Using mathematical and econometric methods, an ecological security evaluation index system for urban agriculture in Shanghai was constructed for quantitative and comprehensive assessment. From 1993 to 1998, the agricultural resources security index was stable while the agricultural environment security index fluctuated, the agricultural socio-economic development index declined slightly, and the comprehensive agricultural ecological security index rose and fell in turn; from 1999 to 2008, after a small decrease from 1999-2004, the resources security index grew at an annual rate of 10.43%, while the environment security index, socio-economic development index, and comprehensive index grew at annual rates of 6.97%, 24.65%, and 6.88% respectively. By 2008, per-capita cultivated land in suburban districts, fertilizer application intensity per sown area, the ratio of agricultural comparative advantage, per-capita grain in rural areas, and the frequency of acid rain had become major limiting factors with obstacle degrees below 10.00%, with threats mainly originating from the agricultural resources and environment subsystem while the socio-economic development subsystem's negative influence diminished year by year.

International experience indicates that the development of ecological urban agriculture is inseparable from the rise of a middle-income group, characterized by taking responsibility for social stability, holding non-extreme policy positions, and — in consumption — emphasizing environmental protection and advocating green consumption. The paper argues that urban agriculture must foreground an ecological theme to attract this middle-income consumer group, gain support from a consumer base of sufficient scale, and allow the multifunctionality of ecological urban agriculture to be realized and exercised.

This 2011 article profiles a rural credit cooperative in Fucheng District, Mianyang, Sichuan Province, China, located at the urban-rural fringe in an area experiencing rapid urban-rural integration. Amid the Chinese Communist Party central government's Document No. 1 policy focus on rural issues, and as three rural issues (agriculture, rural areas and farmers) and agricultural industrialization advanced, central and regulatory bodies adjusted requirements and policies for financial institutions supporting these areas. The Fucheng District Rural Credit Cooperative, following the principle of supporting local economic development and aligning with local agricultural industrialization projects and structural adjustment plans, seized these policy opportunities and served as a leading force in agricultural support, achieving three shifts — including a shift from supporting rural village agriculture toward supporting urban, suburban and export-oriented agriculture.

Based on a survey of 30 green roofs created between 2002 and 2004 by the Seoul Metropolitan Government, this study analyzed the properties needed to reclassify green roofs into three types via cluster analysis. The previous classification, based on structural safety diagnosis type and visual expert judgment on site, was found to require correction. Results showed that the concepts of "rooftop garden" and "green roof" differ from those in previous studies: intensive green roofs referred to as rooftop gardens were closer to integrated management, while green roofs were closer to low management. Reclassification of greening types was also carried out using categorical regression analysis, which extracted factors influencing greening type; the analysis's R-squared value was 95.2%. This result indicated that rooftop gardens are places demanded for high levels of human activity.

A study of 30 green roofs created by the Seoul Metropolitan Government between 2002 and 2004, using cluster analysis to reclassify them into three types. The prior classification, based on structural safety diagnosis and on-site visual judgment by experts, was found to need correction. The study redefines the concepts of rooftop garden (intensive green roof) and green roof differently from earlier studies, positioning rooftop gardens as closer to integrated management and green roofs as closer to low management. Categorical regression analysis was also used to extract the factors influencing greening type, with an R-squared of 95.2% for the regression's explanatory power. The results indicate that rooftop gardens are spaces expected to support high levels of human activity.

A South Korean study examined the functions and roles of a Green Community Rediscovery Center (GCRC) in terms of community integration, designed a GCRC incorporating various green roof types, and investigated applying a renewable energy system (e.g., PV) to building greenery. Four functional modules were proposed: an ecopark and community gardens with environmental education programs, a green housing model with education programs, a Discover Science Center, and a green business model with education programs. In design terms, three main functions were presented: community garden functions; establishment of a green business model, community composting system, and urban farming system; and the role of community gardens in social interaction within the GCRC. Air temperature on the green roof (using Sedum sarmentosum as cover) was about 3°C lower than on a non-green roof, indicating potential efficiency gains for PV systems. The study concludes that the proposed GCRC would raise neighborhood satisfaction and quality of life and contribute to social integration and community regeneration.

A correlational survey of farmers' attitudes toward participating in community-supported agriculture (CSA) in the Markazi district of Karaj, Iran. Out of a population of 1,598 farmers, a sample of 130 was drawn by simple random sampling (initially 117 via Cochran's formula, later expanded), using a questionnaire validated by expert judgment and showing Cronbach's alpha reliability of 0.7–0.9. Farmers' main motivation for CSA participation was securing financial resources and marketing their produce. Interest in receiving citizens' financial support correlated significantly and positively with annual income, family labor use, and number of citizen visits to farms (p<0.01), and with dependency on the residential area and education level (p<0.05). A Kruskal-Wallis test found significant differences among farmers from different residential areas in interest in citizen financial support, willingness to cooperate with citizens across income levels, satisfaction with farming income, and length of cultivation (p<0.05).

This study analyzed agricultural land use changes in peri-urban Yogyakarta from 1996-2007, covering 922.17 ha in Sleman, 1,888.60 ha in Bantul, and 1,082.79 ha across 47 villages. Factors like agricultural production exchange value, irrigated land, built area percentage, population density, education, and land price significantly influenced land change rates, which negatively correlated with distance from the city. However, agricultural land percentage to village area, land tax, and dummy variables for Bantul and Kulon Progo did not significantly influence these rates, and the changes negatively impacted regional food loss, availability, and farming sustainability prospects.
