On a global scale, as of 2012, 324 million hectares were equipped for irrigation, with 85 percent of it being irrigated, corresponding to about 21 percent of all cultivated land and claiming 44 percent of the global crop production (FAO 2016a, and FAO 2016b). Figure 2. Area equipped with irrigation as percentage of cultivated area (2012) (FAO 2016) The role of irrigation in the alleviation of poverty has been the focus of many international communities and groups in the recent years. More investment is going into the modernization of the existing systems to improve the efficiency of water use and increase the crop production. This approach can directly benefit farmers and alleviate poverty. Irrigation is dependent on water and rainfall is the main natural source to provide that water. As population growth and demand for water use in irrigation rapidly increases, struggle for a secure water supply will become more difficult to administer, especially in arid parts of the world. Large arid areas with absolute water scarcity which affects millions of people, many of whom are poor and underprivileged. Irrigation in South Africa is currently practiced on 1 600 000 hectares and it uses 60% of the available water. Large areas of the Republic of South Africa are subject to hot and dry climatic conditions, high evaporation and a low and intermittent rainfall, where optimal crop production is not possible without the addition of plant-available water by means of irrigation.Although some rains fell in many parts of South Africa the past January, it is still in the grip of a drought that effects all of us and it impact on food security. In Figure 3, the percentage rainfall that occurred the past 4 months is shown, and one can see that many parts of South Africa received well below 50% of its normal rainfall.
