“We mapped out food poverty across England, to see where food banks are needed most”

Statistics from food banks across England show a frightening rise in the number of people using their services, meaning that more and more people don’t have enough money to feed themselves. Between 1 April 1 2016 and 31 March 2017, the Trussell Trust provided 1,182,954 three-day emergency food packages – up 73,645 from the previous year.

People affected by food poverty face severe threats to their health and well-being. As well as the stress, depression and anxiety that can result from not having enough money to feed their families, people experiencing food poverty also face a higher risk of obesity, because the only foods they can afford tend to be cheap, sugary, processed and fattening.

Some researchers have already mapped out who is using food banks, which is a big step towards understanding the problem. But academics like ourselves are increasingly concerned that just focusing on food bank data means we are not seeing the whole picture. After all, some people in need do not live near a food bank, or do not know about local services, or are too embarrassed or worried about what will happen if they tell people they cannot afford to feed their children properly.

These people are extremely vulnerable, since they’re not getting the crucial emergency support offered by food banks. Identifying and helping the unseen victims of food poverty should be a national priority. The obvious answer is to create a national measure of food poverty, like the ones used in the US and Canada. This would allow the government to identify those in need, and target resources accordingly.

Shockingly, no such measure is used in England, though some efforts are being made in Wales and Scotland. But there is a way to use existing data, to figure out not just how many, but crucially where vulnerable people might need emergency food.

Mapping out food poverty

We already know what types of people are more likely to experience food poverty: single pensioners, low income households with children and people claiming benefits are at greater risk. By combining this knowledge with big datasets such as the Census and data from the Department for Work & Pensions, it’s possible to find out where populations at risk of food poverty live.

As part of new research, we mapped out the number of people at higher risk of food poverty across all of England. Our map shows that some areas of the country face much higher levels of risk – and they’re not always the ones you might expect.

For example, when we updated our maps with the most recent data on benefits claimants, we found that areas in London such as Croydon and Southwark have a large proportion of residents facing a high risk of food poverty. Outside of London, some urban areas in the north (Liverpool, Manchester, Newcastle) have higher risk – even where these areas don’t always appear to be deprived using other measures.

When we compared those areas where people are at higher risk of food poverty with the locations of food banks from the Trussell Trust, we found that those areas don’t always have a lot of food banks. In fact, based on the available data, we couldn’t find a statistical relationship between the number of food banks in an area and the 2015 Index of Multiple Deprivation score, meaning that food banks are not always concentrated in the poorest areas.


Making a difference

Of course, this is not a criticism of food banks. They offer vital and often life-changing services. But more information about exactly where these invaluable services are needed could mean more vulnerable people receive the help and support they need to get through a difficult time.

Our maps can help with this, by helping local authorities put together food poverty action plans that target their resources more effectively. The data can be tailored for localities to account for the specific local problems which contribute to food poverty – such as the high housing costs in London boroughs, and the high rates of unemployment in many communities in the north-east of England. We are already working with local authorities around the country to this end.

The ConversationThis type of work is becoming more important, as controversial policy changes and cuts take hold. The roll out of Universal Credit looks set to make food poverty worse in some areas. By looking for food poverty hot spots in the local communities, researchers can help charities and local government to reach those in need.

Green roofs improve cities – so why don’t all buildings have them?

Rooftops covered with grass, vegetable gardens and lush foliage are now a common sight in many cities around the world. More and more private companies and city authorities are investing in green roofs, drawn to their wide-ranging benefits which include savings on energy costs, mitigating the risk from floods, creating habitats for urban wildlife, tackling air pollution and urban heat and even producing food.

A recent report in the UK suggested that the green roof market there is expanding at a rate of 17 per cent each year. The world’s largest rooftop farm will open in Paris in 2020, superseding similar schemes in New York City and Chicago. Stuttgart, in Germany, is thought of as “the green roof capital of Europe”, while Singapore is even installing green roofs on buses.

These increasingly radical urban designs can help cities adapt to the monumental challenges they face, such as access to resources and a lack of green space due to development. But buy-in from city authorities, businesses and other institutions is crucial to ensuring their success – as is research investigating different options to suit the variety of rooftop spaces found in cities.

A growing trend

The UK is relatively new to developing green roofs, and governments and institutions are playing a major role in spreading the practice. London is home to much of the UK’s green roof market, mainly due to forward-thinking policies such as the 2008 London Plan, which paved the way to more than double the area of green roofs in the capital.

Although London has led the way, there are now “living labs” at the Universities of Sheffield and Salford which are helping to establish the precedent elsewhere. The IGNITION project – led by the Greater Manchester Combined Authority – involves the development of a living lab at the University of Salford, with the aim of uncovering ways to convince developers and investors to adopt green roofs.

Ongoing research is showcasing how green roofs can integrate with living walls and sustainable drainage systems on the ground, such as street trees, to better manage water and make the built environment more sustainable.

Research is also demonstrating the social value of green roofs. Doctors are increasingly prescribing time spent gardening outdoors for patients dealiong with anxiety and depression. And research has found that access to even the most basic green spaces can provide a better quality of life for dementia sufferers and help prevent obesity.

In North America, green roofs have become mainstream, with a wide array of expansive, accessible and food-producing roofs installed in buildings. Again, city leaders and authorities have helped push the movement forward – only recently, San Francisco created a policy requiring new buildings to have green roofs. Toronto has policies dating from the 1990s, encouraging the development of urban farms on rooftops.

These countries also benefit from having newer buildings, which make it easier to install green roofs. Being able to store and distribute water right across the rooftop is crucial to maintaining the plants on any green roof – especially on “edible roofs” which farm fruit and vegetables. And it’s much easier to create this capacity in newer buildings, which can typically hold greater weight, than retro-fit old ones. Having a stronger roof also makes it easier to grow a greater variety of plants, since the soil can be deeper.


The new normal?

For green roofs to become the norm for new developments, there needs to be buy-in from public authorities and private actors. Those responsible for maintaining buildings may have to acquire new skills, such as landscaping, and in some cases volunteers may be needed to help out. Other considerations include installing drainage paths, meeting health and safety requirements and perhaps allowing access for the public, as well as planning restrictions and disruption from regular ativities in and around the buildings during installation.

To convince investors and developers that installing green roofs is worthwhile, economic arguments are still the most important. The term “natural capital” has been developed to explain the economic value of nature; for example, measuring the money saved by installing natural solutions to protect against flood damage, adapt to climate change or help people lead healthier and happier lives.

As the expertise about green roofs grows, official standards have been developed to ensure that they are designed, built and maintained properly, and function well. Improvements in the science and technology underpinning green roof development have also led to new variations on the concept.

For example, “blue roofs” increase the capacity of buildings to hold water over longer periods of time, rather than drain away quickly – crucial in times of heavier rainfall. There are also combinations of green roofs with solar panels, and “brown roofs” which are wilder in nature and maximise biodiversity.

If the trend continues, it could create new jobs and a more vibrant and sustainable local food economy – alongside many other benefits. There are still barriers to overcome, but the evidence so far indicates that green roofs have the potential to transform cities and help them function sustainably long into the future. The success stories need to be studied and replicated elsewhere, to make green, blue, brown and food-producing roofs the norm in cities around the world.
