This descriptive study, using purposively sampled primary data from 30 farmers in Danurejan sub-district and 25 farmers in Jetis sub-district, Yogyakarta City, Indonesia, examines the contribution of urban farming income to household income through farm income analysis, a one-sample t-test, household income analysis, and multiple linear regression. Urban farming produced a positive annual income (Rp 112,883/year), but its contribution to total household income (Rp 46,579,988/year) was only 0.24%. This low share was attributed to the very small quantity of crops cultivated per household — for example, 4 polybags/year of bird's-eye chili, 10 polybags/year of large chili, and 11 polybags/year of mustard greens. Farmer age, education level, quantity of crops grown, and seedling price were the factors significantly affecting urban farming income.

오익근, 서정아, 장승옥 · 한국지역개발학회지 · South Korea

A focus group interview with young urban farmers in Daegu, South Korea, explored job creation through urban farming. Participants perceived farming as physically demanding and unrewarding, despite seeing urban farming as a promising industry for job creation. They also noted a lack of national support policies and difficulties in participation. A contradiction was identified between the young farmers' desire to adopt labor-saving new technologies and the goal of creating jobs through traditional farming.

Marina Silalahi, Lauresius Sihotang, Sunarto Sunarto, Fajar Adinugraha, Adisti Ratna Puri · · Indonesia (Cianjur)

A survey was conducted among 21 students at Pusaka Junior High School in Cianjur, Indonesia, to assess their understanding of hydroponic farming. Students knew the definition, methods, maintenance, and production of hydroponic plants, but literally interpreted that media like sand could not be used. While many students had experience with hydroponic farming, they claimed it was more expensive than conventional farming.

Mohammad Rondhi, Pravitasari Anjar Pratiwi, Vivi Trisna Handini, Aryo Fajar Sunartomo, Subhan Arif Budiman · Land · Indonesia (East Java)

This paper investigated the inter-relationship between land economic value and agricultural land conversion (ALC) in East Java, Indonesia. It calculated the land economic value for agricultural and non-agricultural (housing) uses in two areas: a peri-urban agricultural area facing rapid urbanization and a rural agricultural area with zero ALC. Results showed that agricultural land yielded a higher economic benefit in rural areas, whereas in urban areas, housing yielded a value seven times higher than agricultural land.

Hok Bun Ku, Yan Hairong · · China

China's food-security crisis, caused by unsustainable development, has diminished the country's farmland through large-scale land acquisitions, ecological restoration projects, agricultural structural adjustments, natural disasters, and pollution, among other factors. This chapter argues that local producers and consumers are not passively waiting for government policy changes but, organized by green social workers, are actively searching for alternatives to achieve self-sufficiency and food security through a new initiative called the "rural–urban alliance." Framed within the social economy perspective advocated by green social work as a way to rethink economic development and consider alternatives to capitalism, the rural–urban alliance and community-supported agriculture (CSA) are positioned as a potential new route for China's sustainable development that could change the pathway of economic development forms that cause inequality and undermine livelihoods. This is a proposed, forward-looking argument, however; the abstract does not report empirical evidence that CSA or the rural–urban alliance have actually mitigated the food-security crisis.

Abdullah, Abdullah, Gufran Darma Dirawan, Nurlita Pertiwi · Eprints (Universitas Negeri Makassar) · Indonesia (Makassar)

A study analyzing the sustainability level of urban farming in Makassar City, Indonesia, found that the overall urban farming sustainability index was 48.52%, indicating a "less sustainable" status. The ecological dimension was rated 42.66% as "less sustainable," while the economic dimension was 50.69% as "fairly sustainable."

A. Husni Malian, Masdjidin Siregar · Forum penelitian Agro Ekonomi · Indonesia

This paper discusses the dwindling role of peri-urban agriculture in Indonesia due to urban development policies favoring manufacturing and service sectors. The economic crisis and policy changes had different effects on farmers of leafy vegetables, orchids, and ornamental plants. Increased fertilizer prices and wage rates, coupled with decreased demand for orchids and ornamental plants in 1999, reduced farmers' income. Conversely, increased demand for leafy vegetables led to more intensive land use, neglecting health and environmental concerns.

Rusida Rusida · Plano Madani : Jurnal Perencanaan Wilayah dan Kota · Indonesia (Belopa)

A study in the urban area of Belopa, Indonesia, assessed the potential for urban agriculture, identifying suitable land for various crop types and key commodities. However, the research found that extensive housing development, particularly on the outskirts, and limited land availability mean not all land can be developed for urban agriculture. Urban agriculture supports food security, and public and government perceptions influence future land plans.

Wen-jiang Li, Linjun Li, Guoyu Qiu · Journal of Integrative Agriculture · China (Shenzhen)

Water and electricity-use patterns in Shenzhen, South China, were analyzed from 2001 to 2009. Water and electricity use per GDP in agriculture was the highest among sectors, indicating inefficiency. Traditional agriculture in Shenzhen will not be sustainable during urbanization and industrialization, except for high-tech intensive agriculture with low water and energy costs, and has been gradually substituted by industry, construction, residential life, and services.

These issues restrict the range of agricultural management.

Zhigang Wei · Journal of Qingdao Agricultural University · China

A comprehensive survey of agricultural structure and layout in Qingdao, China. It states the sector has achieved transformation and upgrading, with growing agricultural industrialization and increasingly optimized layout of agricultural areas approaching cluster-scale planting and breeding industries. However, it reports that further adjustment of planting structure faces major bottlenecks due to limits on arable land and food security: the traditional small-scale fish-farming model seriously restricts further development of animal husbandry and aquaculture, and fluctuating agricultural product markets combined with a lack of competitiveness are affecting the agricultural industry's layout. It concludes that crop structure needs further adjustment, that production should be scaled up, specialized and standardized, and that urban agriculture should be emphasized to expand agricultural functions.

이민수, 박덕병, 황대용 · 농어촌관광연구 · South Korea

A cost-benefit analysis of Sunchang County's 2007 pilot "allotment garden with log house" program (family farm-stay plots), launched by South Korea's Rural Development Administration in JeonBuk Province, using the county's internal records and interviews with project managers. The analysis found the program to be an inefficient business with a weak cost-benefit structure that produced a negative net benefit: at an assumed 6.5% discount rate, net present value was estimated at -262 million won, with a benefit-cost ratio of 0.70 and an internal rate of return of 2.7%. The authors nonetheless conclude the program is worth maintaining as part of the government's balanced regional development policy.
