Picture someone fishing, and a woman probably doesn't come to mind. Men are the face of fisheries work, even though women are its backbone in much of the world.
That's more than unfair. Excluding women overlooks half the workforce, and all the fish and shellfish they pull out of the water. Ignoring such a sizable chunk of fishing sets communities up to overexploit their resources, according to a 2006 study from the University of British Columbia. It's a recipe for overfishing and ocean depletion.
In the Tuvalu Islands, for example, a government initiative to restore edible sea snails failed because it only consulted men. Women also harvest the snails, and continued collecting them as usual, unknowingly trouncing the restoration effort.
Female fishers have deep knowledge of the seafoods they catch and the rhythms of the beaches where they work, often passed down matriarchal lines. They have strong incentives to manage natural resources sustainably, experts say, but first they need a seat at the table.

Pull Up a Chair
A glut of factors conspire to silence women in fisheries. Overt sexism is part of the problem, but sometimes exclusion is subtler. It can come down to definitions of fishing.
Around the world, men and women often catch seafood in gender-specific ways. Men tend to work in deeper water with specialized fishing gears, while women walk the shallows catching fish and shellfish at low tide, according to a 2013 study. Traditionally, men's work was considered fishing, the study said, while women were marginalized as collectors or gatherers.
Reasons for fishing also split along gendered lines. Women often work to feed their families, while men focus on lucrative species to sell, according to the Food and Agriculture Organization of the United Nations.
In societies where women manage the home and children, they may not have time to come to male-organized meetings, even if they are technically allowed, according to a study by economist Bina Agarwal at the University of Manchester, England. Social norms can also keep women quiet, in deference to men, if they do attend meetings.
In southwest Madagascar, for example, women walk the reef flats at low tide, collecting octopus with spears or rebar, while men dive for larger octopus and more valuable species in deeper water. Eighty-six percent of women harvest octopus, compared to 31 percent of men. Yet men, especially elders, dominate decision-making for the octopus fishery in village meetings, according to a 2013 study by the UK-based marine conservation group Blue Ventures.
"While some women do attend these meetings," authors Kame Westerman and Sophie Benbow of Blue Ventures wrote, "most do not have the time, desire, or support of their husbands and families."
Domestic demands pull women into fishing, and ironically, also lock them out of decision-making.
Those same household responsibilities also make women good stewards of their environment, Agarwal wrote, because they depend on natural resources day-in and day-out. In the rural forests of Gujarat, India, for example, women collect firewood daily for household chores and cooking. Men cut timber more sporadically. They can wait longer for felled trees to grow back.
It's women, villagers told Agarwal in 1995, who can't afford a depleted environment.

Lifting All Voices
Fisheries management is better when women are included. At the most basic level, that's because women are half the population. No decision reflects a community's reality without them.
Empowering projects are underway around the world.
In the Pacific Islands, Fiji's Ministry of Fisheries hosted a national forum last year to recognize and empower female fishers. A second meeting convened this May, where some women said they now raise concerns in village meetings.
In Sri Lanka, a project empowering women to restore badly-damaged mangrove habitats aims to bolster fisheries fringing the island. More than 7,000 women across 1,500 poor coastal villages trained to plant and tend mangrove saplings, in return for small loans at low interest to start their own businesses. The women keep an eye out for illegal clearing, which they report as part of the program. Empowering women as stewards of the mangroves aims to restore the forests, which provide critical nursery habitat for the island's subsistence fisheries, but have been largely cut down for development.
Efforts like these chip away at inequity, though progress toward fairness is slow. Women remain largely voiceless in fisheries in much of the world. Think how the oceans might change, what potential, if women were free to unleash theirs.

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.
Where Does the Deficiency Begin?<p>Nobody knows exactly how much vitamin D a person actually needs. The question of when a deficiency starts is correspondingly controversial. However, vitamin D is becoming increasingly popular.Not only is the pseudo-scientific literature on the "sun vitamin" experiencing an upswing, but the number of published studies has also increased enormously in recent years. For example, in 2019 <a href="https://academic.oup.com/edrv/article/40/4/1109/5126915" target="_blank">a study found that</a> Vitamin D is responsible for keeping the skeleton functional and is associated with cardiovascular diseases, type 2 diabetes and various types of cancer. <br></p>
An All-Rounder<p>Vitamin D levels in the body rise and fall according to sun exposure. If sufficient UV rays reach the skin, the body is able to produce the vitamin itself. However, the human body only derives an estimated 10 to 20 percent of its daily requirement from food.</p><p>The vitamin D that we synthesize from sunlight or food is not biologically active at first. Before the kidneys can produce the biologically active form of the vitamin, known as calcitriol, and release it into the blood, some metabolic processes must take place beforehand.</p><p>In addition, many organs have receptors to which the precursor of calcitriol binds. Further, this substance is also present in blood.</p><p>From this precursor, the organs then produce calcitriol themselves, which the body then uses for countless other processes in the body. This form of vitamin D thus regulates insulin secretion, inhibits tumor growth, and promotes the formation of red blood cells as well as the survival and activity of macrophages, which are important for the <a href="https://www.mdpi.com/2072-6643/5/7/2502/htm" target="_blank">immune system.</a></p>
Low Vitamin D, Severe COVID-19 Disease?<p>A research study carried out <a href="https://www.sciencedirect.com/science/article/pii/S2352364620300067?via%3Dihub" target="_blank">at the University of Hohenheim</a> has now established a link between vitamin D deficiency, certain previous diseases, and severe cases of COVID-19.</p><p>According to the study, "there is a lot of evidence that several non-communicable diseases (high blood pressure, diabetes, cardiovascular diseases, metabolic syndrome) are associated with low vitamin D plasma levels. These comorbidities, together with the often accompanying vitamin D deficiency, increase the risk of severe COVID-19 events."</p><p>"This statement is completely correct," said Martin Fassnacht, head of endocrinology at the University Hospital of Würzburg. However, he qualifies that it is a pure association, "i.e. a mere observation that these events occur together.</p><p>Dr. Fassnacht is very critical of the hype surrounding vitamin D, but not because he denies the vitamin serves important functions. However, studies on humans have not been able to show that vitamin D has the healing powers many often propagate.</p><p>Fassnacht says, "If you take a closer look, the hopes that the administration of vitamin D has a healing effect have not been confirmed so far."</p>
Association Versus Intervention Studies<p>Many studies on the vitamin are association or observational studies. "By definition, these studies cannot prove the causal relationship, but only point to mere correlations," said Fassnacht. The physician tries to illustrate this with an example:</p><p>"Imagine two groups of 80-year-olds. One group is spry, active and does sports. If you compare them with another group living in nursing homes, the difference in vitamin D levels will be dramatic. Life expectancy would also be extremely different."</p><p>But to try to explain the difference in fitness by vitamin D status alone is far too simplistic. "Vitamin D levels are a good measure of how sick someone is. But not more," says Fassnacht. </p><p>According to Fassnacht, none of the intervention studies carried out to date -- that specifically examined the effect of vitamin D on various diseases -- has been able to confirm the previous association and laboratory studies or the presumed positive effect of vitamin D.</p>
Further Research Is Needed<p>"If a coronavirus infection is suspected, it is therefore absolutely necessary to check the vitamin D status and quickly correct any possible deficit," said the recommendation of the paper published by the University of Hohenheim.</p><p>"Studies are underway to see whether vitamin D helps in COVID-19 infection, but I personally do not believe that this is really the case," says endocrinologist Fassnacht. Nevertheless, he says it is of course useful to carry out these studies.<br></p><p>"I don't want to rule out that there are actually subgroups of people who benefit from an additional vitamin D dose," he says. After all, this has been proven to be the case with a severe deficit.</p><p>In view of the study situation, Fassnacht does not think much of preventive, nationwide vitamin D substitutes. "My belief that the vitamin helps somewhere is very low. But, of course, I can be wrong."</p>
