Rains/droughts have nothing to do with the lack of food in today's marketplace. Other economic forces and policies are more dangerous. I agree Uhuru's economic policies have been severe to Meru and other regions, but I disagree on the lack of Rain. Some areas NEVER rain in California for decades, but foods are here in plenty. You can never run out of milk, bread, flour, or any type of food from all over the world in the US, partly because of good roads, 24/7 electricity, industrialization, jobs, money in people's hands, and an Amazing supply chain, etc. I think poverty in Meru, UG, Nyanza, and most parts of Kenya is not because of rains; for the most part, I agree it is because of years of poor economic policies that have churned out poor people with no money in the last few decades. If people in Meru had money, companies and traders would be willing to supply food and all people's needs. Lack of money and a false sense of dependence on Rain for food is hurting Kenya. Energy (Petrol, electricity, etc.) is a big deal in the economy and needs to be addressed like yesterday. I think if petrol was reduced to 100 shillings a litter, and electricity be available in 90% of Meru, Rain could miss for decades, but people will not lack food.
A Chinese lady sells international foods in my neighborhood, selling about 5-7 items from Kenya. Unga, Ketepa, Royco, and a few things, but she never runs out because she has a consistent market. People in California have money because most have been paid every Friday or every other Friday for the last 100+years. With cash at hand, demand and supply forces work magic in that people will always go above and beyond to supply anything moneyed people need.
As long as people had plenty of money, other people called traders would always supply the area with anything. That is why desert Saudi Arabia and Gulf have plenty of food despite no rain. It boils down to money circulation, energy, and other factors except for rain/drought.
Opening the road network all over Kenya was the first start, though not complete; now we need to manufacture things, companies to hire people, electricity everywhere, and a lot of other interventions that put consistent money in people's pockets.
By the way, Nyanza has the most Rain, but the food supply is also a big problem. 4 in 10 people in Nyanza are hungry right now!
