Book Synopsis Soil Health Restoration and Management by : Ram Swaroop Meena
Download or read book Soil Health Restoration and Management written by Ram Swaroop Meena and published by Springer Nature. This book was released on 2019-08-23 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meeting the food requirements of an ever-increasing population is a pressing challenge for every country around the globe. Soil degradation has a negative impact on food security by reducing the cultivated land areas, while at the same time the world population is predicted to increase to 9.2 billion in 2050. Soil degradation adversely affects soil function and productivity and degraded soils now amount to 6 billion ha worldwide. The major factors are salinization, erosion, depletion of nutrients due to exhaustive agricultural practices and contamination with toxic metal ions and agrochemicals, which reduces the activity of soil microbe. In addition, poor soil management also decreases fertility. As such, measures are required to restore the soil health and productivity: organic matter, beneficial microorganisms and nutrient dynamics can all improve the physical, chemical and biological properties of soil. Understanding the role of soil health restoration and management in sustainability and nutritional security calls for a holistic approach to assess soil functions and examine the contributions of a particular management system within a defined timescale. Further, best management practices in cropping systems are important in ensuring sustainability and food and nutritional security without compromising the soil quality and productivity potential. Rational soil management practices must allow environmentally and economically sustainable yields and restoration of soil health.
Book Synopsis Effects of Preferential Flow Paths and Land Use on Hydrological Behaviors in Tropical Catchments by : Cheng Yanyan

This book was released on 2018 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this Ph.D. research is to better understand the effects of land use/land cover changes (LUCC) on hydrologic behaviors at watershed scale in humid seasonal tropics. Modeling and data analysis approaches were used in three parts. First, a physically-based, distributed model with four different model structures without and with preferential flow paths (PFPs) is developed to investigate the role of PFPs in steep, humid, tropical lowland catchments in the Panama Canal Watershed (PCW). Simple model structures are judged implausible based on a Nash-Sutcliffe criterion. The model structure with explicit simulation of PFPs performs the best, which clearly demonstrates the need to include PFPs that are historically underappreciated in hydrological modeling. Second, the effect of land covers on the formation of PFPs is incorporated into the proposed process-based hydrological model to address the underlying mechanism of hydrological responses due to LUCC. Results show that differences in PFP parameters attributable to LUCC can explain the mechanism of the “forest sponge effect”, wherein forested catchments produce more baseflow during long dry periods than pastured catchments. The effects of LUCC on PFPs can also explain land use dependent differences in peak flows and runoff ratios. Finally, a new approach is proposed to examine a unique but poorly understood step-wise increase in baseflow, using data from seven watersheds in the PCW. The extent to which the observed baseflow jump phenomenon can be attributed to rainfall characteristics and categorical catchment attributes (e.g., land cover, area, and slope) is explored. This approach aids in detecting key signals in observed discharge data. Together with the modeling efforts, it can significantly advance understanding of the role of PFPs and LUCC in shaping hydrological responses of the tropical catchments, with implications in land management to enhance hydrologic ecosystem services in humid tropical ecosystems.
Book Synopsis Land Ocean Interaction by : D. Huntley
Download or read book Land Ocean Interaction written by D. Huntley and published by IWA Publishing. This book was released on 2000-12-01 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The UK Land-Ocean Interaction Study (LOIS) provided a major opportunity to measure and model the processes controlling the fluxes of materials between river basins and coastal seas. The main programme of research took place between 1992 and 1998, funded by the UK Natural Environment Research Council, and involved approximately 360 coastal researchers contributing to more than 70 collaborative projects. This book presents accessible summaries of key results of this research. The ten chapters of the book are written by leading contributors to the programme, and cover aspects of the physical, sedimentological, chemical and biological processes controlling fluxes between river catchments and coastal seas in temporate environments. Major overarching themes for all of the chapters include the persistence, storage, degradation and transport of pollutants from catchment to coastal sea, and an emphasis on the relevance of research for river and coastal water quality management. The chapters also describe a number of important technological advances in the measurement of processes and longer term monitoring of the fluvial, estuarine and coastal environments. Approaches to monitoring were also transferred between disciplines, in many cases for the first time. The rivers and coastal programme of LOIS was unique in its scale and inter-disciplinarity and its results are of lasting value. This book provides a useful and important summary of many of its results and an effective introduction to the research for those who want to delve more deeply into the data and published papers. It will be of interest to scientists, environmental managers and scientific policy makers.

Book Synopsis Clean Coastal Waters by : National Research Council
Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-08-17 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

Book Synopsis Geomorphology in the Anthropocene by : Andrew S. Goudie
Download or read book Geomorphology in the Anthropocene written by Andrew S. Goudie and published by Cambridge University Press. This book was released on 2016-10-10 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Anthropocene is a major new concept in the Earth sciences and this book examines the effects on geomorphology within this period. Drawing examples from many different global environments, this comprehensive volume demonstrates that human impact on landforms and land-forming processes is profound, due to various driving forces, including: use of fire; extinction of fauna; development of agriculture, urbanisation, and globalisation; and new methods of harnessing energy. The book explores the ways in which future climate change due to anthropogenic causes may further magnify effects on geomorphology, with respect to future hazards such as floods and landslides, the state of the cryosphere, and sea level. The book concludes with a consideration of the ways in which landforms are now being managed and protected. Covering all major aspects of geomorphology, this book is ideal for undergraduate and graduate students studying geomorphology, environmental science and physical geography, and for all researchers of geomorphology.
