It is extremely important to monitor local seismic activity before fracking starts to avoid causing harm.
A vulnerability map could help assess the risks associated with fracking and groundwater which around 300 towns depend on in South Africa's Karoo.
South Africa's Karoo region potentially holds shale gas that could transform the energy economy of the country. But given the uncertainties around exploration what's the next logical step?
Why protesters should think about putting their feet up.
South Africa has been considering shale gas development in the Karoo region. The gas, will be expensive to explore and extract, will be used as part of the country's energy mix.
Gas buried in the Northern Territory's Velkerri Shale was produced in a "slime world" that existed nearly a billion years before the first complex life on Earth evolved.
Shale gas holds considerable advantages. But there are still a number of uncertainties around whether South Africa is ready for such a bold step.
Research shows people don't trust planning decisions if it seems central government or energy companies have had too much influence.
The government promises cash for communities that accept fracking, but cannot know whether it can keep that promise or not.
Councillors are caught in the crossfire between government, industry, protestors and locals.
Woodside's deferral of its floating gas project in Western Australia is just the latest blow low oil prices have dealt the industry.
There's a bunfight about whether local or national government should call the shots when it comes to fracking.
UK's decision to close coal power plants is really a statement of the obvious, and does nothing to answer the problem of what to do afterwards.
Different states and countries with shale gas can benefit from the mistakes made by other regions that rushed into fracking. Here’s one state’s plan.
Fracking fluids in Marcellus shale have contaminated groundwater but new study finds that the source is likely from surface spills, not leaks from underground wells.
South Africa's Karoo area has potential for gas deposits and other mineral deposits like nickel and copper.
Those against shale gas extraction have scored a couple of wins in the north-west of England, but industry-government-researcher collusion may yet win the day.
With wind braced for more cutbacks, government backing of nuclear and fracking will end in tears.
Fracking presents a better alternative to coal mining. Finding a way to produce the gas economically is the first challenge to getting fracking underway.
Europe was supposed to be big business for fracking companies, but so far not so good. So what's going wrong?
