Whilst providing clean power, building a dam has significant environmental impacts. Ercan Ayboga is a campaigner with the Save Hasankeyf movement, and tells us why his organisation hoped to prevent the Turkish town of Hasankeyf being flooded by a dam project. Dr Barnaby Dye of Manchester University works with the Future Dams International research consortium, and discusses best practice in dam building. And Pai Deetes is a campaigner with International Rivers, who questions the purported benefits of dam construction for people local to new projects. Also in the programme, French carmaker Renault has replaced its chief executive with immediate effect. Our reporter Theo Leggett tells us what was behind the move. Plus as voters in Poland prepare to head to the polls this weekend, we take a look at the economic issues that have emerged during the campaign.
