Soil Pollution and Remediation
Ein Kapitel aus dem Buch Soil Pollution and Remediation

Abstract

Gold mining in Ghana poses serious environmental and socioeconomic challenges, creating a soulless habitat for human and animal species, despite the existence of legal and regulatory frameworks. This study utilized policy analysis, participatory netmapping, expert interviews, and focus group discussions to delve into the experiences of after-mined land reclamation strategies from four communities in the Ashanti region of Ghana. Complementarily, a survey of 100 households was also conducted. The study identified revegetation, soil management, landfilling, community participation, and integrated water management as the primary methods of reclamation. The findings reveal that there are instances of failed or unsuccessful reclamation. The lower rate of reclamation efforts in the studied communities was attributed to weak policies, a lack of education and training, limited enforcement resources, financial and logistical constraints, and key stakeholders that have been neglected in the mining and reclamation value chain. There should be an increase in capacity development for the communities. Further, all key stakeholders involved in the reclamation network must coordinate to ensure an efficient reclamation process. This coordination requires transparency, quality communication, and accommodating diverse views to achieve after-mined land reclamation success.
