Climate change may increase ‘hidden hunger’

Lucia Grenna heads a World Bank unit that specialises in climate change-related communication. In 2011, she set up a communication initiative called Connect4Climate, which has grown into a major global partnership of organisations and individuals committed to climate change action. Her task, she says, is “to listen to and to engage unusual audiences” and to make people realise that the term “climate change’’ in itself does not have a message.

Q&A: Lucia Grenna and her Connect4Climate initiative

In lead to December’s 20th UN Conference of Parties on climate change, scientists and policymakers are reflecting on the future of climate science. Many are questioning whether the existing mechanisms that feed scientific evidence into international politics are working well enough.

In this interview Ilan Kelman argues that, despite its important work, the Intergovernmental Panel on Climate Change, with its consensus-based approach, is no longer suited to the new challenges posed by climate change.

What’s next for climate science beyond the IPCC?

According to the WHO, bad air quality was responsible for 7 million deaths in 2012. In this interview Paulo Saldiva, dean of the department of pathology at the University of São Paulo, explains that there are no measures to protect people against air pollution, and so public health policies are vital to avoid serious consequences, particularly in large cities. He says the science needed to address the risks of air pollution is in place, but that poor countries lack the resources to implement it with solutions that work locally.

Public health responses to the Ebola crisis neglected to build trust among affected people, and more must be done to engage with the ‘human factor’ when disease outbreaks occur, anthropologist Heidi Larson warns in this audio interview. 

Larson, director of the Vaccine Confidence Project at the London School of Hygiene & Tropical Medicine, United Kingdom, says crisis response programmes must address public fears around disease. One critical lesson to emerge from the Ebola epidemic, she says, is that failing to focus on communication and trust-building with communities early on can lead to heightened fears and misinformation that jeopardises safety and helps a disease spread.

Social scientists and medical experts need to work hand-in-hand to devise responses, Larson says, because “a public health or medical expert and an anthropologist will look at the same situation and notice very different things”.

The interview was recorded at ‘Ebola – The 21st-century plague?’, a conference at the Royal Society of Medicine, United Kingdom, on 6 February.

Q&A: How building community trust helps combat epidemics

Although antiretroviral drugs are not a cure, they can stop people infected with HIV from developing AIDS by keeping the amount of virus in the body low.

This audio feature explores a UK trial that used the antiretroviral drug Truvada to prevent a group of homosexual volunteers, considered at risk of contracting HIV, from doing so. Although the drug was successful in the United Kingdom, experts warn that more effort will be needed to develop targeted campaigns to administer the treatment  in regions where HIV is endemic, such as Sub-Saharan Africa.
