This paper observes that the resurgence of conflict in 2013 in South Sudan has further been exacerbated by the negative impacts of climate change. The study is approached from a human security perspective and debates the nexus between climate change and conflict. It situates how climate change is worsening an already fragile context by aggravating food insecurity and contributing to a humanitarian crisis. The study offers several policy recommendations, including the inclusion of climate forecasting tools and early warning mechanisms for pre-emptive responses, afforestation, and the accounting of climate change in peace negotiations.
