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 episode of Pasha, Sarita Pillay, a PhD student at the University of the Witwatersrand, and Miriam Maina, a research associate at the University of Manchester, take us through their research on this lockdown toll.

The researchers got their information from multimedia diary entries made during the “level 5” lockdown. Their informants were people living in a variety of dwelling types, households and urban neighbourhoods. The entries recorded participants’ daily experiences, concerns and feelings.

Much of the anxiety people felt came from the fact that it was an unknown virus. People didn’t know how it would affect them. They also worried about people breaking lockdown regulations. The economic impact of the lockdown was a concern; food security was a big issue.

Feelings of isolation and frustration came from being alone. It didn’t help that people were separated from their daily routines.

The “Fourth Industrial Revolution” is a term coined in 2016 by German economist Klaus Schwab. It’s used to describe the technology revolution that the world is going through. But there is growing criticism, particularly in the global south, of how it’s framed. Many are questioning whether it should be considered a revolution at all.

The Fourth Industrial Revolution, according to one view, is a very simplistic narrative that advances a distinct political agenda. It is a kind of exploitation that is being sold as progress. The narrative is being advanced to achieve a specific economic outcome – at the expense of many people in the global south.

Many innovations are happening in the digital technological space. But do they reorganise production and social relations, or do they just entrench past forms of inequality?

Consider the case of the ride-hailing app Uber. It may sound like enticing work for drivers, but there’s more to it. Drivers may face bad working conditions, penalties and other challenges without the security of human resources behind them.

In this episode of Pasha, Ruth Castel-Branco, manager of the Future of Work(ers) research project at the University of the Witwatersrand, joins Nanjala Nyabola, a storyteller and political analyst, in taking us through the seductive idea of the Fourth Industrial Revolution.

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 there is also a risk of exposure to a range of threats. In one survey, about 50% of South African adolescents had been exposed to sexual content and 34% also reported exposure to violent content and hate speech.

Not all exposure is risky or damaging. But what can parents do to monitor their children’s use of the internet and protect them from potential harm?

The answer lies in finding the right balance between empowerment and protection. The internet is here to stay. Parents should engage with their children on the digital world. The quality of offline relationships and communication is the key to protecting children online.

In today’s episode of Pasha, Rachana Desai, a postdoctoral research fellow at the University of the Witwatersrand, offers some tips:

• Download the apps that your child frequently uses and understand why your child enjoys them.

• Ask your child to teach you how to use the technology they use. This is a great communication and interaction activity because children often like to teach their parents and it’s quite empowering for them.

• Friend your child on social media platforms – with boundaries. Do it in such a way that they still have their own space to express themselves.

• Talk to your child about their experiences online. Ask them open ended questions like whether there was anything that bothered them online. You want to get to know what’s going on without over-supervising and then having your child completely isolate you from the online world.

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 100 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 male killer whales, which researchers have named Port and Starboard, that arrived in the area. They have a signature way of tearing open their prey and they favour the nutrient-rich liver.

Though killer whales are known to hunt sharks far from shore elsewhere in the world, this was the first time the carcasses had washed up on a beach and become available for scientific study.

In today’s episode of Pasha, shark biologist and PhD candidate Alison Towner tells the unfolding story of the impact the killer whales are having on South Africa’s marine ecosystems. Great white sharks are fleeing to other parts of the coast and their absence affects other species like African penguins and Cape fur seals.

It’s a novel situation, with concerns for the tourism and conservation sectors – and no simple answers.

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 something strange while researching the conservation of carnivores. Looking at the skulls of lions and leopards to estimate the animals’ ages, she saw unnatural wear marks on the teeth of these big cats. This was caused by biting and pulling on snare wire to get free. What is more, many of the lions had old shotgun pellets embedded in their skulls. They had survived these injuries – but how many more animals had not?

Behind the threat to the lions and leopards are complex social and economic issues. People move to where there are opportunities to make a living – from wildlife tourism and associated economic activity, for example. This can bring them into conflict with animals. Some people set snares because they need food, not necessarily to catch carnivores. And they may fire shotguns to drive off predators, not to kill them.

It is vital to understand the complexities of these relationships. People who live close to parks need to receive the benefits of wildlife, as our guest explains in today’s episode of Pasha.

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 society groups are crucial to ensuring equity. They have the power to reach marginalised groups and can educate them about projects and about their rights. It is also important to make sure projects don’t become a political tool.

In today’s episode of Pasha, Gediminas Lesutis, a Marie Curie Fellow at the University of Amsterdam, talks about making massive infrastructure projects work for communities.

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 logging, poaching and fires. Or they can have an impact on the ecosystems of rivers, coasts or oceans.

Negative impacts can extend to communities through loss of livelihoods or exposure to natural hazards like flooding or erosion. One major criticism is that big development projects benefit wealthy people but don’t help poorer communities. They can widen huge socioeconomic disparities.

It is also important to make sure that projects consider how infrastructure might operate under a changing climate in the future. There might be much higher temperatures, higher variability in rainfall, and higher frequency of floods and droughts.

Today’s episode of Pasha takes a look at major infrastructure projects on the continent from a variety of perspectives. Our guests are biodiversity researcher Tobias Nyumba, climate change modeller Jessica Thorn, political analyst Gediminas Lesutis and geographer Declan Conway.

Kenya’s Standard Gauge Railway, which links Nairobi and Mombasa, East Africa’s largest port, was built to ease the pressure on the road network. Construction started in 2013 and was completed in 2017, with an extension in 2019. The line transports passengers as well as cargo. It makes the trip between the cities safer and shorter.

The project is also being promoted as a means to develop Kenya’s mining, oil, gas, energy and commercial agriculture sectors as well as the wider East African region. It aims to link Uganda, Rwanda, Burundi and South Sudan to the Indian Ocean trade routes to the east.

Projects like this are known as development corridors and have the potential to bring major socioeconomic benefits. Access to jobs and markets, efficient transport, cheaper food and opening up isolated areas are among them.

In today’s episode of Pasha we bring you the first episode in a series we’re running on development corridors. This episode looks at the positive aspects of such initiatives. Our guest this week is Jessica Thorn, a research associate with the Development Corridors Partnership between Tanzania, Kenya, China and the UK.

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 aggressive. If the call was one they recognised, they were less inclined to be aggressive.

One way hippos show aggression is to spray dung.

The meaning of hippo sounds is useful to know for conservation efforts. Hippos and humans sometimes come into conflict and need to be moved for their own survival. Before relocating them, conservation managers could play them the sounds of the hippos they will be meeting in their new location, to familiarise them.

In this episode of Pasha, Nicolas Mathevon, professor in animal behaviour and bioacoustics at the University of Saint-Etienne, and Paulo Fonseca, professor in acoustic communication at the University of Lisbon, take us through their experiences of listening to hippos in Mozambique.

The researchers would like to thank the Maputo special reserve for allowing them to do the research on the property.

A few years ago the South African city of Cape Town was close to reaching “day zero” – the day the taps would run dry as a result of a serious drought. Households had to restrict their water usage, water tariffs increased, and businesses had to rethink how they used water. But the situation affected people unequally. Households experienced it in different ways. The poor and vulnerable suffered the most.

With the changing climate, problems like these aren’t going anywhere. Water scarcity, higher temperatures and changing rainfall patterns will become more common, so finding ways to adapt is important. And in a city where inequality and financial pressures are deep and complex, adaptive change will take time.

It also takes information. For city planners and decision makers, data is essential – but not just quantitative data. They need to engage with people to understand how they experience issues like water scarcity.

In today’s episode of Pasha, two researchers discuss their work on inequality in water and describe a project that brought city authorities and community members together. Gina Ziervogel is in the Department of Environmental and Geographical Science and Johan Enqvist is with the African Climate and Development Initiative, both at the University of Cape Town.

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 everyone can equally exercise that right. Some people are more connected than others.

Radio and television are also useful technologies in widening access to education but they mostly require electricity, which isn’t universally available either.

In today’s episode of Pasha, vice-chancellor and principal Tawana Kupe shares what the University of Pretoria in South Africa did to make online learning possible for all its students. He calls for public-private partnerships to develop internet infrastructure so that everybody can have access. And he makes the case for an internet-empowered education system at all levels.
