Sustainable development has grown to encompass cultural, socio-economic, political and environmental issues, and the use of sustainability indicators (SIs) is seen by many as central to its implementation - after all, how can one "do" sustainable development unless one knows when it has been attained? The adoption of SIs in such a context is logical, but does present a number of practical difficulties. So far, much of the published material consists of theoretical SI frameworks, with little practical experience on their use in development scenarios. In contrast, this volume is based on the results of a six-year project designed to develop and evaluate the use of SIs in a Nigerian village. It takes into consideration the views and perspectives of the local population, and in doing so addresses key issues that are vital for anyone attempting to put sustainable development into practice.
