These data were used to assess the contribution of the industrial sector to overall water demand. Livestock sector: Data on livestock water requirements, including animal types, population sizes, and daily or seasonal water consumption, were collected through surveys and interviews with farmers and livestock owners. Information on water sources used for livestock, such as rivers, ponds, and dedicated water troughs, was also recorded to evaluate the sector’s contribution to total water demand. 2.3 Simulating implications of various scenarios using the WEAP model 2.3.1 Model setup and calibration The data gathered from hydrological, water quality, and demand sources were meticulously organized and formatted for compatibility with the WEAP model. This step ensured that the data could be effectively utilized within the modeling environment to simulate water resource dynamics. Subsequently, the WEAP model underwent a calibration process, where it was adjusted using historical data to match real-world observations of water availability and demand within the Middle Nzoia River Catchment (Fard and Sarjoughian, 2019). This calibration was essential to ensure that the model accurately reflected past hydrological conditions and provided reliable outputs for future scenario analysis. 2.3.2 Scenario development Several future scenarios were developed in the WEAP model to assess the potential effects of different drivers on water resource management in the Middle Nzoia River Catchment. The scenarios were designed to evaluate how
