Abstract

The present paper attempts to study the land man ratio in Kadalundi river basin using geoinformatics. Kadalundi river basin is a medium river basin in Kerala, flowing at a length of 130 km draining an area of 1122 sq. km. The study area owes its natural and demographic significance to its geographical location which gives it a unique identity. There exists a significant man and land relationship which is reflected in the extent of land cover / land use pattern and demographic status of population in the study area. There are several statistical and geospatial methods of analysis which can evaluate the man land relationship among which the most popular method is man land ratio which describes the concentration of people per unit area. However it cannot be used to calculate unit of land available per person as it requires a slight deviation from the normal calculation of man land ratio. This particular research paper focus on the significance of land man ratio to understand the availability of land as a resource for per person and how over population and urbanization lead to stress on the geographical land of Kadalundi river basin. The whole study was carried out based on secondary data and ArcGIS 10.1 software was used to map and analyze the land man ratio in Kadalundi river basin.
