Intensive farming in urban suburbs often causes habitat loss, soil erosion, wastewater discharge, and agricultural productivity decline, threatening long-term benefits for the local community. We developed a nature-based solution for sustainable land restoration by establishing “Green Treasure Island” (GTI). The aim of this study is to evaluate the ecological restoration effectiveness of GTI and explore its feasibility and replicability for future applications. The core eco-functional zone of GTI—a 7 hm² forested wetland—embedded a closed-loop framework that integrates land consolidation, ecological restoration, and sustainable land utilization. The forested wetland efficiently removed 65% and 74% of dissolved inorganic nitrogen and phosphorus from agricultural runoff, raised flood control capacity by 22%, and attracted 48 bird species. Additionally, this biophilic recreational space attracted over 3400 visitors in 2022, created green jobs, and promoted local green agricultural product sales. Through adaptive management and nature education activities, GTI evolved into a landmark that represents local natural–social characteristics and serves as a publicly accessible natural park for both rural and urban residents. This study demonstrates the feasibility of creating GTI for improving ecosystem services, providing a practical, low-cost template that governments and local managers can replicate in metropolitan rural areas worldwide to meet both ecological and development goals.

Background: Community gardens are increasingly popular in Canadian cities, serving as transformative spaces where immigrants can develop self-reliant strategies for accessing culturally familiar and healthy nutritious foods. However, numerous facilitators and barriers exist that limit the engagement of racialized groups such as Black-identifying immigrants. Using a socio-ecological framework, this research explores barriers and facilitators of engagement of Black African immigrants in collective community gardening in Alberta, Canada. Methods: The study adopted a community-based participatory research (CBPR) approach using mixed methods. Data collection included structured surveys (n = 119) to assess general engagement, facilitators, and barriers; in-depth interviews (n = 10) to explore lived experiences; and Afrocentric sharing circles (n = 2) to probe collective perspectives in relation to engagement in collective gardening. Participants were purposefully recruited through community networks within African immigrant-serving community organizations. Results: Our findings revealed how barriers at various levels of the socio-ecological model (SEM) interact to shape the interest and engagement of African immigrants in collective community gardening. Access to collective gardens was associated with significant benefits, including maintaining healthy foodways, knowledge exchange, growing social capital, and community connections that support overall wellbeing. Conclusions: This study contributes an accessible framework for understanding and addressing the complex barriers that limit engagement in community gardens for vulnerable communities, while highlighting opportunities for creating more inclusive and culturally responsive urban agriculture initiatives.

This review explores innovative advancements in agriculture and food technology, from urban farming (e.g., vertical farming, aquaponics, and hydroponics) to regenerative agriculture and agroforestry practices that enhance soil health and biodiversity. We also examine food production in extreme environments, including desert agriculture and space agriculture, as well as advances in biotechnology, synthetic biology, and nanotechnology, that enable improved crop yields and nutrition. The transformative role of AI in precision farming, predictive analytics, and water management is highlighted, as well as the importance of bioproducts and eco-friendly innovations. Finally, we discuss the vital role of policy, regulation, and community-driven approaches in shaping a resilient global food system. Through the integration of technology with sustainable practices, this review aims to inspire research into solutions that ensure future food security while preserving our planet. Full article

As global food demand rises, urban agriculture models, such as vertical and terrace farming, have gained traction, especially amid crises like the Ukraine war and COVID-19 pandemic. Climate change remains the most significant threat to global food security. According to the latest FAO analysis, which encompasses assessments from 1990 to 2023, approximately 40% of economic losses resulting from climate-related hazards, including droughts and floods, have impacted the agriculture sector. This has reduced yields, increased production costs, and worsened food insecurity, affecting millions. Urban gardens offer a solution, enhancing food resilience. A systematic PRISMA-based review analyzed studies from Scopus and reports from organizations like the FAO. Over 3329 documents were reviewed. Publications on food resilience grew by 50% in four years, with the US leading with 700 projects. Agricultural and biological sciences dominate research (45%). Urban gardens focus on educating communities about food security and improving food systems. Mobile gardens with portable labs maximize urban spaces, turning rooftops and terraces into productive areas. These initiatives empower communities to grow food, promote nutrition education, and foster social connections. Urban gardens, though not fully sustainable, as they can consume up to 35% more energy per kg of food than optimized traditional farms and generate a 20–40% higher carbon footprint if using imported substrates or plastics, are key for resilient food systems, yielding up to 20 kg/m²/year, reducing transport emissions by 68% (vs. 2400 km supply chains), and using 90% less water than conventional agriculture.

Conflicts between humans and Japanese macaques (Macaca fuscata) have intensified due to urban and agricultural expansion, reducing natural habitats and pushing macaques into human settlements. This review examines strategies for managing human–macaque coexistence in Japan. Since the 1970s, urbanisation and deforestation have led to increased macaque migration into populated areas, resulting in property damage, crop loss, and, in some cases, aggressive encounters. The growing macaque population underscores the urgency of effective management programmes. Strategies include preventive measures, such as weeding to limit food sources, habitat modification, and community-based interventions to reduce attractants. Non-lethal deterrents, including visual and auditory scare tactics, trained guard animals, and electric fences, have been implemented to discourage macaques from entering human spaces. Physical barriers, such as fences and buffer zones, provide long-term mitigation but require maintenance and community cooperation. Fertility control, including sterilisation and hormonal contraception, offers a long-term population management solution but presents logistical challenges. Lethal control and capture-relocation, though controversial, remain options for particularly problematic individuals. Additionally, integrating One Health and One Conservation approaches into macaque management allows for a holistic strategy that considers disease risks, ecological balance, and ethical implications. A balanced management plan that incorporates multiple strategies, community participation, and continuous monitoring is crucial for mitigating conflicts and fostering sustainable coexistence between humans and macaques.

The number of studies on submarine groundwater discharge (SGD) and the evidence of its significance in biogeochemical cycling and potential impacts on the chemical and ecological status of coastal waters is increasing globally. Here, we briefly present SGD studies from the Baltic Sea identified along the coastlines of Denmark, Finland, Germany, Poland, Sweden and Russia in the southwestern, southern and north–northeastern parts of the Baltic Sea. We introduce a digital SGD map viewer and information platform enabling easy overview and access to information on identified SGD sites in the coastal areas of the Baltic Sea. SGDs potentially transport critical pollutants from urban and agricultural areas on land to the marine environment. The pollutants include nutrients, dissolved organic and inorganic carbon, metals, pharmaceuticals, and other emerging contaminants, potentially harming marine ecosystems and biodiversity and possibly contributing to the poor chemical or ecological status of coastal waters, affecting human and environmental health. We focus on case studies from Finland, Germany, Poland and Denmark that include the results and interpretations from the applied geochemical, geophysical and geological methods, as well as bionic autonomous underwater vehicles (AUVs) for locating, investigating, modelling and visualizing SGD sites in 2D and 3D. The potential Pan-European or even global SGD information platform established within the European Geological Data Infrastructure (EGDI) enables the easy combination and comparison of map layers such as seabed sediment types and coastal habitats. The EGDI map viewer provides easy access to information from SGD studies and may serve as an entry point to relevant information on SGDs, including contents of pollutants, for the scientific community and policy-makers. The information potentially includes the results of model simulations, data from near real-time sensors at permanently installed monitoring stations and surveys in time and space conducted by AUVs. The presented digital SGD information platform is particularly pertinent to the UN Sustainable Development Goal (SDG) No. 14, which focuses on the conservation and sustainable use of oceans and marine resources.

Data4HumanRights’ training materials have been developed as open-source and tailored to limited-resource settings, where community data collectors often live and work. Access to training on data collection, analysis, and visualisation to support the advocacy of vulnerable groups is essential, particularly in the context of increasing human rights challenges such as land rights, adequate housing, conflicts, and climate justice. This paper provides an overview of how the training materials were co-developed with community data collectors in Nigeria and Kenya, offering insights into the fundamental principles (i.e., inclusiveness, adaptive, limited resources, and being gender- and incentive-sensitive) and the structure of the open-access training materials. The development process resulted in 28 modules, each designed to be delivered in a face-to-face format in less than one day by a local trainer. To maximize adaptivity, the training modules can be mixed and matched (e.g., as individual modules or a learning path of several modules around a specific training need). The individual modules cover a range of methods and tools that are useful to human rights work and community advocacy, e.g., documenting evictions, performing rapid needs assessments after acute crises, community profiling, and monitoring community development indicators. The training materials contain instructions for the training facilitator(s) and all necessary training materials. To ensure inclusivity, the training covers both basic and advanced topics, with most modules designed to address basic needs that can be followed using a mobile phone, thereby avoiding the need for computers or printed handouts. The training results in Nigeria and Kenya showcase applications, including mapping waste problems and addressing forced evictions. Trained community groups produced maps of waste piles to prioritize community actions, such as finding space for urban agriculture, and conducted rapid needs assessments during a massive eviction. This approach helps reduce power imbalances and empowers community groups to effectively manage and utilise their own data. Full article

During the COVID-19 pandemic, the role of housing in controlling the spread of the virus was limited, as policies primarily focused on short-term measures such as lockdowns and social distancing. As the pandemic recedes, a shift has occurred towards restructuring the environment to confront future health crises better. This research thoroughly evaluates existing literature and housing complexes. It recommends that future projects prioritize several key features: ample exposure to natural environments, opportunities for growing food, encouragement of casual social interactions, inclusion of communal spaces, and provision of areas for exercise to help reduce the risks of contagion and alleviate the mental health impacts on residents. Based on research conducted during and after the pandemic, current recommendations for housing often provide generalized suggestions or propose ideal layouts through diagrams. This approach can be unrealistic from both spatial and economic perspectives and fails to inspire or stimulate creativity. This paper, by contrast, reviews and analyzes historical housing projects while critically examining three case studies that have the potential to inspire future designs. The goal is to provide officials, architects, and stakeholders with a series of practical possibilities and guidelines that contribute to the post-COVID home design process by making it more health-conscious and fostering the creation of new types of neighborhoods that can significantly impact the planning of cities in California.

Girsu, the modern site of Tello (southern Iraq), represents one of the earliest known urban centres of the ancient world, along with Uruk, Eridu, and Ur. During the 3rd millennium BCE (3000–2000 BCE), Girsu was revered as the sanctuary of the Sumerian heroic deity Ningirsu, who fought with supernatural beasts and made possible the introduction of irrigation and agriculture in Sumer. While much is known about the gods, their roles, and rituals inside the temples, there is little textual or archaeological evidence concerning the rituals that took place in the large open-air plazas adjacent to the temples. These areas within the sacred precinct were where the general population would gather to participate in festivals and ceremonies to honour the gods. To better understand the ancient cultic realm in southern Mesopotamia, an in-depth investigation of a favissa (ritual pit) discovered within the sacred precinct at Girsu was undertaken. The excavations recovered a large quantity of ceramics and animal remains that had been used for ritual purposes. Through the study of archaeological remains of cultic spaces at Girsu, information on ritual behaviour such as sacrificial animal slaughtering and consumption for the purpose of feasting, the types of libations provided to quench the thirst of the gods, and the distance travelled to take part in the annual festivals to pay homage to the patron god of their sacred city were explored. Analysis of the associated ceramics, cuneiform texts, and zooarchaeological remains (including stable isotope data), allowed a multi-faceted and integrative approach to better understand ceremonial behaviour and ritual feasting in this sacred city. New insights into communal and performative participation in ceremonies, especially by non-elite individuals, are generated. These data increase our knowledge not only of how Girsu’s citizens organised their sacred spaces and religious festivals, but also of how they behaved in order to satisfy the ever-demanding needs of their gods.

Logistics, distribution models, and landscapes of food production strongly influence the space of our cities and territories. In addition to the network of large-scale retail distribution that is diffused in urban and non-urban areas, with this contribution, we study the presence of new forms of the local and sustainable distribution of food (such as Alternative Food Networks, and community-supported agriculture). Studying and understanding how these distribution models can support and be integrated within a landscape planning and design approach is explored through the Analytic Hierarchy Process (AHP), a multi-criteria decision analysis method. Through the specific focus of a Food Hub localization, the aim is to demonstrate how distribution models can not only support but also integrate into landscape planning and design. The fundamental objectives for structuring and locating a Food Hub can be organized under three strategic objectives: pursuing the benefit of people, the planet, and profit. The choice of one distribution method over others, or what is the best location and condition for distribution centers, is the question we have tested with the collaboration of “L’Ortazzo” Association. The case study is a solidarity purchasing group located in the upper Valsugana valley area (Trentino Region, Italy), a supra-municipality reality involving about a hundred families that, currently, do not have a physical distribution center.

Urban parks serve as vital spaces for leisure, social interaction, and nature engagement. At the same time, climate change disproportionately impacts densely populated megacities. While extensive research exists on climate change’s effects on mortality, agriculture, and economic activities, less is known about its impact on urban park usage. Understanding their temporal usage and how temperature changes affect park visitation is crucial for maximizing park benefits and building resiliency. This study analyzes long-term, hourly park visitation data on Dallas, Texas, using digital trace data from SafeGraph (San Francisco, CA, USA), which covers mobile records from approximately 10% of U.S. devices. We focus on five established parks in Dallas and examine their historical temperature data from 2018 to 2022. Descriptive statistics and scatter graphs are utilized to analyze temperature- and demographic-specific visitation patterns. The results of the study highlight the impact of climate change on park visitation and reveal how extreme temperatures influence visitation patterns across parks in Dallas. Additionally, this study explores the differences in visitation based on weekdays versus weekends and highlights demographic disparities. Notably, we examine the implications of nighttime park usage during extreme heat conditions. Our work is informative for urban planners seeking to improve park facilities and comfort amid climate change, ultimately enhancing the resilience and well-being of urban communities. Full article

In the context of waterfront-space design, this study examines the impact of plant enclosures and the ratio of water bodies to green spaces on the microclimate, aiming to enhance the climate environment and mitigate urban heat. Utilizing Fujian Agriculture and Forestry University as a case study, the research selects the summer solstice as a representative weather condition, conducts field measurements and model validation for four types of waterfront vegetation, and creates 80 scenarios with varying plant enclosures and water to green space ratios using ENVI-met 5.0.2software. This comprehensive analysis seeks to identify the optimal water–green space ratio for waterfront areas. Key findings include: (1) The efficacy and applicability of ENVI-met software for microclimate studies are confirmed. (2) Waterfront plants have cooling and humidifying effects on the microclimate environment. The order of cooling and humidifying effects of different plant community structures was as follows: tree–shrub–grass > tree–grass > shrub–grass > grass. (3) The cooling, humidification, ventilation, and human comfort levels are influenced by the specific enclosure conditions and water to green space ratios; a ratio of 1.8:1 is the most effective for cooling and improving human comfort, while ratios of 4:1 and 1:4 are better for humidification and ventilation. These results offer valuable insights for designing waterfront spaces in hot and humid climates. Full article

Allotment gardening as element of green infrastructure and integral part of urban agriculture supports the city’s sustainable development and builds urban resilience. The COVID-19 pandemic provided an opportunity to revisit allotment gardening in a situation of unprecedented health crisis. Therefore, this study aims to recognise the importance of allotment gardens during the COVID-19 pandemic in Poznań (Poland), a city with a ‘famine of plots’ observed for years. A survey was conducted among allotment holders who had acquired plots during the course of the pandemic and in-depth interviews were conducted with the president of the Polish Allotment Federation of Poznań and the managers of the allotment gardens wherein we had identified the highest proportion of new allotment holders. Information was collected during field research, also using available statistical data. The methods used included desk research and a case study, interviews and a survey. The results of the study show that the pandemic caused a renaissance in allotment gardening. The increased interest in allotments triggered an increase in their price, thus further restricting access. A generational change in the allotment community was also noted, with young people appearing on allotments. However, the survey showed no change in the use of allotments: recreation is still their dominant function, with allotment holders focusing on cleaning and renovation work. For new allotment holders, the plot was a green refuge in times of isolation, a place for contact with nature, loved ones and family, and a safe space for relaxation. Our research indicates that allotment holders also appreciated its positive impact on their physical and mental health.. Moreover, the study indicates that despite the long-standing shortage of allotments in the city, only restorative allotment gardens are being created. Full article

Does our food for thought come virtually from the internet? When we take a long view, the instant stroke of a keyboard pales in comparison to the centuries-old evolution of real food harvesting and the generation and exchange of ideas, which have resulted in creative capital. The vernacular architecture of the agricultural built environment has almost dematerialized in its transition from the ancient pre-industrial era to the post-truth world, to become almost only an imagined concept. The symbology of the common threshing terrace of a Portuguese remote mountain village can now be found in multiple spaces of the urban realm, including in the metaphor of a community arts incubator’s modus operandi in Albany, New York (USA). How has the concept of food for thought developed and materialized? How has it evolved? And what are some of the expected ways it might be utilized in the future? The purpose of the paper is to trace the evolution of this concept and its elements via the BLC Framework. The methodology employs a time analysis of approximately three centuries to distinguish three distinct evolutionary phases: (i) the pre-industrial era, (ii) the industrial era, and (iii) the information-driven era. The key finding is an up-to-date discussion of the food for thought concept in two distinct geographical worlds and three-time eras, as well as a set of lessons learned according to a protest poem and a rock song. The results are presented in the form of five lessons learned with implications for public policy: the first two lessons pertain to issues of procedural justice as encapsulated in the anonymous ‘The Goose’ poem, while the last three result from a discussion of selected verses in Nick Cave’s ‘Fable of the Brown Ape’ rock song.
