Emphasizes the much-needed multidisciplinary, transdisciplinary, and interdisciplinary approaches and efforts to deliver innovative, sustainable, and inclusive human settlements in cities. Remarkably, as urban areas grow, integrating advanced technologies with climateresponsive planning and inclusive governance frameworks is critical to ensuring long-term sustainability in infrastructure development and to creating intelligent, adaptable, and peoplecentered urban environments (Belizaire, 2025). In this vein, as many informal settlements and marginalized communities continue to experience energy poverty, unreliable electricity access, and dependence on polluting fuels such as paraffin and firewood, the decentralization of solar energy systems in addressing energy poverty and advancing energy justice in marginalized communities is fundamentally important (Mukwashi et al., 2025). To address energy poverty, innovative interventions should be explored to benefit marginalised communities in urban areas. Understanding that Municipal Solid Waste (MSW) management remains another critical environmental and social challenge for many cities in the African continent, renewable energy from solid waste could be an innovative solution to addressing not only the solid waste management crisis, but also the energy poverty in the marginalised communities (Obasi et al., 2025). Likewise, rural communities in the Global South countries are presently undergoing a radical transformation. Scholars like Sikhosana and Mashalaba (2025) identify the major drivers of rural-urban interaction and their implications for land use, governance, and socioeconomic organization in urbanizing rural regions, and eventually they conceptualized a novel framework for the governance and planning of rural-urban interfaces.In the South African context, the expansion of dormitory settlements on city peripheries remains a dominant feature of South Africa's post-apartheid urbanisation, and this phenomenon persistently reproduces the spatial and infrastructural inequalities of the apartheid era, resulting in the emergence of marginalised informal communities in cities (Mabotha, 2025). Sadly, these communities are faced with a housing crisis characterised by a growing backlog, unaffordability, and spatial inequality (Mvuyana & Matthews, 2025). As a result, there are divergent pathways to formalising informal settlements in South Africa, often leading to tensions between state-led urban modernisation and community-driven adaptation strategies (Kajiita & Kangéthe, 2025). To address these inequality challenges and housing backlogs in such human settlement settings, Boyce and Mbanga (2025) call for the professionalisation of the human settlements development sector, while Chumo et al. ( 2025) advocate for the profound principle of "leaving no one behind", as underpinned by the Sustainable Development Goals (SDGs), and acknowledge the inclusion of marginalised and vulnerable groups (MVGs) in all spheres. On this note, their study identified and characterised the MVGs, which included persons with disabilities, child-headed households, older persons, and refugees.Another phenomenon that threatens the sustainability and well-being of the urban population amid the urban expansion is the frequent seasonal flooding caused by climate change. To address the interactions between urban expansion and flood occurrence in Lagos, Nigeria, innovative strategies to enhance urban resilience were presented, including integrating climatetailored early warning systems and fostering active community participation in flood management (Dossa et al., 2025). Apart from natural disasters, man-made phenomena also pose hazards to the living conditions of communities in their localities. In this regard, the artisanal cobalt miners in the Democratic Republic of the Congo (DRC) confront exploitative working conditions, hazardous labor, and societal degradation; hence, the urgent need for transformative policies and legal frameworks that prioritise equitable resource governance, social justice, and human rights (Balyaminu et al., 2025).Therefore, it could be inferred that the realization of innovative technologies and solutions, sustainability, equity and social justice, and resilient infrastructure for sustainable cities and communities is cutting across jurisdictional boundaries and requires a multidisciplinary approach to solving these grand challenges. In this regard, broader stakeholder collaboration across inter-and intra-organisational systems, including researchers, policymakers, public and private practitioners, non-governmental organisations (NGOs), and communities, is a fundamental requirement for co-creating innovative solutions to build sustainable communities and cities and a better future for the next generation. As noted by Gourrier (2025), intentional resource coordination and sustained collaborative commitment can generate meaningful longterm effects on social and upward mobility within underserved urban communities.
