Rapid advances and new technologies in the life sciences – such as biotechnologies in health, agricultural and environmental arenas – pose a range of pressing challenges to questions of citizenship. This volume brings together for the first time authors from diverse experiences and analytical traditions, encouraging a conversation between science and technology and development studies around issues of science, citizenship and globalisation. It reflects on the nature of expertise; the framing of knowledge; processes of public engagement; and issues of rights, justice and democracy. A wide variety of pressing issues is explored, such as medical genetics, agricultural biotechnology, occupational health and HIV/AIDS.
