2021Mekonnen Amberber Degefu, Mekuria Argaw, Gudina Legese Feyisa, Sileshi Degefa · ENVIRONMENTAL SYSTEMS RESEARCH · Ethiopia
This study characterized and compared the Spatio-temporal responses of ecological land to urban landscape dynamics in Bahir Dar, Addis Ababa, Adama, and Hawassa cities in Ethiopia for the last three decades (1990–2020). Three sets of Landsat satellite images, field observations, and urban land indexes were used to produce landscape maps and geo-spatial data analysis. Results showed that in all cities, ecological land had changed intensely regarding its quantity and spatial pattern, and the substantial expansion of built-up ecosystems was manifested at the cost of ecological land.

2021Salvatore Engel‐Di Mauro, George M. Martin · · Global
This chapter examines urban cultivation across diverse global contexts, finding that global South cities often experience declining food production due to displacement by financiers and landowners. It notes that urban cultivation is frequently associated with unacknowledged pollution problems, and its overall ecological impacts are not necessarily positive. Furthermore, urban food production, with the exception of Cuba, does little to reduce social inequality and can sometimes exacerbate it.

2021Viktoria Shchurova · Current problems of architecture and urban planning · Ukraine (Kiev)
This article highlights the problems of the negative impact of the agricultural sector integrated into the central and middle zones of large cities. A critical view was formulated on the practical implementation of scientific and legislative documents, using the example of the city of Kiev, and strategies for reorganization, restrictions, or a complete ban on estate development in urban environments were analyzed. Specific plots of estate development in Kiev were identified as requiring reconstruction or complete renovation in accordance with the city's strategic development concept.

2019Alessio Russo, Giuseppe T. Cirella · Humanities and Social Sciences Communications · Global
This comment examines "edible urbanism 5.0," noting that urban and peri-urban agriculture can have negative effects on city ecosystems, which urbanists and planners have largely overlooked. It highlights the need for a concept that considers trade-offs between ecosystem services and disservices, especially given current unsustainable industrial intensive farming. Edible urbanism aims to integrate food security, resilience, and social inclusion through edible green infrastructure and modern food production.

2019Erik Engel, Karin Fiege, Anja Kühn · · Africa
The UFISAMO project analyzed urban agriculture (UA) in Maputo and Cape Town. In Maputo, UA is the main income source for about 5% of the population, though it often does not cover monthly food costs, and a major challenge is the uncontrolled application of pesticides due to mono-cropping. In Cape Town's townships, UA plays a negligible role in income and food security due to small plots, sandy soils, water stress, and weak market links.

2016Runrid Fox-Kämper · · Global
This book provides insights and examples of how urban space is negotiated, describing urban gardens as "lived places" where social relations, meanings, and a sense of place are developed. To trigger social benefits, it is essential that these sites fulfill more functions than just food growing and leisure. Horticultural practices, such as using pesticides or fertilizers, have a strong influence on the ecological impact of urban gardening; although awareness among gardeners has increased due to training programs in recent decades, this impact persists.

2016肇 石原, Hajime Ishihara · Institutional Repositories DataBase (IRDB) · Japan (Osaka)
This study analyzed changes in green space components (parks, agricultural land, forests) across Osaka Prefecture, Japan, from 1970 to 2010. While forest area decreased slightly and park area increased, the increase in park area was insufficient to offset the significant reduction in agricultural land. Consequently, the overall green space ratio in Osaka Prefecture showed a declining trend, particularly noticeable in Osaka City and its surrounding areas.
Environmental trade-offsPolicyUrban–rural linkageClimate changeGreening and “un”greening Adelaide, South Australia
2015Guy M. Robinson, Zhiling Liu · AIMS environmental science · Australia
This paper examines the contradictions between greening and "ungreening" in Adelaide, South Australia, focusing on the city's Park Lands and urban sprawl. It argues that urban sprawl, including recent development on prime farmland, has been antithetical to biodiversity maintenance and greening principles, reducing sustainability capacity. The paper identifies problems such as conflict between biodiversity and protecting residents in bushfire risk areas, stemming from a relaxed attitude towards low-density expansion.

2014Ekaete Francis Asuquo · · Nigeria (Calabar)
The impact of urban expansion on agricultural land in Calabar and its environs, Nigeria, was investigated. A survey of 150 questionnaires and comparative assessment revealed a decrease in agricultural land in the fringes as urban expansion persists and increases. Before 2013, more farmers owned larger plots, but much of this agricultural land has been converted to housing estates, roads, leisure resorts, and schools, indicating that urban expansion has negatively impacted agricultural land, reducing food productivity and leading to farmer unemployment.

2013Zakir Hussain, Markus Hanisch · Journal of Environmental Planning and Management · India
This paper describes the adaptation of agricultural management practices in the urban periphery of Hyderabad, India, due to structural changes. Based on 120 farmer interviews, the study found that increasing costs for agricultural inputs like labor and land motivated farmers to intensify water, machine, and chemical use, which created problematic environmental impacts. Farmers also adapted by resorting to part-time farming and organizing efforts to share family labor.

2012Sylvestre Dasylva · Journal of environmental science & engineering · Senegal (Dakar)
This paper discusses rainwater management in the "niayes" zone of Dakar, Senegal. This area is characterized by agricultural depressions with typically high groundwater levels, but a recent drop has turned some into runoff-gathering sites, used for urban agriculture among other services. However, two acute problems are observed: hydrological drying due to insufficient rainwater refill and urbanization of these bottom-lands. Furthermore, decreasing pluviometry exacerbates nuisances like floods and malaria.

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.
