To attract greater levels of foreign direct investment into their gold-mining sectors, many mineral-rich countries in sub-Saharan Africa have been willing to overlook serious instances of mining company non-compliance with environmental standards. These lapses in regulatory oversight and enforcement have led to high levels of pollution in many mining communities. The likelihood is high that the risk of pollution-related sicknesses will necessitate increasingly high healthcare expenditures in...

To attract greater levels of foreign direct investment into their gold mining sectors, many mineral-rich countries in sub-Saharan Africa have been willing to overlook serious instances of mining company non-compliance with environmental standards. These lapses in regulatory oversight and enforcement have led to high levels of pollution in many mining communities. The likelihood is high that the risk of pollution-related sicknesses, such as skin infections, upper and lower respiratory...

This paper links a utility theoretic model based on internalized norms with the results from a novel public good experiment in Ghana. The results indicate that, on average, people are motivated by condition- al cooperation or reciprocity: i.e. they want to contribute more if others have contributed more in the previous round. We also find evidence of learning, in the sense that people’s contributions decrease over time even when others’ contributions are held constant. Moreover, our results...

Within the last century, the global average temperature increased by about 1 °C and this rate of increase may accelerate over the course of the 21st century [1]. Although estimates of climate change are based on projections and probabilistic assessments, ample evidence exists that climate change impacts are likely to become more profound in this century, particularly if mitigation policies are absent or inadequate [1,2]. It has been argued that, relative to keeping the warming at 2 °C or...

Maize is the primary food staple in southern Africa, and 50 percent of the total maize output in the area is produced in South Africa, where maize constitutes approximately 70 percent of grain production and covers 60 percent of the country's cropping area. Climate change could have a significant impact on South African maize production. The scientific community has established that the temperature in South Africa increased significantly between 1960 and 2003 (by 0.13 degrees Celsius), and...

Human activities such as fossil fuel burning and deforestation have significantly increased the atmospheric concentration of greenhouse gases (GHG) leading to global climate change. Global climate change and its associated weather extremes pose considerable challenges worldwide, and mitigating the adverse impacts of climate change is a high priority for the international community. To reduce global emissions and curb the threat of climate change, many countries are participating in carbon...

A linear public good experiment has been employed to investigate strategic behaviour in pollution abatement among African climate decision-makers. The experiment consisted of three groups of which Group 1 did not receive any treatments, and Groups 2 and 3 received one and two treatments, respectively. We found that the untreated group (baseline) polluted more than the two treated groups, while there was no statistically significant difference between the pollution abatement of the two...
