Book Description
"Leading the way describes how the men and women of Air Force civil engineering have provided the basing that enabled the Air Force to fly, fight, and win. This book depicts how engineers built hundreds of bases during World Wars I and II, Korea, Vietnam, the Gulf War, and Operations Enduring Freedom and Iraqi Freedom. At the same time, these engineers operated and maintained a global network of enduring, peacetime bases. It describes the engineers' role in special projects such as the ballistic missile program, the Arctic early warning sites, and construction of the U.S. Air Force Academy. Using hundreds of sources, this detailed narrative tells the story of how civil engineers have been organized, trained, equipped, and employed for more than 100 years. From the beaches of Normandy to the mountains of Afghanistan, civil engineers have forged an unmatched record of success and built a solid foundation for today's Air Force."--Back cover.

Book Description
For nearly a century, scientific advances have fueled progress in U.S. agriculture to enable American producers to deliver safe and abundant food domestically and provide a trade surplus in bulk and high-value agricultural commodities and foods. Today, the U.S. food and agricultural enterprise faces formidable challenges that will test its long-term sustainability, competitiveness, and resilience. On its current path, future productivity in the U.S. agricultural system is likely to come with trade-offs. The success of agriculture is tied to natural systems, and these systems are showing signs of stress, even more so with the change in climate. More than a third of the food produced is unconsumed, an unacceptable loss of food and nutrients at a time of heightened global food demand. Increased food animal production to meet greater demand will generate more greenhouse gas emissions and excess animal waste. The U.S. food supply is generally secure, but is not immune to the costly and deadly shocks of continuing outbreaks of food-borne illness or to the constant threat of pests and pathogens to crops, livestock, and poultry. U.S. farmers and producers are at the front lines and will need more tools to manage the pressures they face. Science Breakthroughs to Advance Food and Agricultural Research by 2030 identifies innovative, emerging scientific advances for making the U.S. food and agricultural system more efficient, resilient, and sustainable. This report explores the availability of relatively new scientific developments across all disciplines that could accelerate progress toward these goals. It identifies the most promising scientific breakthroughs that could have the greatest positive impact on food and agriculture, and that are possible to achieve in the next decade (by 2030).

Book Description
The economic activity that drives growth in developing countries is heavily concentrated in cities. Catchphrases such as “metropolitan areas are the engines that pull the national economy” turn out to be fairly accurate. But the same advantages of metropolitan areas that draw investment also draw migrants who need jobs and housing, lead to demands for better infrastructure and social services, and result in increased congestion, environmental harm, and social problems. The challenges for metropolitan public finance are to capture a share of the economic growth to adequately finance new and growing expenditures and to organize governance so that services can be delivered in a cost-effective way, giving the local population a voice in fiscal decision making. At the same time, care must be taken to avoid overregulation and overtaxation, which will hamper the now quite mobile economic engine of private investment and entrepreneurial initiative. Metropolitan planning has become a reality in most large urban areas, even though the planning agencies are often ineffective in moving things forward and in linking their plans with the fiscal and financial realities of metropolitan government. A growing number of success stories in metropolitan finance and management, together with accumulated experience and proper efforts and support, could be extended to a broader array of forward-looking programs to address the growing public service needs of metropolitan-area populations. Nevertheless, sweeping metropolitan-area fiscal reforms have been few and far between; the urban policy reform agenda is still a long one; and there is a reasonable prospect that closing the gaps between what we know how to do and what is actually being done will continue to be difficult and slow. This book identifies the most important issues in metropolitan governance and finance in developing countries, describes the practice, explores the gap between practice and what theory suggests should be done, and lays out the reform paths that might be considered. Part of the solution will rest in rethinking expenditure assignments and instruments of finance. The “right” approach also will depend on the flexibility of political leaders to relinquish some control in order to find a better solution to the metropolitan finance problem.

Book Description
The second half of the 20th century and the beginning of the 21st century witnessed important changes in ecology, climate and human behaviour that favoured the development of urban pests. Most alarmingly, urban planners now face the dramatic expansion of urban sprawl, in which city suburbs are growing into the natural habitats of ticks, rodents and other pests. Also, many city managers now erroneously assume that pest-borne diseases are relics of the past. All these changes make timely a new analysis of the direct and indirect effects of present-day urban pests on health. Such an analysis should lead to the development of strategies to manage them and reduce the risk of exposure. To this end, WHO invited international experts in various fields - pests, pest-related diseases and pest management - to provide evidence on which to base policies. These experts identified the public health risk posed by various pests and appropriate measures to prevent and control them. This book presents their conclusions and formulates policy options for all levels of decision-making to manage pests and pest-related diseases in the future. [Ed.]
