Question raised in Lok Sabha on Carbon Capture Sequestration, 29/11/2016.

Humans have altered terrestrial ecosystems for millennia, yet wilderness areas still remain as vital refugia where natural ecological and evolutionary processes operate with minimal human disturbance, underpinning key regional- and planetary-scale functions.

REDD+, agroforestry systems have the potential to reduce deforestation and forest degradation directly and indirectly. They supply timber and fuel wood that would otherwise be sourced from adjacent forests.

As many countries are increasing commitments to address climate change, national governments are exploring how they could best reduce the impact of their greenhouse gas (GHG) emissions. Agriculture is a major contributor to GHG emissions, especially in developing countries, where this sector accounts for an average of 35% of all GHG emissions.

A new report quantifies the carbon stored aboveground in tropical forests that are legally owned or traditionally held by Indigenous Peoples and local communities in 37 countries across tropical America, Africa, and Asia.

Analysis of observations and model projections provides large-scale emergent constraints on the extent of CO2 fertilization, with estimated increases in gross primary productivity for both high-latitude and extratropical ecosystems under elevated atmospheric CO2 concentrations.

A new report offers evidence that the modest investments needed to secure land rights for indigenous communities will generate billions in returns—economically, socially and environmentally—for local communities and the world’s changing climate.

This review summarizes current knowledge on the potential of ecosystems beyond terrestrial forests to contribute to climate change mitigation.

Storing carbon in land is no substitute for reducing fossil fuel emissions. The report finds that while increasing carbon in land systems is important, Australia is muddying the waters by combining land carbon and fossil fuel reduction policies – which is giving an inaccurate picture of Australia’s progress in tackling climate change.

Revegetation of degraded ecosystems provides opportunities for carbon sequestration and bioenergy production. However, vegetation expansion in water-limited areas creates potentially conflicting demands for water between the ecosystem and humans. Current understanding of these competing demands is still limited. Here, we study the semi-arid Loess Plateau in China, where the ‘Grain to Green’ large-scale revegetation programme has been in operation since 1999.
