The document describes simulated groundwater table drawdown in the Karoo aquifer, noting that the zone of impact for the deeper fractured aquifer extends approximately 2 km north of the mine, though significant impacts are limited to areas immediately above the underground workings.

This document is a page from a groundwater model report by Yzermyn, discussing simulated groundwater table drawdown in the deep fractured Karoo aquifer and the potential impacts on springs and ecosystems.

The document argues that current proposed regulations for unconventional oil and gas (UOG) in South Africa are insufficient, particularly regarding the exclusion of coalbed methane (CBM) and inadequate groundwater protections. It recommends expanding definitions to include all stimulation techniques, implementing strict setback distances to protect sensitive aquifers and towns, and requiring long-term monitoring of decommissioned wells for up to 50 years to prevent contamination.

The Yzermyn Groundwater Model simulates the impact of mine workings on two aquifer systems. While the deeper fractured aquifer shows a zone of impact extending approximately 2 km downstream, significant drawdowns over 20m are limited to the area immediately above the mine. The model suggests that a steady-state cone of dewatering is an unlikely worst-case scenario given the 15-year mine life. However, groundwater-dependent ecosystems and springs within the shallow aquifer's dewatering zone, limited to site boundaries, may be negatively impacted or dry up.

This research paper examines the potential economic and environmental implications of hydraulic fracturing (fracking) for shale gas in South Africa, presenting three distinct scenarios to evaluate the trade-offs between economic growth and ecological preservation.

South Africa faces increasing vulnerability to climate extremes, including droughts in the west and intense rainfall in the east, with economic costs reaching billions of rand. Despite the Climate Change Act of 2024 mandating a national adaptation plan, implementation is lagging. The energy sector, responsible for nearly 80% of national emissions, is identified as the most critical area for mitigation through the upcoming Integrated Energy Plan (IEP). WWF proposes a 'People's Energy Plan' as a feasible path to net zero CO2 emissions by mid-century that supports developmental growth and employment.

The document examines the role of fossil gas in South Africa, detailing its current use in power generation and chemical feedstock, while arguing against its use as a 'bridge fuel'. It highlights the high global warming potential of methane leaks, the risk of stranded assets, and the availability of cheaper renewable alternatives combined with energy storage. The author concludes that South Africa should avoid new gas exploration and infrastructure to align with the 1.5°C warming limit and its own 2050 net-zero target.
