This month’s podcast explores how a data revolution can help push governments to be more accountable to meeting the Millennium Development Goals. Ndeye Fatu-Sesay of the Millenium Challenge Coordinating Unit talks about progress in Sierra Leone, and how more can be done to listen to the voices of the country’s citizens.

Next, we travel to Ethiopia for the second meeting of the Africa-EU Energy Partnership. The AEEP is struggling to meet their clean energy goals by 2020, according to Jacob Waslander, head of the Climate Change and Energy Division at the Ministry of Foreign Affairs in the Netherlands. The solution must incorporate small-scale local energy to reach more Africans, according to Gianluca Cescon, who builds microgrids in Tanzania and is head of country operations at Devergy.

Then we hear from Anne Radl of the Humanitarian Centre about a unique event to tackle development challenges. The Innovation and Development Hackathon will team students, professionals and NGOs to develop projects that will improve transparency along the global food supply chain. Past innovations include the SIM-Prints mobile biometric scanner to help Medic Mobile keep track of patient medical records.

Finally, former director of field operations at the United Nations Food and Agriculture Organization, Andrew MacMillan, pays us a visit. He talks about a school building project in one of Kenya’s poorest districts that is also helping to build community resilience to health and farming crises. He calls for new food management programmes to curb obesity and eradicate hunger.

In this month’s programme, we examine what’s on the radar for science and development in 2015.

First, we take stock of the global response to the escalating danger of climate change, with a report from the UN’s latest climate summit in Lima, Peru. We reflect on the outcome of the conference, on what ongoing efforts will be taking place over coming months and on the major milestone for climate negotiations: the next UN climate summit in Paris, France, at the end of the year.

To mark the start of the UN year of light and light-based technologies, we open our series on light technology for development by travelling to Tanzania to discover how solar power and mobile phones can fulfil basic energy needs and support grass-roots entrepreneurship.

Finally, as the world takes stock of what has been achieved within the Millennium Development Goals initiative, we discuss solutions to accelerate progress towards meeting the Sustainable Development Goals that will succeed them. We talk to Peter Singer, a proponent of science and innovation in global health, who explains how to encourage the scaling up of innovation success, and how to measure it.

In this month’s podcast, we follow up on June’s reflection around internet access by reviewing a new device, called BRCK, that can bring connectivity to rural areas where electricity is scarce. Albeit remaining unaffordable to many, BRCK could be a step towards the ultimate goal of enabling everyone, everywhere to connect to the net.

We hear about how, after more than three decades of rapid growth, China is entering a new phase of development, in which it aims to promote economic growth while also slowing the rise in its greenhouse gas emissions. We discuss the new model of sustainable growth with policy analyst Fergus Green, coauthor of a paper on China’s growth and emissions.

Although controversial, nuclear power could be crucial to China’s low-carbon growth. And nuclear science offers other benefits. We discover how two decades of watching out for hidden nuclear explosions has created a stockpile of data that scientists across the world can use even when their research has nothing to do with nuclear science. 

Finally, we ask why insurance schemes are in the spotlight as part of the post-2015 agenda for equitable global development. Political economist and human rights analyst Ana Gonzalez Pelaez explains that insurance for the poorest is crucial for rebuilding communities after natural disasters. She argues that it not only facilitates reconstruction, but it can also help reduce risk and enhance preparedness before disaster strikes.

Livestock farming is the largest land use system on Earth. It uses 30 per cent of the world’s ice-free surface and sustains about 1.3 billion people. 
But livestock is also responsible for 14.5 per cent of greenhouse gas emissions caused by humans, of which cattle produce 65 per cent. Better cattle management is vital to improve productivity while reducing emissions.

In Kenya, researchers are working with smallholder farmers to determine the impact of this form of land use and improve cattle and crop management. We discover how better practices can reduce farmers’ carbon footprint. 

Next in the podcast, we hear an update on earthquake stricken Nepal, where the monsoon is hindering reconstruction efforts and putting people and buildings at risk in a nation where thousands are now homeless.

Climate change can increase the severity of extreme weather events that worsen the impacts of earthquakes and other natural disasters. Communities must adopt adaptation strategies to survive. But humans are not alone in the struggle: plants and animals have to cope too. We hear about adaptation in the natural world and learn why changing biodiversity patterns may ultimately also affect humans.

Finally, we shed light on a controversial climate change response set of technologies. So-called negative emission technologies aim to suck carbon dioxide out of the atmosphere and store it underground. But they come with a set of hurdles, from high costs to different environmental hazards. Economists and analysts are calling for a global deployment of such technologies, but many believe that a stronger push on mitigation offers a safer way to curb emissions.

Of the 16 million people worldwide who are injection drug users, 3 million are HIV positive and 10 million have Hepatitis C. In this month’s podcast we first look at an effective approach to reducing harm from drug abuse. Earlier this year, the city of Vancouver in Canada hosted a global conference on HIV to discuss options for treatment and infection prevention. Vancouver is one of the first cities in North America to trial a new approach to drug harm reduction. The strategy — of providing heroin addicts with a safe space and sterile needles to inject — reduces the likelihood of people contracting viruses such as HIV or hepatitis C through sharing needles. This approach isn’t new. But practical examples of this measure are still rare. The system is working in Vancouver, but could it be exported to the developing world? 

We then travel to Kenya to learn about simple rainwater harvesting systems called sand dams that are helping nomadic farmers adapt to climate change. As the weather in already arid regions becomes more erratic, the nomadic pastoralists who live there are struggling to cope. The arid Isiolo County in central Kenya was chosen to pilot new technologies designed to tackle water shortages. One of these technologies was sand dams, which provide clean water both for domestic and farming use. The project was so successful it is being expanded to four other counties, covering 29 per cent of the country. 

From tiny rainwater harvesting systems to huge hydropower structures, we next look at the mega dams that are mushrooming across Africa, and discover that projects currently in the pipeline could cause 78,000 extra malaria infections each year. This may be just a small proportion of the continent’s total malaria burden, but it is one that could easily be avoided by including prevention in the risk assessment plans of every new hydropower plant.

Finally, we explore wildfires and discover how an online tool hopes to improve their management. Wildfires are not just a threat. They are also a natural event in many arid regions, helping to regulate ecosystems. They occur during the dry season in many parts of the world, from the United States to South Africa. Here in particular, about 70 per cent of the land is naturally adapted to fire and needs fire to maintain its ecological balance. 

But fire can be dangerous for humans and their activities, and so must be managed. Lee Annamalai, a researcher at the Council for Scientific and Industrial Research in South Africa, talks about AFIS, an online tool that merges data from satellites with crowdsourced information to detect wildfires and help speed up the emergency response.

In this audio interview, South African Gloria Hlongwane talks about her research into using graphene to create a cheap, portable DNA detector.

Once she has completed her PhD at the University of the Witwatersrand, Hlongwane aims to move into business — something she says is more challenging because of a lack of connections between industry and science in today’s South Africa. She plans to become an intermediary between the two sectors.

Hlongwane’s PhD is being funded by the Regional Initiative in Science and Education (RISE).

The interview was recorded at the Planet Earth Institute’s Unconference earlier this year, in London, United Kingdom. 

This is part of the Africa’s PhD Renaissance series funded by the Carnegie Corporation of New York.

For most people a doctor is probably the first port of call when it comes to informFor most people a doctor is probably the first port of call when it comes to information about how to keep in good health. Still, much guidance gets broadcast by the media, and in developing countries the radio remains a major source of public health advice.

But just how much is the impact of the mass media? Do they save lives, and at what cost? 

For five years, the West African country of Burkina Faso has been a testing ground for a media campaign designed to answer these elusive questions using the gold standard of scientific study, a cluster-randomised clinical trial. The trial targeted child mortality, treating the media as any other health intervention and measuring lives saved after three years of continuous radio programming with information about behaviours that can prevent disease, such as taking a child to a health centre.

SciDev.Net spoke to the project’s leader, Roy Head, CEO of the social enterprise Development Media International. Head explains the rationale behind the study and offers a preview of the results, due to be published later this year. 

The interview was recorded on 23 February at the 2017 ISNTD Festival organised by the International Society of Neglected Tropical Diseases in London, UK.

Dans ce numéro de Santé, Science et Développement, nous nous rendons au Cameroun.
Les glissements de terrain survenus fin octobre à Bafoussam, dans la province de l’Ouest, ont fait des dizaines de morts…
Ces glissements de terrain étaient consécutifs à de fortes pluies, qui se sont abattues ces dernières semaines sur la région.
Ce type de phénomènes se multiplient du reste sur le continent.
On se souvient qu’au Niger, le débordement de la rivière Komadougou a détruit des rizières et fait 42 morts.
Récemment, on a dénombré 28 morts au Ghana et 286 maisons rasées en raison de pluies torrentielles. Au Soudan du Sud, bien qu’on soit au début de la saison sèche, les pluies, qui ont déjà détruit 20.000 tonnes de riz, devraient encore durer plusieurs semaines. 
Pour certains scientifiques, il s’agit, simplement de quelques manifestations du changement climatique.
