This report examines specific water harvesting systems in sub-Saharan Africa. Case studies of thirteen systems from six different countries are presented, and conclusions are drawn under the headings of techniques and engineering, production, socio-economic and project management aspects. A number of projects throughout the region, set up in the 1980's, have included water harvesting components. However, there is a wide range of techniques, approaches and costs - and the impact of these projects varies considerably. The majority of systems introduced are for crop production, but there are examples of water harvesting to establish trees in dry areas and for rehabilitation of grazing land also. The need for voluntary participation in all stages of project development is highlighted. It is evident that without this participation there is little or no chance of widespread adoption. The importance of indigenous systems of water harvesting, and their potential role as a base for planning, is stressed in the conclusions.
Effectively diagnose the complete range of pediatric pathologies, from neonatal disorders through adolescence. Intended for a broad audience including general and pediatric pathologists, pediatricians, surgeons, oncologists, and other pediatric subspecialties, Stocker & Dehner’s Pediatric Pathology is widely recognized as the definitive go-to comprehensive clinical reference in the unique subspecialty of pediatric pathology – which, unlike other subspecialties, is defined by an age group rather than an organ system or process. The tumors that occur in infants and children are distinct from those that develop in adults, and they often exhibit exceptional clinical behavior, thus requiring different diagnostic and therapeutic protocols. Authored by a host of prominent authorities on this challenging area, the fourth edition of Stocker & Dehner’s Pediatric Pathology was designed to be a comprehensive volume on all major aspects of the pathologic anatomy of childhood disorders, providing the in-depth, richly illustrated guidance you need to confidently evaluate and dependably report your findings. Sweeping updates in this edition put all of the very latest knowledge and techniques at your fingertips.
