Tropical deltas and coastal zones : food production, communities, and environment at the land-water interface

Tropical coastal deltas represent one of the most diverse and rapidly changing biophysical regions in the developing world. These deltas are home to large populated areas, are significant centres of agricultural production and industrial development, and contain fragile ecosystems that are now facing new threats as a result of expected sea-level rises associated with global warming. Focusing on the developing countries of Asia, Africa and South America, chapters explore the diverse livelihoods of people in these areas and the impact of land-water management on the environment. New techniques and methodologies are explored in land and water management to try and solve the conflicts between rice-based agriculture, aquaculture, fisheries and the environment in tropical delta regions. Illustrating how to protect tropical deltaic systems in the face of serious future challenges, this will be essential reading for students, researchers, policy makers and natural resource managers in agriculture and aquaculture.

existing land and water management practices on delta environments. New management techniques are also explored, which address conflicts between rice-based agriculture, aquaculture, fisheries, and the emerging threat of climate change. Illustrating the current key management challenges involved in protecting tropical deltaic systems in the face of environmental change, this book will be an essential reference for students, researchers and policy makers in agriculture, environmental science and aquaculture. --Book Jacket Coastal deltas represent one of the most diverse biophysical regions in the tropical developing world. These regions are also home to large human populations and are significant areas of agricultural production and industrialization. Tropical deltas currently face a number of environmental pressures stemming from their intensive use and rapid development, and new threts are emerging as a result of global climate change and expected sea-level rise Tropical coastal deltas represent one of the most diverse biophysical regions in the developing world. Focusing on the developing countries of Asia, Africa and South America, this title explores the diverse livelihoods of people in these areas and the impact of land-water management on the environment
