Coastal Ecosystems of the Tropics - Adaptive Management

Description

The coastal areas of the tropics are rich in biodiversity, natural resources and place of intensive developmental activities as it provides livelihood to millions of people. At the same time evidences suggest that several unique coastal ecosystems viz., mangroves, wetlands, salt marshes, corals, estuaries, sand dunes and agro-ecosystem are vulnerable to natural disasters and events associated with global climate change. In recent times degradation of land, water and genetic erosion besides threat to native flora and fauna have been increasing due to unsustainable developmental activities. Therefore, a paradigm shift in deriving livelihood through conventional methods, developmental strategies, conservation practices are required for balanced and sustainable growth of the coastal areas. This publication strives to cover the status of different natural resources of the coastal region, various aspects of degradation process, production need and restorative methods besides new technological options and its socio-economic implications with case examples. Special focus is given to bring out the scope and potential of mangrove based farming, integrated and organic farming and its value addition besides the role of coastal vegetations as bioshield in protecting these regions from sea erosion, cyclones and tsunami. As the tropical coastal areas are vulnerable to climate change events, this book also covers the recent weather pattern, impacts of climate change and climate resilient technologies besides intuitional linkages and policy framework aimed at balancing development and environmental concerns.
