Water plays a key role in addressing the most pressing global challenges of our time, including climate change adaptation, food and energy security, environmental sustainability and the promotion of peace and stability. This comprehensive handbook explores the pivotal place of law and policy in efforts to ensure that water enables positive responses to these challenges and provides a basis for sound governance. The book reveals that significant progress has been made in recent decades to strengthen the governance of water resource management at different scales, including helping to address international and sub-national conflicts over transboundary water resources. It demonstrates that ‘effective’ laws and policies are fundamental drivers for the safe, equitable and sustainable utilization of water. However, it is also shown that what might constitute an effective law or policy related to water resources management is still hotly debated. As such, the handbook provides an important and definitive reference text for all studying water governance and management.

Revised to include several recent and important Clean Air Act developments, including the Clear Skies Initiative, this completely updated Handbook provides you with a broad overview of all the complex regulatory requirements of the Act and its amendments. In addition to offering an introduction to the history and structure of the Clean Air Act, the most complex piece of environmental legislation ever enacted, the Handbook examines the Environmental Protection Agency's (EPA) efforts to implement the Act. Those efforts include EPA's initiatives to impose emission reduction requirements through new air quality standards adopted in 1997 and made more stringent in 2006 and EPA's rules and guidance implementing the Title I nonattainment program and ongoing federal efforts to address interstate pollution issues. The Handbook also includes summaries of EPA's rules for state-administered Title V operating permit programs and the key rules promulgated by EPA to implement the Title IV acid rain program.
