The rapid urbanization that began with industrialization has begun to cause many problems. New approaches are emerging today to minimize these problems and make urban areas more livable. These problems include insufficient social facilities in urban areas for increasing populations due to migration and unbalanced use of green areas, water, and energy resources due to urbanization. Careless consumption and the pollution of natural resources will cause people many more problems in the future than they do today in urban development. Many professional disciplines have noticed this unbalanced development in urban areas. Urban areas have larger populations than rural areas today. Urban areas are developed neglectfully. Sustainability is needed as a criterion for urban areas to develop in a more livable and healthy fashion. Sustainable urban development approaches are seen in many fields, ranging from land use to the use of natural resources in urban areas.

Scallops: Biology, Ecology, Aquaculture and Fisheries, Third Edition, continues its history as the definitive resource on scallops, covering all facets of scallop biology, including anatomy, taxonomy, physiology, ecology, larval biology, and neurobiology. More than thirty extensive chapters explore both fisheries and aquaculture for all species of scallops in all countries where they are fished or cultured. This treatise has been updated to include the most recent advances in research and the newest developments within the industry. As aquaculture remains one of the fastest-growing animal food-producing sectors, this reference becomes even more vital. It has all the available information on scallops needed to equip researchers to deal with the unique global issues in the field. - Offers 30 detailed chapters on the development and ecology of scallops - Provides chapters on various cultures of scallops in China, Japan, Scandinavia, Europe, Eastern North America, and Western North America - Includes details of scallop reproduction, nervous system, and behavior, genetics, diseases, parasites, and much more - Completely updated edition with valuable information on one of the most widely distributed shellfish in the world

Fish bones in the caves of East Timor reveal that humans have systematically fished the seas for at least 42,000 years. But in recent centuries, our ancient, vital relationship with the oceans has changed faster than the tides. As boats and fishing technology have evolved, traditional fishermen have been challenged both at sea and in the marketplace by large-scale fishing companies whose lower overhead and greater efficiency guarantee lower prices. In Fishing Lessons, Kevin M. Bailey captains a voyage through the deep history and present course of this sea change—a change that has seen species depleted, ecosystems devastated, and artisanal fisheries transformed into a global industry afloat with hundreds of billions of dollars per year. Bailey knows these waters, the artisanal fisheries, and their relationship with larger ocean ecology intimately. In a series of place-based portraits, he shares stories of decline and success as told by those at the ends of the long lines and hand lines, channeling us through the changing dynamics of small-scale fisheries and the sustainability issues they face—both fiscal and ecological. We encounter Paolo Vespoli and his tiny boat, the Giovanni Padre,in the Gulf of Naples; Wenche, a sea Sámi, one of the indigenous fisherwomen of Norway; and many more. From salmon to abalone, the Bay of Fundy to Monterey and the Amazon, Bailey’s catch is no fish tale. It is a global story, casting a net across waters as vast and distinct as Puget Sound and the Chilean coast. Sailing across the world, Bailey explores the fast-shifting current of how we gather food from the sea, what we gain and what we lose with these shifts, and potential solutions for the murky passage ahead.
