In Kenya, where Moses Ngoze teaches entrepreneurship and management at Masinde Muliro University in Kakamega, micro, small and medium enterprises provide 75% of jobs and more than 80% of the country’s gross domestic product. Typically these organizations employ between one and 100 people and include subsistence farming, hospitality and artisan businesses, mostly operating in a jua kali environment, a Swahili term meaning “hot sun,” he says.Ngoze's research explores how the enterprises can help achieve full employment and sustained (and sustainable) economic growth by 2030, captured in Sustainable Development Goal 8, one of 17 agreed by the United Nations in 2015.He tells the How to Save Humanity in 17 Goals podcast that African economies and employment ambitions need more than multinational employers moving there. These firms only employ 10% of the world’s workforce, he says.Infrastructure improvements are also needed, Ngoze adds, alongside more reliable energy, stronger internet connectivity, and tax breaks for business. Government funding for university-based centres of enterprise development are also a priority.The podcast series profiles scientists whose work addresses one or more of the SDGs. Episodes 7-12 are produced in partnership with Nature Water, and introduced by Fabio Pulizzi, its chief editor.

Julien Harou’s career started in geology in his current role as a water management and infrastructure researcher now straddles economics and engineering, with a particular focus on using artificial intelligence (AI) to measure Ghana’s future energy needs. Harou is relatively upbeat about progress so far towards achieving sustainable and reliable energy for all by 2030, the seventh of 17 Sustainable Development Goals (SDGs) agreed by the United Nations in 2015. He points out that from 2015 to 2021, the portion of the global population with access to electricity increased from 87% to 91%, and last year about 30% came from renewable sources. Harou’s research at the University of Manchester, UK, incorporates computer modeling and artificial intelligence design algorithms to balance Ghana’s long term renewable energy and infrastructure needs. But AI also helps to address the environmental and human health impacts. For example, Ghana’s Volta River was dammed in the 1960s to create the Akosombo dam. But its arrival depleted fish stocks and increased weed and algae growth, providing habitat for vectors of waterborne diseases. It’s all about compromise, he tells the seventh episode of How to Save Humanity in 17 Goals, a podcast series that profiles scientists whose work addresses one or more of the SDGs.Episodes 7-12 are produced in partnership with Nature Water, and introduced by Fabio Pullizi, its chief editor.

María Teresa Dova describes how an early career move to CERN as the first Latin American scientist to join Europe’s organisation for nuclear research ultimately benefited both her but also the researchers she now works with back home in Argentina.The move to Geneva, Switzerland, where CERN is based, required Dova to pivot from condensed matter physics, the subject of her PhD at the University of La Plata, Argentina, which she gained in 1988. But any misgivings about the move to Europe and switching to a new field were quickly banished by her excitement at working on the L3 Large Electron Positron Collider project, she tells Julie Gould. Dova returned to Argentina two-and-a-half years later, launching the experimental high energy group at La Plata and driving other important collaborations, including the inclusion of Argentina in CERN’s ATLAS particle detector collaboration. She describes how it happened.

A 2021 report by the UNESCO International Institute for Higher Education in Latin America and the Caribbean revealed that only 18% of public universities in the region had female rectors. Vanessa Gottifredi, a biologist and president of Argentina’s Leloir Institute Foundation, a research institute based in Buenos Aires, says this paucity of visible role models for female scientists in the region means that damaging stereotypes are perpetuated.A female, she says, will not be judged harshly for staying at home to handle a family emergency, but will be for being pushy at work, unlike male colleagues. “Women need to hear that they are good, more than men do, because they tend to convince themselves they're not good enough,” she adds.In the penultimate episode of this six-part podcast series about female scientists in Latin America, Gottifredi, who worked abroad for 11 years before returning to Argentina, tells Julie Gould how she aims to empower female colleagues, based on what she witnessed elsewhere.

Fernanda Staniscuaski earned her PhD aged 27. Five years later she had a child. But in common with many scientist mothers, Staniscuaski, a biologist at Brazil’s Federal University of Rio Grande do Sul, saw funding and other career opportunities diminish as she combined motherhood with her professional life. “Of course I did not have as much time as I was used to have. And everything impacted my productivity,” she tells Julie Gould.The Brazilian biologist founded the Parent in Science advocacy movement after talking with other scientist parents. In the fourth episode of this six-part podcast series about Latin American women in science, Staniscuaski lists the movement’s achievements so far, and the challenges that lie ahead.In 2021 Parent in Science won the science outreach category in the Nature Inspiring Women in Science awards, in partnership with the Estée Lauder Companies.

Paleontologists Ana Valenzuela-Toro and Mariana Viglino outline some of the challenges shared by researchers across Latin America. These include funding, language barriers, journal publication fees and conference travel costs. But the two women then list some of the extra burdens faced by female researchers who live and work there, many of which will resonate with female colleagues based elsewhere. “When you are in a room sharing a scientific idea or project, nobody listens to you. Then another person, usually a male researcher, says what you said,” says Valenzuela-Toro, who is based in Caldero, Chile. Mariana Viglino, a Puerto Madryn-based researcher at CONICET, an Argentine government science agency, says the election of far-right governments inevitably results in science funding cuts. “And that means many people having their careers cut. Many research projects that are not going to be able to continue,” she warns.“It makes me feel really hopeless, and really burnt out, and really sad. I really don’t even know how to put it into words. You want to give back to the government who has invested in you. You want to give back to society. You just feel like they are just pushing you out.”

In 2013 physicist Carolina Brito co-launched Meninas na Ciência (Girls in Science), a program based at Brazil’s Federal University of Rio Grande de Sul.The program exposes girls to university life, including lab visits and meetings with female academics. “There are several girls who have never met someone who has been to university,” says Brita. “It’s beyond a gender problem.”Jessica Germann was one of them. The 19-year-old is about to start an undergraduate physics degree. She tells Julie Gould how writing a school essay about particle physics and a fascination for YouTube science videos helped in her career choices.This episode is the second episode in a six-part Working Scientist podcast series about Latin American women in science.

In her role as Vice Rector for research partnerships and collaboration at the University of the Valley in Guatemala City, Monica Stein works to strengthen science and technology ecosystems in the Central American country and across the wider region.To mark International Women's Day on 8 March, Stein outlines the steps needed to attract girls into science careers. Access to higher education needs to widen, she argues, alongside more robust legal and regulatory frameworks to make research careers more diverse.“We need to inspire other women, we need to mentor other women, we need to be available for conversations,” she says. “We need to tell them it’s okay to say no to a project, because you’re pregnant, just giving birth, or your child is young, which is something that is so common here in Guatemala.”This episode is the first episode in a six-part Working Scientist podcast series about Latin American women in science.

Laure Sione’s postdoctoral research at Imperial College London addresses the sixth of the 17 United Nations SDGs, but, she argues, sanitation also plays a huge role in gender equality (SDG 5) and good health and well being (SDG 3) targets.Sione’s PhD research focused on water management challenges in Kathmandu, but she now focuses on Sub-Saharan Africa and the problems caused by open defecation and excrement-filled pit latrines that are sited too close to the water table, risking contamination.A third option is toilets layered with Tiger Worms. A key advantage is that these take longer to fill up as the worms quickly degrade faeces, but one barrier is getting people to use them in the first place. “It’s like, it’s a gross thing, and they don’t want to think about it. But I think the benefits quickly take over,” she says.Each episode of How to Save Humanity in 17 Goals, a Working Scientist podcast series from Nature Careers, features researchers whose work addresses one or more the targets. The first six episodes are produced in partnership with Nature Food, and introduced by Juliana Gil, its chief editor.
