CONCLUSIONS AND RECOMMENDATIONS - Sustainable Irrigation Development in the White Volta Sub-Basin - page 223

Third, some of the emergent irrigation techologies found in ste study area
have been described for the first time (Ofosu et al., 2010)
Fourth, the study also established that irrigation grew at a rate of 5% per
year. If irrigation in the White Volta sub-basin would continue to grow at
this rate, by 2025 irrigation would reduce streamflow from the White Volta
sub-basin by 35%, which equals a 9% reduction in inflow into Lake Volta.
The study established that the socio-economic benefits of upstream
developments far outweigh the benefits foregone in electricity production.at
Akosombo.
Finally, the case of endogenous irrigation development in the White Volta
clearly shows that irrigation policies must focus on empowering local farmers
to become entrepreneurs.
