This report describes a community-service activity (PKM) conducted by Universitas Islam Jakarta with D'Shafa, a farming community in Jakarta focused on urban agriculture development, aimed at strengthening food security and economic welfare. The activity followed five method stages — education, training, technology application, evaluation, and program sustainability — with the goal of helping the D'Shafa Women Farmers Group (KWT) create value-added processed products. The activity produced value-added products through the use of a vacuum-frying machine for making fruit and vegetable chips, and it broadened KWT D'Shafa members' knowledge of preparing simple and digital financial reports and of digital marketing.

This concluding book chapter, drawing on interviews with community gardeners, reviews the themes of equality and substantiality in what community gardeners can tell us about nonreligion. It argues that community gardeners have a deep awareness of their entanglement with other terrestrial beings — humans, animals, insects, and plants — leading them into a distinct form of ethical engagement driven primarily by relationships and practices rather than by intellectual commitment to abstract norms (though these can sometimes be significant, citing Ezzy 2004). Nonreligion is characterized as being less about the absence of religion and more about substantive content — commitments, practices, and relationships — and the chapter argues that the concept of "lifestances" is the best way to conceptualize this substantive content, and that the religion/nonreligion binary must be transcended to understand humans as entangled in a network of terrestrial relationships.

This study examines morphometric traits — body weight and measurements of the head, chest, limbs, spine, and ears — of the Bambu Apus rabbit, a breed formed by crossing several rabbit breeds and adapted to the environment of DKI Jakarta, Indonesia, comparing 65 adult Bambu Apus rabbits against secondary data from 40 adult Rex and 40 adult New Zealand White rabbits. Analysis used SAS software v9.4: ANOVA (PROC GLM), Mahalanobis distance analysis (PROC DISCRIM), canonical discriminant analysis (PROC CANDISC), and phenogram construction (MEGA11). Discriminant analysis showed Bambu Apus rabbits differed morphometrically from Rex and New Zealand White rabbits: average body weight was 2473.54±480.13 g, higher than Rex (P<0.05); chest depth was 8.69±1.11 cm greater than both Rex and New Zealand White (P<0.05); and backbone length was 37.84±3.51 cm longer than Rex (P<0.05). Genetic distance and phenogram analysis showed low kinship between Bambu Apus and both Rex and New Zealand White rabbits, which the study suggests indicates potential for developing tropical-climate-adapted broiler rabbits.

Set against challenges to social equity, ecological balance, and global food availability from population growth and rapid urbanization, this review paper surveys existing literature linking urban agriculture to multiple Sustainable Development Goals — including poverty eradication, ending hunger, health and well-being, gender equality, economic growth and employment, inclusive urban development, sustainable consumption and production, climate action, land ecosystems, and global partnerships — and discusses policy implications for India. It compiles prior findings associating urban agriculture with locally grown food supply, resource optimization and emissions reduction through urban forestry, rooftop gardens and vertical farming, reduced food miles, and education, skill-building and community participation opportunities including for women and youth. The paper presents no original empirical data of its own.

A study of Beijing and Shanghai, China (2025) modeled decarbonization from adjusting the local-sourcing share of seven perishable food categories — vegetables, poultry, aquatic products, beef, and lamb among them — incorporating both production and cold-chain logistics emissions across multiple localization scenarios. Each 1% increase in localization of vegetables, poultry, and aquatic products cut 2020 emissions by 0.4-1.9 tCO2e, while the same 1% increase for beef and lamb raised emissions by 0.2-2.9 tCO2e; localization reduced the cold-chain emission share for every food category. A constrained "balancing strategy" cut 2020 emissions by about 0.76 MtCO2e (5%) in Beijing and 0.44 MtCO2e (2%) in Shanghai, and an unconstrained scenario maximizing urban agriculture use achieved 3-4 times more reduction. Under a business-as-usual projection, the strategy was estimated to offset over 90% of Beijing's added emissions by 2035, with a further 0.44 MtCO2e reduction possible in Shanghai. The findings indicate that importing more carbon-intensive ruminant meat while reallocating urban resources toward vegetables, poultry, and aquatic products could produce more sustainable food supplies in megacities.

A theoretical essay on hunger in Brazil (2025) applies the Public Policy Cycle Model to the persistent, structural problem of hunger in Brazilian politics, noting that hunger is not unique to Brazil — about two billion people worldwide experience moderate or severe food insecurity — while all Brazilian regions show nutritional deficits tied to inadequate or insufficient food intake. In this context, it frames urban and peri-urban agriculture (AUP) as a social and public-policy tool for promoting food and nutrition security, examining the agenda-setting and formulation stages of AUP policy through discussions from Brazil's National Conferences on Food and Nutrition Security. Noting the 2024 establishment of Brazil's National Urban and Peri-urban Agriculture Policy and its ties to the UN Sustainable Development Goals, the essay concludes that much remains to be done to strengthen AUP as public policy and consolidate its social, economic, and environmental impact, particularly to make it effective for promoting food and nutrition security.

Focusing on the Indigenous Muysca community of Suba in Bogotá, Colombia, this ethnographic study, framed within Participatory Action Research methodology, examines the unique and enduring forms of colonialism that Indigenous communities experience in urban environments. Having had their traditional territories abruptly urbanized, the Muysca experience urban coloniality through mechanisms such as displacement, environmental degradation and epistemicide, while engaging in embodied practices of contestation including language revitalization, urban gardening, and occupation of sacred sites that have become urbanized. The study explores dwelling as an embodied, place-rooted everyday experience to show how the Muysca produce alternative socioecological lifeworlds within the city, and argues that these embodied practices unsettle the logic of urban coloniality of nature that continues to drive Indigenous dispossession.

This study models spatial and temporal crop rotations on Amsterdam's rooftops using planting-structure optimization for crop rotation planning, to assess how much of the city's dietary demand for specific crop groups could be met by productive green roofs. Using average productive green roof crop yields and climatic variability from 2003-2021, it estimates Amsterdam's potential productive green roofs could achieve urban food self-sufficiency of 52% for selected crops (41-54% accounting for climatic and spatial variability), rising to 71% (50-71%) when the planting structure is optimized. Lettuce-broccoli occupies the largest productive green roof area, at roughly 100 hectares, and six vegetable types were found to match well with Amsterdam's dietary requirements.

Focusing on the Muak-dong neighborhood at the foot of Ingwansan mountain in downtown Seoul, South Korea, this piece examines human-plant relationships in a dense urban environment where edible plants inhabit various growing spaces alongside residents. Building on the recognition that growing food locally can be part of socio-environmental justice pathways through walkable urban environments, urban agriculture and food waste recycling, it argues that these spatial practices also constitute social infrastructure, providing places and means for interaction, exchange and sharing. While many cities have fragmented growing activities and scattered edible plants, the Muak-dong network and its diverse modes of food cultivation are described as extraordinary, forming a literal pathway — exemplified by a map for an urban vegetable walk — that binds together urban green space, edible plants, a fertiliser station and people. The contribution focuses on the visual presence of plants in this cityscape, specifically lettuce, to demonstrate the possibilities food cultivation affords in one of the most dense and contested environments.

A mixed-methods study assessed the viability of a low-cost hydroponic system using locally sourced Fermented Plant Juice (FPJ) as an organic input for lettuce production aimed at food security in the Zamboanga Peninsula, Philippines, examining acceptability, growth performance and economic feasibility. Estrosa and Olmetie lettuce varieties showed the best growth performance; nitrate was undetectable in Estrosa and Green Wave, while Olmetie and Invicta absorbed more nitrate with FPJ use, though all levels stayed within international safety limits and cadmium was not detected, while limited technical knowledge, material access and capital were identified as barriers to adoption.

This chapter finds that while collective urban gardening projects represent forms of resistance against market-based food systems, the precarization of urban natures, and real-estate dominance, their everyday practices often fail to deliver on these ideals and intentions, generating incomplete, contradictory, or temporary results. It proposes a heuristic frame linking space, time, and class to review prior urban-gardening research from a political-ecology perspective, tracing how space's materiality, time embedded in plant growth, and class differences conditioning gardeners' access to space and time produce these contradictions.

Two studies comparing consumers and non-consumers of Community Supported Agriculture (CSA) examined whether participation strengthens environmental, social and health consciousness and sustainable behavior. CSA consumers showed higher environmental and social consciousness than non-consumers, with social consciousness increasing over the course of participation, and reported more sustainable consumer behavior extending beyond food to other spheres of consumption.

This study used a System Dynamics model to simulate five 10-year policy scenarios for an informal settlement in a developing country, addressing settlement consolidation and women's access to formal employment: business-as-usual, time-quality, women's formal employment, circularity (including organic waste management with urban gardens and urban agriculture), and a comprehensive scenario combining all interventions. Individual solutions alone did not fully capture potential synergies, whereas the comprehensive scenario reduced by 47.5% the time needed to improve women's formal employability, a result linked to the settlement consolidation process.

Drawing on a three-year community gardening project co-created with newcomer (refugee) youth of color in North America, this qualitative study analyzed the youths' participatory, embodied and discursive work over the first two years of creating and caring for the community garden, examining how they re-establish relationships with land, air, water and more-than-human life in their newly adopted home. The analysis found the youths' participation centered an anti-racist praxis within the garden, and the study offers an expanded account of how race and climate are implicated together in migration.

A study of Palmira, Colombia — a city with a long tradition as the country's agricultural capital — finds that it nonetheless faces significant food insecurity. Prior research reviewed in the study attributes this to an aging rural population and young people's declining interest in farming (which has shrunk the available labor force and limited adoption of new technology), gender inequality that restricts women's access to agricultural resources and decisions, climate change impacts such as droughts and floods on production, and accelerated urbanization that has reduced cropland and fragmented the agricultural landscape. As a potential response, the study describes a pilot project at four sites in the city that installed small-space vegetable production systems, which it reports functioned as a viable source of fresh food in dense urban settings. The authors call for a multidisciplinary approach combining social, economic and environmental factors to address food insecurity in Palmira.

Focusing on the Parit Lalang area of Pangkalpinang City in Bangka Belitung, Indonesia, this qualitative case study used participant observation, in-depth interviews and documentation studies, analyzed thematically and via SWOT analysis. Urban agriculture there is carried out mostly in small home gardens and on vacant land, using hydroponic and traditional methods, with productive-age residents and housewives as the main participants. The practice increased household food availability, reduced living costs, and generated additional income, strengthening local economic resilience. However, challenges remain, including limited technical skills, financial constraints, and inconsistent government support, and the study concludes that strengthening training programs, improving access to finance, and developing pilot projects are needed.

A discussion piece examines opportunities for cooperation on food security and sovereignty between Cuba and the Republic of Korea following the reestablishment of diplomatic relations between the two countries. It highlights the importance of a legal framework recognizing healthy, adequate nutrition as a fundamental right, and identifies urban agriculture — an area of success for both nations — as a key strategy for pursuing sovereign, local, and sustainable food systems. The piece frames this as an opening for scientific diplomacy grounded in mutual respect and long-term partnership, presenting no empirical data or measured outcomes.

A report by Dr. Hossain discusses the transformation of organic farming through technological, ecological, and social innovation, citing examples including precision farming, community supported agriculture, biological pest control, and digital traceability systems. Case studies of an organic sack-garden for household nutrition, integrated rice-duck farming for pest control and soil health, and a Zero Energy Cold Chamber (ZECC) for post-harvest storage are described as demonstrating low-cost, replicable models that improved smallholders' incomes and sustainability. The report cites the Asian Productivity Organization's "Green Productivity" framework as linking productivity gains with environmental stewardship across the Asia-Pacific region.

Drawing on an analysis of recent crises in Brazil—transportation strikes, floods, prolonged droughts, the pandemic, currency fluctuations, and international conflicts—that exposed fragilities in the food supply chain leading to food insecurity, food deserts, and shortage risk, this study proposes urban food self-sufficiency strategies using nationally and internationally recognized urban agriculture techniques. It examined hydroponic cultivation and vertical farms through technical site visits, literature review, and interviews with managers and nutritionists, defining the built and cultivable area needed to guarantee a minimum survival diet for an estimated population, and, given the relevance of energy consumption to final food cost, incorporated solar power installations sized to different demand levels to reduce grid dependence; the plan was conceived initially as an alternative system with potential to evolve into a redundant, mitigating system.

A qualitative, exploratory-descriptive study based on bibliographic and documentary review examines urban agriculture as a socio-environmental alternative to the contradictions of the Green Revolution. Drawing on classic and contemporary national and international literature and reports from multilateral bodies such as the FAO and UN-Habitat, it characterizes the Green Revolution as having raised agricultural productivity while deepening social inequality, homogenizing crops, and causing serious environmental impacts. It positions urban agriculture as valuing production diversity, strengthening community autonomy, and fostering new forms of sociability, concluding that examples across different contexts converge in strengthening food sovereignty, social inclusion, and urban sustainability.

A study of how 150 urban pearl millet farmers aged at least 40 in Commune V of Niamey — an area the authors note is often overlooked in agricultural studies, since most work focuses on broader farming systems — perceive climate change and what they do about it. Respondents were reached by snowball sampling; data came from structured interviews, focus group discussions and key informant interviews with the Agricultural Extension Unit, alongside an analysis of 30 years of rainfall data (1991-2020). Farmers showed a high level of climate awareness over the past 30 years and had adopted both local and extension-based adaptation measures, and significant disruptions in rainfall were confirmed in the record. The adaptation strategies used were soil fertility regeneration techniques, crop diversification, crop defence, improved seeds, organic fertilizers, adjusted planting calendars, water conservation techniques, and prayers or rituals. Descriptive statistics, statistical tests and multinomial logistic regression were used to identify the determinants of adoption.
