Download or read book Historical Mapping and Monitoring of the Mangrove Forests of Ambergris Caye Belize Using Multi date Landsat Imagery written by Sandra Rhine and published by . This book was released on 2013 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ambergris Caye of Belize has in the last three decades become a hotspot for tourism and attracts snorkelers, divers, sight seers, beachcombers, and vacationers from all over the world. This growth in the tourism economy of Ambergris Caye has led to an increased pressure on the mangrove ecosystems due to the direct removal of mangrove habitat and replacing it with sewage ponds and infilling for roads, housing units and hotels. Decisions on environmental policies are hard to make and are compounded when there is a lack of knowledge on the amount and distribution of resources. Knowing how the quantity and quality of mangrove forests have changed through time will help facilitate decisions about how environmental policy needs to adapt to community concerns on the sustainability of their natural resource based tourism economy. In this study, I analyzed historical Landsat TM and ETM+ imagery of Ambergris Caye to examine how mangrove forest cover has changed from 1986 to 2012. Four classes were used based on spectral similarities: mangrove, water, non-mangrove vegetation, and residential/urban/barren land. Once mangrove areas were delineated a Normalized Difference Vegetation Index (NDVI) was performed to assess the health of the mangrove vegetation through time. Specifically, I mapped the historical spatial distribution and health of mangrove forests, examined the land use/land cover changes to mangrove forest distribution and health and assessed the rate of change throughout the study area over a 26 year period. Ambergris Caye lost 766 ha of mangrove forests through out the study time period. In total mangrove coverage went from 8535 ha in 1986 to 7769 ha in 2012 for a total decrease of 9%. Non-mangrove forest cover also decreased from 4408 to 3917 ha, an 11.1% decline. Mean while urban/barren growth increased 264% during the 26 year study. It is also important to note that Ambergris also lost 5% of its total land area to water. Mangrove quality on Ambergris decreased during the 26 year study period. In 1986, 3898 ha of mangrove forest was considered densely growing good quality mangrove habitat. By 1990 good quality mangrove forest coverage had decreased by 3% to 3777 ha. In 1995, mangrove quality dropped by 1% to 3731 ha. From 1995 to 2000 mangrove quality dropped by 9% with 3391 ha being considered good quality. From the year 2000 on mangrove quality dropped drastically going from 3391 ha to 2177 ha in the 2003/4 image. From 2003/4 to 2010/1 the good quality mangrove held relatively steady. However by 2012 only 1663 ha of quality mangrove habitat remains a 57% decrease in overall health from 1986 to 2012.

Furthermore, it discusses the use of hyperspectral remote sensing data for species level classification of mangroves, community zonation for biodiversity assessment and for preparing management plans for conservation. KEY FEATURES Exclusively covers the ecological state of Sundarbans (mangrove systems) through geo-informatic studies Describes the application of a combination of geomorphological, biogeochemical and remote sensing methods to the analysis of temporal changes Includes environmental factors affecting the health and decline of mangroves Covers biodiversity and ecological controls in mangroves ecosystems Discusses a remote sensing approach for tropical forested island and mangroves mapping This book is aimed at graduate students and researchers in environmental sciences, ecology, marine sciences, biology, geosciences and GIS/remote sensing areas.
Download or read book The Routledge Handbook of Indigenous Environmental Knowledge written by Thomas F. Thornton and published by Routledge. This book was released on 2020-11-29 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides an overview of key themes in Indigenous Environmental Knowledge (IEK) and anchors them with brief but well-grounded empirical case studies of relevance for each of these themes, drawn from bioculturally diverse areas around the world. It provides an incisive, cutting-edge overview of the conceptual and philosophical issues, while providing constructive examples of how IEK studies have been implemented to beneficial effect in ecological restoration, stewardship, and governance schemes. Collectively, the chapters in the Routledge Handbook of Indigenous Environmental Knowledge cover Indigenous Knowledge not only in a wide range of cultures and livelihood contexts, but also in a wide range of environments, including drylands, savannah grassland, tropical forests, mountain landscapes, temperate and boreal forests, Pacific and Indian Ocean islands, and coastal environments. The chapters discuss the complexities and nuances of Indigenous cosmologies and ethno-metaphysics and the treatment and incorporation of IEK in local, national, and international environmental policies. Taken together, the chapters in this volume make a strong case for the potential of Indigenous Knowledge in addressing today’s local and global environmental challenges, especially when approached from a perspective of appreciative inquiry, using cross-cultural methods and ethical, collaborative approaches which limit bias and inappropriate extraction of IEK. The book is a guide for graduate and advanced undergraduate teaching, and a key reference for academics in development studies, environmental studies, geography, anthropology, and beyond, as well as anyone with an interest in Indigenous Environmental Knowledge.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mangrove forests are critical to mitigating climate change and provide many essential benefits to their ecosystems and local environments but are under threat due to deforestation. However, monitoring mangroves through remote sensing can help pinpoint and alleviate the causes of their deforestation. Machine learning can be used with remotely sensed low-resolution satellite or high-resolution aerial imagery to automatically create mangrove extent maps with higher accuracy and frequency than previously possible. This study explores and offers recommendations for two practical scenarios. In the first practical scenario, where only low-resolution hyperspectral satellite imagery is acquired, we implemented several classical machine learning models and applied these results to data acquired in the Clarendon parish of Jamaica. We found that utilizing extensive feature engineering and hyperspectral bands can result in strong performance for mangrove extent classification, with an accuracy of 93% for our extremely randomized trees model. In the second practical scenario, we explored when there is full coverage of both low-resolution satellite and high-resolution aerial imagery over a survey area. We created a hybrid model which fuses low-resolution pixels and high-resolution imagery, achieving an accuracy of 97% when applied to a dataset based in Baja California Sur, Mexico, offering another high-performance method to automatically create mangrove extent maps if both high- and low-resolution imagery is available. Overall, the methods tested over these two scenarios provide stakeholders flexibility in data and methods used to achieve accurate, automatic mangrove extent measurement, enabling more frequent mangrove monitoring and further enabling the protection of these important ecosystems.

Book excerpt: Essay from the year 2006 in the subject Geography / Earth Science - Miscellaneous, grade: 1,7, University of Sheffield, language: English, abstract: The purpose of this work is to describe the application of remote sensing in the field of mangrove mapping. The question will be about the appropriate imagery and the diversity of processing methods. But first of all: What makes mangrove distinctive as a remote sensing target? Therefore, mangroves will be introduced with its ecological and physical properties. Furthermore, its significance for humans and the environment will be pointed out, which enforces the need to take care of this ecologically sensitive environment. This is why one should integrate the mangroves into coastal management processes. This requires knowledge about mangroves in their ecological habitats, from the micro-level, interrogated in the laboratory, up to a macro-level, observed from airborne or satellite platforms. Remote sensing will be introduced as an appropriate tool to map the extent and different habitats of mangroves and also to monitor dynamics over time.
