        Evaluating Indirect Ecological Effects of Biological Control

        by Edited by Eric Wajnberg, John K Scott, Paul C Quimby

        A major concern for biological control has always been the risk of indirect unwanted effects on the ecology of other organisms. Our understanding of the ecological and evolutionary processes underlying these effects has until now been limited and experimental methods sometimes lacking. This book presents the key papers from of the first International Organisation for Biological Control global symposium, held in Montpellier, France, in October 1999. It addresses the issues and concerns involved in biological control, and assesses the current status of evaluation of the ecological effects.

        Forests and Landscapes

        Linking Ecology, Sustainability and Aesthetics

        by Edited by Eric Wajnberg, John K Scott, Paul C Quimby

        Forests are an important component in the visual appeal of landscapes. There is an increasing recognition of the importance of this subject among foresters and environmental scientists. Increasingly, forest resource managers must consider both the aesthetic consequences of timber harvesting operations and management plans and public perceptions of the sustainability of forest eco-system management.Written by world class authorities this book is the first to address this subject area. It consists of 17 chapters and is divided into six parts. The interdisciplinary nature of the book brings together not only foresters and ecologists, but also landscape architects, psychologists and philosophers. Contributors are leading research workers in their subjects, from Canada, the USA and UK.

        Global Rangelands

        Progress and Prospects

        by Anthony C Grice, Ken C Hodgkinson

        Although traditionally defined as areas where natural vegetation is exploited for grazing by domestic and native herbivores, rangelands are used by many different people, for a host of purposes. As well as livestock products, rangelands provide fuels, minerals and water and are used for ecotourism, recreation, nature conservation and as carbon sinks. More than half of the earth's land surface is rangeland and millions of people, both within and outside the rangelands, depend on them. This book addresses the important issues confronting the rangelands and presents new concepts and approaches for the management of rangeland resources. It is relevant to the people who live in or depend on the rangelands, and to the institutions and organisations that support them.

        Sustainable Management of Soil Organic Matter

        by Edited by Robert M Rees, B Ball, C Watson, C D Campbell

        Includes some fifty edited and revised papers from an international conference on Sustainable Management of Soil Organic Matter, held by the British Society of Soil Science in Edinburgh in September 1999. The book explores the results of recent research studies examining how organic matter functions in soils, factors affecting organic matter quality and quantity and how management of organic matter can be optimised in order to achieve sustainable farming practices.

        Friedrich Schiller

        by Volker C. Dörr, Volker C. Dörr

        In einer Zeit großer politischer Umwälzungen, in Sorge um seine finanzielle Existenz, von Krankheit gezeichnet, schrieb Friedrich Schiller Literatur, die von der Spannung zwischen dem Ideal und dem Leben geprägt ist. Längst sind seine Werke kanonisch geworden, sie werden viel gelesen, oft parodiert und noch häufiger verkürzt – auf die berühmten Dichterworte über das Wahre, Gute, Schöne.

        Managing Risk in Agriculture

        A Development Perspective

        by Ashok K. Mishra, Subal C. Kumbhakar, Gudbrand Lien

        The book addresses and documents farmers' risks in developing and emerging economies. It draws lessons from experimental economics on measuring risk preferences, attitudes, gender differences in managing risks, and risk management strategies in countries across Africa and Asia. It argues policy makers, especially in emerging economies, need a better understanding of farmers' attitudes toward risk and choices of risk management strategies when designing policies to support production agriculture. The book includes chapters on three themes: understanding risk attitudes and preferences; using experimental economics to measure risk, preferences, and risk management strategies; and understanding climate change, risk, and risk management. The book critically examines the currently held beliefs about risk preference, attitudes, and empirical estimation of risk management strategies, emphasizing developing and emerging economies (DEE). "The agricultural development space is an inherently risky one and this welcome collection belatedly helps to plug an important hole." Jock R. Anderson, Emeritus Professor of Agricultural Economics, University of New England, Armidale, Australia "Over time, agricultural production practices have evolved, as have the markets and value chains for food and agricultural products. A constant consideration, however, and one that continues to define agriculture worldwide, is risk. The risks that impinge on agriculture come in all shapes and sizes. Of course, production risks are ubiquitous. But so are market risks. And the same is true for macroeconomic and financial risks and the risks associated with an evolving climate. This book will be a valuable, comprehensive resource for any applied economist desiring to understand the risk management principles relevant to modern food and agricultural systems." Matthew Holt, Prof. and head of the Department of Agricultural and Applied Economics, Virginia Tech University, Blacksburg, VA, USA.
