Great visit and thanks for sharing this. I'd like to know more about the findings of this research. I am working on related issues here in my country Sierra Leone. Interestingly I studied in Japan likewise- at the International Christian University (ICU) Tokyo. My African Youth on Mining and Environment (AYME) is doing advocacy for sustainable land reclamation after mines closure. We can connect if that is okay with you. 

Hello! Perhaps you'd be interested in the Planning for Closure 2018 congress that will take place on Nov. 7-9 in Santiago Chile . see more at Gecamin.com/PlanningforClosure . The program includes experiences and learnings from across the mining world. Regards!

Thanks for your interest in this research and invitation.
