What is ocean acidification?
Ocean acidification is an effect of atmospheric carbon dioxide entering the ocean, lowering the water’s pH and increasing its acidity levels. High levels of carbon dioxide in the atmosphere is largely an effect of human activities, such as deforestation for agriculture or fuel, but it is mainly caused by the burning of fossil fuels – coal, oil and gas – to produce large amounts of concentrated energy at a relatively low cost.

Ecosystem services are defined as services provided by nature to humans. This straightforward definition suggests a passive role for humans as receivers of the outputs of nature. However, there is also an active role for people to play in providing these services. Continue reading “How can humans contribute to ecosystem services?”
The rapid pace of development in coastal areas often comes at an environmental and ecological cost, with the accelerated loss of coastal nearshore habitats such as seagrass meadows and mangrove forests. However, the presence of these nearshore coastal habitats play an important role in the maintenance of resilience of coastal cities and populations. They confer resilience via ecosystem services such as carbon sequestration, moderation of natural hazards and nutrient cycling. There is a recognised and urgent need to stem the loss of these valuable habitats in balance with infrastructure development and economic needs.

How to recover good environmental status with new marine habitats
Marine structures – such as piers, windmills and bridges – typically have a bad name when it comes to their effects on the environment. But did you know that their existence could impact marine environments positively too? Continue reading “Creating positive environmental impacts with artificial reefs”
Rapid coastal development, combined with population growth and global industrialisation, is placing coastal and marine environments under increasing pressure. New ports and harbours, coastal defence and climate change adaptation measures, as well as land reclamation and dredging works are imperative in order to support our existing and future economy.
