Agroforestry has now emerged as an environmentally safe technology for the remediation of serious land degradation problems such as salt-affected soils, handling waterlogging particularly in canal command areas, and disposal of marginal waters. Not only the salt-affected soils in inland areas of arid and semiarid regions but also those in coastal areas can be made productive by adopting agroforestry techniques. The integrated farming systems involving multiple components such as tree plantations, fruit trees, agricultural crops, and animal and aquaculture components can be highly remunerative. Mangroves and associate vegetation play a crucial role in protecting shores and supporting wildlife and for the livelihood security of coastal people. Domestication of halophytes can be useful for food, fodder, oil, and medicinal and aromatic purposes. Salt-tolerant but high-productivity genotypes should be developed for greater viability. The latest information on these aspects has been compiled in a format that would be useful for scientists working on soil salinity, waterlogging, and poor-quality waters; policy makers; environmentalists; students; and educationists alike.
