This paper examines the World Health Organization (WHO) within the broader context of the post-1945 liberal international order. It begins with a brief historical account of the establishment and development of WHO, emphasizing its role as a central institution for global health governance. Particular attention is given to the role of the European Union’s (EU) member states and the United States (US) in supporting the WHO through financial contributions, personnel secondments, crisis assistance and capacity-building measures. The paper then explores more recent developments, notably the US withdrawal from the WHO during the first and second Trump administrations and the termination of key US aid programs. Finally, the implications of this withdrawal are analysed, both for WHO’s operational capacity and for transatlantic relations, with consequences for challenges such as the global fight against HIV/AIDS, antimicrobial resistance, drug and vaccine development and emergency preparedness. Keywords: World Health Organization; United States; European Union; COVID-19; public health emergency; International Health Regulations

Edible coleopteran insects are an important source for sustainable protein and generating chitin as a significant waste (exuviae, cuticle residues, and frass), which can be valorized into value-added biopolymers. These side-streams can be diverted for chitin and chitosan production due to their biocompatibility and biodegradability in biomaterial applications which gained attention in recent times. Therefore, this review evaluates various types of chitin and chitosan extractions and their structural characterization suitable for industrial applications. The nutritional and bioactive functionalities of chitin as derived from coleoptera insect side-streams were critically discussed. Furthermore, it also distinguishes the presence of α-, β-, and γ-chitin polymorphic forms exhibited in the coleopterans order with recent research gaps was also discussed herein. Currently, there is no literature review that describes the roles of coleopteran side-streams derived chitin and chitosan. Hence, this review not only underscores the potential for chitin production from coleopteran side-streams but also outlines critical bottlenecks that warrant further investigation in biopolymer chemistry. Moreover, it provides comprehensive recommendations to facilitate the scale-up of chitin and chitosan derived from coleopteran side-streams as an added advantage for new business models.

Agricultural production is highly dependent upon pollinators to achieve maximum yield and increase global food security. Wild pollinators, such as bees, are declining due to a loss of habitat from agricultural intensification, and the use of domesticated honeybees to supplement pollination services is increasing. Apple is an important, pollinator dependent food crop that commonly experiences pollination and production deficits worldwide. In this thesis, I explored whether pollination and production deficits occur in Norwegian apple orchards and what factors might be driving potential deficits. To test for pollination (seed set) and production (yield) deficits I conducted a supplemental pollination experiment for three cultivars, in eighteen orchards, in two distinct growing regions in Norway, over two years. I also assessed which pollinators are present in Norwegian apple orchards and how different groups of bees and their behaviour affect pollination of apple. Lastly, I studied different management practices to increase bee diversity and pollination success, by increasing alternate floral resources and evaluating orchard design that promotes cross-pollination. Pollination and production deficits were found across all locations, with differences in pollination deficits among cultivars. I also found that a high abundance of wild bees increases seed set in apples—a key indicator of pollination success. Behaviour also varied among bee groups, for example bumblebees visited more flowers, while solitary bees were slow, but potentially more thorough, foragers, which increases pollen deposition. Wild bees visited more apple flowers than dandelion flowers (Taraxacum spp.) when orchards were left unmowed. I also found that a higher abundance of dandelions increased bee visitation to apple flowers, suggesting higher floral diversity can increase pollination success and support a greater diversity of bees. In addition, block design orchards appear to limit cross-pollination among apple cultivars, and management actions to decrease the distance among compatible apple cultivars is needed to achieve sufficient pollination. Overall, my results suggest that greater pollination and production of apples in Norway is possible, and management actions should focus on increasing wild bee abundance and diversity, increasing alternate floral resources, and optimising orchard design to facilitate cross-pollination across shorter distances. Such actions have the potential to ensure greater yields of higher quality apples for human consumption and increased economic output for farmers.
