Modelling the forest transition in Central Western Ghats, India
T. V. Ramachandra,Bharath Setturu,K. S. Rajan,M. D. Subash Chandran 대한공간정보학회 2017 Spatial Information Research Vol.25 No.1
The Western Ghats forms an important watershed for the entire peninsular India, being the source of 37 west flowing rivers and three major east flowing rivers and their numerous tributaries. However, deforestation due to large scale land cover changes has affected the water sustenance in the region evident from the quantity and duration of water availability during post monsoon period. Land use Land cover changes accelerated by unplanned anthropogenic activities have been the prime mover of global warming and consequent changes in the climate. This necessitates appropriate resource management with an understanding of drivers. Geo-visualization of landscape transitions considering the influential agents will aid in formulating strategies to mitigate global warming. Uttara Kannada district in the Central Western Ghats has the distinction of having highest forest cover in the country and this region is now experiencing rapid forest cover changes. Factors inducing changes in the land cover are normalized through fuzzyfication, considered for Multi criteria Evaluation using Analytical Hierarchy Process (AHP) under high protection and low protection scenarios. Likely land use transitions by 2022 across zones based on transitions during 2004–2007, 2007–2010, 2010–2013 was done through cellular automata and Markov chain process (MC). The analyses highlight the loss of forest cover by 66.55–56.76% by 2022 in the coastal zone with escalating population density. Similar situation of 65.98–55.62% decline in Sahyadri region is noticed with execution of dams, hydroelectric projects and monoculture plantations. Lower transitions as compared with the second scenario highlights regulatory framework’s role in protection. However, forests in plain region show loss of 27.38–11.09% in both scenarios due to population pressure and market induced land cover changes. This necessitates policy interventions by the federal government to mitigate forest loss towards sustainable development.

Modeling urban dynamics along two major industrial corridors in India
T. V. Ramachandra,Jefferey M. Sellers,H. A. Bharath,S. Vinay 대한공간정보학회 2019 Spatial Information Research Vol.27 No.1
Rapid urban growth and consequent sprawl have been a major concern in urban planning towards the provision of basic amenities and infrastructure. The current research was undertaken as per the recommendations of brainstorming session involving stakeholders from academia, government agencies and industry. The outcome of this study is expected to provide the vital inputs to the federal government to provision basic amenities and smart infrastructure, to boost the industrial growth, while maintaining the local ecology and environment and support local livelihood. Spatial patterns of land use dynamics have been analysed in two major corridors (with 10 km buffer on either side). During the past two decades, the urban growth is about 441% along Mumbai–Pune Industrial corridor and 276% along Chennai–Bangalore–Mangalore corridor. The prediction of likely growth has been done using Markov-cellular automation model, accounting fuzzy behavior of agents. Spatial metrics confirm that the core urban areas of major cities have concentrated growth and sprawl at the outskirts. Prediction model estimates that urban area would increase to 47.1% by 2027 in Mumbai– Pune corridor and to 35.4% in 2029 in Chennai–Mangalore corridor. This study aids in pre-visualising the urban growth to evolve appropriate management strategies to mitigate environmental impacts.
