This is the first of a series of three volumes of Source Books on Environmental Planning and Management (EPM). Volume 1, "Implementing the Urban Environment Agenda" is a carefully designed, user-friendly guide on how to carry out each stage in the process of developing urban environmental priorities, strategies and action plans. Based on the experiences of more than 450 city practitioners and partners from more than 75 cities and 20 international support programmes, the book is illustrated with examples of city practices drawn from almost 50 specially-commissioned case studies.
