Drip Irrigation. Extension Manual By ALIN - EA, 2002. 36 pp. Kshs 250 (Kenya) US$ 5 (Ethiopia, Uganda & Tanzania) / US$ 8 Euro 7.75 elsewhere
A good manual doesn t need to be bulky. The Arid Lands Information Network Eastern Africa (ALIN EA) proves this with their 36-page booklet on drip irrigation. This water application method consists of hollow tapes with holes at regular intervals. These holes are positioned nearby the crop s root area, allowing the water to be directed exactly to where it has to be, without losing it through surface runoff or seepage in the sub-soil. For a long time this method was expensive and was associated with large-scale industrialised cultivation. This manual presents drip irrigation as being suitable at a small-scale too (e.g., for watering vegetables during the dry season). Technically, all that is required is a bucket and irrigation tape. The bucket should be placed at an elevation of 1 m, high enough to ensure enough water pressure in the tapes and low enough to be able to fill the bucket manually. From beneath the bucket 30 m of drip tape lead the water to the crops. All in all, a straightforward text for extension workers, indicating the necessary steps in training farmers to use this method and avoid mistakes made in the past. The booklet is illustrated with attractive drawings and colour photos, adding value to the text. Drip Irrigation.
