The only way to shore up the KES is to reduce imports. We import everything including Toilet Paper. When I shop at Nakumatt, I am shocked at what people buy.
Construction: There is a local firm (I think in Kisumu) called Flamingo Tiles. Also Sai Raj Tiles. Let's buy LOCAL tiles not imported tiles just so we can say "Italian" or "South African". They provide jobs to KENYAN clay mines, KPLC, etc.
Food: Stop with the (zero local content) imported cereals. They are often sugary. Go for locally manufactured Weetabix which mixes local & imported wheat & is manufactured in Nairobi. Weetabix provides local jobs including KENYAN farmers, carton manufacturers, etc.
Fuel: This is hard to change but let's encourage local sources. There is a bio-ethanol fuel I saw on telly. I might get that vs LPG. How about making 'charcoal' from other sources like coffee husks or maize stalks or wood dust?
Water: I avoid buying bottled water. A little trick a friend showed me. I will fill 75% of my bottle (or those durable reusable sports bottles) at home then leave it in the freezer. When I go out, I fill the remainder 25% with a bit of squash/quencher. I have a cold drink that remains cold as the ice slowly melts.
Shoes: That's a tough one since Bata does not have a great range. Even it imports many of the shoes it sells. I try though!
Clothes: It drives me nuts that Kenya is an exporter of textiles under AGOA (& even to Europe) yet we import clothes from China, India & South Africa. We need to create a SENSIBLE 'national dress' (not that silly stuff akina awori modeled) that should be 'copyrighted' for manufacture only in Kenya. We need to get back to Bespoke Tailoring for men using good materials & local tailors. These suits/shirts fit well & last longer.
Farming/Food: Let's embrace the TRADITIONAL foods like Njahi, Cassava, etc. Why not eat healthier Sweet Potatoes instead of adding sugar to everything? Let's move away from maize (imported from Central America) to what is better suited for Kenya's climate/land.
Furniture: We are obsessed by the (cheaper) East Asian furniture. Let's go for a more rustic look made by local artisans. My uncle had his cushions/sofas re-done & they look FANTASTIC. They cost 50% of the cost of replacing the sofas.
