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 Nuclear Balance Is What States Make of It

| Spring 2022

Recent quantitative scholarship uses warhead counts to examine whether nuclear superiority offers political or military benefits beyond having a secure second-strike capability. These analyses overlook other elements of a state’s nuclear capability such as state perceptions and beliefs.

A comparative analysis of the United States’ and the Soviet Union’s previously underexplored radiological weapons programs identifies the drivers behind their rise and demise. The findings of this analysis illuminate the factors likely to affect the pursuit of radiological weapons by other states in the future.

'What About China?' and the Threat to US–Russian Nuclear Arms Control

The administration of President Donald J. Trump has consistently used fear of China to undermine nearly five decades of bipartisan consensus on US–Russian nuclear arms control. The negative consequences of these actions may last far beyond the Trump presidency. If generations of agreement between Democrats and Republicans on bilateral nuclear treaties with Russia erode, it will pose a significant setback to US national security and global stability. Future leaders may ultimately need to consider new approaches to nuclear risk reduction that preserve the benefits of the arms control regime.

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

How the Next Nuclear Arms Race Will Be Different from the Last One

| 2019

All the world's nuclear-armed states (except for North Korea) have begun modernizing and upgrading their arsenals, leading many observers to predict that the world is entering a new nuclear arms race. While that outcome is not yet inevitable, it is likely, and if it happens, the new nuclear arms race will be different and more dangerous than the one we remember. More nuclear-armed countries in total, and three competing great powers rather than two, will make the competition more complex. Meanwhile, new non-nuclear weapon technologies — such as ballistic missile defense, anti-satellite weapons, and precision-strike missile technology — will make nuclear deterrence relationships that were once somewhat stable less so.

Seeds of Change: Calestous Juma died on December 15th

| Jan. 11, 2018

Colleagues said he tweeted more than any professor they knew, and Calestous Juma’s tweets covered a swarm of things. Income inequality, and a free-trade area for Africa, you might expect. Those were the subjects he taught at Harvard: getting poorer countries, especially in Africa, to grow and thrive was the obsession of his life. But he also tweeted about a wheelchair that could climb stairs, the increasing size of steaks, and the maximum number of goats seen eating up in a tree. He was extra-delighted to send out a New York Times editorial, from 1878, about Thomas Edison’s new “aerophone”: “Something ought to be done about Mr Edison, and there is a growing conviction that it had better be done with a hemp rope.”
