As part of the Living Labs for People (LL4P) work in Nandi County, Kenya, under the CGIAR Research Initiative on “Low-Emission Food Systems,” researchers from the International Food Policy Research Institute (IFPRI) and the International Livestock Research Institute (ILRI) mapped major land use types in Nandi County using remote sensing and machine learning. The process begins with acquiring pertinent remote sensing data, followed by rigorous preprocessing to ensure accuracy and consistency |

As part of the Living Labs for People (LL4P) work in Nandi County, Kenya, under the CGIAR Research Initiative on “Low-Emission Food Systems,” researchers from the International Food Policy Research Institute (IFPRI) and the International Livestock Research Institute (ILRI) mapped major land use types in Nandi County using remote sensing and machine learning. The process begins with acquiring pertinent remote sensing data, followed by rigorous preprocessing to ensure accuracy and consistency. A key aspect is the collection of ground-truthing data—a vital step in training the machine learning model. During ground-truthing, the ILRI-Kenya team travelled around Nandi County collecting data on the land use type from over 1000 polygons (GPS points) in Nandi County. These points were used to train the machine learning model to identify different types of land use in the remote sensing data. The mapping results are visualized using advanced GIS techniques and presented on a cloud-based platform for accessible viewing. The availability of cloud-based platform enhances usability and scalability, fostering collaboration with users and partners seeking valuable insights into Nandi County’s land use dynamics.
