The Umfolozi-Hluhluwe Park, the first designated protected area in Africa, was established in 1895. It is a flagship protected area of Ezemvelo KwaZulu-NatalWildlife (EKZNW) known for having a long history of innovative conservation research and development of conservation techniques. It is a park of great importance in terms of its future ecological use, and its natural and cultural heritage. Remote sensing systems give an imposing chance to illuminate the administration of secured regions, permitting e.g. to track dangers, biodiversity status and the effects of protection activities. The using of the persistence of vegetation changes images is a method for identifying changes in land use patterns and land cover. Especially with the African continent, where environmental changes go to extreme levels, the benefits of relying on more novel and more powerful technologies in imaging and remote sensing data are immense. One particular index that is popularly used is the normalized difference vegetation index (NDVI). Changing in NDVI indicate changes in biological activities. Hence, it is best used for mapping and monitoring fire disturbance, forest clear-cut activity, and other land-cover changes. Using NDVI to analyze the vegetation and the land use and land cover change in Umfolozi-Hluhluwe Park is a good approach for vegetation changes mapping. This research found the dynamics of the persistence of vegetation changes between 2001 and 2016 in both seasons summer and winter as well as the effects of land use on the timing and magnitude of energy and carbon exchange in temperate agricultural areas in Umfolozi-Hluhluwe park
