A research report submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Science, 2018 / South Africa has implemented regular amendments to the Environmental Impact Assessment (EIA) regulations in an attempt to improve the effectiveness of the process. One way of evaluating effectiveness is to assess the quality of EIA reports submitted for decision-making. This study aimed to assess whether the amendments to the National Environmental Management Act (NEMA), (Act no 107, 1998) EIA regulations in 2014 have contributed to better EIA report quality in South Africa in comparison to the previous EIA system. As such, a sample of 26 EIA reports, 16 under the 2010 EIA regulations and 10 under the 2014 EIA regulations, were reviewed using an adapted version of the Lee and Colley review package. The findings of this research revealed that overall report quality improved under the 2014 EIA regulatory system compared to the 2010 system. Furthermore, an improvement in the 2014 EIA report quality indicates that the decision-making process is more well informed and holistic, which further indicates an improvement in effectiveness of the EIA process. Key amendments to the 2014 EIA regulations that have an influence on EIA report quality include appendix 2 which outlines the objective, scope and content of a scoping report, appendix 3 which outlines the objective, scope and content of an EIA report, appendix 4 which outlines the content of an EMPr, and appendix 6 which outlines the content of a specialist report. It is thus concluded that amendments to the EIA regulations have in fact influenced report quality. These findings differed from those of other studies undertaken on EIA quality under the 2006 EIA system in comparison to the 1997 EIA system.

Biodiversity and ecosystem service losses driven by land-use change are expected to intensify as a growing and more affluent global population requires more agricultural and forestry products, and teleconnections in the global economy lead to increasing remote environmental responsibility. By combining global biophysical and economic models, we show that, between the years 2000 and 2011, overall population and economic growth resulted in increasing total impacts on bird diversity and carbon sequestration globally, despite a reduction of land-use impacts per unit of gross domestic product (GDP). The exceptions were North America and Western Europe, where there was a reduction of forestry and agriculture impacts on nature accentuated by the 2007-2008 financial crisis. Biodiversity losses occurred predominantly in Central and Southern America, Africa and Asia with international trade an important and growing driver. In 2011, 33% of Central and Southern America and 26% of Africa's biodiversity impacts were driven by consumption in other world regions. Overall, cattle farming is the major driver of biodiversity loss, but oil seed production showed the largest increases in biodiversity impacts. Forestry activities exerted the highest impact on carbon sequestration, and also showed the largest increase in the 2000-2011 period. Our results suggest that to address the biodiversity crisis, governments should take an equitable approach recognizing remote responsibility, and promote a shift of economic development towards activities with low biodiversity impacts.

Ammonia as a transportation fuel offers a carbon-free, hydrogen rich energy source that emits no greenhouse gases in combustion, and has no global warming potential. Furthermore, it may be produced from any renewable energy resource, and is a strong option for long term sustainability. Ammonia also provides a pathway towards a hydrogen economy, which is the long term goal for environmental sustainability. This thesis investigates the feasibility of integrating ammonia as a combustion fuel, hydrogen carrier, heat recovery and working fluid, and for indirect engine cooling, within locomotive propulsion systems for nine novel ammonia-based configurations. Thermodynamic, environmental, and economic analyses are conducted for a typical modern diesel-fueled locomotive and the proposed ammonia configurations. The study comparatively assesses potential long term solutions for sustainable, clean rail transportation. From the modeled results, the proposed systems operating with 50% of required fuel energy replaced by ammonia have a reduction in diesel fuel consumption from 0.211 kg/s to less than 0.10 kg/s. This is associated with a reduction in GHG emissions of more than 8 tonnes CO2eq for a typical daily locomotive duty cycle for commuter operation. Criteria air contaminants are reduced to below upcoming Tier 3 emission levels for NOx and HC emissions, and meet current levels for PM emissions. In total, ten locomotive propulsion systems are investigated including the diesel-fueled locomotive baseline, and the performance gains are considered against economic factors for fuel and equipment costs in a comparative assessment.
