• In our report on Lake Victoria (11 February, p 12) we identified Daniel Kull as a hydrologist with the UN’s International Strategy for Disaster Reduction in Nairobi, Kenya, and as the author of a report released by the California-based environmental lobby group International Rivers Network. This may have created the impression that Kull wrote the report in his capacity as a consultant to the UN. We would like to clarify that Kull wrote the report for IRN as a private citizen, and we regret any confusion caused.
