  1. 1.7AFAR REGION’S IRRIGATION PRACTICE Shimelis Faye

  2. Population and Climate • The Region is Divided in to five administrative zone & thirty one woredas and the population is estimated to be about 3M • Annual precipitation ranges from 150- 500mm • Average daily temperature is 45oC when high and 20 -25oC when low

  3. Livelihoods • Pastoral & Agro-Pastoralist

  4. Agricultural Practice • Rain fed Agriculture • Irrigated Agriculture

  5. Rain fed Agriculture • Cannot fully support/ in adequate/ for crop growth hence, irr. Is a must in the region

  6. Irrigated Agriculture • About 20 surface irr. schemes were constructed on perennial rivers to cultivate about 1700 ha of land and two schemes were constructed to irrigate 290 ha of land by diverting Ephemeral rivers

  7. Irr.Ag. Cntd…. • Tali and Alena irrigation projects were built in 2007/2008 to utilize Ephemeral rivers Tali and Gulina respectively. • Tali was to cultivate 90ha of land but couldn’t achieve the goal last season b/c ( i.e. only farmers near the headwork could cultivate their land) • gates at the headwork were not operational • Community participation is weak • Land preparation is not made favorable to trap the flood( i.e. bunds were not made ready) • The headwork has got silted up by one day flood

  8. Irr.Ag. Cntd…. • Tali irr. project headwork

  9. Irr.Ag. Cntd…. • Alena irr. Project is where there is active community participation and some of the proposed land cultivated using the flood • Since the headwork is masonry weir • Gate operation during high flood was not correct and scouring of the field and silting up of the weir up to the rim.

  10. Irr.Dev. Cntd…. • The undefined nature of the river banks • The susceptibility of the soil to erosion are other threat of the region in general

  11. Opportunities for spate and other irr. In the region • There are many perennial &Ephemeral rivers flowing from the neighboring high lands • Ground water is also one of the water resource which can be used • Perennial rivers are:- • More than 30 perennial Rivers are flowing in the region including Awash and Kesem - Kebena

  12. Opportunities Cntd…… • Ephemeral Rivers:- • Logia, Yalo Gulina, Tali and many other descending from the mountains of Amhara and Tigray

  13. Opportunities Cntd…… • Because of shortage of rain to fully grow crops irrigation is a must in general and the presence of many seasonal rivers flowing in the region in particular makes flood utilization ideal • Need of the community to participate in irrigated agriculture both for food and fodder production since rain couldn’t support their livelihood

  14. Some of the schemes and the problems in picture Dalifage IP whose bank is widened beyond the weir crest length

  15. Pictures Cntd…… Dalifage
