This study investigates the decline of agricultural land in Guersif City, Morocco, due to rapid urbanization. Sociological surveys and technical data from 1954 and 2021 were used to identify and quantify the rate of agricultural land loss. The preservation of urban agriculture in Guersif faces a real challenge from other, more profitable activities.

Farhang FaghihLarijani, Elaheh Amani Vamarzani · DOAJ (DOAJ: Directory of Open Access Journals) · Iran

This study investigated whether an independent legal system exists in urban areas of Iran to recognize, maintain, and develop urban agriculture. It found that despite urban laws recognizing agricultural activities, legislators have not enacted a comprehensive law specifically for urban agriculture, nor explicitly included it in urban land definitions. The study hypothesized that a primary challenge is the lack of a compatible legal framework.

Paula Mota Santos · Social Inclusion · Portugal (Porto)

Grassroots urban horticultural plots (hortas) in the Porto Metropolitan Area, Northern Portugal, are informal communities that have existed for decades, often involving over 20-30 people. However, these low-income urbanite horticultural communities are not cherished by city governance, which does not prevent their destruction. This incompatibility between urban governance and grassroots communities hinders the right to the city for the low-income urbanites who created them.

Market gardening in Kinshasa's urban and peri-urban areas faces multiple constraints, including land insecurity, low natural soil fertility, the incidence of diseases and pests, weak technical support, climate hazards, poor input supply, and problematic marketing systems. These constraints limit yields in production sites and hinder the development of market gardening activities.

Matthew L. Richardson, John Taylor, Megan J. Thompson, Anusuya Rangarajan, Mamatha Hanumappa, Neith G. Little · PLoS ONE · United States (Northeastern United States)

This online survey of 394 urban growers, primarily in the Northeastern United States, profiled growers and assessed urban agriculture's state, identifying needs and challenges. Most growers were white (non-Hispanic), under 45, well-educated but without agriculture degrees. Urban agriculture was dominated by small non-profits and home/community gardens. A critical finding is that urban growers face diverse barriers, with the most common being land availability and long-term access in urban areas, and many reported low revenue or operating at a net loss.

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.

Aji Saputra, Oekan S. Abdoellah, Gemilang Lara Utama · Local Environment · Indonesia

A commentary on the current state of urban agriculture implementation in large Indonesian cities, the initiatives underway and the mechanisms for pursuing stated goals. It identifies land scarcity, inadequate urban agricultural infrastructure, financial constraints, and regulatory and administrative problems as the major obstacles to implementation. It also states that urban agriculture improves quality of urban life by providing fresh, healthy food and fostering community engagement, and cites Singapore, New York and Ghana as examples showing the importance of policy support, innovation and community involvement.

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.

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.

This study investigated changes in the urban farming community in Surakarta, Indonesia, using the AIDP model analysis approach, surveying 50 community members. Results showed varying success rates across strategy stages; evaluation strategies like partnerships with local traders and financial institutions, vertical land use, and open dialogue performed poorly. Furthermore, improving financial literacy and sustainable waste management systems were unsuccessful, and agricultural product brand promotion and innovative institutional models also performed poorly.

A literature review on the issue of agricultural land conversion to non-agricultural uses in Bekasi Regency, Indonesia, identified its direct impacts. The study noted reduced rice production, loss of fertile agricultural land, loss of investment in irrigation infrastructure, landscape damage, increased river and groundwater pollution, occurrence of natural disasters like floods and droughts, and a lack of water absorption areas. These findings indicate the need for policies and programs supporting sustainable urban planning.

Mohammed Seid Ebrahim · Ethiopian Journal of Business and Social Science · Ethiopia (Addis Ababa)

This study examined factors affecting the growth of micro and small enterprises in Gulele Sub-city, Addis Ababa, Ethiopia, using survey data from 120 enterprise leaders/owners. Enterprises grew at a rate of 0.20, but growth trends varied across sectors including urban agriculture. The analysis found that age, gender, and work experience of leaders/owners, along with enterprise age, employee numbers, workplace suitability, marketing problems, and government policies, significantly influenced growth, indicating that cumbersome bureaucratic procedures contributed to undergrowth and stagnation.

This exploratory review study examined the viability of urban food systems and their governance in Venezuela, based on secondary sources. While identifying available resources like educational infrastructure and a renewed legal framework, the study highlighted significant limitations. These include increasing deforestation, deteriorating potable water services for urban agriculture, migration of skilled populations, decline in public funding for science and technology, opaque official information, and scarcity of financing for new developments.

Kyunghun Min, Jisoo Ahn, Eunseok Lee · Journal of people, plants, and environment · South Korea

This study analyzed exemplary cases from the US and Canada to identify factors for the active use of rooftop greenhouses (RTGs) in Korea. Despite international interest in RTGs for carbon neutrality and food security, their implementation in Korea is limited by a lack of relevant legal bases and policies. Essential factors for stable RTG operation include long-term support, initial capital, differentiated distribution, and a review of laws and regulations, highlighting the need for legal and policy frameworks.

This article investigates "network failure" and collaboration barriers within Community-supported agriculture (CSA) networks in the UK and Germany, using qualitative case studies. The study found that CSA networks function effectively at national and local levels but experience relative failure at the regional level. Regular barriers to collaboration arise from capacity limitations, member differences, and competition, which the networks are actively trying to address.

The book "Urban Agriculture for Improving the Quality of Life. Examples from Bulgaria," edited by Donna Pickard, explores the real versus potential effects of urban agriculture on the welfare of urban and nearby communities. This multidisciplinary study analyzes the interplay between urban agriculture practices and quality of life through social, educational, economic, spatial, and ecological aspects. It also delves into the historical dimension of urban agriculture in Bulgaria, including examples from Sofia in the 1930s.

Cynthia Nneka Olumba, Eberechukwu Johnpaul Ihemezie, Chukwudi Charles Olumba · Climate and Development · Nigeria

This study aimed to understand urban farmers’ perceptions of climate change and the adaptation constraints they encounter in Anambra Metropolis, Nigeria. Household survey data using structured questionnaires showed that most urban farmers perceived climate change through effects such as increased weed infestation, drying up of streams/rivers, and decreased soil moisture. Principal adaptation constraints were diverse, falling within broader institutional, information, and financial categories. The study revealed that the socioeconomic conditions of urban farmers in developing countries pose a threat to urban agriculture's potential to mitigate climate change.

Mahyuddiin · KnE Social Sciences · Indonesia (Makassar)

This qualitative study analyzed the network structure of sustainable urban farming development policies in Makassar City, Indonesia, using observations, interviews, and documentation with stakeholders. The findings indicate that the network structure is not fully effective due to erratic, uneven, and unclear contact between actors, and a lack of binding written agreements in the trust dimension. However, information sharing and resource exchange dimensions are progressing well.

Seongeun Lee, Seongmin Shin, Hansol Lee, Mi Sun Park · International Journal of Agricultural Sustainability · Global

A systematic review of urban agriculture (UA) case studies identified conditions enabling and constraining UA development across different country income groups. For high-income countries, a lack of farmers' knowledge and urban development are significant challenges to UA implementation. Common requirements for all income levels include motivation, labor, policy, social capital, and arable land.

Agnes Naipospos, Raia Azzura · Journal of Sustainable Development and Regulatory Issues (JSDERI) · Indonesia

Indonesia faces a reduction in vegetable supply due to rapid urban development, and urban farming can be a solution to meet food needs, reduce household expenses, and increase farmer income. Using a normative juridical approach, this study indicates that Indonesia needs an urban farming program, but its current implementation is not optimal. Therefore, the Indonesia Masterplan for Future Urban Farming (IM-for-FUF) is introduced as an innovation expected to better support the implementation of the green economy.

Alioune Badara Dabo · Norois · France (Île-de-France)

This article analyzes how the public land tenure system, introduced in the 2018 "Agricultural Pact" in the Île-de-France region, articulates with local farming systems. Based on a qualitative survey conducted in the Green Belt area, the findings reveal that this land tenure system does not fully align with the strategies of farmers, particularly young people outside family farming who wish to establish themselves in agriculture, as they do not necessarily seek land ownership.
