10 What does OECM stand for? The term ‘other effective area-based conservation measure’ describes a geographic site, which is not within a protected area, that delivers long-term biodiversity conservation under equitable governance and management. OECMs can be governed by a variety of rights holders and actors including Indigenous peoples and local communities, government agencies, as well as sectoral actors, private organizations, and individuals.[10]
11 To what extent are waters beyond national jurisdiction protected? Although protected areas and OECMs now cover 18.01% within national waters, coverage in areas beyond national jurisdiction lags behind at 1.18%. [[11]]
12 What is the most diverse part of the earth? The ocean due to highly diverse marine and coastal ecosystems.[[12]]
13 How do habitats contribute to human wellbeing? Healthy marine ecosystems impact human beings' health and economies.[[13]]
Habitats such as coral reefs, seagrasses and mangroves generate sources of nutrition through fish, provide protection to coastal communities from storms, and contribute to local economies through tourism.[[14]]
Globally, more than half the income of poor rural households comes from nature, and healthy ocean ecosystems provide food, fuel, and other crucial benefits that help to alleviate poverty.[[15]]
Coastal habitats support subsistence aquaculture, fisheries and tourism, providing livelihoods and direct income to the local economy. [[16]]
Many coastal habitats, such as mangroves and coral reefs, are key tourist destinations and provide rich biodiversity that visitors can experience and enjoy, promoting people’s mental and physical well-being.[[17]]
14 Which is the international effort that intends to restore critical ecosystems? The UN Decade on Ecosystem Restoration is meant to restore the critical ecosystems of humans and biodiversity.[[18]]
15 What is the goal of the IUCN Red List? Helps to prioritize which species need conservation attention and protection more urgently.[[19]]
16 How many hectares of degraded land will the world need to restore?    At least one billion.[[20]]
17 What is the global picture of marine habitats status? Our ability to track the location and health of marine habitats over time varies across the world, making it challenging to provide an accurate and complete global picture. [[21]]
18 How large is the loss of live coral? 50% of live coral cover has been lost since the 1870s.[[22]]
19 What is the definition of habitat-forming species? Habitat-forming species are species such as seagrasses, corals and mangroves, which support diverse life by providing shelter or feeding grounds for other species and thereby play an important role in the functioning of an ecosystem.[[23]]
20 Which marine species have been assessed and how? While most warm-water coral, mangrove and seagrass species have been assessed by the IUCN Red List team, there are still many species of saltmarshes and cold-water corals that have not yet been assessed, with a “Not Evaluated” status.[[24]]
