Agnes G. Kapinga, Baraka F. Lenga · Urban Agriculture & Regional Food Systems · Tanzania (Dar es Salaam)

A qualitative case study in Dar es Salaam, Tanzania, using semi-structured interviews with 31 migrant farmers and seven key informants, revealed that migrant farmers contribute to urban food security through diverse crop cultivation and livestock keeping, enhancing food production and income generation. However, migrant farmers face major constraints including insecure land tenure, flooding, water scarcity, high input costs, and limited institutional support. City authorities institutionalize the marginalization of migrant farmers by treating urban agriculture as an informal and temporary activity, despite their critical contributions.

Muhammad Hussain, Saima Shaikh, Zahir Ahmad, Ihsanullah, George Kontakiotis, Andreas Dittmann · Ecological Questions · Pakistan (Multan City)

This study analyzed urban expansion patterns and their impact on agricultural land in Multan City, Pakistan, using remotely sensed data from 1990 to 2020. The built-up area increased from 75 km² in 1990 to 299 km² in 2020, representing an annual increase of 9.5%. This growth converted approximately 31% (100 km²) of fertile agricultural land into built-up areas, with predictions of further increases of 54% by 2030 and 67% by 2040.

Adomas Gedvilas, Dovilė Krupickaitė · Journal of Architecture and Urbanism · Lithuania

This paper examines old community gardens in Grigiškės and Plungė, Lithuania, as examples of Everyday Urbanism, using literature, data, maps, and interviews. The study found that these gardens, established informally on vacant land during the socialist period, are not officially recognized and their future development may differ due to varying local government attitudes. This highlights the need for a more flexible approach to their preservation and integration into urban planning.

Adan Iddrisu · DOAJ (DOAJ: Directory of Open Access Journals) · Ghana

This policy brief explored the causes of farmland loss and its effects on the livelihoods of smallholder farmers in the Northern Region of Ghana due to rapid urbanization. Using data from focus group discussions, findings revealed that loss of farmland reduces productivity, increases household food security vulnerability, and threatens the livelihoods of farmers.

Popov, Velian · reposiTUm (TU Wien) · Bulgaria (Plovdiv)

This study examines the disappearing phenomenon of informal urban gardening, known as Rancho, in Plovdiv, Bulgaria, focusing on its socio-historical factors. Despite its authentic, decades-long existence, Rancho is neglected and considered outdated, with a lack of legal regulation and its informal character endangering its future. The study proposes a gradual transformation of these areas into community urban gardens with new infrastructures to raise awareness and encourage authorities to reintegrate Rancho into the urban context.

Elias Nuwagaba, Murindwa Rutanga · East African Scholars Journal of Education Humanities and Literature · Uganda (Mbarara City)

This study explored how state-initiated, unplanned urbanization in Mbarara City, Western Uganda, affects the sustainability of urban farming and urban livelihoods. The research found that rapid, haphazard urban expansion, lacking strategic planning, has led to significant challenges. These include the emergence of slums, illegal land occupations, destruction of wetlands and riverbanks causing water pollution, and inadequate waste management, all negatively impacting public health and urban farming sustainability.

Joshua Zeunert, Scott Hawken, Josh Gowers · Land · Australia (Sydney)

A critical GIS analysis was conducted for Sydney and neighboring regions in NSW, Australia, to understand and advocate for Sydney's food production capacity. The study challenged the notion that Sydney's metropolitan landscape has low inherent biophysical quality for agriculture. Despite current metropolitan planning policy that marginalizes agricultural productivity, datasets revealed western Sydney is biophysically well suited for agriculture. Sydney's overall agricultural capacity was found to be comparable to five of six other coastal regions of NSW and superior to at least two, challenging current planning orthodoxy and policy.

Sarah Steinegger, Nora Katharina Faltmann · Journal of Political Ecology · Switzerland

This qualitative research examined the challenges consumers and farmers face in establishing proximity within a Community-Supported Agriculture (CSA) initiative in Switzerland that links rural mountain and urban areas. The study found that consumers and farmers are facing challenges in establishing proximity. Nevertheless, shared experiences of farming activities and social events, along with participants' willingness to improve CSA operations and strengthen ties for mutual understanding and joint efforts, contribute to the ongoing process of establishing proximity.

Henry Mensah · City and Environment Interactions · Ghana (Kumasi)

This study investigated adaptation practices and challenges among 85 urban farmers across three locations in Kumasi, Ghana. Farmers employed strategies like planting local crop varieties, expanding farms, and relocating. However, these strategies are hindered by institutional and technological limitations, financial constraints, lack of climate information, and delays in extension support, indicating significant governance challenges.

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.

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.

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.

Jennifer C. Franco, Saturnino M. Borras · Oxford University Press eBooks · Global

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.

This 2023 global systematic literature review examined peri-urban agriculture (PUA) as an ecosystem service, focusing on urbanization pressures and governance. The review found that PUA is crucial for urban areas in terms of food supply, ecology, biodiversity preservation, disaster mitigation, and recreation. However, massive urban expansion is a primary cause of PUA loss, and sociocultural biases have led to institutional constraints on peri-urban management within existing political and regulatory frameworks.

This study used geospatial techniques, multi-temporal land use maps, and population data to estimate urban land use efficiency (LUE), changes in built-up area per capita, and urban sprawl speed (SS) in the Sekondi-Takoradi Metropolitan area of Ghana. While LUE generally improved from 2002 to 2016, it deteriorated slightly between 2016 and 2021. Critically, agricultural land or grassland in the city has been converted to built-up land, posing a challenge for urban agriculture.

A critical literature review discussed the evolution of food and nutrition security (FNS) and the contributions of urban and peri-urban agriculture (UPA). The review found that institutional responses to FNS are concentrated in times of crisis, which favors the maintenance of globalized and unsustainable food systems. UPA practices show peaks of rise and decline, evolving with the FNS agenda.

Public urban agriculture (PUA) in the United States, Canada, the United Kingdom, and Australia faces challenges, including aesthetics and negative perceptions of its spatial presence and visual performance. In these contexts, PUA often remains limited to allotments, community gardens, education gardens, and street verge gardens, which frequently suffer from negative aesthetic perceptions in highly visible public settings. This chapter explores how eight distinctive rural food production practices could be translated into urban contexts to address aesthetic shortcomings in PUA design.

Amy Lawton, Nicky Morrison · Land Use Policy · Australia (Greater Western Sydney)

This study examines the drivers of peri-urban agricultural land loss in Greater Western Sydney, Australia, with a focus on the role of government agencies. It found that competing housing priorities and private market interests continue to take precedence over protecting agricultural land. The research indicates that this trend will persist unless the current pro-urbanization narrative and associated political priorities are altered.
