This work investigates the autonomous adaptive capacity of populations in flood-prone areas in the city of Belem (state of Para) in the Amazon region of Brazil. Autonomous adaptive measures are behaviors that the population adopts without explicit planning or the assistance of either institutions, professionals, or both, all of which are focused on protecting themselves from risks. This research focuses near the part of superficial drainage channels, which is divided into five areas. Visits to the study area and interviews with residents allowed to identify urban typologies and autonomous adaptive constructive techniques, as well as the relationship between these forms of adaptation and the socioeconomic conditions of the population. The main results are associated with the main motivations, information and knowledge that support flood adaptation strategies and the consequences of their success or failure in Amazonian cities. Some of them indicates that autonomous flood adaptation measures were not provided with professional technical assistance or externally financed; the measures are associated with structural modifications (e.g., raise the level of the properties and improve the building) and non-structural modifications (e.g., shims). Some of the conclusions are associated with sources of information; community recognition of flood adaptation methods; motivation to the measures implemented autonomously; consequence to the urban planning and people internal migration, and the difficulties to identify and characterize an adaptation measure as proactive or reactive in recurrent flood cycles in Amazonian cities.

这项工作调查了巴西亚马逊地区贝伦市（帕拉州）易受洪灾地区人口的自主适应能力。自主适应措施是人们在没有明确计划或机构，专业人士或两者都不提供帮助的情况下采取的行为，所有这些行为均致力于保护自己免受风险侵害。这项研究集中在浅层排水通道附近，该区域分为五个区域。参观研究区并与居民进行访谈可以确定城市类型和自主的适应性建设性技术，以及这些适应形式与人口社会经济状况之间的关系。主要结果与主要动机有关，支持洪水适应策略的信息和知识，以及它们在亚马孙城市中的成功或失败的后果。他们中的一些人指出，没有提供专业技术援助或没有外部资助的自主防洪措施；这些措施与结构修改（例如，提高性能水平并改善建筑物）和非结构修改（例如，垫片）相关。一些结论与信息来源有关。社区对洪水适应方法的认可；主动采取措施的动力；造成城市规划和人们内部迁徙的后果，以及难以识别适应性措施并将其描述为亚马逊城市经常性洪水周期中的主动或被动措施。
