ENGLISH ABSTRACT: Agriculture is an industry that has seen a rapid increase in demand for technology innovation. With water being a limited resource, it is of utmost importance that it is well utilised. The agricultural sector is responsible for using more than 70% available freshwater and more than 40% of the global food supply is grown on irrigated croplands (Khokhar, 2017). Pivot irrigation systems experience a lot of water and power losses whilst in operation and there is a great need to reduce these losses. In this study an innovative irrigation system is designed that focuses on the reduction of water and power losses of pivot irrigations systems. The solution makes use of Internet of Things technology to determine the optimal irrigation schedules according to environmental conditions. A low-pressure irrigation sprayer (Powasave) is used to reduce the wind drift and evaporation losses. A commercialisation strategy for the solution is also developed. It was found that the solution will considerably reduce the power consumption and water losses of pivot irrigation systems, resulting in a more sustainable agricultural sector by increasing water and food security. AFRIKAANSE OPSOMMIMG: Die landbouindustrie ondervind ’n spoedige toename in die behoefte na tegnologiese innovasie. Aangesien water ’n beperkte hulpbron is, is dit van kardinale belang dat dit optimaal benut en aangewend word. Die landbousektor is verantwoordelik vir die gebruik van meer as 70% van vars water en meer as 40% van voedsel op ’n globale skaal word op besproeiide grond gekweek (Khokhar, 2017). Spilpunt besproeiingstelsels ondervind hoë water en krag verliese tydens werking en daar is ‘n groot behoefte om hierdie verliese te verminder. In hierdie studie word ’n innoverende besproeiingstelsel ontwikkel wat fokus op die vermindering van water en krag verliese van spilpunt besproeiingstelsels. Die innoverende oplossing maak gebruik van “Internet of Things” tegnologie om vas te stel wat die optimale besproeiingskedules is volgens die omgewingstoestande. ’n Lae-druk sproeier (Powasave) word gebruik om wind en verdampings verliese te verminder. ’n Kommersialiseringstrategie vir die innoverende oplossing is ook ontwikkel. Dit is bevind dat die innoverende oplossing die krag verbruik en water verliese van spilpunt besproeiingstelsels aansienlik sal verminder wat dus lei tot ’n meer volhoubare landbou sektor deur water en kos sekuriteit te verhoog.
