Transformations in the Land systems are the result of human interactions with the natural environment. Land Use-Land Cover changes is the central to debate of sustainable development because it has been considering one of driving force of global change that directly affect the status and integrity of ecosystems The urban intensification that has been occurring from the past few decades accompanied in large consumption of resources, habitat fragmentation, loss of green cover and encroachment of water bodies, open land etc. The present study mainly focuses on identifying LULC changes occurring at west zone of Hyderabad in the span of 1991 to 2018 using remote sensing and GIS technology. Maps were developed using Landsat images from USGS Earth Explorer. Image pre-processing and classification technologies were employed and accuracy assessment has performed to validate the output. The obtained accuracy is between 85 to 100 percent for the all classes. Transformation studies show that the open land has been reduced by 36.07% and urban land has increased by 120.85%, vegetation has decreased by 22.55% and water bodies diminished by 20.82 %. These information is useful to the urban planners and local authorities for the sustainable development of urban intensifying cities.

Due to the fact that poor nations are most impacted, it has grown to be a significant worldwide problem. Natural disasters like aridity, droughts, floods, cyclones, and severe rainfall are all likely to have an impact on humans. Water scarcity can be brought on by climate change in some countries through persistent droughts. The rising population will result in a greater demand for water. Cities are becoming more vulnerable to water-related problems as a result of increased urbanization, changing rainfall patterns, and industrialization. The supply and demand of water can be balanced through the implementation of sustainable practices. In the event of future climate change, rainwater harvesting systems offer an alternative source of water and specific adaptation strategies for coping with water scarcity. The adoption of rainwater harvesting systems is discussed in this article as a strategy for climate change.

The Curve Number (CN) is a land-cover index for the given land useland cover class, elevation and soil type to determine the amount of rainfall that infiltrates into the ground and the amount that becomes runoff for a specific storm event (USDA, 1986). Usually the curve number is classified according to the United State land features classification which may not be applicable to the Indian land features. A high curve number means high runoff and low infiltration (urban areas), whereas a low curve number means low runoff and high infiltration (dry soil). In this study, a rainfall map of the study area was prepared by Thiessen polygon method for years 2000-2014 and the rainfall data for daily was obtained from which normal average monthly, yearly was analyzed. Soil maps have been prepared for the watershed. GIS is used to explore spatial patterns of the trends ove...

The two technologies may be connected to form a dynamic system that is incredibly well adapted to the evaluation of environmental conditions through the interrelationships of texture, size, pattern, and process. This perspective has acquired popularity in multiple disciplines. GIS is significantly dependant on processors, particularly for 3D calculations, map rendering, and route calculation whereas DL can process huge amounts of data. DL has received a lot of attention recently as a technology with a plethora of promising results. Furthermore, the growing use of DL methods in a variety of disciplines, including GIS, is evident. This study tries to provide a brief overview of the use of DL methods in GIS. This paper introduces the essent...

The quality of surface and groundwater is currently an important concern with population growth and industrialization. Over exploitation of water resources due to demand is causing the deterioration of surface water and ground water. Periodic water quality testing must be carried out to protect our water resources. The present research analyses the spatial variation of surface water and groundwater in and around the lakes of Hyderabad. Twenty-Seven lakes and their neighboring bore water samples are obtained for water quality monitoring. Samples are evaluated for specific physico-chemical parameters such as pH, Total Dissolved Solids (TDS), Cl, SO4, Na, K, Ca, Mg, and Total Hardness (TH). The spatial variation of water quality parameters for the 27 lakes and groundwater were analysed. Correlation and multiple regression analysis were carried out to determine comparative study of lake and ground wat...
