The provision of public goods such as education, electricity, health, sanitation, and water used to be regarded as primarily the responsibility of governments, but in the 1980s privatization of such services spread and reliance on market mechanisms instead of governments became common in many parts of the world, including developing countries. The record of the past twenty-five years of market-led development, however, has not been encouraging. Not only has it failed to improve public services significantly, but it has also undermined democratic institutions and processes, reproduced authoritarian relations of power, and suppressed alternatives made possible by an increasing global acceptance of the importance of economic and social rights. In Limiting Resources, LaDawn Haglund seeks an understanding of public goods that can better serve the needs of people in developing countries today. Haglund critiques the narrow conception of public goods used in economics, which tends to limit the range of resources considered “public,” and proposes an expanded conception drawing from multiple disciplines that incorporates issues of justice, inclusion, and sustainability. She then uses case studies of electricity and water provision in Central America to illuminate the conditions for success and the causes of failure in constructing adequate mechanisms for the supply of public goods. She follows with an analysis of political conflicts over privatization that reveals how neoliberal policies have made effective state action difficult. The book concludes with suggestions for ways in which this reformulated conception of public goods can be applied to promote justice, sustainability, and economic and social rights in developing countries.
Examines the factors which limit human economic and population growth and outlines the steps necessary for achieving a balance between population and production. Bibliogs
One of the central questions of ecology is why there are so many different kinds of plants and animals. Here David Tilman presents a theory of how organisms compete for resources and the way their competition promotes diversity. Developing Hutchinson's suggestion that the main cause of diversity is the feeding relations of species, this book builds a mechanistic, resource-based explanation of the structure and functioning of ecological communities. In a detailed analysis of the Park Grass Experiments at the Rothamsted Experimental Station in England, the author demonstrates that the dramatic results of these 120 years of experimentation are consistent with his theory, as are observations in many other natural communities. The consumer-resource approach of this book is applicable to both animal and plant communities, but the majority of Professor Tilman's discussion concentrates on the structure of plant communities. All theoretical arguments are developed graphically, and formal mathematics is kept to a minimum. The final chapters of the book provide some testable speculations about resources and animal communities and explore such problems as the evolution of "super species," the differences between plant and animal community diversity patterns, and the cause of plant succession.
Shifting cultivation is the predominant system of arable farming in the humid and sub-humid tropics, where several hundred million people depend on this system of agriculture for their livelihood. This book documents and systematizes findings in shifting cultivation from over the last six decades, including characterizing secondary succession and relating the changes that fallow vegetation undergoes to the process of soil fertility restoration. This book is essential reading for researchers and students of tropical agriculture and related areas.

Despite claims to the contrary, the science of ecology has a long history of building theories. Many ecological theories are mathematical, computational, or statistical, though, and rarely have attempts been made to organize or extrapolate these models into broader theories. The Theory of Ecology brings together some of the most respected and creative theoretical ecologists of this era to advance a comprehensive, conceptual articulation of ecological theories. The contributors cover a wide range of topics, from ecological niche theory to population dynamic theory to island biogeography theory. Collectively, the chapters ably demonstrate how theory in ecology accounts for observations about the natural world and how models provide predictive understandings. It organizes these models into constitutive domains that highlight the strengths and weaknesses of ecological understanding. This book is a milestone in ecological theory and is certain to motivate future empirical and theoretical work in one of the most exciting and active domains of the life sciences.

Butterflyfishes of the family Chaetodontidae are conspicuous members of almost all tropical reefs. These colorful fishes have attracted a great deal of attention from both the scientific community and especially the aquarium fish industry. At first one is tempted to say that butterflyfishes are abundant worldwide, but the evidence does not support this statement. The biomass of chaetodontids on reefs may range from 0.02-0.80%, and in terms of numbers they comprise only 0.04-0.61 % of the individuals on the reef. Yet in spite of these relatively small numbers they have been extensively studied. A quick census shows some 170 articles on or about butterfly fishes, with 78% of them being published since the 1970's. Along with the cichlids and damselfishes they might be one of the most studied and well published family of tropical fishes. Why then have chaetodontids attracted so much attention? The butterflyfishes are mostly shallow water inhabitants that are approachable and easily recognizable, making their study very feasible. Their bright coloration has provoked many hypotheses but has posed more questions about coloration than it has provided answers. And despite their apparent overall morphological similarity, their highly structured and varied social systems have made them an ideal model for such studies. The reasons for choosing these organisms are indeed as diverse as the studies themselves.
The realization of a successful product requires collaboration between developers and producers, taking account of stakeholder value, reinforcing the contribution of industry to society and enhancing the wellbeing of workers while respecting planetary boundaries. Founded in 2006, the Swedish Production Academy (SPA) aims to drive and develop production research and education and to increase cooperation within the production area. This book presents the proceedings of the 10th Swedish Production Symposium (SPS2022), held in Skövde, Sweden, from 26-29 April 2022. The overall theme of the symposium was ‘Industry 5.0 Transformation – Towards a Sustainable, Human-Centric, and Resilient Production’. Since its inception in 2007, the purpose of SPS has been to facilitate an event at which members and interested participants from industry and academia can meet to exchange ideas. The 69 papers accepted for presentation here are grouped into ten sections: resource-efficient production; flexible production; humans in the production system; circular production systems and maintenance; integrated product and production development; industrial optimization and decision-making; cyber-physical production systems and digital twins; innovative production processes and additive manufacturing; smart and resilient supply chains; and linking research and education. Also included are three sections covering the Special Sessions at SPS2022: artificial intelligence and industrial analytics in industry 4.0; development of resilient and sustainable production systems; and boundary crossing and boundary objects in product and production development. The book will be of interest to all those involved in the development and production of future products.
Features review questions at the end of each chapter; Includes suggestions for recommended reading; Provides a glossary of ecological terms; Has a wide audience as a textbook for advanced undergraduate students, graduate students and as a reference for practicing scientists from a wide array of disciplines
