Britain has brought online a new desalination plant near London capable of providing the city with 150 million gallons (568 million litres) of water per day, should the need arise. At a cost of £270 ($445) million, and built over the past four years, the plant uses reverse osmosis to remove salt from the brackish water pumped in from the Thames Estuary, which it then pumps into local reservoirs, thus staving off the threat of drought.

Large increases in urbanization can lead to more concrete and asphalt reducing an area's flood mitigation services. Low density housing, however, has little effect on flood mitigation services but does cut down losses in the amount of land available for food and carbon storage, the study showed. Researchers investigated how a projected 16 per cent increase in the human population in Britain by 2031 would affect key ecosystem services depending on how cities expanded to meet the growing demand.

essays in this book reflect pioneering efforts to study the global movement of ideas and institutions. They deal with topics of significant contemporary importance: initiatives to address the AIDS epidemic in East Africa; to protect the peoples and ecosystems of the Amazon; to advance the "truth and reconciliation" process in South Africa and in other areas of great conflict; to promote "civil society" in Eastern Europe and Central Asia; to advocate for environmental protection in the United States, Great Britain, Germany, and Japan; and to spread Rotary Clubs and encourage "social entrepreneurship" throughout the world. These essays highlight a wide range of research, paying close attention to the realities of particular situations and to current thinking about general processes.
