A bibliographic review of research on water quality in the Puyo River and its tributaries in Pastaza, Ecuador, compiled studies from scientific databases and institutional repositories reporting physicochemical, microbiological, and heavy metal parameters. The main sources of contamination were found to be wastewater discharges, fecal coliforms, and accumulation of heavy metals such as lead and mercury linked to urban, agricultural, and mining activities, with community perception aligning with technical findings as most of the population rated the water poor quality and associated it with health problems. Over the past twenty years, a progressive deterioration in water quality parameters has been documented, with increases in turbidity and pathogenic microorganisms despite some isolated recovery efforts, and the review concludes that lack of attention from the municipality and prefecture, together with the absence of continuous monitoring, is worsening the water crisis and demands comprehensive, participatory governance.

This qualitative study used thematic analysis of in-depth interviews with 10 residents of low-income neighborhoods in Selangor, Malaysia, to examine food access and the sustainability of food security. Five themes emerged: economic constraints, geographical and infrastructure barriers, food price and market fluctuation, limited involvement in urban agriculture, and coping strategies for food insecurity. Financial difficulty was found to be the most significant barrier to food access, forcing households toward less healthy but more affordable food, and while households' coping strategies were resourceful, they were unsustainable, underscoring the need for long-term policy intervention.

Using the author's own course, "Race, Gender, and Environmental Justice," as a case study, this article argues that justice-oriented climate education is strengthened when rooted in Black ecofeminist pedagogy. Set against the context of Jesuit educational institutions' commitments to sustainability since Pope Francis's 2015 encyclical Laudato Si', it examines how Black ecofeminist pedagogy contributes to interrogating epistemological authority, developing structural analytical frameworks and embodied engagement with the lived world, arguing that it challenges Western Christian epistemological, methodological and political norms and pushes Jesuit environmental education toward a more critical stance on racial and gender justice.

This study used a hermeneutic phenomenological approach supported by field observations to examine the lived experiences of long-term gardeners at the PPR Intan Baiduri public housing estate in Kuala Lumpur, Malaysia, exploring how grassroots gardening supports resilience, health and informal governance. It found that gardening provides retirees and low-income residents with routine, emotional wellbeing and opportunities for informal economic participation, that community gardens function as micro-level bioresource systems by repurposing reserve land, composting household waste and drawing on institutional collaborations with agencies such as DBKL and TNB, and that participants collectively organize planting cycles and maintain shared infrastructure while navigating labor constraints and fluctuating participation.

This review addresses a knowledge gap on how peri-urban residents in Asia and Africa adapt to the impacts of urbanization and climate change on water security. As rural-urban boundaries rapidly blur in the global South, peri-urban spaces are characterized by weakening access to water resources, depleting common property institutions and poor civic engagement, and the review presents the persistent marginalization of peri-urban residents from a water security perspective, while also showing that they do develop adaptation measures. Existing literature is found to focus primarily on (1) increased vulnerability of peri-urban agriculture and allied sectors, (2) barriers and enablers to water-security-related adaptation planning, and (3) justice in peri-urban areas, and the review calls for further study of emerging cooperation and collective action that could reduce conflicts between peri-urban and urban inhabitants and improve water security.

Focusing on Ghana, where floods driven by urbanization and climate change are destabilizing urban systems in which land tenure is integral, this study drew on political ecology and land-tenure-security frameworks to examine how floods affect the land tenure security of flood victims. Based on semi-structured interviews with flood victims and planning officials, it found that flood-induced rezoning and new planning schemes, tenant insecurity, relocation, loss of land documents, and threats to urban agriculture all affect flood victims' land tenure security; possessing land documents was found to be important for tenure security but not an absolute condition for victims' perceived security. Post-flood land-use planning for flood risk management was found to have dual potential — it can enhance tenure security and bolster community resilience, but when carried out in an exclusionary way that overlooks the urban poor, it can instead perpetuate inequality and tenure insecurity. The study recommends tenure-responsive land-use planning that embeds contextual, procedural, and distributive equity principles into planning responses to urban floods.

A book chapter on circular urban agriculture, discussing strategies for sustainable food production in rapidly growing cities. It surveys urban farming methods including rooftop gardens, vertical farming, hydroponics and community gardens, framing resource efficiency — using waste streams, conserving water, and minimizing inputs like soil and fertilizer — as the core of the circular approach, and describes water conservation and recycling (drip irrigation, greywater reuse, rainwater harvesting) and nutrient recycling through biosolids as key components for improving soil quality and productivity.

A qualitative study conducted semi-structured interviews with 35 stakeholders — home farmers, commercial producers, policymakers and agritech developers — in the United Arab Emirates, examined against the National Food Security Strategy 2051. It found 70% of home farmers engage in urban agriculture to reduce import dependency, but are constrained by high water costs (cited by 70%) and limited technical training (55%). Commercial farms widely use hydroponics (88%) and vertical farming (62%), though energy-water trade-offs limit scalability. Stakeholders emphasized AI-driven tools for water-use optimization (75%) and blockchain for traceability (45%); the most desired digital-platform features were real-time soil and weather data (90%), centralized subsidy access (80%) and market linkages (65%), though fragmented data systems currently limit their effectiveness. Policy implementation gaps persist, with 60% of farmers unaware of subsidy programs and minimal integration across agricultural initiatives; the study recommends expanding solar-powered irrigation subsidies, improving training and extension services, and developing a unified digital platform connecting farmers, policymakers and agritech stakeholders.

A study analyzed food security, dietary diversity and their socio-demographic determinants among households in Bamako, Mali, between 2018 and 2022. Using National Food Security and Nutrition Survey (ENSAN) data on 5,792 households, it applied descriptive statistics, bivariate analysis and multivariable logistic regression, with Household Dietary Diversity Scores (HDDS), Food Consumption Scores (FCS) and wealth quintiles as primary predictors. Household diets were cereal-based (99.3%) and largely lacking protein-rich foods such as eggs (20.1%) and legumes (36.7%). The prevalence of food security fell significantly, from 64.5% in 2018 to 59.2% in 2022 (p<0.01). Urban residence and higher education were strong positive predictors of food security (AOR 1.8, 95% CI 1.4-2.3, and AOR 2.1, CI 1.7-2.6, respectively), while households in the lowest wealth quintile (AOR 0.4, CI 0.3-0.6) and polygamous households (AOR 0.7, CI 0.5-0.9) showed significantly lower food security. The study concludes that Bamako's food insecurity stemmed from economic instability and educational disparities despite a degree of dietary diversity.

A systematic review following the PRISMA protocol, covering articles published between 2014 and 2024 in the CAPES and SciELO databases, analyzed the effect of school-based urban agriculture projects on students' emotional health. The review found that participation in school gardens was associated with a significant reduction in stress and anxiety levels and promoted the development of social skills. Pedagogical practices linked to urban agriculture were reported to foster a collaborative environment and improve emotional well-being, and the presence of green areas in schools was also found beneficial for academic performance and mental health.

A paper examines urban agriculture as a process capable of promoting environmental sustainability, social inclusion and the circular economy, proposing ways to use and develop it. Through an interdisciplinary approach based on "demand maps," it presents an implementation model aligning users' needs with design solutions. Critical analysis of case studies identifies benefits including reducing urban heat islands, supporting biodiversity, enhancing food security, fostering social cohesion, and aiding the development of vulnerable communities. The guidelines presented aim to encourage the use of demand maps in urban decision-making processes to support participatory, inclusive and sustainable strategies.

A study protocol describes FoodACT, a multimethod, quasi-experimental investigation of the existing Danish school garden program Gardens to Bellies (GtB) and its effects on children's food literacy (FL), climate change literacy (CCL), school motivation (SM) and physical activity (PA), preregistered on ClinicalTrials.gov (#NCT05839080). The study covers six GtB locations across Region Zealand and Region of Southern Denmark, recruiting approximately 1,600 fourth-grade GtB pupils as the intervention group and approximately 1,600 fourth-grade pupils from non-GtB schools as controls. Pupils grow, prepare and cook food across eight garden sessions; FL, CCL and SM are measured via pre- and post-intervention surveys, PA via accelerometry, and acute SM via text-message surveys, alongside semi-structured and focus-group interviews with garden facilitators and pupils on implementation and mechanisms.

A life cycle assessment (LCA) comparing the environmental performance of a conventional ceramic roof (CR) and a modular green roof (GR) planted with the edible species Pereskia aculeata. Primary data came from experimental GR prototypes monitored for one year, including irrigation volumes, plant development and rainwater retention across 50 rainfall events; secondary data were modeled from the ecoinvent database and literature. The analysis had three stages: comparing CR and GR construction and first-year use, sensitivity/uncertainty analysis of alternative GR materials, and a 30-year projection of use-phase impacts. In stage one, GR outperformed CR in 11 of 14 impact categories, with total normalized impacts 13% lower; 80% of CR's impact came from ceramic tile production, while in GR polymer components dominated, with polypropylene accounting for 82% of fossil depletion and polyester for 95% of ozone depletion. Substituting alternative polymers for the module and filter layers cut marine and freshwater ecotoxicity by over 70%. The optimized GR scenario had 71% lower normalized impacts than CR and outperformed it in 13 of 14 categories, with the 30-year projection confirming GR's continued advantage.

This essay surveys urban and peri-urban agriculture (UPA) as it has developed across Europe, North America, South America, Asia, and Africa. It argues that in South American, Asian, and African countries, UPA is oriented mainly toward meeting the food and income-generation needs of poor and economically excluded populations, who use food production to reduce their socioeconomic vulnerability, whereas UPA in European and North American countries serves different ends tied more to leisure, quality of life, and recreation in public spaces.

A 2025 study in the Journal of Sustainable Development Law and Policy used Onaiza, a low-rise mixed-use residential neighbourhood on Qatar's western coast representative of suburban Doha, as a case study to examine how urban agriculture could be integrated into land use policy as a climate-change mitigation strategy in Doha Municipality. Drawing on a literature review, examination of successful case studies, and expert interviews, it identified challenges and potential for permitting urban agriculture as a land use, then produced a design proposal amending land use policy through urban planning simulations, subsidies and other incentives. It starts from the premise that food systems, food security and urban agriculture are not yet well positioned within Qatar's existing land use policy, despite the country's vulnerability to food imports and to climate change.

A technical paper presenting a parallel agent-based framework for analyzing vegetable trade dynamics within a metropolitan area. It combines agent-based and discrete-event techniques to model interactions among farmers (who select crops based on market trends and environmental risk) and vendors and consumers (who adapt purchasing behavior to seasonality, prices and availability). To handle the computational demands of large-scale scenarios, it employs an optimistic approximate parallel execution strategy and a credit-based load-balancing mechanism to improve scalability. The framework is presented as enabling detailed analysis of urban food distribution systems relevant to smart cities and digital agriculture.

This study examined litter decomposition dynamics in food forests, perennial multi-layered food production systems gaining popularity as alternatives to intensive, input-dependent agriculture that rely on nutrient recycling via litter decomposition. Litter from Alnus glutinosa (black alder), Corylus avellana (common hazel), and Castanea sativa (sweet chestnut), ranging from high to low litter quality, was decomposed in food forests planted on former grasslands and compared with neighboring grasslands. Litter bags of varying mesh size were used to assess the relative contribution of microbes and micro-, meso-, and macrofauna to short-term litter mass loss, and abundance and biomass of key decomposer groups were quantified. Decomposer communities differed between land use types: food forests harbored a higher abundance of oribatid mites but a lower abundance and biomass of earthworms and lower arbuscular mycorrhizal fungi biomass than grasslands. Overall litter mass loss differed little between the systems, except that high-quality litter accessible to the full decomposer community lost more mass in grasslands. The lowest-quality litter (sweet chestnut) decomposed slowest, with its rate unaffected by mesh size or land use. High-quality leaf litter generally decomposed faster in grasslands than in food forests, and the distinct decomposer communities in young food forests did not favor breakdown of recalcitrant litter.

This chapter examines urban gardening in Christchurch, New Zealand, since the 2010 and 2011 Canterbury earthquakes through the lens of resilience — disaster resilience, community resilience, food resilience, and the broader notion of urban resilience. After discussing post-earthquake urban gardening projects in Christchurch, it shows that notions of food resilience are contextually interwoven with the region's earthquake disaster history. It finds, however, that recent initiatives show discussions of food resilience have broadened to become inclusive of a range of environmental, socio-economic, and cultural challenges, with Christchurch's urban gardens becoming part of a wider resilience narrative responding to more diverse crisis scenarios. The chapter argues that this broadening of discussion and focus creates new opportunities — including new funding avenues, research, and strategic investment — for urban gardening.

In rural primary schools of west-central Santa Fe province, Argentina, an anthropological study examined the relationship between education and environment. It reconstructs the social, productive and environmental context shaped by intensive agribusiness (agronegocio) and analyzes how this context affects school gardens, an activity rural teachers frame as part of Environmental Education. The analysis reveals tensions between the pedagogical mandate to develop school gardens, their reframing as Environmental Education, and the socio-environmental problems present in these settings, aiming to identify the limits and potentials of this pedagogical work around environmental issues.
