Deltas of the World

This book provides accurate and integrated information about land resources especially with the accelerated progress of information technology to help Egypt and similar countries to achieve the country sustainable development goals in the field of agriculture and natural resources. The Egyptian National sustainable development plans mainly aim to conserve the arable lands in the Nile Delta and the Nile Valley, in addition to the oases and desert fringes. Moreover, increasing land productivity is a vital national goal for filling the food gap.  Consequently, providing accurate and integrated information about land natural resources using the recent technologies such as satellite data/images and geoinformatics techniques. Such information would be a base for planning, decision making and research needs all over the world due to the importance of Egypt as the biggest and leading country in the MENA regions.

The book provides land natural resources database as a platform, upon which additional thematic information can be added in the future to serve multi approached sustainable development. The book highlights the usage of digital information in monitoring urban planning and encroachment, in addition to soil and land capability classification. Moreover, networks of irrigation/drainages, railways, and utilities are added for a wide management range. Various available information systems were employed to initiate the targeted land resources database (e.g., ArcGIS, ERDAS IMAGINE and ENVI). Data of previous soil survey projects were the basis for the created digital database including High Dam Soil Survey, Soil map of Egypt and Land Master Plane.

The Digital Elevation Model (DEM) was elaborated using SRTM space images, in addition to spot heights and contour lines derived from the topographic maps (scale 1:50,000) produced by the Egyptian Survey Authority (ESA). The resulted thematic layers were incorporated in the created GIS land resources database. 

The book is a unique and a great source of information and knowledge for all researchers around the globe particularly for MENA regions. Researchers, graduate students, the policy planners and decision making will find this book very useful for them. are most people who could benefit from the book. We believe the book will be an added value to the existing information and knowledge.

This book offers a comprehensive and forward‑looking examination of how global warming is reshaping the world’s river deltas, among the most vulnerable yet vital landscapes on Earth. It provides critical insights into the environmental, social, and political challenges faced by deltaic regions as intensifying climate pressures converge on low‑lying coastal areas.

The volume emphasizes the central importance of delta resilience for global climate adaptation and human security, particularly in the context of rising sea levels, extreme weather events, altered hydrological cycles, accelerated land loss, saltwater intrusion, biodiversity decline, and disruptions to food systems.

It covers key thematic areas including deltaic geomorphology, sea‑level rise, salinization, land subsidence, food security, climate‑induced migration, urban infrastructure risk, and the role of traditional knowledge in adaptation. In‑depth case studies from major delta systems, such as the Mekong, Nile, Ganges‑Brahmaputra, and Mississippi, highlight both shared vulnerabilities and region‑specific dynamics. It also examines governance challenges, financing mechanisms, and international cooperation in managing transboundary river systems, while assessing nature‑based solutions, managed retreat, and emerging adaptation technologies. By bringing together expert perspectives and evidence‑based research, it fills critical knowledge gaps and offers a clear roadmap for policy and future action.

The volume serves both as a scholarly contribution and a practical guide for policymakers, planners, environmental NGOs, climate professionals, and graduate students concerned with the future of deltaic environments under climate change.
