Book Description
The Everglades ecosystem is vast, stretching more than 200 miles from Orlando to Florida Bay, and Everglades National Park is but a part located at the southern end. During the 19th and 20th centuries, the historical Everglades has been reduced to half of its original size, and what remains is not the pristine ecosystem many image it to be, but one that has been highly engineered and otherwise heavily influenced, and is intensely managed by humans. Rather than slowly flowing southward in a broad river of grass, water moves through a maze of canals, levees, pump stations, and hydraulic control structures, and a substantial fraction is diverted from the natural system to meet water supply and flood control needs. The water that remains is polluted by phosphorus and other contaminants originating from agriculture and other human activities. Many components of the natural system are highly degraded and continue to degrade. Progress Toward Restoring the Everglades is the sixth biennial review of progress made in meeting the goals of the Comprehensive Everglades Restoration Plan (CERP). This complex, multibillion-dollar project to protect and restore the remaining Everglades has a 30-40 year timeline. This report assesses progress made in the various separate project components and discusses specific scientific and engineering issues that may impact further progress. According to Progress Toward Restoring the Everglades, a dedicated source of funding could provide ongoing long-term system-wide monitoring and assessment that is critical to meeting restoration objectives. This report examines the implications of knowledge gained and changes in widely accepted scientific understanding regarding pre-drainage hydrology, climate change, and the feasibility of water storage since the CERP was developed.

Book Description
On a gray and drizzly day in 1983, writer Alice D’Alessio and her math professor husband, Laird, made their way down a curving, tree-lined driveway on their way to a picnic. They were visiting 110 acres of land in Wisconsin’s unglaciated Driftless Area that Laird had inherited from his parents. Emerging from the trees, Alice had her first glimpse of the valley that would become a twenty-five-year labor of love for the couple. In Tending the Valley, Alice chronicles their efforts to return the land to its natural prairie state and to manage their oak and pine woods. Along the way they joined the land restoration movement, became involved in a number of stewardship groups, and discovered the depths of dedication and toil required to bring their dream to fruition. With hard-earned experience and the evocative language of a poet, D’Alessio shares her personal triumphs and setbacks as a prairie steward, along with a profound love for the land and respect for the natural history of the Driftless.

Book Description
This book is the second biennial evaluation of progress being made in the Comprehensive Everglades Restoration Plan (CERP), a multibillion-dollar effort to restore historical water flows to the Everglades and return the ecosystem closer to its natural state. Launched in 2000 by the U.S. Army Corps of Engineers and the South Florida Water Management District, CERP is a multiorganization planning process that includes approximately 50 major projects to be completed over the next several decades. Progress Toward Restoring the Everglades: The Second Biennial Review 2008 concludes that budgeting, planning, and procedural matters are hindering a federal and state effort to restore the Florida Everglades ecosystem, which is making only scant progress toward achieving its goals. Good science has been developed to support restoration efforts, but future progress is likely to be limited by the availability of funding and current authorization mechanisms. Despite the accomplishments that lay the foundation for CERP construction, no CERP projects have been completed to date. To begin reversing decades of decline, managers should address complex planning issues and move forward with projects that have the most potential to restore the natural ecosystem.

Book Description
Twelve years into the Comprehensive Everglades Restoration Project, little progress has been made in restoring the core of the remaining Everglades ecosystem; instead, most project construction so far has occurred along its periphery. To reverse ongoing ecosystem declines, it will be necessary to expedite restoration projects that target the central Everglades, and to improve both the quality and quantity of the water in the ecosystem. The new Central Everglades Planning Project offers an innovative approach to this challenge, although additional analyses are needed at the interface of water quality and water quantity to maximize restoration benefits within existing legal constraints. Progress Toward Restoring the Everglades: The Fourth Biennial Review, 2012 explains the innovative approach to expedite restoration progress and additional rigorous analyses at the interface of water quality and quantity will be essential to maximize restoration benefits.

Book Description
Offers a comprehensive introduction to the issues of control of power systems during cascading outages and restoration process Power System Control Under Cascading Failures offers comprehensive coverage of three major topics related to prevention of cascading power outages in a power transmission grid: modelling and analysis, system separation and power system restoration. The book examines modelling and analysis of cascading failures for reliable and efficient simulation and better understanding of important mechanisms, root causes and propagation patterns of failures and power outages. Second, it covers controlled system separation to mitigate cascading failures addressing key questions such as where, when and how to separate. Third, the text explores optimal system restoration from cascading power outages and blackouts by well-designed milestones, optimised procedures and emerging techniques. The authors — noted experts in the field — include state-of-the-art methods that are illustrated in detail as well as practical examples that show how to use them to address realistic problems and improve current practices. This important resource: Contains comprehensive coverage of a focused area of cascading power system outages, addressing modelling and analysis, system separation and power system restoration Offers a description of theoretical models to analyse outages, methods to identify control actions to prevent propagation of outages and restore the system Suggests state-of-the-art methods that are illustrated in detail with hands-on examples that address realistic problems to help improve current practices Includes companion website with samples, codes and examples to support the text Written for postgraduate students, researchers, specialists, planners and operation engineers from industry, Power System Control Under Cascading Failures contains a review of a focused area of cascading power system outages, addresses modelling and analysis, system separation, and power system restoration.

Book Description
The pace, intensity, and scale at which humans have altered our planet in recent decades is unprecedented. We have dramatically transformed landscapes and waterways through agriculture, logging, mining, and fire suppression, with drastic impacts on public health and human well-being. What can we do to counteract and even reverse the worst of these effects? Restore damaged ecosystems. The Primer of Ecological Restoration is a succinct introduction to the theory and practice of ecological restoration as a strategy to conserve biodiversity and ecosystems. In twelve brief chapters, the book introduces readers to the basics of restoration project planning, monitoring, and adaptive management. It explains abiotic factors such as landforms, soil, and hydrology that are the building blocks to successfully recovering microorganism, plant, and animal communities. Additional chapters cover topics such as invasive species and legal and financial considerations. Each chapter concludes with recommended reading and reference lists, and the book can be paired with online resources for teaching. Perfect for introductory classes in ecological restoration or for practitioners seeking constructive guidance for real-world projects, Primer of Ecological Restoration offers accessible, practical information on recent trends in the field.
