This study examined the environmental and social effects of large‐scale mining in Chingola, Zambia. Data was collected through semi‐structured interviews with 164 residents living close to Zambia's largest open pit mine, key informants and desk analysis of secondary data. Quantitative data was analysed using the chi‐square test, one sample T‐test and two sample Z‐proportions test, while qualitative data was analysed using content analysis. Results show that the residents reported being most affected by sulphur dioxide air emissions and noise pollution due to the proximity of the copper smelter and heavy moving machinery to their residences. The residents received domestic water containing rust and copper ore particles from the water utility company which draws raw water from the mine. Although the mine was a source of employment for locals, over 4,000 jobs (representing a 33% decrease) have been lost over a period of 4 years, negatively affecting the local economy. Mine management attributed the job losses to high production costs and mechanization of mining processes. The residents perceived the job losses to have led to crime, alcohol abuse and prostitution among youths as well as a general increase in poverty levels. Analysis of air emissions data from the mine found elevated levels of dust, cadmium, copper and lead pollutants. Key informants from Nchanga Mine reported implementing bioremediation to reduce soil contamination by the heavy metals and recycling SO2 to produce sulphuric acid. The study recommends an increase in social corporate responsibility from the mine management to ensure residents derive more substantive benefits from their proximity to the mine.

“…Previously, some economic tree species that were logged from this ecological zone include Canarium schweinfurtii (black pear), Pentaclethra macrophylla (oil bean), Garcinia kola (bitter kola), Vitex doniana (black plum). Milicia excelsa (Iroko) Khaya ivorensis (mahogany) Nauclea diderrichii (Opepe) (Ogbonna et al, 2015). These species have disappeared as none was present in this current study.…”

“…To our knowledge, there are no detailed studies documenting the plant species inventories of coal mining sites in Nigeria, especially Enugu (the Nigerian Coal City that used to be home to Iva Valley, Ogbete, Onyeama, and Okpara mines (Sikakwe et al, 2015;Agbalagba and Uzo, 2018). Nonetheless, there is an environmental impact assessment (EIA) report which highlighted the effects of coal mining activities on biodiversity, especially on economic tree species (e.g., Khaya ivorensis and Milicia excelsa) in Akwueke and Iva Valley communities within the Enugu Coal City (Ogbonna et al, 2015). Other previous studies focused instead of floral composition on the geoenvironmental characteristics of the Okpara, Onyeama, and Ribadu coal mine sites (Sikakwe et al, 2015;Sikakwe, 2017).…”

The remnant floral diversity of a naturally reclaimed area proximal to an abandoned mine was assessed. The coal mine site, the Incident zone (IZ) and an unsullied site, the Control zone (CZ), were sampled. Using a 5 m2 quadrat, the floristic composition was determined by the occurrence, distribution analysis, and species diversity indices. The study revealed a degraded vegetation type and recorded a total of 60 species, 53 genera and 27 families. Both the IZ and CZ shared 26.67% species similarity, while 36.67% are were unique to each zone. Five species were dominant (Ageratum conyzoides, Panicum maximum, Calopogonium mucunoides, Chromolaena odorata). While the dominant genera vary between IZ (Borreria, Dioscorea, Ipomoea, and Phyllanthus) and CZ (Desmodium, Euphorbia, and Ipomoea), Asteraceae and Poaceae were the dominant families in both zones. Forbs were the most dominant life forms in both zones; Cyclosorus sp. and Adiantum sp. were only found on the IZ, whereas, Kyllinga erecta and Mariscus alternifolius were exclusive to the CZ. Our results reflect that species composition and vegetation paradigm in the study area could be influenced by coal mining, farming, infrastructural installations and climate. Hence, we suggest future studies to investigate how the species adapt to the environment. Although most of the species encountered belonged to lower-risk conservation, the conservation of the species to this area is imperative.

Centrochelys sulcata, the African Spurred Tortoise (Family Testudinidae) is one of the largest terrestrial chelonians in the world, the largest extant continental tortoise, and the largest tortoise in Africa. Males are larger than females, and may exceed 100 kg in body mass, with a straight carapace length of up to 86.0 cm in males and 57.8 cm in females, and a curved carapace length reaching 101.0 cm in males and 67.0 cm in females. The species has a wide geographic distribution across the arid savannahs of the Sahelian regions of sub-Saharan Africa, but with many gaps in its range, and reaches the southern tip of the Arabian Peninsula. The sex ratio is nearly equal and sexual maturity is reached at 10-15 years. The species is especially linked to habitat with periodic or intermittent streams and rivers, locally called kori in the Sahelian regions. In addition, African Spurred Tortoises can be found on slopes and hills, in particular on stabilized dunes, and sporadically in flat areas with semi-deciduous shrublands and high grasses. Cattle grazing has a negative effect on the presence of this species, especially when grazing areas are created with seasonal fires. The species is mostly herbivorous, but can feed on carrion on occasion and on garbage in the surroundings of human settlements. Males are highly territorial, with larger males winning sexual combats. The population density is among the lowest that has been observed so far in terrestrial chelonians. The species makes extensive use of deep and long burrows (up to 15 m long), occasionally used by more than one individual, and above-ground activity is mainly concentrated in the early morning hours and during the wet season (August). Reproduction is also seasonal, with matings occurring primarily in September to April. Nesting occurs from September to May, during which 2-3 clutches of 14-40 eggs (average egg ca. 52 x 44 mm, 55 g) are laid. The species is declining rapidly due to a plethora of reasons, including habitat loss, exploitation for eggs and meat as well as for the international pet trade, and the effects of climate change, but since it is easy to breed in captivity and is frequently bred by local communities, there is significant potential for reintroduction programs, some of which have already been initiated in Senegal.distribution. -
