Improving On Farm Agricultural Water Productivity In The Karkheh River Basin Research Report No 2 Proceedings Of The International Workshop Improving Water Productivity And Livelihood Resilience In Karkheh River Basin Iran 10 11 Sep 2007

The Nile is the world's longest river and sustains the livelihoods of millions of people across ten countries in Africa. This book provides unique and up-to-date insights on agriculture, water resources, governance, poverty, productivity, upstream-downstream linkages, innovations, future plans and their implications.

Coastal deltas represent one of the most diverse biophysical regions in the tropical developing world. These regions are also home to large human populations and are significant areas of agricultural production and industrialization. Tropical deltas currently face a number of environmental pressures stemming from their intensive use and rapid development, and new threts are emerging as a result of global climate change and expected sea-level rise. Focusing on the developing countries of Asia, Africa and South America, chapters explore the impact of development strategies and existing land and water management practices on delta environments. New management techniques are also explored, which address conflicts between rice-based agriculture, aquaculture, fisheries, and the emerging threat of climate change. Illustrating the current key management challenges involved in protecting tropical deltaic systems in the face of environmental change, this book will be an essential reference for students, researchers and policy makers in agriculture, environmental science and aquaculture.

The Ganges is one of the most complex yet fascinating river systems in the world. The basin is characterized by a high degree of heterogeneity from climatic, hydrological, geomorphological, cultural, environmental and socio-economic perspectives. More than 500 million people are directly or indirectly dependent upon the Ganges River Basin, which spans China, Nepal, India and Bangladesh. While there are many books covering one aspect of the Ganges, ranging from hydrology to cultural significance, this book is unique in presenting a comprehensive inter-disciplinary overview of the key issues and challenges facing the region. Contributors from the three main riparian nations assess the status and trends of water resources, including the Himalayas, groundwater, pollution, floods, drought and climate change. They describe livelihood systems in the basin, and the social, economic, geopolitical and institutional constraints, including transboundary disputes, to achieving productive, sustainable and equitable water access. Management of the main water-use sectors and their inter-linkages are reviewed, as well as the sustainability and trade-offs in conservation of natural systems and resource development such as for hydropower or agriculture.

This unique book addresses Iran’s extremely rich soil diversity and resources, which have developed under various climatic conditions ranging from dry to humid conditions. Featuring contributions by a group of respected experts on Iranian soils and agriculture, it provides comprehensive information on the management approaches needed for sustainable soil utilization and conservation under such conditions, and the attendant challenges. As such, it offers a valuable resource for anyone interested in soils and agriculture in Iran, but also in other Middle East and North African countries with similar climatic conditions. The book contains 14 chapters which illustrate the long history of indigenous knowledge and soil research, climate, geology and geomorphology, vegetation cover, soil forming factors and processes, major soils, properties and their classification. Furthermore, it presents past climate change and paleosols, agroecological zones, soil fertility, soil biology and biotechnology, human induced land degradation and “soil management in space and time”. In the end, major challenges facing the soil resources of the country are defined and recommendations are made to face the future challenges.

This book highlights recent efforts to sustain agricultural productivity in Tunisia under a stressed environment and aridity conditions. This book's authors gathered a unique set of applications and approaches, including techniques applied to increase yield and preserve the environment, such as organic farming and using biochar amendment and its effects on soils' physicochemical properties. This book also presents water resources management and water management practices for sustainable soil production, diagnosis, and new farming technologies to enhance water-use efficiency. The book also addresses current livestock strategies intended to maintain production sustainability, increase fish productivity, and initiatives for sustainable tourism development. Given its scope, the book offers a valuable guide for policy planners, decision-makers, stakeholders, researchers, and graduate students in Tunisia and neighboring countries with similarly stressed environmental conditions.

WATER, CLIMATE CHANGE, AND SUSTAINABILITY An in-depth review of sustainable concepts in water resources management under climate change Climate change continues to intensify existing pressures in water resources management, such as rapid population growth, land use changes, pollution, damming of rivers, and many others. Securing a reliable water supply—critical for achieving Sustainable Development Goals (SDGs)—requires understanding of the relation between finite water resources, climate variability/change, and various elements of sustainability. Water, Climate Change, and Sustainability is a timely and in-depth examination of the concept of sustainability as it relates to water resources management in the context of climate change risks. Featuring contributions by global authors, this edited volume is organized into three sections: Sustainability Concepts; Sustainability Approaches, Tools, and Techniques; and Sustainability in Practice. Detailed chapters describe the linkage between water and sustainable development, highlight the development and use of new measuring and reporting methods, and discuss the implementation of sustainability concepts in various water use sectors. Topics include localizing and mainstreaming global water sustainability initiatives, resilient water infrastructure for poverty reduction, urban water security for sustainable cities, climate actions and challenges for sustainable ecosystem services, and more. This important resource: Reviews contemporary scientific research and practical applications in the areas of water, climate change and sustainability in different regions of the world Discusses future directions of research and practices in relation to expected patterns of climate changes Covers a wide range of concepts, theories, and perspectives of sustainable development of water resources Features case studies of field and modelling techniques for analyzing water resources and evaluating vulnerability, security, and associated risks Discusses practical applications of water resources in contexts such as food security, global health, clean energy, and climate action Water, Climate Change, and Sustainability is an invaluable resource for policy makers water managers, researchers, and other professionals in the field, and an ideal text for graduate students in hydrogeology, climate change, geophysics, geochemistry, geography, water resources, and environmental science.
