The Great Experiment in Conservation

2025/08/12 出版

The Adirondack region of New York State is, in many respects, America's cauldron of conservation. It was there, more than a century ago, that wanton exploitation of forests first aroused concern about human impact on the environment. It was there that Americans first began to set aside lands proclaimed as "forever wild." The establishment of the Adirondack Park created an immense landscape of 6 million acres composed of a mixture of public and private lands in nearly equal proportion. This unprecedented blend of human communities within wild lands makes the Adirondack Park perhaps one of the greatest case studies in conservation and development in U.S. history. Representing a remarkable achievement in environmental scholarship and drawn from decades of research, The Great Experiment in Conservation captures the wisdom born of the last thirty years of the park's evolution. The editors bring together leading scholars, activists, and practitioners--those who know the Park's origin and the realities of living in a protected area--to narrate this history. Organized into three sections, contributors explore the ecological, cultural, and economic aspects of the region, drawing lessons from successes and failures as they struggle to find the right balance of private interests and public controls. With keen insight and deep passion, the authors reveal the Adirondack Park's rich natural and cultural history in shaping conservation policy, providing vital contributions to the future study of land preservation. Contributors include: Herman Daly, Bill McKibben, Barbara McMartin, Philip G. Terrie, Amy Vedder, and Bill Weber.

Lake Erie's Long Point and the Company that saved it

Petra Books 出版
2025/08/11 出版

Long Point, a wilderness in the Canadian waters of Lake Erie, attracts thousands of migrating waterfowl. In the 1800s it was becoming a home for nefarious activities including illegal logging and hunting, drunkenness and prostitution. Seeking to bring the lawlessness under control, the pre-confederation British Government parcelled off the land for auction in 1866 and a group of wealthy businessmen seeking a private duck hunting preserve established the Long Point Company. With the arrival of the Gilded Age in the 1870s, American millionaires came to dominate the membership. The area is designated a UNESCO Biosphere Reserve. www.unesco.org/en/mab/long-pointPutting his curiosity and research skills to use, Stephen Selk has documented the symbiotic relationship that has proven beneficial to both Long Point and the shareholders.

Remediation Strategies for Soil and Water

Mdpi AG 出版
2025/08/11 出版

With the rapid development of industries worldwide, soil and water pollution have accelerated in recent decades. The pollutants, including heavy metals, polycyclic aromatic hydrocarbons, antibiotics, and microplastics, in soil and water pose severe environmental problems, presenting serious risks to human health and the ecological system. Approximately 4 billion people, representing around half of the world's population, experience severe physical water scarcity for at least part of the year. Hence, several techniques have been developed for the remediation of contaminated soil and water, including adsorption, membrane separation, advanced oxidation, ion exchange, electrochemical treatment, microbial degradation, and phytoremediation. Considering the ongoing issue of pollution and emerging pollutants, remediation strategies for soil and water should be further optimized to focus on developing functional materials, improving remediation efficiency, and enhancing integrated remediation processes. This Reprint, entitled "Remediation Strategies for Soil and Water," features six research articles and three review papers, each addressing critical aspects of remediation processes for soil and water.

Tree Day

Meg,Lowman  著
University 出版
2025/08/09 出版

An hourly guide that spotlights twenty-four trees as they root, flower, and host diverse forest life. In this short book, treetop explorer Meg Lowman guides us through a global forest. Each chapter of Tree Day introduces a single tree during a single hour, highlighting twenty-four species from around the world. In the dark of Yemen's night, it is too early to see the red sap from which the dragon's blood tree gets its name. But if we watch closely, we will see nocturnal geckos carry the trees' pollen in their snouts. Later, in the Pacific Northwest, we climb the world's tallest species, the coastal redwood. The morning fog is a reminder that redwoods absorb water through their roots and canopies, helping them survive such heights. The sun is already low in the sky on an autumn afternoon. Given the darkness of this New England forest, the sugar maple's leaves have stopped producing chlorophyll that converts light into energy--and green gives way to vivid crimson foliage. After many hours of boiling, the maple sap makes delicious maple syrup. As the sun sets in Mexico, we observe the origin of another treat, chocolate. The cocoa tree's flowers sprout along its trunk and branches, allowing easy access for tiny insects like midges that pollinate the tree and start the process of making delicious food for humans, monkeys, bats, and squirrels. By the end of our tree day, we will understand that trees are the silent caretakers of our planet, providing us with medicines, foods, machinery for making fresh water and oxygen, and more. For each hour, celebrated artist Thibaud H矇rem has depicted these trees with gorgeous pen and ink illustrations. Working together to narrate and illustrate these unique moments in time, Lowman and H矇rem have created an engaging read that is a perfect way to spend an hour or two--and a true gift for anyone who has ever looked up at a tree in wonder.

An Analysis of the Effectiveness of Pollution Prevention in Reducing Environmental Compliance Costs

Biblioscholar 出版
2025/08/08 出版

The objective of the Air Force's compliance through pollution prevention (CTP2) program is to reduce overall environmental compliance (EC) cost and risk (compliance burden) associated with maintaining compliance at an installation through increased pollution prevention (P2) efforts. However, no quantifiable evidence has been produced that suggests P2 projects are actually reducing compliance burden. Therefore, this research attempts to determine if projects categorized as P2 truly reduce compliance burden.This research demonstrated that, under the current burden calculation methodology, the compliance site inventory data should not be used to measure or track compliance burden reductions.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Verification and Comparison of Polar MM5 and AFWA MM5 Forecasts Over Alaska

Biblioscholar 出版
2025/08/08 出版

The Mesoscale Model 5th Generation (MM5) is used for operational support to Air Force missions in the Alaskan Theater. The 11th Operational Weather squadron has identified problems with the MM5 producing excessively warm surface temperature forecasts. The Polar MM5 (PMM5), developed by the Byrd Polar Research Center for the high latitude ice sheets of Antarctica and Greenland, is tested over the Alaskan domains used by the Air Force Weather Agency to determine the utility in replacing the MM5 with the PMM5. The verification of surface temperature, pressure and wind as well as upper-air temperature, geopotential height, and relative humidity of 27-hour PMM5 forecasts are compared to the MM5 forecasts to assess the differences between the models' accuracies. A grid-to-station inverse-weighted linear interpolation technique is used to compare model output to surface observation for 71 locations and to radiosonde upper-air observations for 7 locations. The results are based on 67 forecasts made over a 4-month period during the Fall-Winter of 2001.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Here Comes the Sun

W. W. Norton 出版
2025/08/08 出版

Our climate, and our democracy, are melting down. But Bill McKibben, one of the first to sound the alarm about the climate crisis, insists the moment is also full of possibility. Energy from the sun and wind is suddenly the cheapest power on the planet and growing faster than any energy source in history--if we can keep accelerating the pace, we have a chance. Here Comes the Sun tells the story of the sudden spike in power from the sun and wind--and the desperate fight of the fossil fuel industry and their politicians to hold this new power at bay. From the everyday citizens who installed solar panels equal to a third of Pakistan's electric grid in a year to the world's sixth-largest economy--California--nearly halving its use of natural gas in the last two years, Bill McKibben traces the arrival of plentiful, inexpensive solar energy. And he shows how solar power is more than just a path out of the climate crisis: it is a chance to reorder the world on saner and more humane grounds. You can't hoard solar energy or hold it in reserves--it's available to all.There's no guarantee we can make this change in time, but there is a hope--in McKibben's eyes, our best hope for a new civilization: one that looks up to the sun, every day, as the star that fuels our world.

Territorial Space and Transportation Coordinated Development

Gaoru,Zhu  著
Mdpi AG 出版
2025/08/07 出版

Territorial space and transportation are closely related to each other. The interaction mechanism and coordinated development of the two are important research directions of academic concern. On the one hand, transportation networks are the skeleton of national and regional development, and the comprehensive transportation system provided by highways, railways, aviation, and water promotes the development of territorial space. On the other hand, the pressure of transportation infrastructure and transportation activities on the protection of territorial space such as ecological and agricultural land is also increasing. The question of how to coordinate the relationship between development and protection, use the network effect of transportation to empower regional development, and improve the environmental impact of the transportation field, thereby enhancing regional sustainability, is a key scientific issue that needs to be studied urgently. In order to promote research in the field of territorial space and transportation coordination, as well as the deep integration of production, study, and research, we have organized a Special Issue titled "Coordinated development of territorial space and transportation" in Land. This reprint publication includes 16 articles, encompassing a wide range of critical topics, such as comprehensive transportation network planning, the impact of transportation on land use, the impact of land use on transportation, the interaction between transportation networks and territorial space, and territorial space development guided by transportation.

Science in Resistance

2025/08/06 出版

Scientists around the world rise up for climate and ecological justice In April 2022, hundreds of scientists rose in civil disobedience, breaking the law in more than twenty-eight countries. Risking arrest, they glued their hands to roads, blocked government and corporate buildings, and chained themselves to the White House fence. In Science in Resistance, Fernando Racimo provides a first-person account of the Scientist Rebellion, a growing international movement of researchers stepping beyond conventional roles to alert the public about the need for action in the climate emergency. Combining personal stories, interviews with frontline activists, and insights from research on direct action and academia, he explores the challenges scientists face when taking a stand for climate and social justice. Reflecting on his role as a scientist-activist, Racimo describes how he came to be involved in the movement. He also explores the many ways in which academic institutions today are complicit in climate breakdown--whether by accepting funding from and collaborating with the very industries driving it, or by discouraging scientists from speaking up. Drawing on lessons from political science, psychology, ecology, sociology, and the history of science, he explains how academia can be transformed to become an actor for good in the emergency.

Urban Regeneration

Mdpi AG 出版
2025/08/06 出版

Many aspects come into play when addressing urban regeneration issues, and various interventions are needed to ensure cities are resilient and prepared to respond to environmental, economic, and social challenges. Resilience is understood as a "cross-cutting condition" in the reorganisation of a city, as the ability to provide adaptive and timely responses to numerous challenges and adverse events. Land consumption, characterised by the expansion of artificial cover for residential, manufacturing, and infrastructure purposes, is a worrying trend globally. There is a need to monitor and formulate strategies to mitigate land consumption and safeguard ecosystem services. Only through joint actions will cities be prepared to address key land vulnerabilities exacerbated by climate change: drought and water scarcity, heat waves in urban areas, unconventional events, and hydrogeological risk. This Special Issue aims to identify contextual actions that can reduce land consumption, promote de-impermeabilization, and encourage re-naturalisation, focusing on enhancing ecosystem services in land use activities. Therefore, it focuses on understanding the contributions of ecosystem services, landscape restoration and green infrastructure for climate mitigation, and land use reduction in urban regeneration processes.

Urban Planning and Housing Market

Mdpi AG 出版
2025/08/04 出版

The interaction between urban planning and the housing market plays a key role in the context of progressing urbanization, urban population growth, and the rising demand for housing. The rational distribution of housing resources in cities (and functional urban areas) is one of the crucial priorities of urban planning. The relevant measures should align with the principles of sustainable development, as well as the rational management of space and social justice. Existing problems and social needs should be identified and resolved in order to improve the quality of life. The identification and evaluation of processes in the housing market-across the economic, social, and spatial dimensions-are essential elements of urban planning. The development of geographic information systems, along with quantitative and qualitative analytical methods, promotes an innovative approach to the evaluation of urban space, where housing resources that meet fundamental human needs play a special role. How can urban planning effectively cater to housing needs? Can urban planning improve housing affordability and housing supply? What remedial measures can be implemented to prevent spatial, social, and economic segregation in cities? How and where should new housing estates be planned? Can urban densification be reconciled with a high quality of life? This Special Issue will focus on the extent to which urban planning and management systems address the complex and dynamic trends in the housing market.

Groundwater Pollution Control and Groundwater Management

Yunhui,Zhang  著
Mdpi AG 出版
2025/08/04 出版

Groundwater, a hidden reservoir beneath the Earth's surface, is a vital lifeline for billions around the world, supporting drinking water supplies and industrial and agricultural production. As a core component of the hydrological cycle, it interacts dynamically with ecosystems, soil, and surface water. The increasing demand for freshwater as a result of population growth and climate change has intensified the need to address groundwater vulnerability. Sources of pollution such as agricultural runoff, industrial wastewater, untreated wastewater, and chemical infiltration threaten water quality by introducing heavy metals, nutrients, and pathogens, endangering human health and ecological balance. These risks have a disproportionate influence on marginalized communities, exacerbating socio-economic disparities. Anthropogenic pressures like urbanization and over-extraction further hinder the sustainability of groundwater and therefore necessitate a comprehensive management framework. Mitigation methods require the adoption of practices to reduce pollution in agriculture and industry and the promotion of public participation in management. Interdisciplinary collaboration among researchers, policymakers, and communities is essential to advance remediation strategies and sustainable governance. This Reprint combines case studies, on-site data, and successful intervention measures to elucidate contamination pathways, evaluate management efficacy, and chart conservation roadmaps. Protecting the integrity of groundwater is crucial for granting fair access to resources and combating escalating challenges to the climate and human life.
