The main objective of the present paper is to get a vivid idea about the methods and techniques of the previous work related to ‘Impact of Changes in Landuse on Environment in Southwest Birbhum Distrct, West Bengal’ on international, national and regional level. Finally based on previous literature research gaps have been identified and an attempt has been taken to fill up the voids. The present work has been divided into three parts. The first part tries to analyze the conceptual aspect by explaining the term environment, landuse/land cover, changing landuse/land cover,and environmental impact. The second part deals with previous literature and the concluding part identifies the research gaps and provides probable solutions to fill up the voids.
