Over the past two decades, adelphi has built up a strong, global evidence base of how climate and environmental change links with conflict, compounding factors that drive insecurity such as lack of social cohesion and livelihood options. Our work, especially with implementing partners in fragile contests, also shows however how climate and environmental action also offer entry points to foster cooperation.

Land has often been at the heart of conflict dynamics. Yet land and ecosystem restoration can also offer pathways for improving cooperation between countries and people, thereby ultimately contributing to preventing conflicts and building peace.

Whilst at first sight it may not seem explicitly so, the new IPCC report contains a lot of important findings on the links between climate change and conflict.

This policy paper examines how land-based carbon credit schemes can displace local communities and Indigenous peoples, particularly in areas with contested land tenure. Drawing on cases from Kenya, Indonesia and Peru, it argues for integrating conflict sensitivity and equity considerations into the design of climate mitigation interventions.

This policy brief outlines key policies, programming, finance opportunities and the implications of current geopolitical changes to dynamics at the nature-security nexus. It also provides recommendations to address the complex and evolving interlinkages between nature, peace, and security.

This pioneering assessment offers the first integrated analysis of climate resilience, peacebuilding, and gender dynamics in Sri Lanka, grounded in field research across four districts—Badulla, Batticaloa, Hambantota, and Mullaitivu. The report provides actionable insights and locally tailored recommendations to support inclusive governance, equitable climate adaptation, and strengthened social cohesion.

This report sets the political case for land restoration as a powerful route towards international peace and security, identifies key enablers for land restoration to promote cooperation between countries, and outlines recommendations to elevate the land, peace and security agenda and secure more and better financing.

The Weathering Risk synthesis report identifies nine pressing global climate security trends and opportunities based on 43 case studies, assessments, mapping exercises and scenario-based analyses produced during the first phase of Weathering Risk.

Climate uncertainty, when thrown into the mix of South Asia’s vast and varied geography, rich biodiversity, and complex socio-economic makeup, leads to a web of risks. This report presents climate security risks faced by the region and an overview of the current policy landscape.

This practical note calls on climate, peace and security researchers, practitioners and policymakers to mainstream inclusion throughout all their areas of work.

70 percent of climate vulnerable countries are the most fragile. This should mean that these countries are prioritised by climate finance. Yet, the reality is the opposite. Access to climate finance for fragile and conflict countries is often hindered by structural, technical and institutional barriers.

Land and natural resources can be connected with conflict dynamics, from local disputes to international tensions. Restoring ecosystems can bring communities together, build trust, and foster cooperation, laying the groundwork for peace.
