This 2024 global review examined 96 studies focusing on methods for estimating carbon sequestration (CS) and emissions in urban and peri-urban agriculture (UPA). The review found significant research gaps: most studies were in the global north, research in the global south is lacking, and there are fewer studies on CS compared to GHG emissions. Additionally, few studies jointly assessed water and carbon cycles, and spatiotemporal analysis, modeling, and remote sensing for GHG emissions are underutilized.

This study investigated factors inducing the emergence, sustenance, and sustainability of urban agriculture using primary data from urban farming households in Kerala and Arunachal Pradesh, India. The research indicates that urban agriculture has provided questionable environmental gains and has not significantly improved urban food security, especially among the poorer sections.

Ashagrie Gibtan, Wondwosen Abera, Mekuria Delelegn, Molla Maru, Adamu Emiru · Ochrana prírody Slovenska/Ekológia · Ethiopia

Land Use/Land Cover (LULC) dynamics were analyzed in four Ethiopian cities—Addis Ababa, Hawassa, Bahir Dar, and Adama—over 17 years from 2006 to 2022. SPOT 5 and Sentinel satellite imagery, key informant interviews, focus group discussions, and field observations were used. Findings revealed a rapid expansion of urban built-up areas, primarily at the expense of peri-urban horticultural lands, which has an adverse impact on the sustainability of urban agriculture.

Anila Kausar, Viola Vambol, Sergij Vambol, Saima Sultana Sharfi · International Journal of Economic and Environmental Geology · Pakistan (Karachi)

This study conducted a Land Use Land Cover (LULC) analysis of Murad Memon Goth, a peri-urban area of Karachi, Pakistan, comparing data from 2013 and 2021. The results revealed a 9.6% increase in settlement sprawl, indicating significant encroachment on agricultural lands. Cropland area decreased from 38.86% in 2013 to 26.11% in 2021, highlighting a negative trend for peri-urban agriculture in the region.

Pierric Calenge, Maie Gérardot · Métropolitiques · United States (Cleveland)

The work by Max Rousseau and Vincent Béal illuminates the ambiguities of a policy that organizes urban decline and racial segregation in Cleveland. This policy promotes urban degrowth and racial segregation, balancing algorithmic management and urban greening. The study focuses on the Rust Belt region, which experiences de-urbanization marked by the subprime crisis, racism, and segregation.

Hydroponic farming, adopted in urban India to meet food demands, faces shortcomings including higher initial costs, complex nutrient discharge, and energy requirements for microclimatic conditions and skilled labor. To address these issues, a smart hydroponic farming architecture is discussed, aiming to reduce human intervention and water wastage using wireless sensor networks and IoT.

Cecil C. Konijnendijk · Edward Elgar Publishing eBooks · Global

This chapter examines the diverse uses of urban green spaces, encompassing recreation, biodiversity conservation, public health, and regulatory ecosystem services, with food production also re-emerging. Changing urban populations, including cultural diversity and ageing, have altered demands and uses. The study identifies a critical need to manage potential conflicts and trade-offs among these varied demands, despite many uses being able to coexist.

Meriem Korchi, Ouassila Bendjaballah · Indonesian Journal of Social Science Research · Algeria

This study assessed urban actors' perspectives on urban agriculture in Annaba, Algeria, and mapped agricultural activities to integrate them into urban policy. Interviews with decision-makers and farmers, combined with spatial analysis, revealed that while there is interest in urban agriculture, it is not effectively integrated into institutional and legal frameworks. Agricultural plots in cities are often reserved for future urban development.

Sarah Bell, Charlotte Johnson, Tse‐Hui Teh, Kat Austen, Gemma Moore · · United Kingdom (London)

This chapter explores co-design in developing urban infrastructures, presenting a six-step "Bottom-Up Infrastructure" model. The method was applied to a rooftop garden on a London social-housing estate, intended to function as drainage infrastructure. The case study revealed the potential for co-design, but also highlighted significant constraints on implementation in cities where communities possess limited power and resources.

Bernard Afiik Akanpabadai Akanbang, Millicent Awialie Akaateba, Prosper Issahaku Korah · Discover Cities · Ghana (Wa)

This exploratory cross-sectional survey in seven rapidly growing neighborhoods in Wa, Ghana, administered 285 questionnaires to residents to understand motivations, challenges, and constraints of home gardening. Results showed 56% of respondents had gardens, primarily motivated by beautification (56.1%) and food production (52.3%). Limited space (49%) and busy schedules (34%) were identified as main barriers. The study found that while garden ownership aligned with the autonomy need, the relationship need, which correlates with environmental motivations, was notably low among residents. This indicates a limited effect of environmental awareness on home gardening motivation in the surveyed population.

This study evaluated land cover change and its drivers using spatial and statistical analysis in 22 designated protected areas (PAs) across the tropical coastal regions of sub-Saharan Africa. Results indicated that food production is prevalent in these protected areas regardless of their designation, and forest loss occurred in most PAs, suggesting weak conservation. Population density was the most significant driver of land cover change, and only 15 out of 22 protected areas showed an increase in their total ecosystem service value.

Cavani Guzmán, Pierina · Macedonian Journal of Medical Sciences (University of Skopje) · Peru (Lima)

This article discusses the impact of urbanization and industrialization processes on peri-urban agricultural production in the Nuevo Horizonte de Carapongo association in Lurigancho, Lima, Peru. The research analyzes the development of these phenomena and their relationship with the changes generated in the agricultural production of the area, contributing to the academic discussion on the deagrarianization process of peri-urban spaces.

Ahmed Alhuseen, H. M. A. M. Omer, Eva Pauditšová, Hussein M. Sulieman, Mária Kozová, Pavel Cudlín · · Sudan (Khartoum)

A study assessed spatial accessibility disparities and users' opinions regarding public green spaces (UGSs) in Khartoum State, Sudan. Using GIS and questionnaires, it evaluated potential accessibility to 44 urban parks, community gardens, and city forests within 5, 10, and 15-minute travel intervals. Results showed inequitable access opportunities to UGSs, primarily favoring first-class residential areas. Within a 5-minute walking interval, the UGSs service zone covered less than 1% of the population. User opinion assessment revealed that 80% of parks required entrance fees, and the study concluded that UGS accessibility does not correspond to international quality of life indices.

This study investigated the quantity, composition, and disposal practices of domestic waste in Bukavu City, Eastern D.R. Congo. Findings revealed significant challenges in waste management infrastructure and practices, showing that approximately 5% of waste undergoes composting, while 10% is used as livestock feed, 66% incinerated, and 17% buried. Waste management is primarily handled by children (82%), with very limited involvement from non-governmental organizations.

Dongxiang Chen, Yuanming Wang, Haijun Bao · Habitat International · Global

This research extended the land sharing and sparing framework to urban land use, quantifying the impact of urban services, food production, and ecosystem services. The results showed that land-sparing scenarios had a 23.6% lower overall value loss than sharing scenarios on average. However, while land-sparing mitigates losses in food production and ecosystem services, it increases the cost of urban services, creating a trade-off that challenges achieving an optimal win-win situation.

Ann-Kristin Steines, Michele D’Ostuni, Anna Wissman, Kathrin Specht, Chiara Iodice, Runrid Fox-Kämper, Francesco Monticone, Isabella Righini, Véronique Saint-Gès, Antonella Samoggia, Francesco Orsini · Cities · Europe

This research addressed international and national policies, as well as related constraints and challenges affecting City Region Food System (CRFS) development in six European countries. Data was collected through desktop research, stakeholder interviews, and a workshop. The study found that planning laws restrict possibilities for food production in cities, and legal frameworks prevent the marketing and sale of food produced by non-commercial actors or informal farmers. It also identified a need to expand vocational training in the agricultural sector.

Rini Fitri, Achmad Yozar Perkasa, Hinijati Widjaja, Olivia Seanders, Reza Fauzı · Tekirdağ Ziraat Fakültesi Dergisi · Indonesia (Jakarta)

This research evaluated the sustainability of urban farming development in Petamburan, Central Jakarta, using a descriptive qualitative methodology and Multi Dimension Scaling (MDS) approach. While urban residents generally have knowledge and support for urban agriculture, the analysis of four dimensions (ecological, economic, social, technological) indicated that urban farming in Petamburan is not sustainable. The sustainability index was very low, categorized as destructive and unsustainable across ecological (14.55%), economic (13.85%), social (13.94%), and technological (13.43%) dimensions.

This study analyzed the spatial structure, plant diversity, propagation strategies, and ecological functions of domestic gardens across three distinct neighborhoods—planned, unplanned, and residential—in Lubumbashi, DR Congo. The study identified 232 taxa across 68 families, with exotic species predominating in all neighborhoods (80%), especially in unplanned areas (82.25%). This dominance of exotic species highlights a potential for ecological imbalances and emphasizes the strong human influence on domestic gardens in Lubumbashi.

Rob Roggema, Aleksandra Krstikj, B. J. Erazo Flores · Nutrients · Mexico (Monterrey)

This study in the Noreste of Mexico, focusing on Monterrey, investigated spatial and non-spatial barriers to adopting healthy diets and accessing plant-based foods. Findings revealed significant disparities in food access across the Monterrey metropolitan area, with central urban zones having superior access to fresh foods compared to suburban and peripheral regions. This inequality disproportionately affects marginalized areas with higher poverty rates, worsening food insecurity.

Juan Camilo Fontalvo-Buelvas, María Teresa Pulido Silva, Miguel Ángel Escalona Aguilar · Bitácora Urbano Territorial · Global

A bibliographic review identified that the main deficiencies in urban agriculture are inadequate management practices, a lack of organization, and absent or inefficient public policies. The study suggests that agroecology as a management system, policies for land access and sustainable financing, and dissemination processes are key leverage points for driving urban agriculture towards sustainability.

Ricardo Jacobs · Oxford University Press eBooks · Global

This chapter argues that rapid urbanization and global capitalism are destroying established livelihoods faster than creating new ones, leading to a growing surplus population. Dispossessed rural classes are reproducing themselves in urban spaces and converging with wage laborers to create agricultural livelihoods in cities of both the global South and North. This makes urban agriculture an important arena for land struggles and a livelihood option, shaping urbanization and socioecological relations.

Ronald O. Muchelo, Thomas F. A. Bishop, Sabastine U. Ugbaje, Stephen Akpa · Land · Uganda (Kampala)

This study examined urban growth and agricultural land loss in Kampala (1989-2015) and Mbarara (2002-2016), Uganda, using multi-temporal Landsat imagery. Kampala's urban area surged from 7.14% to 55.10%, and Mbarara's from 6.37% to 30.95%, while agricultural land decreased significantly in both cities. A substantial portion of urban growth encroached upon agricultural land (66.7% in Kampala, 57.8% in Mbarara), and unsustainable practices also converted wetlands and forests to agricultural land.

Nuriah Yuliati, Eko Nurhadi, Dita Atasa, Stevi Putri Afdolvina Baik · Jurnal Ilmiah Manajemen Agribisnis · Indonesia (Surabaya)

This qualitative study analyzed urban farming business innovation in Surabaya, Indonesia, using the Business Model Canvas (BMC) model across five Women Farming Groups (KWT) and Farmer Groups (Poktan). Findings showed that KWT Guyub Rukun had the lowest revenue, while Poktan Serpis had the highest. The study concluded that low revenue was due to income solely from crop sales and having only one main partner, indicating a limitation in revenue streams for some groups.
