The volume also contains papers that are the product of two nexus observatory workshops that were organized by UNU-FLORES in Dar es Salaam and New Delhi. The volume contains some case studies from Asia, Africa and Europe that add to the policy relevance of the book. The editors acknowledge the contribution of subject matter experts drawn from different disciplinary backgrounds and pro- fessional experience who have contributed towards writing and then revising their chapters to meet the highest standards of research and publishing quality. Leslie O’Brien (our language and copy editor) and Kristin Meyer at UNU-FLORES worked painstakingly to ensure that the manuscripts met the deadline and pub- lishing guidelines of Springer.

Source EEA (2013). Notes Primary (mechanical) treatment removes part of the suspended solids. Secondary (biological) treatment uses aerobic or anaerobic microorganisms to decompose most of the organic matter and retain some of the nutrients (around 20–30 %). Tertiary (advanced) treatment removes the organic matter even more efficiently and generally includes phosphorus retention and in some cases nitrogen removal.
