Recent Advances in Environmental Science from the Euro-Mediterranean and Surrounding Regions (3rd Edition)
This edited book includes over one hundred and eighty short papers that were presented during the third edition of EMCEI, which was held in Sousse, Tunisia, in June 2021. Nowadays, experts as well as most of the general public know that the Mediterranean and surrounding regions are facing environmental degradation that is accelerating at an unprecedented rate. The main causes are the natural and human induced climate change, increasing pollution, urban growth, and the overexploitation and unsustainable use of resources due to rapid population growth. The effects are seen in several indicators such as the warming, more frequent extreme events, severe droughts, water shortages, contraction of natural resources, changes in land use and landscape deterioration, decreasing agricultural yields, biodiversity loss, deterioration of the ecosystems, corrosion of the natural coastal environment, sea-level rise, and ocean acidification. In addition to these more recent issues, the Mediterranean and surrounding region naturally experience a number of hazards such as floods, droughts, desertification, fires, catastrophic forest diebacks, earthquakes, and volcanic eruptions. By presenting a wide range of environmental topics and new findings relevant to a variety of problems in these regions, this book appeals to anyone working in the subject area and especially students interested in learning more about new developments in environmental research initiatives in light of the worsening environmental degradation of the Mediterranean and surrounding areas, making environmental and resource protection an increasingly important issue that impedes sustainable development and social well-being. The book addresses emerging environmental issues along with new challenges by focusing on innovative approaches that contribute to achieving a sustainable environment in and around the Mediterranean Sea and by highlighting to decision makers from relevant sectors the environmental considerations that should be integrated into their own activities.
A Multi-Layer Based Assessment of Wetland Changes in the Southern Iraqi Marshlands Using Remotely Sensed Data
Marshlands are important ecosystem for living organisms. The Southern Iraqi Marshland is the central habitat for freshwater fish, provides habitat for important populations of wildlife and serves as a source of income for native economies through reed harvesting. Studies have shown that variability in climate and human-induced factors affects the spatial dynamics of marsh ecosystems. This study assessed wetland changes in the Southern Iraqi Marshlands using Remotely Sensed Data from 1986 to 2019 using Landsat satellite imagery for four epochs: 1986, 2000, 2010 and 2019. To achieve this, thirty (30) pixels were obtained in selected land cover theme and their signatures were merged into one class. Furthermore, the selected pixels were re-coded and merged into ten (10) land cover classes. The multi-layer classes created were shallow water, deep water, dense marsh, medium marsh, sparse marsh, dense vegetation, medium vegetation, sparse vegetation, dry soil and wet soil. The areal extents of the land cover types were calculated for 1986, 2000, 2010 and 2019. Normalized Difference Vegetation Index (NDVI) differencing was also carried in order to highlight trends in vegetation from 1986 to 2019. The study correlated historical trends of human activities as a central factor in the degradation of marshland (by 16.25%) from 1986 to 2000. However, by the year 2000 to 2010, there was an 11.36% increase in the total marshland area, which remained almost unchanged between 2010 and 2019. In 1986, NDVI was relatively stable at 0.73 in the Al-Hammar and Al-Hwaizeh Marsh. However, by 2000, the areas of dense vegetation cover reduced drastically by over 90%. In 2010, the NDVI index indicated trends of increasing water body and an outward cluster of healthier vegetation continuing to 2019.
Southern Iraq's Marshes
The Mesopotamian marshes are important for economic, social, and biodiversity values and have been home to indigenous human communities for millennia. They are regarded as a legendary site. This multi-authored book contains chapters written by world-renowned experts in their field. Both basic and applied information are made available, making the book a must-have for a wide spectrum of users. For example, an understanding of the natural and the social aspects of the marshes, as described here, is an obvious prerequisite for a pest management plan in this area. Scholars interested in wetlands can use this book as a guide to compare different wetlands areas in Asia. The bibliography section contains valuable references to the marsh areas and research in the field. This book serves as an up-to-date comprehensive source of information on different aspects of the southern marshes of Iraq and is aimed at academic scholars, environmentalists, and decision makers.
