Box TL 1350 Tamale, Ghana [email protected] Abstract Recently, there has been an upsurge of small-scale mining activity in the Bolgatanga and Talensi-Nabdam districts of the Upper East Region following the discovery of gold bearing rocks around the Nangodi and Pelungu areas of the districts. This study attempts to relate population size and health hazards in the study area to the activity of small-scale mining. Based on the findings from field work it was deduced that the prevailing increase in population size and spread of communicable diseases as documented in the Regional Bio statistics service are related directly and indirectly to the activities of the small-scale mining.

Under this law, the Small-scale mining is currently seen globally as a Mining and Mineral Commission was made responsible source of subsistence for the poor, especially developing for the registration and supervision of small-scale miners countries, and as a determinant of environmental in the country (Hilson, 2001). degradation and resource depletion in areas where such Gold was mined during the colonial days within the precious minerals are mined (Barry, 1996; United Nangodi environs of the Talensi-Nabdam district, about Nations, 1996). The term small-scale gold mining refers 24 km from Bolgatanga, but was abandoned in the late to all formal and informal, manual and mechanized 1930s for political reasons. With the recent legalization mining that uses crude methods to extract gold from relating to small-scale mining activities under the Mining secondary and primary ore bodies (Heemskerk, 2002). and Mineral law (PNDC 153) in the early 1989, and the The activity of small-scale gold mining in Ghana is redundancy of mining workers in major mining said to have preceded the advent of large-scale industrial corporations in the south, notably, Ashanti Goldfields in gold mining especially in the Ashanti and Western the Ashanti Region and Tarkwa Mines in the Western Regions where both surface and alluvial gold was Region (Blench, 2006), small-scale mining activities exploited using varying crude techniques and methods became rampant in most communities in the Talensi- (Agbesinyale, 1990). Ironically, with the emergence of Nabdam district especially at Nangodi, Duusi, Pelungu, large-scale contemporary commercial gold mining Sekoti, Datuku, and Sheaga, and more recently, at industries shooting in, mostly from European countries, Sherigu in the Bolgatanga Municipality. There is currently the activities of small-scale mining were banned and one legalized small-scale underground mining made illegal with mining concessions exclusively given to concession in the study area located at Duusi, with metropolitan companies by the then colonial original statutory concession size of 72 km² (PNDCL 153) Governments. This was an action in an attempt to make in the 1990 which has been encroached in recent times. cheap labour supply more accessible to the large Illegal small-scale surface mining sites are located at expatriate mining companies and simultaneously to Nangodi, Sekoti and Sherigu (Bolgatanga District ensure that the monopoly position of these large Assembly Report, 2002). metropolitan mining companies was firmly affixed Small-scale mining, mostly in the Talensi-Nabdam regarding the prospecting, exploration, mining and district is highly subdivided with a hierarchy of workers marketing of gold and other precious minerals with different labour relations based on a combination of (Agbesinyale, 1990; Hilson, 2001).
