Humanity is now majority urban, with predictions that urbanisation will increase to 66% of the human population by 2050. Along with the negative environmental impacts of urbanisation, people are being increasingly cut off from nature, leading to a growing interest in urban greenery and farming. Alongside this desire for a connection with nature, activities to make cities more self-sufficient in food to drive cost efficiencies as well as mitigate climate change have become more prominent in recent years.
One of the common ways of doing this has been the increasing support by businesses for green rooftops such in Hong Kong or community efforts for urban gardening in public plots and also schools. National governments have also become involved with a successful intervention by Antigua and Bermuda to support backyard gardens towards greater food self-sufficiency. High technology solutions such as hydroponics are also being developed as this example from London shows where a company is producing between 1.6 and 3.3 tonnes each month in a former air-raid shelter in London.
It is not the only vegetables that are being cultivated. Many coastal communities across the world are developing sustainable fisheries, ensuring a constant food supply and employment for local people. San Carlos (Negros Occidental) in the Philippines has won recognition for the revitalisation of its marine life due to its commitment to sustainable fishing and conservation, efforts which are helping increase tourism to its city.
What else is there? Which policies, instruments, frameworks, projects or initiatives do you know about? Are there policies in your country, region or city pushing for sustainable farming? Do you know about or are you involved in projects in your community, school or business that are supporting sustainable farming?
