Agro-ecology offers simple solutions and can align climate change with food security agendas, says UN adviser Olivier De Schutter.

Josette Sheeran, executive director of the UN World Food Programme, argues for programmes that build sustainable food security.

The East Africa famine calls into question the wisdom of investing in early warning systems without improving take-up, writes Linda Nordling.

Success stories show that food crises can be controlled with the right tools and agricultural policies, says Sam Dryden.

We must find a better way of monitoring the impact of food insecurity, argues Derek D. Headey.

The current drought in northern Kenya has deep roots in the current practices of pastoralists that need to be addressed, says conservationist David Western.

Combined strategies are needed to meet the world's rising demands for food without further damage to biodiversity, says Jason Clay.

Assessments of bioenergy must consider the potential benefits for rural development and food security, say Lee R. Lynd and Jeremy Woods.

Past successes, such as the Green Revolution, can inform future priorities in agriculture, say David J. Spielman and Rajul Pandya-Lorch.

A conflict between climate adaptation and food security policies shows we must create the right conditions for change, says Blessings Chinsinga.

Developing countries need help with crop surveillance and the development of strains resistant to wheat rust, say agricultural research leaders.

We need a "new agriculture" and "new conservation" to feed the world's population and protect ecosystems, says Achim Steiner.

Disaster specialists must gather and analyse data systematically to prevent human stampedes, say Frederick M. Burkle and Edbert B. Hsu.

Development economist Lawrence Haddad argues that improving nutrition can, and should, be a central goal of agriculture.

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

Small-scale water solutions are a key to increasing agricultural productivity in the face of climate change, says water expert David Molden.

Coping with climate change requires a greater understanding of the options for water storage, writes hydrology expert Matthew McCartney.

Agriculture and health experts must work together to tackle disease, poverty and malnutrition, says development expert Jeff Waage.

A team of agriculture and environment experts, led by Jeffrey Sachs, call for a global network to monitor the world's farming systems.

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