Grassroots Initiatives for Urban Sustainability Transition: A Case Study of Urban Farming Projects in Informal Settlements in Nairobi, Kenya

Abstract: Cities in the Global South are undergoing rapid urbanization, where a high percentage of the urban poor live in informal settlements that lack basic services, are associated with unemployment, low-income levels, and insecurity. The impacts of climate change, intensive agricultural practices, and highly globalized food systems pose challenges to food security. Urban farming is one of the alternative practices to tackle food insecurity and urban poverty. In this study, urban farming was examined through grassroots innovation theory, which focuses on creating innovative sustainable development solutions from the bottom up. However, insufficient research has been done on urban farming initiatives in highly deprived areas. A qualitative approach was adopted, where semi-structured interviews were conducted, that were triangulated with observation and documentation data, providing multiple sources of support. The data was analysed through the Resources-Rationales-Relations Framework, which has been also used by other researchers to analyse grassroots initiatives. The results demonstrate that water is a crucial resource in urban farming grassroots initiatives, as water availability is limited due to droughts and climate change. Furthermore, resource-scarce environments experience limited access to water due to the unequal distribution of resources. Another identified resource that urban farming grassroots initiatives imply is climate-smart innovative technologies, such as the hydroponic system, that gives farmers good exposure. Sustainable livelihood creation was the main rationale to be involved in urban farming grassroots initiatives, by creating employment, giving back to the community, and influencing youth’s food and lifestyle choices. Relations were found to be crucial between farmers and organizational intermediaries, as they have increased their visibility and enabled them to engage with a wider context. The study concludes that the urban sustainability transition in Global South’s informal settlements is achieved when it cuts through all three levels of knowledge production, which was done by the climate-smart innovative farming technologies that raise attention and interest beyond the local context up to the political arena.
