Multifunctional zoning optimization of agricultural land use by coupling Bayesian belief network with density peaks clustering – a case study in Guangdong, China
2026Hao Yang, Zijin Wang, Yueming Hu, Zhengxi Tan, Runyan Zou, L. Wang, Xiaoyun Mao · International Journal of Agricultural Sustainability · China (Guangdong)
A study in Guangdong Province, China, coupled a Bayesian belief network with density peaks clustering to analyze agricultural land resources. The research identified significant synergies between food production function and other functions, but also a trade-off with food cleanliness. Consequently, Guangdong agricultural land was zoned into five functional zones.

2025Zhongxue Zhou, Fangze Zhao, Bingjie Song · Ecological Indicators · China
This study proposed the concept of agricultural comprehensive ecological effects (ACEE), developed an evaluation framework, and applied it to the Xi'an metropolitan zone, China. A key finding was the observed decrease in the comprehensive ecological effects of agriculture when transitioning from grain planting to urban agriculture due to unsuitable agricultural practices in urbanizing areas. This decline occurs because modern agricultural practices in urbanizing areas are ecologically detrimental compared with natural ecosystems.

2025Yuanchao Hu, Prajal Pradhan, Haoran Zhang, Zhen Wang, Qianyuan Huang, Qiqi Jia, Xihong Lian, Chao Xu, Rui Yang, Yuxi Tian, Zhibang Xu, Limin Jiao, Jürgen P. Kropp · Resources Environment and Sustainability · China
This study constructed a new dataset of urban productive spaces for 124 large Chinese cities to assess the potential of urban agriculture. It found that approximately 30% of urban vegetable demand could be met by utilizing spaces such as rooftops and open areas. However, urban agriculture showed little potential for greenhouse gas emission mitigation, with an average intensity (0.30 kgCO2e/kg) similar to traditional agriculture (0.31 kgCO2e/kg).

2024Hao Yang, Runyan Zou, Yueming Hu, Lu Wang, Yingkai Xie, Zhengxi Tan, Zhiqiang Zhu, A‐Xing Zhu, Jianzhou Gong, Xiaoyun Mao · Land Use Policy · China
This study introduced an "element coupling-function synergy" analytical framework and constructed a causal Bayesian belief network to identify trade-offs and synergies among multiple functions of cultivated land resources in Guangdong, China. The findings revealed trade-offs between food cleanliness and food production/social security. Synergistic relationships were found among food production, social security, and ecological regulation, as well as among ecological regulation, habitat maintenance, and landscape culture. The study divided the area into eight functional zones and formulated multi-objective management plans.

2024Sudha Panda, Chandana Parida, Anisa Azharunnisa, Rakesh Ranjan Thakur · Discover Sustainability · India (Bhubaneswar)
This paper uses remote sensing data from 2011 to 2023 to examine agricultural land loss in Bhubaneswar, India, a smaller city experiencing significant agricultural decline. It compares the decrease in agricultural land with the increase in built-up areas. The study highlights that agricultural land conversion negatively impacts food security and proposes a nature-based solution to achieve urban food self-sufficiency.

2022Kinanti Safitri, Oekan S. Abdoellah, Budhi Gunawan, Parikesit Parikesit, Yusep Suparman, Akhmad Mubarak, Margareth Pardede · The Qualitative Report · Indonesia (Bandung)
This mixed-method study, involving 107 export-scale urban farmers in the Bandung metropolitan area, Indonesia, investigated their adaptation during the COVID-19 pandemic. Farmers prioritized commercial agriculture and adapted through market access, agricultural management, and financial resource strengthening. However, some adaptation methods were not environmentally friendly, as farmers increased reliance on synthetic inputs and used cold storage on open land, leading to intensive, non-environmentally friendly agricultural practices.

2015Jin Hee Kim, Jin I. Yun · Korean Journal of Agricultural and Forest Meteorology · South Korea (Seoul)
This study evaluated daily temperatures for June-September from 2041-2070 in Seoul, projected by the RCP8.5 climate scenario, to understand climate departure implications for urban agriculture. Analysis of climate extremes and their effects on hot pepper growth revealed that while mean temperatures might depart after 2040, extreme events like heat waves and tropical nights already exceed past variability. Applying scenario data to hot pepper cultivation showed that planting and harvest dates are expected to deviate, and the maximum cultivation duration has already deviated from past variability.

2014Yu Wang · · China (Xi'an City)
This study analyzed the dynamic changes in urban agricultural landscape (arable lands and garden plots) due to urbanization in Chang'an District, Xi'an City, China, using remote sensing, GIS, and FRAG-STAT techniques. Compared to 1999, arable land area decreased and aggregation declined by 2.45% in 2011, while garden plot area increased and aggregation rose by 10.44%. Improved urbanization levels decreased arable land area and increased fragmentation, but correlations with garden plot landscape indexes were insignificant.

2009Mattia Celio, Christopher A. Scott, Mark Giordano · Geographical Journal · India (Hyderabad)
A study in Hyderabad, India, examined urban water capture and its impacts on pre-existing claims, particularly agriculture. Urban water appropriation often leads to conflict with existing water uses. The findings indicate that the magnitude and direction of impacts from urban water transfer on agriculture vary spatially and temporally, depending on location-specific rainfall patterns, existing water infrastructure and institutions, and farmers' adaptive capacities, including recourse to groundwater.

2003James M. Wolf, M S van Wijk, X Cheng, Yuanhao Hu, C.A. van Diepen, A.W. Jongbloed, H van Keulen, C H Lu, R.P. Roetter · Environment and Urbanization · China (Beijing)
This paper reviews agricultural production trends in Beijing Municipality and their impact on water quality. Rapid urbanization and agricultural intensification have led to concerns regarding water resource quantity and quality. The agricultural sector, while supplying food, is a major water user and has contributed to significant water supply-demand gaps and high levels of water pollution, particularly from intensive crop, vegetable, and livestock production.
