NEWS: Coastal wetlands are unable to adapt to the rate of sea-level rise and are constrained by infrastructure

Posted by on
Wetlands, precious ecosystems that shield coastlines, safeguard drinking water from saltwater contamination, and nourish diverse wildlife, face a dire threat from the accelerating pace of sea-level rise, driven by global warming. Wetlands have historically adapted to rising sea levels by expanding upward and inland. However, predictions indicate that the waterline will soon shift far too rapidly for wetlands to keep pace. Consequently, future decades may witness the tragic loss of these vital wetland ecosystems. Wetlands along coastlines have historically played valuable roles for people and wildlife, but are now facing the threat of sea-level rise. As temperatures rise, sea levels are rising at an accelerating rate, and wetlands are unable to keep pace by building upward and migrating inland. This is due to human-induced climate change and the burning of fossil fuels, which has warmed the oceans and melted glaciers. Sea levels are now rising at about 10 millimeters per year, and are

NEWS: World falling short of needed sustainable infrastructure investment

Posted by on

FIDIC's CEO, Dr. Nelson Ogunshakin, spoke at the Cesa Infrastructure Indaba. He said sustainable practices are being integrated into projects globally to achieve net zero by 2050.


He highlighted that $139-trillion must be directed towards sustainable infrastructure to bridge the gap and meet net-zero targets.

The world is currently underinvesting by $64-trillion, which means a doubling of infrastructure investment is needed between 2030 and 2050.

Ogunshakin also pointed out the infrastructure investment gap in Africa, with estimates ranging from $68-billion to $108-billion being needed every year.

In response, Cesa CEO Chris Campbell called for more sustainable infrastructure investment in South Africa, as it could be a cornerstone for economic growth and job creation. Only through collaboration between sectors can infrastructure challenges be addressed and sustainable growth fostered, he said.

Cesa president David Leukes added that inclusive infrastructure development must create opportunities for all, especially with South Africa’s high unemployment rate.
