South Sudan faces severe environmental challenges including frequent flooding, deforestation, and climate vulnerability exacerbated by conflict and weak institutions. With a tropical climate featuring wet and dry seasons, the country experiences above-average rainfall under La Niña conditions, leading to floods impacting agriculture and livelihoods. Deforestation rates remain high, forest coverage is declining, and environmental sustainability policies score very low at 1/6 per World Bank metrics. Over 95% of the population relies on climate-sensitive livelihoods with limited adaptation capacity.
