Feeding South-East Asia's rapidly growing population requires a second Green Revolution, says Crispin Maslog.

Farmers are more likely to use GM crops if they are involved in crop development in the right way, say Obidimma Ezezika and Justin Mabeya.

The scientific community should create new intergovernmental organisations that promote innovative science in Africa, says Calestous Juma.

Neither dispassionate information nor scare stories are the answer: we need public engagement on health interventions, argues Priya Shetty.

Nigeria must pass a biosafety law so the country's farmers can reap the benefits of GM technology, says Ademola A. Adenle.

With traditional food production under threat from climate change, we should switch from agriculture to cell culture, says Lucía Atehortúa.

A proposed GM policy sent to members of COMESA could make approval of GM crops much easier says an editorial in Nature.

Drought-tolerant crops could improve food security — if researchers take downstream adoption challenges seriously, says Travis Lybbert.

GM production is up, but that doesn't mean Latin Americans like or want it, say Luisa Massarani, Ildeu de Castro Moreira and Ana Maria Vara.

'Appropriate' technologies, no matter where they come from, are the key to improving agriculture, says development expert Sara Delaney.

New biofuels offer a sustainable source of energy but we must consider the ethical and social implications, say Joyce Tait and Banji Oyelaran-Oyeyinka.

Increasing production in mixed crop-livestock systems would improve food security, say M. Herrero and colleagues.

GM crops have been hailed as a 'pro-poor' technology, but the reality is much more complicated, says technology researcher Dominic Glover.

A comprehensive and interconnected global strategy is needed to ensure sustainable food security, say H. Charles J. Godfray and colleagues.

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

Weeding, which causes problems for women in developing countries, can benefit from modern biotechnology, says Jonathan Gressel.

Six experts, writing in The New York Times, discuss options for ensuring food security in the face of growing populations and climate change.

CGIAR reforms take research decisions too far away, says Hartmann, director-general of the International Institute of Tropical Agriculture (IITA).

Intellectual property must be protected to encourage technical innovations in agriculture, says Javier Fernandez of CropLife Latin America.

Moves to introduce biotechnology to Africa must consider the needs and values of local people, argues socioeconomist Wilhemina Quaye.
