Management of temperate forests has the potential to increase carbon sinks and mitigate climate change. However, those opportunities may be confounded by negative climate change impacts. We therefore need a better understanding of climate change alterations to temperate forest carbon dynamics before developing mitigation strategies. The purpose of this project was to investigate the interactions of species composition, fire, management and climate change on the Copper–Pine creek valley, a temperate coniferous forest with a wide range of growing conditions.

Biochar, a carbon-rich, porous pyrolysis product of organic residues may positively affect plant yield and can, owing to its inherent stability, promote soil carbon sequestration when amended to agricultural soils. Another possible effect of biochar is the reduction in emissions of nitrous oxide (N2O). A number of laboratory incubations have shown significantly reduced N2O emissions from soil when mixed with biochar.

Palustrine wetlands(PWs) include all bogs, fens, swamps and marshes that are non-saline and which are not lakes or rivers. They therefore form a highly important group of wetlands which hold large carbon stocks. If these wetlands are not protected properly they could become a net carbon source in the future. Compilation of spatially explicit wetland databases, national inventory data and in situ measurement of soil organic carbon (SOC) could be useful to better quantify SOC and formulate long-term strategies for mitigating global climate change.

Exports of pellets from the United States(US) are growing significantly to meet the demand for renewable energy in the European Union. This transatlantic trade in pellets has raised questions about the greenhouse gas(GHG)intensity of these pellets and their effects on conventional forest product markets in the US. This paper examines the GHG intensity of pellets exported from the US using either forest biomass only or forest and agricultural biomass combined.

Over two centuries of economic growth have put undeniable pressure on the ecological systems that underpin human well-being. While it is agreed that these pressures are increasing, views divide on how they may be alleviated. Some suggest technological advances will automatically keep us from transgressing key environmental thresholds; others that policy reform can reconcile economic and ecological goals; while a third school argues that only a fundamental shift in societal values can keep human demands within the Earth’s ecological limits.

Air pollution today is the most important aspect of environmental study as every progress by mankind has deteriorated the air quality. Artificial technologies have proved insufficient to address this problem. So a better and a natural way to combat the air pollution is plantation. However, all plants do not show the same response to a particular type of pollutant. Hence, all plants cannot remediate all kinds of air pollution. There are various parameters on which plant species are selected for plantation viz. APTI, API, dust accumulating potential, carbon sequestering potential etc.

North East India (NEI) has 17.2 M ha under forest cover, which is ~25% of India’s total forest area. Of the total forest cover, 1.5 M ha is currently managed by shifting cultivation in NEI. Shifting cultivation, an integral part of culture and tradition of tribes of NEI, is presently unsustainable because of the populationdriven reduction in the duration of the fallow cycle (3–5 years).
