Biochar, a black carbon created from agricultural waste or residues, is primary an agricultural tool to improve soil health via moisture and nutrient retention with the added benefit of sequestering carbon. As global actors search for carbon dioxide removal (CDR) methods, biochar is increasingly promoted especially in sub-Saharan Africa (SSA) where smallholder farmers are largely affected by clima

This thesis explores strategic sustainability communication within the energy sector, focusing on Vattenfall's practices from 2019 to 2023. It investigates how Vattenfall employs strategic aspirations, diverse sustainability communication modes (including Communication of, about, and for Sustainability), and legitimization strategies to position itself as a leader in the Net Zero transition. B

In my thesis I have researched civil society organisations’ (CSOs) participation in climate change policies in Cambodia. CSO participation in climate change policies is an under-researched topic globally, but especially in Southeast Asia. Empirical data was gathered through interviews with CSO representatives in organizations who are engaged in climate change mitigation and adaptation (CCMA). I ha

The design of the cost model is motivated by the need of the customer to optimize its energy consumption and maximize the savings. Therefore, this tool will be able to manage the data from both power (geothermal heat pumps) and heating (district heating) systems, as well as outdoor temperatures, energy demand and other inputs, and determine which one is more feasible for every hour of the year. Al

European identity is a crucial feature for supra-national institution building in times of renewed far-right nationalism and countries leaving the European Union. High- school education may help to prepare young students to become European citizens. Eurobarometer survey data suggests that European identity and education are strongly linked to each other. This statistical connection could be mere c

Power production has a vital role in the functioning of society and will have a major part in the future of environmental and economical sustainability. Therefore, efficiencies of power plants are always a subject to improvements in order to utilise resources as efficient as possible. A Combined Cycle, combining a gas turbine topping cycle and a steam turbine bottoming cycle, is a widely used conf

The importance of early adaptation to reduce the impact of recognized risks has been underlined in recent years as featured aspect of the Sustainable Development Goals and the Sendai Framework for Action. The aim of this study is to analyze the relationship between forecasted food insecurity levels and allocated funding directed at food security. The dataset was built by combining quantitative dat

This study sets out to investigate the non-diegetic music in Christopher Nolan’s Interstellar (2014) in order to highlight its implicit narrative functions and meanings. The theoretical approach consists of semiotic concepts such as ‘Cognitive denotative’ and ‘Cognitive connotative’ functions by Emilio Audissino, ‘Myth’ and ‘Anchorage’ by Barthes as well as Claudia Gorbman’s ‘Connotative Cueing’.

There is no consensus on how to define and measure green growth. Consequently, we can neither state if growth is actually green nor econometrically explore important questions such as what determines green growth. This thesis takes a three-step approach to move one step closer to a unifying longitudinal cross-country measure of green growth. It analyzes how green growth has been quantitatively mea

In this study, I demonstrate that identity-building is an important discursive strategy for President Barack Obama in the seven-year long debate surrounding the Affordable Care Act (ACA). The data for the study comes from a 6-million word corpus of speeches that were held by Obama between January 2009 and January 2016, all published by the White House. The speeches are classified according to genr

The purpose of the study is to explore the relationship between nostalgia, brand perception and brand community, aiming to provide insight in effectively revitalizing through brand extension. Further, we aim to assess whether a shift in brand perception is a prerequisite for brand revitalization. This qualitative study utilized focus groups to explore the use of nostalgia in brand extensions and i

In the Netherlands it is very common to separate household waste inside the home. In several Dutch municipalities a financial incentive system has been implemented that is intended to motivate residents to manage and separate household waste more efficiently. The system has shown to give good results when evaluated in terms of the amount of collected household waste. However, no research exists on

Despite the international norm against the recruitment and use of child soldiers, some rebel groups continue to recruit children while others do not. Why is this so? This thesis explores the relationship between the translation of child protection norms and child soldier recruitment in four countries of West Africa: Senegal, Côte d'Ivoire, Liberia, and Mali. Building on the three-dimension mod

Polysaccharides are a versatile group of biopolymers widely utilized in a range of industries, from food and medicine to construction. Engineering of the enzymes involved in the synthesis of polysaccharides could provide a way to chemically modify the composition, and therefore be used as a tool to obtain polysaccharides with new desired properties. In this thesis, the substrate binding to the don

Across the world are small local agencies connected to the United Nations. Unlike the larger bureaucratic organs that make up the UN, these smaller specialized agencies do not work to frame the founding ideals of the UN which are decided on at the highest levels within the institution, but to interpret, carry out, and monitor different mandates or programs at the local level. These agencies transl

Food security and environmental sustainability are increasingly threatened by the current degradative practices of the agri-food industry. To mitigate the adverse environmental impacts of the agri-food supply chain, the circular food economy has been proposed as a strategy to enhance biodiversity, improve access to nutritious foods and reduce the industry’s greenhouse gas emissions. However, progr
