Professional knowledge

Consequences of Sea Level Rise :

Nature in coastal areasInvasive species, sea or land migrationDykes and low land areas near the coastNumber of storms and increasing intensity – 1/100 years storm each year?Salt water intrusion in coastal groundwater reservoirsTemperature PrecipitationDrought or too much water

Threads to be met now:

Flooding of cities, houses, vulnerable nature etc in lowlandsRoads and transport, sewer and drainsTourist industry Water level in rivers and estuaries Invasive insectsNew pesticidesDrinking water resourcesEtcEtcEtc
