European Union countries need to significantly increase investments in carbon capture and storage and show much greater urgency and determination to develop and deploy the technology, according to a new report by the Grantham Research Institute on Climate Change and the Environment at London School of Economics and Political Science and the Gran

Diatoms are responsible for ~40% of marine primary productivity, fuelling the oceanic carbon cycle and contributing to natural carbon sequestration in the deep ocean. Diatoms rely on energetically expensive carbon concentrating mechanisms (CCMs) to fix carbon efficiently at modern levels of CO2. How diatoms may respond over the short and long term to rising atmospheric CO2 remains an open question.

Studies on measuring CO2, CH4 and N2O fluxes from five agroforestry systems viz., teak, jatropha, pongamia, simaruba and leucaena were conducted in semi-arid alfisols. This study gives an idea of successive potential values of GHGs in agroforestry systems to compare with carbon sequesteration abilities of these systems.

Riverine export of particulate organic carbon (POC) to the ocean affects the atmospheric carbon inventory over a broad range of timescales. On geological timescales, the balance between sequestration of POC from the terrestrial biosphere and oxidation of rock-derived (petrogenic) organic carbon sets the magnitude of the atmospheric carbon and oxygen reservoirs. Over shorter timescales, variations in the rate of exchange between carbon reservoirs, such as soils and marine sediments, also modulate atmospheric carbon dioxide levels.

LIKE in other countries, stakeholders, who met at the just concluded 7th Climate Change Summit, organised by the Lagos State government has called for a need to create a Green Fund Initiative for t

This study presents the findings of research into the global socio-economic and environmental impact of genetically modified (GM) crops in the eighteen years since they were first commercially planted on a significant area.

Despite a large increase in the area of selectively logged tropical forest worldwide, the carbon stored in deadwood across a tropical forest degradation gradient at the landscape scale remains poorly documented. Many carbon stock studies have either focused exclusively on live standing biomass or have been carried out in primary forests that are unaffected by logging, despite the fact that coarse woody debris (deadwood with ≥10 cm diameter) can contain significant portions of a forest's carbon stock.

The VOLANTE Roadmap for Future Land Resources Management in Europe is a tool for policymakers and practitioners alike. It features three visions of future land use, created in a participatory process by a set of stakeholders from all across Europe.

Using the case of Costa Rica, this paper examines how 'carbon' became an identifiable problem for that state. We trace how, during the 1980s, rationalities of financialisation and security arose in this country that allowed for Payments for Ecosystem Services (PES) to emerge as an economic and political mechanism. Our central thesis is: this period initiated a government project of securing a viable future for the nation's resources by linking them to global financial markets and international trade.

Ensuring that the world's food needs are met by 2050 will take a doubling of global food production. To improve agricultural yields on that scale will require a radical rethink of global water-management strategies and policies. Sub-Saharan Africa is the epicentre of this challenge. Ninety-five per cent of sub-Saharan agriculture depends on 'green water': moisture from rain held in the soil. In large parts of the continent, most rain evaporates before it generates 'blue water', or run-off, so little of it recharges rivers, lakes and groundwater.
