The dynamics in the distribution of mangrove forests in Pichavaram, South India – perception by user community and remote sensing

Changing perspectives of mangrove management in India – An analytical overview

“…Mangroves provided valued ecological and environmental services in the past, especially; the preventive role of mangroves in storm protection and disaster risk reduction has been proved vital in time of critical disasters such as Orissa cyclone (1999) & Indian Ocean Tsunami (2004) (Badola and Hussain, 2005;Kathiresan and Rajendran, 2005;Das, 2012). Notably, an increased community perception about the protective role in time of intense disaster significantly contributed to mangrove conservation (Badola and Hussain, 2005;Gnanappazham and Selvam, 2011). Therefore, ecosystem stress reduction and rejuvenation of the ecosystem services of mangroves are considered as an important component of mangrove management.…”

“…Earliest available estimation reveals that despite of considerable loss over the precedent decades, mangrove habitats in India covered close to 6000 sq. km even during 1960s (FAO, 2003;Gnanappazham and Selvam, 2011). Since then, Indian mangroves suffered significant loss leading to a gross mangrove area of 4046 sq km in 1987.…”

Osmotolerant Microbial Resources of Saline Ecologies of India: Dynamics and Potential

“…km (6800 ha) area and 11 km 2 lagoon on the East coast of India and form a part of the Great Vedaranyam swamp (Table 11.2, Fig. 11.1) (Ashokkumar et al 2011;Lakshmanan and Selvam 2011;Govindasamy et al 2012;Srivastava et al 2012). The soil contains total N 3.70-8.96 μg/g, P 0.947-2.827 μg/g and OC 3.721-6.576 mg/g (Ashokkumar et al 2011).…”

Developing a spectral library of mangrove species of Indian east coast using field spectroscopy

“…Several studies including remote sensing aided vegetation community mapping had been carried out throughout the world and the same were reviewed in detail by Kuenzer et al (2011). Plant community level mapping was carried out for the entire mangroves of India using data from LISS III (Linear Imaging Self Scanning Sensor) of IRS 1C (Indian Remote Sensing) and IRS 1D satellites (Nayak 4 and Bahuguna 2001;Ajai et al 2012) and study about its dynamics in the distribution was also well discussed (Gnanappazham and Selvam 2011). However, the extensive literature review reveals that studies related to species level discrimination of mangroves are very limited in India mainly due to the limitations in deriving spectral information from multispectral satellite data.…”
