Community and environmental sustainability are a global concern that calls for the civilised, the professional practitioners, the creative thinkers, and the future world to participate in providing, creating and establishing a sustainable environment. This study aims at stimulating and informing the discussion on the concept of community and environmental sustainability, as well as on how technology has influenced it. It explores African concepts of environmental sustainability with relevant examples from the Kikuyu and the Luhya communities in Kenya. The chapter highlights an African imagination of community and its role in the conservation of natural resources, and the creation of sustainable economic conditions for African communities. A survey was conducted in Roysambu, a small village in Nairobi, Kenya. The study picked a sample of 150 respondents in the area, who were selected using random sampling. One stipulation in this selection was that each of the members of the study sample was either from the Kikuyu or Luhya communities. The study also adopted the diffusion of innovation theory, which explains that over a duration of time, an innovation or idea is adopted by users and spreads in a given social system or population (Rogers, 1983). The study established that it is important for communities to live according to their traditions and values despite the intense technological wave, with the support from the government, in order to create a balance between traditional ways and the technological ways of establishing a sustainable environment.
