Experts Call for Innovative Repurposing of Abandoned Mining Sites at DAAD-Alumni Conference in Kumasi

At the recent DAAD-Alumni Conference held at the CSIR-Soil Research Institute in Kumasi, scientists and researchers gathered to advocate for the innovative repurposing of abandoned mining concessions across Ghana. This call to action comes in response to the alarming environmental degradation caused by illegal mining activities, which continue to plague these once-productive lands. As illegal miners continue to exploit abandoned sites left by large-scale companies, experts warn that restoring these degraded lands could take a staggering 300 years. While the government and mining corporations strive to mitigate the environmental impact, researchers are calling for a more inclusive approach that explores alternative uses for these lands beyond mere reclamation.

Dr. Jones Mantey, a Strategic Mine Consultant, spoke at the conference about the challenges faced with reclamation efforts. “Some community members opposed a plan by a mining company to convert an abandoned site into aquaculture. They argued that they are miners, not fishermen, and wouldn’t want a fishing hub. This created challenges. If security isn’t tight at abandoned sites, it creates problems,” he noted.

Dr. Mantey proposes transforming these abandoned sites into energy hubs or recreational areas. He pointed out that backfilling dug pits can be difficult, suggesting that converting them into water resources or hydro dams could provide economically, socially, and environmentally friendly alternatives.

Dr. Albert Mensah, a senior research scientist at the Soil Research Institute of the Council for Scientific and Industrial Research (CSIR-SRI) and program coordinator for the DAAD Alumni event, emphasized the challenges of phytoremediation. “Phytoremediation is difficult. Since these mining companies are businesses, they are not ready to wait for these plants to absorb the toxic chemicals, as it takes a long time,” he stated.

Dr. Collins Tay, Director at the Soil Research Institute, underscored the necessity for government commitment in restoring natural resources adversely impacted by illegal mining.

“Once the miners are licensed, they must set aside funds for restoration right from the start of production,” he advised.

The discussions at the conference reflect a growing recognition of the need to balance economic interests with environmental sustainability, as experts seek to find effective solutions to the challenges posed by mining in Ghana.

Professor Jörg Rinklebe, the keynote speaker, delivered a presentation cataloguing the various works he has undertaken over the years. Professor Rinklebe is among the top 2% of scientists worldwide.

In his presentation, Prof. Rinklebe recounted the numerous projects he is leading as the principal investigator across Europe, Asia, America, and Africa.

He described the effectiveness of phytoremediation technologies in removing contaminants from polluted soils and water. He concluded that restoring the pristine or original state through phytoremediation could take between 10,000 and 100,000 years.

The DAAD-Alumni Conference brought together local and international researchers and stakeholders to discuss the impacts of both large-scale and artisanal gold mining on the environment and to propose practical solutions for sustainable practices.

ALSEMAC PROJECT

ALSEMAC Project Team Engages CSIR-Soil Research Institute in Strategic Collaboration Visit

The ALSEMAC Project Team has completed a two-day strategic visit to the CSIR-Soil Research Institute (CSIR-SRI) in Kumasi, Ghana, as part of its ongoing efforts to strengthen partnerships in research and innovation for sustainable food systems. This engagement, which took place from 4 to 5 June, brought together leading scientists and researchers from both institutions to explore collaborative opportunities aimed at enhancing food security and promoting environmental sustainability. The ALSEMAC (Advancing Local Solutions for Environmentally Managed and Agroecologically Conscious Agriculture) project is committed to promoting safe, healthy, and sustainable food production systems. Its mission closely aligns with CSIR-SRI’s mandate to advance soil science and organic fertilisation, transforming organic residues into products of high agronomic value while reducing the carbon footprint.

During the two-day interaction, the teams shared insights on research priorities, discussed mutual areas of interest, and identified pathways for collaboration on projects concerning soil health, agroecological practices, climate-smart agriculture, and sustainable land use. The visit included lab tours, field demonstrations, and technical presentations from CSIR-SRI scientists, providing the ALSEMAC team with a firsthand view of the Institute’s cutting-edge work.

Dr. Dugan explained a point to the ALESMAC team.

Dr Angel Jose Fernández, Professor of Toxicology at the La Laguna University in Tenerife, Canary Islands, Spain, and the Team Lead for the ALSEMAC Project, emphasized the importance of partnerships in tackling the complex challenges facing food systems.

“This collaboration with CSIR-SRI represents a major step toward integrating scientific expertise and local knowledge to develop resilient agricultural practices that not only boost productivity but also safeguard public health and the environment,” he said.

Dr Emmanuel Dugan, a senior research scientist and project lead at CSIR-SRI, expressed optimism about the partnership’s potential impact, noting that the synergy between the two institutions could lead to transformative outcomes in Ghana and throughout the West African region. The visit concluded with a commitment from both parties to develop a formal framework for collaboration, which will include joint research initiatives, knowledge exchange Programmes, and capacity-building activities.

Other members of the ALSEMAC project team included Ricardo Didz from the Environmental Analysis Department at the Technological Institute of the Canary Islands and Dr Maria Del Nar Bernal Suarez, who is also from the same institute.
