shutterstock When SARS-CoV-2 emerged in South Africa, the country took measures to restrict people’s movements and activities, to slow the spread of infections. There were various levels of restrictions, the most severe being in place in March and April 2020. During this “hard lockdown”, many people in South Africa really struggled. Not only did they have financial difficulties but the lockdown took an emotional and mental toll. The common themes, no matter where people lived, were feelings of anxiety, frustration and isolation. And as lockdown went on, those feelings got worse. In today’s epi ..read more

GettyImages Young children and adolescents are becoming hyper connected. They are using digital technologies as a platform for learning, connection and socialisation on a global scale. The COVID pandemic meant that kids were moving online for many of their daily activities and spending more time online. In South Africa, children generally access the internet at home much more frequently than at school, and most commonly using a smartphone. Their main online activity is use of social media. Connecting online has the potential to reduce inequalities and barriers to education and services. But th ..read more

shutterstock Great white sharks have long been at the top of the food chain in parts of South Africa’s oceans. In their peak winter hunting months, around 1,000 great white sharks a day could be observed off the coast of the Western Cape province. But in 2017, great white shark carcasses began to wash up on beaches at Gansbaai, one of the main sites where the species usually gathered. Some were missing their livers. And the numbers of great white sharks in Gansbaai started to drop. In fact, they just vanished for up to a year at a time. What was the cause? The culprits appear to be a pair of m ..read more

GettyImages Wildlife and people are coming into more and more conflict across Africa as human populations expand. Habitat loss and fragmentation of animal populations are causing declines in species. In Zambia, the Luangwa Valley and Kafue are two important wildlife areas. Both support populations of lion and leopard which are genetically linked to populations in neighbouring countries. They have great conservation value and are crucial for Zambia’s tourism industry too. It was here that Paula White, director of the Zambia Lion Project at the University of California in the US, noticed somethi ..read more

GettyImages Big infrastructure projects should be based on the needs of people and communities. Often, they are criticised for benefiting the wealthy only. These projects reflect specific agendas of political and economic elites who are able to advance their interests through the developments. They interplay with existing inequalities and almost inevitably have highly uneven effects. An example is Kenya’s Standard Gauge Railway, a massive infrastructure project that connects the port city of Mombasa to the capital, Nairobi. So how can these projects be made beneficial to more people? Civil soc ..read more

There are some major development projects in progress on the continent. They include the Standard Gauge Railway in Kenya and irrigation and hydropower projects in Tanzania’s Rufiji Basin. Projects like these have potential to change people’s lives for good. But they also come with risks. Some big projects damage environments by disturbing the habitats of wildlife like lions and elephants. In Kenya the rail project has displaced these animals so that they come into conflict with people. Construction can also bring in and spread invasive species. Some projects can lead to an increase in illegal ..read more

shutterstock Hippos are very vocal animals, exchanging signals like the “wheeze honk”. But not much is known about what these sounds mean. Two researchers found themselves thinking about this in Mozambique – where they were initially studying crocodiles. Hippos are quite territorial and aggressive – and fast-moving. So the researchers kept a fair distance away as they conducted their experiment. They recorded hippo noises and played them back to the animals, watching to see how the hippos behaved. If the call came from an unknown hippo in a different social group, the response appeared to be a ..read more

The COVID-19 pandemic disrupted normal contact learning in education systems worldwide. Technology became an essential tool for learning and it has great potential beyond the pandemic. For one thing, it enables more interactivity than some old styles of teaching. But there are a number of barriers to using technology more widely in education. Users need data, a device and a learning management system. They need training in the skills to learn and teach online, and support for troubleshooting. Internet access may be seen as a human right, but Africa’s digital divide means that in reality not e ..read more

Getty Images The lakes of the Democratic Republic of Congo (DRC) play a big part in people’s lives – socially, politically and economically. But lake fishing communities find themselves at the intersection of geography, war and authority, as rebel groups and conservation managers also claim spaces and resources. By some estimates there are over 70 armed groups in the country, led by warlords, traditional tribal elders, village heads and politically motivated resistance fighters. Lake Edward is also a conservation area and park managers try to limit the illegal fishing there. This creates conf ..read more

shutterstock Vaccine hesitancy is the delay in acceptance or refusal of vaccination, where vaccination services are available. It’s a diverse phenomenon: people may have different degrees of hesitancy, and may refuse some vaccines but agree to others. In 2019, the World Health Organization identified vaccine hesitancy as one of the 10 greatest threats to global health. It is very worrying because it poses significant risks not only to the hesitant individual but also to the wider community. Vaccine hesitancy has resulted in outbreaks of vaccine preventable diseases. For example there were meas ..read more
