Urban Farming: Four Reasons It Should Flourish Post-Pandemic

Since lockdown, public interest in growing fruit and vegetables at home has soared. Seed packets are flying off shelves and allotment waiting lists are swelling, with one council receiving a 300% increase in applications. Fear of food shortages will have motivated some, but others with more time on their hands at home will have been tempted by the chance to relieve stress doing a wholesome family activity.
The seeds of enthusiasm for home-grown food may have been sown, but sustaining this is essential. Urban farming has much to offer in the wake of the pandemic. It could help communities boost the resilience of their fresh fruit and vegetable supplies, improve the health of residents and help them lead more sustainable lifestyles.
Here are four reasons why food growing should become a perennial feature in our gardens, towns and cities after COVID-19.
1. Growing greener towns and cities
More than half of the global population lives in urban areas, and this is expected to rise to 68% by 2050. For the UK, this is even higher – nine out of 10 people are expected to live in towns and cities by this time.
Weaving food growing into the fabric of urban life could bring greenery and wildlife closer to home. The COVID-19 lockdown helped reawaken interest in growing at home, but one in eight UK households have no access to a garden. Thankfully, the opportunities for urban farming extend beyond these: rooftops, walls – and even underground spaces, such as abandoned tunnels or air raid shelters, offer a range of options for expanding food production in cities while creatively redeveloping the urban environment.
Edible rooftops, walls, and verges can also help reduce flood risk, provide natural cooling for buildings and streets, and help reduce air pollution.

2. Resilient food supplies
Diversifying where and how we grow our food helps spread the risk of disruption to food supplies.
The UK’s reliance on imports has been growing in recent decades. Currently, 84% of fruit and 46% of vegetables consumed in the UK are imported. Brexit and COVID-19 could threaten the steady supply, while the problems created by climate change, such as water scarcity, risk disrupting imports of food from abroad.
Growing fruit and vegetables in towns and cities would help resist these shocks. The harvest labour shortages seen during the pandemic might not have been felt as keenly if urban farms were growing food right where people live.
Vertical and underground crops are more resilient to extreme weather or pests, indoor growing environments are easier to control than those in the field, and temperature and humidity is more stable underground. The high start-up costs and energy bills for this type of farming has meant that indoor farms currently produce a small number of high-value crops, such as leafy greens and herbs. But as the technology matures, the diversity of produce grown indoors will expand.

3. Healthier lives
Getting out into nature and gardening can improve your mental health and physical fitness. Our research suggests that getting involved in urban food growing, or just being exposed to it in our daily lives, may also lead to healthier diets.
Urban growers may be driven to make healthier food choices for a whole range of reasons. They have greater access to fresh fruit and vegetables and getting outdoors and into nature can help reduce stress, making people less likely to make unhealthy food choices. Our study suggested that urban food growing can also help change attitudes towards food, so that people place more value in produce that’s sustainable, healthy, and ethically sourced.
4. Healthier ecosystems
While urbanization is regarded as one of the biggest threats to biodiversity, growing food in towns and cities has been shown to boost the abundance and diversity of wildlife, as well as protect their habitats.
A recent study found that community gardens and allotments act as hotspots for pollinating insects, because they tend to contain a diverse range of fruiting and native plants.

If designed and implemented properly, allotments and community gardens can really benefit biodiversity. Not only should barren spaces be converted into green and productive plots, it’s also important that there are connections between these environments to help wildlife move between them.
Canals and cycle paths can act as these wildlife corridors. As we begin to diversify the spaces used to grow food, particularly those on our rooftops and underground, an exciting challenge will be finding novel ways of connecting them for wildlife. Green bridges have been shown to help wildlife cross busy roads – perhaps similar crossings could link rooftop gardens.
All these reasons and more should compel us to scale up food production in towns in cities. COVID-19 has given us cause to reevaluate how important local urban green spaces are to us, and what we want from our high streets, parks, and pavements. Judging by the garden center sales, allotment lists, and social media, many people have decided they want more fruit and veggies in those spaces. The opportunity is there for urban planners and developers to consider what bringing farming to urban landscapes could offer.

Dubai's Green Revolution Starts At Its Vertical Farms in The Middle of The Desert

Dubai is determined to start its green revolution through its ultra-modern vertical farm in the middle of the desert. The country decided on this project, hoping to end its dependency on food imports. One of the vertical farms in Dubai, Al-Badia market garden farm, grows a range of vegetable crops in a multi-story set-up. Inside the facility, they make sure that the plants get proper lighting and irrigation while recycling 90% of the water the facility uses.
Basel Jammal, the farm's director, said that their project is a green revolution located in the middle of the desert. It is as if the crops were a guest in a five-star hotel complete with amenities essential for its survival: the right amount of light, humidity, heat, and water.

Dubai's Vertical Farm
The United Arab Emirates relies heavily on food imports, and Dubai is no exception to that. However, food security is of concern, especially in a region where geopolitical tensions may arise unexpectedly.
The UAE started buying and leasing agricultural lands in east Africa and in other countries to prevent food shortages even in times of crisis more than ten years ago, . But they aim to eradicate dependence on food imports, giving birth to different agricultural strategies, such as stockpiling and ultra-modern agriculture.
Jammal said that his farm is the "choice for the future" as high-tech computers control the facility. They aim to produce their own crops all year round without relying on imports, or worrying about climate change, drought, or rainfall.
Several vertical farms have also started in Dubai in the past years, such as in less-developed areas in Al-Ain and the mountainous Ras al-Khaimah.
Abdellatif al-Banna uses the hydroponics technology in growing his pineapples that he sells online. He experimented with growing fruits, vegetables, and wheat on his farm. Even in colder months, he was able to produce enough grain for his family in what he hopes as a prototype.
Meanwhile, in an area not far from the skyscrapers of Dubai is a farm that cares for cows in air-conditioned sheds, helping the local market to produce dairy products. They were also rearing salmon in large tanks overseen by a control room despite the scorching heat outside the farm.
Dubai Has More Than Enough Food for the Entire Country
Although these vertical and high-tech farms are privately owned, the government is even encouraging such innovations, said Dubai's Food Security Committee chair Omar Bouchehab.
The Emirati government has launched a plan to raise agricultural production in Dubai by 15% in 2021 and boost using agricultural technologies, Bouchehab said.
AT THE BEGINNING OF THE PANDEMIC, Dubai did not experience shortages in food supplies, unlike other countries that saw shelves stripped of tinned goods, pasta, and toilet papers. It's all thanks to the airborne cargo services of the giant carrier Emirates. The country even promised to re-export various goods to its neighboring countries."
Dubai has an adequate infrastructure and a stock capable of meeting the needs of the United Arab Emirates, and even the needs of neighboring countries," said Fresh Market Executive director Redha al-Mansouri.
