In Kenya's Laikipia County, where temperatures can soar to 30 degrees Celsius, a local building technology is making a significant impact on housing conditions.The use of compressed earth blocks (CEB) is helping homes remain cooler while also supporting education, creating jobs, and improving the livelihoods of community residents.
