Book Description
This book combines multidisciplinary studies on the environmental consequences of intensified use of land and water, and the fusion of land to provide food for a growing population. Studies on water, vegetation, and soil are addressed from an environmental management perspective with a special focus on the relation between natural elements and humans. This book considers the essential dynamics of humans and the natural environment, which is especially important in areas with shallow water-table that influence directly on agricultural activities (crops, livestock, and forests), land management, flooding, droughts, waterlogging, salt-affected soils (saline and sodic) and variation in obtained water quality in wells where these processes as related to the local and regional geomorphology control. The studies present hydrological processes towards the definition of an adequate use of soil and water with consequences of its management on the environment. Also, water study procedures are presented as well as their relation to other elements of the landscape. Methodologies such as the Tóthian flow system concept are recognized by different authors to provide the reader with solid interdisciplinary analyses of related environmental components such as soils, vegetation, surface water, geomorphology, geological framework and groundwater physical-chemical composition.

Book Description
There can be little doubt that there are truly colossal challenges associated with providing food, fibre and energy for an expanding world population without further accelerating already rapid rates of biodiversity loss and undermining the ecosystem processes on which we all depend. These challenges are further complicated by rapid changes in climate and its additional direct impacts on agriculture, biodiversity and ecological processes. There are many different viewpoints about the best way to deal with the myriad issues associated with land use intensification and this book canvasses a number of these from different parts of the tropical and temperate world. Chapters focus on whether science can suggest new and improved approaches to reducing the conflict between productive land use and biodiversity conservation. Who should read this book? Policy makers in regional, state and federal governments, as well as scientists and the interested lay public.

Book Description
This book discusses the detrimental consequences of climate-related land changes over a 40-year period between 1981 and 2020, and focuses on how climate warming is deteriorating the agricultural system due to excessive heat, lack of moisture and more intensive and widespread droughts leading to a reduction of agricultural production. Most of the existing literature on the unfavourable consequences of global warming for land are based on a relatively short period of weather station data, covering local land areas with limited networks and monitoring parameters. These concerns have led to the use of satellite data, whose measurements are controlled by such vegetation characteristics as chlorophyll, carotenoids, moisture contents in the plants and temperature inside the vegetation community. Therefore, the discussion of this book is completely based on high-resolution global land surface measurements by the sensors on the National Oceanic and Atmospheric Administration’s (NOAA) operational afternoon polar-orbiting satellites. The book also focuses on understanding climate change impacts on land changes where humans are living, and combines biophysically-grounded methods and the 40-year data to develop models for monitoring large-scale Earth warming impacts on land and for timely prediction of climate consequences for humans. These 40-year trends in land characteristics will help to better inform the assessment of potential changes in the future and how to reach human sustainability. The book will of interest to scientists using satellite remote sensing to track climate change impacts on land over time, as well as students and researchers in climatology and environmental sustainability.

Book Description
Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Book Description
Balancing Water for Humans and Nature, authored by two of the world's leading experts on water management, examines water flows - the 'blood stream' of both nature and society - in terms of the crucial links, balances, conflicts and trade-offs between human and environmental needs. The authors argue that a sustainable future depends fundamentally on our ability to manage these trade-offs and encourage long-term resilience. They advocate an ecohydrological approach to land/water/environmental problems and advance a strong, reasoned argument for viewing precipitation as the gross fresh water resource, ultimately responsible for sustaining all terrestrial and aquatic ecosystem services. This book makes the most coherent and holistic argument to date for a new ecological approach to understanding and managing water resources for the benefit of all. Basing their analysis on per capita needs for an acceptable nutritional diet, the authors analyse predictions of the amounts of water needed for global food production by 2050 and identify potential sources. Drawing on small-scale experiences in Africa and Asia, they also cover the vulnerability of the semi-arid tropics through a simplified model of green and blue water scarcity components.

Book Description
The privatization of water supply and wastewater systems, together with institutional restructuring of governance – through decentralization and the penetration of global firms in local and regional markets – have been promoted as solutions to increase economic efficiency and achieve universal water supply and sanitation coverage. Yet a significant share of service provision and water resources development remains the responsibility of public authorities. The chapters in this book – with case evidence from Argentina, Chile, France, the USA, and other countries – address critical questions that dominate the international agenda on public versus private utilities, service provision, regulations, and resource development. This book presents varied perspectives – largely complementary but at times contrasting – on public and private governance of water. Public authority in general is being reasserted over service provision, while resource development and investments in infrastructure continue as a mix of public and private initiatives. But more important, increased oversight and regulation of market-based initiatives that until recently were touted as panaceas for water supply and sanitation are increasingly being reconsidered on the basis of social equity, environmental, and public health concerns. This book was based on the special issue of Water International.

Book Description
Rainforests are rapidly being cleared in the humid tropics to keep pace with food demands, economic needs, and population growth. Without proper management, these forests and other natural resources will be seriously depleted within the next 50 years. Sustainable Agriculture and the Environment in the Humid Tropics provides critically needed direction for developing strategies that both mitigate land degradation, deforestation, and biological resource losses and help the economic status of tropical countries through promotion of sustainable agricultural practices. The book includes: A practical discussion of 12 major land use options for boosting food production and enhancing local economies while protecting the natural resource base. Recommendations for developing technologies needed for sustainable agriculture. A strategy for changing policies that discourage conserving and managing natural resources and biodiversity. Detailed reports on agriculture and deforestation in seven tropical countries.

Book Description
There are still insufficient general theories on the law of diminishing returns, despite 100 years of development. Starting with intensive variables theory, and by utilizing tools of spatiotemporal correlation and intensive functions, moving on to the integrated curve of diminishing returns and intensive theory, and even more importantly, using a combination of static and dynamic GIS, and integrating numerical calculation and spatial optimization, this book not only creates a unique theoretical framework and methodology for the evaluation of land use effect, but also addresses the long-standing lack of universal theories and methods on the law of diminishing returns. It will have far-reaching impacts on the development of this area and its practical application. The book covers a wide range fields in geography, land science, geographic information science, management science and related areas. Novel theoretical perspectives illustrated with many detailed case studies offer an easier way for readers to expand their research, ensuring that both academic and business audiences will benefit. Prof. Xinqi Zheng works at the China University of Geosciences (Beijing), People’s Republic of China.
