This article seeks to interrogate the advantages and disadvantages of beneficiation law for Botswana’s mining industry and its implications for foreign investment protection. Furthermore, it argues that the enactment of beneficiation law could stimulate economic growth and development in Botswana. On a proper analysis of the potential of beneficiation law it seems plain that it may facilitate the integration, of among others, the cutting and polishing segments through the backward and forward linkages in the entire diamond value chain to move Botswana diamond industry a step further as a new and emerging jewellery manufacturing and retail center in order to derive maximum returns from the rough diamond production. Quite clearly, cutting and polishing of diamonds in Botswana is bound to promote employment which in turn will promote demand for goods and services that would have a positive impact on economic growth in Botswana.  The paper concludes that on a balance, the opportunities accruable from the enactment of this law far outweigh the downsides and will not in any way scare investors away as some have perceived it.

Illicit Activity

In Liberia’s diamond sector, the dynamics of the BOPC Group show how diamond mines remain vulnerable to takeover long after war has ended. From mining to taxing to exporting, West African governments have long struggled to control the supply of diamonds within their territories and the physical and social isolation of diamond mining areas has meant that they effectively govern themselves. This geographical buffer gives extralegal groups room to grow, develop organizational structures, and build up local networks of influence. Yet their claims to legitimacy are ultimately rooted in whether their mining activities are classified as legal or illegal, formal or informal, legitimate or illegitimate. Characterizing artisanal diamond mining as an “illicit” activity also feeds into the international community’s desire to sanitize the industry—even at the expense of miners’ livelihoods. This chapter demonstrates that these categorizations are not simply claims of law, but claims of power.

Geochemical risk is caused by the release of hazardous chemicals to the earth surface. Primary diamond deposits are located in difficult mining and geological conditions. They represent natural geochemical anomalies associated with the mineral composition of rocks and groundwater, which contain a number of impurity elements with high toxic properties (Tl, Di, As, Cd, Hg), and increased concentrations of heavy metals (Cu, Zn, Pb, Ti, V and others). The paper presents the physical-geographical and mining-geological conditions of the diamondiferous region, where three large mining and processing divisions operate: Udachninsky, Aikhalsky and Nyurbinsky. pH, organic matter (humus), total nitrogen, and physical clay were identified in the study samples, by using potentiometric, photoelectric colorimetric, spectrophotometric methods, and pipette method for particle size analysis. Gross and mobile forms of trace elements were determined by atomic absorption and emission spectrometry. The groups of elements were identified that determined the natural and man-made anomalies. The accumulation of Cr, Ni, and Co determines the influence of kimberlite magmatism in general. Cu, Sr, and Li are accumulated in the soils of the Daldyn-Alakit diamond-bearing region. Increased concentrations of Mn and Cu are typical in the soils of the Sredne-Markhinsky diamond-bearing region. An assessment of the ecological and geochemical state of the study areas was carried out according to the indicator of total pollution (Zc), which is the sum of the excess of the concentration coefficients of chemical elements accumulating in anomalies. Areas of pollution and zones of the greatest risk are localized, which occupy up to 75% of the total area of industrial sites. They confined to quarry-dump complexes and to areas of impact of tailing dumps of processing plants.

ABSTRACTAlthough conflict in Zimbabwe's diamond mining sector has recently received much international scrutiny, very little research has examined conflict in Zimbabwe's gold mining sector. This article analyses how a nationwide crackdown calledOperation Chikorokoza Chapera(‘No More Illegal Mining’) affected – and ‘disciplined’ – livelihoods in profound ways in both licensed and unlicensed gold mining regions. Drawing on interviews conducted between 2006 and 2013 with artisanal miners in the Insiza, Umzingwani and Kadoma areas as well as miners who crossed the border to Mozambique, the study reveals how a highly politicised crackdown led to uneven consequences. The analysis highlights both structural and physical violence, with more than 25,000 miners and traders arrested between 2006 and 2009 and more than 9,000 still imprisoned in 2013. Situating the crackdown within evolving political and economic interests, the study contributes to an understanding of how simplified discourses on ‘eradicating illegal mining’ mislead and mask power dynamics, while policing activities transform patterns of resource control. The study also emphasises that conceptualisations of the crackdown's legacy should carefully consider the agency of artisanal miners' associations, which, in some cases, have been actively seeking to resist coercive policies and rebuild livelihoods in the aftermath ofOperation Chikorokoza Chapera.

Management And Conservation

The Chapada Diamantina National Park (CDNP) was created in the midst of a densely populated area, and significant sections of the reserve are still undergoing processes of natural regeneration after intensive diamond mining activities were initiated in the mid-1800's. An up-to-date vegetation map was needed in order to indicate the types and distribution of regional vegetation assemblages in an easily interpretable manner and at an appropriate planning scale that could be easily consulted by decision makers and other interested groups at all levels of conservation (and development) planning. A vegetation map of the Chapada Diamantina National Park, and the areas immediately surrounding it, was prepared that: 1) delimits, describes, and maps the regional vegetation assemblages; 2) provides an indication of the degree of conservation of the mapped vegetation; 3) develops this information in a format that facilitates continued updating and revision as more information becomes available, enabling the monitoring of the evolution of the Park lands, and; 4) presents this information in a manner that can be easily interpreted and used for planning, management and conservation purposes. The resulting vegetation map revealed intensive anthropogenic disturbances in forested, savanna, and semi-arid areas subjected to intensive agricultural use outside of the Park boundaries. The National Park lands are generally well preserved but burning has replaced formerly extensive forest areas with open sedge meadows. In spite of intensive modification of the regional vegetation, two well preserved areas with high priority for conservation efforts beyond the National Park limits were identified and characterized. The vegetation mapping of the park itself can aid in the preparation of its management plan and in the reformulation of the existing boundaries of that reserve.
