The workshop "Environmental Change and Malaria Risk: Global and Local Implications" was held to conclude a 5-year collaborative research project on environmental change and malaria risk, with field research in Kenya and Brazil. It was fitting that such a large group of specialists was able to attend the workshop and contribute with a chapter in which the predicted environmental changes were viewed from different angles. We would like to thank the Netherlands Foundation for the Advancement of Tropical Research (WOTRO) and the National Programme for Research on Climate Change and Air Quality (NOP) for having funded our work so generously. Wageningen UR - Frontis is thanked for having arranged the workshop and for its financial contribution. We would especially like to thank Petra van Boetzelaer for having assisted with the logistics of the workshop, and Paulien van Vredendaal for having spent many hours in the type editing of the chapters, making publication of this book possible.
