The Spatial distribution of quarry stone mining sites in Igembe South Sub-county Meru County, Kenya

Abstract

The objective of this study was to develop a GIS-based spatial distribution of mining site patterns in order to identify risk-prone geo-locations in Meru County's Igembe South Sub County. Data was collected using PRA methodologies and processes, primary data was collected from participants' notes to detect mining-related problems, and an informal and formal survey and pair-wise assessment was used. There has been concern about the spatial distribution of mining in affected areas. The communities and mines in the Akachiu ward are as follows: Auki, Amwamba, Nceme, Kirindine, and Tiira. Information was obtained from 300 respondents. These issues were resolved by segmenting the target population and confirming field observations. Data were analysed using the nearest neighbour analysis method and descriptive means, median, and mode statistics. Results were then presented using tables, maps, graphs, and pie charts. Results established that mining activities have damaged land in Igembe South Sub-County, reducing food production and agricultural demands and polluting water supplies in the area, including contaminated streams. Pollution and noise are present in the area. It was affirmed that the residents know the environmental consequences of mining. In light of the County Government of Meru's efforts at restoration and intervention, such as re-afforestation, the mining companies and the County Government of Meru are reviewing their methods of operation and providing alternatives to the affected areas. Mining's environmental impact should be reduced by rethinking the environmental management strategy.
