human health and wellbeing are connected. The results suggest that marine protected areas can be good for both planet and people. These areas of the ocean are legally recognised by governments as being important for <a href="https://theconversation.com/most-marine-protection-measures-are-not-working-a-new-more-flexible-approach-is-needed-232753">marine conservation</a>. They are protected by putting limits on human activity within and around them. </p> <p>Once a government declares a marine protected area, you usually can’t live in it, fish, build a beach resort, start a fish farm or drill for oil in it. The rules vary from place to place, but the idea is to allow nature to flourish by limiting human activity as much as possible. </p> <p>With plans to expand ocean protection under the UN-endorsed biodiversity plan’s <a href="https://www.un.org/en/delegate/un-delegates-reach-historic-agreement-marine-biodiversity">“30x30” target</a> (which aims to protect 30% of the world’s land and oceans by 2030), it’s important to know how this will affect people as well as nature.</p> <p>The study was conducted by the conservation charity World Wide Fund for Nature, Harvard Institute of Public Health and Duke University’s marine laboratory.

Only three out of the 237 studies reviewed had studied how creating marine protected areas affected the diets of people living around them. Only one study, in the Philippines, made the link between diets and health outcomes, because, when access to fish in diets improved due to marine conservation, there were fewer stunted children from surrounding communities.</p> <h2>Plenty more nutrients in the sea?</h2> <p>Our continents and islands are surrounded by seas, lakes, rivers and floodplains that are populated by edible plants and animals rich in vitamins, minerals and fatty acids. These micronutrients from aquatic foods are <a href="https://www.nature.com/articles/s41586-021-03917-1">highly bioavailable</a> (easily absorbed by the body). If sustainably harvested and made available to nutritionally vulnerable people, they could prevent malnutrition <a href="https://www.nature.com/articles/s41586-019-1592-6">among millions of coastal people</a>.</p> <p>The new report has quantified the micronutrient contributions to human diets from the aquatic foods that flourish when marine protected areas are set up. It combines data on the nutrient composition of all the aquatic foods harvested in and around marine protected areas, with fish catch data from the surrounding areas.</p> <p>The existing marine protected area network supports <a href="https://www.cell.com/one-earth/fulltext/S2590-3322(24)00480-9">14% of the global supply</a> of six key micronutrients from marine fishing. This is achieved by protecting only 8% of the world’s oceans. By allowing marine life to grow abundantly inside protected areas, nearby fish populations are replenished. So, by conserving marine wildlife, protected areas help to sustain fish and shellfish stocks. </p> <p>That means bigger catches, more income from fishing or tourism, and more food. More nutrients means better health. This applies both to marine protected areas with a strict no-take zone, where any form of fishing is banned, and those that allow regulated fishing.</p> <p>As populations increase, demand for aquatic food rises. Wild harvests are being supplemented by aquaculture and mariculture – these are freshwater and marine equivalents to growing crops and livestock on land. Over half of the aquatic foods consumed directly by humans are now produced from aquaculture, much of it in inland waters rather <a href="https://www.nature.com/articles/s41586-021-04331-3">than the sea</a>. </p> <p>But in many countries, particularly island and coastal nations in the developing world, harvesting wild food from marine ecosystems remains crucial to nourishing the over 3 billion people who get more than 15% of their animal source proteins from <a href="https://bluefood.earth">aquatic foods</a>.</p> <figure class="align-right zoomable"> <a href="https://images.theconversation.com/files/629067/original/file-20241030-21-f91ofp.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><div class="placeholder-container" style="--aspect-ratio-percent:67.08860759493672%;--background-color:#4d3427"><img alt="sushi on a plate, colourful with orange salmon fish" class="lazyload" data-src="https://images.theconversation.com/files/629067/original/file-20241030-21-f91ofp.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=237&fit=clip" data-srcset="https://images.theconversation.com/files/629067/original/file-20241030-21-f91ofp.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=402&fit=crop&dpr=1 600w, https://images.theconversation.com/files/629067/original/file-20241030-21-f91ofp.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=402&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/629067/original/file-20241030-21-f91ofp.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=402&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/629067/original/file-20241030-21-f91ofp.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=505&fit=crop&dpr=1 754w, https://images.theconversation.com/files/629067/original/file-20241030-21-f91ofp.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=505&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/629067/original/file-20241030-21-f91ofp.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=505&fit=crop&dpr=3 2262w" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px"></div></a> <figcaption> <span class="caption">Seafood is a rich source of vitamins, minerals and fatty acids.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-photo/sushi-93406288">WhiteYura/Shutterstock</a>, <a class="license" href="http://creativecommons.org/licenses/by-nc-nd/4.0/">CC BY-NC-ND</a></span> </figcaption> </figure> <p>Despite their potential to address global micronutrient nutrition, aquatic foods have, until recently, been underrepresented in policies and programmes to end <a href="https://link.springer.com/article/10.1007/s13280-020-01451-4">hunger and malnutrition</a>.

It’s not clear who benefits when income from tourism and fishing increases, or whether increased catches get to those that need it most. In the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0308597X21003845">Maldives</a> for example, more than 80% of reef fish are consumed by tourists, not locals. </p> <p>Trying to solve malnutrition with marine protected areas is going to be challenging. Many marine protected areas are <a href="https://www.cell.com/one-earth/fulltext/S2590-3322%2824%2900364-6">not effectively managed</a>. By contrast, <a href="https://www.fao.org/newsroom/detail/fao-report-global-fisheries-and-aquaculture-production-reaches-a-new-record-high/en#">77% of catches</a> from the world’s fisheries come from stocks that are managed sustainably, though they have little room for expansion to meet rising demand.
