PID in water management in Tigray, Ethiopia
One of the local innovations identified by the Northern Typical Highlands platform of Prolinnova–Ethiopia is an intricate system of harvesting water from waterlogged land so as to allow cultivation in the long wet season, coupled with storage of this harvested water to use for supplementary irrigation in the following dry season. This had been developed by Mr Abadi Redehay, a 45-year-old man who lives in Mai Berazio village of Tahtai Maichew District in northern Ethiopia. See the paper here.
