Book excerpt: The marshes of Mesopotamia at the southern part of Iraq, the largest wetland in the middel east, represent a unique component of our global heritage. The area of marshes fluctuated between 15,000 to 20,000 square kilometers. The marshes cut across three Iraqi southern provinces: Misan, Dhi-Qar and Al-Basrah. The heartland of the marshes comprised three principal areas Al-Hammar, The Central and Al-Hawaizah marshes. During the last decades the Iraqi marshes subjected to many changes, these changes have great impact on marshes environmental and ecosystem. The goal of this book was to detect the environmental changes in Iraqi marshes that represented main land cover in the area for the period 1973-2004, using multi-temporal and multi-spectral satellite images. Landsat images have been used as a tool for detecting and studying land cover changes and its impact on the environment of Iraqi Marsh area

This book was released on 2019-08-29 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book focuses on remote sensing (RS) and geographical information systems (GIS) in Iraq. The environmental applications include monitoring and mapping soil salinity and prediction of soil properties, monitoring and mapping of land threats, proximal sensing for soil monitoring and soil fertility, spatiotemporal land use/cover, agricultural drought monitoring, hydrological applications including spatial rainfall distribution, surface runoff and drought control, geo-morphometric analysis and flood simulation, hydrologic and hydraulic modelling and the effective management of water resources. Also, this book assesses the impacts of climate change on natural resources using both RS and GIS, as well as other applications, covering different parts of Iraq. The book chapters include tens of maps extracted from the remotely sensed datasets, in addition to tables and statistical relations obtained from the results of the studies of the chapters' authors. These studies have been conducted in different parts of Iraq; in the north (Kurdistan region) with its mountainous and undulating lands, in western parts which have desert soils, and in central and southern Iraq where there are salty soils, dunes, wetlands, and marshes. The book is written by distinguished scientists from Iraq, China, USA, Italy, Iran, Germany, and the Czech Republic who are interested in the Iraqi environment. The book is therefore a useful source of information and knowledge on Iraqi environment for graduate students, researchers, policy planners, and stakeholders in Iraq as well as similar regions.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Study of salt marsh biophysical properties is imperative to understand its response to environmental change. We developed protocols for mapping biophysical properties of salt marshes such as Green Leaf Area Index (GLAI), Canopy Chlorophyll (CHLc), Vegetation Fraction (VF), and aboveground Green Biomass (GBM) using moderate resolution satellite images and in-situ data for the salt marshes in south-eastern United States. The time-series products derived using the biophysical models have been able to capture the spatio-temporal effects of the environmental events affecting the salt marshes of the region. We also tested the performance of different smoothing functions to derive noise-free phenology for Louisiana (LA) and Georgia (GA) salt marshes from the time-series GBM composites, and selected the best smoothing function to derive and analyze phenological parameters for salt marsh habitats. Long-term trend analysis of phenological parameters indicate positive changes in the base GBM values, and mostly negative changes in the GBM amplitude and small seasonal integral, which indicate overall progressive decline in the rates of photosynthesis and biomass allocation in the salt marsh ecosystem. This observed decline in photosynthesis and biomass allocation may be attributed to elevated atmospheric carbon dioxide (CO2) levels and sea level rise. Finally we attempted to map Gross Primary Productivity (GPP) for a salt marsh habitat in the Gulf Coast, using the GBM composites and in-situ GPP estimates from eddy covariance CO2 flux towers. The time-series composites and phenological charts developed using the biophysical GPP model was able to capture the effect of different environmental events such as dieback and hurricane landfall. The results illustrate the relative efficiency of MODIS in analyzing salt marsh biophysical properties. This is the first study to employ MODIS images to study the long-term trends in biophysical characteristics of salt marshes in south-east United States. The methods described in this study as well as the biophysical products derived using the methods has the potential to improve our ability to predict their productivity and carbon sequestration potential. These techniques could also be used to assess the success of previous and ongoing salt marsh restoration projects, and evaluate the productivity of marshes under threat from both natural and anthropogenic drivers.

Download or read book Improving Projections of Tidal Marsh Persistence Under Climate Change with Remote Sensing and Site Specific Data written by Kevin John Buffington and published by . This book was released on 2017 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tidal marshes are dynamic ecosystems that are threatened by climate change and sea-level rise. To characterize baseline condition and historic climate sensitivities, and improve projections into the future, new methods are required that integrate data from the field and remote sensing platforms. Marsh elevation response models can be calibrated with site-specific data to determine the vulnerability of a marsh to sea-level rise and help guide management decisions. Elevation models are sensitive to initial elevation, the rate of accretion, and aboveground biomass. The overarching goal of this dissertation was to develop techniques to improve these important model inputs and evaluate the range of spatial and temporal variation. Light detection and ranging (lidar) is an invaluable tool for collecting elevation data, however dense vegetation prevents the accurate measurement of the tidal marsh surface. In Chapter 2, I describe the development of a technique to calibrate lidar digital elevation models with survey elevation data using readily available multispectral aerial imagery from the National Agricultural Inventory Program (NAIP). Using survey elevation data across 17 Pacific Coast tidal marshes, I demonstrated the utility of the Lidar Elevation Adjustment with NDVI (LEAN) technique to account for the positive bias in lidar due to vegetation. LEAN reduced error from an average of 23.1 cm to 7.2 cm root mean squared error and removed the positive bias caused by vegetation. This increase in accuracy will facilitate more accurate assessments of current and future vulnerability to sea-level rise. The phenology of aboveground biomass in tidal marsh plants in relation to climate variation has not been explored in the Pacific Northwest (PNW). In Chapter 3 I explain how I leveraged the Landsat archive and cloud computing capabilities to assess how Tasseled Cap Greenness (TCG, a proxy for aboveground biomass) in three PNW tidal marshes has responded to recent variation in climate to characterize sensitivity to climate change. Through analysis of over 3700 Landsat images obtained from 1984-2015, I found increased annual precipitation resulted in a higher peak TCG, while warmer May temperatures resulted in an earlier day of peak TCG. These results also demonstrate how time-series analysis of remote sensing data can be used to examine the sensitivity of tidal marsh plants to climate variability and directional change. The range of variation in tidal marsh accretion rates has not been characterized across the PNW. For Chapter 4, I collected and analyzed twenty-two soil cores from eight estuaries to estimate historic accretion rates with radioisotope dating techniques and evaluated the amount and source of variation across estuaries. I found that tidal marshes across the PNW had accretion rates greater than the current rate of sea-level rise, ranging from 2.3 – 7.3 mm yr−1. Using a watershed-scale analysis, I found that long-term average annual fluvial discharge was the top predictor of tidal marsh accretion rates. Additionally, I found that calibrating the Wetland Accretion Rate Model for Ecosystem Resilience (WARMER) with accretion rate data from nearby estuaries can result in uncertainties of up to 41% (50 cm) after 100 years. Finally, in Chapter 5, I demonstrate that a range of 62 cm of error is possible in WARMER models after a 100 year simulation when both uncorrected lidar and non-local accretion rates are used, fundamentally changing the interpretation of the results. Altogether, this dissertation illustrates the importance of collecting site-specific wetland vegetation and elevation data and demonstrates how lidar and multispectral remote sensing data can be leveraged to improve our understanding of how climate variability and change impacts coastal ecosystems.
