This study examined the spatial-temporal transformations of peri-urban agriculture in the Metropolitan Area of Barcelona from 2003 to 2015, combining spatial analysis of land use changes with qualitative insights from stakeholder interviews and workshops. Results reveal that the significant decline of peri-urban agriculture is driven by a complex interplay of real-estate speculation, land fragmentation, infrastructure development, evolving land use policies, and ecological pressures from land abandonment and environmental protection. Despite efforts to preserve agricultural spaces, the decline of peri-urban farming remains significant.

This study investigated plastic debris as a reservoir for multidrug-resistant (MDR) enteric bacterial pathogens at two peri-urban agricultural sites in Dar es Salaam, Tanzania. Analysis of 140 environmental samples (soil, water, vegetation, plastic debris) showed higher concentrations of culturable pathogens on plastic debris, with presumptive E. coli loads of ~1 × 10^3 CFU per piece. Plastic debris harbored a greater proportion of MDR strains, including E. coli and K. pneumoniae resistant to critically important antimicrobials, indicating that plastic waste facilitates the survival of MDR pathogens and poses health risks.

This study evaluated the application of 150 t ha-1 of ramial chipped wood (RCW) to degraded peri-urban agricultural soils, comparing its effects on yield, soil health, and greenhouse gas emissions for spinach and sweet potato. Spinach grown with RCW showed the lowest productivity (1.16 – 0.32 kg m-2) among treatments, while sweet potato achieved the highest yield (1.72 – 1.99 kg m-2). High RCW doses initially led to higher CO2 emissions but significantly reduced N2O emissions for spinach (from 0.36 kg ha-1 to 0.07 kg ha-1) and enhanced soil organic carbon and nitrogen stocks for sweet potato, indicating agronomic and environmental trade-offs.

An NFT hydroponic system with 120 planting holes was successfully integrated with a 150 Wp solar panel to power the nutrient circulation pump. The system operated well for vegetable cultivation, demonstrating the potential of integrating hydroponic technology and solar energy for efficient and environmentally friendly agricultural practices at the village level.

Abie Assres Fenta, Habtie Anmaw · Discover Sustainability · Ethiopia (Debre Markos)

This qualitative study explored the adaptive livelihood strategies of evicted peri-urban farmers around the metropolis of Debre Markos, Ethiopia. Findings confirmed that farmers tend to hand over their land with insufficient compensation and are compelled to adapt to new livelihoods after losing farmlands. Many displaced young farmers experienced bankruptcy in new businesses due to a lack of business skills, and aged displaced farmers faced challenges adapting to new ways of life. The government did not provide adequate attention to training evicted farmers in technical, financial, and business planning.

An experiment conducted at IFCE - Campus – Iguatu - CE, Brazil, from April to May 2019, investigated the decomposition rate of mata-pasto (Senna uniflora) as green manure for chives (Allium fistulosum L.). Five treatments with different incorporation periods were tested. The results showed that incorporating mata-pasto 21 days before planting yielded the greatest plant height (33.7 cm), number of leaves (22.2), and aerial dry mass (1.54 g plant⁻¹), not statistically differing from 28 days before planting.

Gitanjali Nanda · International Journal for Research in Applied Science and Engineering Technology · India (Bhubaneswar)

This study examined the spatial, institutional, and planning feasibility of integrating urban agriculture into the urban planning structure of Bhubaneswar, India. Using a mixed-method planning framework, it evaluated urban land availability, rooftop feasibility, food accessibility, supply-chain dependency, institutional readiness, and decentralized food-production potential. Findings indicated that urban agriculture integration within statutory planning systems remains limited in rapidly urbanizing Indian cities, and vendor assessments showed strong dependence on peri-urban and external food inflows contributing to seasonal price instability and food wastage.

This qualitative study explored the technical, institutional, and commercial aspects of urban agriculture (UA) in two Ethiopian secondary towns, Dessie and Kombolcha, through 68 key informant interviews and 11 focus group discussions. It found that nearly 90% of local leafy vegetables are sourced via UA, but insecure land rights, limited policy support, and informal trading systems hinder its impact. Informal markets also cause post-harvest losses, disproportionately affecting women.

Gang Wang · Agricultural History · China (Shanghai)

This historical analysis of Shanghai's vegetable supply system examines the limitations of peri-urban agriculture. In the early 1950s, Shanghai relied on distant rural areas for vegetables, shifting to suburban production in 1958 after rural sources were cut off. Efforts to sustain this suburban-centric system faced challenges, and government attempts to phase out the planned economy in the 1980s had limited effect. By the early 1990s, the suburban-centric system was abandoned, leading to a return to nonlocal vegetable predominance.

A study of the "Ceinture verte" (Green Belt) in Ouagadougou, Burkina Faso, as a nature-based response to climate adaptation. Established in 1976 and relaunched in 2018, the initiative combines forestry development with urban agriculture, aiming to contain urban sprawl, improve the local climate and strengthen the capital's resilience. The study combined a diachronic analysis of Landsat imagery from 1984-2024 with interviews of institutional actors, associative partners and direct beneficiaries. Results show significant contributions — expansion of dense vegetation in some areas, a perceived improvement in air quality, the creation of income-generating market-gardening activities, and the inclusion of vulnerable populations — but also reveal strong constraints: illegal occupations covering a significant share of the land, fragmented governance, limited access to water, security fragility, and still-limited involvement of local residents. The study discusses the feasibility of a trajectory to 2050 between an optimistic scenario conditional on structural reforms and a critical scenario underscoring current limits, and offers lessons transferable to urban adaptation policies in other Sahelian metropolises.

A quantitative study of Karangmukti Village, Bungursari District, Purwakarta Regency, Indonesia, analyzing the influence of livelihood capital on the livelihood resilience of farming households. The village has been undergoing agricultural land conversion: the agricultural land area was about 206 hectares before the change, roughly 30 hectares were converted in 2025 (mainly for industrial and residential development), leaving about 176 hectares, and further conversion is planned for 2026-2027, which may further reduce the amount of productive agricultural land. Samples of farming households were drawn using the Slovin formula and cluster sampling, with data collected via questionnaires, interviews, observation and documentation, and analyzed using quantitative descriptive analysis and Smart-PLS. The results show that livelihood capital among farming households was at a moderate level, with natural capital as the most dominant component, and livelihood resilience was also categorized as moderate; livelihood capital was found to have a statistically significant positive influence on livelihood resilience.

For Burkina Faso, a circular Water, Energy, and Food (WEF) nexus framework was developed that couples wastewater reuse in peri-urban agriculture with biomass energy recovery from crop residues, using Material Flow Analysis, a screening-level Life Cycle Assessment, four-scenario simulation (baseline, water reuse only, biomass only, full circular integration) calibrated for 2005-2024, an exploratory STIRPAT elasticity analysis, and Monte Carlo uncertainty propagation around a composite Nexus Efficiency Index. Every quantitative result is a simulated output from a literature-constrained synthetic dataset rather than an empirical measurement for Burkina Faso; under the central assumptions, the fully integrated circular scenario was modelled to reduce freshwater abstraction by about 25-40%, increase yields by 20-40%, and cut farm-gate CO2-equivalent emissions by 30-45% relative to the linear baseline. The mobilizable biomass potential of cotton stalks and rice husks was estimated at around 44,891 tonnes of oil equivalent per year, with indicative payback periods of 5-10 years for small biogas digesters and gasifiers in representative peri-urban configurations.

A study introduces and validates a novel Deep Water Culture hydroponic roof system as a building-integrated solution for enhancing indoor thermal conditions and energy efficiency in Mediterranean climates. Unlike conventional green roofs, the system removes the soil layer and uses a water-based nutrient solution that simultaneously supports plant growth and acts as a thermal energy buffer; a full-scale prototype was experimentally tested on an existing office building in Catania, Italy, and transient thermal modelling with TRNSYS then simulated different roof configurations using the experimental data. Results show the hydroponic roof reduces indoor peak temperatures by up to 2.8°C in summer, increases them by 2.4°C in winter, and shifts heat flux peaks by up to 16 hours, with annual simulations indicating energy savings of 47% for space cooling and 51% for space heating.
