Marshalltown High School students Yessenia Alvarez Zamora and Landon Stanley were selected to attend the 2022 World Food Prize Global Youth Institute, where they presented their research on addressing food insecurity.
In presenting her research, Alvarez Zamora suggested using biochar – a charcoal-like material made from agricultural waste products – as an alternative to commercial fertilizers on small farms in Mexico.
Stanley’s research focused on solar heating as a means of water disinfection in Angola. Solar water disinfection uses energy from the sun to destroy harmful microbes. The combination of heat and ultraviolet radiation works to help prevent water-borne illnesses.
Both students recently featured on Iowa Public Radio’s Talk of Iowa program – give them a listen here!
Thank you to Landon Stanley and Yessenia Alvarez Zamora for representing MHS at this year’s Global Youth Institute!
