Mangroves, commonly found along sheltered coastlines in the tropics and subtropics, fulfil important socio-economic and environmental functions: providing wood and non-wood forest products, protecting shores against wind, waves and water currents; conserving biological diversity; protecting coral reefs, sea-grass beds and shipping lanes against siltation; and providing habitat, spawning grounds and nutrients for a variety of fish and shellfish, including many commercial species. High population pressure in coastal areas has, however, led to the conversion of many mangrove areas to other uses. The world's mangroves 1980-2005, prepared in the framework of the Global Forest Resources Assessment 2005, provides comprehensive information on the current and past extent of mangroves in all countries and territories in which they exist. This information, as well as the gaps in information that come to light in the report, will assist mangrove managers and policy- and decision-makers worldwide in ensuring the conservation, management and sustainable use of the world's remaining mangrove ecosystems
This Civil Engineering Book is one-of-a-kind. This book is structured to raise the level of expertise in Civil Engineering and to improve the competitiveness in the global markets. A civil engineer is someone who applies scientific knowledge to improve infrastructure and common utilities that meet basic human needs. Civil engineers plan, design and manage large construction projects. This could include bridges, buildings,dams, tunnels, buildings, airports, water and sewage systems, transport links and other major structures. They use computer modelling software and data from surveys, tests and maps to create project blueprints. These plans advise contractors on the best course of action and help minimise environmental impact and risk. Buildings and bridges are often the first structures to come to mind, because they are the most obvious engineering creations. But civil engineers are also responsible for less visible creations and contributions. Every time we open a water faucet, we expect water to come out, without thinking that civil engineers made it possible, in many cases by designing systems that transport water to cities from mountain sources that are sometimes hundreds of miles away. Civil engineering is one of the oldest and broadest engineering professions. It focuses on the infrastructure necessary to support a civilized society. The Roman aqueducts, the great European cathedrals, and the earliest metal bridges were built by highly skilled forerunners of the modern civil engineer. These craftsmen of old relied on their intuition, trade skills, and experience-based design rules, or heuristics, derived from years of trial and error experiments but rarely passed on to the next generation. This book of Civil Engineering covers Below Subjects ❏ FUNDAMENTALS ❏ BUILDING CONSTRUCTION ❏ CONCRETE TECHNOLOGY ❏ CONSTRUCTION ENGINEERING ❏ ENVIRONMENTAL SCIENCE AND ENGINEERING ❏ GEOTECHNICAL ENGINEERING ❏ GEOTHERMAL ENGINEERING ❏ HYDRAULICS ❏ PAVEMENT ❏ STRUCTURAL ENGINEERING ❏ TRANSPORTATION ENGINEERING ❏ MUNICIPAL SOLID WASTE MANAGEMENT ❏WATER RESOURCES ENGINEERING In contrast, today's civil engineers bring to bear on these problems a knowledge of the physical and natural sciences, mathematics, computational methods, economics, and project management. Civil engineers design and construct buildings, transportation systems (such as roads, tunnels, bridges, railroads, and airports), and facilities to manage and maintain the quality of water resources. Society relies on civil engineers to maintain and advance human health, safety, and our standard of living. Those projects that are vital to a community's survival are often publicly funded to ensure that they get done, even where there is no clear or immediate profit motive.
This book outlines the performance and management of mangroves in the changing climatic scenario of the Asia-Pacific region and draws examples and lessons from the national and community-driven mangrove conservation programs of relevant countries including Pakistan, India, Bangladesh, Sri Lanka, Myanmar, Thailand, Cambodia, Indonesia, the Philippines, and Japan as well as the Pacific islands. By highlighting the major drawbacks that hinder effective mangrove conservation, the book contributes towards enhancing climate resilience of communities through proposition of corrective methods and ameliorative approaches of mangrove conservation. Mangroves play an important role in adapting to climate change and provide a plethora of ecosystem services that are fundamental to human survival. Yet these ecosystems are exceptionally prone to extinction due to increased human interventions and changes in environmental boundary conditions. Especially in the Asia-Pacific region, mangroves have dwindled at an exceptional high rate over the past three decades. As the threat of climate change hovers over millions of people in this region, particularly those who crowd the low-lying coastal areas, conservation/restoration of mangroves through appropriate policies and practices remain highly imperative. The primary target readers for this book are students and researchers in the fields of conservation and management of mangroves, especially from the developing tropical countries of the Asia-Pacific region. Other target groups comprise policy planners, practitioners, and NGO workers, who will be able to apply the collective knowledge from this work towards proactive mangrove conservation through effective mediation in local communities.
During the past 10 years following the 2004 Indian Ocean Tsunami, invaluable lessons have been learned and great changes have been observed. Immediately after the disaster, the second World Conference on Disaster Reduction was held in Kobe, Japan, and formulated the Hyogo Framework for Action (HFA: 2005–2015). HFA provided a platform and framework for changes and innovations, many of which were part of the recovery programs in the different countries affected by the 2004 disaster. This book is a modest attempt to review the lessons learned through the recovery process in the affected region. The book has 31 chapters, drawing lessons from four countries: India, Indonesia, Sri Lanka, and Thailand. There are five sections: Overview (10 chapters), Indonesia (8 chapters), India (6 chapters), Sri Lanka (5 chapters), and Thailand (2 chapters). The primary target groups for this book are students and researchers in the fields of disaster risk reduction, environment, and development. The book provides them with a good idea of the current research trends and lessons over the past decade of recovery initiatives. Another target group comprises practitioners and policy makers, who will be able to apply the knowledge collected here to establishing policy and making decisions.
During the last decades, soil organic carbon (SOC) attracted the attention of a much wider array of specialists beyond agriculture and soil science, as it was proven to be one of the most crucial components of the earth’s climate system, which has a great potential to be managed by humans. Soils as a carbon pool are one of the key factors in several Sustainable Development Goals, in particular Goal 15, “Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification and halt and reverse land degradation and halt biodiversity loss” with the SOC stock being explicitly cited in Indicator 15.3.1. This technical manual is the first attempt to gather, in a standardized format, the existing data on the impacts of the main soil management practices on SOC content in a wide array of environments, including the advantages, drawbacks, and constraints. This manual presents different sustainable soil management (SSM) practices at different scales and in different contexts, supported by case studies that have been shown with quantitative data to have a positive effect on SOC stocks and successful experiences of SOC sequestration in practical field applications. Volume 2 includes a description of hot spots of SOC stocks. This manual defines hot spots of SOC as areas that represent a proportionally little of the global land surface but on which SOC storage is highly effective; bright spots as large land areas with low SOC stocks per km2 that represent a potential for further carbon sequestration.
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.

Despite the central role oceans play in the economic, environmental and social affairs of the planet's 6.7 billion inhabitants, significant gaps exist in our understanding and management of the complex processes at work from the global climate system, to the water cycle and circulation of nutrients, to changes affecting marine habitats. In addition, the vastness of the world's oceans have for far too long been perceived as impervious and indestructible to human impact. To deal with this situation, improved monitoring and observation practices, regular assessments to provide a deeper understanding of the status and trends of environmental changes, and the know-how and ability to prevent, mitigate and adapt to these changes are urgently required. The UN General Assembly in 2005 -- recommended that a regular process for the global reporting and assessment of the state of the marine environment, including its socio-economic aspects (Regular Process), be initiated. The UN Environment Programme (UNEP) and the Intergovernmental Oceanographic Commission of UNESCO (IOC-UNESCO) were asked to serve as the lead agencies in the start-up phase that came to be known as the "Assessment of Assessments" (AoA). Under the AoA, an Expert Group have developed options and a framework for such a Regular Process, which can serve as the mechanism to keep the world's oceans and seas under continuing review.
