France, March 14 -- British social scientist and environmental campaigner Rob Hopkins tells RFI that many of the most effective responses to climate change are emerging at the local level - led by citizens, cooperatives and city authorities.

Twenty years ago he helped launch the international Transition Towns movement in Totnes, a town in south-west England, encouraging communities to respond locally to climate change and rising energy costs.

Although he has since stepped back from the organisation, Hopkins remains an influential voice for citizens looking for practical ways to reshape their cities and neighbourhoods.
