Not only does the last 30 years or so, appeared to offer outstanding solutions it include species which grow where virtually nothing else to the land use problems of the tropical and the developing will, it also produces food and a high quality wood for fuel world. Various eucalyptus, tropical and subtropical pines, and many other purposes. On the other hand its very vigour Leucaena leucocephala (‘ipil-ipil’) are just a few that have and competitiveness makes it a formidable invader of other captured the stage at different times. The enormous impacts land use systems, such as grazing lands. Furthermore, on human food security that resulted from the green movement of germplasm between countries in the past has revolution suggested to non-foresters and foresters alike that not always been well-documented, so there is often some there must be potentially similar increases in yield available doubt about the original source and sometimes even about from the identification and cultivation of hitherto little- the identity of the species concerned. known trees. A major difference between plantation and agroforestry and irrigated agriculture, of course, was that The authors of this exhaustive text on the Prosopis juliflora - there were many more species of tree than of staple food Prosopis pallida complex have produced an information source crops. A result of this has been a concentration of research which is a landmark in the clarification of many of these effort on provenance or land race selection rather than issues. No book is the final word on its subject but this one genetic improvement, with some notable exceptions. But should last a long time and provide a vital and accessible ‘miracle’ trees, as the authors of this monograph remind us, source of information for scientists, managers, farmers, have remained elusive. And introductions and trials of exotic foresters and students. As for the future of the genus and species and provenances have not only provided evidence this particular species complex, its continuing contribution of rapid growth but have also highlighted risks of them to human welfare will depend on usable knowledge and its becoming noxious weeds. There is thus a conflict between a application, which is the basis of wise management.
