruption will accelerate the global shift to a more sustainable energy future.

The Belt and Road Initiative (BRI) is an important cooperative framework that increasingly affects the global economy, trade, and emission patterns. However, most existing studies pay insufficient attention to consumption-based emissions, embodied emissions, and non-CO2 greenhouse gases (GHGs). This study constructs a GHG emissions database to study the trends and variations in production-based, consumption-based, and embodied emissions associated with BRI countries
