Urban Governance, 2025 (Scopus)
The ecosocial transition advocates for an approach that is ecocentric, transdisciplinary, resource-efficient, socially inclusive, equitable, and democratic. Over the past decade, digital participatory platforms (DPPs) have gained prominence in supporting ecosocial transitions by addressing chronic and wicked problems affecting both specific territories and the planet as a whole. However, fragmented overviews and biases in socio-spatial and socio-technical contexts have left a notable knowledge gap between technological advancements and research on their affordances in urban planning and design ecosystems. This study examines how DPPs are introduced and conceptualized in literature. It explores distinguishing characteristics, emerging trends, and key success factors of geospatial DPPs through the lens of the collective intelligence (CI) framework. Following the PRISMA protocol, a systematic review was conducted across Scopus, Google Scholar, and public repositories, identifying 312 platforms worldwide. The coded descriptions of platforms were analyzed using content analysis, network mapping, and AI-powered clustering to reveal underlying patterns and relationships. Our findings reveal a diverse spectrum of technological features, human-computer interactions, and engagement levels across DPPs. However, geographical distribution and effective institutional adoption remain limited. Nearly half of the examined geospatial platforms rely on one-way information flow focused on data aggregation, while co-creation platforms increasingly adopt advanced technologies such as gamified urban simulators, extended realities, and networked sentient technologies to foster interaction and co-design capabilities. The insights from this comprehensive review contribute to a better understanding of DPPs for ecosocial transition, emphasizing key design aspects such as accessibility, transparency, transferability, user-friendliness, follow-up mechanisms, and continuous feedback. Given the complexity of urban governance and the challenges commonly highlighted in the literature regarding participatory approaches, DPPs are predominantly deployed to complement—rather than replace—existing top-down and technocratic planning frameworks. Strengthening the concept of participants as co-researchers within action research remains essential for fostering long-term systemic impact and stakeholder empowerment.
