Africa Science Focus

Sub-Saharan Africa faces significant food security challenges, exacerbated by climate change and conflict. In this episode of Africa Science Focus, we explore the potential of hydroponic farming. This type of farming uses nutrient-rich solutions instead of soil—allowing for controlled and sustainable food production. Our reporter, Abdulkareem Mojeed, speaks to farmers and researchers who share their experiences and insights on harnessing hydroponics to improve crop yields. Adeniyi Olayanju, a Nigerian professor of sustainable agricultural mechanisation, says hydroponic farming can mitigate the effects of herder invasions. Earnest Larmie, a Ghanaian farmer, says the climate-smart method enables him to farm all year round, despite weather fluctuations. Nigerian farmer Modupe Olafusi explains how she uses fish water as compost for her hydroponic farming system. ------------------------------------------------------------------------------------------------------------ This piece was produced by SciDev.Net’s Sub-Saharan Africa English desk.

The Nigerian government's approval earlier this year of transgenic insect-resistant and drought-tolerant maize varieties, also known as TELA maize, has sparked intense debate among farmers, scientists, and the general public. In this episode of Africa Science Focus, reporter Jayne Augoye hears out the diverse perspectives on the introduction of TELA maize, a genetically modified (GM) crop, which proponents say will contribute to food and nutrition security. Samuel Agele, professor and researcher in plant ecophysiology at the Federal University of Technology, Akure, emphasised the need for public education and the regulation of genetically modified crops in Nigeria, amid concerns over possible health and environmental impacts. Ijeoma Akaogu, a plant breeder and geneticist and programme officer at the African Agricultural Technology Foundation - implementing partner of the TELA maize project in Nigeria - says the engineered crops have increased resistance to pests and diseases. However, farmers Anthony Musa and Olusola Sowemimo have differing views on the benefits of GM crops. ------------------------------------------------- Africa Science Focus is produced by SciDev.Net and distributed in association with your local radio station.

Citizen science educates the public about science and enhances research for evidence-driven policies In this episode of Africa Science Focus, our reporter Michael Kaloki speaks with African scientists who discuss the important role citizen science plays in scientific research. Peter Elias, a geography professor in Nigeria, says communities use storytelling and folklore to document their experiences, providing valuable supplementary knowledge to scientific research. Jaqueline Goldin, a professor of anthropology in South Africa, says a major challenge she faced in her citizen science project was gaining the trust of farmers, but she successfully addressed this by using social dialogue and partnering with education authorities. And Doris Wangari, senior program officer at the Science for Africa Foundation, says her team engages citizens in reviewing proposals for innovative products that benefit the community. ------------------------------------------------------------------------------------------------------------ This podcast was supported by the Science Granting Councils Initiative which aims to strengthen the institutional capacities of 18 public science funding agencies in Sub-Saharan Africa.

The dapivirine vaginal ring holds promise in the fight against HIV. But for the young women in Africa who need it most, access remains a major challenge. Women aged 15 to 24 are disproportionately vulnerable to HIV infection due to a complex web of factors, including social, cultural, and economic forces. The silicone ring reduces their risk of infection by continually releasing the antiretroviral dapivirine into the vagina. In this episode of Africa Science Focus, reporter Bunmi Yekini looks at issues such as access to the ring and the impact the ring has in countries that have approved its use. Akhona Gxarisa, a research participant in the dapivirine study in South Africa, shares her experience of using the ring with her partner and advocates for greater availability of the product. Patriciah Jeckonia, programme manager, policy and partnerships, at LVCT health, a non-governmental organisation in Kenya, says that the ring presents “an opportunity for women to prevent HIV and choose what works for them when they are at risk”. In South Africa, the HIV prevention project FastPrEP is raising awareness of prevention methods among South African youths. Marketing and communications coordinator Mbali Jonas explains how this is being done, using mobile clinics and courier services. Nigeria is one country that is yet to introduce the ring. Oliver Ezechi, director of research at the Nigerian Institute of Medical Research and professor of maternal, reproductive and child health at Lead City University, in Nigeria, explains why. ------------------------------------------------------------------------------------------------------------ Do you have any comments, questions or feedback about our podcast episodes?

Effective policymaking in Africa requires collaboration between scientists and policymakers. But, despite the potential for science to drive sustainable development, the relationship between these two groups can be underwhelming. In this episode of Africa Science Focus, scientists highlight the need for scientists and policymakers to work together to create evidence-based policies to solve problems and share successful examples of scientific advisory. ------------------------------------------------------------------------------------------------------------ This podcast was supported by the Science Granting Councils Initiative which aims to strengthen the institutional capacities of 18 public science funding agencies in Sub-Saharan Africa.

After Africa achieved wild poliovirus-free status in 2020, the region faced a setback with outbreaks recurring in Mozambique and Malawi in 2022. However, a swift global response by countries and health organisations, including large-scale vaccination campaigns reaching 50 million children across five nations, culminated in a recommendation this month by the independent Poliovirus Outbreak Response Assessment (OBRA) to declare the end of the wild poliovirus type 1 outbreaks in Southern Africa. In this episode of Africa Science Focus, reporter Justice Baidoo speaks to public health experts to uncover the strategies Southern African countries adopted to fight the disease.

Growing more local seeds in Africa can solve the region’s food insecurity and climate problems. Local crops and seeds are often neglected in Africa, despite their nutritional and environmental benefits, research has shown. In this episode of Africa Science Focus, Method Gundidza, director of the EarthLore Foundation, explains to reporter Elna Schütz the legacy of colonialism on these native species. Siphiwe Sithole, a farmer and managing director at African Marmalade, an agribusiness that specialises in African crops, highlights the significance of indigenous seeds on the continent. Using research, Albert Modi, executive dean of the Faculty of Natural Sciences at Walter Sisulu University, South Africa, assesses the level of use of local seeds in Africa. Meanwhile, Mariam Mayet, executive director of the African Centre of Biodiversity indicates ways African farmers can increase the use of indigenous seeds.
