This issue contains seven articles. 'Climate Change–Conflict Nexus: Framework for Policy-oriented Action' bridges the climate change-conflict gap by providing a framework or lens through which policy-action research on the nexus between climate change and conflict can be designed and implemented. 'Climate Conflicts in the Horn of Africa?' focuses on the climate change–conflict nexus in the Horn of Africa (HoA) – a region that has experienced high conflict levels, and is also prone to climatic fluctuations and natural disasters. 'Transboundary Rivers and Climate Change: African and Asian Rivers' looks at how the global water crisis remains unresolved and water shortages have the potential to threaten global peace, prosperity and stability. 'Key Social Vulnerabilities to Climate Change in South Africa’s Coastal Zones: The Potential for Conflict' suggests that due to coastal development trends, coastal areas are being largely transformed and that the natural resource base is being degraded as a result. 'Addressing Climate-related Conflict: Human Security and Lessons from the Southern Sahelian Belt of Sudan' looks at how the effects of climate change – droughts, desertification, precipitation changes and other weather events especially affect societies where people depend on the environment to make a living and where they lack the capacity to cope, prevent or adapt to sudden or slower, systematic changes. 'Addressing Charcoal Production, Environmental Degradation and Communal Violence in Somalia: The Use of Solar Cookers in Bander Beyla' discusses the effects of charcoal production on the environment, its direct and indirect contributions to violence, and its overall effect on the health of women and girls in war-torn Somalia. 'Collusion and Criminalisation: Fuel Conflict in the Niger Delta' seeks to identify factors that have combined to fuel conflict in the Niger Delta.
