Centre For Geo-Informatics

The Centre for Geo-informatics of Environmental Management and Policy Research Institute (EMPRI) was approved in the 42nd Governing body meeting dated 10.03.2015 and the same was established at EMPRI. EMPRI provides technical as well as research support on various programme involving GIS as a major component.

Environmental sciences are relying progressively on digital spatial data acquired from field investigations, instrument observations and remotely sensed images, analyzed by geographical information systems (GIS), distributed through complex infrastructures, and visualized by and for an ever-increasing variety of users. The technologies supporting these processes are at the core of Geo-informatics.

The application of geospatial technology in different sectors is the demand of current time to take intelligent decisions for sustainable management of natural as well as manmade resources.  The growing awareness and interest in making smart decisions has valued the application of GIS and put forward this technology. The application and benefits of GIS are immeasurable.

GIS technology is one of the solution to meet the huge demand by Government, educational organizations and business for various planning, management and allocation of resources through better understanding complex real world problems more easily by predict the near and far future as well.

Owing to the rapid changes and developments in geo-information acquisition, analysis and dissemination, EMPRI is well-appointed with scientific staff along with technological skills that can keep pace with and validate the relevancy of developments and the quality of the Geo Data, processes and geo-information. The Centre for Geo-informatics division of EMPRI is in constant efforts to strive for excellence to tackle the challenges, to design and develop algorithms, models, and tools that can process the geo-spatial data into trustworthy, actionable information. EMRPI is working on various natural resource conservation projects and programs and almost all projects have a key role of Geo-informatics.

Completed Projects:

  • Evolving Sustainable Conservation Strategies for Water-Bodies of Mysore – Nanjangud Local Planning Area
  • Assessment Derived Conservation Strategies for the Major Lakes of Karnataka- Bangalore phase I
  • Water Safety Plan for Bangalore – A Quality Based Approach to Water Supply Service Delivery
  • Comprehensive Assessment of Thippagondanahalli Reservoir Catchment Area and its Preservation Zones​​
  • Study the Impact of Climate Change on  Incidence of  Vector bo​rne diseases and vulnerability mapping for Karnataka

Ongoing Projects:

  • Assessmen​t of Current Status of Cauvery River in Karnataka and study of 300m buffer zone on both sides of the river
  • Successfully governing water resources requires sound scientific understanding of the watercourse and the challenges it is facing. Linking of scientific knowledge to policy decisions concerning the sustainable development of the river basins is the key for effective governance and the long-term sustainable development of the watercourse.

    Most of the River basins globally are currently threatened with Landuse-Landcover changes associated with over-extraction, pollution, damming and infrastructural development as well as the impact of climate change. If left unaddressed, the pressure on the river basins, as riparian States compete for its limited supplies, is only going to exacerbate any chances of freshwater disputes between them.

    Declaration of buffer zones as eco sensitive zone is one of the ways to give protection to the area from further degradation. This will also strengthen the carrying capacity of the area by adding more protection and by reducing the negative impacts of manmade interventions (industrial, agricultural, unplanned development etc.). The eco-sensitive zone would act as a “shock absorber” for the protected areas and also act as a transition zone from areas of high protection to areas involving lesser protection.

    The river Cauvery is the source for an extensive “irrigation system”, water for household consumption and for hydroelectric power. The river has supported irrigated agriculture for centuries and served as the lifeblood of the ancient kingdoms and modern cities of South India. The river system also supports an important riverine fishery. The Cauvery River Basin is an especially valuable resource for the people of Karnataka because they directly depend upon it for surface water, agricultural products, numerous forms of outdoor recreation, tourism industries, and for their enjoyment of its plants and wildlife.

    Tributaries and landscapes within the watersheds of Cauvery river, the 300 m buffer zone on both the side have undergone tremendous alteration in the past, which has resulted in the loss of natural wetland vegetation and hydrologic characteristics of the landscape. Along certain stretches of River Cauvery, intensive agriculture, abstraction of water for irrigation and drinking, washing cloths and utensils, discharging of sewage waste, sand dredging, tourist activities, boating, fishing, open defecation and religious ritual activities are some of the anthropogenic activities practiced.

    By observing the current situation of Cauvery river and its basin which is getting polluted and the quality, quantity of water is deteriorating with time, with reference to the W.P. No. 13473/1998 (PIL) and W.P. No. 33645/1998 (PIL), Hon’ble High court legal services committee, Bangalore & the Hon’ble Lok Adalat held at Mysore on 4thJanuary 2014, discussed many issues concerned with Cauvery river and its river basin in Karnataka.

    By observing the current situation of Cauvery river and its basin which is getting polluted and the quality, quantity of water is deteriorating with time, with reference to the W.P. No. 13473/1998 (PIL) and W.P. No. 33645/1998 (PIL), Hon’ble High court legal services committee, Bangalore & the Hon’ble Lok Adalat held at Mysore on 4th January 2014, discussed many issues of Cauvery river and river basin in Karnataka. With this background Secretary of Government, Department of Forest, Ecology & Environment, GoK, in its letter No. APG 22 ENV 2014, dated 23rd June 2014, requested EMPRI to takeup the study. Additionally in the Research and Training Advisory Committee Meeting (RTAC) Hon’ble Dr. A.N. Yellappa Reddy, member of Honorable High court legal services committee had also recommended EMPRI to take up this work with his valuable suggestions.

    In view of above, The Environmental Management and Policy Research Institute (EMPRI) has taken up this project on “Assessment of Current Status of Cauvery River in Karnataka and study of 300m buffer zone on both sides of the river”, which has been entrusted by the Hon’ble Lok Adalat.

    The baseline information available, allows us to draw the attention of the authorities towards the management and rejuvenation of Cauvery water for sustainable management in the catchment area, its biodiversity (including terrestrial and aquatic flora and fauna) and conservation of wetlands.

    The overall objective of the project is to evaluate 300m buffer zone on both sides of river Cauvery as eco-sensitive zone so as to minimize the negative impacts of certain human activities on the fragile ecosystem encompassing the protected area. The first step towards assertion of eco-sensitive zone for important stretches of protected areas is to do an inventory of the different Landuse patterns. Hence, the present study undertaken encompasses the use of remote sensing and GIS Techniques to assess the Current Landuse-Landcover Status of Cauvery River in Karnataka and study of 300m buffer zone on both sides of the river.
