Step-by-step explanation:
According to Wambugu, African growers need new technology in order to improve agricultural yields and address food insecurity. Despite the availability of technologies like hybrid crops and fertilizers, adoption rates have been persistently low in many African countries due to barriers such as limited access to seed and fertilizer. By implementing new technology, such as composting, crop diversification, organic pesticide production, seed multiplication, and agro-forestry, farmers in Africa can increase their ability to feed their families over the long term.
