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

How will Africa develop infrastructure for its growing population?

Posted by on

Africa's anticipated 2050 population, will be almost twice as much as the existing population and would need a well-developed infrastructure to thrive. The existing infrastructure will not meet the needs of this growing population.

How does Africa create infrastructure that meets the needs of a growing population?

Africa needs new infrastructure models to meet growing population needs: report

A new report has urged Africa with its development partners to design new business models for infrastructure development to meet the needs of the growing population on the continent.

The report launched by the Development Center of the Organization for Economic Cooperation and Development (OECD) and the Africa Center for Economic Transformation (ACET) said the continent would be home to about 2.5 billion people by 2050.

This anticipated population, which will be almost twice as many as the existing population, the report pointed out, would need a well-developed infrastructure to thrive.

In the face of this growing population, the report said the existing business models for project development had failed to meet the development needs of Africa.

The report listed institutional capacity constraints as well as complex regulatory and technical standards as some of the major causes of this delay.

It, therefore, called for a change in this model to reach the development goals enshrined in the African Union’s Agenda 2063, as well as strengthening regional and local value chains and create more jobs for urban and rural populations.

“African governments need to design new ways of managing such projects, by making infrastructure investment faster and less burdensome,” it recommended.

The report proposed two overarching mechanisms to accelerate the preparation, funding, and implementation of infrastructure projects on the continent.

“Expand the quality labeling system of the Program for Infrastructure Development in Africa to recognize quality infrastructure, and create a platform to enhance real-time peer learning and the sharing of good practices among African infrastructure professionals,” it urged.
