ABSTRACT

This study considers climate impacts and environmental challenges (flooding and sea-level rise) in one of the coastal informal settlements in Lagos, Nigeria. A mix of methods was used to generate data. First, 14 residents, selected through purposive sampling, were interviewed. A survey (sample size = 300) of residents was conducted as a follow-up to the interviews. To elicit information on spatio-temporal dimensions, GIS-based mapping showed change in land use/cover from 1990 to 2020 and simulates impacts with 0.5 m, 1 m, 1.5 m and 2 m sea level rise scenarios. The results illuminate negative corollaries at the intersection of informal urbanisation and climate change in coastal settings. Flood-related impacts on the built and natural environment were significant. Climate adaption and resilience will need to involve restoring the decimated natural ecosystem and integration of indigenous systems in the study area and similar low-income coastal urban communities.

摘要

本研究考虑了尼日利亚拉各斯沿海非正式定居点之一的气候影响和环境挑战（洪水和海平面上升）。使用了多种方法来生成数据。首先，对通过有目的抽样选择的 14 名居民进行了访谈。作为访谈的后续行动，对居民进行了调查（样本量 = 300）。为了获取有关时空维度的信息，基于 GIS 的制图显示了 1990 年至 2020 年土地利用/覆盖的变化，并模拟了海平面上升 0.5 m、1 m、1.5 m 和 2 m 情景的影响。结果阐明了沿海地区非正规城市化和气候变化交汇处的负面推论。洪水对建筑和自然环境的影响是显着的。
