Climate change causes water shortages, and these shortages create water insecurity for various stakeholders. Agriculture accounts for 60 to 70% of the available freshwater, and that freshwater is only 2.5% of the total planetary water.

Resources are dwindling in Sub-Saharan Africa and there is a need to increase the food production output with the same or less resources because the continental population is growing.

Where food is produced, water is overused owing to human operator dependence of current irrigation equipment, and this overuse results in economic losses (capital, revenue and virtual) for the farmer. While popular, scheduling can apply water when there already is water, making it inefficient. This results in puddling water, which gets the wheels of centre pivots stuck, resulting in capital loss. It also results in pests like aphids and weeds growing in favourable conditions and foraging on yields, resulting in revenue loss for the farmer. Groundwater can get contaminated by leaching of water with fertiliser and pesticides, resulting in ground water contamination, thus costing the property owner in future, apart from heat induced, avoidable evaporation.

Nosetsa addresses these challenges by removing operator dependence, once integrated with to the existing irrigation equipment. With the autonomy feature, the benefit is a digital brain that controls that irrigation equipment. It is remote, and does not require wiring andit avoids overuse, and prevent crop harm, avoids evaporation, and prevents leaching of water beyond the effective root depth of crops, while it uses solar power to reduce its energy requirements.
