With rare exceptions, Third World cities are systematically urbanising, polluting and destroying their vital environmental support systems. For instance, uncollected trash frequently covers open areas in cities, creating mini-utopias for rodents and mosquito-borne disease carriers. The persistent gaps in the rates of waste production and disposal are frequently startling. Urban migration, unemployment, food prices, and growing rental housing costs have emerged as major urban problems in many Ethiopian cities. The study's primary objective was to analyse the status of food security indicators experienced by urban households and their coping mechanisms for policy implications using empirical data. The study used a mixed method research strategy that combines quantitative and qualitative research methods. Focus groups, key informant interviews, and questionnaire surveys were used to collect the data. Descriptive and inferential statistics were employed to assess the data gathered. In development studies, establishing exact, accurate, trustworthy and meaningful indicators of urban food security continue to be difficult. Despite the developing world's significant incidence of food insecurity being acknowledged, the precise number of people who lack access to food and the extent to which they are impacted remain unknown. Food security measures, such as the dietary energy supply (DES), household dietary diversity score (HDDS), and reduced coping strategy index (rCSI), were used to identify households that were food insecure. The survey found that 54% of households consumed less than 2100 kcal per adult daily and experienced food insecurity. A baseline of 2100 kcal per adult equivalent per day revealed that 56.7% of families in Bahir Dar and 52.7% of households in Gondar experienced food insecurity. Less than four food groups were consumed by 64% of households, which is far below the FAO's recommendation. The findings also showed that eating fewer meals per day, choosing fewer quality foods, and limiting portion sizes at times were the most often used coping mechanisms during food shocks. The overall findings of the study highlight an urgent need for actions that might increase the food security of the urban poor, such as price stability, the building of communal housing, enabling micro-finance and providing starting money.</p>","PeriodicalId":44089,"journal":{"name":"Geo-Geography and Environment","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/geo2.122","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43734901","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}

The habitats of these least-studied species are crucial for sustaining the Himalayan ecosystem. We employed the Maximum Entropy (MaxEnt) species distribution model to predict the potential habitat suitability of snow leopards and blue sheep and extracted common overlapped niches. For this, we utilised presence location, bio-climatic and environmental variables, and correlation analysis was applied to reduce the negative impact of multicollinearity. A total of 134 presence locations of snow leopards and 64 for blue sheep were selected from the Global Biodiversity Information Facility (GBIF). The annual mean temperature (Bio1) was found to be the most useful and highly influential factor to predict the potential habitat suitability of snow leopards. Annual mean temperature, annual precipitation and isothermality were the major influencing factors for blue sheep habitat suitability. Highly influential bio-climatic, topographic and environmental variables were integrated to construct the model for predicting habitat suitability. The area under the curve (AUC) values for snow leopard (0.87) and blue sheep (0.82) showed that the models are under good representation. Of the total area investigated, 47% was suitable for the blue sheep and 38% for the snow leopards. Spatial habitat assessment revealed that nearly 11% area from the predicted suitable habitat class of both species was spatially matched (overlapped), 48.6% area was unsuitable under niche overlap and 40.5% area was spatially mismatched niche. The presence of snow leopards and blue sheep in some highly suitable areas was not observed, yet such areas have the potential to sustain these elusive species. The other geographical regions interested in exploring habitat suitability may find the methodological framework adopted in this study useful for formulating an effective conservation policy and management strategy.</p>","PeriodicalId":44089,"journal":{"name":"Geo-Geography and Environment","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/geo2.121","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43676790","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}

The case of Japanese shark fishery based in Kesennuma, Miyagi shows the full picture of the current global context behind a highly controversial commodity: shark fins. Campaigns against shark finning directed by environmental NGOs have led to shark fin being taken off the menu at some Chinese high-class hotels. The shark fishery in Kesennuma is currently working toward obtaining Marine Stewardship Council (MSC) certification to prove that their shark products are not the result of finning, with the expectation that the certification will provide a clear distinction between human moral issues and sustainable resource management issues. Drawing on this case, this paper analyses the network of cooperative stakeholders in order to re-configure a global sustainable commodity network for shark fins. It has been almost a quarter century since MSC was officially launched as an independent organisation in 1997. Initially, MSC certification was a major strength of differentiation, allowing producers of certified seafood to sell at a higher price, but the acquisition of certification by multiple fisheries targeting the same or similar species has reduced the economic benefits for individual fisheries. By analysing the shark fishery, which require resource management on the high seas, this paper provides new insights into how MSC certification can be mobilised by producers.</p>","PeriodicalId":44089,"journal":{"name":"Geo-Geography and Environment","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2023-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/geo2.117","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43420864","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}

I propose the concept of ‘liquid urbanisms’ to understand these provisional uses of urban space. Liquid urbanisms are provisional places and spaces, connected through the loose and flexible networks of people and projects, that are not immediately obvious but which solidify around a certain project or topic, then become liquid again, until another time in the future. Liquid urbanisms was a helpful concept for me in my research, but also has a wider resonance in how we think about and conceptualise provisional locations in the city. Liquid urbanisms builds on and adds to work in urban studies, focusing attention on the spatial practices of urban actors at the local scale and acknowledging the importance of the temporal in understanding space and place and acknowledging the fluidity of cities. My research conducted in 2013–17 in Dublin initially looked at so-called ‘temporary spaces’ but quickly grew to include parks, squats, art spaces, urban gardens, autonomous social centres, networking groups and direct actions. I created the conceptual framework of liquid urbanisms to be able to discuss these projects together, as empirically from my research I could see that the projects I was researching had two main shared characteristics: a looser understanding of temporality than existed in mainstream urban planning understandings of the city, and a shared network of people, places and resources, but no body of literature encompassed both of these characteristics. The focus of this article is the concept of liquid urbanisms and how the framework of liquid urbanisms can highlight the different temporalities, spatialities and networks that exist in city spaces, reminding scholars to pay attention to the diverse fluidity of cities.</p>","PeriodicalId":44089,"journal":{"name":"Geo-Geography and Environment","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/geo2.116","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48730995","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}

The study employed a mixed research methods design for data collection and analysis. These methods included focus group discussions (FGDs), key informant interviews (KIIs), and a survey of 239 cashew-farming households. The results revealed both positive and negative outcomes for farmers and their households. First, the positive outcomes included increased income, enhanced social status, improved food and nutrition, housing and education. Second, the negative outcomes included increased theft, high cost of goods and services, high cost of living, and a rise in physical health problems among farmers. The study concludes that, overall, cashew farmers and their households experienced improved livelihoods despite the negative effects arising from cashew farming.

The major land use change observed is the conversion of green spaces and wetlands into built-up areas. The well-being of residents related to green space use in the metropolis is associated with individuals' age and gender; the presence of good quality green space, its accessibility, and perceived importance; frequency of visits; and the time spent in the green space.

The Climate Action Task Force of the American Association of Geographers (AAG), for example, was set up in 2019 and seeks to transform the annual conference in light of environmental justice concerns. Mirroring shifts in geographic practice across the globe, these efforts point to a need to understand how new opportunities for knowledge production, such as online events, can operate effectively. In this paper, we offer suggestions for best practice in virtual spaces arising from our Material Life of Time conference held in March 2021, a two-day global event that ran synchronously across 15 time zones. Given concerns about lack of opportunities for informal exchanges at virtual conferences, or the ‘coffee break problem’, we designed the event to focus particularly on opportunities for conviviality. This was accomplished through a focus on three key design issues: the spatial, the temporal, and the social. We review previous work on the benefits and drawbacks of synchronous and asynchronous online conference methods and the kinds of geographic communities they might support. We then describe our design approach and reflect on its effectiveness via a variety of feedback materials. We show that our design enabled high delegate satisfaction, a sense of conviviality, and strong connections with new colleagues. However, we also discuss the problems with attendance levels and external commitments that hampered shared time together. We thus call for collective efforts to support the ‘event time’ of online meetings, rather than expectations to fit them around everyday tasks. Even so, our results suggest that synchronous online events need not result in geographical exclusions linked to time-zone differences, and we outline further recommendations for reworking the spacetimes of the conference.</p>","PeriodicalId":44089,"journal":{"name":"Geo-Geography and Environment","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2022-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7613954/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10851608","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}

A multidisciplinary examination was conducted into the archaeological, ecological, evolutionary, geographical, genomic, glacial and zoological past, plus distribution of native terrestrial vertebrates in the Patagonia of southern South America. Notable disparities exist between main Patagonia (2.5 species/10,000 km²) compared with Tierra del Fuego (1.8). In the similar-sized area of mainland Patagonia just north of the Strait of Magellan there are 12 reptiles, 7 amphibians and 34 mammals = 53 total species; Tierra del Fuego has 13. Despite being the size of Switzerland and only 3.1 km from the mainland, Tierra del Fuego has no species of snakes, salamanders, frogs or turtles, only one lizard, one toad, nine small mammals, one carnivore and one ungulate, the Guanaco. An innovative proposal is made contrary to traditional thinking: Tierra del Fuego has relatively few native-terrestrial vertebrates because they were decimated by major tephra-ash fallout (2 to &gt;15 cm) from the Holocene 7750 YBP (years before present) Hudson volcano, the biggest and most destructive eruption in Patagonia during the past 10,000 years that eradicated indigenous peoples, most terrestrial vertebrates and all Guanacos. Neither terrestrial vertebrates nor man were replenished from the adjacent mainland for 1000 years because the Strait of Magellan was a complete biogeographical barrier. Guanacos on Tierra del Fuego have lower genetic diversity compared with the mainland, suggesting it is a younger population. Empirical evidence and pivotal events of Patagonia's prehistory support one of three hypotheses: guanacos were introduced to Tierra del Fuego by early Holocene, guanaco-dependent, indigenous peoples from the mainland who repopulated Tierra del Fuego utilising the newly invented, skilfully crafted, seaworthy bark canoe (Appendix S1–Resumen en Español).</p>","PeriodicalId":44089,"journal":{"name":"Geo-Geography and Environment","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2022-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://rgs-ibg.onlinelibrary.wiley.com/doi/epdf/10.1002/geo2.110","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49046580","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}
