Land Cover Change Assessment of Pakke Tiger Reserve (PTR), East Kameng District of Arunachal Pradesh
Abstract: Land cover change is a global concern and a major contributor to the degradation of biodiversity loss, more specifically in reserved forest areas. As the human population increases, the forest covers of unprotected areas are used up and slowly the protected areas are being intruded to meet the needs. Presently, such cases of land cover changes and biodiversity losses in protected areas have been reported from many parts of the …

Quantification of River Bank Erosion, Accretion and Its Effect on Land Use: A Case Study of the Ganges (Left Bank) Upstream of Farakka Barrage, Malda District, West Bengal
Abstract: Bank erosion is mainly a physical process of river dynamics that causes threat to the riparian and floodplain structures, engulfs fertile agricultural land, homes, means of livelihood and assets of the people. Along with physical causes, anthropogenic activities disturb the equilibrium of the river dynamics along the river stretch and accelerate the rate of bank erosion. The study focuses to quantify the decadal and mouza-wise erosion and accretion along the …

Detecting Land Use and Land Cover and Land Surface Temperature Change in Lilongwe City, Malawi
Abstract: In south east Africa, Lilongwe city had an observed rapid population growth over the past decade and a half. The same city also had recently observed increased temperatures and adverse weather conditions such as occassional heavy storms which caused severe flooding in January 2017 and December 2017. It was therefore thought wise to do a land use and land cover (LULC) study of the city over time to detect land …
