The papers assembled here cover topics such as technological advances in soil salinity mapping and monitoring, management and reclamation of salt-affected soils, use of marginal quality water for crop production, salt-tolerance mechanisms in plants, biosaline agriculture and agroforestry, microbiological interventions for marginal soils, opportunities and challenges in using marginal waters, and soil and water management in irrigated agriculture.

This volume presents the outcome of an Agriculture Workshop organized by the Gulf Research Centre Cambridge (GRCC) and held at Cambridge University, UK during the Gulf Research Meeting 11-14 July 2012. Co-directed by the editors, the workshop, entitled Environmental Cost and Changing Face of Agriculture in the Gulf States was attended by participants from Australia, Bahrain, India, Kuwait, Oman, Saudi Arabia, Turkey, UAE, UK and Morocco. These scientists, educators, researchers, policy makers and managers share their experience in agriculture in the Gulf States, with the aim of helping to improve agriculture production and thus bridge the gap between local production and the food import.

The papers gathered here were presented at the workshop and have all passed through rigorous peer review by renowned scientists. The diverse papers present various aspects of agriculture production in the evolving face of climate change and dwindling water resources in the region. The book covers topics such as the prospects of agriculture in a changing climate; the potential of climate-smart agriculture; the impact of food prices, income and income distribution on food security; improved efficiency in water use; challenges in using treated wastewater in agriculture; investment in foreign agriculture and agricultural research and development. The papers span the nations of the Gulf Cooperation Council, with specific case studies set in Oman, Bahrain and Kuwait."

As the world's population continues to expand, maintaining and indeed increasing agricultural productivity is more important than ever, though it is also more difficult than ever in the face of changing weather patterns that in some cases are leading to aridity and desertification. The absence of scientific soil inventories, especially in arid areas, leads to mistaken decisions about soil use that, in the end, reduce a region's capacity to feed its population, or to guarantee a clean water supply. Greater efficiency in soil use is possible when these resources are properly classified using international standards. Focusing on arid regions, this volume details soil classification from many countries. It is only once this information is properly assimilated by policymakers it becomes a foundation for informed decisions in land use planning for rational and sustainable uses.

Due to many challenges (i.e. climate change, energy, water and land shortage, high demands on food, land grabbing, etc.), agriculture production potential is expected to be seriously affected; thus, increasing food insecurity and hunger in many already affected regions (especially in Africa). In this context, sustainable agriculture is highly recommended as an eco-system approach where soil, water, plants, environment and living organisms live in harmony. Innovative technologies and research should be developed to ensure sustainable agriculture and productivity using modern irrigation systems, improved varieties, improved soil quality, etc. In the meantime, the preservation of natural environment should be based on resource conservation technologies and best management practices.

"Sustainable Agricultural Development," not only raises the serious ethical and social issues underlying these huge environmental problems, but also aims at presenting successful experiences from all over the world in relation with sustainable farming, sustainable management of water and land resources, and innovative processes in livestock production. It also aims at providing inputs to decision making processes and encouraging the transfer of relevant know-how, technologies and expertise to different countries where similar agro-climatic conditions may exist; thus saving precious resources and promoting sustainable agricultural development as a relevant approach to tackle the food security challenge.

Finally, this book focuses on the paradigmatic and policy dimensions and call for an innovative approach by analyzing the key themes in a complex and interrelated manner.

This book arises from a 2011 international conference entitled Climate Change, Agri-Food, Fisheries and Ecosystems: Reinventing Research, Innovation, and Policy Agendas for an Environmentally and Socially-Balanced Growth (ICCAFFE2011), organized by the North-South Center for Social Sciences (NRCS) in collaboration with the Deutsche Gesellschaft fur Internationale Zusammenarbeit (GIZ) GmbH, Germany and the Institute for Research and Development (IRD), France. Coverage focuses on the agricultural sector and helps improve understanding of the relationships between agriculture and the environment and between human communities and nature, so as to sustainably manage agricultural development. The contributors analyze the interdependence between sustainable agricultural development and environmental, economic and social dynamics; assess the impacts of soil degradation on agricultural productivity; present ways to enhance livestock production and recommend mechanisms for managing links between agro-biodiversity, climate change and livelihoods. Part I examines sustainable agriculture development and environmental, economic and social dynamics, addressing topics such as global climate change, agriculture and challenges including socio-economic factors, adaptation, poverty reduction and water management. Part II covers the impacts of soil degradation on agricultural productivity and discusses the use of expert systems to assess and manage degraded lands, agricultural productivity, land suitability and rehabilitation. Part III focuses on livestock production enhancements, such as feed resources and supplemental feeds for animals and capacity building for women in dairy management. Part IV shares the outcomes of research in agro-biodiversity, climate change and livelihoods, addressing topics such as co-management of forests, carbon consumption models, biodiversity conservation and carbon sequestration and scarce mangrove forests. Current environmental and agro-ecological research focuses on understanding the cause-consequence relationships between specific agricultural practices and land use and the responses at different levels of ecosystems. This book is intended to contribute to this discussion."

Central to human life and civilization, soils are an integral part of the physical and cultural environment. Although we may take them for granted, the rise and fall of civilizations is closely linked with the use and abuse of soil and water resources. It is therefore important to evaluate soils for their quality and link them to appropriate uses and services. This book provides information on soil classification and shows how to key out taxa relevant to UAE soils. The latest soil inventory of United Arab Emirates reveals that a rather uniform looking desert landscape has, in fact, a diversity of subsurface features. These features confirm the soil diversity in terms of classification, chemistry, physics, mineralogy, fertility, suitability for different uses and vulnerability to land degradation. United Arab Emirates Keys to Soil Taxonomy presents information for keying out the soils of the United Arab Emirates into separate classes and provides a guide to associated laboratory methods. The classification used predominantly is extracted from the 11th edition of the USDA-NRCS Keys to Soil Taxonomy, and sections relevant to the soils found in the UAE are included here. Primarily, this key is designed to fit the soil system of the United Arab Emirates. Information not found in the USDA key has been added, including criteria and classes for: 1) differentiating anhydritic soils from gypsic soils, 2) identifying "lithic" subgroups for Aquisalids and Haplosalids, 3) identifying "salidic" subgroups within the great groups of Gypsids, Calcids, Psamments, and Orthents, and 4) incorporation of phases for soil taxa. A subsurface diagnostic horizon and mineralogy class (anhydritic), not reported earlier in the world soil literature and, recently found in the UAE, has also been added to the book. The book also offers a mechanism for updating the current soil surveys, and will facilitate the correlation of soils from new surveys in the UAE. Additionally, it will help the international soil science community to converse about UAE soils, and facilitate comparison to soils of other regions. These linkages allow countries with similar mapping and classification procedures and similar soils to transfer agriculture technology without conducting long-term experiments under similar environmental conditions, especially for Gulf Cooperation Council countries (Bahrain, Kuwait, Qatar, Oman, and Saudi Arabia).
