A Sea Change: The Exclusive Economic Zone and Governance Institutions for Living Marine Resources
A Sea Change in a Changing Sea The oceans, seas and coastal areas encompass over 70% of the earth’s surface. They are a critical driver of the earth’s hydrologic cycle and climate system, important for c- merce, transport, and tourism, a source of economically important living marine resources, minerals such as hydrocarbons, as well as new pharmaceutical compounds. The marine environment provides essential habitats for thousands of marine living 1 2 resources, which in turn contribute significantly to global food security, employment, 3 and trade. Overall, the sea’s contribution to human welfare, in terms of market and non-market resources and environmental services, has been estimated at US$21 trillion/year (Costanza, 2000). However, despite the importance of the ocean realm to humans, there is a growing sense that human impacts are destabilizing this system. Some experts believe that current fishing levels are approaching or exceeding the total 4 productivity of the ocean ecosystem (National Research Council, 1999).
Marine Resource Conservation and Poverty Reduction Strategies in Tanzania
Despite the social, nutritional, economical and environmental importance of Tanzanian coastal areas, yet they are vulnerable to both over-exploitation and degradation of their habitats. Using the data from two coastal villages and econometric methods as well as Stochastic Production Frontier techniques, the book demonstrates the extent which various socio-economic dimensions of rural coastal households influence livelihood pathways, production efficiency and attitudes towards conservation initiatives. Thus, attention to differential patterns of rural coastal households presents more viable possibilities for coastal villages to have conservation-development policies/programs that lead to poverty reduction.
Aquaculture Perspective of Multi-Use Sites in the Open Ocean : The Untapped Potential for Marine Resources in the Anthropocene
This volume addresses the potential for combining large-scale marine aquaculture of macroalgae, molluscs, crustaceans, and finfish, with offshore structures, primarily those associated with energy production, such as wind turbines and oil-drilling platforms. The volume offers a comprehensive overview and includes chapters on policy, science, engineering, and economic aspects to make this concept a reality. The compilation of chapters authored by internationally recognized researchers across the globe addresses the theoretical and practical aspects of multi-use, and presents case studies of research, development, and demonstration-scale installations in the US and EU
