• Sommario/riassunto: 'The world has entered the urban millennium. Nearly half the world's people are now city dwellers, and the rapid increase in urban population is expected to continue, mainly in developing countries. This historic transition is being further propelled by the powerful forces of globalization. The central challenge for the international community is clear: to make both urbanization and globalization work for all people, instead of leaving billions behind or on the margins. Cities in a Globalizing World: Global Report on Human Settlements is a comprehensive review of conditions

• Sommario/riassunto: The Ecology of Sandy Shores provides the students and researchers with a one-volume resource for understanding the conservation and management of the sandy shore ecosystem. Covering all beach types, and addressing issues from the behavioral and physiological adaptations of the biota to exploring the effects of pollution and the impact of man's activities, this book should become the standard reference for those interested in Sandy Shore study, management and preservation.* More than 25% expanded from the previous edition* Three entirely new chapters: Energetics and Nutrient
