Navigating Change: Actors, Agency and Leverage in the Seafood Industry
- 2024
-
Licentiate thesis (other academic/artistic)abstract
- How to transform systems, what is the role of actors, agency and leverage and how can we stimulate transformations towards sustainability? Negative impacts on ocean health from human activities, combined with a growing understanding of the human relation with, and dependency upon, the ocean have all contributed to a rapidly growing discourse on sustainable seafood. Calls for transformations are now common, and actors in science, among policy makers and by corporations involved in seafood production and distribution actively seek to communicate that they are part of the solution to challenges facing the ocean and the planet, including through voluntary initiatives. In parallel have advances in monitoring technologies generated vast and, in some cases, real-time data sets about vessels at sea, enabling new understanding and scrutiny of such claims and activities by researchers, businesses and civil society organizations. This thesis applies process tracing and descriptive quantitative data analysis to investigate how transformation can happen, and the conditions that enable such processes. First, focus is placed on the inner mechanics and causal actions of voluntary initiatives carried out in the Barents Sea between 1998- 2019 to address responses to illegal fishing and the expansion of bottom trawling into previously unfished waters (Paper I). Second, by collecting and synthesizing new data investigating transshipment, a practice in fisheries which has been repeatedly described as problematic and opaque despite an increasing availability of data, presenting promising entry points for transformation are identified (Paper II). Combined the findings presented in this thesis illustrate a unique perspective of corporate actors engaged in fisheries and can be used by anyone who seeks to interact and engage with the seafood industry. In particular, these cases highlight that in order to change practices, it’s essential to understand actors within the system, how they relate to each other, and how to leverage those relations. While the ocean is no longer entirely "out of sight, out of mind," numerous challenges to achieve sustainable fisheries persist. This thesis, through empirical cases drawn from the seafood industry, transcends disciplinary boundaries, aiming not only to contribute to the academic discourse, but also to address the practical challenges of achieving sustainable fisheries governance in the face of complex challenges. The thesis identifies a number of potential and previously unknown leverage points for system change, while also illustrating how diversity has historically stimulated resilience that support transformative change at the international level.

Arbetsrapport Nationell Standardiseringsstrategi : Om processarbetet i projektet Nationell Standardiseringsstrategi för digital samhällsbyggnadsinformation
- 2021
-
Reports (other academic/artistic)abstract
- This report describes how the work has been conducted in the project “A National Strategy for Standardisation of Digital Information Management within the BuiltEnvironment” (further on denoted NSS). This report describes the project background, aim, objective, methodology, schedule, organisation, and identified areas and processes that have been the basis for the development of the initial three-year strategy.The NSS project is a strategic project within Smart Built Environment’s theme“Information infrastructure”.The aim of NSS project is to get an industry-wide consensus on Sweden’s priorities regarding standardization of information management about the built environment. The objective is to deliver a framework which supports further development of the strategy until 2030 and a strategic programme for the initial three-year strategy.The theme “Information structure” has formulated specific performance targets whichin turn shall contribute to achieve some short-term effects within 2021 and 2024. These short-term effects aim to, in the long run, contribute to achieve the programme's long-term objectives by 2030. The intention of the NSS project is to contribute to the programme by clearly formulating Smart Built Environment's long-term objectives by following the project's effect logic.The NSS project consists of the following four phases:1. Initiation,2. Development of a three-year strategy (2021-2023),3. Development of a framework for subsequent strategies (2024–2026, 2027– 2029), and4. Closure.Each phase consists of several sub-goals (a total of 11), which in turn consists of several activities. These have been systematically processed and handled to achieve the project's aim and objectives.To identify the areas and processes that can streamline information flows within the built environment processes, the project team has used the process map (SBUF BIM Report 2013) as a basis.The following focus areas were identified:a) Geodata and existing conditions,b) Analysis, requirements, and review,c) Delivery from design to production, andd) Transfer between production and operations.For each focus area, several problems were identified, together with potential root causes and suggested remedy actions. A total of 19 problems or shortcomings were assessed with standards within the industry, which resulted in 39 suggested remedy actions. These actions were then further developed into eight development projectscategorized into three strategic focus areas: Application Instructions, Delivery 8 ARBETSRAPPORT NATIONELL STANDARDISERINGSSTRATEGISpecifications, and Common Information Structure. As a part of the strategy, the initiation and implementation of the above-mentioned projects is proposed to 2021 – 2023.The anchoring process of the NSS project and its framework has been an important sub-goal to ensure the project success and compliance. Continuous communication and anchoring efforts have been performed as a part of the project, partly through the various groups involved in the project (steering-, reference-, and expert support group), partly through coordination and discussions with important stakeholders and relevant parallel initiatives.The framework describes how the strategic work shall be accomplished and includes principles how to follow-up and revise the strategies. It also includes the strategic roadmap, that is a plan including objectives and milestones for navigation. The roadmap is divided into three different phases which all contain a set of projects to be conducted according to the figure below.The developed strategy and its framework are recommended to be owned and maintained by the newly created organization named “Samhällsbyggandets Regelforum”.The project also recommends how to practically follow-up the work, which is based on several identified indicators. A basic condition to ensure a quality assured and efficient implementation is “a modern and digital communication platform”. The project alsoincludes a suggested technical solution.

Reports (other academic/artistic)abstract
- The aim of this report is to provide a detailed description of the eight development projects recommended for the first strategy period (2021-2023) of the project “A National Strategy for Standardisation of Digital Information Management within the Built Environment”. The report also contains a description of the vision and the objectives of the strategy. The project has been led by Pontus Bengtson, Autodesk, in collaboration with Lars Harrie, Lund University; Cristina Lázaro Morales, Plan B; Henrik Linderoth, Jönköping University; Anna Neidenström, Swedish Transport Administration; and Håkan Norberg, Plan B. The vision of the strategy is a public construction sector with a consensus on what to be prioritized regarding standardization to promote efficient information management. This will be achieved by jointly focusing on the prioritized development projects – projects that aim to create a common information structure with the greatest user benefit. There are eight projects categorized into three strategic focus areas, Application Instructions, Delivery Specifications and Common Information Structure recommended during the first strategy phase. These projects represent the main areas of action to achieve the above-mentioned vision. The eight projects are presented in the figure below.

Combined solar and membrane drying technologies for sustainable fruit preservation in low-income countries – prototype development, modelling, and testing
- 2021
-
In: Solar Energy Advances. - : Elsevier BV. - 2667-1131. ; 1
-
Journal article (peer-reviewed)abstract
- This investigation consisted of developing and evaluating solar dryers together with semi-permeable membrane pouches for drying juicy fruits in low-income tropical countries. Two design iterations were carried out including prototype modelling and testing. The latest developed solar dryers were a passive and an active solar dryer. Modelling was initially carried out mathematically using an equation solver software followed by computational fluid dynamics. Preliminary measurements were carried out on a small-scale solar dryer. Thereafter, full-scale models were developed and tested, both in laboratory and in real conditions in Mozambique. Results from modelling were validated against measurements in laboratory in Sweden and field trials in Mozambique. Prototype building and testing in Mozambique was undertaken in collaboration with local farmers and a university. Measurement results show that the dryers help to prevent microbial growth through increased temperatures. The drying flux was increased by 50% for the passive, and by 100% for the active solar dryers compared to the ambient controls that did not use a solar dryer. The total drying time was below four days for all pouches in the dryers. The active solar dryer was shown to have the shortest drying time and the highest capacity (more pouches) but also the highest costs. Mould growth and juice fermentation were observed on control pouches drying in open air. These problems were solved with the use of solar dryer technology. However, some challenges with the membrane pouches require further development including degradation of the membrane when exposed to direct sunlight.

Evolving Perspectives of Stewardship in the Seafood Industry
- 2021
-
In: Frontiers in Marine Science. - : Frontiers Media SA. - 2296-7745. ; 8
-
Journal article (peer-reviewed)abstract
- Humanity has never benefited more from the ocean as a source of food, livelihoods, and well-being, yet on a global scale this has been accompanied by trajectories of degradation and persistent inequity. Awareness of this has spurred policymakers to develop an expanding network of ocean governance instruments, catalyzed civil society pressure on the public and private sector, and motivated engagement by the general public as consumers and constituents. Among local communities, diverse examples of stewardship have rested on the foundation of care, knowledge and agency. But does an analog for stewardship exist in the context of globally active multinational corporations? Here, we consider the seafood industry and its efforts to navigate this new reality through private governance. We examine paradigmatic events in the history of the sustainable seafood movement, from seafood boycotts in the 1970s through to the emergence of certification measures, benchmarks, and diverse voluntary environmental programs. We note four dimensions of stewardship in which efforts by actors within the seafood industry have aligned with theoretical concepts of stewardship, which we describe as (1) moving beyond compliance, (2) taking a systems perspective, (3) living with uncertainty, and (4) understanding humans as embedded elements of the biosphere. In conclusion, we identify emerging stewardship challenges for the seafood industry and suggest the urgent need to embrace a broader notion of ocean stewardship that extends beyond seafood.
