  • Seasonal variations of net ecosystem (CO2) exchange in the Indian tropical mangrove forest of Pichavaram

    Mangrove ecosystems play a crucial role in the global carbon cycle. However, the carbon fluxes in the mangrove ecosystems found in the Indian subcontinent are not well understood. Here, for the first time, we estimate the net ecosystem exchange (NEE) in a mangrove ecosystem at Pichavaram, southeast India, using the eddy covariance method for the period October 2017–September 2018. The half-hourly daytime NEE varied from-11.05 μmol m2 s1 in the winter months (January–March 2018) to-6.06 μmol m2...

  • Gulf of Mannar Marine Biosphere Reserve Strategies for Conservation and Management

    Under the Wild Life Protection Act (1972) and several state laws and statutes may Wildlife Areas have been declared by State Governments as National Parks and Sanctuaries. About 3.7% of the Reserved Forest area is thus under the protected areas system now. Of late there is a distressing and disturbing trend in the management of the protected areas due to factors such as conflicts with local communities commercial activities, poaching and inadequate understanding of the importance of protected...

  • A Gendered Analysis of Fisherfolk’s Livelihood Adaptation and Coping Responses in the Face of a Seasonal Fishing Ban in Tamil Nadu & Puducherry, India

    This study investigates how people respond to economic stresses incurred as a result of natural resource regulations. Previous research has demonstrated that in some cases, men and women adapt differently to livelihood stresses. We argue that looking only at an individual’s sex is insufficient for understanding why they adapt the way they do. Instead, using the framework of intersectionality, we examine individuals’ adaptation strategies and coping responses influenced not only by their sex but...

  • Gaja cyclone: Revival of livelihood and restoration of greenery in the coastal areas of Nagapattinam District

    According to the Indian Meteorological Department, Government of India, a severe cyclonic storm named ‘Gaja’ crossed the Tamil Nadu coast between Nagapattinam and Vedaranniyam near latitude 10.5ºN and longitude 79.8ºE with a wind speed of 100‒110 km/h gusting to 120 km/h during 0030 to 0230 hours on 16th November, 2018 (Fig 1). It was reported by private weather observers that in Vedaranyam the speed of the cyclonic wind was more than 160 km/h. As per the observation of fishers, the cyclonic...

  • Pichavaram mangrove Wetland: Situation Analysis

    Tamil Nadu has a coastline of 950 km. Extensive mangrove wetlands are located in two places – in Pichavaram, Cuddalore districts and Muthupet in Thiruvarur and Thanjavur districts. Small patches of mangroves have also been found along the Palk Strait as well as in some of the islands of the Gulf of Mannar Biosphere Reserve. All these mangrove wetlands have been declared as Reserve Forests (absolute property of the government) and are managed by the Tamil Nadu Forest Department.

  • Climate Change induced sea-level rise projections for the Pichavaram mangrove region of the Tamil Nadu coast, India:

    Climate change induced sea-level rise poses serious threats to valuable coastal ecosystems like mangroves. However, projections of sea level rise at local level under different scenarios and for different time scale set forth greatest challenges to climate modelers. Further, information on location specific sea-level rise projections at local level are seldom available and rarely in the possession for the coastal managers and adaptation planners to frame suitable adaptation strategies to sea-...
