Policies to increase food security in the global South focus too much on rural food production and not enough on ensuring poor people can access and afford food, especially in urban areas, says a report published on Thursday by the International Institute for Environment and Development.
It warns that climate change will only make this policy gap worse, because its impacts will affect not only harvests, but also the systems that people use to transport, store and buy and sell food.
"Food security is back on the agenda thanks to rising prices and the threat that climate change poses to agricultural production," says the report's author, Dr. Cecilia Tacoli. "But policies that focus on rural food production alone will not tackle the rising food insecurity in urban areas. We also need policies that improve poor people's ability to access and afford food, especially in urban areas."
Most people in urban areas must buy their food and this makes the urban poor particularly at risk. Any climate-induced disruption to food production, transport and storage – either in the urban area itself or in distant farmland – can affect food supplies and prices in urban areas, according to the report.
Yet most policies that aim to increase food security focus solely on boosting production from farms and fisheries in rural areas.
"The journey that food takes from a rural producer to an urban consumer involves many steps," says Tacoli. "It must travel through formal and informal systems as it is stored, distributed and sold. Each one of these steps is a point of potential vulnerability to climate change. For consumers, this will mean sharp and sudden increases in food prices"
The report highlights the link between income poverty and food insecurity in urban areas. For most low-income urban citizens, food represents a sizeable portion of the money they spend. Even small increases in price would, therefore, have big impacts on food security, with citizens reducing the amount and quality of the food they buy.
For the residents of informal urban settlements, food insecurity is also the consequence of lack of space to store and cook food, lack of time to shop and prepare meals, inadequate access to clean water and often non-existing sewage systems.
These settlements are disproportionately affected by floods, typhoons, heat waves and other impacts of climate change because they tend to be located in areas more exposed to these events, and because they lack the most basic infrastructure.
