TL;DR: A review of river restoration can be found in this article, where the authors critically examine how contemporary practitioners approach river restoration and challenges for implementing restoration, which include clearly identified objectives, holistic understanding of rivers as ecosystems, and the role of restoration as a social process.
Abstract: River restoration is one of the most prominent areas of applied water-resources science. From an initial focus on enhancing fish habitat or river appearance, primarily through structural modification of channel form, restoration has expanded to incorporate a wide variety of management activities designed to enhance river process and form. Restoration is conducted on headwater streams, large lowland rivers, and entire river networks in urban, agricultural, and less intensively human-altered environments. We critically examine how contemporary practitioners approach river restoration and challenges for implementing restoration, which include clearly identified objectives, holistic understanding of rivers as ecosystems, and the role of restoration as a social process. We also examine challenges for scientific understanding in river restoration. These include: how physical complexity supports biogeochemical function, stream metabolism, and stream ecosystem productivity; characterizing response curves of different river components; understanding sediment dynamics; and increasing appreciation of the importance of incorporating climate change considerations and resiliency into restoration planning. Finally, we examine changes in river restoration within the past decade, such as increasing use of stream mitigation banking; development of new tools and technologies; different types of process-based restoration; growing recognition of the importance of biological-physical feedbacks in rivers; increasing expectations of water quality improvements from restoration; and more effective communication between practitioners and river scientists.
TL;DR: In this article, the authors examine the effectiveness of restoration as an approach for offsetting biodiversity loss, and conclude that many of the expectations set by current offset policy for ecological restoration remain unsupported by evidence.
TL;DR: In this article, the authors argue that the wetland mitigation banking industry serves as a bellwether that presages problems that other strategies of neoliberal environmental governance will experience, arguing that relying on ecological science to define the unit of trade, and the problem of aligning the somewhat independent relations of law, politics, markets and ecosystems across an array of spatial scales.
TL;DR: A review of market-based instruments (MBIs) in the field of biodiversity conservation and provision of ecosystem services can be found in this article, where six generic categories: regulatory price signals, Coasean type agreements, reverse auctions, tradable permits, direct markets, and voluntary price signals.
TL;DR: The Nature and the Marketplace as mentioned in this paper presents an accessible introduction to the concept of ecosystem services to the economics of the environment and offers a straightforward business economic analysis of conservation issues, eschewing romantic notions about ecosystem preservation in favour of real-world economic solutions.
Abstract: In recent years, scientists have begun to focus on the idea that healthy, functioning ecosystems provide essential services to human populations, ranging from water purification to food and medicine to climate regulation. Lacking a healthy environment, these services would have to be provided through mechanical means, at a tremendous economic and social cost. "Nature and the Marketplace" examines the controversial proposition that markets should be designed to capture the value of those services. Written by an economist with a background in business, it evaluates the real prospects for several of nature's marketable services to "turn profits" at levels that exceed the profits expected from alternative, ecologically destructive, business activities. The author: describes the infrastructure that natural systems provide, how we depend on it, and how we are affecting it; explains the market mechanism and how it can lead to more efficient resource use; looks at key economic activities - such as ecotourism, bioprospecting and carbon sequestration - where market forces can provide incentives for conservation; examines policy options other than the market, such as pollution credits and mitigation banking; and considers the issue of sustainability and equity between generations. "Nature and the Marketplace" presents an accessible introduction to the concept of ecosystem services to the economics of the environment. It offers a clear assessment of how market approaches can be used to protect the environment, and illustrates that with a number of cases in which the value of ecosystems has actually been captured by markets. The book offers a straightforward business economic analysis of conservation issues, eschewing romantic notions about ecosystem preservation in favour of real-world economic solutions. It should be an eye-opening work for professionals, students and scholars in conservation biology, ecology, environmental economics, environmental policy and related fields.
