The global health challenge of sedentary lifestyles and its repercussions for urban residents is evident, as shown in research studies in the United States of America and elsewhere. These studies revealed a concerning link between urban growth and heightened obesity rates among residents, underscoring the close relationship between built environments and health outcomes. Over half of the world’s population now lives in urban areas, and this proportion is expected to increase, extending this issue. There are many empirical studies indicating the link between nature and human health. The expansion of urban areas, characterised by sprawling layouts, concrete jungles, and limited accessibility to green spaces or recreational facilities, was identified as a major contributing factor leading to a decrease in physical activities in communities. Rwanda is undergoing continuous urbanisation, and considering the availability of urban green spaces is essential for alleviating the ecological problems created by this rapid urbanisation, especially in relation to improving residents’ well-being. Research shows clearly that we need nature in our surroundings. We need trees in our streets, plants in our gardens, and flowers on our balconies. We need nature as our neighbour all the time. We have a responsibility as humans to care for the environment in our cities. In exchange, the benefits to our health would be great. Urban green spaces are invaluable assets with immense potential to cultivate an active lifestyle among urban residents, thereby unlocking significant health and other benefits. These green areas offer opportunities for games and other physical activities, such as walking, jogging, cycling, or engaging in recreational sports, fostering a culture of movement and exercise within urban environments. By providing accessible and inviting spaces for outdoor activities, urban green areas contribute to improved cardiovascular health, reduced stress levels, and enhanced overall well-being. They also serve as communal hubs, encouraging social interactions and community engagement, creating a holistic approach to health that extends beyond individual well-being to encompass the broader social fabric of urban life. Embracing and expanding urban green spaces is not only an investment in the physical health of residents but also a strategic move towards creating vibrant, liveable cities that prioritise the holistic wellness of their inhabitants. The City of Kigali continues to push forward the green agenda through many interesting innovations. The Government of Rwanda (GoR), under its Economic Development and Poverty Reduction Strategy EDPRS (II), pioneered a vision of a Green City Concept. A 620-hectare site has been selected in Kinyinya, Gasabo District, Kigali City. The project aims to showcase the viability of green cities in Rwanda and elements that could be replicated in the development of secondary cities across the country with green technologies and innovations for green and climate-resilient urbanisation. The Nyandungu Eco Park is another space for residents and visitors to the city to explore and learn from nature and is part of Rwanda’s efforts to harness eco-tourism to restore biodiversity and conserve urban wetland ecosystems. The Green Growth and Climate Resilience Strategy (GGCRS) was first adopted in 2011 in Rwanda and has now been revised to align with Vision 2050, and it defines a development pathway for Rwanda that is climate resilient and harnesses green economic innovation. These aspirations will continue to be embedded in the revised GGCRS through the shared vision for Rwanda to be a developed, climate-resilient, and carbon-neutral economy by 2050. The green urban transition and its seamless integration into urban planning are of great importance in addressing pressing environmental concerns and fostering sustainable, resilient cities. Embracing a green urban transition involves prioritising eco-friendly practices, renewable energy sources, and the incorporation of green spaces within urban landscapes. Urban green space planning and design in Kigali city goes beyond aesthetic considerations of beautifying the city, accelerating economic development, and improving the ecological environment, it also exerts a profound influence on urban public health. Planning and designing green spaces within the city contributes to the overall well-being of residents by providing spaces for physical activity, stress reduction, and community interaction. These green areas serve as essential lungs for the city, purifying the air, mitigating heat, and fostering biodiversity. These areas also contribute to economic growth by enhancing the attractiveness of urban areas, attracting businesses, and increasing property values. As cities grapple with the challenges of rapid urbanisation, prioritising urban green spaces is a strategic investment in the holistic health and sustainability of urban communities.
