Book Description
On December 26, 2004, the biggest earthquake in the past 40 years occurred under the sea near the west of Sumatra. Tsunamis never occurred before in the Indian Ocean, yet the earthquake created a powerful tsunami that killed more than 200,000 people and affected millions when it hit 11 countries around the Indian Ocean, including Thailand. While tsunami characteristics and effects are not fully understood, there are reports suggesting that mangroves, acting as a barrier, may be able to significantly reduce the devastation caused by the waves. In this study, we choose the worst-hit province in Thailand, Phang Nga, as our study area. The study focuses on the spatial association between mangrove forests and the damage. Using GIS and remote sensing techniques, we compile the data from various sources and detect the land cover changes to determine the level of damage in regions with and without mangroves. The proposed novel approach integrates GIS proximity analysis and change detection with remote sensing techniques to creatively delineated buffer zones from the coastline into four homogenous sub-regions. These techniques can provide an easy way to compare the patterns of damage in areas with different land characteristics and different distances from the coastline. The results show that the obvious damage of the tsunami is within the distance of 3 kilometers from the coastline. The areas near the coastline of all sub-regions show levels of damage with an average of 26.87%. In this study, we observe that mangroves can withstand the force of tsunami much better than regular vegetation and the areas behind mangrove forests also benefit from the protection. Our results could be useful for mangrove replantation and management in the future. Moreover, this study could be a prototype for studying impacts of the tsunami in other affected countries.

Book Description
The Asian "Mega Tsunami" (2004) has struck most of the territorial nations of South Asia including the East Coast of India. The NRDMS Division, Department  of Science and Technology, Government of India, New Delhi, has conceived and executed on All India Co-ordinated Programme on "Tsunami Disaster Assessment and Mitigation" through various institutions of expertise on Geomatics in Earth System Dynamics and the related natural disasters. The Geomatics technology which includes Arial Photography, Photogrammetry, Satellite Remote Sensing, Digital Image Processing, GPS Surveys, GIS modeling etc. was used in this programme, geo-spatial data bases were created on Tsunami disasters over Natural, Physical and Human Resources and futuristic mitigation strategies were evolved there from. The book illuminates the results of the studies carried out along the Indian Coast and a bird's eye view on the tsunami studies in Norway.   In addition, some special papers on the role of mangroves as Tsunami mitigator, Impacts o Tsunami over marine water quality, coral ecosystem etc; the administrator's experience over the tsunami crisis management, NGO's perspective, certain societal issues triggered by the killer Tsunami and citizen's perspective, etc. also find a place in this volume.

Book Description
Sundarbans, a UNESCO heritage site, is the world’s largest single chunk of mangroves distributed on the Indian and Bangladesh coasts. The mangroves and associated ecosystems are one of the most fertile ecosystems of the earth. Sundarbans Mangrove Systems: A Geo-Informatics Approach portrays different perspectives of studying Sundarbans and mangroves using geospatial analysis. This book highlights the major issues with the Sundarbans mangrove forest, its future conservation strategies and its ecological importance using geo-informatics technology. It explains the usage of remote sensing data for providing information about the present state of mangroves and their tropic status, including assessment in terms of extent, density of community, condition, diversity, identifying potential habitats and heterogeneity. 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.

Book Description
The intensive increase in land use change is considered both a source of richness and a serious problem to landscape sustainability. In this scenario, although land use change plays a very important role for societal development, the impact of land use changes on economic, social, and ecological functions requires special attention. The new environmental paradigms associated with globalization and progressive climate change will certainly intensify the entropy and the instability in most of the existing land-uses. In this regard, this book aims to highlight a body of knowledge related to the discussion of the opportunities and challenges associated with the development of new sustainable landscapes, considering current and future challenges related to land-use changes and planning.

Book Description
Mangroves are one of the most productive and biologically important blue-carbon ecosystems across the coastal intertidal zone of earth. In the current scenario of serious environmental changes like global warming, climate change, extreme natural disasters, mangrove forests play a vital role in mitigating greenhouse gas emissions and maintaining ecosystem balance. Mangroves are unique ecosystems with rich biological diversity of different taxonomic groups exhibiting great ecological and commercial importance. The book consolidates existing and emerging information on ecology of mangroves, with a special reference to their biodiversity and management. It emphasizes on the role of mangroves in providing various ecological services. The book is a comprehensive compilation covering all aspects of mangrove ecology. It is useful for students and researchers in ecology, plants sciences and environmental sciences.
