This groundbreaking book provides a comparative perspective on water management and federalism across multiple countries. Through a collection of case studies, this book explores the water management experiences and lessons learned in nine federal countries and China. The territorial division of power in federations, plus the interconnected politics at the national and regional levels, present a classic governance test for waters shared across multiple political jurisdictions. This is increasingly important as democratic transitions have introduced or invigorated federalism across diverse contexts affecting more than 300 major river basins.Federal Rivers examines both the successes and failures of federal regimes in resolving water conflicts and achieving sustainable water management, particularly within river basins. Case studies across the Americas, Asia, Africa, Europe and Australia highlight the extent and diversity of federal rivers, identifying alternative pathways to sharerisks and make tradeoffs across political jurisdictions.This book will appeal not only to scholars of resource management and of federalism, but also to practitioners in government, the private sector and international networks with interests in water policy and federalism.

for the design of control programs; in extreme cases (as dis cussed below, by Fine et al., this volume, and elsewhere) it can happen that immunization programs, although they protect vaccinated individuals, actually increase the overall incidence of a particular disease. The possibility that many nonhuman animal populations may be regulated by parasitic infections is another topic where it may be argued that conventional disciplinary boundaries have retarded investigation. While much ecological research has been devoted to exploring the extent to which competition or predator-prey interactions may regulate natural populations or set their patterns of geographical distribution, few substan tial studies have considered the possibility that infectious diseases may serve as regulatory agents (1,8). On the other hand, the many careful epidemiological studies of the trans mission and maintenance of parasitic infections in human and other animal populations usually assume the host population density to be set by other considerations, and not dynamically engaged with the disease (see, for example, (1,2)). With all these considerations in mind, the Dahlem Workshop from which this book derives aimed to weave strands together -- testing theoretical analysis against empirical facts and patterns, and identifying outstanding problems -- in pursuit of a better un derstanding of the overall population biology of parasitic in fections. For the purpose of the workshop, the term "parasite" was de fined widely to include viruses, bacteria, protozoans, fungi, and helminths."
