Many researchers have been conducted, addressing rapid urbanisation in major sub-Saharan African cities. Although the increase in informal settlements and their association to natural landscape and environmental degradation are addressed, the application of rural low-key landscape development and adaptation techniques as measures to impart towards nature based urban informal development is not highlighted. This research was carried out to explore indigenous innate practices in interacting with nature on the slopes of Mt. Kilimanjaro as rural informative case study area. The same was done to investigate residents' techniques and development process in a conformative unplanned settlement of the Mbezi River catchment, in the rapidly growing City of Dar es Salaam. Adopting Case method, both qualitative and quantitative approaches were used for data collection and analysis. Observations, photo registry, sketching, maps studying, literature review, interview and mapping were employed. Relevant materials were applied. It was found that the landscape resilience attained by indigenous nature based development techniques from household level (small scale) to river level (large scale) inter-connectedly were geared by cultural homogeneity. The inconsistency and egoistic techniques by residents in the Mbezi Rive catchment area were underpinned by socio-economic and attitudinal diversities. Lessons extracted from the indigenous practices were transferred to the informal urban development through and established model by this study. The indigenous green infrastructure techniques in development, seems to be a remedial approach to transforming urban development culture, if well integrated in human-land interaction process to ameliorate urban ecosystem and mitigate adverse climatic impacts in the unplanned urban setting. Enforcement of the environmental regulations is primary to natural systems protection if resilient landscape urbanism is to be achieved.
