In the face of numerous research efforts and policy interventions, housing the urban poor in a suitable manner has been a persistent challenge across the world. This prevailing difficulty calls for more resourcefulness in addressing affordable housing (AH) provision. To achieve this, this study thoroughly investigated the informal housing strategies of the urban poor, examining their informal housing solutions along the three main components of housing supply value chain (HSVC) - housing finance, land acquisition and housing construction. The methodology was semi-structured interviews of 40 randomly selected respondents from 5 strata of largest slums in Lagos, Nigeria. Following thematic, content, descriptive and deductive analyses of data, findings show that there are insightful lessons within the informal housing strategies of the urban poor that can inform suitable approaches to AH provision. Findings are that the urban poor are actively involved in trade unionism, microfinance institutions and cooperative societies as AH finance strategies within their informal means. The urban poor resolve their desperate housing needs through self-help incremental housing, cheap rental housing among others. Findings show that the urban poor needs shelter, which alternative housing and rental housing provide more affordably than homeownership. Insights are provided in this study on how these informal strategies of the urban poor can influence HSVC for effective affordable housing provision approaches. If these strategies inform policies with deliberate efforts made to modify and institutionalise the approaches, suitability of AH provision can be improved. Findings from this study are informative for future pro-poor housing studies. Recommendations are that informal strategies across the entire HSVC identified in this study can be modified and incorporated into housing policies towards making cities of developing economies more sustainable and inclusive.

发展中经济体有效提供经济适用住房：尼日利亚拉各斯非正规住房战略的演绎分析

面对大量的研究工作和政策干预，以适当的方式为城市贫民提供住房一直是世界各地面临的持续挑战。这一普遍存在的困难要求我们在解决经济适用房（AH）的供应问题上更加足智多谋。为了实现这一目标，本研究深入调查了城市贫民的非正规住房策略，沿着住房供应价值链（HSVC）的三个主要组成部分（住房融资、土地征用和住房建设）审视他们的非正规住房解决方案。该方法是对来自尼日利亚拉各斯最大贫民窟 5 个阶层的 40 名受访者进行半结构化访谈。对数据进行主题、内容、描述性和演绎分析后，研究结果表明，城市贫民的非正规住房战略中存在深刻的教训，可以为住房供应的适当方法提供参考。调查结果表明，城市贫民积极参与工会、小额信贷机构和合作社，作为非正规途径的 AH 融资策略。城市贫困人口通过自助增量住房、廉租住房等方式解决迫切的住房需求。调查结果表明，城市贫民需要住房，而替代性住房和租赁住房比拥有住房更便宜。本研究提供了关于城市贫民的这些非正式策略如何影响 HSVC 的有效经济适用住房提供方法的见解。如果这些策略为政策提供信息，并刻意努力修改这些方法并将其制度化，则可以提高 AH 规定的适用性。这项研究的结果为未来的扶贫住房研究提供了信息。建议修改本研究中确定的整个 HSVC 的非正式战略并将其纳入住房政策，以使发展中经济体的城市更​​具可持续性和包容性。
