In Ghana’s Shama District, the rice fields of Whin Valley hold immense agricultural potential, providing food and livelihoods to the local community and beyond. But beneath this fertile land, a hidden story unfolds.
Three Mastercard Foundation Scholars from the University of Toronto set out to explore how local farming practices and nearby #Galamsey (illegal mining) activities may be impacting soil and community health.

Heavy Risks follows the three researchers; Emmanuella Avornyoh, Emmanuel Opkoku-Mensah and Martin Bartels as they conduct a preliminary quantitative risk assessment (PQRA), measuring heavy metal levels in the soil and laying the groundwork for deeper research on the potential health risks for farmers and residents.
Through stunning landscapes and candid conversations with local farmers, this documentary captures a journey about soil health, sustainability, and the community’s well-being.
