Analysing value chains in informal settlements: a how-to guide for community-led approaches – the case of building materials

This co-produced guide aims to capture an existing process and approach for data analysis being used by the Slum Dwellers International (SDI) network, using the value chain of building materials in informal settlements as an example. It aims to incorporate participatory learning and action methods and be tailored to local contexts. 

To take into consideration the heterogeneous nature of informal settlements, it allows for varied levels of mobilisation and collaboration with local stakeholders, as well as existing knowledge of housing and construction in different neighbourhoods. The approach is highly adaptable. 

We applied it to a building materials value chain, specifically to look at materials used for homes in informal settlements. However, this guide also usefully introduces communities to the wider concept of value chain analysis, and aims to provide guidance and practical tools that can be used to undertake similar exercises.
