The Panna National Park (now Biosphere Reserve) is a part of the central Indian Highlands and located in north-central Madhya Pradesh, India. The study is concerned with the major units of geomorphological mapping to develop baseline data for Panna National Park. The present study can be used for wild life habitat characterization and process modeling of wild animal habitats (like Penthra Tigris, Aix Axis etc.). The geomorphological maps were prepared through a combination of knowledge base and detailed visualization in a geographical information system (GIS). Survey of India (SOI) Toposheets on 1:50,000 scale were geo-referenced, a geo-database prepared, a symbol-based digitization was carried out and rectification into polygons was done for generation of the geomorphological map. Finally this study illustrates how geomorphological mapping can be integrated through geographical information system and remote sensing for evaluation of habitat suitability on a detailed scale for wildlife conservation.

GIS technology in such studies is proved to be the powerful tool especially in water utility applications, engineering, constructions and operational purposes. The technique provides advanced automation into number of applications that use to be time consuming and tedious before. The attempt is an approach to give glimpse of automation techniques used in ground water analysis in JBS pilot area. Jaunpur Branch Sub Basin, Ground Water Levels and Sub Irrigation Units Jaunpur Canal is a branch canal of the Sarda Sahayak Feeder Canal System of about 650 cumec capacity, off-taking from the Sarda River and fed by Sarda Link Channel of 480 cumec capacity from the Ghaghra River. The 123-cumecs Jaunpur Branch canal irrigates about 3 lakh ha between the Gomti and the Sai Rivers. Nevertheless, the gross command area, which can be irrigated from the Jaunpur offtake, is about 542000 ha of the Gomti-Sai doab. The region of study is Jaunpur Branch Sub Basin, pilot area of the Ghaghara Gomti Basin that comes under Uttar Pradesh Water Sector Restructuring Project (UPWSRP). Under the same (UPWSRP) program, the UP Irrigation Department recently installed more than 475 piezometers with Automatic Digital Water Level Recorders (ADWLR) to monitor groundwater levels in JBS. Six hourly groundwater level data of pre monsoon and post-monsoon 2005 onwards as obtained from piezometer is required to be summarized as per one hundred forty six Sub Irrigation Units. Methodology The tool developed for ground water depth analysis is compatible in ARCGIS environment. The interface interpolates the data using inverse distance weighted algorithm and produces the output in table as well as raster formats. The tool requires three input files first the peizometer data point file, second the polygon file that is Sub Irrigation Units (it may be any other polygon layer of the same area, such as block or MSB layer), according to which the statistics have to be calculated, and the ground water depth table in *.dbf format, which has the six hourly data corresponding to every peizometer in the point shape file (Fig.1 & Table 1)

The entire study area is commanded by the Jaunpur Branch canal with 123-cumec design capacity under the SardaSahayak system. In the study geo-database has been prepared based on data collection and to capture information on climate, agriculture, surface and groundwater hydrology, irrigation and drainage network, water demands (Irrigation, domestic, industrial, hydropower, environment), socioeconomic and demographic details, topography, water quality etc. The finding reveals that apart from canals, a significant amount of groundwater resources is also being utilized by private and government tubewells. Contribution of government tubewells is much less. Waterlogging appears to be localized in nature and exists predominantly in canal head and middle reaches where groundwater utilization is comparatively less and seepage from canals is higher. It is clear from these illustrations that rice being less sensitive to waterlogging, it exhibits higher productivity in head and middle reaches of canal where canal supply is adequate and reliable in the Kharif. Quite expectedly, it shows lower productivity in the canal tails and out of command areas as canal irrigation is either not available or unreliable. Wheat scenario suggests that the productivity is higher in middle and tail reaches where waterlogging is less and groundwater is used more. The cropping intensity during both Kharif and Rabi seasons is comparatively low along head reaches of canals. RS analyses clearly suggest that cropping intensity is lesser especially along branch and distributary canals in head and middle reaches.

Global average temperatures are projected by The United Nations & World Health Organization to increase between 1.4 to 5.8 O C by the end of this century: an associated rise in sea level is also expected. The number of people at risk from flooding by coastal storm surgery is projected to increase from the current 75 million to 200 million in a scenario of mid-range climate change, in which a rise in the sea level of 9-88 cm is envisaged by the 2100s. [3] The study based by NASA'S Goddard Institute 2005 was the warmest year since reliable data available in the late 1800 century. The Women's are expected to be affected more than Men from climate change due to they have to take over the biggest part of the additional work burden, specifically additional care work, and the burden of nurturing the family, as well as providing the daily essentials. The aims of this paper are to briefly summaries what are known about likely impacts of climate change on human health.

Habitat zones where prey populations are abundant are likely to be preferred by the tiger in comparison to those where they are scarce or absent. An area having a high density of road would be avoided by wild animals as compared to an area with few or no roads because there is a high traffic and constant noise. Habitat suitability index (HSI) models have been used to evaluate wildlife habitat. These models are based on functional relationships between wildlife and habitat variables. Values of habitat variables (e.g., herbaceous canopy cover, tree canopy cover, tree height) are related to habitat quality on a suitability index (SI) scale from 0 = " not habitat " to 1 = " habitat of maximum suitability. " Habitat suitability index scores, also on a 0–1 scale, are usually calculated using a mathematical formula representing hypothesized relationships among the individual SIs. Tiger (Panthera tigris) prefer core habitats, generally avoid area with high edge density. In the study area landscape, the Ken River is the perennial water sources; Prey species of tiger and the Tiger also preferred areas proximate to perennial water sources is favored. Tigers, under normal circumstances of human settlement, avoid traversing through such areas. Tiger " s preferred prey includes in the study area, this group is commonly represented by Chital (Axis axis), Sambar (Cervus unicolor), Wild-boar (Sus scrofa), Barking deer (Muntiacus muntjak), and Nilgai (Boselaphus tragocamelus) were also encountered in the study area.

and rainfall will increase 15-30% in 21 Centaury. While the global surface temperature is projected to
increase by 1-4oC from 2100 for low emission scenario and 2.5-5.8oC for higher emission scenario in
the atmosphere. This Paper has been prepared with the objects of provide key information on the
impacts of climate on Indian agriculture. The greenhouses gas emissions increases day by day in the
atmosphere from the many sources such as industrial sources crop production and fossil fuel
combustion. These are the major sources for the climate change. The global increases in carbon
dioxide concentration are due primarily to fossil fuel use and land use change, while those of methane
and nitrous oxide are primarily due to agriculture. Currently Available general circulation models (GCMs)
suggest that the area-averaged annual mean warming would be about 3°C in the decade of the 2050s
and about 5°C in the decade of the 2080s over the land regions of Asia as a result of future increases
in atmospheric concentration of greenhouse gases. In Rajasthan, a 2°C rise in temperature was
estimated to reduce production of pearl millet by 10-15 per cent (Y S Ramakrishna et al.,). The state of
Madhya Pradesh, where soybean is grown on 77 per cent of all agricultural land, could dubiously
benefit from an increase in carbon dioxide in the atmosphere.

Water samples were collected monthly from the six sampling sites of the lake over two years (Jan. 2008 to Dec. 2009) for analysis of various physico-chemical parameters. Results indicated higher values of electrical conductivity (422mg/l), turbidity (33.9 mg/l), total dissolved solids (673.25 mg/l), total hardness (177.58 mg/l), alkalinity (217.16 mg/l), chlorides (81.52 mg/l), biological oxygen demand (17.47 mg/l), chemical oxygen demand (54.74 mg/l), phosphate (2.35 mg/l) and nitrate (1.46 mg/l) than the prescribed standards. The study revealed low Dissolved Oxygen content than prescribed standards and the water was alkaline and hard. There was seasonal variation in water quality parameters. The results have clearly indicated that this lake is polluted and eutrophic in nature due to discharge of sewage and other anthropogenic activities. Abstract

The purpose of this study was to produce habitat suitability model for the Chital in Panna National Park India (North latitude 24°27′ and 24°46′ and East longitude 79°45′ & 80°9′). Habitats were evaluated using Multi criteria analysis and habitat suitability index with remote sensing and GIS. Satellite imageries of LISS-III (IRS-P6, LISS-III) of study area were digitally processed. To generate collateral data, topographic maps were analyzed in a GIS framework. Layers of different variables such as: Land use/Land cover, forest density, proximity to disturbances and water resources and a digital terrain model were created from satellite and toposgraphic sheets. In the study area landscape, there are an only Ken River is the perennial water sources, the surrounding of the river is more suitable habitat for chital. Human settlements areas are usually avoided by wild animals. Species like the chital, which prefer edge habitats, generally avoid core areas of park.
