The German Development Bank KfW’s annual international Development Finance Forum will this year focus on the world’s oceans: Oceans 21 -Solutions for a sustainable marine future. Professor David C Wilson has been invited as the opening keynote speaker on one of the three parallel strands of the Forum, focusing on marine litter and marine plastics. The working hypothesis is that avoiding marine litter requires predominantly measures to reduce land-based sources, and of these the largest contributor by weight is inadequate solid waste management in low and middle income countries. DCW will suggest that extending waste collection to all, and eliminating open dumping of wastes, in these countries would likely reduce plastics entering the oceans by more than half. More details will follow the Forum, which is to be held in Frankfurt on 21-22 November 2017.
