Prior to the twentieth century, most environmental observations such as rainfall amounts and air temperatures were made by lay observers with interest and time on their hands. Later on, such measurements moved largely into the realms of professionals, but today the role of amateur observers is being revisited. The advent of smartphones and GPS is increasingly allowing citizen observers of wildlife, ecology, air and water quality, and flooding, to enhance our understanding of environmental science. What opportunities exist for individuals to help to solve some of the most complex problems on Earth? And what motivates people to join an environmental research team?

Professor Carolyn Roberts is the first Frank Jackson Professor of the Environment at Gresham College. She is also a Senior Scientist at the UK Knowledge Transfer Network (KTN), which links business and universities in order to promote research and innovation in environmental technologies. (from
