This population-based prospective cohort study was conducted in Ludhiana, Punjab, Northwest India. All first-ever stroke patients (≥18 years) were included between March 2010 and March 2013 using WHO Stepwise Approach Surveillance methodology from the city. Stroke patient data were obtained from hospitals, scan centers, and general practitioners, and details of deaths from the Municipal Corporation. Out of 7,199 stroke patients recruited, 3,441 were included in final analysis. The mean age was 59 ± 15 years. The annual incidence rate was 140/100,000 (95% confidence interval [CI] 133-147) and age-adjusted incidence rate was 130/100,000 (95% CI 123-137). The annual incidence rate for stroke in the young (18-49 years) was 46/100,000 (95% CI 41-51). The case fatality at 28 days was 22%. Patients above 60 years of age (p = 0.03) an...

The anomalous river flow, abrupt changes in flow direction, angular drainage, compressed meanders, asymmetry of river bends, high channel sinuosity, abandoned channels, waterlogged and marshy areas observed along the courses of Beas and Sutlej rivers and their tributaries indicate tectonically active nature of the terrain. The strong control exercised by the NE-SW and NW-SE trending lineaments on the drainage network is well evident in the form of long straightened slope deviatory courses, definite changes in channel pattern and sharp knee bend turns taken by the seasonal rivulets. The asymmetric and elongated nature of watersheds and straight to curvilinear mountain fronts quantified through morphotectonic analysis are characteristic of tectonically active settings and further corroborate the evidences of active tectonics.

Large number of people consumes ground water as it is easily available through open well / bore well / tubewell. The quality of water plays a prominent role in promoting human health. The study discusses the usage of Information System for publishing the drinking water quality on to web portal. Element wise and integrated ground water quality maps are prepared for the parameters viz. pH, Total Alkalinity, Total Hardness, Total Dissolved Solids, Chloride, Fluoride, Nitrate, Iron and Sulphate. The ground water quality maps were studied with respect to different thematic maps which were prepared using Remote Sensing and GIS techniques. A spatial interpolation technique, IDW (Inverse Distance Weighting) was used to obtain the spatial distribution of ground water quality parameters. The objective of the current study were developing a Web GIS based Information System with the help of Postgress SQL, Map Guide a...

Remote Sensing and GIS (Geographical Information System) techniques can be extremely useful in accurate mapping and quantification of waterlogged area and salt-affected soils. Thus helping in preparing a sound database required for taking up various reclamative and preventive measures. In this study visual interpretation of satellite data, IRS 1D LISS III + PAN merged data of 11 th March 2001 and IRS 1D LISS III data of 2 nd September 2001, authenticated by ground truth was carried out for delineation of pre monsoon and post monsoon waterlogged areas and pre monsoon salt-affected soils in Muktsar district. The area affected by waterlogging is found to be 1116.13 ha (0.42%) and 1802.42ha (0.68%) respectively during pre and post monsoon season. The land affected by salinity during pre monsoon is 1320.91ha (0.50%).The waterlogging follows a north-east to south-west direction and is predominant along the western side of twin canals (Sirhind and Rajasthan Feeder). Gidderbaha tehsil with 387.15ha (0.58%) during pre monsoon and Muktsar tehsil with 695.18ha (0.77%) during post monsoon is most affected by waterlogging, while Muktsar tehsil with 774.01ha (0.86%) is most affected by salinity during pre monsoon season. Improper alignment of canals, canal seepage, drainage congestion, brackish groundwater, faulty irrigation practices and cultivation of high water requirement crops are some of the factors contributing to the problem. These problems are further compounded by natural factors such as existence of topographic depressions, buried palaeochannels, absence of natural drainage and incessant rains.

In order to predict the long term effect of ground water use on the soils, the soils and ground water quality maps of Muktsar district, Punjab were prepared, digitsed and integrated using ArcInfo GIS to generate an integrated map showing varying degrees of relative sensitivity to secondary soil salinisation. The map depicts eight mapping units indicating fine textured soils as highly sensitive(14% of TGA), medium textured soils as moderately sensitive (38%), coarse textured soils as less/low sensitive(10%) and the soils with good ground water as non-sensitive(37%) to secondary salinisation. The study indicates that 62% area is prone to secondary salinisation if ground water alone is used for irrigation, unabatedly. The causes of secondary soil salinisation have also been discussed.

With the increasing use of remote sensing and GIS combine, integrated studies are being carried out to understand area specific problems. Panchromatic aerial photographs (March, 1991) on 1:20,000 scale and IRS 1A/1B data of 1991 and 1992 were visually interpreted to prepare various thematic maps viz., geomorphology, drainage, land use, soil etc of Talwara block, Hoshiarpur district, Punjab. Surface and sub-surface soil samples were collected and analysed to prepare soil and soil fertility maps. These maps were digitized, and integrated in Arc/Info GIS. All these maps were integrated in GIS to generate resource constraints map. Three major constraints namely physical, chemical and hydrological were identified and recommendations for rational use of various categories of land were made.

Urban sprawl mapping of Chandigarh was undertaken under NRIS project to develop urban information system. IRS-ID LISS III and PAN merged data on 1:12,500 scale was interpreted. On screen digitization was carried out to demarcate various landuse categories. Various thematic maps viz. Geomorphology, Soils, Landuse, Drainage, Transport and Railway Network, Surface Waterbodies were prepared. Reports and other auxiliary data were also referred to generate infrastructural facilities maps like Residential/Commercial areas, Industrial Complexes, Educational and Medical Facilities, Religious and Historical places, Sewerage and Storm Water Drainage Network, Bus Stands, Railway Station and newly developing sectors etc.

Hence, development of groundwater gets first priority, both at individual as well as governmental level, for different uses. However, the distribution of groundwater is not uniform throughout the state and is subject to wide spatio-temporal variations depending on the lithology, geomorphology and nature of aquifer. Satellite data provides cost and time effective information on factors governing the groundwater condition. The study mainly deals with the integrated approach of remote sensing in conjunction with field surveys and GIS technique to hydrogeomorphological mapping and demarcation of groundwater potential zones in the state on 1:50,000 scale. The prospect zones have been delineated by deriving the hydrogeomorphological units through integration of various thematic maps in respect of geology, geomorphology, structures, hydrology and base map details throu...

The groundwater quality decreases due to the solid waste from urban and industrial nodes, rapid use of insecticides and pesticides in agricultural practices. In this study, ground water quality maps for Rupnagar district of Punjab has been prepared using
geospatial interpolation technique through Inverse Distance Weighted (IDW) approach. IDW technique has been used for major ground water quality parameters observed from the field samples like Arsenic, Hardness, pH, Iron, Fluoride, TDS, and Sulphate. To assess the ground water quality of the Rupnagar district, total 280 numbers of samples from various sources of tubewells for both pre and post monsoon have collected. Out of which, 80 to 113 samples found Iron with non potable limits ranging 0.3-1.1mg/l and 0.3-
1.02mg/l according to BIS standard for both the seasons respectively. Chamkaur Sahib, Rupnagar, Morinda blocks have been found non potable limit of iron in both pre & post-monsoon. 11 to 52 samples in this region have sulphate with permissible limits in both the season ranging 200-400mg/l and 201-400mg/l. But arsenic had acceptable limit in both the season. Various parameters-wise ground water quality map is generated using the range values of drinking water quality to know the distribution of different parameters and diversification in the concentration of different elements. These maps are very much needful for human being to expand awareness among the people to maintain the Cleanness of water at their highest quality and purity levels to achieve a healthy life.
