Analyses of crop water use and environmental performance of small private irrigation along the white Volta basin of Northern Ghana

Small private irrigation (SPI) is a farmer-initiated which has the potential to increase contribution of overall sector global food security. However, there no much information about these systems for effective policies regulation. This study compared resource use productivities and environmental impacts SPI those government-led scheme (GIS) in Northern Ghana. The results showed that land productivity was higher than GIS. Productivity per unit cultivated area 2571.00 US$/ha under while GIS 676.00 US$/ha. Output command also two times GIS; 1113.00 respectively. For water productivity, output supply 0.33 US$/m3 0.08US$/m3 respectively consumed by ET 0.60 0.06 implied schemes performed better with attributed yields selection high valued crops farmers SPI. both system types at time this did not cause significant deterioration bodies surrounding environment as biochemical oxygen demand (BOD) values nearby were less 3.0–5.0 mg/l, considered acceptable levels drinking World Health Organisation (WHO) salinity within limits (<750 μS/cm).
