The Ecology of Wisdom is a definitive collection of essays by Norwegian philosopher Arne Naess, a founder of the Deep Ecology movement and one of the leading thinkers of modern environmentalism. Drengson and Devall provide a comprehensive and accessible portrait of Naess's philosophy and activism, and showcase his enthusiasm, wit, and spiritual fascination with nature.

This book offers an introduction to the theory and practice of ecological wisdom (EW). EW is the integration of robust contemporary science with proven cultural and historical practices to identify long-term, sustainable solutions to problems of environmental management and urban design. The book combines theoretical concepts with specific case studies, illustrating the opportunities for interdisciplinary approaches combining historical experience, cultural context, and contemporary science as effective strategies for addressing complex problems confronting metropolitan and rural environmental and resource management in areas such as land use, water management, materials and building engineering, urban planning, and architecture and design. EW transcends the limitations in these fields of the normative approaches of modernity or traditional wisdom by offering a new, synthetic strategy to address socio-ecological issues. By presenting these ideas both theoretically and through existing case studies, the book provides researchers, practitioners and students with a powerful new perspective in developing long-term, resilient solutions to existing socio-environmental challenges. It is intended mainly for those working or interested in the fields of sustainable environmental and resource management, city and regional planning, architecture and design, civil engineering, landscape architecture, and the philosophy of science, particularly those with an ecological or sustainability focus.

Deep Ecology explores the philosophical, psychological, and sociological roots of today's environmental movement, examines the human-centered assumptions behind most approaches to nature, explores the possibilities of an expanded human consciousness, and offers specific direct action suggestions for individuals to practice. Widely read in it first printing, Deep Ecology has established itself as one of the most significant books on environmental thought to appear in this decade. "Deep Ecology is subversive, but it's the kind of subversion we can use." --San Francisco Chronicle "This book is an attempt at codifying a scattered body of ecological insight into a philosophy that places human beings on an absolutely equal footing with all other creatures on the planet." --Stephanie Mills, Whole Earth Review "Difficult and (to some) unfamiliar insights on nature and human beings presented with simplicity and clarity, Deep Ecology rattles a cage full of occidental presumptions and yet it all seems almost like common sense." --Gary Snyder

A founder of the Deep Ecology Movement, Arne Naess' has produced articles on environmentalism that have provided unmatched inspiration for ecologists, philosophers, and activists worldwide. This collection amasses a definitive group of Naess' most important works in which he calls for nonviolent, cooperative action to protect the Earth. Rich with observations, insights, and anecdotes, Naess' writings draw from Eastern religious practices, Gandhian nonviolent direct action, and Spinozan unity systems. Playful and compassionate in tone, Ecology of Wisdom showcases Naess' exceptional enthusiasm, wit, and spiritual fascination with nature, while educating each of us about the steps we must take to rescue the planet and illuminating the relevance of this important environmental advocate.

There has been a proliferation of publications in the field of Christian ecological theology over the last three decades or so. These include a number of recent edited volumes, each covering a range of topics and consolidating many of the emerging insights in ecological theology. The call for Christian churches to respond to the environmental crisis has been reiterated numerous times in this vast corpus of literature, also in South Africa.

An understanding of the ecology of a fish pond is essential for the achievement of steady and high fish production in ponds. For the ecologist, the fish pond is a small laboratory: easy to investigate and responding rapidly to manipulation. For the aquaculturist, the ecology shows the ways and means of interventions ensuring an increase of production. The book deals with the different aspects of natural production within a pond, referring it to African conditions: considering first the role of soil as source and sink of nutrients for the water, then nutrient cycling within water and the fate of fertilizers added to ponds, and finally the contribution of natural productivity to fish production. The important sum of information brought together in this volume is valuable for both aquaculturist and ecologist, who lack a handbook on the ecology of a fish pond. It will capture the interest of African aquaculturists and stimulate aquaculture research on natural production.
