Two Percent Solutions for the Planet: 50 Low-Cost, Low-Tech, Nature-Based Practices for Combatting Hunger, Drought, and Climate Change

by Courtney White

Two Percent Solutions for the Planet profiles fifty innovative practices that soak up carbon dioxide in soils, reduce energy use, sustainably intensify food production, and increase water quality. The &“two percent&” refers to: the amount of new carbon in the soil needed to reap a wide variety of ecological and economic benefits; the percentage of the nation&’s population who are farmers and ranchers; and the low financial cost (in terms of GDP) needed to get this work done.As White explained in Grass, Soil, Hope, a highly efficient carbon cycle captures, stores, releases, and recaptures biochemical energy, mitigating climate change, increasing water storage capacities in soil, and making green plants grow. Best of all, we don&’t have to invent anything new—a wide variety of innovative ideas and methods that put carbon back into the soil have been field-tested and proven to be practical and profitable. They&’re mostly low-tech, too, relying on natural resources such as sunlight, green plants, animals, compost, beavers, creeks, and more.In Two Percent Solutions for the Planet, White expands what he calls the &“regenerative toolbox,&” to include holistic grazing, edible forests, biochar, weed-eating livestock, food co-ops, keyline plowing, restoration agriculture, bioenergy, aquaponics, animal power, Farm Hack, bees, bears, wildlife corridors, rainwater harvesting, native seeds, and various other projects from across the United States, as well as in Canada, Europe, and Australia. These short, engaging success stories will help readers connect the dots between diverse, exciting, and pragmatic practices, and inspire them to dig deeper into each individual story and concept, energized by the news that solutions do exist.

Two Trees Make a Forest: On Memory, Migration and Taiwan

by Jessica J. Lee

I have learned many words for 'island': isle, atoll, eyot, islet, or skerry. They exist in archipelagos or alone, and always, by definition, I have understood them by their relation to water. But the Chinese word for island knows nothing of water. For a civilisation grown inland from the sea, the vastness of mountains was a better analogue: (dao, 'island') built from the relationship between earth and sky.Between tectonic plates and conflicting cultures, Taiwan is an island of extremes: high mountains, exposed flatlands, thick forests. After unearthing a hidden memoir of her grandfather's life, written on the cusp of his total memory loss, Jessica J Lee hunts his story, in parallel with exploring Taiwan, hoping to understand the quakes that brought her family from China, to Taiwan and Canada, and the ways in which our human stories are interlaced with geographical forces. Part-nature writing, part-biography, Two Trees Make a Forest traces the natural and human stories that shaped an island and a family.

Tying Flood Insurance to Flood Risk for Low-Lying Structures in the Floodplain

by Committee on Risk-Based Methods for Insurance Premiums of Negatively Elevated Structures in the National Flood Insurance Program

Floods take a heavy toll on society, costing lives, damaging buildings and property, disrupting livelihoods, and sometimes necessitating federal disaster relief, which has risen to record levels in recent years. The National Flood Insurance Program (NFIP) was created in 1968 to reduce the flood risk to individuals and their reliance on federal disaster relief by making federal flood insurance available to residents and businesses if their community adopted floodplain management ordinances and minimum standards for new construction in flood prone areas. Insurance rates for structures built after a flood plain map was adopted by the community were intended to reflect the actual risk of flooding, taking into account the likelihood of inundation, the elevation of the structure, and the relationship of inundation to damage to the structure. Today, rates are subsidized for one-fifth of the NFIP's 5. 5 million policies. Most of these structures are negatively elevated, that is, the elevation of the lowest floor is lower than the NFIP construction standard. Compared to structures built above the base flood elevation, negatively elevated structures are more likely to incur a loss because they are inundated more frequently, and the depths and durations of inundation are greater. Tying Flood Insurance to Flood Risk for Low-Lying Structures in the Floodplain studies the pricing of negatively elevated structures in the NFIP. This report review current NFIP methods for calculating risk-based premiums for these structures, including risk analysis, flood maps, and engineering data. The report then evaluates alternative approaches for calculating risk-based premiums and discusses engineering hydrologic and property assessment data needs to implement full risk-based premiums. The findings and conclusions of this report will help to improve the accuracy and precision of loss estimates for negatively elevated structures, which in turn will increase the credibility, fairness, and transparency of premiums for policyholders.

Type-Based Flood Statistics: An Interlink Between Stochastic and Deterministic Flood Hydrology (Water Science and Technology Library #124)

by Andreas H. Schumann Svenja Fischer

This book summarises for the first time all relevant methodologies for type-based flood statistics, introduces the basis of flood typology and makes them accessible to the user. Flood types improve the understanding of the flood-generating processes and characterise the flood event in terms of its features such as peak, volume and hydrograph shape. In addition, they can also significantly expand the information used in flood statistics and add valuable flood characteristics to the determination of design floods, especially the determination of flood scenarios relevant for reservoir management. A detailed framework with all aspects of point and spatial statistics as well as regionalisation is presented, and examples illustrate the benefit of the proposed methodology. The target audience is both users in associations and engineering offices, as type-based statistics are increasingly becoming part of the specifications, and researchers, as this is a current field of research.

U.S. Energy R & D Policy: The Role of Economics (Routledge Revivals)

by John E. Tilton

During the past few decades there has been an advance in the research and development of solving the issue of declining energy resources. Funding by the U.S. government into energy research has risen steeply. Because of the growing importance of research and development in this field of research, in 1973 Resources for the Future undertook a study of energy-associated study, including an investigation of how research on energy R & D itself could be carried out. This title, first published in 1974, assesses a wide range of ways in which economics could contribute to decisions on where and in what amounts government R & D money should be spent. The report also evaluates the research and development approach in relation to other public energy policies or management tools. The book will be of interest to students of environmental studies and economics.

This title will be of interest to students of Environmental Studies and Policy makers.

U.S.-Japanese Agricultural Trade Relations (Routledge Revivals)

by Emery N. Castle Kenzo Hemmi Sally A. Skillings

First published in 1982, the editors and authors of this book examine the United States’ 1973 embargo on the export of soybeans and its effects on U.S.-Japanese relations. Although eventually shipment of soybeans to Japan resumed, the embargo temporarily soured the friendly relations of the two democracies. This book, prepared by a group of Japanese and U.S. scholars, demonstrates how trade relations between the two countries are affected by their internal political situations and by the nature of their respective agricultural industries. U.S.-Japanese Agricultural Trade Relations will be valuable to scholars, policy makers, and others interested in agricultural trade. It should be particularly useful in courses on international trade and on agricultural policy.

U.s. Army Corps Of Engineers Water Resources Planning: A New Opportunity For Service

by Coordinating Committee

From the Executive Summary: There are some concerns that the current Corps planning and construction budget has not kept pace with expanding national water management needs for flood hazard management, water transportation, and other purposes. At the same time, others question the wisdom of and budgetary prospects for the continuation of a traditional water project construction program. Debates about water use and funding priorities now extend to intense scrutiny of Corps of Engineers planning, investment, and project operations programs.

UAVs and Urban Spatial Analysis: An Introduction

by Tony H. Grubesic Jake R. Nelson

This book provides an introduction to the use of unmanned aerial vehicles (UAVs) for the geographic observation and spatial analysis of urban areas. The velocity of urban change necessitates observation platforms that not only enhance situational awareness for planning and allied analytical efforts, but also provide the ability to rapidly and inexpensively collect data and monitor change. UAVs can accomplish both of these tasks, but their use in urban environments is loaded with social, operational, regulatory and technical challenges that must be addressed for successful deployments. The book provides a resource for educators and students who work with geographic information and are seeking to enhance these data with the use of unmanned aerial vehicles. Topics covered include, 1) a primer on UAVs and the many different ways they can be used for geographic observation, 2) a detailed overview on the use of aviation maps and charts for operating UAVs in complex urban airspace, 3) techniques for integrating UAV-derived data with more traditional geographic information, 4) application of spatial analytical tools for urban and environmental planning, and 5) an exploration of privacy and public safety issues associated with UAV operation.

UAVs for Spatial Modelling and Urban Informatics

by Tony H. Grubesic Ran Wei Jake R. Nelson

This book aims to provide a wide range of real-world applications in using unmanned aerial vehicles (UAVs) for geographic observation, spatial modeling, and urban informatics. Specifically, UAVs are incredibly effective platforms for connecting people, places, and technology. This book explores the utility of UAVs for monitoring, measuring, and improving urban infrastructure systems, urban sustainability, and the urban environment. The dynamism of cities provides opportunities for economic, social, and environmental change, but benchmarking and measuring cities continues to be challenging. This challenge is due, at least in part, to a lack of monitoring systems that can collect and analyze data at a granular enough scale to capture the nuance of local phenomena. UAVs offer a promising mechanism to fill this niche, serving as a measurement platform that can rapidly and inexpensively collect data and monitor change in cities. However, their use is fraught with social, operational, regulatory, and technical challenges for successful deployments. This book provides a resource for urbanists (e.g., planners, geographers, sociologists, epidemiologists, engineers), educators, and students who work with geographic information and seek to enhance these data using data and information from unmanned aerial vehicles. At the same time, we provide operational and methodological frameworks for carrying out these advanced analyses in a manner that considers the challenges of incorporating UAVs in research within the urban environment. We provide six unique applications of UAVs for urban analysis, detailing relevant policy and empirical questions, UAV mission parameters, data collection, spatial modeling, and the associated empirical results. Further, we discuss how best to integrate these results into actionable geospatial intelligence and policy development to improve city infrastructure systems, sustainability, the environment, and neighborhood quality.

UK Wind Energy Technologies

by Simon Hogg Christopher J. Crabtree

Phase 1 of the EPSRC SUPERGEN Wind programme began in March 2006 and work continued under Phase 2 until March 2014. The strategic aim was to re-establish a strong research community in wind energy technologies, across the UK’s leading academic and industrial research organisations. UK Wind Energy Technologies gives a comprehensive overview of the range of wind energy research undertaken in the UK under Phases 1 & 2 to achieve this goal. Specific topics covered in the book include: wind resource assessment, turbine array layout, environmental interactions, control of turbines, drive train reliability and condition monitoring, turbine array electrical connection, power transmission to grid, assessment of operations and maintenance strategies, and the analysis of turbine foundations and structures. Since the completion of Phase 2 the Supergen Wind consortium partners have formed a networking Hub, which is now the principal national coordinating body for academic research into wind energy in the UK. This book will be of interest to researchers and engineers from industry and academia and also provides workers from other countries with an overview of the range of activity within the UK resulting from the SUPERGEN Wind programme to date.

UN Human Rights Institutions and the Environment: Synergies, Challenges, Trajectories (Routledge Explorations in Environmental Studies)

by Sumudu Atapattu

This book presents an in-depth analysis of how UN Human Rights institutions and mechanisms have addressed environmental protection, sustainable development and climate change. Despite the increasing involvement of UN human rights bodies in addressing environmental degradation and climate change, a systematic review of the convergence between human rights and the environment in these bodies has not been carried out. Filing this lacuna, this book surveys the resolutions, general comments, concluding observations, decisions on individual communications and press releases. It identifies principles that have emerged, explores the ways in which human rights Charter-based and treaty-based institutions are interpreting environmental principles and examines how they contribute to the emerging field of human rights and environment. Given the disproportionate effect that polluting activities have on marginalized and vulnerable groups, Atapattu also discusses how these human rights mechanisms have addressed the impact on women, children, indigenous peoples, people with disabilities and racial minorities. Written by a world-renowned expert on human rights and the environment, this book will be of great interest to students and scholars researching and teaching in this important field of study.

UN Millennium Development Library: Achieving Gender Equality and Empowering Women

by UN Millennium Project

The Millennium Development Goals, adopted at the UN Millennium Summit in 2000, are the world's targets for dramatically reducing extreme poverty in its many dimensions by 2015 income poverty, hunger, disease, exclusion, lack of infrastructure and shelter while promoting gender equality, education, health and environmental sustainability. These bold goals can be met in all parts of the world if nations follow through on their commitments to work together to meet them. Achieving the Millennium Development Goals offers the prospect of a more secure, just, and prosperous world for all. The UN Millennium Project was commissioned by United Nations Secretary-General Kofi Annan to develop a practical plan of action to meet the Millennium Development Goals. As an independent advisory body directed by Professor Jeffrey D. Sachs, the UN Millennium Project submitted its recommendations to the UN Secretary General in January 2005. The core of the UN Millennium Project's work has been carried out by 10 thematic Task Forces comprising more than 250 experts from around the world, including scientists, development practitioners, parliamentarians, policymakers, and representatives from civil society, UN agencies, the World Bank, the IMF, and the private sector. This report lays out the recommendations of the UN Millennium Project Task Force on Education and Gender Equality. The Task Force recommends seven strategic priorities: strengthen postprimary education for girls while ensuring universal primary education; guarantee sexual and reproductive health and rights; reduce women's and girls' time burdens; guarantee property and inheritance rights; eliminate gender inequality in employment; increase women's participation in government; and significantly reduce violence against women. Action on these priorities will enable countries in every region of the world to achieve gender equality and women's empowerment by 2015.

This report lays out the recommendations of the UN Millennium Project Task Force on Child and Maternal Health. The Task Force recommends the rapid and equitable scale-up of interventions like the Integrated Management of Childhood Illness, the universal provision of emergency obstetric care, and sexual and reproductive health services and rights be provided through strengthened health systems. This will require that health systems be seen as social institutions to which all members of society have a fundamental right. This bold yet practical approach will enable every country to reduce the under-five mortality rate by two-thirds and the maternal mortality rate by three-quarters by 2015.

In this report the UN Millennium Project Task Force on Water and Sanitation outlines the bold yet practical actions that are needed to increase access to water and sanitation. The report underscores the need to focus on the global sanitation crisis, which contributes to the death of 3900 children each day, improve domestic water supply, and invest in integrated development and management of water resources, all of which are necessary for countries to reduce poverty and hunger, improve health, advance gender equality and ensure environmental sustainability. Implementing the recommendations of this report will allow all countries to halve the proportion of people without access to safe water and sanitation by 2015.

UNDER THE WEATHER: Climate, Ecosystems, and Infectious Disease

by National Research Council

Since the dawn of medical science, people have recognized connections between a change in the weather and the appearance of epidemic disease. With today's technology, some hope that it will be possible to build models for predicting the emergence and spread of many infectious diseases based on climate and weather forecasts. However, separating the effects of climate from other effects presents a tremendous scientific challenge.Can we use climate and weather forecasts to predict infectious disease outbreaks? Can the field of public health advance from "surveillance and response" to "prediction and prevention?" And perhaps the most important question of all: Can we predict how global warming will affect the emergence and transmission of infectious disease agents around the world?Under the Weather evaluates our current understanding of the linkages among climate, ecosystems, and infectious disease; it then goes a step further and outlines the research needed to improve our understanding of these linkages. The book also examines the potential for using climate forecasts and ecological observations to help predict infectious disease outbreaks, identifies the necessary components for an epidemic early warning system, and reviews lessons learned from the use of climate forecasts in other realms of human activity.

UNDERSTANDING MULTIPLE Environmental STRESSES: REPORT OF A WORKSHOP

by National Research Council of the National Academies

The research of the last decade has demonstrated that ecosystems and human systems are influenced by multiple factors, including climate, land use, and the by-products of resource use. Understanding the net impact of a suite of simultaneously occurring environmental changes is essential for developing effective response strategies. Using case studies on drought and a wide range of atmosphere-ecosystem interactions, a workshop was held in September 2005 to gather different perspectives on multiple stress scenarios. The overarching lesson of the workshop is that society will require new and improved strategies for coping with multiple stresses and their impacts on natural socioeconomic systems. Improved communication among stakeholders; increased observations (especially at regional scales); improved model and information systems; and increased infrastructure to provide better environmental monitoring, vulnerability assessment, and response analysis are all important parts of moving toward better understanding of and response to situations involving multiple stresses. During the workshop, seven near-term opportunities for research and infrastructure that could help advance understanding of multiple stresses were also identified.

UNESCO Biosphere Reserves: Supporting Biocultural Diversity, Sustainability and Society (Earthscan Studies in Natural Resource Management)

by Martin F. Price Maureen G. Reed

UNESCO Biosphere Reserves (BRs) are designated areas in geographical regions of global socio-ecological significance. This definitive book shows their global relevance and contribution to environmental protection, biocultural diversity and education. Initiated in the 1970s as part of UNESCO’s Man and Biosphere (MAB) Programme, BRs share a set of common objectives, to support and demonstrate a balance between biodiversity conservation, sustainable development and research. The world’s 701 BRs form an international, intergovernmental network to support the aims of sustainability science, but this purpose has not always been widely understood. In three distinct sections, the book starts by outlining the origins of BRs and the MAB Programme, showing how they contribute to advancing sustainable development. The second section documents the evolution of BRs around the world, including case studies from each of the five UNESCO world regions. Each case study demonstrates how conservation, sustainable development and the role of scientific research have been interpreted locally. The book concludes by discussing thematic lessons to help understand the challenges and opportunities associated with sustainability science, providing a unique platform from which lessons can be learned. This includes how concepts become actions on the ground and how ideas can be taken up across sites at differing scales. This book will be of great interest to professionals engaged in conservation and sustainable development, NGOs, policy-makers and advanced students in environmental management, ecology, sustainability science, environmental anthropology and geography.
