TL;DR: In the period 1946-2001, there were 225 armed conflicts and 34 of them were active in all of or part of 2001 as mentioned in this paper, and this dataset has now been backdated to the end of World War II.

TL;DR: In this article, the distinction between combatant deaths, battle deaths, and war deaths is made and a new dataset of battle deaths in armed conflict is presented for the period 1946-2002, mainly due to a decline in interstate and internationalised civil armed conflict.

TL;DR: In this paper, the authors report on a new database on diamond deposits and production and analyze the relationship between diamonds and armed conflict incidence, finding evidence that secondary diamonds are positively related to the incidence of civil war, especially in countries divided along ethnic lines.

TL;DR: In this article, the authors identify a few lights in the wilderness and briefly outline a program of research on the relationship between resources, the environment, and armed conflict, which suffers from a lack of clarity over what is meant by "environmental conflict", researchers engage in definitional and polemical exercises rather than analysis, and important variables are neglected, notably political and economic factors which have a strong influence on conflict and mediate the influence of resource and environmental factors.

TL;DR: In this article, the authors present a large collection of peer-reviewed writings on the relationship between climate change and security, including a special issue on climate change, which is the largest collection of such articles to date.
