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

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

Crunch time’ for British's construction industry,

The Confederation of British Industry (CBI) has warned that the British construction industry is facing a crucial period, in which wafer-thin profit margins and an ageing workforce will clash with high demand for construction.

If the recent Sona announcements on infrastructure are anything to go by South Africa could soon have a high demand construction as well, how is the South African construction industry going to handle these challenges?


Crunch time’ for British's construction industry.


The demand for construction is marked with a widespread awareness of the need for sustainability in new homes, offices and transport infrastructure.


 The construction industry employs 2.3 million and contributes an estimated six per cent of UK GDP. Despite this, the industry is facing some concerns.

According to the report, the business model used in the construction industry is not fit for purpose, plagued with issues such as adversarial relationships between clients and contractors (as well as between businesses), unfair approaches to risk allocation and procurement, and a focus on price rather than value for money. The CBI also blames years of political uncertainty for diminishing confidence and investment in the sector and “creating an operating environment that is short-termist and unsustainable”.

The report recommends that both government and businesses have roles to play in resolving these issues, such as by discouraging single-stage procurement processes and instead ensuring that major projects plan an initial, non-competitive stage during the procurement process to identify and account for risks. It also recommends that businesses should be prepared to step away from contracts where the terms are too onerous or the price too low.

The CBI argues that tackling these outstanding issues will create a more financially sustainable construction sector less likely to run behind schedule and over budget and in a better position to invest more in training and technology.

“It is business’ investment in skills, technology and innovation that will rapidly improve the industry’s impact on the environment and create a safer, future-proofed built environment,” the report says.

Josh Hardie, deputy director-general of the CBI commented: “This is a crucial time for the construction industry with the demand for new, sustainable homes, offices and transport infrastructure on the rise, and all within the scope of rapidly improving the sector’s impact on the environment.”

“By fixing the foundations of the construction business model between clients and contractors, essential new investments in skills, tech and innovation are possible and we can unleash the full potential of the industry. Adversarial behaviours built up over many decades coupled with problematic approaches to risk allocation and procurement have resulted in a business model that too often remains short-termist and unsustainable.”
