红树林是肯尼亚沿海地区重要的生态系统。它们生产对人类社会具有环境、生态和经济重要性的商品和服务。然而，红树林受到人为干扰的持续压力。一个特别令人关注的问题是清理红树林区域，以开垦土地用于其他用途，如水产养殖、制盐、农业和住房。在恩戈梅尼和卡拉瓦之间，大约有10,000公顷的红树林被清理出来用于制盐，而在拉穆，近100公顷的红树林被莫科威喷气式海机建造过程中挖出的沉积物所杀死。在恩戈梅尼，100公顷的红树林面积已被改为水产养殖。在加齐湾，大约100公顷的红树林被砍伐成薪材，在蒙巴萨的马库帕溪，10公顷的红树林因石油污染而死亡。因此，损失的总面积为10310公顷，约占红树林总面积的20%。本文讨论了肯尼亚海岸的森林砍伐、红树林改作其他土地用途和红树林沼泽的污染，呼吁可持续利用，并制定了实现可持续利用的政府政策。
Mangroves form important ecosystems in Kenya's coastal areas. They produce goods and services that are of environmental, ecological and economic importance to human society. However, mangroves are under continuing pressure from anthropogenic disturbances. A particular concern has been the clearing of mangrove areas to reclaim land for other uses such as aquaculture, Salt manufacture, agriculture and housing. About 10 000 ha of mangrove areas have been cleared for salt manufacture between Ngomeni and Karawa, while in Lamu, close to 100 ha of mangrove forest was killed by dredged-up sediment that was deposited during the construction of the Mokowe sea jet. 100 ha of mangrove area have been converted for aquaculture at Ngomeni. At Gazi Bay, about 100 ha of mangrove forests was cleared for fuelwood and in Makupa Creek, Mombasa, 10 ha of mangroves died due to oil pollution. The total area lost is therefore 10 3 10 ha which represents about 20% of the total mangrove forest.In this paper, deforestation, conversion of mangrove areas for other land uses and pollution of mangrove swamps on the Kenyan coast are discussed and a call for sustainable use, and the government policies that will enable this, is made.
