Efforts to protect precious marine biodiversity by combining science and local knowledge are difficult but can work, reports Naomi Antony.

SciDev.Net talks to Sylvia Earle, scientist, oceanographer, explorer, about her hopes for oceans at the Rio+20 conference in Brazil in 2012.

The cities account for more than three quarters of emissions of CO2, are home to half the world population and will be 'highly visible' at Rio +20.

Andreas Schild of the International Centre for Integrated Mountain Development talks to SciDev.Net about glacial retreat.

Priya Shetty explains the links between climate change and insect-borne disease, and outlines priorities for developing country policymakers.

Modelling how climate change might affect insect-borne disease is hugely complex — and increasingly controversial, explains Justine Davies.

Climate change is a reality in developing regions, who say the international community must not neglect better adaptation strategies.

Hannah Chalmers gives the low-down on how reducing emissions from deforestation can play a central role in tackling climate change.

The Tibetan plateau is feeling the effects of climate change, with glacial retreat and permafrost degradation among the effects.

The UN supports forest protection in the next climate agreement, but questions on how to tackle deforestation are still being debated.
