A new paper, led by Lisa-Marie Hemerijckx, was published in a special issue of Remote Sensing dedicated to methods for population mapping. The article, “Upscaling Household Survey Data Using Remote Sensing to Map Socioeconomic Groups in Kampala, Uganda“, demonstrates a method to upscale household survey data to city level, using satellite information, to create base maps for further analysis. The paper shows the likely distribution of socioeconomic clusters throughout Kampala, and is based on a household survey administered by Food4Cities in Kampala in 2019.
On 10 October 2019, Food4Cities researcher Lisa-Marie Hemerijckx was selected by the Research Foundation Flanders (Fonds Wetenschappelijk Onderzoek, FWO) to receive a personal PhD fellowship for her research project on urban food systems in African cities. During the next 4 years, she will be mapping out the foodsheds of Kampala in her project, titled: “Spatial analysis of food systems transformations in rapidly growing African cities”.
On 13 September 2019, the Institute for Environmental Management at VU University Amsterdam hosted an international symposium on paths for sustainable food systems transformation. Food4Cities coordinator Jac Davis presented the Environmental Geography group’s approach to food systems research: involve diverse stakeholders early, take a holistic view, and iterate fast. The symposium sparked hot debates over controversial topics such as GMOs, trade, vegan diets, farm size, organic agriculture, subsidies… and highlighted persistent action and knowledge gaps that need to be addressed to build a better and more sustainable food system.
On Wednesday 5 June 2019, Nyasha Magadzire
presented a talk under the theme “Feeding our future cities” at the GBCSA
(Green Building Council of South Africa) Cape Town offices. The GBCSA is
involved in the development and adoption of best green building practices so
that all buildings are designed, built and operated in an environmentally
sustainable way. In line with the mandate of the GBCSA, Nyasha`s talk focussed
on how future cities could be designed to meet the nutritional and dietary
needs of urban populations in a more sustainable manner.
Some of the key
interventions highlighted included:
Adopting innovations and
technologies that require less area to sustain city food needs and reclaiming
previously farmed land for biodiversity conservation.
Producing food within cities.
Even distribution of healthy
nutritious food across the city.
Donating surplus food to
charities, feeding programs, etc
Follow up discussions between Nyasha and the audience centred around
difficulties in gaining the necessary institutional support from government for
a more food sensitive urban design. Other discussions included the role of big
retailers and urban agriculture in improving access to nutritious food in the
Feeding Africa’s cities is an urgent
development challenge. By 2050, 70% of the world’s population will live in
cities, and Africa will account for more than two-thirds of this growth. Costs
of food insecurity and malnutrition – historically considered a rural problem –
will increasingly be transferred to cities. The Food4Cities team is developing
tools to help African cities plan to face these challenges.
Food4Cities combines statistical
models for urban growth, land use change, and food access to understand the
links between city food systems and the broader land system. This model
integration allows us to explore future scenarios, analyse trade-offs, and
identify opportunities for system transformation.
In February 2019, members of our project team visited key sites and met with planning and delivery partners in our two case study cities: Cape Town, South Africa and Kampala, Uganda. They spoke with government officials and food system specialists about how to feed these rapidly growing cities. In June 2019, we plan to visit our partners again to workshop our model and get their feedback on the prototype versions. Through these processes of stakeholder engagement and knowledge co-production, Food4Cities aims to produce useful results for planning future food systems in rapidly changing African cities.
By 2050, 70% of the world’s population will live in cities. Africa will account for more than two thirds of this growth, and costs of food insecurity and malnutrition – historically considered a rural problem – will increasingly be transferred to cities. Acknowledging this challenge, this project aims to promote sustainable and nutrition-secure city food systems in Africa by developing knowledge and tools for local and national development planning.
Conventional responses to food security have stemmed from agriculture, framing food security as a production problem. However, a focus on production alone will not solve food insecurity and malnutrition in Africa’s cities. Most food-insecure households are limited more by food access, which is affected by drivers like poverty, price volatility, availability of healthy foods, market structures, and supply disruption from environmental degradation, natural disasters and climate change. Interventions addressing city food insecurity and malnutrition therefore need to consider these drivers, as well as interactions beyond the city. City food demand strongly shapes the peri-urban and rural landscapes that produce the food, or even distant areas through global markets. These effects themselves create feedbacks that influence city food and nutrition outcomes.
Considering these complex dynamics requires broader thinking about food, beyond single disciplines or sectors, accounting for the full set of activities across food chains. This project links within-city food systems to broader land systems. Such model integration allows quantification of how changes within and beyond the city influence city food and nutrition outcomes over time, thus making explicit the synergies/trade-offs with other desired outcomes, e.g. Sustainable Development Goals (SDGs).
The project uses two case studies to develop planning tools for enhancing city food and nutrition security: Kampala, Uganda and Cape Town, South Africa. Both city food systems are changing rapidly – Cape Town with a longer history; Kampala more recently. Urban expansion threatens productive croplands around both cities, with Kampala identified as a hotspot of global cropland loss. Food production is also threatened by changes in ecosystems and climate. There is a strong trend toward consolidation across the food chain (production, processing and retail), making market-entry for small-scale operators difficult. Patterns of socio-economic segregation dominate, with poverty-concentrated areas showing high levels of malnutrition and limited access to affordable, nutrition-rich foods. Formal and informal food networks in poor areas are strongly coupled and play an important role in food access and affordability. Objectives of the project are to:
Develop models to link within-city food system dynamics to dynamics of the broader landscape
Co-develop scenarios of city food futures
Evaluate scenarios in terms of city food and nutrition outcomes, and equitable ecosystem benefit flows and economies across the urban, peri-urban and rural landscape
Identify opportunities and interventions for building positive food futures in local and national development planning, and highlight multiple co-benefits
Reflect on case study lessons for scaling impact elsewhere
