Land cover dynamics in Greater Chittagong area

Assessment and monitoring of land cover dynamics are essential for the sustainable management of natural resources, environmental protection, biodiversity conservation, and developing sustainable livelihoods, particularly for the rural communities in the Hindu Kush-Himalayan region.

The application provides easy access to the harmonised land cover database developed for Greater Chittagong area over different time slices (1989, 2000 and 2010) and provides user friendly tools for generating statistics to understand the change processes and to support the informed decisions.


The land cover data for the years 1989, 2000 and 2010 have been derived from Landsat images using object based image analysis. The legend is developed in consultation with national partners using Land Cover Classification System (LCCS) from FAO/UNEP.
