A “Nuclear Umbrella” for Ukraine? Precedents and Possibilities for Postwar European Security

| Winter 2023/24

Europe after the Russo-Ukrainian War must develop a new security structure to defend against any Russian aggression. The safest option is a non-offensive, confidence-building defense. This option includes proposals such as the “spider in the web” strategy and the “porcupine” strategy to provide for European security in a region threatened by Russian expansion—without relying on the threat of nuclear war.

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.

Rather than revolutionizing war, drones demonstrate its evolution. The principle of air warfare remains avoiding exposure to the enemy. Drones are unlikely to shift the offense-defense balance toward the offense because they are vulnerable to attacks from the ground and air.

A Global Analysis of CO2 and Non-CO2 GHG Emissions Embodied in Trade with Belt and Road Initiative Countries

| 2020

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

| Jan. 03, 2019

During the Trump administration, the usual ways of conducting diplomacy have been upended. Many positions in the State Department have never been filled, and meetings with foreign leaders such as Kim Jong-un and Vladimir Putin have been undertaken with little advance planning.
