New research has revealed that Tanzania’s official statistics on irrigation often don’t include initiatives set up and run by individual farmers. This is either because they’re not aware of it, or because they don’t consider it to have much potential.
Compared to formally engineered projects, this ‘farmer-led’ irrigation is often small-scale and interspersed among non-irrigated fields. This makes it harder to record. It also takes diverse forms. These range from watering via pumps, wells, flooded valley bottoms, or even via stream diversions or small dams.
