About the Paper

This paper presents news ways to track violent conflict over time, providing conflict barometers for interstate and civil conflict, respectively. After critiquing previous efforts at measurement, the authors discuss general principles concerning the utility of conflict barometers. The interstate barometer is based on establishing a baseline for the relationship between a pair of states and then using the incidence and severity of militarized confrontations to track variations around those baselines. The resulting Interstate Conflict Severity Barometer (ICSB) is scaled from 0 (no violent conflict) to 1,000 (rivalry plus severe militarized confrontations) for 2,631 different state-state relationships over the period 1900–2015. Data are available in the form of monthly conflict barometer scores for those pairs of states, and there are over 1 million observations in the data. Short narratives are matched with barometer scores for five illustrative cases: India-Pakistan, Israel-Egypt, France-Germany, US-China, and Ecuador-Peru. The Civil Conflict Barometer (CCB) is built on a combination of armed violence deaths, military coups, and substantial human rights violations. Ranging from 0 (high-quality negative peace) to 1,000 (serious and widespread violent conflict), the CCB covers 79 different countries at risk for conflict over the period 1989–2019. Data are available on a yearly basis for these countries, and there are 2,432 individual data points. Short narratives are matched with barometer scores for three illustrative cases: Haiti, Venezuela, and Mozambique.

China, Philippines Have Big Disagreements Over Their Recent Deal

Thursday, July 25, 2024

China and the Philippines this weekend reached a deal aimed at reducing their growing tensions over Second Thomas Shoal. The agreement comes as maritime confrontations have been increasing in frequency and intensity, raising fears of a broader conflict that could lead to the Philippines invoking its mutual defense treaty with the United States. While the deal could be a key step to reducing tensions, messaging from both Beijing and Manila suggests that both sides still firmly maintain their positions on the disputed waters, and that they see the agreement’s provisions in fundamentally different ways.

What the Houthi-Israel Exchange Might Mean for Escalation in the Middle East

What the Houthi-Israel Exchange Might Mean for Escalation in the Middle East

Wednesday, July 24, 2024

The Middle East saw yet another escalatory episode over the weekend, as Israel and Yemen’s Houthis exchanged fire. On July 19, the Iran-backed Houthis launched an unprecedented drone attack on Israel, which hit an apartment building in downtown Tel Aviv, killing one and injuring at least 10 others. It was the first time that the Houthis killed or even harmed an Israeli, despite launching dozens of missile attacks on Israel since October 7. The next day, Israel struck back with an airstrike on the strategic port of Hodeida, marking the first time it attacked Yemen. The Israeli attack killed six, injured dozens more and left ablaze key oil facilities in the area.

The Red Sea Crisis Goes Beyond the Houthis

The Red Sea Crisis Goes Beyond the Houthis

Friday, July 19, 2024

The Red Sea is in crisis. At the center of the storm are Yemen’s Houthi rebels, who have unleashed a wave of attacks on ships traversing one of the world’s most pivotal maritime straits, putatively in support of Hamas’s war against Israel. The Houthi gambit in the Red Sea is imposing serious costs on global trade, as did the problem of Somali piracy, which reached its peak in 2010. The United States and some of its allies have stepped in to militarily suppress the threat, bombing Houthi positions inside Yemen. But although this episode is illustrative of the difficulties of Red Sea security, the crisis extends far beyond the trouble emanating from Yemen.

Putting Data Around Intergroup Violence and Sorcery Accusation–Related Violence in Papua New Guinea

Putting Data Around Intergroup Violence and Sorcery Accusation–Related Violence in Papua New Guinea

Tuesday, July 2, 2024

This discussion paper provides analysis of newspaper reports from Papua New Guinea around two different but interconnected forms of violence: intergroup violence and sorcery accusation–related violence. The authors conclude that both types of violence are fueled by money politics, the widespread availability of guns and the normalization of violence, the erosion of traditional and local forms of leadership and regulation, and public service delivery failures.
