[email protected] i Foreword As we can read from Risto Seppälä in the IUFRO News Vol. 25, 1996, issue 3, the scientific community has become increasingly interested in sustainability, and IUFRO, to demonstrate this has established a special Task Force on sustainable Management. The following paper is an attempt to give an overview of the recent developments mainly in North America, in the field of sustainable and ecosystem-based management of natural resources, including forest resources. The subject is in line with the actual preoccupation of IUFRO and should be of interest to all division. ii Acknowledgments This paper was written during a sabbatical leave at Oregon State University, Corvallis, Oregon, USA. I am grateful to my host, the Department of Forest Engineering of the College of Forestry, and to the Board of the Swiss Federal Institutes of Technology who made the sabbatical leave possible. During my sabbatical leave I was in the most friendly and competent way guided by Bob Buckman. Very important were the discussions with many colleagues from the Oregon State University (OSU), the U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station, Corvallis, the Oregon Department of Forestry (ODF), the University of Montana, Missoula, and the University of New Brunswick, Fredericton, Canada. I thank the following reviewers for their comments on earlier drafts: Bernard Bormann, Jill Bowling, Jim Boyle, Martha Brookes, Bob Buckman, Steve Hobbs, Logan Norris, George Stankey, Fred Swanson, and Steve Tesch. I also thank IUFRO for accepting the publication of the paper. iii Contents 1. Introduction 1 2. Background and recent developments 2 2.1. International efforts 2 2.2.

The concept of ecosystem management developed recently in the United States is discussed. Principles of managing natural resources for sustainable development are presented. A definition of ecosystem-based management is proposed. Instruments and scientific challenges are identified. A series of questions which should be answered for the implementation of ecosystem-based management are presented. 1. Introduction The idea of using an ecosystem approach in managing natural resources is not new. In the preface of his remarkable book The Ecosystem Concept in Natural Resource Management Van Dyne (1969) wrote: "This volume will be timely because of the widespread interest in ecosystem approaches". The book is based on a symposium held at the annual meeting of the American Society of Range Management in Albuquerque, New Mexico, on February 12-15, 1968. Since then, progress has been realized. However, the world's awareness of the emerging problems due to different pressures on the ecosystems on which our society depend for its well being has increased considerably. It has also become clearer, that plants, animals, microorganisms, soils, air, and water constitute a natural heritage of social, economic, ecological, and intrinsic value that needs to be preserved, where possible enhanced, and handed on to future generations.The need to improve the protection and management of ecosystems in a way that balances and integrates environmental and development questions, is now recognized as an important challenge for sustainable development. This new awareness has led to a series of international and national efforts aimed at assuring the quality of life to both present and future generations. An objective of this paper is to review ideas on how natural resources can be managed for sustainable development. A second objective is to provide a general conceptual framework within which the research and the teaching of the new professorship in Ecosystem Management in the Department of Rural Engineering, Swiss Federal Institute of Technology, Lausanne, can be defined. Although the paper was developed during a sabbatical leave at Oregon State University in Corvallis, USA and is therefore essentially inspired by North American work for forest ecosystems, the described ideas are applicable for other natural resources and in different ecoregions. 2 2. Background and recent developments 2.1 International efforts Five documents resulted from the Earth Summit held in Rio in 1992. • The Rio Declaration on Environment and Development includes 27 principles defining the right and the responsibilities of nations as they pursue human development and well being. The following principles are especially important for management as well as for research: - People are at the centre of concerns for sustainable development. They are entitled to a healthy and productive life in harmony with nature (Principle 1). - The right to development must be fulfilled so as to equitably meet development and environmental needs of present and future generations (Principle 3). - In order to achieve sustainable development, environmental protection shall constitute an integral part of the development process and cannot be considered in isolation from it (Principle 4). - States shall cooperate in a spirit of global partnership to conserve, protect and restore the health and integrity of the Earth's ecosystem (Principle 7). - States should cooperate to strengthen endogenous capacity-building for sustainable development by improving scientific understanding through exchanges of scientific and technological knowlege, and by enhancing the development, adaptation, diffusion and transfer of technologies, including new and innovative technologies (Principle 9). - In order to protect the environment, the precautionary approach shall be widely applied by the States according to their capabilities (Principle 15). - Environmental impact assessment, as a national instrument, shall be undertaken for proposed activities that are likely to have a significant adverse impact on the environment and are subject to a decision of a competent national authority (Principle 17). • Agenda 21 reflects a global consensus and commitment at the highest political level on how to make development socially, economically, and environmentally sustainable. Among other options it includes protecting the atmosphere, an integrated approach to planning for and managing land resources, combatting deforestation, managing fragile ecosystems: combatting desertification and drought and sustainable mountain development, promoting sustainable agriculture and rural development, conservation of biological diversity, managing biotechnology, protecting and managing the oceans, protecting and managing fresh waters, and supporting science for sustainable development. • A non-legally-binding, authoritative Statement of Forest Principles to guide managing, conserving, and sustainably developing all types of forests, which are essential to economic development and maintaining of all forms of life. • The United Nations Framework Convention on Climate Change aim is to stabilize greenhouse gases in the atmosphere at concentrations that will not dangerously upset the global climate system. • The Convention on Biological Diversity was signed by more than 150 governments at the Rio "Earth Summit" in 1992. It became effective on 29 December 1993 and has become the centre-piece of international efforts to conserve the planet's biological diversity, ensure the sustainable use of its components, and promote the fair and equitable sharing of the benefits arising from use of genetic resources. 3 The Ministerial Conference

  • Fact Sheet on Health and Biodiversity
    Living in harmony with nature Health and Biodiversity We rely on biodiversity to stay healthy. Biodiversity sustains our food supply, is a source of medicines, and supports the provision of clean air and fresh water while also contributing to economic development, cultural and spiritual enrichment. It is now also widely recognized that biodiversity is affected by climate change, with negative consequences for human well-being, but biodiversity, through the ecosystem services it supports, also makes an important contribution to both climate change mitigation and adaptation. As all people require freedom from illness as well as social, emotional, physical, spiritual and cultural well-being, we cannot have healthy societies without biodiversity. Changes to biodiversity can have severe and unpredictable effects on the health of all living things, including people. Clearing new land, for example, can bring people into closer contact with wildlife that may transmit their diseases to humans and also promote the spread of disease from humans to animals. It may also reduce populations of predators that hold disease-carrying organisms in check. In addition, clearing of land may bring about the loss of plants and other organisms useful in medical research or that may contain substances used as medicines. People in developing countries face particularly heavy health burdens from a loss of biodiversity, with impacts on food supply and quality, medicines, and cultural and religious values. It has been estimated that approximately 80% of the world’s population from developing countries rely mainly on traditional medicines derived from plants and that 25% of prescriptions dispensed in United States pharmacies contained plant extracts or active ingredients derived from plants.

    Multiple Stable States and Regime Shifts - Environmental Science - Oxford Bibliographies 3/30/18, 10:15 AM Multiple Stable States and Regime Shifts James Heffernan, Xiaoli Dong, Anna Braswell LAST MODIFIED: 28 MARCH 2018 DOI: 10.1093/OBO/9780199363445-0095 Introduction Why do ecological systems (populations, communities, and ecosystems) change suddenly in response to seemingly gradual environmental change, or fail to recover from large disturbances? Why do ecological systems in seemingly similar settings exhibit markedly different ecological structure and patterns of change over time? The theory of multiple stable states in ecological systems provides one potential explanation for such observations. In ecological systems with multiple stable states (or equilibria), two or more configurations of an ecosystem are self-maintaining under a given set of conditions because of feedbacks among biota or between biota and the physical and chemical environment. The resulting multiple different states may occur as different types or compositions of vegetation or animal communities; as different densities, biomass, and spatial arrangement; and as distinct abiotic environments created by the distinct ecological communities. Alternative states are maintained by the combined effects of positive (or amplifying) feedbacks and negative (or stabilizing feedbacks). While stabilizing feedbacks reinforce each state, positive feedbacks are what allow two or more states to be stable. Thresholds between states arise from the interaction of these positive and negative feedbacks, and define the basins of attraction of the alternative states. These feedbacks and thresholds may operate over whole ecosystems or give rise to self-organized spatial structure. The combined effect of these feedbacks is also what gives rise to ecological resilience, which is the capacity of ecological systems to absorb environmental perturbations while maintaining their basic structure and function.

  • Ecosystem Health Demystified: an Ecological Concept Determined By
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Lincoln University Research Archive Ecosystem health demystified © An ecological concept determined by economic means By E. J. S. Hearnshaw1, R. Cullen1 and K. F. D. Hughey2 1Commerce Division, Lincoln University, 2Environment, Society and Design Division, Lincoln University Abstract This paper addresses “ecosystem health”, a concept recently popularised as the way forward in evaluating nature. The concept is often defined in vague expressions and is being seen more as a broad societal aspiration rather than a specific performance measure of ecosystem management. As such, the paper aims to demystify ecosystem health, that is, to demarcate an accurate and feasible characterisation of the concept. To achieve this aim an examination of the various viewpoints of nature is undertaken. Models of ecosystem health, such as the notions of naturalness, genetic fitness, climax, diversity, stability and keystone species are each considered and subsequently deemed inappropriate, especially when viewing ecosystems as “complex self-organising systems”. Complex self-organising systems are non-linear dynamic systems that have multiple steady states and have emergent and chaotic properties. One model that captures this self- organisation process is Holling’s adaptive cycle. However, when investigating this model it was concluded that there is no means to determining which phase within a system state, or state within a system is ecologically “better”. Therefore, ecosystem health cannot be considered in a positive manner established by scientific objectivity. Rather, the concept must be determined in a normative fashion through it is suggested the elicitation of subjective societal values, so to define an optimal management strategy.

  • Ecosystem Management
    Ecosystem management United Nations Environment Programme An overview Human well-being depends on the health of ecosystems. An ecosystem is a dynamic complex of plants, animals, microorganisms and their nonliving environment, of which people are an integral part. The benefits that we derive from nature and rely on every day, from timber and food to water and climate regulation, are all ecosystem services. In 2005, the UN Millennium Ecosystem Assessment Our goals examined a group of 24 ecosystem services and found that 15 were being degraded or used unsustainably.
