South Sudan, known as the Republic of South Sudan, is a landlocked country in Northeastern Africa. The country has the population of approximately 13.1 million people, with 81.8% resides in rural areas, primarily engaging in subsistence agriculture. The climate of South Sudan is similar to tropical climate with high rainfall season, followed by a drier season. Rainfall occurs in a single rainy season from March to November, peaking between May and September. While the southern and eastern parts receive higher rainfall, the country experiences significant climate variability. Consequently, droughts and floods frequently impact livelihoods, particularly in agriculture (Climate Change Knowledge Portal).   

The country is highly vulnerable to climate risks, including rising temperatures, erratic rainfall, prolonged droughts, and severe flooding. Since the 1970s, average temperatures have increased by 1-1.5°C, with projections indicating further warming by 2060 (African Development Bank). These climate risks, combined with widespread displacement due to ongoing conflict, have intensified food insecurity, and increasing the risk of local conflicts. 

To response to these challenges, South Sudan put the major priorities for actions and investments for climate change mitigation and adaptation strategies (USAID South Sudan Climate Vulnerability Profile). These are outlined in its NDC, focus on reducing greenhouse gas emissions through policies in energy, land use, and transport. The country estimates that at least $50 billion is required for mitigation and adaptation efforts by 2030. However, these estimates remain approximate, and further analysis is needed to refine support requirements.
