Just 15% of coastal regions remain intact, study finds

Only 15% of global coastal regions remain intact, according to researchers at the University of Queensland. 

The researchers mapped the impact of human-caused pressures on coastal regions to identify those that are already highly degraded and those that remain intact. 

The research team discovered that, of the 15.5% of coastal areas that remain intact as of 2013, Canada was responsible for the largest expanse of the coastal region that stood intact. 

Brooke Williams, from UQ’s School of Earth and Environmental Sciences, said the findings, which have been compiled into a free and useable dataset, provide valuable insights into humanity’s widespread impacts on Earth’s precious coastal ecosystems.

‘Coastal regions contain high levels of biodiversity and are relied upon by millions of people for ecosystem services such as flood and storm protection,’ Brooke Williams said.

‘Our results show that we need to act quickly and decisively if we hope to conserve those coastal regions that remain intact and restore those that are heavily degraded, especially if we’re going to mitigate the effects of climate change.

‘The rate at which these regions are degrading poses massive threats to not only coastal species and habitats, but also to the health, safety and economic security of countless people who live or rely on coastal regions around the world.’

Dr. Amelia Wenger added: ‘While we already knew how important it is to protect biodiversity and ecosystem services in these coastal regions, being able to clearly see how rapidly and how far this degradation has spread, is truly eye-opening.

‘Understanding why coastal ecosystems are under pressure can help us design and implement more targeted management strategies, and hopefully slow this degradation down and even turn it around.

‘We’re urging governments and custodians of these environments to proactively conserve the valuable remaining intact coastal regions that they are responsible for, while restoring those that are degraded.

‘We think our dataset will be a vital tool in achieving that ambition, which is why we’re making it publicly available and free to use.’

That climate change tax scam ain’t going to wash friend.
