Methodologies used in assessing irrigation potential vary from one country to another.

The methods used to estimate the irrigation potential vary from country to country.

4330. % of irrigation potential equipped for irrigation (%) 4.185(1988) 9.036(2002)

4330. % of irrigation potential equipped for irrigation (%) 26I(2003)

With less than a third of the continent's potential using irrigation, most rural African communities are not tapping into their irrigation potential.

4330. % of irrigation potential equipped for irrigation (%) 12.99(1992) 16.01I(2002)

According to the African Development Bank, only 20% of the irrigation potential and about 6% of the hydropower potential has been developed in Sub-Saharan Africa.

(As it stands, less than 10% of Africa's irrigation potential is being used.)

Some regions have scope for much more irrigation, especially small-scale schemes.

At present, Ghanaian agriculture is rainfed, with only 4% of its irrigation potential being yet developed (Ghana, MOFA 2009).
