| Abstract from DBPedia | Coastal management is defence against flooding and erosion, and techniques that stop erosion to claim lands. Protection against rising sea levels in the 21st century is crucial, as sea level rise accelerates due to climate change. Changes in sea level damage beaches and coastal systems are expected to rise at an increasing rate, causing coastal sediments to be disturbed by tidal energy. Coastal zones occupy less than 15% of the Earth's land area, while they host more than 40% of the world population. Nearly 1.2 billion people live within 100 km of shoreline and 100 m of sea level, with an average density 3 times higher than the global average for population. With three-quarters of the world population expected to reside in the coastal zone by 2025, human activities originating from this small land area will impose heavy pressure on coasts. Coastal zones contain rich resources to produce goods and services and are home to most commercial and industrial activities.海岸管理（かいがんかんり、英語: Coastal management） は陸地の洪水や侵食を防ぐこと、およびその手法。沿岸地帯は地球上の最大15%近くを占めており、地球人口の45%を抱えている。14億人近くの人々が沿岸から100km以内で海抜100m以下の場所に居住し、この地域の人口密度は全球の人口密度より3倍も高く、気候変動による海面上昇によって21世紀ではその重要性が増している。 (Source: http://dbpedia.org/resource/Coastal_management) |
