摘要

COVID-19大流行向我们展示了城市在应对这一现象时是多么脆弱。绿地的缺乏、高污染水平和人口过剩导致了城市热岛效应的增加,并被证明是病毒传播的完美因素,这种病毒可能永远地改变了我们的生活居住方式。对非正式社区的居民来说,其后果更为严重,因为这加剧了与经济不稳定和粮食和水安全程度低有关的现有问题。本文建议使用基于自然的解决方案来缓解和适应气候变化,并增加非正式住区的水获取。研究集中于分析两种技术,蓝绿屋顶和雨花园,为每一种技术开发一个原型。考虑到自发住区的自建特点,这些模块由居民使用可回收材料建造。这些低技术含量的策略改善了室内热舒适性,促进了过滤雨水的储存供家庭使用,并通过家庭规模种植提供了负担得起的食物。在边缘化社区实施这些解决办法还可以使居民有能力面对与全球变暖有关的挑战,例如强降水产生的径流,并改善卫生条件以防止疾病传播。

Water security: the “new normality” of informal settlements. Nature-Based Solutions as sustainable mitigation and adaptation strategies
The COVID-19 pandemic showed us how fragile cities are when dealing with this phenomenon. The lack of green areas, high pollution levels, and human overpopulation contributed to the increase of the urban heat island effect and proved to be the perfect ingredients for the spread of the virus that changed, perhaps forever, our ways of living inhabiting. The consequences were even more dramatic for the inhabitants of informal neighbourhoods, as these exacerbated existing problems related to economic instability and low food and water security. This paper proposes using Nature-Based Solutions to mitigate and adapt to climate change and increase access to water in informal settlements. The research study focused on analysing two technologies, the Blue-Green roof and Rain Garden, developing a prototype for each one. Considering that the practice of self-building characterises spontaneous settlements, the modules were conceived to be built by theinhabitants using recycled materials. These low-tech strategies improve indoor thermal comfort, facilitate thestorage of filtered rainwater for domestic use and provide access to affordable food through domestic scalecultivation. Implementing these solutions in marginalised neighbourhoods could also empower residents to face challenges related to Global Warming, such as runoffs generated by heavy precipitations, and improve hygienic conditions to prevent the spread of diseases.
