Abstract: In order to understand the landuse pattern of Neyyar river basin, very extensive field investigation was conducted, and the findings were cartographically illustrated with the help of Geographic Information System (GIS), to provide an applicable outlook for a better landuse framing, as landuse has an inevitable role in the mere existence of the river. Geospatial pattern of the present landuse of the study area indicated that the sustainability of this river ecosystem is in danger due to unscientific landuse practices such as deforestation, reclamation of paddy fields, extensive rubber cultivation, sand mining, pollution and agglomerated settlements. The major landuse category observed in this region is settlement with mixed tree crops.
