AB  - Irrigation development has been identified as one of the priority investment sectors in Ethiopia and the government has been implementing a number of efforts that enhance the planning and implementation of small-scale irrigation projects in the country. The aim was to identify the potential, feasibility and profitability of irrigation development for spices production mainly pepper in Jabi woreda of West-Gojjam, Amhara region. It has been observed that majority of the population, live in the rural area with crop production as the main livelihood option, arable land constitutes the largest portion of the ‘woreda’ land use type with cultivated land accounting for 49.8% (58,262 ha), uncultivable land 4.4% or 5,208 ha, natural forest 5.5% or 6,502 ha, bush land /scrubland and or natural pasture accounts 17.6% or 20,662 ha, settlement 9.3% or 10,931 ha and others account 13% or 15,389 ha.
