The Bandipur National Park situated in the Western Ghats of Karnataka State, is one of the biodiversity hotspots of the world. During recent years, this park has witnessed repeated fires, affecting considerable areas under vegetation. The temporal satellite data from 1997 to 2006 have been analyzed to map the burnt …
A case study has been conducted to identify suitable sites for water harvesting structures in Soankhad watershed, Punjab using information technologies such as Remote Sensing and Geographical Information System (RS-GIS). The IRS-1C, P6 satellite imagery of the Soankhad watershed was used. The various Thematic maps such as land use map, …
Evaluation of the morphometric parameters requires preparation of drainage map, contour map, ordering of the various streams and measurements of catchment area, perimeter, relative relief, relief ratio, length of drainage channels, drainage density, drainage frequency, bifurcation ratio, texture ratio, circulatory ratio and constant channel maintenance, which help to understand the …
A case study was conducted to find out the groundwater potential zones in Kattakulathur block, Tamil Nadu, India with an aerial extent of 360.60 km2. The thematic maps such as geology, geomorphology, soil hydrological group, land use / land cover and drainage map were prepared for the study area. The …
Quantitative land evaluation procedures, namely USDA Land Capability Classification (LCC) and FAO Land Evaluation Procedure for Soil Site Suitability for various land utilization types have been used to assess the land suitability for different crops and for generating cropping pattern for kharif (summer) and rabi (winter) seasons in a watershed.
Chandigarh: The Dakshin Haryana Bijli Vitran Nigam (DHBVN) has got the approval for two power development and reform projects at Hisar and Ellenabad, under the Restructured Accelerated Power Development and Reforms Programme (R-APDRP) of the Central government. Anurag Aggarwal, Managing Director, DHBVN said the steering committee for R-APDRP constituted by …
Sustainable agricultural productivity over the long term was not a major issue in the 1960s and 1970s, as food resources did not appear to be threatened1. The attention was on producing enough food to overcome the immediate problems of food deficit. But the environmental effects of intensive agriculture, such as …
Deforestation and forest degradation are the major ecological problems in developing countries. It is a dynamic process which can be attributed to various socioeconomic and biophysical factors, resulting in the conversion of forest area into a mosaic of mature forest fragments, pasture and degraded habitat. In this research, a multi-agent …

The debate about best policies for GI has been a long and unfinished one hed one. This article goes into the fundamental issues and provides two complementary perspectives. Firstly, policies about GI in a nation are con are controlled by the very nature of its governance. Secondly, the use of …
The spatial and temporal variability experienced in the weather conditions of a local area as well as the landmass on which they act makes the overall system highly dynamic and therefore complex to understand in terms of its water resources. Watershed management philosophy offers a great deal in handling these …
This study aimed to create a complete GIS base database for the entire sanctuary using ancillary data of the sanctuary as well as using recent technology i.e. Remote Sensing and GIS, habitat characterization pattern of Barnadi WLS, create a decision support system (DSS) of Barnadi WLS using geo-informatics and analyze …
Availability of groundwater varies spatially and temporally depending upon the terrain. The scarcity of water affects the environmental and developmental activities of an area. Construction of small water harvesting structures across streams/watersheds is gaining momentum in recent years. In the present study, potential sites for construction of rainwater harvesting structures …
The Kosi river in north Bihar plains, eastern India presents a challenge in terms of long and recurring flood hazard. Despite a long history of flood control management in the basin for more than 5 decades, the river continues to bring a lot of misery through extensive flooding. This paper …
The current study was taken up to investigate the utility of remote sensing and GIS tools for evaluation of Integrated Wasteland Development Programme (IWDP) implemented during 1997-2001 in Katangidda Nala watershed, Chincholi taluk, Gulbarga district, Karnataka.
The study area is a part of Kagna river basin in the Gulburga district of Karnataka, India. Remote sensing and GIS techniques have proved to be efficient tools in drainage delineation and their updation. These updated drainages have been used for the morphometric analysis. The morphometric analysis was carried out …
This study describes a modeling methodology for using Geographic Information Systems (GIS) tools to identify potential areas for the introduction of supplemental irrigation. In their most simple concept, such areas would be characterized by the presence of arable soils, non-constraining slopes, agricultural land use, and would be within proximity of …
In Syria water harvesting is not much adopted by farmers. One of the reasons is that the agricultural research and extension support services in Syria lack specific and systematic knowledge on potential areas and suitable locations for water harvesting. The objective of this study is to provide a rapid GIS-based …
Mumbai, November 9 After a delay of almost a year, the financial capital is finally set to have Geographical Information System (GIS) enabled maps that will not only record the city
