This collection of features and commentaries, published by Nature, reflects the broad spectrum of activities and opinions of members and associates of TWAS, the academy of sciences for the developing world.

With more than three dozen articles written by prominent scientists working on research or policy issues in the South, the collection examines a range of topics in science-based international development — from the relevance of subjects like mathematics or physics, to the increasing roles of biotechnology and renewable energy.

The achievements made and challenges still facing developing countries in key areas like agriculture, health, climate change and energy are also discussed. And evidence from across the South is presented to show how strengthening science can help achieve economic goals and what more is needed to ensure that knowledge and development are shared by all.
