Book Description
When waterfowl began to die from selenium poisoning at Kesterson National Wildlife Refuge in California's San Joaquin Valley, considerable alarm arose among environmental and agricultural specialists. This new volume suggests that Kesterson is not a unique problem and the events there offer important lessons for the future. Irrigation-Induced Water Quality Problems uses the San Joaquin experience to suggest how we can prepare for similar problems elsewhere. As one committee member put it, "There will be elsewheres"â€"trace elements and organic contaminants are being concentrated by irrigation in many river basins. This book addresses how the Kesterson crisis developed, how irrigation can endanger water quality, and how economic, legal, and other factors impede our ability to respond to water quality problems. The committee explores how to study these problems, unraveling complex issues and clarifying the varying perspectives of farmers, environmentalists, scientists, and other key figures. This dispassionate analysis of a controversial topic will be useful to policymakers, resource managers, and agricultural specialists and farmers, as well as specialists in hydrology, water quality, irrigation, law, and environmental quality. It will also be useful as a case study in the environmental policy classroom.

Book Description
Improvised explosive devices (IEDs) are a type of unconventional explosive weapon that can be deployed in a variety of ways, and can cause loss of life, injury, and property damage in both military and civilian environments. Terrorists, violent extremists, and criminals often choose IEDs because the ingredients, components, and instructions required to make IEDs are highly accessible. In many cases, precursor chemicals enable this criminal use of IEDs because they are used in the manufacture of homemade explosives (HMEs), which are often used as a component of IEDs. Many precursor chemicals are frequently used in industrial manufacturing and may be available as commercial products for personal use. Guides for making HMEs and instructions for constructing IEDs are widely available and can be easily found on the internet. Other countries restrict access to precursor chemicals in an effort to reduce the opportunity for HMEs to be used in IEDs. Although IED attacks have been less frequent in the United States than in other countries, IEDs remain a persistent domestic threat. Restricting access to precursor chemicals might contribute to reducing the threat of IED attacks and in turn prevent potentially devastating bombings, save lives, and reduce financial impacts. Reducing the Threat of Improvised Explosive Device Attacks by Restricting Access to Explosive Precursor Chemicals prioritizes precursor chemicals that can be used to make HMEs and analyzes the movement of those chemicals through United States commercial supply chains and identifies potential vulnerabilities. This report examines current United States and international regulation of the chemicals, and compares the economic, security, and other tradeoffs among potential control strategies.

Book Description
The infiltration approach to stormwater management involves the design, construction, and operation of engineered systems that infiltrate stormwater runoff into soils. These systems, referred to as "infiltration best management practices (BMPs)," are intended to reduce the volume of stormwater runoff and associated pollutants that discharge to stormwater systems and receive waters via surface runoff. The TRB National Cooperative Highway Research Program's NCHRP Research Report 922: Stormwater Infiltration in the Highway Environment: Guidance Manual supports evaluation, selection, siting, design, and construction of infiltration BMPs in the highway environment. It is also intended to identify limitations on the use of infiltration and determine the need for alternative non-infiltration-based stormwater management approaches.

Book Description
There is growing enthusiasm in the scientific community about the prospect of mapping and sequencing the human genome, a monumental project that will have far-reaching consequences for medicine, biology, technology, and other fields. But how will such an effort be organized and funded? How will we develop the new technologies that are needed? What new legal, social, and ethical questions will be raised? Mapping and Sequencing the Human Genome is a blueprint for this proposed project. The authors offer a highly readable explanation of the technical aspects of genetic mapping and sequencing, and they recommend specific interim and long-range research goals, organizational strategies, and funding levels. They also outline some of the legal and social questions that might arise and urge their early consideration by policymakers.

Book Description
Bangladesh’s vulnerability to the effects of climate change is well documented; the evidence on the direct relationship between climate change and health focusing on Bangladesh is less so. Global evidence suggests intensification of climate change will increase incidences and variations of infectious diseases. Climate Afflictions contributes to filling this important knowledge gap. It includes a systematic review of existing literature on the relationship between climate change and health, distinguishing between climate change and variability. It establishes the relationship between climate variability and infectious diseases and mental health using household-level data. It also documents changes in climate patterns in Bangladesh over the past 44 years using monthly meteorological data. Overall, the report finds a strong relationship between infectious diseases, mental health, and climate variability. Based on analyses of primary data, it concludes that the prevalence of vector-borne diseases is higher during the monsoon than dry seasons, while the opposite is true for waterborne illnesses. Meanwhile, rising humidity and mean temperature are positively associated with respiratory illnesses. In terms of mental health conditions, while temperature is negatively correlated to depression, anxiety among individuals is likely to increase with temperature and humidity. Irrespective of the season, morbidity and mental health issues are highest in densely populated urban hubs such as Dhaka and Chattogram compared to other areas. The mean temperature in Bangladesh has increased by 0.5°C between 1976 and 2019. Overall, summers are becoming hotter and longer, the monsoon season is extending, and winters are becoming warmer. Consequently, Bangladesh is on the path to losing its distinct seasonality. With global warming progressing faster than initially projected, stresses on human health may be elevated to an extent that can overburden the systems to a point at which adaptation will no longer be possible. Countries susceptible to climate change, like Bangladesh, need to be better prepared.

Book Description
Engineering skills and knowledge are foundational to technological innovation and development that drive long-term economic growth and help solve societal challenges. Therefore, to ensure national competitiveness and quality of life it is important to understand and to continuously adapt and improve the educational and career pathways of engineers in the United States. To gather this understanding it is necessary to study the people with the engineering skills and knowledge as well as the evolving system of institutions, policies, markets, people, and other resources that together prepare, deploy, and replenish the nation's engineering workforce. This report explores the characteristics and career choices of engineering graduates, particularly those with a BS or MS degree, who constitute the vast majority of degreed engineers, as well as the characteristics of those with non-engineering degrees who are employed as engineers in the United States. It provides insight into their educational and career pathways and related decision making, the forces that influence their decisions, and the implications for major elements of engineering education-to-workforce pathways.

Book Description
Human capital is a central determinant of economic well-being and social advancement in the modern world economy. The concept of human capital covers the knowledge, skills, nutrition, and health that people accumulate over their lives, enabling them to realize their potential as productive members of society. Because of the vital importance of human capital for economic growth, the World Bank has launched the Human Capital Project (HCP), which includes the Human Capital Index (HCI). The objective of the HCP is to accelerate human capital development around the world. The HCI is a cross-country metric designed to measure and forecast a country’s human capital. Sri Lanka is a lower-middle-income country seeking to become an upper-middle-income country. Developing human capital to a new and higher level will be central to achieving this development goal. After the country’s 26-year secessionist conflict ended in 2009, Sri Lanka’s economy enjoyed rapid growth at an average rate of almost 6 percent between 2010 and 2017, reflecting a peace dividend and a determined policy thrust toward reconstruction and growth. However, in more recent years there have been signs of a slowdown. The economy is transitioning from a predominantly rural economy to a more urbanized one. In the context of the HCP and the HCI, Sri Lanka Human Capital Development analyzes the main achievements and challenges of human capital development in this East Asia and Pacific island country in health and nutrition—including stunting—and in education—including the challenges posed by Sri Lankans’ low participation in higher education. The report concludes with a look at the importance of building a consensus among the public and other stakeholders to launch an ambitious human capital development program in Sri Lanka.

Book Description
Recognizing that services affect the ability of countries and their firms to compete on international markets, the World Bank’s Trade and Regional Integration Unit has developed an extensive work program to promote the performance of countries’ domestic services sectors, including services trade. Services for Trade Competitiveness presents selected applications of new methodologies that were developed to assess the competitiveness of countries’ services sectors, discern the types of barriers to services that exist in the regulatory environment, and identify the resulting policy implications. Its assessments are designed for a wide audience, including policy makers in developing countries and development practitioners in international organizations, policy-making institutions, and academia. The purpose of this book is to help policy makers in developing countries make informed policy choices to increase their chances of benefiting from the increasing prominence of services in international trade.
