Global warming, rising sea levels and rapidly growing cities are placing immense pressure on coastal cities, towns and subsistence communities. The U.S. Population Reference Bureau estimates that almost 6 billion people will be living within 200 kilometres of a coastline by 2025 – close to double the number in 2003. Population growth – along with sea level rise compounded by storm surges and increased rainfall intensity due to climate change – are the key reasons for the increase in coastal flooding and the degradation of our coastal regions and ecosystems today.

What has climate change got to do with increased groundwater salinity?
Rising sea levels due to climate change is affecting us more than we know
Sea level rise due to climate change is one of the contributing factors of salinity intrusion, particularly for shallow sandy aquifers in water stressed coastal areas. In many of such areas surface water salinity is additionally increased due to reduced upstream discharges and salinity can intrude both directly from the sea and from the surface waters. Furthermore, a temporarily rise in sea level can be caused by various acts of nature, such as tsunamis and hurricanes bringing about storm surges. Due to ongoing evaporation, the salt concentration of water in sandy aquifers have the potential to increase exponentially and eventually cause contamination or environmental problems.

How technology is helping professionals manage coastal erosion successfully
The coast is vulnerable to forces from the sea – and coastal protection and maintenance is an ongoing challenge.
Information and knowledge about wind, waves, depth conditions and sediment types is key in the decision-making process on how to protect the coasts. Continue reading “How technology is helping professionals manage coastal erosion successfully”
Five curious facts about climate change
And more in your copy of the guidelines to achieve sustainable adaptation
Higher temperatures and changes to other climate variables are leading to sea level rise as well as changes in wave climate, coastal environments, and the availability and quality of water for irrigation and other water demands. An increased hazard of extreme events such as storms, heavy rainfall and periods of drought and water scarcity is also expected. Continue reading “Five curious facts about climate change”
