Author(s): Addisu Asefa* and Hewan Tadesse
This paper reviews some of the factors affecting small-scale irrigation schemes in Ethiopia based on Environmental
factor, Social and Climate related factor, Irrigation scheduling and Siltation of the structure, lack of awareness
creation, Land factors and poor on farm irrigation water management. Ethiopian small-scale irrigation schemes were
often characterized by low water use efficiency as a result of poor on farm water management. There is water logging,
siltation of the structures, technical constraints, and inadequate awareness of irrigation water management, improper
irrigation scheduling techniques and operation and maintenance of irrigation facilities problem which affects
irrigation schemes. Sedimentation of structures reduces canal conveyance efficiency leading to risk of canal breach,
inadequacy and inequity in water distribution to crops. The Main gap.. View more»
