Introduction

Urban areas, increasingly recognized as critical ecological landscapes, demand a multifaceted approach to ensure sustainability and enhance human well-being. A global review emphasizes that urban green infrastructure is pivotal for maintaining biodiversity, highlighting that thoughtfully planned green spacesâ??including parks, green roofs, and street treesâ??are essential for supporting diverse species within city limits [1].

The crucial insight here is that the strategic design and interconnectedness of these green elements are fundamental for fostering ecological resilience, moving beyond mere isolated patches to create a cohesive network that supports urban nature. This interconnectedness allows for greater species movement and genetic exchange, strengthening the overall urban ecosystem. Beyond biodiversity, urban ecosystem services are intricately linked to human quality of life. A comprehensive review reveals that natural functions within citiesâ??such as providing clean air and water, regulating temperature, and offering vital recreational spacesâ??yield substantial benefits that profoundly improve residents' well-being [2].

Understanding and actively valuing these services is not just beneficial, but absolutely crucial for developing sustainable urban planning strategies that genuinely support and elevate the lives of city dwellers. In a related vein, green infrastructure stands out as an effective nature-based solution to combat the urban heat island effect. Research indicates that integrating features like green roofs, permeable surfaces, and urban forests can significantly cool down cities, making them more comfortable and inherently more resilient to the escalating impacts of climate change [3].

This calls for a widespread adoption of integrated green solutions as a standard practice in urban design and development. The rapid expansion of urban areas has also brought about increasing human-wildlife conflict, where encounters between people and wildlife are becoming more frequent and complex [4].

These interactions span a wide spectrum, from minor inconveniences to significant challenges for both human communities and animal populations. Addressing this issue requires a deeper understanding of the underlying drivers of such conflicts and the development of effective management strategies to foster coexistence in our increasingly urbanized landscapes. Concurrently, urban environments face significant challenges from pollution, particularly urban soil contamination. City soils are frequently found to be laden with heavy metals, various organic pollutants, and microplastics [5].

This pervasive contamination poses direct and indirect risks to human health, especially affecting vulnerable populations, underscoring an urgent need for robust soil management and remediation efforts across urban environments to protect public health. Amidst these challenges, urban agriculture emerges as a powerful tool for promoting food security and sustainability. Reviews demonstrate that cultivating food within city boundaries can significantly enhance local food supplies, drastically reduce food miles, and contribute to the creation of greener, more resilient communities [6].

Beyond its direct contributions to food production, urban agriculture also provides substantial social and economic benefits, pointing towards the potential for more localized, environmentally friendly, and equitable food systems. Furthermore, the establishment of urban ecological networks is vital for biodiversity conservation. Connecting disparate green spaces and natural habitats within cities is essential for facilitating species movement, genetic exchange, and the overall health and functionality of urban ecosystems [7].

Effective planning and deliberate implementation of these networks are key strategies to counteract habitat fragmentation and ensure the sustained vitality of urban wildlife populations. Cities themselves function as complex social-ecological systems where human and natural components are profoundly intertwined. Successful adaptation to climate change in these systems relies heavily on understanding these intricate interactions, integrating diverse community involvement, and systematically building adaptive capacity across both the social and ecological dimensions to significantly boost urban resilience [8].

Moreover, the sensory environment, particularly urban soundscapes, plays a crucial role in human well-being. Research highlights that the sounds experienced in cities markedly affect health and quality of life [9].

Positive soundscapes, rich with natural sounds, contribute positively to well-being, while the ubiquitous presence of excessive noise pollution can unfortunately lead to stress and various other negative health outcomes. This underscores the importance of thoughtful urban planning that gives as much consideration to acoustic environments as it does to visual aesthetics and infrastructure. Finally, the concept of biophilic urban design offers compelling benefits for human health and well-being [10].

This design philosophy advocates for the deliberate integration of natural elements and processes into urban spaces. This means incorporating features such as abundant natural light, engaging water features, and expansive views of greenery, all of which have been shown to effectively reduce stress levels, improve cognitive function, and cultivate stronger community connections. Ultimately, biophilic design presents a powerful and compelling case for consciously designing cities to deeply connect people with nature, thereby creating healthier, more engaging, and ultimately more livable urban environments for everyone.

Description

The multifaceted nature of urban environments necessitates a comprehensive understanding of their ecological dynamics and their profound impact on human well-being. A global review underscores that urban green infrastructure is not merely aesthetic; it is fundamentally critical for maintaining biodiversity. Carefully planned green spacesâ??including parks, green roofs, and strategically placed street treesâ??play a vital role in supporting diverse species within city limits. The core message is that strategic design and robust connectivity of these green elements are essential for fostering ecological resilience, moving beyond isolated green patches to create a truly interconnected and supportive urban ecosystem [1]. This approach ensures that urban areas can actively contribute to global biodiversity conservation efforts.

Further exploring the intrinsic value of urban natural systems, it becomes clear that urban ecosystem services are profoundly linked to human well-being [2]. Natural functions in cities, such as providing clean air and water, regulating local climate, and offering essential recreational spaces, deliver significant benefits that directly enhance residents' quality of life. Valuing and integrating these services into urban planning is crucial for building genuinely sustainable cities that support their populations. For instance, green infrastructure acts as a powerful nature-based solution for mitigating the urban heat island effect. Implementing features like green roofs, permeable surfaces, and urban forests can significantly cool down cities, making them more comfortable and remarkably resilient to the increasing impacts of climate change [3]. This represents a compelling call for integrated green solutions to become a cornerstone of urban design principles.

However, urban expansion also brings significant challenges, notably the rise of human-wildlife conflict [4]. As cities grow, encounters between people and wildlife become more frequent, ranging from minor nuisances to considerable threats for both humans and animals. Understanding the drivers of these conflicts and developing effective management strategies are paramount for fostering coexistence in increasingly urbanized landscapes. Another pressing issue is urban soil pollution. City soils are frequently contaminated with a cocktail of heavy metals, various organic pollutants, and microplastics [5]. These contaminants pose direct and indirect risks to human health, disproportionately affecting vulnerable populations. This highlights an urgent need for advanced soil management and remediation strategies to safeguard public health and environmental integrity in urban settings.

In contrast to these challenges, innovative urban practices offer pathways to sustainability. Urban agriculture, for instance, holds substantial potential for enhancing food security and fostering overall sustainability [6]. Cultivating food within city limits not only boosts local food supplies and reduces 'food miles' but also creates greener, more resilient communities. Beyond its direct food production benefits, urban agriculture delivers social and economic advantages, promoting a more localized and environmentally friendly food system. Complementing this, urban ecological networks are indispensable for biodiversity conservation. Establishing connected green spaces and natural habitats within cities is vital for species movement, genetic exchange, and maintaining overall ecosystem health [7]. Effective planning and implementation of these networks are critical for countering habitat fragmentation and ensuring the vitality of urban wildlife populations.

The intricate relationship between urban social and ecological systems is central to climate change adaptation. Cities are complex entities where human and natural elements are deeply intertwined. Successful climate adaptation strategies depend on a thorough understanding of these interactions, coupled with integrating community involvement and building adaptive capacity across both social and ecological components to significantly boost urban resilience [8]. Furthermore, the acoustic dimension of urban life, or urban soundscapes, profoundly affects human well-being. The sounds people experience in cities significantly influence their health and overall quality of life [9]. Positive soundscapes, rich in natural sounds, contribute to well-being, while ubiquitous and excessive noise pollution can lead to stress and other negative health outcomes. This underscores the necessity for thoughtful urban planning to prioritize acoustic environments alongside visual and structural design.

Finally, biophilic urban design emerges as a powerful paradigm for enhancing human health and well-being [10]. This approach advocates for the deliberate integration of natural elements and processes into urban spaces. Incorporating features such as abundant natural light, engaging water features, and expansive views of greenery has been consistently shown to reduce stress levels, improve cognitive function, and cultivate stronger community connections. This compelling evidence makes a strong case for designing cities that deeply connect people with nature, ultimately fostering healthier, more engaged, and more resilient urban populations. The synthesis of these diverse aspects paints a comprehensive picture of the challenges and opportunities in creating truly sustainable and human-centered urban environments.

Conclusion

This collection of reviews highlights the multifaceted challenges and opportunities in creating sustainable and healthy urban environments. A central theme is the critical role of urban green infrastructure, not only for fostering biodiversity and ecological resilience through strategic design and connectivity but also as a nature-based solution to mitigate urban heat islands and enhance climate change adaptation. These green elements, from parks to green roofs, also contribute significantly to urban ecosystem services, which are fundamentally linked to human well-being by providing clean air, water, and recreational spaces. However, urban expansion also brings issues like increased human-wildlife conflict and widespread urban soil pollution, with contaminants posing direct risks to human health. Conversely, innovative practices like urban agriculture show great promise for improving food security and sustainability, creating localized food systems, and delivering social and economic benefits. The importance of urban ecological networks for biodiversity conservation is also emphasized, countering habitat fragmentation by connecting natural habitats. Furthermore, the human experience in cities is shaped by factors like soundscapes, where positive natural sounds contribute to well-being, while noise pollution detracts from it. Ultimately, biophilic urban design offers a powerful framework for integrating nature into city spaces to reduce stress, improve cognitive function, and strengthen community bonds, making a compelling case for designing cities that deeply connect people with the natural world for overall health and resilience.
