What Hinders and Accelerates? : A Study of Sustainable Electric Mobility Transitions in Sri Lanka / Vad hindrar och accelererar? : En studie av övergången till hållbar mobilitet i Sri Lanka

Bandaranayake, Hasini January 2024 (has links)
The transportation sector is a key carbon emitter, and e-mobility is becoming increasingly recognised around the globe to address climate change, biodiversity loss and societal challenges. In Sri Lanka, e-mobility is identified as a major alternative option that emerged while combating the economic crisis. This paper explores potential pathways to integrate e-mobility into the Colombo Metropolitan Area (CMA) through understanding 'What hinders this e-mobility transition?' and 'How to accelerate it?'. The study applied a combination of transition studies, including MLP, Path dependency and, lock-ins and transition management theories, followed by the mixed-methods approach to analysing the complexities created along the co-evolution of socio-technical systems and to suggest potential pathways. The findings show that historical influences and diverse configuration elements hinder the capabilities of emerging e-mobility novelties by locking society in a private vehicle-dominating regime. A holistic and integrated approach is necessary to overcome the identified challenges and to achieve a sustainable e-mobility transition.

L’agriculture comme projet de société : les obstacles à une transition agroécologique juste au Québec

Sylvestre, Rachel 09 1900 (has links)
Au Québec, la pandémie de la COVID-19 a entrainé de nombreux questionnements face au système alimentaire, sa durabilité et sa résilience. Cette crise sanitaire a révélé les multiples dépendances de la province, notamment aux importations et à une main- d’œuvre étrangère bon marché, tout en exacerbant les problématiques liées à la distance entre le champ et notre assiette. D’autre part, celle-ci a souligné la fragilité socio- écologique du modèle agricole en place. L’agriculture industrielle met de l’avant plusieurs pratiques aux conséquences destructrices si néfastes pour l’environnement et l’Homme. Devant de tels enjeux, des pratiques alternatives en agriculture ont émergé au Québec dans les dernières décennies, telles que des coopératives agricoles, micro-fermes, l’agriculture urbaine, etc., ainsi que le souhait d’une plus grande autonomie alimentaire pour la province. Seulement, en dépit d’une volonté de limiter l’impact environnemental de l’agriculture sur le territoire québécois, la présence de verrouillages juridico-politiques et socio-économiques limitent le développement de ces alternatives. La présente recherche a déterminé, documenté et analysé la nature de ces verrouillages freinant ou empêchant une transition agroécologique du système alimentaire du Québec. En ayant recours à une revue de la littérature, dix entretiens semi-dirigés avec des acteurs clés du secteur agricole et de l’observation sur le terrain, nous avons documenté et analysé les changements, les réalités et les besoins en agriculture en 2022-2023. Cette étude a contribué à l’évaluation des besoins en agriculture et à l’établissement de stratégies de transformation du système alimentaire du Québec, afin qu’il fasse preuve de durabilité, d’autonomie et de résilience. / In Quebec, the COVID-19 pandemic raised awareness about the food system, its sustainability, and resilience. This health crisis revealed the province's multiple dependencies, notably on imports and cheap foreign labor, while exacerbating issues linked to the distance between the field and our plates. It also highlighted the socioecological fragility of the current agricultural model. Industrial agriculture puts forward several practices with destructive consequences that are harmful to the environment and mankind. Faced with such challenges, alternative agricultural practices have emerged in Quebec in recent decades, such as agricultural cooperatives, micro-farms, urban agriculture, etc., as well as the desire for greater food autonomy for the province. However, despite the desire to limit the environmental impact of agriculture in Quebec, the development of these alternatives is hampered by legal, political, and socio-economic lock-ins. This research has determined, documented, and analyzed the nature of these locks hindering or preventing the agroecological transition of Quebec's food system. Using a literature review, ten semi-structured interviews with key actors in the agricultural sector, and field observation, we documented and analyzed the changes, realities, and needs in agriculture in 2022-2023. This study contributed to the assessment of agricultural needs and the establishment of strategies for transforming Quebec's food system so that it demonstrates sustainability, autonomy, and resilience.
