This study examines the changes that have occurred in the land use of the Monaragala city area during the period from 1985 to 2018. The main objective of this research is to identify land-use changes, trends, and progress of the land use pattern in the study area and the Causes affected to Changes of Land Use patterns in Monaragala City Area. Three Grama Niladhari Divisions belonging to the Monaragala Divisional Secretariat Division were selected as the study area. Because the City area was located in these three GN Divisions.
