This plan outlines and prices a 20-year strategy for protecting the quality of ground and surface waters. In meeting the requirements of Section 208 of the Federal Water Pollution Control Act Amendments of 1972, the plan considers all significant pollution sources including municipal and industrial discharge, agricultural runoff, urban stormwater runoff, mining activities, construction activities, natural salt water intrusion, and residual wastes such as water and wastewater treatment sludges.

"This guidance is intended to provide U.S. Department of Housing and Urban Development (HUD) grantees with information regarding barrier design that will protect HUD-assisted projects from facilities that may pose an explosive or flammable hazard." --P.1.

The two pre-World War I generations encompassed the greatest innovative period in history. Technical inventions of 1867-1914 & their rapid improvement & commercialisation created new prime movers, materials, infrastructures & information means that provided the lasting foundations of the modern world.

During the last 100 years, the worldwide yields of cereal grains, such as wheat and rice, have increased dramatically. Since the 1950s, developments in plant breeding science have been heralded as a "Green Revolution" in modern agriculture. But what factors have enabled and promoted these technical changes? And what are the implications for the future of agriculture? This new book uses a framework of political ecology and environmental history to explore the "Green Revolution's" emergence during the 20th century in the United States, Mexico, India, and Britain. It argues that the national security planning efforts of each nation were the most important forces promoting the development and spread of the "Green Revolution"; when viewed in the larger scheme, this period can be seen as the latest chapter in the long history of wheat use among humans, which dates back to the neolithic revolution. Efforts to reform agriculture and mitigate some of the harsh environmental and social consequences of the "Green Revolution" have generally been insensitive to the deeply embedded nature of high yielding agriculture in human ecology and political affairs. This important insight challenges those involved in agriculture reform to make productivity both sustainable and adequate for a growing human population.
