The continual development of AI technologies has opened up potential for their use in various farming systems, including greenhouses
As agriculture continues to be one of the top revenue generating sectors in Africa, the popularity of greenhouse systems has seen a significant increase in recent years. Various fruits, vegetables and high-value crops are now being grown in specially designed greenhouse systems throughout the year, irrespective of weather conditions in the region.
Greenhouses are a mode of controlled environment cultivation that aim to create micro-climates that are favourable for producing crops during any time of the year. One of the main advantages of greenhouse systems is their ability to regulate temperature, maintaining optimal conditions in both hot and cold climates. In addition, greenhouses offer protection against pests and diseases, owing to their transparent structures clad with flexible materials that provides excellent ventilation. Moreover, they also optimise the use of other humidification and energy saving technologies that facilitate climate management, thereby boosting overall yield and production.
Since these indoor growing environments mostly require manual operation, installing automation technologies help in maintaining the desired internal environment with reduced reliance on farm labour. Also known as IoT smart greenhouses, these automated systems utilise a wide range of technologies including sensors responsible for heat control that modify in-house conditions based on the indoor climate. Moreover, computer automation software is often used to adjust humidity and venting, while Co2 monitors are used to regulate gas levels in the atmosphere.
Other notable control systems include programmes that automatically dispense pesticides in calculated amounts; equipment control systems that handle the movement of installed lights and planting equipment; fertigation management systems that automatically dispense water through water systems and lastly, drip irrigation systems that use soil sensors to monitor moisture levels in the soil.
