At the same time land degradation because of desertification, soil salinity, waterlogging, floods/droughts, excessive soil erosion and unscientific agricultural practices has resulted in the creation of vast stretches of wastelands. This has necessitated adoption of scientific measures for increasing land productivity and bringing more areas under cultivation/forests. In the present study, the multi#temporal satellite images of IRS P6 LISS#III were used to map wastelands dynamics over different seasons. An attempt has also been made to evaluate the potential of high spatial resolution LISS IV (5.8 m) data over moderate spatial resolution LISS#III data (23.5 m) from the Indian Remote Sensing Satellite for delineation of wastelands in a portion of the Indo#Gangetic plains of northern India. Visual interpretation based on image characteristics and a prior knowledge of the study area was used to delineate wasteland classes. Using LISS III data, 1372.92 and 605.90 hectares of land areas are identified as affected by seasonal and permanent waterlogged respectively, and using LISS IV, 1113.33 and 105.84 hectares of land areas are identified as affected by seasonal and permanent waterlogged respectively. Wasteland classes such as seasonal and permanent waterlogged could be further separated into wasteland classes such as land with dense scrub, land with open scrub, degraded pastures/grazing lands and degraded land under plantation using higher resolution satellite data.

The main objective of the present investigation is to identify and map the surface extent of salt affected and waterlogged areas during pre-monsoon and post-monsoon season using multi-temporal satellite images and its relationship with soil, rainfall, seasonal groundwater fluctuation and canal command areas. For this purpose, Satellite images from IRS P6, LlSS-III sensor, on a scale of 1:50,000 have been used for delineation of thematic layers such as salt affected and waterlogged areas. The area covered under post monsoon waterlogging (seasonal) comprised of as 114.79 sq km area which is 3.60% of the study area whereas post monsoon waterlogging (permanent) comprised of 89.37 sq km area, which is 2.80% of the study area. The map depicting salt affected soils in the area indicates calcareous fine loamy, coarse-loamy, fine loamy and very fine soil comprising 2799.43 sq km, 9.26 sq km 363.73 sq km and 2.80 sq km area respectively. The monthly TRMM 3B43 rainfall data for the period of 1998-2009 covering the month of June to September shows rainfall varies from less than 965 mm to 1165 mm in the entire state. Depth to groundwater level recorded at select locations by Central Ground Water Board (CGWB), Government of India, for the period 2004-2005 during pre and post monsoon period indicated that a large portion of the area is under groundwater induced waterlogging conditions where groundwater occurs at a depth of 0-3 m below ground surface. The soil and rainfall map clearly specifies that salinity are pre dominant in areas with shallow groundwater levels and high rainfall. Canal command areas comprised the highest waterlogging and salt affected areas in their vicinity as a result of seepage and over irrigation.

The study analyzed the magnitude and direction of temporal LULC changes for two consecutive periods; 1989–2009. The temporal change patterns of LULC were analyzed through interpretation of LANDSAT imagery. Final land cover maps produced under four major classes after a supervised (maximum likelihood) classification exercise. Results of the study revealed that the study area has undergone substantial LULC changes, primarily a shift from natural cover into managed agro-systems which is apparently attributed to the increasing both human and livestock pressure. This shows that, most of the previously forest covered and grass lands are shifted to the rapidly expanding farm land use classes. The findings of this study suggested that the rate of LULC change over the study period, particularly deforestation due to the expansion of farm land and soil erosion problems need to be given due attention to maintain the stability of the ecosystem.

The comparison of Landuse/land cover classes from 1992-2009 indicates major increase in agricultural land (+115.14% in 2002 and +109.61% in 2009) and built up (+105.49%, in 2002 and 105.73% in 2009) classes with respect to area coverage in Harmu watershed whereas, the area of scrub land (-5.88 in 2002 and -42.95), open forest (-16.39% in 2002 and -80.4% in 2009) and wasteland (-22.56% in 2002 and -27.24% in 2009) classes has decreased. The substantial decrease in wasteland during the period could be attributed to the implementation of government wasteland reclamation measures. The pollution level of Harmu river is high at all sites due to the regular discharge of domestic sewage, disposal of automobile/ workshop waste, increasing settlement nearby the river and garbage which led to water not suitable for drinking as well as for domestic purpose. It was observed that the river/drainage channels were primarily encroached by built up land and few of the drainage channels were extinct due to urban activities.

In the course of recent decades, the quantity of Asian Elephants has dwindled because of human infringement and spontaneous settlements and development along the development courses and halls of this lofty creature. Along these lines, legitimate preservation activities require a point by point spatial database on the courses and passages of Asian Elephant. Human- natural life clashes happen inside the setting of dynamic socio-environmental frameworks. Understanding these contentions at generally more extensive spatial and transient scales gives a knowledge into the contention situations crosswise over bigger territory and changes in their spread and power over a wide time frame. This information would be able to give vigorous contributions to arrangement making for the locale on the issue. Then again, understanding these contentions at generally littler spatio-fleeting scale may be helpful in moderation of contentions for neighbourhood administration organizations, for example, Forest Department. This locale is much of the time left by elephants from the neighbouring environments of Orissa and Jharkhand looking for better natural surroundings and regularly entering human residences and farming fields bringing about clashes with people. Satellite images and ground data were utilized for Land use/land cover mapping and identification of contention zones. In the present study, data was utilized to dole out weights to the three elements, viz., types of vegetation cover , nearness to water body, and vicinity to human home. In light of the investigation, a passageway for elephant development and movement has been recognized which could be overseen by the state government with a specific end goal to limit human-elephant clashes in the locale.

The present study pertains to the evaluation of control exerted by various factors, viz geo-morphology, relief, groundwater fluctuation, rainfall, catchment area and canal–road network density, on water- logging in the north Bihar region of Gangetic Plains. Satellite images IRS P6 LISS III acquired in the years 2005 and 2006 were used to map temporal variability in surface waterlogging which revealed a reduction of 52 % in the waterlogging area during the pre-monsoon. The seasonal groundwater fluctuation was examined using 2005–2006 pre- and post-monsoon water level data. It clearly indicated that a large portion of the area was also under highly critical groundwater level occurring at a depth of less than 1 m belowground surface during the post-monsoon periods. The percentage of waterlogged area per square kilometer in each geomorphological unit clearly depicts that the Kosi mega- fan (Lower), because of a high density of paleochannels, comprises the highest post-monsoon waterlogged area. The Tropical Rainfall Measuring Mission (TRMM) data were analyzed for the period 1998–2009 to examine the spatial variability of rainfall over the entire catchment during the monsoon period. The high incidence of post-monsoon surface waterlogging delineated through satellite data and high average rainfall ([1,100 mm) in the same area indicates a positive relationship between rainfall and surface waterlogging. Waterlogging is more prominent in the lower relief zones, but anomalous relative rise in waterlogging within 40–50 m of relief zone was attributed to anthropo- genic factors primarily related to the development of canal network.

Also, a graph of overall accuracy versus cut value is proposed to determine the change in the behavior of the logistic regression model with varying probability threshold. The optimum cut of value for logistic regression model for the considered parameters was examined. Despite its inability to deal with the temporal dynamics, logistic regression is an empirical formula based robust method for modeling the unplanned urban growth, especially for developing countries like India where the growth is desultory.

Management of floods and waterlogging hazards in highly flood-prone regions of India, including Bihar state has been largely response oriented with little or no attention to mitigation and preparedness. This paper presents a method for spatial, Geographic Information Systems-based assessment of flood and waterlogging vulnerability and risk in northern Bihar plains. Multi- temporal satellite data was used to evaluate the area statistics and dynamics of waterlogging over the period from 1975 to 2008. The flood proneness is evaluated at district level with reference to flood inundation during a period from 1998 to 2008. Census data were used to examine the socio-economic characteristics of the region through computation of population density, cultivators, agricultural labourers, sex ratio, children in age group 0–6 years and literates. The geohazard map derived by combining area prone to waterlogging and flood inundation was multiplied with socio-economic vulnerability map to derive the flood-waterlogging risk map of the region. The result shows that flood and water-logging pose highest risk to the central districts in the northern Bihar plains with 50.95% of the total area under high and very high risk.

At the same time land degradation because of desertification, soil salinity, waterlogging, floods/droughts, excessive soil erosion and unscientific agricultural practices has resulted in the creation of vast stretches of wastelands. This has necessitated adoption of scientific measures for increasing land productivity and bringing more areas under cultivation/forests. In the present study, the multi#temporal satellite images of IRS P6 LISS#III were used to map wastelands dynamics over different seasons. An attempt has also been made to evaluate the potential of high spatial resolution LISS IV (5.8 m) data over moderate spatial resolution LISS#III data (23.5 m) from the Indian Remote Sensing Satellite for delineation of wastelands in a portion of the Indo#Gangetic plains of northern India. Visual interpretation based on image characteristics and a prior knowledge of the study area was used to delineate wasteland classes. Using LISS III data, 1372.92 and 605.90 hectares of land areas are identified as affected by seasonal and permanent waterlogged respectively, and using LISS IV, 1113.33 and 105.84 hectares of land areas are identified as affected by seasonal and permanent waterlogged respectively. Wasteland classes such as seasonal and permanent waterlogged could be further separated into wasteland classes such as land with dense scrub, land with open scrub, degraded pastures/grazing lands and degraded land under plantation using higher resolution satellite data.

The main objective of the present investigation is to identify and map the surface extent of salt affected and waterlogged areas during pre-monsoon and post-monsoon season using multi-temporal satellite images and its relationship with soil, rainfall, seasonal groundwater fluctuation and canal command areas. For this purpose, Satellite images from IRS P6, LlSS-III sensor, on a scale of 1:50,000 have been used for delineation of thematic layers such as salt affected and waterlogged areas. The area covered under post monsoon waterlogging (seasonal) comprised of as 114.79 sq km area which is 3.60% of the study area whereas post monsoon waterlogging (permanent) comprised of 89.37 sq km area, which is 2.80% of the study area. The map depicting salt affected soils in the area indicates calcareous fine loamy, coarse-loamy, fine loamy and very fine soil comprising 2799.43 sq km, 9.26 sq km 363.73 sq km and 2.80 sq km area respectively. The monthly TRMM 3B43 rainfall data for the period of 1998-2009 covering the month of June to September shows rainfall varies from less than 965 mm to 1165 mm in the entire state. Depth to groundwater level recorded at select locations by Central Ground Water Board (CGWB), Government of India, for the period 2004-2005 during pre and post monsoon period indicated that a large portion of the area is under groundwater induced waterlogging conditions where groundwater occurs at a depth of 0-3 m below ground surface. The soil and rainfall map clearly specifies that salinity are pre dominant in areas with shallow groundwater levels and high rainfall. Canal command areas comprised the highest waterlogging and salt affected areas in their vicinity as a result of seepage and over irrigation.

The study analyzed the magnitude and direction of temporal LULC changes for two consecutive periods; 1989–2009. The temporal change patterns of LULC were analyzed through interpretation of LANDSAT imagery. Final land cover maps produced under four major classes after a supervised (maximum likelihood) classification exercise. Results of the study revealed that the study area has undergone substantial LULC changes, primarily a shift from natural cover into managed agro-systems which is apparently attributed to the increasing both human and livestock pressure. This shows that, most of the previously forest covered and grass lands are shifted to the rapidly expanding farm land use classes. The findings of this study suggested that the rate of LULC change over the study period, particularly deforestation due to the expansion of farm land and soil erosion problems need to be given due attention to maintain the stability of the ecosystem.

The comparison of Landuse/land cover classes from 1992-2009 indicates major increase in agricultural land (+115.14% in 2002 and +109.61% in 2009) and built up (+105.49%, in 2002 and 105.73% in 2009) classes with respect to area coverage in Harmu watershed whereas, the area of scrub land (-5.88 in 2002 and -42.95), open forest (-16.39% in 2002 and -80.4% in 2009) and wasteland (-22.56% in 2002 and -27.24% in 2009) classes has decreased. The substantial decrease in wasteland during the period could be attributed to the implementation of government wasteland reclamation measures. The pollution level of Harmu river is high at all sites due to the regular discharge of domestic sewage, disposal of automobile/ workshop waste, increasing settlement nearby the river and garbage which led to water not suitable for drinking as well as for domestic purpose. It was observed that the river/drainage channels were primarily encroached by built up land and few of the drainage channels were extinct due to urban activities.

In the course of recent decades, the quantity of Asian Elephants has dwindled because of human infringement and spontaneous settlements and development along the development courses and halls of this lofty creature. Along these lines, legitimate preservation activities require a point by point spatial database on the courses and passages of Asian Elephant. Human- natural life clashes happen inside the setting of dynamic socio-environmental frameworks. Understanding these contentions at generally more extensive spatial and transient scales gives a knowledge into the contention situations crosswise over bigger territory and changes in their spread and power over a wide time frame. This information would be able to give vigorous contributions to arrangement making for the locale on the issue. Then again, understanding these contentions at generally littler spatio-fleeting scale may be helpful in moderation of contentions for neighbourhood administration organizations, for example, Forest Department. This locale is much of the time left by elephants from the neighbouring environments of Orissa and Jharkhand looking for better natural surroundings and regularly entering human residences and farming fields bringing about clashes with people. Satellite images and ground data were utilized for Land use/land cover mapping and identification of contention zones. In the present study, data was utilized to dole out weights to the three elements, viz., types of vegetation cover , nearness to water body, and vicinity to human home. In light of the investigation, a passageway for elephant development and movement has been recognized which could be overseen by the state government with a specific end goal to limit human-elephant clashes in the locale.

The present study pertains to the evaluation of control exerted by various factors, viz geo-morphology, relief, groundwater fluctuation, rainfall, catchment area and canal–road network density, on water- logging in the north Bihar region of Gangetic Plains. Satellite images IRS P6 LISS III acquired in the years 2005 and 2006 were used to map temporal variability in surface waterlogging which revealed a reduction of 52 % in the waterlogging area during the pre-monsoon. The seasonal groundwater fluctuation was examined using 2005–2006 pre- and post-monsoon water level data. It clearly indicated that a large portion of the area was also under highly critical groundwater level occurring at a depth of less than 1 m belowground surface during the post-monsoon periods. The percentage of waterlogged area per square kilometer in each geomorphological unit clearly depicts that the Kosi mega- fan (Lower), because of a high density of paleochannels, comprises the highest post-monsoon waterlogged area. The Tropical Rainfall Measuring Mission (TRMM) data were analyzed for the period 1998–2009 to examine the spatial variability of rainfall over the entire catchment during the monsoon period. The high incidence of post-monsoon surface waterlogging delineated through satellite data and high average rainfall ([1,100 mm) in the same area indicates a positive relationship between rainfall and surface waterlogging. Waterlogging is more prominent in the lower relief zones, but anomalous relative rise in waterlogging within 40–50 m of relief zone was attributed to anthropo- genic factors primarily related to the development of canal network.
