Abstract

Impact of Sethusamudram canal on the southeast coastal ecosystems is assumed to be diverse. The paper discusses the significance and status of the mangrove ecosystem in specific to Tamil Nadu coast, the impact of the project on the mangroves, the presumptive ecological and economical dynamics this also suggests a rational ecosystem management tool.

Abstract

Halophytes continue to be either under or unexplored in India. Many halophytic plants are of economicvalue and have industrial applications in the form of essential oils, medicinal, alcohol, fiber, latex, pulp,cosmetics etc. Salicornia spp extensively occur along Gujarat and Tamil Nadu coasts in the regularly(20-50 tides month-1) inundated inter tidal zones. Expanding saline wastelands, dubious rains,recurring droughts and soil erosion due to absence of green belt between sea and land ultimately leadto low productivity and poverty in these coastal regions.Seawater Agriculture is the strategy to link ecology and livelihood. Utilizing Salicornia to rehabilitatethe land and bio-prospecting biomedical compounds is a promising concept besides addressing theissues of desertification, salt intrusion and ultimately poverty alleviation. It is rational to implementpilot projects in different locations with commercial motives entangled with research conceptsstandardization.

Abstract

Continuous mangrove ecosystem degradation and coastal erosion is observed along the coastline of SungaiHaji Dorani, (N 03038’36.6”; E 101000’37.3” to N 03038’37.9”; E 101000’34.0”) Selangor, PeninsularMalaysia. Foreshore mangrove plantation challenges below mean sea level are in progress in this highenergy coast. There are interventions of gabion breakwaters and geo-textile tubes to alleviate the wavevelocity striking the shore. The area between the breakwaters and coastline is chosen for mangroveplantation. The soil is fluid silt sludge with average clay, silt and sand proportion of 43.03 %, 351.8 % and5.14 % respectively. The maximum height of the tide recorded onshore was 2.8 m and in the middle of theplantation area the height of the water flooding is ±3.5 daily during tides. Number of plant species on theSAUH concrete revetment is 43 with 12 mangrove species and on the fringe reference mangroves is 27 with8 true mangrove species. This paper explains the method to identify the potential location for mangroverehabilitation, possibility of establishing mangroves on the seafront in the chosen area and conservation ofthe existing strip with 14 mangrove species. Overall sediment accretion since May 2008 is ±0.0037cm perannum which is considerably negligible. Opening out the earthen bunds along the coastline is the actualsolution for natural mangrove translocation and stabilization in this particular coastline, however, it is notpractically possible. Hence, we have studied an alternative strategy of rehabilitating mangroves at theelevation of +0.5 m to 1m MSL along this shoreline and also in an engineered firm sediment filled zone. Wepropose carrying out hydrological restoration in the natural habitats for survival and further naturalcolonization of mangroves.
