Book Synopsis Spatial Techniques for Soil Erosion Estimation by : Rupesh Jayaram Patil
Download or read book Spatial Techniques for Soil Erosion Estimation written by Rupesh Jayaram Patil and published by Springer. This book was released on 2018-02-06 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a novel computation of the topographic LS factor of the USLE model to estimate spatial soil erosion. In developing countries, soil erosion is one of the main concerns as it adversely affects agriculture and reduces food production. Therefore, the author presents a particularly relevant approach, as he demonstrates how the C++ programming allows us to identify important erosion stages like detachment and deposition. He does this by assessing the annual rate of soil erosion from the Shakkar River watershed in India using distributed information and applying RS and GIS techniques. He also discusses different approaches that have been proposed to work out the influence of topography on erosion. Simulated and observed data of sediment loss are compared for the period 1992 to 2006.This book provides an easy-to-understand basic piece of soil erosion and hydrological research and reaches out to young researchers and students at the graduate and undergraduate level as well as applicants of soil erosion models.

This book was released on 2014-06-25 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main thought of this work is to recommend the method of estimating soil erosion and prioritization of watersheds where data availability is major concern. In these circumstances, the use latest technologies such as remote sensing and GIS plays crucial role. The main advantages of these technologies are that, it provides accurate information and that to from any part of the area under investigation. This work was carried out by author for fulfillment of M.Tech degree from IIT Kharagpur, INDIA. The study mainly focuses on application of most widely used Universal Soil Loss Equation (USLE) to predict soil erosion hazard in the Upper Damodar Valley Catchment (UDVC) of India. Micro-watershed wise soil loss was estimated and prioritization of micro watersheds was done with the help of annual average R factor obtained from 9 years rainfall data. Other factors viz. K, LS and CP were used for this analysis. The treatment plan for controlling soil erosion is also suggested at micro watershed level. Remote sensing and GIS techniques were applied to prepare various layers of USLE parameters which interactively estimate soil erosion at micro watershed level.

Book Synopsis A Geoinformatics Approach to Water Erosion by : Tal Svoray
Download or read book A Geoinformatics Approach to Water Erosion written by Tal Svoray and published by Springer Nature. This book was released on 2022-02-17 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Degradation of agricultural catchments due to water erosion is a major environmental threat at the global scale, with long-lasting destructive consequences valued at tens of billions of dollars per annum. Eroded soils lead to reduced crop yields and deprived agroecosystem’s functioning through, for example, decreased water holding capacity, poor aeration, scarce microbial activity, and loose soil structure. This can result in reduced carbon sequestration, limited nutrient cycling, contamination of water bodies due to eutrophication, low protection from floods and poor attention restoration—consequences that go far beyond the commonly modelled soil loss and deposition budgets. This book demonstrates, using data from the Harod catchment in northern Israel, how cutting-edge geoinformatics, data science methodologies and soil health indicators can be used to measure, predict, and regulate these major environmental hazards. It shows how these approaches are used to quantify—in time and space—the effect of water erosion not only on the soil layer, soil minerals, and soil loss, but also on the wide-range of services that agricultural ecosystems might supply for the benefit and well-being of humans. The algorithms described in this book play a major role in this paradigm shift and they include, for example, extraction of photogrammetric DEMs from drone's data, advanced drainage structure calculations, fuzzy process-based modelling and spatial topographic threshold computations, multicriteria analyses and expert-based systems development using analytic hierarchal processes, innovative data-mining and machine learning tools, autocorrelation and interpolation of soil health, physically-based soil evolution models, spatial decision support systems and many more.

Book Synopsis Climate Change Impact on Soil Erosion in Sub-tropical Environment by : Subodh Chandra Pal
Download or read book Climate Change Impact on Soil Erosion in Sub-tropical Environment written by Subodh Chandra Pal and published by Springer Nature. This book was released on 2022-11-02 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work focuses on the potential impact of climate change on soil erosion in a monsoon-dominated sub-tropical region. Water-induced soil erosion due to extreme rainfall during the monsoon period is a major problem worldwide, from different environmental and socio-economic perspectives. This study region covered (South Bengal) is one of the fertile agricultural belts that produces a good amount of produce and contributes to the country's GDP. However, the rate of agricultural output has decreased rapidly in recent times due to a decline in soil fertility. The monsoon-dominated sub-tropical region has unique characteristics in terms of seasonal temperature fluctuations and the availability of rainfall events. The sub-tropical region is densely populated, with the majority of the population relying on rain-fed agricultural production systems. The declining rate of agricultural production has also established that soil fertility is declining and soil erosion is increasing. Numerous studies show that soil erosion is the major cause of the region's rapidly increasing trend of land degradation. A homeostatic mechanism cannot replace soil erosion, and a gap arises between soil erosion and regolith formation. Extreme changes in land use and land cover, population growth and the lacking support for traditional agricultural practices and management practices can accelerate the rate of soil erosion and its associated reservoir sedimentation in most countries of the tropical and sub-tropical environment. Quantitative information with maximum possible accuracy through validation regarding soil loss can be an essential part of the appropriate and sustainable soil and water conservation planning. The precise aspects of modern day management strategies are soil erosion susceptibility mapping using empirical and semi-empirical models in a GIS platform or the use of probability statistics. The main objective of this work is to propose the most suitable development strategies considering the amount of soil erosion for the present and future periods. Extensive field research has been done to identify the support practice factor that the local stakeholders adopt in this region.

MODELLING SOIL EROSION BY WATER l 2 John Boardman and David Favis-Mortlock 1 School of Geography and Environmental Change Unit Mansfield Road University of Oxford Oxford OX1 3TB UK 2 Environmental Change Unit University of Oxford 5 South Parks Road Oxford OX1 3UB UK Introduction This volume is the Proceedings of the NATO Advanced Research Workshop 'Global Change: Modelling Soil Erosion by Water', which was held on II-14th September 1995, at the University of Oxford, UK. The meeting was also one of a series organised by the IGBP 1 GCTE Soil Erosion Network, which is a component of GCTE's Land Degradation Task (3.3.2) (Ingram et aI., 1996; Valentin, this volume). One aim of the GCTE Soil Erosion Network is to evaluate the suitability of existing soil erosion models for predicting the possible impacts of global change upon soil erosion. Due to the wide range of erosion models currently, in use or under development, it was decided to evaluate models in the following sequence Favis-Mortlock et al., 1996): • field-scale water erosion models • catchmenr-scale water erosion models • wind erosion models • models with a landscape-scale and larger focus. As part of this strategy, the first stage of the GCTE validation of field-scale erosion models was carried out at the Oxford NATO-ARW. I A list of Acronyms fonns Appendix A.
Book Synopsis Soil Degradation and Restoration in Africa by : Rattan Lal
Download or read book Soil Degradation and Restoration in Africa written by Rattan Lal and published by CRC Press. This book was released on 2019-07-09 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil degradation is a widespread problem in Africa resulting in decreased agricultural productivity while demand for food continues to increase. Degradation is caused by accelerated erosion, acidification, contamination, depletion of soil organic matter and plant nutrients, and salinization. The major cause of soil degradation in Africa is uncontrolled and excessive grazing in the savanna regions followed by deforestation and the use of inappropriate and extractive farming practices. Perpetual neglect of the health of soils in Africa can exacerbate the already serious problems of food and nutritional insecurity and environmental degradation. Food and nutritional security of the growing population of Africa can only be achieved if degraded soils are restored and soils of agroecosystems are managed prudently and sustainably. Ignoring soils and taking the fragile, finite and precious soil resources for granted is the principal cause of poverty, hunger, and environmental degradation. The downward spiral must be reversed through soil restoration measures based on translating science into action. This book describes the soils of Africa, processes of soil degradation, extent and severity of soil degradation, and the impacts of degradation processes on food and nutritional security. Features: Explores the extent and severity of soil degradation in Africa Analyzes the cause–effect relationship between anthropogenic activities and soil degradation Reviews processes of soil degradation in Africa including erosion, salinization, nutrient depletion, and decline of soil organic matter Addresses the effect of climate change on soil degradation in Africa. Explains how soil degradation causes food and nutritional insecurity Part of the Advances in Soil Sciences series, this volume is specifically devoted to the processes and factors that cause soil degradation and the challenges and potential for remediation and restoration of soil health in Africa.
Book Synopsis Assessment of Erosion Vulnerable Area Using Gis and Remote Sensing by : Abebe Mengaw
Download or read book Assessment of Erosion Vulnerable Area Using Gis and Remote Sensing written by Abebe Mengaw and published by LAP Lambert Academic Publishing. This book was released on 2012-06 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil degradation in the form of soil erosion is a serious and continuous environmental problem in different part of the world. Uncontrolled land use, deforestation, land over cultivation, overgrazing and exploitation of biomass for firewood, construction and other household uses due to increasing population ultimately leads to severe soil erosion. This study had integrated GIS, RS and MCE models to assess and map erosion vulnerable areas and RUSLE model to quantify an estimated soil loss in Jabi Tehinan Woreda. Slope gradient, soil type, LULC, rainfall and drainage pattern were used as input model parameters/variables. The data had been collected and analyzed from different land sat imageries, SRTM data, topomaps and point interpolations of primary data. Finally the aggregated effects of all parameters had been analyzed and priority rating of erosion vulnerable area was calculated using weighted overlay techniques.
Book Synopsis Geospatial Technologies for Land Degradation Assessment and Management by : R. S. Dwivedi
Download or read book Geospatial Technologies for Land Degradation Assessment and Management written by R. S. Dwivedi and published by CRC Press. This book was released on 2018-10-17 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: The constant growth of the world’s population and the decline of the availability of land and soil resources are global concerns for food security. Other concerns are the decrease in productivity and delivery of essential ecosystems services because of the decline of soil quality and health by a range of degradation processes. Key soil properties like soil bulk density, organic carbon concentration, plant available water capacity, infiltration rate, air porosity at field moisture capacity, and nutrient reserves, are crucial properties for soil functionality which refers to the capacity of soil to perform numerous functions. These functions are difficult to measure directly and are estimated through indices of soil quality and soil health. Soil degradation, its extent and severity, can also be estimated by assessing indices of soil quality and health. "Geospatial Technology for Land Degradation Assessment and Management" uses satellite imagery and remote sensing technologies to measure landscape parameters and terrain attributes. Remote sensing and geospatial technologies are important tools in assessing the extent and the severity of land and soil degradation, their temporal changes, and geospatial distribution in a timely and cost-effective manner. The knowledge presented in the book by Dr. R.S. Dwivedi shows how remote sensing data can be utilized for inventorying, assessing, and monitoring affected ecosystems and how this information can be integrated in the models of different local settings. Through many land degradations studies, land managers, researchers, and policymakers will find practical applications of geospatial technologies and future challenges. The information presented is also relevant to advancing the Sustainable Development Goals of the United Nations towards global food security.
