This document presents a collection of selected papers produced for and discussed at the Second International Conference on Early Warning, in Bonn, Germany, in 2003, and four regional conferences in Africa, Asia/Pacific, America and Europe. The conferences focused on integrating early warning into sustainable development policy. The document notes the failure of scientists, policymakers, local authorities and other relevant actors to use early warning systems efficiently, and makes suggestions for improvement. It highlights challenges, lessons learnt and possible trajectories for further development of early warning systems, and outlines key steps towards strengthening frameworks, finding resources, and designating responsibilities. Key areas for action include improving data collection, ensuring that warning systems focus on people and achieve gender balance, and creating platforms for early warning dialogue.

This peer-reviewed paper examines the factors that motivate people to innovate, with the authors arguing that material rewards, such as capital or patents, make up only one aspect of their motivation. Using grassroots innovation in India as a case-study, the study found that the intrinsic rewards of "getting things done" and satisfaction play just as important a role as extrinsic factors, such as increased income.

The authors developed indicators of motivation by looking at innovation as a process of three stages — idea generation, experimentation and application. They found that intrinsic motivations were particularly important in the early stages, when there are high levels of uncertainty about the innovation. They conclude by outlining implications of their findings for innovation policies, suggesting that use of funding and patents could negatively impact innovators by reducing their desire to share their ideas locally.

This essay by Chunli Bai, executive vice president of the Chinese Academy of Sciences (CAS), explains the reasons behind the rapid progress of nanotechnology in China. A key factor, says Bai, has been "extraordinary" government support for the field since the early 1980s, which led to the creation of research institutes and significant grant money. But, cautions Bai, public communication on nanotechnology research, and ongoing monitoring and assessment of nanotechnology risks is needed.

This paper considers the potential role of 'innovation brokers' — intermediary organisations that help build links in innovation systems and facilitate multi-stakeholder interaction — in developing countries' agriculture. The authors suggest that to encourage organisations to take on this role, policies that encourage institutional learning and experimentation must be put in place. A first step must be mapping the strengths and weaknesses of the existing innovation system.
