  • Natural and social scientists face a great challenge in the coming decades: to understand the role that humans play in ecosystems, particularly urban ecosystems. Cities and urbanizing regions are complex coupled humannatural systems in which people are the dominant agents. As humans transform natural landscapes into highly human-dominated environments, they create a new set of ecological conditions by changing ecosystem processes and dynamics.

  • Urban Ecology is the study of ecosystems that include humans living in cities and urbanizing landscapes. It is an emerging, interdisciplinary field that aims to understand how human and ecological processes can coexist in human-dominated systems and help societies with their efforts to become more sustainable. It has deep roots in many disciplines including sociology, geography, urban planning, landscape architecture, engineering, economics, anthropology, climatology, public health, and ecology.

  • The Current State and Trends assessment presents the findings of the Condition and Trends Working Group of the Millennium Ecosystem Assessment. This volume documents the current condition and recent trends of the world’s ecosystems, the services they provide, and associated human well-being around the year 2000. Its primary goal is to provide decision-makers, ecosystem managers, and other potential users with objective information and analyses of historical trends and dynamics of the interaction between ecosystem change and human well-being.

  • The idea for this book stems from a meeting sponsored by the European Union, organized by N. van Breemen, and held in Doorweerth at the end of 1991. At this meeting a large number of European scientists discussed the different issues related to the accumulation and decomposition of organic matter in terrestrial ecosystems. One of the objectives was to gather scientists from various disciplines (biologists, chemists, ecologists, agriculturalists) to pool their different disciplinary approaches and come up with a common perspective for future research on soil organic matter.

  • Urban ecology in Berlin has been developing over the past 350 years, from garden floras and wild floras of castles and ruins to the Graduate Research Training Group 780 “Perspectives in Urban Ecology”. This program has brought together universities and scientific institutes from all over Berlin. Since the beginning, urban ecology in Berlin has included approaches from biology and geography, leading to the current interdisciplinary work documented in this summarizing publication.

  • The MA, which focused on ecosystem change and the impacts of such change on human well-being, included a set of sub-global assessments at multiple spatial scales, in addition to the global assessment. This was one of the innovations of the MA compared to other international assessments, which usually focus on global or regional scales alone. The global and sub-global assessments analyzed ecosystem services and human wellbeing from different perspectives and with different stakeholders involved.

  • The focus of the MA is on ecosystem services (the benefits people obtain from ecosystems), how changes in ecosystem services have affected human well-being in the past, and what role these changes could play in the present as well as in the future. The MA is an assessment of responses that are available to improve ecosystem management and can thereby contribute to the various constituents of human well-being. The specific issues addressed have been defined through consultation with the MA users.

  • In the course of researching and writing this book, I have been blessed with abundant help. Arthur McEvoy has been a personal and scholarly model for more than a decade, and it is to him that I owe the greatest thanks for anything that is creative in this project. Whenever recommending one of his favorite books or his foolproof model for writing, he often promised me, “This will change your life.” My studies with him did.

  • The Millennium Ecosystem Assessment was called for by United Nations Secretary-General Kofi Annan in 2000 in his report to the UN General Assembly, We the Peoples: The Role of the United Nations in the 21st Century. Governments subsequently supported the establishment of the assessment through decisions taken by three international conventions, and the MA was initiated in 2001.

  • Urban agglomerations and their resource uses are becoming the dominant feature of the human presence on earth, profoundly changing humanity’s relationship to its host planet and its ecosystems. The cities of the 21 century are where human destiny will be played out and where the future of the biosphere will be determined.

  • Current efforts to address climate change focus mainly on reducing emissions of greenhouse gases, mainly through cleaner energy strategies, and on attempting to reduce vulnerability of communities at risk by improving infrastructure to meet new energy and water needs. This report attempts to set out a compelling argument for including ecosystem‐based approaches to mitigation and adaptation as a third and essential pillar in national strategies to address climate change. The report is targeted at both Bank task teams and country clients.

  • The ecosystem accounting framework presented here is being tested in the context of an open Europe taking stock of its relations to the rest of the world. Because ecosystem accounts are deep-rooted into monitoring databases, implementation presently focuses on physical accounts. Monetary valuations, the adjustment of national accounts aggregates for income and final consumption, and the calculation of ecological debts, are foreseen in subsequent steps within the same logical framework.

  • Ecosystem accounts are being developed as part of the System of Environmental-Economic Accounts which aims at supplementing the UN System of National Accounts with information on the environment and natural capital. The purpose is to broaden the scope of the variables taken into account in policymaking in order to improve understanding of the interdependence and interactions between the economy and the environment.

  • Sustainability of ecosystem needs water which is a finite and vulnerable resource. Fortunately, water is a renewable resource. But management of water resources is always a challenge for sustainability development. Rapid urbanization and industrialization has put more stress on water resources from increased water needs for agriculture, municipal water supply, navigation, recreation, industrial processes and ecosystem maintenance. Agriculture consumes about 70 % of world’s freshwater.

  • Humanity relies on ecosystem products and services including resources, waste absorptive capacity, and space to host urban infrastructure. Environmental changes such as deforestation, collapsing fisheries, and CO2 accumulation in the atmosphere indicate that human demand may well have exceeded the regenerative and absorptive capacity of the biosphere.

  • Of late, the coastal ecosystems are highly degraded due to high population and industrial growth (Glasby & Roonwal, 1995; UNEP, 1997). Due to various pollutions including pesticide poisoning (Sen Gupta et al., 1990), over exploitation of water resources by power plant industries and the municipal uses and encroachment for urban developments force the fishing community to the brink of disappearance. When those natural resources are imperilled, so too are the livelihoods of the many people who live and work there.

  • The new technology could provide solutions to some of our most intractable social problems—the high cost of traffic crashes and transportation infrastructure, the millions of hours wasted in traffic jams, and the wasted urban space given over to parking lots, just to name a few. But if self-driving vehicles become a reality, the implications would also be profoundly disruptive for almost every stakeholder in the automotive ecosystem. As one industry executive put it, “Everything, from how we move goods to how we move ourselves around, is ripe for change.

  • The EPA’s ecosystem protection programs encompass a wide range of approaches that address specific at-risk regional areas and larger categories of threatened systems, such as urban waters, estuaries, and wetlands. Locally generated pollution, combined with pollution carried by rivers and streams and through air deposition, can accumulate in these ecosystems and degrade them over time. The EPA and its federal partners along with states, tribes, municipalities, and private parties, will continue efforts to restore the integrity of the imperiled waters of the United States.
