Journalists can help the developed world take responsibility for climate change by making it relevant to readers' lives, says David Dickson.

We need to understand why some people act on early warnings while others ignore them, says disaster preparedness specialist Sudhir Kumar.

We need to know more about how smallholder agroforestry can help farmers adapt to climate change, write James Roshetko and Rodel Lasco.

More Asia–Pacific countries need to embrace renewable energy and follow the first tentative steps of some governments, says Crispin Maslog.

Using the human rights framework to tackle challenging ethical questions can guide climate policy, argues political philosopher Simon Caney.

Algal biofuels, like crops, demand land, water, fertilisers, pesticides and inputs that are costly for India, says Hoysall Chanakya.

Sustainable development targets will work only if they engage with the realities of national politics, says policy expert Matthew Lockwood.

Forecast to be underwater by 2050, the Pacific island states must plan for climate adaptation, with global support, urges Crispin Maslog.

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.
