The Impact

Understanding and identifying the spatial-temporal changes in the natural environment is crucial for monitoring and evaluating conservation efforts, as well as understanding the impact of human activities on natural resources, informing responsible land management, and promoting better decision-making. Conservation areas are often under pressure from expanding farming and related industry, invasive alien vegetation, and an ever-increasing human settlement footprint. This study focuses on detecting changes to the Prince Alfred Hamlet commonage, near Ceres in the Cape Floral Kingdom. It was chosen for its high conservation value and significance as a critical water source area. The study area includes a fast-growing human settlement footprint in a highly productive farming landscape. There are conflicting development needs as well as risks to agricultural production, and both of these threaten the integrity of the ecosystems which supply underlying services to both demands on the land. Using a multi-disciplinary approach and high-resolution satellite imagery, land use and land cover changes can be detected and classified, and the results used to support the conservation of biodiversity and wildlife, and protect our natural resources. The aim of this research is to study the efficacy of using remote sensing and GIS techniques to detect changes to critical conservation areas where disturbances can be understood, and therefore better managed and mitigated before these areas are degraded beyond repair.

The IRS -P6 LISS-IV satellite data is used to demarcate Hydrogeomorphology land forms and lineaments on 1;10000 scale to evaluate groundwater potential of the study area. The Ramannapet Mandal area of Musi river basin is occupied mostly by hard rock they are granites and gneisses of Archaean age with intrusive bodies of dolerites, and of the portion of the study area is covered mainly by both wet and dry cultivation. The major geomorphic unit identified in the area are, Denudational hills, Residual hills, Inselbergs, Dykes, Pediment inselberg complex, Pediment, Pediplain and valleys. Most part of the study area is occupied by Pediplain with various thickness and the groundwater potential is directly related to thickness of Pediplain. The object of the study is Remote Sensing imagery with its synoptic coverage acts as a tool for finding suitable solution when combined with conventional data. Hydro-geomorphic maps were prepared by integrating the Lithology, landforms, and structural fabric and hydrology layers and drainage layers using Remote Sensing and GIS techniques, the scale range of 1: 10,000. The lineament density map was generated in GIS software using Kriging method (Sabins, F. F., (1997). Outcomes of the study Based on visual interpretation and field investigations the different types of hydro geomorphic units observed in the study area. The recent alluvium deposits are present along the stream courses. Field observations shows that groundwater occurs under unconfined conditions with water table shallow to deep depth. from the lineament density and lineament intersection maps prepared to understand the impact on groundwater percolation. Finally, Hydrogeomorphology and lineament maps area overlaid following the weighted index overlay method, which delineate groundwater potential zones. an integrated Remote sensing and GIS based approach has been used for demarcating groundwater potential zones in the study area. The study area Ramannapet Mandal is in northern part of the district of Nalgonda, Telangana State, India. The study area people occupation is agricultural, and poultry, 80 percent of the people depending only agricultural activity
