In the course of the last two decades, the estimated loss of seagrass from direct and indirect human impacts amounts to at least 29% of the documented seagrass area, with a global loss rate (≈7% yr −1 ) faster than that of tropical rainforests (Waycott et al, 2009).…”

Assessment of goods and services, vulnerability, and conservation status of European seabed biotopes: a stepping stone towards ecosystem-based marine spatial management

The goal of ecosystem-based marine spatial management is to maintain marine ecosystems in a healthy, productive and resilient condition; hence, they can sustainably provide the needed goods and services for human welfare. However, the increasing pressures upon the marine realm threaten marine ecosystems, especially seabed biotopes, and thus a well-planned approach of managing use of marine space is essential to achieve sustainability. The relative value of seabed biotopes, evaluated on the basis of goods and services, is an important starting point for the spatial management of marine areas. Herein, 56 types of European seabed biotopes and their related goods, services, sensitivity issues, and conservation status were compiled, the latter referring to management and protection tools which currently apply for these biotopes at European or international level. Fishing activities, especially by benthic trawls, and marine pollution are the main threats to European seabed biotopes. Increased seawater turbidity, dredged sediment disposal, coastal constructions, biological invasions, mining, extraction of raw materials, shipping-related activities, tourism, hydrocarbon exploration, and even some practices of scientific research, also exert substantial pressure. Although some first steps have been taken to protect the European sea beds through international agreements and European and national legislation, a finer scale of classification and assessment of marine biotopes is considered crucial in shaping sound priorities and management guidelines towards the effective conservation and sustainability of European marine resources.

“…Although new institutions, in particular the Black Sea Commission, came into being and have been supported by the European Union (EU) and the United Nations (UN), these are constrained in terms of actions and political influence by political problems between member states. Indeed, a new push for agricultural development without sufficient measures to limit nutrient inputs could return the system to its collapsed resilient state (Mee 2006, Langmead et al 2009). …”

“…At a European regional seas scale, Langmead et al (2009) applied scenarios to model the potential environmental consequences of changes in social and economic drivers in the 16-country Black Sea basin. (Five different sociopolitical scenarios were modeled, most of which projected an increase in nutrient loads to the Sea and a return of the "dead zone" unless explicit actions were taken to curb them and to correct current overfishing.…”

ABSTRACT. Marine environments have undergone large-scale changes in recent decades as a result of multiple anthropogenic pressures, such as overfishing, eutrophication, habitat fragmentation, etc., causing often nonlinear ecosystem responses. At the same time, management institutions lack the appropriate measures to address these abrupt transformations. We focus on existing examples from social-ecological systems of European seas that can be used to inform and advise future management. Examples from the Black Sea and the Baltic Sea on long-term ecosystem changes caused by eutrophication and fisheries, as well as changes in management institutions, illustrate nonlinear dynamics in social-ecological systems. Furthermore, we present two major future challenges, i.e., climate change and energy intensification, that could further increase the potential for nonlinear changes in the near future. Practical tools to address these challenges are presented, such as ensuring learning, flexibility, and networking in decision-making processes across sectors and scales. A combination of risk analysis with a scenario-planning approach might help to identify the risks of ecosystem changes early on and may frame societal changes to inform decision-making structures to proactively prevent drastic surprises in European seas.

“…The driver, pressure, state, impact, response (DPSIR) cycle and its successors, modified DPSIR (mDPSIR; Langmead et al 2009, Knudsen et al 2010, Atkins et al 2011) and DPSWR where the term impact is replaced with welfare (Cooper 2013), are well tested and widely used conceptual frameworks for analysis of social/ ecological problems including in marine systems (Borja et al 2006, Langmead et al 2009, Knudsen et al 2010, Atkins et al 2011); here we follow Cooper's DPSWR model (2013). Drivers are economic and social forces resulting from government policies, markets, and private industry.…”

ABSTRACT. The Black Sea has suffered severe environmental degradation. Governance of the Black Sea region is complex and results in a series of scale mismatches which constrain management. This paper develops a simple classification of spatial scale mismatches incorporating the driver, pressure, state, welfare, response (DPSWR) framework. The scale mismatch classification is applied to two major environmental problems of the Black Sea, eutrophication and small pelagic fisheries. A number of scale mismatches are described and classified and potential solutions are identified.
