Using the experiences of large water infrastructure projects involving the transfer of water from basins considered to have surplus water to those where the demand for water has exceeded or is expected to exceed supplies, this book examines case studies within diverse geographical, climatic, economic, and policy regimes.

In December 2002, a group of specialists on water resources from the United States and Iran met in Tunis, Tunisia, for an interacademy workshop on water resources management, conservation, and recycling. This was the fourth interacademy workshop on a variety of topics held in 2002, the first year of such workshops. Tunis was selected as the location for the workshop because the Tunisian experience in addressing water conservation issues was of interest to the participants from both the United States and Iran. This report includes the agenda for the workshop, all of the papers that were presented, and the list of site visits.

Underground the way to the future was the motto of the World Tunnel Congress 2013 in Geneva, Switzerland. The use of underground space has gained importance during the last years due to the tremendous global urbanization, the high demand on transportation capacities and energy production.

The Mexican -- United States border represents much more than the meeting place of two nations. Our border communities are often a line of first defense -- absorbing the complex economic, environmental and social impacts of globalization that ripple through the region. In many ways, our success or failure in finding solutions for the environmental, social and economic issues that plague the region may well define our ability to meet similar challenges thousands of miles from the border zone. Border residents face the environmental security concerns posed by water scarcity and transboundary air pollution; the planning and infrastructure needs of an exploding population; the debilitating effects of inadequate sanitary and health facilities; and the crippling cycle of widespread poverty. Yet, with its manifold problems, the border area remains an area of great dynamism and hope -- a multicultural laboratory of experimentation and grass-roots problem-solving. Indeed, as North America moves towards a more integrated economy, citizen action at the local level is pushing governments to adapt to the driving forces in the border area by creating new institutional arrangements and improving old ones. If there is one defining feature of this ground-up push for more responsive transboundary policies and institutions, it is a departure from the closed, formalistic models of the past to a more open, transparent and participatory model of international interaction.
