Although human interventions have influenced many coastal areas around the world, research has rarely assessed the environmental impacts of these anthropogenic perturbations. To understand the dominant coastal interventions in countries with tropical areas, this study established a baseline along the continental Caribbean coast of Colombia (approximates 1700 km), based on 29 types of human interventions cataloged via Google Earth images. In total, of the 2742 human interventions identified, the most common were low-density-settlements (n = 971), groins (n = 738), and luxury settlements with piers (n = 188). In addition, the study assessed the environmental impact of each type of intervention based on the extent, intensity, reversibility, and persistence of their effect on coastal processes, as well as their frequency of appearance in the study area. The three most impactful types of human intervention were equivalent to those with the highest frequency: a. Low-density settlements; b. Groins/Jetties; c. Luxury settlements with a pier. In addition, the highest values of environmental impact correspond to material extractions and infrastructure assets such as breakwaters and seawalls. None of these anthropogenic disturbances, however, were within the ten most impactful interventions identified in the study area. The socio-natural patterns of coastal development identified by this study can steer integrated environmental management in coastal tropical countries with rapid economic growth, diversity of human interventions and heterogeneous geographical distribution.

对人为干扰的哥伦比亚加勒比海地区的人类干预措施的评估

尽管人类干预已经影响了世界上许多沿海地区,但研究很少评估这些人为干扰的环境影响。为了了解热带地区国家的主要沿海干预措施,本研究基于通过Google Earth图像分类的29种人类干预措施,建立了哥伦比亚大陆加勒比海沿岸(约1700公里)的基线。总共确定了2742种人工干预措施,其中最常见的是低密度定居点(n = 971),腹股沟(n = 738)和带码头的豪华住区(n = 188)。此外,该研究根据其对沿海过程的影响的程度,强度,可逆性和持久性,评估了每种干预措施对环境的影响,以及它们在研究区域出现的频率。三种最有影响力的人工干预类型与频率最高的那些等效:低密度住区;b。腹股沟/码头;C。带码头的豪华住区。此外,最高的环境影响值对应于材料开采和基础设施资产,例如防波堤和海堤。但是,这些人为干扰均不在研究区域确定的十种最具影响力的干预措施之内。通过这项研究确定的沿海发展的社会自然模式可以指导沿海热带国家的综合环境管理,这些国家的经济发展迅速,人类干预措施的多样性和地理分布的多样性。三种最有影响力的人工干预类型与频率最高的那些等效:低密度住区;b。腹股沟/码头;C。带码头的豪华住区。此外,最高的环境影响值对应于材料开采和基础设施资产,例如防波堤和海堤。但是,这些人为干扰均不在研究区域确定的十种最具影响力的干预措施之内。通过这项研究确定的沿海发展的社会自然模式可以指导沿海热带国家的综合环境管理,这些国家的经济发展迅速,人类干预措施的多样性和地理分布的多样性。三种最有影响力的人工干预类型与频率最高的那些等效:低密度住区;b。腹股沟/码头;C。带码头的豪华住区。此外,最高的环境影响值对应于材料开采和基础设施资产,例如防波堤和海堤。但是,这些人为干扰均不在研究区域确定的十种最具影响力的干预措施之内。通过这项研究确定的沿海发展的社会自然模式可以指导沿海热带国家的综合环境管理,这些国家的经济发展迅速,人类干预措施的多样性和地理分布的多样性。最高的环境影响价值与材料开采和防波堤和海堤等基础设施资产相对应。然而,这些人为干扰均不在研究区域确定的十种最具影响力的干预措施之内。这项研究确定的沿海发展的社会自然模式可以指导沿海热带国家的综合环境管理,这些国家的经济发展迅速,人类干预措施的多样性和地理分布的多样性。最高的环境影响价值与材料开采和防波堤和海堤等基础设施资产相对应。但是,这些人为干扰均不在研究区域确定的十种最具影响力的干预措施之内。通过这项研究确定的沿海发展的社会自然模式可以指导沿海热带国家的综合环境管理,这些国家的经济发展迅速,人类干预措施的多样性和地理分布的多样性。
