As for the implications of climate change on the coastal zones, the main challenge is the rise in sea level and sea surface temperature due to the rise in temperatures. Sea levels have been on the rise in the Mediterranean basin at an average of 20mm every year leading to an increase of 30-60cm in the next 30 years. This can potentially affect coastal natural reserves in addition to coastal irrigated agriculture. Also, coastal flooding, coastal erosion, degradation of coastal ecosystems, sea water intrusion and loss of sand beaches are potential risks resulting from rising sea levels. It must be noted that these potential risks can affect the tourism sector if not considered in the long run, especially bearing in mind that Lebanon is reliant on its tourism industry.
