Full title: Sustainable Land Management in Sub-Saharan Africa_ No 4. Road Runoff harvesting
These mini-films show a series of Sustainable Land Management (SLM) practices that have been proven in Sub-Saharan Africa. As well as helping to control land degradation and improve production, the practices constitute important components within the climate change adaptation strategies of small-scale farmers.
In this fourth film, Critchley explains road runoff harvesting, which is carried out in many parts of the world – wherever there is a combination of dry conditions and farmland alongside a road. It shows how roads provide a hard surface with a high runoff coefficient and drainage is integral to a road design. With this system, water may be spread immediately (eg for cereals), or ponded and then used for supplementary irrigation (for horticultural crops –both vegetables and fruit trees)
