Some problems may be best addressed by policy instruments that entail community and stakeholder engagement (well established). These include enabling local communities to develop and adopt measures tailored to their context and partnerships with the private sector (well established). {14.2.3}. Policy-sensitive indicators may be used to track progress in addressing key pressures and drivers (well established). These include area-based indicators, such as the coverage of marine protected areas and of vulnerable marine ecosystems. Protected areas under national jurisdiction or in the high seas have the potential to address several pressures relating to marine biodiversity, including overfishing and habitat destruction (well established but incomplete). {14.3.1}. Many indicators may not entirely capture the multiple dimensions of different pressures and drivers (well established). Area-based approaches alone do not gurantee effective area management; nor can they guard against the impact of climate change or pollution (well established). Efforts to develop methods for evaluating the effectiveness of protected areas are, therefore, critical (well established). {14.3.2}. A lack of standardization may make it difficult to track progress towards marine conservation (well established). This is the case of beach litter used as an indicator of litter in the marine environment. The lack of standardization and compatibility between methods used and results obtained in various bottom-up projects makes it difficult to reach an overall assessment of the status of marine litter over large geographical areas {14.3.2}. Responding to key drivers and pressures facing the oceans (e.g. climate change, pollution and overfishing; see Chapter 7 of this report) requires diverse policy instruments and governance approaches (well established). These instruments and approaches include command and control, stakeholder partnerships, economic incentives and approaches to enable actors. {14.2}. Policy coherence and integration are important in addressing cumulative impacts of local and regional threats to support the resilience of marine ecosystems (e.g. coral reefs) to climate change (inconclusive). However, without international policies to curb carbon emissions, the effectiveness of resilience-based management is likely to be very limited, given the limits to the capacity of marine species to adapt to warmer ocean waters (well established). {14.2.1}. Problems involving numerous activities, sectors and sources (e.g. marine litter) may require policies involving comprehensive and coordinated measures (well established but incomplete). When such problems involve multiple jurisdictions, governance approaches to engage neighbouring countries (e.g. the Regional Seas Programme) may be appropriate (well established but incomplete). {14.2.2}. 1 GBRMPA is a federal statutory authority established under the Great Barrier Reef Marine Park Act 1975 with powers to prepare and publish plans and policies relating to the protection and management of the GBR (C...
