“…The study reported high activity concentration of 40 K in the studied cattle organs. However, there were limitations of the study design and presentation that raise questions concerning the utility of the findings (Aliyu et al 2015a). For instance, the very small sample size (only five cows) and limited controls likely biased the results of the study.…”

The tin mining activities in the suburbs of Jos, Plateau State, Nigeria, have resulted in technical enhancement of the natural background radiation as well as higher activity concentrations of primordial radionuclides in the topsoil of mining sites and their environs. Several studies have considered the radiological human health risks of the mining activity; however, to our knowledge no documented study has investigated the radiological impacts on biota. Hence, an attempt is made to assess potential hazards using published data from the literature and the ERICA Tool. This paper considers the effects of mining and milling on terrestrial organisms like shrubs, large mammals, small burrowing mammals, birds (duck), arthropods (earth worm), grasses, and herbs. The dose rates and risk quotients to these organisms are computed using conservative values for activity concentrations of natural radionuclides reported in Bitsichi and Bukuru mining areas. The results suggest that grasses, herbs, lichens, bryophytes and shrubs receive total dose rates that are of potential concern. The effects of dose rates to specific indicator species of interest are highlighted and discussed. We conclude that further investigation and proper regulations should be set in place in order to reduce the risk posed by the tin mining activity on biota. This paper also presents a brief overview of the impact of mineral mining on biota based on documented literature for other countries.

“…Venetia mines (South Africa) and Orapa mines (Botswana), and iron ore extraction in Guinea, phosphate mines (Togo), Uranium mines (Niger), etc. In many cases, these activities have resulted in negative environmental impacts including polluted freshwater resources that have become toxic and unsafe for drinking and fishing, as well as pollution of wetlands and soils rendering them unsafe for agriculture (Sracek et al, 2012;Aliyu et al, 2015). This is particularly evident in the severe impact of oil spills from drilling activities in the Niger Delta (Nigeria) on the livelihoods of local communities.…”

Rapidly changing landscapes and disturbance regimes in the Global South impact the viability of conservation planning. Although conservation planning processes benefit from reliable multi-scale and multi-temporal data on landscape changes, this is not widely understood. In this paper, the authors examine landscape change dynamics and disturbance regimes in the Global South and discuss the methodological needs of characterizing pattern-process relationships of landscape disturbance to facilitate effective conservation planning. For example, geospatial analysis of Nairobi-Namanga Road, in the Kaputei Plains of Kenya, was used to highlight impacts of road infrastructure on wooded grassland and open grasslands, on wildlife migration corridors and livelihoods. The authors discuss how integration of geospatial technologies and landscape ecology metrics could enhance conservation planning and decision-making in the Global South. The benefits of coupling the decision-making process with stakeholder engagements and nature-based solutions to ensure viable conservation of biodiversity were also discussed.

The activity concentrations of 40K, 232Th, and 238U in five different organs of bovine meat commonly eaten by the Nigerian populace were measured using gamma ray spectrometry. The meat samples were collected from a Government owned abattoir at Ikpoba slope, Benin City. The essence of the study was to estimate the internal radiation dose incurred by a population due to the ingestion of radionuclides from meat consumption. The mean absorbed dose rate was 12.60 ± 1.51 nGy h−1, which is far lower than the recommended value of 55 nGy h−1. The AACED obtained in this study differs for each organ, thereby making the threshold consumption rate different, but the mean dose, 0.171 ± 0.07 mSv yr−1, is below the 0.3 mSv yr−1 reported to be the recommended average value. The mean threshold consumption rate for meat intake for the samples under study was calculated to be 107.5 ± 6.22 kg yr–1. Thus, this study has contributed to the body of knowledge and data that can lead to the formulation of regulations related to radiological healthcare in the study area.
