By 2050, the world’s population will be an estimated 9.7bn people, up from today’s 7.7bn. To feed this growing population whilst also protecting the climate and biodiversity, our food system needs to change dramatically. In May, we look at what sort of future food system we want and how to get there. We speak to sustainability expert Prof. Peter Jackson about how lockdowns have exposed our reliance on fragile supply chains, and what needs to happen to shape a more sustainable food system. We look at the smart farming solutions that are being explored to support food producers, and urban experiments from tackling food waste to strengthening organic, local production to see how these efforts can be scaled up to make a big difference. And we investigate insects – a protein-rich food and feed source – and the efforts behind mainstreaming what is still a niche science.
With the world in the grip of the coronavirus pandemic, in April Horizon takes a step back to look at some of the challenges around sudden outbreaks of emerging diseases. We speak to virologist Prof. Marion Koopmans about the likelihood of future outbreaks of new diseases, what causes them and how to spot them before they appear. We speak to scientists who are helping to develop tests for Covid-19 to understand the challenges in coming up with an accurate and detailed diagnostic test for an entirely new disease. We talk to people working on coronavirus treatments about how to shorten the normally lengthy process of drug development. And we look into why diseases suddenly jump from animals, such as bats, into humans and the particular challenges of spotting and responding to these types of outbreaks.
Dr Luciano Zuccarello grew up in the shadow of Mount Etna, an active volcano on the Italian island of Sicily. Farms and orchards ring the lower slopes of the volcano, where the fertile soil is ideal for agriculture. But the volcano looms large in the life of locals because it is also one of the most active volcanoes in the world.
