See if disaster diplomacy work on climate change http://www.disasterdiplomacy.org/cep.html might help with framing especially the climate change sections of the two books http://www.routledge.com/books/details/9780415679930 and https://doi.org/10.1163/9789004316140

Violence has nothing to do with external factors. It arises from the heart of men - Matthew 15:19 in the Bible :)

Le lien entre la sécurité et le changement climatique englobe tout. Cas de l’Est de la RDC

There is no link between any real climate change and anything else since there is no real climate change that matters, it is only the talk. The farmers e.g. in Holland experience real violence done to them, however, by those who do the talking.

The violence and fighting is occurring so recently I doubt studies have been completed or even started. And its more prevalent in a group of countries VS across the globe. I suggest an internet search for where its being most seen (I agree with rural areas), if newly scarce and dwindling resources are the source of the fighting and who is most often involved. -- I suggest to look and study the findings and comments from the November 2022 UN Climate Change Conference in Sharm el-Sheikh, Egypt. --- In addition, like other farmers world wide, this summer in the western US states many argued & fought over decreasing water resources. I expect water and other resources to decrease from a quickly worsening climate as well as being used as a political weapon (see eastern Europe). With that I'd encourage help find ways to bring change vs adding one more study.
