Since the demand for food is rising quickly due to population growth, the main issue for any country is plant disease mechanization in agricultural science. Recent developments in deep learning techniques have found use in plant disease recognition, offering a robust tool with exceedingly precise results. Our main goal is to employ deep learning mechanisms to better understand diseases and how to identify them quickly. In this regard, we analyzed 94 publications chosen from the last 7 years (2016–2023) that show how CNN's philosophy has evolved over this period with various approaches to treating plant diseases. Furthermore, a full description of numerous crops, diseases connected to them, various datasets relating to plant diseases, existing CNN models, and customized CNN architectures is provided. The results of this state‐of‐the‐art review can be implemented to comprehend the cutting‐edge trends in the application of deep learning (CNNs) to detect plant diseases as well as pinpoint any research gaps that require the scientific community's attention.","PeriodicalId":160037,"journal":{"name":"Urban Agriculture & Regional Food Systems","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140516670","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}

Sarpong","doi":"10.1002/uar2.20052","DOIUrl":"https://doi.org/10.1002/uar2.20052","url":null,"abstract":"This study argues that urban change and urban agriculture are linked and this relationship affects urban farmers. This causes urban farmers to adapt to the urban change and, in this study, within the Greater Accra Metropolitan Area (GAMA). This is because urban agriculture serves as a source of livelihood for urban dwellers and a source of vital food ingredients which helps address food security concerns in the city. This study employs an exploratory sequential mixed method to investigate this phenomenon, which first uses a qualitative methodology and then quantitative methodology to investigate the changes that have occurred within the GAMA and how the farmers are adapting to these changes. A heterogeneous sampling aproach was used to select a total of 29 farmers from 10 farm sites for the qualitative data, while a multistage sampling approach was used to select 251 farmers from 16 farm sites for the quantitative data. The changes within the urban space realized by farmers include climate, land scarcity, increased population, and lifestyle dynamics. The population increase and lifestyle change, for instance, increased demand for vegetables and land scarcity caused farmers to move to secured lands, which led to farmers enjoying security on those lands. However, increased population, for instance, led to more unplanned settlements, which negatively resulted in polluted streams for farming. It also led to land scarcity that has resulted in the eviction of farmers from their farmlands. In adapting to some of the effects of these changes, farmers used several water sources to reduce their dependence on the polluted streams and embarked on intensification and relocated to cheap and cost‐free lands to be able to manage the land scarcity challenge. All these adaptation strategies prove farmers' resilience to the intense urban changes, which affect their farming activities. This calls for a specialized and focused support for urban agriculture by stakeholders responsible for the promotion of urban agriculture.","PeriodicalId":160037,"journal":{"name":"Urban Agriculture & Regional Food Systems","volume":"45 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139539020","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}

To bridge the gap between rural and urban agriculture, city, state, and federal agencies such as the Natural Resources Conservation Service could expand upon the soil survey programs that currently exist and are available within the WebSoilSurvey.

In this context, it would be interesting to use a natural fertilizer present in cities like the pigeon (Columba livia) guano. In this study, we tested the effects of pigeon guano on the cherry tomato plant in an urban environment. On a rooftop at Ivry‐sur‐Seine (near Paris, France), we set up 30 cultivation bags (58.9 L volume) with two cherry tomato plants in each bag. In June 2017, we added about 15 g of pigeon guano in 1.5 L of water to each of the 15 “guano” bags and 1.5 L of water to each of the 15 “control” bags. After 15 days, we observed that the tomato plants were higher and tend to have more flowers in the guano treatment than in the control group. Finally, regarding the total number of cherry tomatoes harvested (total mass and number), it was around one to two times higher in the guano treatment than in the control. However, the average mass per fruit was not affected by the treatment. Overall, we showed that pigeon guano is an efficient local fertilizer for cherry tomato plants in urban areas.","PeriodicalId":160037,"journal":{"name":"Urban Agriculture & Regional Food Systems","volume":"107 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":"130412453","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}
