Environmental Remote Sensing In Egypt

This book presents a comprehensive selection of applications employed in environmental remote sensing using optical and thermal infrared satellite-sensors aiming to map natural resources, crops, groundwater, surface water, aquatic ecosystem, land degradation, air quality, renewable energy, regional resources, and climate-related geophysical processes. The technologies presented in this book also include satellite images, space-borne radar sensors focusing on the most versatile one, data from synthetic aperture radar (SAR), scatterometers and radar altimeters in Egypt. This volume also presents a thorough explanation of the remote sensing role showing physical fundamentals of the climate change phenomenon including gas emissions, and the impact on resources concerning the sustainable development of Egypt. Besides, the book includes an analysis of oil pollution in both Mediterranean and Red Seas This book is intended for environmental policymakers working in Egypt as well as scientists working with remote sensing technologies in highly populated arid regions.

This book covers various aspects of remote sensing and geographic information systems, from the perspective of earth and environmental sciences. The theme of applications of remote sensing and geographic information systems for the purposes of sustainable development highlights the innovative usage of space imaged spectral data in soil characterization. This book merges the selected contributions to the First International Conference of Remote Sensing and Space Sciences Applications (Egypt 2022) aiming to promote the latest findings on the development of Space Technologies and Applications.

This book focuses on monitoring and assessing various environmental processes in Tunisia using state-of-the-art remote sensing and GIS technologies. In addition to addressing the diversity of Tunisian landscapes and providing spatial analysis of natural, cultivated and urbanized environments. It presents and discusses several case studies on integrated RS / GIS approaches for mapping, modeling, monitoring and evaluation. Moreover, in this volume authored by experts in the topic from Tunisia and other countries, authors assess the agro-environmental applications from Tunisia and offer different methods and applications to environmental processes and risks including drought, degradation, flood, planning, Yield estimation, dust storm detection, dry land vulnerability, wetland dynamics and others. The material presented here will help decision-makers plan sustainable landscape and agricultural management policies that preserve biodiversity and contribute to achieving sustainability goals and for researchers, it will expose methodological approaches used in different fields of research. Graduate students and Practionioner engineers working in the field of RS/GIS will also benefit from the book. The book ends with a set of conclusions and recommendations to support researchers underscoring the need for further research in this area.

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.

In recent decades, remote sensing technology has been incorporated in numerous mineral exploration projects in metallogenic provinces around the world. Multispectral and hyperspectral sensors play a significant role in affording unique data for mineral exploration and environmental hazard monitoring. This book covers the advances of remote sensing data processing algorithms in mineral exploration, and the technology can be used in monitoring and decision-making in relation to environmental mining hazard. This book presents state-of-the-art approaches on recent remote sensing and GIS-based mineral prospectivity modeling, offering excellent information to professional earth scientists, researchers, mineral exploration communities and mining companies.

The African Seas include marginal basins of two major oceans, the Atlantic and the Indian, a miniature ocean, the Mediterranean Sea, and an infant ocean, the Red Sea. Understanding the wide spectrum of environmental features and processes of such a varied collection of marine and coastal regions requires that in situ observation systems be integrated and actually guided, by the application of orbital remote sensing techniques. This volume reviews the current potential of Earth Observations to help in the exploration of the marginal seas around Africa, by virtue of both passive and active techniques, working in several spectral ranges – i.e. measuring either reflected visible and near-infrared sunlight, as well as surface emissions in the thermal infrared and microwave spectral regions, or again the surface reflection of transmitted lidar or radar impulses of visible or microwave radiation. The in-depth evaluation of the advantages offered by each technique and spectral region and in particular by the development of advanced multi-technique systems, contributes to the assessment of the abundant natural resources that the Seas of Africa have to offer, of those in dear need of being – sustainably – exploited and of others that should be protected and maintained in their still pristine conditions.
