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 how the Ebola emergency has led to new forms of humanitarian response. One is the use of music to educate people about safety practices using simple language. We interviewed Carlos Chirinos, a visiting professor at New York University, United States, where he specialises in radio and development. He says that local West African communities tend to trust musicians more than doctors as sources of information, making them powerful allies when spreading public health messages.

We learn how biobanks, which store biological samples, are helping Africa foster local research capacity and what challenges the collection and management of genetic material present.
 
Shivaji Pandey, a special advisor to the UN Food and Agriculture Organization, shares his views on the organisation’s 2014 report on food insecurity. It highlights significant progress towards the global eradication of hunger, but points to remaining political challenges.
 
We also find out about ‘flying donkeys’: cargo drones that, within a couple of years, could be delivering blood to remote parts of Uganda. There are hopes that these drones will transform transport in Africa by opening up rural areas and reducing urban congestion.
 
Finally, opinion and special features editor Anita Makri tells us about SciDev.Net’s upcoming ‘Spotlight’ on urban sustainable development.

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.

They are the world’s most vulnerable people. Often living in informal settlements and speaking only local languages, they are difficult to count and conventional surveys don’t capture their opinions, needs or even their presence.

A recent report by the Overseas Development Institute, in the United Kingdom, looks at the issue and tries to explain why the poorest are often left out of the official statistics that inform policymaking. Reporter Kevin Pollock speaks to one of the report’s authors to learn more.

If millions are missing from the global count, too many are also left offline, without access to the internet services that people in richer countries take for granted. We spoke with communication system expert Jon Crowcroft about the idea of moving away from the current trend of building a few big data centres that send and receive many people’s information, and instead decentralise the internet by establishing a larger number of more localised servers. Crowcroft argues that internet access should be considered a human right.

We speak to climate adaptation researcher Elizabeth Carabine to learn how communities and governments can use ecosystem services to estimate the value of their natural assets and protect them from industrial exploitation.

Finally, we travel to Ebola-stricken Sierra Leone to discover how Médecins Sans Frontières (MSF) armed local teams with motorbikes and GPS-enabled smartphones to map the disease.

SciDev.Net Podcast: Who are the missing millions?

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.

SciDev.Net podcast: African farmers mitigate emissions

In today’s programme, we hear about the Sustainable Development Goals (SDGs) and why there’s been a call to tweak one target relating to SDG 3, which seeks to ensure healthy lives and promote well-being for all at all ages.

The target calls for a one-third cut in premature mortality from non-communicable diseases by 2030. Although the basic idea is laudable, some researchers say the target discriminates against people older than 70. 

We then follow the footsteps of a researcher who has spent the last 15 years in Africa studying long-term, low-cost famine responses. He has found a way to bring seemingly dead trees back to life using a method called ‘farmer-managed natural regeneration’. 

And we travel to Nigeria where we meet tomorrow’s female scientists: schoolgirls taking part in a rubbish-themed competition using hand-made robots. We talk with the founder of the organisation that aims to ignite a passion for STEM (science, technology, engineering and maths) subjects among these girls through play and problem solving.

SciDev.Net Podcast: End age discrimination in the SDGs

When the media reports on the fight against tuberculosis, it’s usually the scientific innovations that get coverage — the hunt for more effective vaccines, drugs and diagnostic tools.  

But an issue that deserves attention is the creative approaches to TB care adopted by those shouldering most of the burden: nurses. In countries where health systems are poorly funded and understaffed — 95 per cent of TB deaths are in low- and middle-income countries — nurses play a vital role, often acting as the primary care givers for patients who might rarely, if ever, see a doctor. 

In this interview for World TB Day, we speak to Gini Williams, a TB nurse consultant and pioneer of nurse training programmes. “It’s no good having new diagnostics and treatments if you don’t have access to them and [don’t] have people who know how to use them,” Williams says. ”Services and systems around supporting patients are very important.”   

The “human nature” of TB — a debilitating disease that can take months or years to cure, where the effectiveness of treatment hinges on an individual’s needs, responses and circumstances  — demands treatments that take into account more than the purely medical, Williams says. Treatment requires a holistic approach factoring in in people’s social, economic, environmental situations and psychological needs. And nurses are often best-placed to address these and to provide the patient support and education so vital to controlling TB.

Yet nurses rarely get rigorous TB training — rarer still training that focuses on the breadth of approaches needed to tackle the disease. Williams and her colleagues at the International Council of Nurses TB Project have therefore created training courses  designed and run by nurses, for nurses. These have led to improvements in infection control, made diagnostic processes more robust, and have strengthened relationships between both labs and clinics, and nurses and patients. 

Nurses have also been trained to research what techniques work where and how to improve systems, Williams says. This both helps strengthen TB response, and means that nurses can take the lead in shaping interventions to improve the lives and treatment outcomes of millions of people.

The interview was recorded yesterday at King’s College London, United Kingdom, at the opening of an exhibition of photographs by TB nurses in South Africa, organised by TB researcher Uta Grosse.

In an audio interview, Peter Piot discusses a private-sector partnership that draws on tech and puts patients first.
 
The London School of Hygiene and Tropical Medicine (LSHTM) has teamed up with the philanthropic arm of the pharmaceutical company Novartis to test a new tack to managing the rising burden of chronic diseases in the developing world.

In an interview recorded this week at a symposium co-hosted by the pair, LSHTM director Peter Piot outlines elements of the partnership. He focuses on two elements: the need for a “systems design” approach to care that puts people first, and the promise of “evolutions and revolutions” in digital technology for areas where resources are in short supply, particularly Sub-Saharan Africa.

Four out of five patients who suffer from chronic conditions — 9.4 million people — live in low- and middle-income countries. But with little aid money and poor existing infrastructure, health systems are often too weak to offer the diagnostics and treatments needed for conditions like cardiovascular disease, diabetes, obesity or cancers.

And there are more barriers to care: people who struggle to make ends meet often can’t afford the time or the money to visit a hospital. Many are not even aware their health is at risk.

LSHTM’s work with the Novartis Foundation draws on a lesson from the management of HIV/AIDS and other infectious diseases, according to Ann Aerts, head of the Foundation: the need to build healthcare around the reality of patients’ lives. It relies on innovation in both technology and in the way services are delivered.

‘Evolutions and revolutions’ in chronic disease care

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.
