The countries of the Black Sea region are beset by a great number of problems: there are many large cities along the coast; intensive agriculture is practised in the region; great rivers such as the Danube and the Dnieper carry pollution from a large part of Europe; and the lowlands are threatened by flooding from the rivers, wind-induced surges, and future sea-level rise due to global warming. Any integrated, sustainable development of the region will require an interdisciplinary approach, which the present book reflects. Contributions range from the monitoring of biological diversity through the influence of tourism on marine and coastal ecosystems to environmental economics. The problem also has an international dimension: only by interdisciplinary, international co-operation can the environment of the Black Sea region be conserved for future generations.
