Salinity based allometric equations for biomass estimation of Sundarban mangroves.

Abstract: Biomass estimation was carried out for three even-aged dominant mangrove species ( Avicennia alba , Excoecaria agallocha and Sonneratia apetala ) in two regions of Indian Sundarbans with two distinct salinity regimes for three consecutive years (2008–2010) and the results were expressed in tons per hectare (t ha −1 ). In the western region, the total mean biomass of the mangrove species varied as per the order A. alba (41.65 t ha −1 in 2008, 55.79 t ha −1 in 2009, 60.86 t ha −1 in 2010) > S. apetala (31.76 t ha −1 in 2008, 32.81 t ha −1 in 2009, 39.10 t ha −1 in 2010) > E. agallocha (13.89 t ha −1 in 2008, 15.54 t ha −1 in 2009, 18.28 t ha −1 in 2010). In the central region, the order was A. alba (42.06 t ha −1 in 2008, 57.09 t ha −1 in 2009, 64.57 t ha −1 in 2010) > E. agallocha (15.30 t ha −1 in 2008, 20.02 t ha −1 in 2009, 24.24 t ha −1 in 2010) > S. apetala (6.77 t ha −1 in 2008, 9.46 t ha −1 in 2009, 11.42 t ha −1 in 2010). Significant negative correlation was observed between biomass of S. apetala and salinity ( p A. alba and E. agallocha positive correlations were observed ( p R 2 value). The allometric models are species-specific, but not site-specific.

Potential of Neglected and Underutilized Yams (Dioscorea spp.) for Improving Nutritional Security and Health Benefits.

Abstract: Food and nutritional security are the major concerns in many countries of the world and may have potential to contribute to sustainable food systems under climate change. To address the food and nutritional insecurity, it has become extremely important to diversify the present-day agricultural system as well as to search for alternative food and feed ingredients. Some wild root and tuber crops occupy a remarkable position toward food security of the developing world due to their high calorific value and superior carbohydrate content. Yam (Dioscorea spp.) provides food and medicines to millions of people in the world especially in the tropics and sub tropics. It is recognized as the fourth most important tuber crop after potatoes, cassava, and sweet potatoes. It contributes about 10% of the total root and tubers production around the world. Yams also considered as famine food and plays a prime role in the food habit of small and marginal rural families and forest-dwelling communities during the food scarcity periods. These species are unique for their food, medicinal and economic values but their wider utilization is limited due to the presence of anti-nutritional compositions. This paper describes the ethnobotany of yam species in relation to their nutritional, anti-nutritional and pharmacological properties and highlights the potentiality for food and nutritional security for combating the "hidden hunger" caused by micronutrient deficiencies.

Climate change-induced salinity variation impacts on a stenoecious mangrove species in the Indian Sundarbans.

Abstract: The alterations in the salinity profile are an indirect, but potentially sensitive, indicator for detecting changes in precipitation, evaporation, river run-off, glacier retreat, and ice melt. These changes have a high impact on the growth of coastal plant species, such as mangroves. Here, we present estimates of the variability of salinity and the biomass of a stenoecious mangrove species (Heritiera fomes, commonly referred to as Sundari) in the aquatic subsystem of the lower Gangetic delta based on a dataset from 2004 to 2015. We highlight the impact of salinity alteration on the change in aboveground biomass of this endangered species that, due to different salinity profile in the western and central sectors of the lower Gangetic plain, shows an increase only in the former sector, where the salinity is dropping and low growth in the latter, where the salinity is increasing.
