More than 30% of car journeys in Europe are under 3km long and could potentially be swapped for different, greener, forms of transport. In February, we look at alternative ways of getting people and goods around cities - a challenge known in the industry as the problem of the ‘last mile’. We speak to Karen Vancluysen of cities network POLIS, who says that cities may have to introduce some unpopular measures to change the way people move around, and we look at how soon commuters will be able to rely on automated shuttles to ferry them from door to door. We delve into the environmental problems caused by unsuccessful home deliveries and what can be done about them, and the new technologies that could change the way goods are delivered.
In the zero-carbon cities of the future, commuting to work may take the form of hailing a driverless shuttle through an app which ferries you from your door to the nearest public transport terminal. In fact, autonomous shuttles have been in development in restricted areas for the past few years. So what will it take to make them part of our daily commute?
Delivering online shopping to people’s homes is a huge source of greenhouse gas emissions, particularly when deliveries fail and the journey needs to be repeated. Researchers are now re-thinking home deliveries to see if there is a better way of doing things, with ideas including robot couriers, jointly owned parcel lockers and an ‘Uber’ for parcels.
Across Europe’s cities, the demand for delivery services is increasing. But these deliveries affect urban life as they add to traffic congestion, noise and pollution and many cities are now trying out alternative modes of transport that could help.
How people and deliveries get to their final destination is currently making urban environments harder places to live, and cities need to solve this ‘last mile problem’ by using a combination of ‘carrot and stick’ measures, according to Karen Vancluysen, secretary general of Polis, a network of European cities and regions working on sustainable innovative transport solutions.
In June, against a backdrop of the coronavirus pandemic, a climate emergency and an uncertain future, Horizon takes a look at anxiety. Are we becoming more anxious? What do we really know about the condition and who suffers from it? And how can we best treat it? We speak to anxiety disorder expert Professor David Baldwin about when anxiety turns from a normal response into a long-term problem and what we know – and don’t – about why this happens. We take a look at one particularly vulnerable group – teenagers – to understand how anxiety affects them and how they can best be treated. We explore the link between anxiety and our awareness of bodily sensations to understand, for example, why breathing can calm the mind, and we also talk to the researchers who believe the key to improving anxiety therapies is to look at how different people respond when under threat.
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.
In our continuing search for other life in the universe, one place has always looked promising – Mars. It is a rocky planet like Earth, orbiting the same star, and at a distance where water could have been present on the planet.
Moving more goods by water could reduce pressure on roads and cut emissions, yet Europe’s shipping industry is held back by labour shortages. Automated shipping – which would work in a similar way to self-driving cars – could help expand capacity but safety and regulatory hurdles remain.
The red planet may be our best bet for finding out whether we’re alone in the universe.
Reducing crew numbers onboard ships could overcome labour shortages and increase shipping levels.
Metagenomics can help us spot emerging diseases such as coronavirus, says virologist Marion Koopmans.
