Adapting peri-urban agriculture to climate change in Bulawayo, Zimbabwe: A qualitative assessment
2021Thulani Dube, Saziso Sibanda, Phibion Chiwara · Cogent Social Sciences · Zimbabwe (Bulawayo)
This study investigated farmers' perceived effects of climate change on peri-urban agriculture in Bulawayo, Zimbabwe, and their adaptation methods. Using a sample of thirty peri-urban plots, findings revealed that farmers perceived significant climatic changes negatively impacting their farming activities, including reduced precipitation, increased atmospheric temperature, and diminishing borehole yields. Adaptation methods included repeated planting, watering plants at night, renting animal space in other farms with more water sources, and purchasing supplementary feed for livestock.

2021Alba Canet-Martí, Rocío Pineda‐Martos, Ranka Junge, Katrin Bohn, Teresa A. Paço, Cecília Delgado, Gitana Alenčikienė, Siv Lene Gangenes Skar, Gösta F. M. Baganz · Water · Global
This paper examines nature-based solutions (NBS) for urban agriculture (UA) in circular cities, focusing on input/output streams. It identifies that the understanding of I/O streams for different NBS is insufficient to fully leverage their potential for strengthening circularity in UA. The study pinpoints gaps that hinder UA's development as an opportunity within the Circular City framework, emphasizing the need for a broader understanding of food-related urban streams.

2021Susana Toboso‐Chavero, Cristina Madrid‐López, Gara Villalba, Xavier Gabarrell, Arne Björn Hückstädt, Matthias Finkbeiner, Annekatrin Lehmann · The International Journal of Life Cycle Assessment · Global
A comprehensive environmental and social life cycle assessment of perlite, peat, and coir growing media, imported to Spain from Turkey, Germany, and the Philippines respectively, was conducted for urban rooftop farming. Environmentally, coir had the lowest burden, while perlite had the highest impacts due to mining and transport. Socially, peat performed best, but coir showed the worst scores in community infrastructure and human rights, and perlite performed lowest in health and safety.

2021Fatima Haque, Rafael M. Santos, Yi Wai Chiang · Environmental Science & Technology · Global
This viewpoint article proposes incorporating enhanced rock weathering (ERW) into urban farming as an additional climate stabilization measure. Urban farming utilizes extensive urban surface areas for food production and atmospheric CO2 sequestration through air-to-soil contact. Combining this with ERW offers a further opportunity for this negative emissions technology to gain greater utilization.

2021Hayley Q McGough · DigitalCommons - CalPoly (California State Polytechnic University) · Global
This paper investigates why plant façades on buildings frequently die, preventing them from fully realizing benefits like urban heat island reduction and improved air quality. Through interviews with landscape architects, it examines factors for maintaining plant façades and assesses if new approaches, such as earlier integration of landscape architects or biocurtains, can address the high mortality rates. The study highlights that these plant façades often fail, leading to waste and unfulfilled potential.

2021Yang Deng · Journal of Hazardous Materials Letters · Global
While rainwater harvesting (RWH) is considered a sustainable irrigation method for urban agriculture, contaminants in rainwater pose challenges to RWH practices due to potential threats to crop, soil, and human health. Based on literature data, principal pollutants such as particles, toxic metals like cadmium, copper, and zinc, synthetic organic chemicals like agrochemicals and polycyclic aromatic hydrocarbons, and waterborne pathogens were identified as likely exceeding irrigation quality criteria. This study identifies challenges, knowledge gaps, and research needs for RWH irrigation, offering a basis for technical strategies.

2021Fábio Suzart de Albuquerque, Heather L. Bateman, Cameron Scott Boehme, Daniel C. Allen, Luis Cayuela · Land · Global
This study investigated the effects of land-use and land-cover (LULC) types, vegetation greenness, and climate on avian seasonal variation abundance and richness in urban desert ecosystems, using avian community data collected seasonally (winter and spring) from 2001 to 2016. Generalized linear mixed models (GLMM) indicated that LULC was the most important predictor of avian abundance and richness. Avian abundance was highest in urban riparian and urban LULC types, followed by agriculture. Avian richness was highest in riparian environments (urban and desert), followed by agriculture, urban, and desert.

This study briefly evaluated the history of institutional and scientific aspects of hydrology, noting its increasing proximity to society and focus on urban areas. It revisited the concept of "ruralization of urban areas," proposed in 2000, from hydrological, philosophical, and applied practice perspectives. Ruralization actions like urban storage, rainwater harvesting, and urban agriculture were detailed, emphasizing their implementation with data from school-basins.
Climate changeUrban–rural linkageMore than the sum of the parts: System analysis of the usability of roofs in housing estates
2021Susana Toboso‐Chavero, Gara Villalba, Xavier Gabarrell, Cristina Madrid‐López · Journal of Industrial Ecology · Global
This study developed an integrated framework for designing sustainable roof mosaic scenarios, combining urban farming, solar energy, and rainwater harvesting on unused rooftops of housing estates. Applied to a 66,433 m² rooftop area, the framework involved multi-scale and multi-dimensional analysis. Five participatory-designed rooftop scenarios were found to improve residents' resource self-sufficiency, providing 42–53% of vegetable consumption, 9–35% of electricity, and 38–200% of water needs, depending on the scenario.

2021Daniel Petrovics, Mendel Giezen · Journal of Environmental Planning and Management · Global
This research analyzes contextual conditions for vertical farming (VF) in the Global North to assess its up-scaling potential for sustainability, particularly climate mitigation, using the Multi-Level Perspective. Findings indicate that singular VF interventions require integrated functions for viability, and VF offers the most climate mitigation potential when viewed through urban-level systemic food planning. The study also notes that globalized neoliberal political economy dynamics have implications for VF up-scaling policy.

2021Luuk Graamans · Architecture and the Built Environment · Global
This research investigated the potential and limitations of plant factories (vertical farming) for urban food production. The STACKED method was developed to assess plant factory performance across multiple scales, from leaf to facility to city, analyzing resource requirements including energy, electricity, water, CO2, and land area use for fresh vegetable production. The study found that while plant factories feature extensive climate control, their necessity, effectiveness, and efficiency remain questionable, and their effects on the urban energy balance were also assessed.

2021A. Varela, Alexandra Sandoval-Albán, Marcela Muñoz, Alfonso Goméz Gómez, Manuel Bogoya, Germán Combariza · Urban forestry & urban greening · Global
This study evaluated the optimal combination of three different modular extensive green roof structures and two types of local substrates (compost and soil + biochar) for Lactuca sativa L. var. crispa (lettuce) growth under tropical climate conditions, measuring physicochemical and biological properties of substrates and plant growth variables over seven weeks under rainy and dry conditions. A monolithic multilayer structure, high Mg concentrations, elevated amounts of 600 μm aggregates, and lower substrate bulk density were linked with higher L. sativa yield, but the specific substrate used was not associated with this result. Some physicochemical and microbiological properties of substrates changed by the experiment's end, with these changes dependent on climatic conditions.
