Rhagolwg
I am a PhD student & technician working on a global GCRF funded project investigating the effect of agricultural plastic use on food security and sustainable development in developing countries. My research within this project focuses on the effect, fate, and legacy of agricultural mulch film use on the agroecosystem. I am interested in the chemical degradation of plastic, changes to soil microbial communities and general effects on soil & crop health.
