In the coastal and humid tropical island region, waterlogging and soil salinity are serious threat to the sustainability of rainfed agriculture due to sea water inundation and intensive monsoon rainfall. In addition, there has been a marked change in surface temperature, rainfall, evaporation, and extreme events linked to climate change affecting the tropical islands. Therefore, an innovative management of waterlogged and saline soils of island ecosystem is imperative for sustainable agricultural production. The current technology enables the transfer of desirable genes from wild relatives to cultivated plants and improvement of land races followed by selection of crops and their varieties by the island farming community for waterlogged and saline conditions. The available evidences suggest that crop planning, multi-stress crop combinations, integrated farming system, and suitable agroforestry models have the potential to provide the basic needs of the people even under stressful and climate change situations. Land shaping measures have great potential to address waterlogging and salinity together while it promotes crop and farming system diversification which are more sustainable than monocropping with rice. In island conditions, rain water harvesting, storage, and its efficient use should be an integral part of the strategy for sustainable agricultural production. In addition, the livelihood of the people can be enhanced by suitable aquacultural practices in the coastal saline soils while sea weed cultivation holds greater promise to diversify the agricultural activities in the island saline environment.
