&i;`The `new economics' has been long in moral argument and grass roots activity. But it has made much less progress toward developing new measurement tools that are appropriate to its goals - sustainable, `green' and human-centred development. This is the first set of truly practical proposals in this vital area of analysis. The book is sure to cause a stir among development economists, environmental activists, and others looking for better signposts in an uncertain world.'&o; Ian Miles, University of Manchester.
