Through observational fieldwork, we quantify and spatialize the street food offer of two municipalities, which we compare to food offer in outlets (shops and restaurants). We use Mexican traditional food as a proxy for a sustainable diet. Street vendors represent 55% of the food retailers present in the study area. Over half of street vendors only sell traditional food (against 45% of food outlets), but most sell food to be consumed in moderation (e.g. tacos). A weak statistical correlation suggests that street vendors and food outlets tend to cluster in mixed-use areas; as such, street vendors' role in the urban food system is mainly to provide an alternative food offer in well-served areas, rather than providing a food offer in neighbourhoods where the formal offer is scarce. We conclude that street vending is a significant element of Mexico City's urban food environment and increases the availability of traditional food, thus enhancing food sovereignty and contributing to a sustainable food system. Street vending, as an unplanned, traditional daily practice that inadvertently contributes to a sustainable food system, is an example of ‘already existing sustainabilities’, which exploration can provide crucial insights to achieve sustainability transitions.</p>","PeriodicalId":44089,"journal":{"name":"Geo-Geography and Environment","volume":"11 2","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/geo2.152","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142320599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CiteSpace software was utilized for a bibliometric study on 137 academic publications from 2018 to 2023. Various databases were employed for methodological analysis, which involved examining publications based on models, methodologies, applications and research areas. The data were manually organized in a relational framework of an SQL database. The analysis underscored China's prominence as a leader in the extensive research devoted to this field. The United States of America and the United Kingdom played pivotal roles in providing the essential data that served as the foundation for these studies. Moreover, the long short-term memory (LSTM) algorithm was the predominant computational deep learning algorithm extensively used in this specific context. The analysis highlighted significant knowledge gaps in areas such as SST forecasting, modelling, satellite remote sensing, extreme events and data reconstruction. Future scientists need to show more interest in these and related subjects, while Chinese and American scientists should prioritize paper quality over quantity. Additionally, fostering stronger collaborations between universities and institutions is vital for further advancements. Ultimately, this study offers valuable insights into hotspot research areas and development processes, establishing the foundation for research and suggesting possible avenues for future development. The results of this evaluation serve as an essential guide for researchers and modellers involved in prediction initiatives using deep learning.</p>","PeriodicalId":44089,"journal":{"name":"Geo-Geography and Environment","volume":"11 2","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/geo2.151","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142245069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Jugaad Infrastructure: Minor infrastructure and the messy aesthetics of everyday life","authors":"Ankit Kumar","doi":"10.1002/geo2.153","DOIUrl":"https://doi.org/10.1002/geo2.153","url":null,"abstract":"<p><i>Jugaad</i> is an Indian name for versatility and improvisation, a sensibility for improvisation, an ability for improvisation and an enabling of improvisation. This paper proposes the idea of Jugaad Infrastructure for versatile socio-material infrastructure arrangements that inhabit and thrive in the messy aesthetics of everyday life. It does so by extending the focus of infrastructure geographies from ‘big stuff’ to little devices such as solar lamps that gain significance when deployed in big numbers. The paper advances two ideas. First, it argues that <i>jugaad</i> circumvents the formal–informal boundary set by designers. By piercing this boundary, <i>jugaad</i> affords more fluid socio-material relationships involving infrastructures and their users. In so doing, <i>jugaad</i> affords versatility. Second, it develops the idea of Jugaad Infrastructure. Jugaad Infrastructure folds two things into it. First, infrastructures that are designed in ways that facilitate <i>jugaad</i>, albeit within firmly maintained boundaries and attempt to capitalise on people's aptitude for <i>jugaad</i> to take different forms, inhabit different spaces, enable different purposes and all this while somewhat retaining their shape. They are easy to maintain. This helps them travel to, function and stay in different places. In this way, small devices spread around in large numbers to become big infrastructure. Second, it represents the ensembles of fluid socio-material relationships and resources involving infrastructures and their users through which infrastructures are tailored to ‘better’ fit everyday lives and needs. Jugaad Infrastructure inhabits the liminal spaces of struggle between designers claiming <i>jugaad</i> as a limited practice that leads to stable innovations and users deploying unlimited jugaadas an everyday practice of socio-material flux.

Environmentalists returned to a more adversarial posture in relation to the state and its approach to constructing a post-neoliberal development model that relied on the intensification of primary commodity extraction. Their efficacy in shaping environmental policy making and implementation declined and their activities against oil and mining extraction were met by increasingly authoritarian responses by the state.

{"title":"The invisible city: The mundane biogeographies of urban microbial ecologies","authors":"Aaron Bradshaw","doi":"10.1002/geo2.148","DOIUrl":"https://doi.org/10.1002/geo2.148","url":null,"abstract":"<p>More-than-human, multispecies and animal geographic accounts of the city have tended to focus on large, charismatic and wild organisms, to the detriment of spatially invisible other-than-humans that are central to urban reproduction. At the same time, urban microbial geographies have foregrounded embodied interactions between humans and microorganisms, whether they are symbiotic or pathogenic, often marginalising the material contributions of extracorporeal microbiomes to the urban fabric. Building from these two blindspots, this article focuses on microbial ecologies that live constitutively outside of (other-than-)human bodies and which are intimately caught up in the metabolic intensities and infrastructural environments of the urban realm. There are two key aims: (1) to explore different forms of urban microbial ecologies and (2) to examine their relationships with urban infrastructures and reproduction. My disciplinary lenses are animal geography, microbe studies and urban ecology and my case studies are focused on urban water metabolism. Thus, based on empirical fieldwork on the urban River Lea in East London and supplemented by scientific literature and technical documents, I analyse three urban microbial ecologies that correspond to the urban realms’ ‘extended microbiomes’: those involved in slow sand filtration for the treatment of drinkable water, those involved in sewage treatment via the activated sludge process and those emerging and evolving in disused urban canal infrastructure. These processes spatially manage microbial growth and modulate the distribution of different forms of microbial agency with important effects for the smooth functioning of urban water metabolism. I suggest these ecologies correspond to the ‘spaces' of microbes in the city, and characterise a mundane system of repetition and regulation. However, microbes continue to assert their agency within the spaces of urban water metabolism, create their own places and worlds and highlight a more-than-human contingency and indeterminacy at the heart of urban reproduction.</p>","PeriodicalId":44089,"journal":{"name":"Geo-Geography and Environment","volume":"11 2","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/geo2.148","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142002547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study investigates into the effects of climate change on smallholder livestock farmers in northern Ethiopia's Raya Alamata district, investigating how farmers are adapting to evolving conditions. A field survey encompassing 177 households within three rural communities, coupled with statistical analysis, revealed that droughts strike once every three seasons, causing water and forage shortages, rangeland deterioration and a surge in livestock diseases and deaths. In seasons marked by dryness and heat, the incidence of livestock illness increased markedly, and daily milk yield per cow plummeted from 4 to 1.66 litres. In response, local farmers have transitioned from open grazing to stall-feeding, heavily dependent on costly market-bought feeds. Other significant adaptive measures include providing shelter, bathing livestock during heatwaves and practicing transhumance. To enhance resilience to these issues, we advocate for improved environmental conservation, better access to climate data and resources, better animal health care, and subsidized and readily available feed. Our research underscores the profound adversities confronting smallholder livestock farmers in northern Ethiopia due to climate change, implications that extend to food security and the economic equilibrium of the area and beyond.</p>","PeriodicalId":44089,"journal":{"name":"Geo-Geography and Environment","volume":"11 2","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/geo2.149","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141973668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
