Dopo anni di sfruttamento indiscriminato, il periodo dell'Antropocene ci restituisce una natura le cui reazioni rendono la Terra sempre meno abitabile: invertire la rotta è diventata oggi un'urgenza prioritaria. Il paradigma dei servizi ecosistemici muove un passo nella giusta direzione nel considerare la molteplicità dei benefici offerti al genere umano dall'ambiente, ma si presta a derive quantitative che rischiano di estendere la mercificazione anche al mondo della natura. Questo volume indaga da più orizzonti disciplinari la consistenza e l'utilità per le scienze del territorio del paradigma dei servizi ecosistemici, avanzando la proposta di ricondurlo all'interno dell'approccio bioregionale con l'introduzione del concetto di servizi eco-territoriali.

For the better part of the last century, "preservation" and "multi-use conservation" were the watchwords for managing federal lands and resources. But in the 1990s, amidst notable failures and overwhelming needs, policymakers, land managers, and environmental scholars were calling for a new paradigm: ecosystem management. Such an approach would integrate federal land and resource management across jurisdictional boundaries; it would protect biodiversity and economic development; and it would make federal management more collaborative and less hierarchical. That, at any rate, was the idea. Where the idea came from-why ecosystem management emerged as official policy in the 1990s-is half of the story that James Skillen tells in this timely book. The other half: Why, over the course of a mere decade, the policy fell out of favor?This closely focused history describes an old system of preservation and multi-use conservation ill equipped to cope with the new ecological, legal, and political realities confronting federal agencies. Ecosystem management, it was assumed, would not demand choices between substantive and procedural needs. Looming even larger in the push for the new approach was a shift of emphasis in both ecology and political science-from stability and predictability to dynamism and contingency. Ecosystem management offered more modest managerial goals informed by direct public participation as well as scientific expertise. But as Skillen shows, this purported balance proved to be the policy's undoing. Different interpretations presented conflicting emphases on scientific and democratic authority. By 2001, when both models had been tested, the Bush administration faulted federal ecosystem management for running "willy-nilly all over the west," and shelved the policy.In this book, Skillen gets at the truth behind these contrary interpretations and claims to clarify how federal ecosystem management worked-and didn't-and how many of the principles it embodied continue to influence federal land and resource management in the twenty-first century. How the policy's lessons apply to our politically and environmentally fraught moment is, finally, considerably clearer with this informed and thoughtful book in hand.

Understanding Soils of Mountainous Landscapes: Sustainable Use of Soil Ecosystem Services and Management focuses on the patterns and processes of mountainous soils, including threats due to the fragile nature of mountain ecosystems, and the conservation and management of soil ecosystem services and restoration processes. The book covers a balanced approach to land and resource management, ensuring that environmentally and socio-culturally sound interventions are developed and applied in the complex geophysical, ecological, and social landscapes of the world's mountain systems. The book provides holistic understanding of mountain soils to help environmental and soil scientists gain insight and develop new problem-solving approaches. With obvious up- and downstream linkages (e.g., a large proportion of urban canters globally depend on water that originates in the mountains) as well as globalization (e.g., continental-scale impacts of air pollution and climate change on glaciers), the long-range success of conservation measures in mountain regions requires that the following discrete but interconnected interventions be pursued concurrently: (1) the protection of biodiversity and ecosystem services, (2) empowerment of mountain communities (including family farming), and (3) elaboration of more thoughtful, context-specific policy environments for sustainable mountain development.

The world's ecosystems are at increasing risk of rapid degradation and collapse, as documented in recently published accounts by the United Nations Environment Programme. Many societies are either unaware of the key value that diversity of animals, plants and other life-forms play in the role of healthy and functioning ecosystems and sustained human livelihoods, or are failing to develop policies and strategies for their protection. The challenges we face today are to recognize and anticipate change in ecosystem services in all of its forms and to appreciate human and societal dynamic impacts. To solve these challenging opportunities that mask themselves as insoluble problems, a gathering of renowned scientists from Africa, Europe, India, North America, the Middle East, North Africa and the Russian Federation, under the sponsorship of the NATO Science for Peace and Security Program, EPA Ecosystem Services Research Program, the United Nations Environment Programme, the Desert Research Institute and the Pell Center for International Relations and Public Policy, provides an extended exchange of views and experience. Collectively, they focused on ecosystem services in relation to human welfare, peace and security. This volume represents an extraordinary collective effort to define, design and deliver ecosystem services for the benefit of humanity. Achieving Environmental Security: Ecosystem Services and Human Welfare reflects NATO's "third dimension," which goes beyond cooperation in political and defense fields to encourage cooperation related to civil emergency planning and scientific and environmental cooperation and to focus on stability, sustainability and solidarity among peoples, states and regions, to understand, appreciate and incorporate ecosystem services into the way we live our lives.
