The numerous skyscrapers to maximize land space over the years without adequate maintenance pose as deteriorated sites. Technological advancement has then improved these sites and provided not only regenerated buildings and spaces but also solutions to food insecurity for the inhabitants through transformational strategies from the local government. These strategies have promoted urban agriculture and introduced innovative farming measures such as rooftop gardening and hydroponic farming. These measures have been geared toward attaining sustainable environmental goals for land and water optimization within limited land spaces in the inner‐city center. This study assessed the state of these measures toward attaining the environmental goals by engaging stakeholders where open‐ended interviews were used to obtain experiences. Results showed that transformational strategies have not only improved household food security and created income‐generating opportunities but also regenerated the infrastructure of the city center. However, numerous challenges are threatening the complete realization, which are soil and water flow availability to the rooftop gardens. The situation is better with hydroponics though with its own hurdles, including the need for consistent energy supplies, input costs, and technological challenges. Overall, hydroponics presents a more promising solution to attaining land and water resource use efficiency goals with proper governance and policy support.","PeriodicalId":33290,"journal":{"name":"Urban Agriculture Regional Food Systems","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136002896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Integrated use of compost and manure is essential for sustaining soil fertility and increasing crop productivity. This study was conducted to evaluate the combined effects of compost and animal manure on mungbean growth and yield. The 12 treatments consisted of control, recommended dose of nitrogen, phosphorus, and potassium (NPK), 5 ton ha −1 of compost, 10 ton ha −1 of poultry, 10 ton ha −1 of cattle, and 10 ton ha −1 of sheep manure, and six combinations of organic amendments with 50% of their applied rate alone. These treatments were laid out in a randomized complete block design with six replications. Application of cattle manure at 10 ton ha −1 significantly increased mungbean seed yield by 66% and 84% compared to the recommended rate of NPK and control treatments, respectively. Similar observations were made on stem diameter, total pod weight, and number of seeds per pod. Plants amended with compost had the highest number of ramifications and number of pods than NPK fertilized plants, which recorded (9±) ramifications and (27±) pods per plant. On average, integrated use of 5 ton ha −1 of poultry manure + 5 ton ha −1 of cattle manure had the highest soil plant analysis development values, though not significantly different from NPK fertilizers. These results suggest that application of organic amendments could be an alternative to costly and inaccessible inorganic fertilizers for improving mungbean productivity under low‐input agriculture systems.","PeriodicalId":33290,"journal":{"name":"Urban Agriculture Regional Food Systems","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135784595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their ubiquity, we know relatively little about the characteristics of UA soils, in general, and of residential food gardens specifically. We thus sampled soils from 27 residential‐scale vegetable gardens in two western Oregon cities to describe the physical, chemical, and biological characteristics of residential‐scale UA soils. We distinguished growing sites by bed type: in‐ground beds (IGs) and raised beds (RBs). We assessed the proportion of soils that fell within published recommendations for vegetable production for various soil parameters. We found residential‐scale UA soils frequently exceeded recommended ranges for many fertility parameters. We also found differences in carbon/nitrogen ratio, active carbon, and sulfur, with RBs significantly higher than IGs. The excesses likely are due to routine overapplication of compost, soil amendments, and fertilizers by growers across their intensively managed urban spaces. Such overapplication and excess is likely to be exaggerated in RBs compared with IGs.","PeriodicalId":33290,"journal":{"name":"Urban Agriculture Regional Food Systems","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80547059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such a measure would include open municipal markets (OMMs) because of their role in promoting the social nature of the agroecological transitions. In rural areas, OMMs managed by public administrations are facing a major crisis. This paper aims to decipher the claims of the actors involved in the OMM crisis and to focus on strategies that could be taken by municipalities. Semistructured questionnaires, direct observations, and participative workshops with stallholders, consumers, local producers, and the researchers of the university were used to analyze social relationships within the framework of OMMs in the Province of Girona, Catalonia. The actors revealed a lack of connection between collectives and within the same group of stallholders. The absence of shared aspirations, along with the scant interest of public bodies in investing in the markets or recognizing their economic and social role, have all contributed to the current decline in OMMs. Open municipal markets are an active asset that are at risk of being abandoned in remote rural areas. If the actors in the market could collaborate, this would help to encourage the local economy and community cohesion and to actively promote the social dimension of the agroecological transitions.","PeriodicalId":33290,"journal":{"name":"Urban Agriculture Regional Food Systems","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78160565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of the study was to determine the effect of N rates and drip irrigation regimes on water use efficiency (WUE) and N use efficiency (NUE) of apical rooted cuttings of potato (Solanum tuberosum L.) grown in a mollic Andosol. The treatments comprised four drip irrigation regimes of 50%, 75%, 85% and 100% of the crop evapotranspiration (ETC), where ETC100% was irrigated according to the soil water depletion 2 d after full irrigation and four N rates: 0 (N0), 60 (N1), 90 (N2) and 130 kg N ha−1 (N3). The results showed that potato tuber yield, WUE, and NUE were significantly (P < .001) affected by irrigation regimes, N rates, and the interaction of both factors. The highest potato tuber yield, 58.29 Mg ha−1, was obtained under ETC100% with N3, whereas the highest WUE, 17.5 kg m−3, was found under ETC50% with N3. The apical rooted cuttings of potato grown under ETC100% with N2 produced the maximum NUE, 208.30 kg kg−1. The correlation coefficient (r = 0.31; P < .01) obtained between WUE and NUE was weak. It was also observed that an increase in irrigation amount decreased WUE and increased NUE, whereas a high N dosage increased WUE and decreased NUE of potato grown in a mollic Andosol. This study suggests that if the farmers aim to maximize NUE of apical rooted cuttings in a mollic Andosol, then they will do so at the expense of potato WUE, and yield will be looked at as a secondary factor.","PeriodicalId":33290,"journal":{"name":"Urban Agriculture Regional Food Systems","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89340706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Urban food systems are a major contributor to this dangerous development (IPCC, 2018) as well as highly affected by it in a nonhomogeneous way as the food supply to distressed urban areas and vulnerable populations will suffer most from any negative impacts. As goals are set for greenhouse gas emissions, selfsufficiency in energy and adaptation to climate change, much prominence is given to urban plans for sustainable mobility and energy efficiency in the built environment. With this Special Issue, we want to draw attention to the food issue within planning and its strong implications on space, use of resources and emissions, connecting the already mainstream claims for territorialized food systems based on solidarity relationships, and shifting diets to the challenges related to climate change and ecosocial threats. At this point in time, a wider grassrootbased movement endorses an agroecological transition that brings with it values of justice, equity, and solidarity and integrates ecological principles in the design of agricultural systems.

In this study, we investigated whether amending soil with a locally made leaf‐mold compost could (a) improve soil chemical and biological properties, (b) increase survival of a microbial inoculant with plant growth promoting and disease suppressive capabilities, and (c) enhance the yield and quality of a tomato crop. Results were promising, with dramatically greater concentrations of active soil organic matter (SOM) and marketable fruit in plots receiving the amendment in both years of the study. Foliar disease severity was also lower in compost‐amended plots in the second year of the trial. Inoculating tomato (Solanum lycopersicum L.) transplants with Trichoderma harzianum T‐22 reduced deaths that are due to transplant stress in one of the cultivars evaluated, and the compost supported greater populations of this microbe in soil demonstrating that it is possible to enhance the efficacy of beneficial microbial inoculants in field settings using targeted practices. These results indicate that urban farmers can improve the productivity of their farms by amending soils with leaf mold compost, which will help ensure the long‐term sustainability of urban farming initiatives. However, all composts should be tested to ensure they do not contain toxic levels of heavy metals or pathogens, and farmers should avoid overapplication since this can reduce crop health and lead to environmental challenges.","PeriodicalId":33290,"journal":{"name":"Urban Agriculture Regional Food Systems","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74086389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The program manages approximately 80 gardens. Each garden is provided with access to land, soil testing, clean soil and compost, water, education, and guidance for gardeners, thus effectively eliminating common obstacles to successful cultivation in urban areas. We conducted a survey of gardens within the HPC program to quantify the number and size of plots within each garden and to qualitatively assess intensity of use. Internal (donation history, age, plot and garden size, and number of plots) and external factors (population density, racial diversity, income) based on the neighborhoods surrounding the gardens were evaluated to assess their potential association with use intensity. We surveyed 66 gardens containing 1,960 plots. The mean number of plots per garden was 32 ± 20.2 with each plot having a mean area of 25.6 m2. On a scale of 0 to 3, mean use intensity was 2.26 ± 0.55. Larger gardens (p < .085) and larger plots (p < .02) are used more intensively than smaller gardens and smaller plots. Gardens were well distributed across income, population density, and racial identification. Overall gardens are well‐used across the program. For this program, providing the requisite materials and information for gardens has resulted in a program that is inclusive and is likely to provide a range of benefits for participants.","PeriodicalId":33290,"journal":{"name":"Urban Agriculture Regional Food Systems","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80172606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
