Tree growth serves as an important means to sequester atmospheric carbon dioxide in vegetation, soils and biomass. Estimation of vegetation and soil carbon stock of Populus deltoides plantation under social forestry scheme in Kurukshetra, Haryana in Northern India was carried out over a period of one year. The study revealed that the plantation had a significant carbon sequestration potential with vegetation carbon stock of 88.45 Mg/ha in different tree components with a carbon flux of 4.6 Mg/ha/yr. The net primary productivity of the plantation in terms of biomass accumulation was 9.74 Mg/ha/yr assimilating 16.97 Mg/ha/yr of carbon dioxide. The total STC stock of the plantation was 76.97 Mg/ha up to one meter depth of soil. Highest contribution (61-70%) to the percent weight of whole soil was from micro-...

Current projections of climate change constitute a further increase in average global surface temperature, increase in atmospheric carbon dioxide concentrations and changes in precipitation as well as altered disturbance regimes. A change of 1.8-4°C by 2090-2099 relative to that of 1980-1999 has been projected by IPCC AR4. Developing countries are going to bear the brunt of climate change and suffer most from its negative impacts. Mitigation measures in the forestry sectors are generating much interest as a potential means of adaptation to climate change and also as a source for additional income to rural population. Forest ecosystems are one of the most efficient systems in reducing greenhouse gas emissions, capturing carbon in soil and biomass, and reducing the vulnerability of people and ecosystems to t...

Studies were carried out to determine the physiological response of ten plant species. The leaf samples collected from these plant species were used to determine their plant APTI by calculating the ascorbic acid, total chlorophyll, pH, and relative water content for all selected sites. Highest pH, relative water content, ascorbic acid and total chlorophyll was observed in Castor (9.86), Parthenium (96.99%), Ficus benghalensis (14.90 mg g(-1)) and Amaranthus (7.08 mg g(-1)) at Yamuna river, Thermal power plant, Yamuna river and paper mill respectively. It was concluded that out of ten species studied only one species (Ficus benghalensis) showed moderately tolerant response in all selected sites, while other species showed sensitive response. According to observed APTI valu...
