Geospatial Assessment of Land Use and Land Cover Changes in Debrigarh Wildlife Sanctuary, Odisha: A Twenty-Year Perspective
Abstract: Among the recorded dynamic processes on the surface of the earth is the change in land use and land cover (LULC) pattern as an outcome of several anthropogenic practices. Planning, development, and management of land for sustainable usage of land depend on plotting and tracing the vagaries in LULC. Anthropogenic activity, generally for forestry and food production, is altering the land surface. The steadily diminishing landscape also has tragic implications …

The Impact of Linear Infrastructure on Land Utilization using GIS
Abstract: In all urban centers of the Tigray region and the nation as whole, there is inefficient urban land utilization and development. The bottlenecks in the supply of serviced land are caused by inadequate provision of infrastructure and services. Moreover, the government often provides arterial infrastructure, leaving the provision of secondary and tertiary infrastructure to individuals or private sector developers. As a result private sectors or individuals assembled raw land only. …

MSW Landfill Site Selection for Hyderabad City Using GIS and AHP
Abstract: One of the significant difficulties in most of massive urban areas is lack of land for waste disposal. According to UN world population prospects, about 54% of the population resides in urban areas which are anticipated to rise to 66% by 2050. India is estimated to add 404 million urban dwellers by 2050. The substantial increase in the population growth has lead to the immense generation of waste. 5000 TPD …

Avalanche Hazard Mapping along Manali-patsio Road Axis (Himachal Pradesh, India) Using Advanced Geo-Informatics Techniques
Abstract: Avalanche occurrence is quite a hazardous and unpredictable natural phenomenon. A large number of factors that are associated with its occurrence make it quite difficult to assess hazard in hilly areas. There are two main groups of variables that define the avalanche hazard – meteorological conditions and terrain characteristics. Due to the stable nature along the time, terrain parameters are easier to map. The purpose of this work is to …
