PART 4 OUTLOOK AND EMERGING ISSUES BLUE GROWTH IN ACTION ser vices provide direct inputs into a blue economy (e.g. fish, water, plants), reg ulating and supporting ser vices are just as crucial, as they provide for healthy aquatic ecosystems that support the economic activities associated with provisioning ser vices (Lillebø et al., 2017). Equally important to blue growth are the cultural ser vices that aquatic ecosystems provide, including tourism and educational opportunities as well as the cultural significance of the ecosystems for many coastal communities (Rodrig ues and Kruse, 2017). Therefore, in the context of blue growth, aquatic resource management needs to consider and balance the importance and use of ecosystem ser vices across all four categories. Achieving this balance is especially vital as the global communit y strives to achieve the SDG goals and targets – especially SDG 14 on oceans – and to ensure the long-term sustainabilit y of aquatic ecosystem use. “Blue growth” is an innovative, integrated and multisectoral approach to the management of aquatic resources aimed at maximizing the ecosystem goods and services obtained from the use of oceans, inland waters and wetlands, while also providing social and economic benefits. Its objective is coordinated management resulting in inclusive growth that contributes to the three pillars of sustainable development (social, economic and environmental) and the alleviation of poverty, hunger and malnutrition (Burgess et al., 2018). Blue growth is anchored in the principle that ecosystem ser vices provided by aquatic ecosystems are fundamental to human well- being – to the air we breathe, the food we consume, and the water we drink and use to grow food. Marine ecosystem ser vices in particular provide more than 60 percent of the economic value of the global biosphere (Martinez et al., 2007). Recognizing this value, the global communit y has been focusing more and more effort on the development of economic capacit y to exploit aquatic ecosystems, and the ser vices they provide, in a sustainable manner. An example of this balance is provided by Bann and Başak (2011), who estimated the economic value of Gökova Turkey Special Environmental Protection Area in Turkey at around USD 31.2 million per year. This value incorporates provisioning services (fish and salt marsh succulents for food), regulating services (carbon sequestration, erosion protection and waste treatment) and cultural services (tourism and recreation). The most economically significant of these services in the area is tourism and recreation, which accounts for approximately 55 percent of the total economic value, highlighting the need to manage the tourism industry sustainably. The use of an ecosystem for economic returns and social benefits must, however, take place in a way that minimizes environmental degradation. If an ecosystem and its ser vices are not maintained, or in some cases restored, the natural capital is eroded and the system will not succeed; it will thus not contribute to improved food securit y and livelihoods or to achieving many SDG goals and targets. Restoring habitat and preser ving biodiversit y can help to improve aquatic ecosystem ser vices and provide numerous benefits in terms of food, revenue and jobs. For example, in Viet Nam, mangrove replanting by volunteers at the cost of USD 1.1 million saved USD 7.3 million annual Ecosystem ser vices are generally divided into four categories (Box 25).
