Urbanization does not affect green space bird species richness in a mid-sized city
2020Dávid Korányi, Róbert Gallé, Bettina Donkó, Dan Chamberlain, Péter Batáry · Urban Ecosystems · Germany (Göttingen)
This study in Göttingen, Germany, investigated the effects of green space (GS) types and surrounding urbanization on bird communities. Bird observations were conducted using the point-count method in allotments and parks, with urbanization levels measured by the percentage of impervious surfaces. Increasing levels of urbanization around green spaces had no effect on bird species richness, functional traits, or community composition.

2020Noiry Pérez Pompa, Santa Laura Leyva Rodríguez · Sinergia Académica · Cuba
A diagnosis of farms infested by Dichrostachys cinerea (marabú) in urban and suburban agriculture was conducted at Los Téllez farm in Becerra, Las Tunas municipality, Cuba. Soil quality indicators for reddish-brown Fersialitic soils over granitoids were evaluated across four land-use systems: two infested by D. cinerea and two agricultural systems cultivated for 10 years after marabú deforestation. Results showed that D. cinerea systems exhibited the highest soil quality index, based on organic matter, bulk density, and earthworm biomass. Conversely, cultivated systems achieved the lowest accumulation of organic carbon, oligochaete density and biomass, and total porosity.

2020Jennifer Engels, Sheree J. Watson, Henrietta Dulai, Kimberly Burnett, Christopher A. Wada, ‘Ano‘ilani Aga, Nathan DeMaagd, J. J. McHugh, Barbara Sumida, Leah L. Bremer · PLoS ONE · United States (O‘ahu)
A researcher-farmer collaboration on O‘ahu's Sumida watercress farm conducted a 25-year trend analysis and a year of intensive spring water sampling. Negative correlations were found between historical crop yields and increases in the Oceanic Niño Index, temperature thresholds, and pest outbreaks. Despite urbanization, on-farm water quality was very high, and microbial analyses suggested the farm provides nutrient retention services to downstream systems. The study demonstrates that challenges facing urban agricultural systems shift over time.

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.

2019Simon Tresch, David Frey, Renée‐Claire Le Bayon, Paul Mäder, Bernhard Stehle, Andreas Fließbach, Marco Moretti · Scientific Reports · Switzerland (Zurich)
A study in 85 urban gardens across Zurich, Switzerland, investigated the impact of gardening on five soil functions and the relationship between plant (600 spp.) and soil fauna (18 earthworm spp., 39 springtail spp.). High plant diversity positively affected soil fauna and multifunctionality, but intense garden management decreased plant diversity. This indicates a trade-off where intensive gardening, while potentially beneficial for some aspects, can negatively impact overall plant diversity.

2019Emmanuel Patroba Mhache, Elna Lyamuya · Huria Journal of the Open University of Tanzania · Tanzania (Dar es Salaam)
This review paper examined the role of urban agriculture in alleviating poverty for women in the Dar es Salaam Region, Tanzania. It found that women's participation in urban agriculture contributes to food security, increases household income (average net income Tshs 58,356.2 per month), offers employment, and reduces poverty. However, numerous bottlenecks hinder women's involvement in urban agriculture, including poor markets, water shortage, land shortage, seed unavailability, lack of capital, lack of government support, crude working tools, lack of water pumping machines for irrigation, poor storage facilities, and lack of agricultural extension services.

This study focuses on the Roma Garden, one of Istanbul's last remaining urban gardens, within the context of "DIY urbanism." In Istanbul, historical gardens are threatened by municipal policies favoring urban development, leading to the formation of "DIY" urban gardens on public land since 2013. These gardens operate without legal ties to the local state, and the destruction of urban public space over the last decade is noted as having paved the way for DIY public gardens as spaces of solidarity and shared knowledge.

2019Odiney Alvarez‐Campos, Gregory K. Evanylo · Journal of Environmental Quality · Global
The impacts of exceptional quality (EQ) biosolids and inorganic fertilizer applied for rehabilitating anthropogenic soils on potential nitrogen (N) and phosphorus (P) water quality impairment risk were compared. After two years, reclamation rates of biosolids resulted in soil P saturation ratios greater than the recommended 30% but lower than the 65% limit. While nitrate N (NO3–N) posed the greatest nutrient leaching risk, lysimeter-collected mass loading of NO3–N from reclamation rates was not greater than for the inorganic fertilizer.

This study in Accra Metropolis, Ghana, compared Anopheles gambiae s.l. species composition and insecticide resistance between two vegetable-growing and two non-vegetable growing areas. All A. gambiae s.l. populations tested were resistant to five insecticides, with lower mortalities observed in vegetable-growing areas (e.g., 2.6% and 12.5% for deltamethrin) compared to non-vegetable areas (36.2% and 38.9%). Anopheles gambiae s.s. and Anopheles coluzzii were dominant in vegetable-growing areas. The findings indicate that urban agriculture contributes to the development of insecticide resistance, which needs consideration in vector control strategies.
