I am an agricultural engineer specialized in water management. I worked on the production and vulgarization of ecological charcoal in 2014. From 2017 to 2019, I have carried out a research study on biochar (biological charcoal), using it for soil improvement and drinking water treatment. I produced a biochar water filter prototype that I'm now using in my house, taking note of some aspects that enable me to improve the filter. I'm engaged in a Ph.D. research on the water and energy demand management in irrigation systems on the Bamboutos Mont.
