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 Impact

The Amrit Mahal Kaval grassland is a protected area dedicated to conservation of Amrit Mahal, an endangered breed of cattle that originated from the erstwhile state of Mysore in Karnataka. Nearly 14519 acres of grassland is reserved which is enriched with biodiversity and grassland ecosystem as well and with over 450 years of history. Thus, such kind of research on grasslands is important and also inevitable. Another important point to be noticed is that, this area was portrayed as barren land and in the year 2007, a report was prepared and submitted to the state government permitting Defense and other departments to use these 11400 acres of Amrit Mahal Kaval Grasslands which led to several impact on the biodiversity in this area. Remote sensing and GIS technologies were used to study the impact on grasslands in terms of Social, Cultural, Economic and Environmental changes between 2009 to 2019. By looking at the statistics of the Challakere Amrit Mahal Kaval grasslands it is evident that the developmental work carried out here has led to the loss of 4.59% of the vegetation area, 0.29% of the water sources and 24.6% of the pasture land. The Study focuses not only on the impact of biodiversity in that area but also on the social life of people. In today’s condition both development and ecological balance are important but at the same time it is really hazardous to suppress ecology in the name of development. Compromising ecology for development is proven inimical. It is the need of the hour to protect Amrit Mahal Kaval grasslands as it provides an important habitat for many endangered species like the Great Indian Bustard and Amrit Mahal cattle breed.

An endeavor is created to think about the importance of morphometry, incorporating RS information and strategies notwithstanding the ordinary techniques in a GIS stage. A morphometric evaluation of Tamiraparanisubbasin was completed to decide the seepage attributes utilizing GIS system. The examination has exhibited the potential utilization of the remotely detected information and the GIS in assessment of linear, relief and areal morphometric metrics. By breaking down their impact on the origin and procedures of landforms and qualities of soil metrics like surface, waste and land erosion circumstances. The visual translation of satellite information is utilized for dissecting the topographical, landforms and land erosion attributes in conjunction with seepage design encourages powerful depiction of particular features to assess the impact of drainage morphometry. After the execution, the model gives a seepage bowl Strahler's network stream organize upheld by topical layers like perspective, incline, help, and seepage mass. The proposed design uncovers the waste region of this hub is 734.84 km2 and presents subdendritic to dendritic seepage design. The bowl incorporates seventh request stream and for the most part commanded by bring down stream pattern. The bowl incorporates seventh request stream and generally commanded by bring down stream arrange. The slant of the investigation region shifts from 0 in the east to 61 tin the direction opposite to East. The nearness of WG is the head regulatory element for the slant variety. Besides, the slant variety is controlled by the nearby lithology and erosion cycles. The bifurcation proportion shows that the topographical assembly has small effect on the waste systems and the seepage mass uncovers the idea of subsurface strata is porous.
