Pivot Irrigation is beginning to 'crop-up' around Ghana. Using the water pressure, that is also feeding the irrigation nozzles, to drive the wheels, and with a centre pivot that allows the gantry to spin around, enables a large circle of crops flourish. There are new challenges in ploughing techniques and water filtration, as well as a new set of maintenance skills to learn. Already popular in the southern and Eastern parts of Africa, this technology is now filtering into West Africa, and we all wait to see the long term success and, most probably, adaptations that it will bring.
