More than a quarter of the total geographic area (TGA)-96.4 million hectares (mha) or 29.32%-in India is undergoing degradation as per this Desertification and Land Degradation Atlas, released in June by ISRO Space Applications Centre (SAC).

Better matching of land use with its sustainable potential is a “no-regrets” strategy for sustainably increasing agricultural production on existing land, targeting restoration efforts to where they are likely to be most successful, and guiding biodiversity conservation initiatives.

Nashik: The disaster-prone locations in 14 vulnerable districts in the state will soon be mapped using Global Information System (GIS) for better identification of such spots and quick response in

For more effective management of water distribution network in an arid region, Mapinfo GIS (8.0) software was coupled with a hydraulic model (EPANET 2.0) and applied to a case study region, Chetouane, situated in the north-west of Algeria. The area is characterized not only by water scarcity but also by poor water management practices. The results showed that a combination of GIS and modeling permits network operators to better analyze malfunctions with a resulting more rapid response as well as facilitating in an improved understanding of the work performed on the network.

Accurate estimation of the groundwater budget requires good estimate of flux across the boundary of a region. Different methods and techniques are available to estimate recharge to groundwater; however methods for estimation of flux across boundaries are not available. The present article represents a GISbased methodology to estimate the groundwater flow rate and volume of water flux across the boundary. Groundwater level data (pre-monsoon and postmonsoon) are used to derive detailed maps like flow direction, hydraulic gradient and velocity component perpendicular to the boundary.

Prevalence of walking and cycling for transport is low and varies greatly across countries. Few studies have examined neighborhood perceptions related to walking and cycling for transport in different countries. Therefore, it is challenging to prioritize appropriate built-environment interventions. The aim of this study was to examine the strength and shape of the relationship between adults’ neighborhood perceptions and walking and cycling for transport across diverse environments.

This study is an attempt to quantify the impact of climate change on the hydrology of Armur watershed in Godavari river basin, India. A GIS-based semi-distributed hydrological model, soil and water assessment tool (SWAT) has been employed to estimate the water balance components on the basis of unique combinations of slope, soil and land cover classes for the base line (1961–1990) and future climate scenarios (2071–2100). Sensitivity analysis of the model has been performed to identify the most critical parameters of the watershed.

NAVI MUMBAI: The GPS-based tree census recorded approximately 8.5 lakh trees in the city till the end of January, a significant increase when compared to the 4.79 lakh trees counted in 2006 census.

The inventory will be supported by satellite images and GIS
