MURANG'A, Kenya: Samuel Kinuthia knows how to make the most of technology. Using a technique called basin terracing, he has boosted his income at his farm in Murang'a county, and helped provide Kenyans as far away as Nairobi with better access to clean drinking water.
Kinuthia and a group of 300 farmers in Kiaruta village are turning hilly land into more productive farmland through basin terracing. It also reduces soil erosion, which can choke central Kenya's rivers and pollute drinking water.
