As we can see from the table, extreme weather events associated with climate change have severe implications for marine water intrusion impacts and coastal flooding risks. These events highlight the urgent need to address climate change and develop effective adaptation strategies to protect vulnerable coastal communities.
Decline of Natural Defenses and Salinity Intrusion
Mangroves, an effective natural buffer against storm surges, are at risk due to flooding, deforestation, and increasing ocean surface temperature. The destruction of mangroves weakens the adaptive capacity of African coastlines and leads to an increase in vulnerable populations and losses in GDP.
Saltwater intrusion into inland coastal areas also negatively impacts river salinity, reducing the availability of clean water for drinking, irrigation, and freshwater fishing. This intrusion further weakens coastal zone management efforts and increases the risk of health issues for pregnant women and infants.
One of the key challenges in coastal zone management is the prevention of saltwater intrusion. Effective measures need to be implemented to maintain a healthy balance between freshwater and saltwater in coastal ecosystems. This requires comprehensive strategies that consider both natural and man-made solutions.
Table: Impacts of Declining Natural Defenses and Salinity Intrusion
| Impact | Description |
