Feeding the world's cities: a critical challenge for sustainable development

Food security and nutrition needs to be integrated into urban planning and development, says UN FAO.

Providing healthy diets for the world’s growing urban population requires forging stronger links between rural producers and urban markets and building food systems that are more socially inclusive, environmentally sound and less wasteful, FAO Deputy Director-General for Natural Resources, Maria Helena Semedo, said on Friday.

She spoke at the opening of an FAO-organized meeting at theGlobal Forum for Food and Agriculture (GFFA) taking place during this year’s International Green Week in Berlin, from 15-24 January 2016.

Semedo warned of the difficulties that many cities face in ensuring regular and stable access to adequate food for all. “This will worsen as an increasing proportion of the hungry will be living in urban areas,” she said.

More than 50 per cent of the world’s population currently lives in urban areas and this is expected to rise to 70 percent by 2050, particularly in developing countries.

Increasing effects of climate change, including storms, floods and other extreme weather events, pose an added threat to how people in cities, especially the poor, access food.

Re-shaping food systems and making them more sustainable

To address these needs, food systems - from production, distribution and consumption - must be made more sustainable, according to FAO. This includes guaranteeing access and active involvement of all stakeholders, farmers and smallholders, along the whole supply and value chain.

Crucial to this is drastically reducing food losses and waste, which are especially high in urban areas. This includes measures such as redistributing edible unused food and using waste as compost or to generate energy.

Semedo underscored the role played by rural populations in contributing to the food security of those who live in cities.

“Feeding cities creates considerable opportunities for sustainable development - both in cities and in rural areas - especially when family farmers and small-holders are linked to these markets,” Semedo said.

Urban and peri-urban agriculture is also an important component of food systems with innovative techniques such as hydroponics - growing plants in water solutions containing minerals - and home and vertical gardens providing prospects to create jobs, offer nutritional diversity and contribute to healthy eating in towns and cities.

Integrating food into urban planning “essential”

Food security and nutrition “often remains overlooked” in urban planning and development but this must be changed if the international community is to achieve Sustainable Development Goal 11 of the 2030 Agenda for Sustainable Development which entails making cities inclusive, safe, resilient and sustainable, Semedo said.

To this end, “integrating food into urban planning is essential,” she stressed, noting that while city and metropolitan governments are increasingly taking part in local, national and global dialogues on food systems, “more needs to be done”.

This should be an inclusive process, bringing together government, the private sector and civil society, in ways that reflect the social, economic and ecological complexities of food systems, Semedo added.

Global networks of cities and the Milan Urban Food Policy Pact

There is a need for cities to share their experiences through global networks, as a way to spur a wider adoption of good practices. As an example of this, Semedo cited the Milan Urban Food Policy Pact approved by over 100 municipalities from around the world at the Milan Expo in October 2015. A world mayors’ meeting is to be hosted by FAO in 2016 to support work related to the Pact.

For its part, FAO is also partnering in and spearheading various initiatives such as Food for the Cities, and Meeting Urban Food Needs.

Semedo is scheduled to address an agriculture ministers summit on Saturday 16 January 2016, which is also part of the GFFA.
