Ocean conservation boosts climate change mitigation and adaptation

One Earth, Год журнала: 2022, Номер 5(10), С. 1126 - 1138

Опубликована: Окт. 1, 2022

Marine protected areas (MPAs) are increasingly being promoted as an ocean-based climate solution. However, such claims remain controversial because of the diffuse and poorly synthesized literature on benefits MPAs. To address this knowledge gap, we conducted a systematic review 22,403 publications spanning 241 MPAs analyzed these across 16 ecological social pathways through which could contribute to change mitigation adaptation. Our meta-analysis demonstrates that marine conservation can significantly enhance carbon sequestration, coastal protection, biodiversity, reproductive capacity organisms well fishers' catch income. Most only achieved in fully or highly increase with MPA age. Although alone cannot offset all impacts, they useful tool for adaptation social-ecological systems.

Ocean protection quality is lagging behind quantity: Applying a scientific framework to assess real marine protected area progress against the 30 by 30 target

Conservation Letters, Год журнала: 2024, Номер 17(3)

Опубликована: Май 1, 2024

Abstract The international community set a global conservation target to protect at least 30% of the ocean by 2030 (“30 × 30”) reverse biodiversity loss, including through marine protected areas (MPAs). However, varied MPAs result in significantly different outcomes, making MPA coverage alone an inadequate metric. We used Guide framework assess world's largest 100 area, representing nearly 90% reported and 7.3% analyzed distribution quality across political ecological regions. A quarter assessed is not implemented, one‐third incompatible with nature. Two factors contribute this outcome: (1) many lack regulations or management, (2) some allow high‐impact activities. Fully highly account for area but are unevenly distributed ecoregions part because nations have designated large, their overseas remote territories. Indicators quality, only coverage, needed ensure network that covers effectively safeguards representative ecosystems from destructive human

Population declines of vertebrates are common, but rebuilding marine life may be possible. We assessed trends in sea turtle numbers globally, building 61 time series abundance extending beyond 2015, representing monitoring >1200 years. Increases were widespread with significant upward trends, no change, and downward 28, 5 series, respectively. For example, annual nest increased between 1980 2018 from around 4,000 to 16,000 for green turtles at Aldabra (Seychelles, Indian Ocean) 2008 2020 500 35,000 loggerhead Sal (Cape Verde, north Atlantic). However, conservation concerns remain. Major populations experience declines, such as Oman, while previous can reversed, nesting Tortuguero (Costa Rica, Caribbean). Further, decreases evident several leatherback series. These show there is room complacency conservation.

Making up over 92% of life in our oceans, marine invertebrates inhabit every zone the water column, with contributions ranging from ecosystem functioning to socioeconomic development. Compared charismatic species, are often underrepresented IUCN reports and national conservation efforts. Because this, as climate change intensifies conjunction increasing anthropogenic pressures such habitat destruction, many at risk silently heading toward extinction. However, public perception has shifted recent years due growing awareness important roles these play human life. This may promote greater support for future research campaigns key species. review highlights importance invertebrates, environmental stressors they currently facing, inherent challenges their successful conservation.

The ecology and function of rocky temperate mesophotic ecosystems (TMEs) remain poorly understood globally despite their widespread distribution. They typically occur at 20-150 m (the limit photosynthesis), on substratum they support rich benthic communities mobile fauna. We determined the distribution TMEs, conservation status, most characteristic biological groups. Rocky TMEs were dominated by algae, turf-invertebrate matrices (<50 only), sponges, bryozoans, cnidarians. community composition differed significantly from shallow (0-15 m) subtidal reefs. Data geographically biased variable, available only North South Atlantic, Mediterranean, Temperate Australasia. Degree protection varied considerably across world. biggest threats to identified changes in temperature, sedimentation rates, nutrient concentrations, certain fishing types. propose a framework inform future TME management conservation, highlighting need recognize importance these biologically diverse functionally important ecosystems.

Marine protected areas (MPAs) are a key tool for achieving goals biodiversity conservation and human well-being, including improving climate resilience equitable access to nature. At national level, they central components in the U.S. commitment conserve at least 30% of waters by 2030. By definition, primary goal an MPA is long-term nature; however, not all MPAs provide same ecological social benefits. A system that equitable, well-managed, representative connected, includes level protection can deliver desired outcomes best positioned support goals. We used new framework, The Guide, assess stage establishment 50 largest MPAs, which make up 99.7% total area (3.19 million km 2 ).

Marine protected areas (MPAs) are an important tool in helping to protect biodiversity the oceans. Recent ratification of Kunming-Montreal Global Biodiversity Framework (GBF) has ensured that globally we committed effectively protecting 30% world’s oceans by 2030, MPAs. In Australia there is considerable interest potential benefits partially (PPAs) may provide. However, a consistent definition PPA currently lacking, and urgently needed conduct quantitative analyses PPAs. We conducted systematic literature review understand current knowledge surrounding PPAs their benefits. define PPA, characterise implementation Australia, present results for outcomes terms ecological, economic, social indicators. Our suggests although 45% Australia’s marine environment within MPAs, 61% MPAs provide only partial protection. The Northern Territory (100%), New South Wales (81%), Queensland (79.8%) have highest percentage protected, compared Tasmania which smallest (13.12%). also cover (6.49% state waters). Most management plans did not contain quantifiable Key Performance Indicators (KPIs) be able monitor progress these against stated outcomes. find ambiguous: generally when ‘open’ ocean, however this result.
