Water management among the Chagga people of Kilimanjaro has involved community collaboration in the construction, ownership and management of water infrastructures. Since the second half of the second millennium AD, the Chagga settlement on the lower slopes of Mt Kilimanjaro significantly transformed the landscape to reflect an agrarian society characterised by decentralised forms of socio-political and economic organisation. Such organisation involved conception, construction, and post-construction management of water distribution systems, synonymous with high levels of socio-political complexity. The study employs ethnography and archaeological surveys to document the construction of water infrastructures on the lower slopes of Mt Kilimanjaro. An ethnographic survey among Chagga elders generated primary data on water furrow construction. This information was then used to aid archaeological surveys in mapping irrigation furrows (mfongo) in the lower slopes of Mt Kilimanjaro. The ethnography also provided data on how Chagga chiefs and clan leaders governed the construction, use and maintenance of water infrastructures in the past. Such approaches highlighted Chagga lived experiences of traditional irrigation technologies and infrastructures and how these developed a complex agrarian society. Results show that community collaboration was key in the management of water infrastructure vital for their home gardens, and this sustained Chagga society for centuries. Full article

Mountain environments and communities are disproportionately impacted by climate change. Changes in temperature are greater than at lower elevations, which affect the height of the cloud base and local rainfall patterns. While our knowledge of the biophysical nature of climate change in East Africa has increased in the past few years, research on Indigenous farmers’ perceptions and adaptation responses is still lacking, particularly in mountains regions. Semi-structured interviews were administered to 300 farmers on Mount Kilimanjaro (n = 150) and the Udzungwa Mountains (n = 150) in Tanzania across gender and wealth groups. Respondents in both mountains reported not only changes in rainfall and temperature, corresponding with meteorological data, but also a greater incidence of fog, wind, frost, and hailstorms—with impacts on decreased crop yields and increased outbreaks of pests. The most common adaptation strategies used were improved crop varieties and inputs. Wealthier households diversified into horticulture or animal rearing, while poorer households of Hehe ethnicity diversified to labour and selling firewood. Despite being climate change literate and having access to radios, most respondents used Indigenous knowledge to decide on planting dates. Our findings highlight how context and culture are important when designing adaptation options and argue for greater involvement of local stakeholders in adaptation planning using a science-with-society approach. Place-based results offer generalisable insights that have application for other mountains in the Global South. Full article
