The coastal agro-ecosystem provides protective, productive and economic benefits to the coastal communities. Sustainability of coastal agro-ecosystem is dependent on its food production system, water quality and biodiversity. The natural resources such as carbon and other elements that are stored in ecosystems are now being extracted and exploited, and the land becomes depleted from its original vegetation and abandoned as degraded lands. The soils are generally saline, poor in nutrients and low in water holding capacity. The status and extent of degraded lands in the coastal agro ecosystem of Northern Tamil Nadu were assessed and confirmed using surface soil analytical results. Based on the soil texture, drainage class and LGP, the villages of Northern coastal agro ecosystem of Tamil Nadu was divided in to seven agro ecological sub zones viz., Northern Cauvery delta, Ponaiyar delta, Pondicherry region, South Palar delta, North Palar delta, Mahabalipuram region and North Chennai. The soil profile samples were also subjected to various analyses to characterize the physico-chemical properties of each degraded site.
