This article analyzes the recalibration of justice for agrarian communities along the Yamuna in Delhi. Following a 2015 ban on edible crop farming by India's apex environmental court, the Delhi Development Authority has conducted multiple demolition drives for nearly a decade to evict farmers and clear land for redevelopment. The ongoing contentions involving farmers, planning agencies, and the judiciary in this region are symptomatic of the erosion of social justice in urbanizing India.

This bibliographic review identified the main problems of urban agriculture and actions for sustainability. The study found that the primary deficiencies in urban agriculture are inadequate management practices, a lack of organization, and absent or inefficient public policies. Key leverage points for change include agroecology, policies for land access and sustainable financing, and dissemination processes.

This paper examined two housing authority-led urban agriculture projects in New York City and Denver, Colorado, highlighting their multidimensional benefits such as skill-building and community cohesion. While these projects improved residents' daily experiences, the study noted that social problems persist despite new interactions. The analysis emphasized the need to consider both stated and implicit goals in urban agriculture ethics, acknowledging that attempts to harmonize competing claims are at the root of urban agriculture practices.

This study discussed the significance of the new urban garden movement for sustainable urban restructuring, focusing on community garden practices over the past two decades. It examined how the movement is integrated into the governance of urban climate crisis policies, how it utilizes this framework, and to what extent the autonomy of gardens as free spaces and commons can be maintained under these circumstances. The findings suggest that the autonomy of urban gardens may be difficult to maintain when integrated into climate crisis policy governance.

This paper presents a methodology applicable to sustainable community actions, developed from seven years of experience with low-income communities in a Brazilian community garden. The methodology is based on participatory action research, systemic design, agroecology, food sovereignty, and solidarity economy principles. The study demonstrates the importance of integrated work among the elements of the quintuple helix model (society, government, industry, academia, and environment), but it does not detail specific challenges or limitations regarding governance.

In Kampung Ngemplak Sutan (Kampung Sayur Organik), Surakarta, Indonesia, sustainability of the local urban farming initiative was evaluated using primary data from observation, questionnaires and interviews plus secondary data, analyzed with Multidimensional Scaling and Rapid Appraisal for Sustainability (MDS/RAPS). The socio-cultural dimension scored highest at 75.44 ("very sustainable"), while the economic dimension scored lowest at 56.71 ("fairly sustainable"); the study also noted that urban farming there functions mainly as a side activity that receives limited attention and that community participation has been declining.

This study examines the disappearance of a historic urban agriculture landscape in Bangalore, India, between the 1950s and 1970s, a period of post-independence urban planning, drawing on urban planning documents, government files and oral histories recorded with the Vahnikula Kshatriya, a traditional urban agriculture practitioner community. It finds that colonial frameworks embedded in post-independence urban development plans not only displaced urban agriculture but continue to affect it, and argues for changing how urban planning in formerly colonised places approaches urban agriculture.

A study of a Sharing Community Supported Agriculture (CSA) farm in China examined, through semi-structured interviews and thematic analysis, how external investment drives the conventionalization of alternative agriculture. The farm's low economic sustainability was the trigger that drew in external investment; investors then compelled the farm manager to relax adherence to organic agriculture's ecological values and principles and shift toward specialized, intensive farming to secure profitability, and a new business model was adopted that further entrenched this conventionalization.

A chapter examines the role of technology across the European 'agrifood' system, an umbrella term for the agriculture, horticulture, food, and drink sectors. Placing the dysfunctional consequences of making economic growth the driver of food-system organization in historical context, it shows through a case study of a daffodil farm in South West England that when technology is deployed as an engine of efficiency, unbridled growth, and profit maximization, it vastly improves productivity through worker quantification—time, motion, and output tracking—while transforming worker-nature relationships in exploitative ways. By contrast, when used to prioritize non-exploitative, collaborative relationships, technology can support sustainable well-being and ecological production, illustrated through three alternative food network cases: a UK community garden, a UK Community Supported Agriculture scheme, and a network of social agricultural cooperatives in Italy.

A review combining scientific literature analysis and interviews with urban farmers examined urban farming models including community, indoor, rooftop and vertical farms using techniques such as aeroponics, hydroponics and aquaponics. It found that sustainability and yield remain major challenges to fully realizing urban farming's potential, identifying limited land and water resources, pest and disease incidence, financial constraints on setup and maintenance, knowledge and skill gaps among participants, and a lack of effective collaboration between universities, government and industry as the key barriers.

Two years of monthly water sampling and hydrological monitoring at the outlet of the Wadi Guenniche watershed (86 km², with rainfed cereal, legume and orchard cultivation and irrigated market gardening) in northern Tunisia, a tributary of the Bizerte coastal lagoon, tested for 469 pesticide active ingredients and metabolites. Twenty-nine pesticide active ingredients and 2 metabolites were detected in the water, 24 of which are authorized for use in Tunisia; 14 of the authorized substances had never before been mentioned in farmer surveys. The five most frequently detected herbicides and metabolites were AMPA (100%), glyphosate (94%), simazine (94%), 2,4-D (70%) and deisopropylatrazine (DIA, 47%). The detection frequency and concentration range suggest phytosanitary pressure and water contamination comparable to the northern Mediterranean shore, indicating a need for further study of pesticide use and fate on the southern shore, particularly in Tunisia.

This chapter investigates urban agriculture in Singapore through a political ecology lens, examining food security from the perspective of traditional commercial farmers. Growing urban food demand and risks inherent in reliance on the global food system have spurred city governments to implement diversified strategies for integrating urban agriculture at different scales; Singapore, a high-earning city-state that imports 90% of its food, has set a target of raising domestic food production to 30% under its Singapore Green Plan 2030 "30 by 30" Grow Local target. The chapter questions whether this level of food independence is achievable if food production shifts away from traditional farming toward high-tech operations such as rooftop or vertical farms. Semi-structured qualitative interviews covered four topics: general farm practices, social networks, benefits and barriers, and livelihood alternatives. Findings were examined in the context of a rising generation of high-tech entrepreneurial farmers facing the challenge of meeting consumer demand against land and labor scarcity. The in-depth case study demonstrates that technology is only one driver, among many, of the sustainability of the local food system in Singapore, and traditional commercial farmers face pressure on their livelihoods as policy shifts toward high-tech production.

Treated wastewater from the plant serving Bole Lemi Industrial Park (BLIP) in Addis Ababa, Ethiopia was sampled at the treatment plant's influent and effluent and analyzed using a treated wastewater quality index (TWWQI) to assess suitability for urban irrigation agriculture. The aggregate TWWQI classified the water as 'very poor' for urban irrigation agriculture, with heavy metals contributing 85% of that grade, nutrient load 4%, salinity 8%, and miscellaneous contaminants 4%. Discrete indices varied: heavy metals scored 'very polluted', nutrients 'excellent', salinity 'poor', and miscellaneous contaminants 'good'. Contaminant removal efficiency ranged from 30% to 100% (58% in aggregate), and some contaminants showed higher concentrations in the effluent than the influent, indicating the treatment plant failed to remove them. Cr3+, Cl− and TDS contributed most to the poor rating, and the plant was found to need upgrading to increase removal efficiency.

This paper argues that widely publicized figures on urban agriculture's environmental impacts lack the methodologically sound evidence needed for valid comparison, before conclusions can be drawn. It addresses problems in comparatively assessing environmental performance between rural and urban farming and argues for the need for specifically designed indicators capable of comprehensively assessing multifunctional urban agriculture.

This chapter examines the dominant convention in critical agrarian studies and agrarian movements — that land struggles are best captured by an agrarian-reform framework of expropriating land from large private monopolies for redistribution to landless and near-landless working classes. It argues that while this type of struggle remains important, it does not fully capture the range of land struggles of working people across rural and urban, agricultural and nonagricultural spaces. Over recent decades the working classes have fragmented, as the numbers of people combining agricultural/nonagricultural and rural/urban livelihoods have vastly expanded, decentering working people's land struggles from the classical treatment tied to agriculture and capitalism. Land struggles today are dispersed and multisited, with political leadership and power that are polycentric rather than unified, and span multiple scales.

Using a GIS-based risk assessment methodology, this study develops a quantitative food-insecurity scale for the most vulnerable urban populations, calculating risk as a combination of social vulnerability and hazard (difficulty of access to food distribution), and applying the model to two case studies: southeast Washington, D.C., in the United States and Puente de Vallecas in Madrid, Spain. A Social Vulnerability Index was computed from average income, education level, unemployment rate, and age, while hazard values were derived from proximity to supermarkets. The analysis identified high-risk food-insecurity areas in both neighborhoods requiring urgent intervention measures. In Puente de Vallecas, census tract 07913143 was identified as a high-risk hotspot with a Social Vulnerability Index of 1.646495 (range 0.901–3.223) and a risk value of 3 (range 3–10); in southeast D.C., tracts 7601 and 7605 were selected as high-risk zones for further study, with Social Vulnerability Index values of 2.221 and 1.737 (range 1.040–3.525) and risk values of 2 and 5 (range 0–10), respectively. The study also identifies a general shortage of areas combining residential and commercial use and limits on public transport availability in the food-insecure urban areas studied.

In New Jersey, 50 food desert areas face the most severe food insecurity across both rural and urban contexts. This study identified nine barriers to implementing urban agriculture initiatives in New Jersey's urban food deserts, using a sequential quantitative analysis combining a survey of food systems professionals with a GIS-based spatial analysis to identify the most prevalent barrier. Working in partnership with New Jersey urban agricultural organizations, the study found that lack of funding was the most commonly cited barrier to expanding urban agriculture initiatives. The GIS-based spatial analysis found that high-priority barriers varied by region, but that all organizations identified funding, or lack of access to funding, as a significant barrier regardless of whether they operated in a low- or high-income neighborhood. The study concludes that policymakers must reevaluate the role of urban agricultural organizations in New Jersey's urban food deserts.

This chapter surveys the food-security implications of agricultural land use, unsustainable features of widespread food production practices, and the debate over agricultural intensification versus extensification, then examines land use's consequences beyond the land itself for groundwater, surface water, oceans, ambient air quality, and planetary systems. It explains the causes of forest destruction and fragmentation driven by the global expansion of land used for "high-risk commodities," the linkage between deforestation and declining terrestrial biodiversity, and the global market dynamics driving both crises. It assesses socioeconomic and ecological shortcomings in some proposed nature-based solutions, showing that they perpetuate an unsustainable business-as-usual approach, and summarizes how these land-use issues are conceptualized as human-rights concerns and translated into policy proposals.

This book chapter combines bibliographical and topical analysis of scholarly and gray literature with case studies from Middle East and North Africa (MENA) countries to examine the state of urban and peri-urban agriculture (UPA) amid regional climate pressures — rising temperatures and frequent droughts damaging limited water resources and threatening agriculture and food security. The chapter reports that UPA in the region lacks adequate infrastructure and resources, including access to water, suitable land and equipment, and that in many MENA cities, the absence of government initiatives combined with land tenure problems and high land prices makes UPA less prevalent and less viable; it concludes that improved policy support and enabling regulations — including zoning rules and financial and technical support — are needed to expand UPA in the region.

Using a hybrid approach combining the HYSPLIT and AgDRIFT models, this study estimated organophosphate pesticide spray drift from corn and soybean fields into urban-agricultural interface communities in Sangamon County, Illinois, at both field and county scales. Preliminary findings indicate that all residential areas near agricultural land are at risk of pesticide drift, since buffer zones do not exceed 25 meters; of 34 water bodies (rivers, lakes, streams, and drains) within the 30,200-acre study region, 12 fall within the high-drift zone, and roughly 106 buildings across an estimated 10,300 km² were found to have potential exposure to drift.

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 study assessed heavy metal contamination in 96 surface sediment samples collected from urban, agricultural, and forested areas of the Bug River catchment in Poland between July 2018 and 2020, measuring metals (Zn, Pb, Cr, Ni, Cu, Fe, Mn, Cd) by atomic absorption spectroscopy and applying the geoaccumulation index (Igeo), contamination factor (CF), and pollution load index (PLI). Urban sediments showed significantly higher heavy metal concentrations than agricultural or forested areas, with cadmium reaching up to 2.5 mg/kg; the average Igeo for cadmium was 0.24 in agricultural areas and 0.15 in urban areas, while the highest PLI values, reaching a maximum of 0.33, occurred in urban areas, and statistical analysis showed both urban emissions and agricultural activities significantly influenced heavy metal presence in the sediments.
