Confronting the Climate Challenge: U.S. Policy Options
by Lawrence Goulder Marc HafsteadWithout significant reductions of greenhouse gas emissions, climate change will cause substantial damage to the environment and the economy. The scope of the threat demands a close look at the policies capable of reducing the harm. Confronting the Climate Challenge presents a unique framework for evaluating the impacts of a range of U.S. climate-policy options, both for the economy overall and for particular household groups, industries, and regions. Lawrence Goulder and Marc Hafstead focus on four alternative approaches for reducing carbon dioxide emissions: a revenue-neutral carbon tax, a cap-and-trade program, a clean energy standard, and an increase in the federal gasoline tax. They demonstrate that these policies—if designed correctly—not only can achieve emissions reductions at low cost but also can avoid placing undesirable burdens on low-income household groups or especially vulnerable industries.Goulder and Hafstead apply a multiperiod, economy-wide general equilibrium model that is distinct in its attention to investment dynamics and to interactions between climate policy and the tax system. Exploiting the unique features of the model, they contrast the shorter- and longer-term policy impacts and focus on alternative ways of feeding back—or “recycling”—policy-generated revenues to the private sector. Their work shows how careful policy design, including the judicious use of policy-generated revenues, can achieve desired reductions in carbon dioxide emissions at low cost, avoid uneven impacts across household income groups, and prevent losses of profit in the most vulnerable U.S. industries. The urgency of the climate problem demands comprehensive action, and Confronting the Climate Challenge offers important insights that can help elevate policy discussions and spur needed efforts on the climate front.
Confronting the Climate: British Airs and the Making of Environmental Medicine
by Vladimir JankovićThis book explores the social origins of the Western preoccupation with health and environmental hazards. It looks at the rise of the dichotomy between the vulnerable 'in' and the threatening 'out' by examining the pathologies associated with weather, domestic space, ventilation, clothing, and travel in Britain at the turn of the 19th century.
Confronting the Nation's Water Problems: The Role of Research
by Committee on Assessment of Water Resources ResearchIn order to confront the increasingly severe water problems faced by all parts of the country, the United States needs to make a new commitment to research on water resources. A new mechanism is needed to coordinate water research currently fragmented among nearly 20 federal agencies. Given the competition for water among farmers, communities, aquatic ecosystems and other users-as well as emerging challenges such as climate change and the threat of waterborne diseases-Confronting the Nation's Water Problems concludes that an additional $70 million in federal funding should go annually to water research. Funding should go specifically to the areas of water demand and use, water supply augmentation, and other institutional research topics. The book notes that overall federal funding for water research has been stagnant in real terms for the past 30 years and that the portion dedicated to research on water use and social science topics has declined considerably.

Connected Lands: New Perspectives on Ecological Networks Planning (UNIPA Springer Series)
by Filippo Schilleci Vincenzo Todaro Francesca LottaThis book explores and outlines the reference theoretical basis of ecological networks within the international debate, focusing on how protected areas should no longer be considered as the sum of different components but rather as a network. The various European, transnational and national models of ecological networks/connections are analyzed on the basis of a detailed, updated study of relevant documents. The complex picture that emerges shows a wide range of reticular-ecological models within European plans and programs, but also many non-integrated experiences. The book subsequently examines the regulation of ecological networks/connections within planning instruments, explaining the critical points and referring to different ecological network models and specific local realities. Lastly, the book addresses two Italian case studies regarding the different normative and planning frameworks, both at a national and regional level, and demonstrating not only how ecological networks/connections can be structured within plans, but also how these networks/connections represent the core element of territory development and preservation. As such, it provides an essential tool for containing habitat fragmentation, offering a new perspective that integrates theoretical approaches and methods with planning models and the lessons learned from local applications.

Connecticut River Valley Flood of 1936 (Disaster)
by Joshua ShanleyIn the beginning of the twentieth century, the Connecticut River Valley was a thriving manufacturing hub for fabric, arms and brass. But early in the spring of 1936, nearly two feet of rain created havoc on a massive scale, killing more than one hundred people and leaving tens of thousands homeless, unemployed and without power for weeks. Patrols were conducted in rowboats on city streets. Typhoid and other public health issues complicated recovery efforts. Adjusted for today's standard, damage estimates exceeded $9 billion, and the flood helped launch FDR's Flood Control Act of 1936. Dams, reservoirs and dikes were constructed to control future flooding. Much of that system now remains in place but has gone largely unmaintained. Author Josh Shanley recounts the greatest flood in New England history and examines the potential for future floods.
Connecting Ecologies: Integrating Responses to the Global Challenge (Routledge Studies in Religion and Environment)
by Gavin Flood Patrick RiordanConnecting Ecologies focuses on the environmental aspects of Pope Francis’ encyclical Laudato Si’ and the challenge to care for our common home. It considers how best to devise and implement the new societal models needed to tackle the ecological problems facing the world today. The book addresses the need for and complexity of an integral ecology, one that looks not only at physical and biological processes but also allows for the contributions of theology, philosophy, spirituality, and psychology, including the implications for the human and social sciences. The contributions document four categories of resonances, resources, requirements, and responses evoked by a reading of Laudato Si’ and include consideration of other faith traditions. They reflect on how care for our common home motivates people in different places, cultures, and professions to cooperate for myriad goods in common. The volume is particularly relevant for scholars working in religious studies and theology with an interest in ecology, the environment, and the Anthropocene.
Connecting the Drops: A Citizens' Guide to Protecting Water Resources
by Karen Schneller-McdonaldThe need for improved water resource protection, beginning with grassroots action, is urgent. The water we use depends on networks of wetlands, streams, and watersheds. Land-use activities, however, are changing these natural systems. Often these changes result in ecological damage, flooding, water pollution, and reduced water supply. We need a healthy environment that sustains our personal and community health; we also need vibrant and sustainable economic development that does not destroy the benefits we derive from nature. Our ability to accomplish both depends on how well we can "connect the drops."In this book, Karen Schneller-McDonald presents the basics of water resource protection: ecology and watershed science; techniques for evaluating environmental impacts; obstacles to protection and how to overcome them; and tips for protection strategies that maximize chances for success. Schneller-McDonald makes clear the important connections among natural cycles, watersheds, and ecosystems; the benefits they provide; and how specific development activities affect water quality and supply.The methods described in Connecting the Drops have broad application in diverse geographic locations. The environmental details may differ, but the methods are the same. For water resource managers and concerned citizens alike, Connecting the Drops helps readers interpret scientific information and contextualize news media reports and industry ads--ultimately offering "how to" guidance for developing resource protection strategies.
Connectivity Conservation Management: A Global Guide
by Michael Lockwood Graeme L. Worboys Wendy L. FrancisIn an era of climate change, deforestation and massive habitat loss, we can no longer rely on parks and protected areas as isolated 'islands of wilderness' to conserve and protect vital biodiversity. Increasing connections are being considered and made between protected areas and 'connectivity' thinking has started to expand to the regional and even the continental scale to match the challenges of conserving biodiversity in the face of global environmental change. This groundbreaking book is the first guide to connectivity conservation management at local, regional and continental scales. Written by leading conservation and protected area management specialists under the auspices of the World Commission on Protected Areas of IUCN, the International Union for the Conservation of Nature, this guide brings together a decade and a half of practice and covers all aspects of connectivity planning and management The book establishes a context for managing connectivity conservation and identifies large scale naturally interconnected areas as critical strategic and adaptive responses to climate change. The second section presents 25 rich and varied case studies from six of the eight biogeographic realms of Earth, including the Cape Floristic Region of Africa, the Maloti-Drakensberg Mountains, the Australian Alps to Atherton Corridor, and the Sacred Himalayan Landscape connectivity area (featuring Mount Everest.) The remarkable 3200 kilometre long Yellowstone to Yukon corridor of Canada and the United States of America is described in detail. The third section introduces a model for managing connectivity areas, shaped by input from IUCN workshops held in 2006 and 2008 and additional research. The final chapter identifies broad guidelines that need to be considered in undertaking connectivity conservation management prior to reinforcing the importance and urgency of this work. This handbook is a must have for all professionals in protected area management, conservation, land management and resource management from the field through senior management and policy. It is also an ideal reference for students and academics in geography, protected area management and from across the environmental and natural sciences, social sciences and landuse planning.

Methods of quantification and measurement are described, providing an overview of methodologies and indices that can be used to assess connectivity as a property of soils and landscapes, and approaches for modelling connectivity are reviewed. The book concludes with an examination of applications of connectivity thinking in environmental management. Accessible and self-contained, this text is a key resource for practitioners, researchers and graduate students in geomorphology.
Conscience Incorporated: Pursue Profits While Protecting Human Rights
by Michael H. PosnerA guide for business leaders working to create socially conscious, sustainable companies—while pursuing profitsAmid growing international concerns about income inequality, labor abuses, racial injustice, and disinformation online, Conscience Incorporated examines the gaps in current corporate social responsibility measures and what more needs be done to address these challenges. The rise of new technologies such as smartphones and social media have made it easier than ever to document and spread awareness of corporate actions. Despite these developments, large corporations often fail to meaningfully address the human rights abuses linked to their business models and practices. In Conscience Incorporated, Michael Posner addresses what lies at the root of these challenges, drawing on his extensive personal experience as a human rights lawyer, State Department official under President Obama, chair of the Fair Labor Association and Director of the Center for Business and Human Rights at NYU Stern School of Business.Drawing from research into the history of business ethics and anchoring his argument with examples of companies publicly accused of human rights abuses—Nike, Coca-Cola, Walmart, Meta, and more—Posner provides a blueprint for global business leaders to navigate human rights challenges and adopt sustainable corporate practices. Conscience Incorporated highlights the need for increased protections for outsourced workers in faraway nations, greater attention to harmful online content, and prioritization of human rights by investors. He argues that growing public awareness has not been enough to enforce ethical practices for global businesses. As a result, governments, especially in Europe, are becoming more involved in regulating global business practices in various industries.Posner proposes a series of concrete reforms and argues compellingly for why businesses need to devote greater time and resources to protecting basic human rights. Conscience Incorporated is a powerful challenge to the status quo and advocates for a fundamental shift in the principles that govern global businesses.

Consequentialism and Environmental Ethics: Consequentialism And Environmental Ethics (Routledge Studies in Ethics and Moral Theory)
by Ramona Ilea Avram Hiller Leonard KahnThis volume works to connect issues in environmental ethics with the best work in contemporary normative theory. Environmental issues challenge contemporary ethical theorists to account for topics that traditional ethical theories do not address to any significant extent. This book articulates and evaluates consequentialist responses to that challenge. Contributors provide a thorough and well-rounded analysis of the benefits and limitations of the consequentialist perspective in addressing environmental issues. In particular, the contributors use consequentialist theory to address central questions in environmental ethics, such as questions about what kinds of things have value; about decision-making in light of the long-term, intergenerational nature of environmental issues; and about the role that a state’s being natural should play in ethical deliberation.

The book ends with a discussion of the complex relationshipsamong civil society, governments, and international borders.By considering the history, goals, successes, and failures of two divergentinitiatives, the book offers important insights into the field oftransborder conservation along with valuable lessons for those studyingor working in the field.
Conservation Agriculture and Climate Change: Impacts and Adaptations
by Rites H. Saha Dhananjay Barman Madhusudan Behera Gouranga KarConventional tillage and burning crop residues has degraded the soil resource base and intensified soil degradation with concomitant decrease in crop production capacity. The emerging issue of global warming coupled with greenhouse gases emissions has further aggravated the scenario. Conservation agriculture helps in reducing many negative effects of conventional agriculture such as soil erosion, soil organic matter decline, water loss, soil physical degradation, and fuel use. Conservation Agriculture helps improve biodiversity in the natural and agro-ecosystems. Complemented by other good agricultural practices including the use of quality seeds, integrated pest, nutrient and water management, Conservation Agriculture provides a base for sustainable intensification of the agricultural production system. Moreover, the yield levels in Conservation Agriculture systems are higher than traditional intensive tillage systems with substantially less production costs. This book provides comprehensive understanding of the subject with topics related to climate change mitigation strategies, approaches and impact of conservation agriculture on natural resource management.

This is especially so in Africa where traditional agricultural practices have become unsustainable due to severe exploitation of natural resources with negative impacts on the environment and food system. In addition, agricultural land use in Africa today faces major challenges including increased costs, climate change and a need to transform to more sustainable production intensification systems. Conservation Agriculture has emerged as a major alternative sustainable climate smart agriculture approach in Africa and has spread to many African countries in the past decade as more development and research, including in sustainable mechanization, has enabled its extension and uptake. It is key to transforming Africa's agriculture and food system given its ability to restore soil health, biodiversity and productivity of millions of smallholder farms as well as larger-scale farms. This landmark volume is based on the material presented at the Second Africa Congress on Conservation Agriculture which was held in Johannesburg, South Africa, 9-12 October 2018. The main theme of the Congress was 'Making Climate Smart Agriculture Real in Africa with Conservation Agriculture: Supporting the Malabo Declaration and Agenda 2063'. The Congress was aligned to mobilize stakeholders in all agriculture sectors to provide greater technical, institutional, development and investment support, impetus and direction to the vision and agenda for transforming African agriculture as set out by the Malabo Declaration and Agenda 2063. This book is aimed at all agricultural stakeholders in the public, private and civil sectors in Africa engaged in supporting the transformation of conventional tillage agriculture to Conservation Agriculture. The book will be of interest to: researchers, academics, students, development stakeholders, public and private sector investors and policy makers as well as institutional libraries across the world.
Conservation Agriculture in India: A Paradigm Shift for Sustainable Production (Earthscan Food and Agriculture)
by A. R. SharmaThis book examines the current situation, levels of adoption, management practices, and the future outlook of conservation agriculture in India, and also in other tropical and subtropical regions of the world. While conservation agriculture is proposed as an important means to combat climate change, improve crop productivity and food affordability, and to protect the environment, the adoption of conservation agriculture in India, and south-east Asia more broadly, has been slow. This volume reflects on the current status of conservation agriculture in India, asking why adoption has been slow and putting forward strategies to improve its uptake. The chapters cover the various aspects of crop management such as soil, water, nutrients, weeds, crop residues, machinery, and energy, in a range of environments, including irrigated and rainfed regions. The impact of climate change and the economic considerations behind the adoption of conservation agriculture are also discussed. The volume concludes by discussing the future outlook for conservation agriculture in India, in particular drawing out parallels with other tropical and subtropical regions of the world. This book will be of great interest to students and scholars of conservation agriculture, sustainable agriculture, crop and soil management, and environmental and natural resource management.

Conservation Agriculture: Conservation Agriculture for Sustainable Agriculture
by Ashok K. Patra Ram C. Dalal Somasundaram Jayaraman Suresh K. ChaudhariFeeding the increasing global population, which is projected to reach ~10 billion by 2050, there has been increasing demands for more improved/sustainable agricultural management practices that can be followed by farmers to improve productivity without jeopardizing the environment and ecosystem. Indeed, about 95% of our food directly or indirectly comes from soil. It is a precious resource, and sustainable soil management is a critical socio–economic and environmental issue. Maintaining the environmental sustainability while the world is facing resource degradation, increasing climate change and population explosion is the current challenge of every food production sectors. Thus, there is an urgent need to evolve a holistic approach such as conservation agriculture to sustain higher crop productivity in the country without deteriorating soil health. Conservation Agriculture (CA), is a sustainable approach to manage agro–ecosystems in order to improve productivity, increase farm profitabilty and food security and also enhance the resource base and environment. Worldwide, it has been reported various benefits and prospects in adopting CA technologies in different agro-climatic conditions. Yet, CA in arid and semi-arid regions of India and parts of south Asia raises uncertainities due to its extreme climates, large scale residue burning, soil erosion and other constraints such as low water holding capacity, high potential evapotranspiration, etc . Thus, the proposed book has 30 chapters addressing all issues relevant to conservation agriculture/no-till farming system. The book also gives further strengthening existing knowledge in relation to soil physical, chemical and biological processes and health within close proximity of CA as well as machinery requirements. Moreover, the information on carbon (C) sequestration, C credits, greenhouse gas (GHG) emission, mitigation of climate change effects and socio-economic view on CA under diverse ecologies namely rainfed, irrigated and hill eco-region is also deliberated. For large scale adoption of CA practices in South Asian region especially in India and other countries need dissemination of best-bet CA technologies for dominant soil types/cropping systems through participatory mode, strong linkages and institutional mechanism and public-private-policy support.We hope this book gives a comprehensive and clear picture about conservation agriculture/no-till farming and its associated problem, challenges, prospects and benefits. This book shall be highly useful reference material to researchers, scientists, students, farmers and land managers for efficient and sustainable management of natural resources.
Conservation Aquaculture: An Evolution-based Approach for the Production of Fish for Aquaculture-assisted Fisheries Programs
by Douglas TaveStocking hatchery-produced fish has been a standard component of fisheries management for over 100 years. This book discusses the production of hatchery fish used in aquaculture-assisted fisheries programs to help stabilize and recover endangered species. For the most part, these programs have been unsuccessful, and a reason why is that the traditional approach to fish culture produces fish that are genetically and behaviorally ill-suited to help recover an imperiled species. The hatchery environment and management used to culture the fish makes them sub-viable in the wild. Even if most of the augmented fish die, survivors that mate with wild fish lower the fitness of the endangered population, making the conservation program counter-productive. Since traditional aquaculture programs have been shown to produce fish that are ill-suited to help recovery, a new way of producing fish is needed. That new way is conservation aquaculture. In conservation aquaculture, fish are raised in naturalized mesocosms that mimic the environment in which the endangered species lives. Management is naturalized, so domestication does not produce genetic changes, and so fish develop a full and effective suite of behaviors that enable them to forage efficiently and detect and avoid predators when stocked. The conservation aquaculture management techniques described in the book can also be used to improve commercial and recreational fish stocking programs.
