In Karangmulyo Village, Indonesia, the COVID-19 pandemic led to a decline in the quality and productivity of community gardens and parks. A village nursery revitalization program aimed to overcome these negative impacts, restore land function, and boost the morale of women farmer communities through infrastructure improvements, adaptive crop planting, sustainable agricultural techniques, and community involvement. However, this abstract does not report on the specific effects of this program, such as the improvement of overall community welfare or the ensured sustainability of the village environment.

This study provides a framework for selecting and operationalizing indicators for a comparative sustainability assessment of different urban agriculture types, exemplified by Community Supported Agriculture (CSA) and vertical farming. Based on a qualitative content analysis of vision guidelines, results suggest that CSA can be considered the more sustainable form across all three sustainability dimensions. However, considering vertical farming's main benefit is increased food production efficiency, it is suggested to balance its shortcomings and lack of vision on social justice, biodiversity conservation, and food quality by fostering a hybrid model of community supported vertical farming. This suggestion implies that vertical farming alone has limited effects in these aspects.

This study investigated the connection between local farmers markets (FMs), community-supported agriculture (CSAs), and physical well-being at the state level across the 50 states of the United States. Analyzing 2016 data from the United States Department of Agriculture using an ordinal logistic regression model, the study found an inconclusive relationship at the state level. While local FMs and CSAs may increase physical well-being, this study did not find such an increase.

This study investigated resilience and vulnerabilities in fresh produce donation partnership programs to food pantries in Iowa during the COVID-19 pandemic. Findings revealed a significant decrease in labor hours during the pandemic years of 2020–2021, attributed to government policies and social distancing requirements. Volunteer shortages, donation inconsistency, and exclusionary community practices appeared to be inherent vulnerabilities of volunteer-based food donation programs.

This study investigated how urbanization relates to pollination by growing 240 plants (squash and tomato) across six sites with varying urbanization levels in Chicago, Illinois. For tomatoes, the magnitude of pollen limitation increased with greater impervious surface, indicating more pronounced pollination deficits at highly urbanized sites. For squash, evidence of pollen limitation was found only at the most urban site, with a weak trend of pollen limitation of fruit set (but not seed set) increasing with impervious surface.

This 2024 essay in the Bulletin of the Atomic Scientists states that urban agriculture brings many benefits to its participants but is not guaranteed to be more climate-friendly than conventional agriculture. It adds that there are some specific steps urban farmers can take to cut carbon emissions.

Setyardi Pratika Mulya, Delik Hudalah · Regional Sustainability · Indonesia

This study assessed sustainability based on agricultural intensity in peri-urban villages of Karawang Regency, Indonesia, using a village agriculture index (VAI), a village sustainability index (VSI) adapted from a local sustainability index via factor analysis, and a logical matrix analysis for level of agricultural sustainability (LoAS). Peri-urban villages with high agricultural intensity tended to show lower social welfare and economic development and higher disaster risk; high agricultural intensity did not necessarily ensure prosperity, and economic disparity existed among villages, leading the study to conclude that encouraging diversity in agricultural intensity is more important than promoting agricultural intensity itself.

This paper addresses the limited understanding of conditions under which stress-tolerant "nurse" plants can facilitate stress-intolerant "protégé" species on extensive green roofs for urban agriculture. It proposes a framework and linear model, integrating trait–environment theory and facilitation ecology, to make testable predictions on protégé species performance along stress gradients. The framework aims to help researchers assess the feasibility of nurse–protégé interactions under various environmental conditions.

This study investigated the implications of urban growth on maize yield in Harare metropolitan city, Zimbabwe, from 1984 to 2018 using Landsat data. Cropland area was reduced from 11,120 ha in 1984 to 2631 ha in 2018. Consequently, the estimated average maize yield decreased significantly from 52,264 tons in 1984 to 12,366 tons in 2018, demonstrating that urban growth has the potential to compromise food security.

This phenomenological study investigated the views and experiences of 9 headteachers and 9 teachers from 6 preschool institutions in Turkey and England regarding outdoor learning. It found that in Turkey, school gardens, equipment, and time spent outside are insufficient compared to England. While family participation in outdoor learning is more common in Turkey, teachers and headteachers there experience greater family pressure concerning child safety, illness, and dirty clothes, and feel anxious due to a lack of classroom assistance. Both countries showed insufficient inclusion of outdoor learning in vocational and in-service training.

A study in Bandung, Indonesia, surveyed 321 households to assess urban agriculture's contribution to household food fulfillment and income. The findings showed an insignificant 9% contribution to food fulfillment and a 41.5% contribution to income. This limited impact was attributed to metropolitan complexities, including restricted land access and increasing commercialization.

This study assessed information from multiple sources to design diversified cropping systems with vegetables and spice crops for cold temperate climates, integrating trait and observational data from databases, farmer surveys, and literature reviews. While farmers achieved medium to good levels of their main goals, they failed to reach desired multifunctionality with their polycultures. None of the individual data sources provided a comprehensive dataset, but combining them increased crop combination options while also increasing planning and management complexity.

A cluster randomized controlled trial in rural Nepal (n=680 school children aged 9-13 across 30 schools) investigated whether an integrated school and home garden intervention improved hemoglobin levels and reduced anemia. The intervention did not lead to a direct significant reduction in anemia, as nutritional improvements were not strong enough to impact hemoglobin levels. However, the program indirectly improved hemoglobin levels for children under 12 by increasing good food and hygiene practices at home, particularly for girls, young children, and those with literate caregivers.

The feasibility of using urine and greywater streams as nutrient solutions in a theoretical model of Building-Integrated Agriculture in Amsterdam was evaluated. Results showed it is feasible to use urine and greywater as nutrient solutions; however, treated urine had higher macronutrient concentrations than literature fertilizer recipes, requiring dilution with increasing amounts of greywater to match N or P concentrations. Consequently, P deficiencies in plants or excessive N concentration were found in the final wastewater-based nutrient solution.
