Abstract

Tropical coastal lands are vulnerable to different processes of land degradation such as salinization, waterlogging, drainage congestion, erosion, and acid sulphate formation. This is a serious impediment for agricultural growth and sustainable utilization of natural resources in the coastal region. Rehabilitation of degraded land is vital for improving the coastal ecosystems and provisioning of ecosystem services to support livelihood of coastal communities. Implementing innovative land management measures such as permanent raised beds and furrow; rice-cum-fish; three-tier land management; ponds with broader dykes, deep furrow, and high ridge; ridges and furrow systems; and brackish water aquaculture in combination with productive utilization of socio-economic opportunities of the coastal areas will help to address the land degradation concerns. Besides, these methods also enable to harvest rainwater and diversification of agriculture by favouring integration of fish and livestock components with crop cultivation providing greater stability to farm income. These land shaping methods also help to cope with the weather variations and projected impact of climate change.
