Public space initiatives (PSIs) in African cities can significantly promote health and social well-being, yet their implementation and impact are unknown across the continent. There is a substantial gap in literature on PSIs in African countries, with most studies concentrated in wealthier cities and lacking comprehensive assessments of long-term health impacts. The objective of this study was to synthesise evidence on the typology, location, features, and outcomes of these initiatives as well as the guiding principles that underlie their design and implementation. Employing a mixed-methods model, the study systematically reviews peer-reviewed and grey literature articles, focusing on the types, settings, and outcomes of PSIs. Data is analyzed using the CASP appraisal tool and thematic analysis. We analysed 47 studies, 15 of which were mixed methods, 22 qualitative and 10 quantitative. Sports accounted for 50% of initiatives. 30 of the 47 papers originated from South Africa. Communities viewed initiatives’ wellbeing impacts through social, economic, and ecological lenses, with health being but one dimension. The sustainability of initiatives was often limited by funding, historical marginalization, and competing land uses. Findings underscore the need for more comprehensive, long-term evaluations and cross-sector collaborations to sustain and enhance health-promoting public spaces in African cities.非洲城市中的公共空间倡议（Public Space Initiatives，PSIs）可显著促进民众健康与社会福祉，但在整个非洲大陆范围内，其实施情况与实际影响尚未得到充分探明。目前针对非洲国家公共空间倡议的研究存在显著缺口：现有研究大多集中于较富裕的城市，且缺乏对其长期健康影响的全面评估。本研究旨在系统整合现有证据，梳理这类倡议的类型、布局、特征与实施成效，以及支撑其设计与落地的核心原则。本研究采用混合研究方法，系统回顾了同行评议文献与灰色文献，重点聚焦公共空间倡议的类型、应用场景与实施成效。研究采用CASP评价工具与主题分析法对数据进行分析。本次共分析了47项研究，其中15项为混合研究、22项为定性研究、10项为定量研究。体育类公共空间倡议占比达50%，47项研究中有30项来自南非。社区从社会、经济与生态多维视角审视这类倡议的福祉影响，健康仅为其中一个维度。这类倡议的可持续性往往受限于资金匮乏、历史遗留的边缘化问题以及土地用途竞争。本研究结果凸显，为维持并优化非洲城市中促进健康的公共空间，亟需开展更全面的长期评估，并推动跨部门协作。
