Weather Mtaani – the local Nairobi brand of DARAJA – is an initiative that aims at improving access to and the usability of weather and climate information (weather forecasts, seasonal outlooks, weather warnings etc.) produced by the Kenya Meteorological Department (KMD) for Nairobi’s residents who live in informal settlements, like Kibera, Mathare, Dandora, Mukuru, Korogocho, Kangemi and others. This will enable residents to be more resilient and better prepared to take adaptive measures. The project also aims at enabling city authorities to make better climate and weather informed decisions in relation to urban informal settlements. DARAJA was a project under the Weather and Climate Information Services for Africa (WISER) East Africa programme which is funded by the FCDO and managed by the UK Met Office from 2018 to 2020.


DARAJA/Weather Mtaani was implemented by the DARAJA consortium which included Resurgence (UK), Kounkuey Design Initiative (KDI, Kenya) and Centre for Community Initiatives (CCI, Tanzania), in partnership with the Kenya Meteorological Department (KMD) and the Tanzania Meteorological Authority (TMA).
