Current State of Development and Strategy Selection of Urban Agriculture in Beijing-Tianjin-Hebei Region
2014Jiang Lu · Nongye jingji yu guanli · China (Beijing)
This study analyzed the current state of urban agriculture development in the Beijing-Tianjin-Hebei region, focusing on aspects like leading industry and farmers' income. It found that while the urban agriculture layout was basically formed, significant problems exist. These include resource and environmental crises, a lack of integrated regional planning, imperfect municipal systems, and challenges in upgrading the agricultural industry.

2014Ranka Junge, Andreas Graber · Zürcher Hochschule für Angewandte Wissenschaften digital collection (Zurich University of Applied Sciences) · Global
This paper discusses the need for practical tools and a stronger scientific base for sustainable urban farming, noting that visionary schemes often lack current practical application with available technologies. It identifies requirements for urban food production, including high quality, safety, and cost-effectiveness, and suggests innovations in planting, pest control, irrigation, and integration with existing building infrastructures. Aquaponics is presented as having the potential to contribute to all these aspects.

2014Gunwon Lee, Yunnam Jeong, Byunghak Min, Seiyong Kim · Journal of the Korea Academia-Industrial cooperation Society · South Korea
This study investigated improving South Korea's Biotope Area Ratio system for urban agriculture vitalization. The research found that the existing Biotope Area Ratio indicators, which only consider soil depth and permeability, have limitations in managing plant growth for urban agriculture. Focusing on daylight conditions as a critical factor, the study concluded that the current Biotope Area Ratio indicators are insufficient for adequately addressing plant growth in urban agriculture.

2014H. C. Agada, E. A. Obienusi, Emma E. Ezenwaji · Journal of environment and earth science · Nigeria
This study evaluated urban forestry and housing patterns in Awka metropolis, Anambra State, Nigeria, over a ten-year period (2001-2010). Analysis of land use data using linear regression and correlation coefficients confirmed a significant correlation between housing patterns (urbanization) and the distribution of trees (forestry). The least square regression results indicated that the rate of forest displacement is a direct consequence of increasing structural development in the study area.

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.

2013Priyanie Amerasinghe, R. M. Bhardwaj, Christopher A. Scott, Kiran Jella · · India
This study analyzed the current status of wastewater generation, its uses, and livelihood benefits, particularly in agriculture, in India. It was based on national data and case studies from Ahmedabad, New Delhi, Hyderabad, Kanpur, and Kolkata. A lack of systematic data collection by municipalities makes it difficult to accurately assess wastewater generation or estimate the total urban area under wastewater irrigation.

2013Larissa Vásquez-Moreno, Ana Córdova y Vázquez · International Journal of Urban Sustainable Development · Mexico (San Cristobal de Las Casas)
This study developed a conceptual framework to assess urban agriculture's (UA) potential contributions to urban sustainability (US). The framework was applied to a qualitative analysis of UA practices in San Cristobal de Las Casas, Mexico. The study found a rich practice of UA in the city and that the framework was valuable for evidencing data and stimulating analysis. However, the study also discusses limitations of UA and further refinements needed for the framework to guide actions towards increasing UA's impact on urban sustainability.

2013Beaven Utete · Journal of Water Resources and Ocean Science · Zimbabwe
The ecological integrity of the peri-urban Chiraura River system in Zimbabwe was assessed through multivariate analysis of physicochemical parameters and the resident macroinvertebrate community. Monthly collections were conducted over five months from November 2011 to March 2012 at six sites, recording 1209 macroinvertebrates. Unsustainable anthropogenic activities, including industrial, domestic, and urban agricultural activities, were found to affect the water quality of the Chiraura River through run-off and increased effluent.

2013AN Asadu, EM Igbokwe, JM Chah, IA Enwelu · Journal of Agricultural Extension · Nigeria (Enugu)
This study investigated farmers' perceptions of health and environmental hazards from urban livestock keeping in Enugu Urban, Nigeria, interviewing 75 heads of households. While all respondents were aware of general health and environmental implications, only 4.0% knew livestock could cause climate change. Identified environmental issues included crop destruction (89.3%), urban filth (89.3%), and noise (88.0%), while health issues included disease spread (50.7%), accidents (46.7%), and bad smell (86.7%).

2013Wen-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.

2013Maxine J. Levin · Soil Horizons · United States
This commentary highlights a growing demand for soil information for green economy initiatives and climate change adaptation over the last 25 years. Despite this, USDA's funding and technical support for soil surveys in urban and nonfarm areas have been inconsistent and, in some places, nonexistent. The author argues for the vital role of modern soil surveys in addressing current needs.

2013Anushiya Shrestha, Rajesh Sada · · Nepal (Kathmandu)
Climate change and its impacts on peri-urban agriculture were investigated in four peri-urban villages in the Kathmandu valley, Nepal. Temperature showed an increasing trend, while rainfall was erratic with no distinct pattern. These changes primarily had negative impacts on agriculture, leading to increased crop pests and diseases and a decline in crop production.

2013CDR Aza-Gnandji, Yongxin Xu, Lincoln Raitt, Jonathan Levy · Water SA · South Africa (Cape Town)
This study explored the salinity of irrigation water from the Cape Flats aquifer in the Philippi farming area of Cape Town, South Africa, collecting water samples from boreholes and ponds in summer and winter. Concentrations of chloride, nitrate, potassium, and sodium exceeded target maximum limits set by DWAF and FAO guidelines. Groundwater and pond water were found to be brackish in most parts of the research area, with salinization primarily attributed to agricultural activities. The water is generally suitable for irrigation but requires caution for salt-sensitive vegetables.

2013Amanda Jessie Weaver · Digital Commons - DU (University of Denver) · United States (Colorado)
This project combined U.S. Agricultural Census data with a survey of local producers in Colorado's Front Range Urban Corridor to examine the competition between urban development and food production. The study found that urban development is increasingly encroaching on rich agricultural lands, which are also desirable for housing. Consequently, Colorado faces increasing competition for land, potentially driving local food prices up and displacing producers to peripheral areas or out of food production entirely.

2013Patrick F. Banga · · Zimbabwe
Unsanctioned urban agricultural activities in Emakhandeni High Density Suburb of Bulawayo, Zimbabwe, negatively impact biodiversity. Researchers interviewed 100 people and conducted field visits, finding that the majority of cultivators operate outside existing laws and guidelines. This leads to progressive land degradation, massive deforestation, soil erosion, dried wetlands, lowered water table, and compromised groundwater quality due to pesticides and inorganic fertilizers.
