This letter reviews the scientific literature on whether and how environmental changes affect the risk of violent conflict. The available evidence from qualitative case studies indicates that environmental stress can contribute to violent conflict in some specific cases. Results from...

This article reviews the existing theoretical arguments and empirical findings linking renewable and non-renewable natural resources to the onset, intensity, and duration of intrastate as well as interstate armed conflict. Renewable resources are supposedly connected to conflict via scarcity,...

Civil society is commonly assumed to have a positive effect on international cooperation. This paper sheds light on one important facet of this assumption: we examine the impact of environmental non-governmental organizations (ENGOs) on ratification behavior of countries vis-à-vis international...

Valid and reliable measurement of countries' climate policy performance is important both for policy-making and analytical purposes. The authors contribute to this end by introducing a new dataset that offers such information for up to 172 countries for the time period 1996–2008. Their Climate...

Several studies examining implications of the modern welfare state arrive at rather positive conclusions: generally, they find that economically “kinder, gentler societies”, that is, countries providing stronger state-sponsored social-safety nets for their people, perform better on various...

A recent Climatic Change review article reports a remarkable convergence of scientific evidence for a link between climatic events and violent intergroup conflict, thus departing markedly from other contemporary assessments of the empirical literature. This commentary revisits the review in...

This article focuses on one of the most likely empirical manifestations of the “environment-conflict” claim by examining how demand for and supply of water may lead to domestic water conflict. It also studies what factors may reduce the risk of conflict and, hence, induce cooperation. To...

Hydro-political dependencies between countries are widely regarded as having important implications for international water cooperation and conflict. Quantitative ex-post empirical research on the subject so far uses very simple characterizations of international river geography to proxy for...
