Kenya Markets Trust (KMT) is a multi-donor funded organisation that works to improve lives by transforming three sectors using a Market Systems Development (MSD) approach: agricultural inputs, livestock, and water. Over the past two years, we have supported KMT to design and operationalise a new Monitoring, Research and Evaluation (MRE) system that strengthens their ability to prove and improve their impact. This has included working with sector teams to develop intervention plans and supporting the MRE team to upgrade the way in which data is collected, analysed, aggregated, reported, and used.
