The Ghacem limestone quarry at Yongwa was established in May 2004. The quarry is located at Klo-Begoro in the Yilo Krobo District of the eastern region of Ghana, 92 km north of the Tema factory. The quarry site can be accessed by the main Somanya-Asesewa road and a dirt track linking the Bueyonye and the quarry site at Klo-Begoro, the nearest settlement.
The limestone will be extracted until 2013 to provide the Ghacem cement plants with limestone. The concession covers an area of about 81.45 ha, while the current project site occupies an area of about 46 ha. In 2011 Ghacem started a rehabilitation project. The aims of this project are to reestablish a natural scenery and thereby reclaim the environmental impact. For this purpose, a tree-nursery was built-up to deliver seedlings and assist natural succession. Furthermore the stakeholder-communities are involved in the rehabilitation project to meet their demand for an appropriate after-use of the quarry area.
The project area is located in the high temperature and rainfall zone, within the forest zone of Ghana. It is characterized by two main raining seasons, notably the wet and dry seasons. The mean temperature ranges between 22°C and 30°C .The state of flora within the Klo-Begoro concession area has undergone tremendous change over the years due to human activities. Generally the vegetation consists of elephant grass, shrubs and scattered trees (Acacia spp.), Neem-tree (Azadirachta indica), and silk cotton tree (Ceiba pentandra). Also widely spread is the castor oil plant (Ricinus communis).
