Unpacking spatial tensions : An interdisciplinary analysis of large-scale solar farm effects in drylands
- 2022
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The last decades have seen rapid growth of renewable energy globally for accommodating the urgent need of mitigating climate change. Large-scale projects like solar farms are actively financed by transnational investors to get established in drylands like Sahara. The Earth-system model simulations on large-scale solar-farm scenarios show an increased regional rainfall and vegetation cover, analogue to a “green Sahara” that happened in the past. It will not only induce local climate and ecosystem changes but also prompt remote impacts globally through atmospheric teleconnections and ocean dynamics. This suggests that spatial tensions are inherent to climate change mitigation measures, where action in one place at a particular time impacts not only this place and the short time but place at distance and time in the future. Meanwhile, case studies in social sciences seem to suggest common unintended social consequences of the ongoing projects but no systematic assessment across these projects has been done. This study thus aims to pilot an interdisciplinary investigation of the multi-dimensional effects of large-scale renewable energy projects, mainly solar farms in drylands. Our literature review of the social effects across solar farms and other major types of renewable energy projects shows that, local host communities widely bear adverse social consequences from these projects despite there are benefits at regional, national, and transnational levels. Economic redistribution and social differentiation rapidly occur through land acquisition, livelihoods, compensation, and development programs, further dividing local communities and amplifying inequalities. These social effects could be further complicated by the likely local climate and ecosystem changes as shown by our Earth-system model simulations. Based on this combined analysis, we conclude that spatial tensions in the current climate change mitigation measures challenge the assumption of global common goods and the reach of global justices. We urge interdisciplinary research to combine their different expertise for developing integrated conceptual and methodological models, for better understanding the intersected effects of renewable energy projects on drylands, and for advising fair and just climate mitigation policy and measures.

- The new connectivity, through mobile phones, social media, and wireless internet, is an agent in social change in the drylands. In this chapter, we present four case studies: the introduction of mobile apps in Mongolia and Kenya, the role of mobile telephony in the Sahel, and the introduction of online learning in the Negev Desert. Each of these case studies develops an argument around the role of connectivity in ‘giving a voice’ to the people living in drylands. Indeed, as the studies show, the new technology of communication is a resource for such populations, especially when we focus on the benefits of improved communication and access to information. However, the effective use of such a resource is hampered by the lack of knowledge of dryland dynamics among the developers of the new technology and by the imposed power relations of the State. Also, the technology may follow its own pathway, being appropriated by the population in unexpected ways and creating new power relations that may also lead to conflict.

- Throughout history, urban centres have existed at the margins of drylands. Nowadays they are expanding in connection to new local, national, and global contexts. Rich research on the urbanization–migration relationship, especially in Africa and Asia, has not given much attention to dryland cities, while emerging research suggests that climate change effects entangled with conflicts in resource use are driving or displacing people to dryland cities. Drawing on livelihoods and translocal perspectives that centralize human agency in (re)producing places and shaping relations between places through migration/mobilities, this chapter explores the driving forces behind the growth of dryland cities and the contribution of rural–urban migration to this process. Our two empirical cases—Khartoum in Sudan and Inner Mongolia in China—demonstrate that dryland cities have been produced simultaneously through migrants’ bottom-up actions, changing human–environment relationships, and shifting policy. Urban growth in drylands is nurtured by resources in the rural area through the mediation of migrants, which calls for research to look beyond the urban–rural dichotomy. Despite following some general characteristics and development directions, the dynamics of dryland cities are shaped by particular environmental and geographical characteristics of the drylands, which are associated with rural migrants’ more flexible and opportunistic but less settled relationships to the cities.

- The livelihoods approach has become dominant for understanding poverty issues and advising on development policies. Spatial perspectives have been increasingly recognised to be important for understanding the increasing complexity and dynamics of livelihoods with regional development, urbanisation and close rural-urban interactions. This study further develops this perspective by highlighting the concepts of geographical context, location and urban hierarchy and adopts a multi-scalar analytical approach. The study examines the rural poor's livelihood strategies in Jilin Province of China based on two surveys conducted with about 3000 households in total and multiple logistic regression analysis. Our results demonstrate that half of the rural poor depend on incomes and livelihood strategies without labour input. From a macro-spatial view, the rural poor living in the Western and Eastern Areas, which have more challenging geographical contexts, are more dependent on subsidy income. From a micro-spatial view, rural livelihoods change, with spatial patterns depending on distance to urban areas and the type of these areas; small and medium-sized urban areas are more important for the rural poor's livelihoods. Geographical context makes these urban effects on rural livelihoods spatially more heterogeneous. Spatial understandings of livelihoods research help to better target and tailor poverty alleviation policies.

- Age-related changes in DNA methylation were observed in cross-sectional studies, but longitudinal evidence is still limited. Here, we aimed to characterize longitudinal age-related methylation patterns using 1011 blood samples collected from 385 Swedish twins (age at entry: mean 69 and standard deviation 9.7, 73 monozygotic and 96 dizygotic pairs) up to five times (mean 2.6) over 20 years (mean 8.7). We identified 1316 age-associated methylation sites (P<1.3x10(-7)) using a longitudinal epigenome-wide association study design. We measured how estimated cellular compositions changed with age and how much they confounded the age effect. We validated the results in two independent longitudinal cohorts, where 118 CpGs were replicated in Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS, 390 samples) (P<3.9x10(-5)), 594 in Lothian Birth Cohort (LBC, 3018 samples) (P<5.1x10(-5)) and 63 in both. Functional annotation of age-associated CpGs showed enrichment in CCCTC-binding factor (CTCF) and other transcription factor binding sites. We further investigated genetic influences on methylation and found no interaction between age and genetic effects in the 1316 age-associated CpGs. Moreover, in the same CpGs, methylation differences within twin pairs increased with 6.4% over 10 years, where monozygotic twins had smaller intra-pair differences than dizygotic twins. In conclusion, we show that age-related methylation changes persist in a longitudinal perspective, and are fairly stable across cohorts. The changes are under genetic influence, although this effect is independent of age. Moreover, methylation variability increase over time, especially in age-associated CpGs, indicating the increase of environmental contributions on DNA methylation with age.

- In Sweden, several trends intersect: the gig economy is growing rapidly; immigrants find it challenging to find work; and integration policies increasingly focus on the role of the first job as a benchmark for integration. This empirical study inserts an intersectional perspective into the exploration of the gig economy by examining immigrant women’s daily working experiences within a transactional gig platform, “Yummy”. This food app links home-based chefs to public consumers through online ordering systems. Through in-depth interviews with chefs, the app management team and participatory observations at firm training sessions and food festivals, we explore the complexity of gendered and racialized precarious work from inside the gig economy to consider daily gig life from a feminist economics perspective. The study shows the gig economy does provide entrepreneurial opportunities for new immigrants with these being based on gendered norms. We demonstrate how gendered narratives of idle capacities and women’s work in the home and family spheres are marketized and transformed through the platform. Our study widens the scope of understanding the gig economy by positioning gig work as part of broader social relations between a company, the workers and gender norms.

Tidskriftsartikel (refereegranskat)abstract
- Platform-based services are rapidly transforming urban work, lives and spaces around the world. The rise of platforms dependent on largely expendable labour relations, with significant migrant involvement, must be seen as connected, and as replicating larger social processes rather than merely technological changes. This perspective paper urgently calls for an intersectional perspective to better understand social-technical relations crossing the digital-urban interface of platform urbanism in contemporary European cities. Critics of platforms and gig work, to date, have mainly focused on algorithms-based social control, degraded working conditions, problematic employment relations and precariousness of gig work. The ongoing Covid-19 pandemic has both disrupted and amplified these issues, intensifying the vulnerability of gig workers. For example, in Sweden, migrant groups and gig workers were separately identified as being hardest hit by Covid, but with little attention to the interconnectivity between these categories, nor to how these groups are co-positioned vis-a-vis larger socio-economic inequalities. Thus, we argue for a deeper understanding of the social processes underlying platforms and for active investigation of how inequalities are being produced and/or maintained in/by these processes. Urban planners, designers and policy makers will need to actively address the hybrid (digital and physical) urban spaces produced in platform urbanism in order to prevent spatial and economic inequalities. We argue for a stronger recognition of interrelated and overlapping social categories such as gender and migrant status as central to the construction of mutually constitutive systems of oppression and discrimination produced in and through the platform urbanism.

Intersectional understandings of the role and meaning of platform-mediated work in the pandemic Swedish welfare state

Tidskriftsartikel (refereegranskat)abstract
- Digitally-mediated forms of services are increasingly normalized and rapidly transforming working and everyday lives creating new digital-social-spatial relations. The platform economy, in particular, offers new ways of work and new means of consumption. These changes challenge welfare states, both in the operations of institutions and to their foundational social goals and values. In Sweden, with the onset of the COVID-19 pandemic, social and labour market segregation intersected and amplified inequalities resulting in media covering and querying the nature and role of platform-mediated work within the Swedish welfare context. Located within an intersectional perspective, this study explores how media articulations of platform-mediated work shape theoretical understandings of the platform economy during the first wave of the COVID-19 pandemic in Sweden. This was conducted through an ethnographic content analysis (ECA) of Swedish-language newspapers between January and September 2020 (96 articles). We show understandings of the platform economy are active and shifting in temporal and spatial contexts. We highlight how work and working forms tie closely to ideas of equality and welfare in the Swedish context. Intersectional perspectives reveal the central role of power structures in local context – a specific time/place- and decenters normative economic perspectives of the platform economy. This study reinforces the need for more studies on the platform economy that foreground social relations to understand inequalities produced in and through social-technological activities.

Thinking through digital mediations and spatialities of platform based work : A roundtable reflection
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This paper is a unique roundtable discussion between geographers to explore, contextualizeand problematize the role of geography in the gig economy. It brings together eight researchersfrom across Europe all working with qualitative methods and studying the gig economy. Basedon reflections and commentaries regarding the spatialities and temporalities in and of the gigeconomy, we offer an innovative approach to exploring complicated factors in an emerging andrapidly growing field. We highlight the multiple layers of geography in physical and digitalspaces and the, sometimes blurry, interactions between these. We also show howtemporalities shape the geographies of the gig economy. This paper contributes to developing,deepening and advancing theoretical challenges in understanding the gig economy. It alsobrings these challenges into an accessible, yet thorough publication that can be used inteaching about the gig economy and digital geography. We provide a pedagogical tool tosupport university teachers in using this document in their courses.
