Peter Messerli and colleagues argue that reforms in agricultural policy will be needed to build green economies in the developing world.

Improving access to information technology can help communities assess their own vulnerability and boost local planning, says John Waugh.

Business models that pair up cheap solar technologies with cell-phone services can provide the poor with renewable energy, says Carl Pope.

Africa must make sure its grassroots innovations can benefit from a new global green technology support mechanism, argues Linda Nordling.

Analysing vulnerability to climate change must go beyond stating obvious problems to become truly useful, argues Marcus Moench.

A new southern African climate plan is impressive, but needs more funding if it is to plug the continent's data gap, writes Linda Nordling.

Cities are vulnerable to climate change but can adapt with policymaking informed by sound science says Cynthia Rosenweig and colleagues.

Policymakers must find flexible plans to ensure water security despite the uncertainties of climate change, says climate scientist Mark New.

The challenge for Latin American and Caribbean governments is to combine an approach to development with low-carbon emissions, says Omar Vidal.

Understanding how carbon dioxide impacts food quality is vital to tackle malnutrition effectively, says agricultural researcher Lewis Ziska.

Governments must centre climate policies around technology development, not emissions targets, say Isabel Galiana and Christopher Green.

Access to clean energy — not emissions reductions — is the key to tackling climate change, say Nancy Birdsall and Arvind Subramanian.

Innovative agricultural technologies can produce crops that meet climate change challenges, says ICRISAT head William Dar.

China is considering a low-carbon road map to reduce emissions while preserving economic growth. Technology is crucial, says Gordon Conway.

Countries must join forces and act quickly to tackle climate change, say Rosina Bierbaum and Robert Zoellick in an editorial in Science.

Practicalities of trading carbon and protecting forests make meeting high expectations for REDD hard, say Esteve Corbera and Manuel Estrada.

Time is running out for African countries to ensure that a global climate deal addresses their needs, says Linda Nordling.

Climate change will make Indian dryland agriculture harder, but a scientific strategy offers real hope, says ICRISAT head William D. Dar.

Action on climate change is key to ensuring sustainable development in Nepal, say activists Gagan Thapa and Kashish Das Shresth.

To get the best for and from Africa, REDD negotiators must hear African viewpoints, says head of the African Forest Forum, Godwin Kowero.
