Angelica a hardy biennial herb, native to Norway, Sweden, Iceland, Greenland, the Faeroes, Finland, Russia, and eastern parts of continental Europe. Two subspecies are found in the Nordic wild flora A. archangelica ssp. archangelica (mountain subspecies) and A. archangelica ssp. litoralis (lowland subspecies). It is the mountain form that traditionally has been used both wild picked as well as cultivated. All parts of the angelica plant can be used and contain essential oil that gives it a strongly aromatic fragrance and a powerful flavor, and the plant also contains larger or smaller amounts of sugar. Angelica was a commodity in Norway even before the year 1000 and is the only vegetable, of Nordic origin. It has been used both as a vegetable, a spice and a medicinal plant. Interest as well as need for locally and regionally produced products is constantly increasing, Angelica, with its multifunctionality into more uses, could be an important plant for self-sufficiency and business creation in the arctic. In a cultivation trial in Norway looking into the fertilizer effect on yield and oil content in Angelica we found that 120 kg N/Ha gave a significantly higher yield of leaves, in one year old plants, than 40 or 0 kg N, 14-ton fresh weight/Ha compared to 11 ton and 5,6 ton respectively, 80 kg N/Ha gave 13t /Ha. The same was found in three-year-old plants. For root yield we did not see any significant effect of fertilizer treatment. The yield in essential oils was unaffected by fertilizer treatments but varied between plant parts, seeds 1,1%, roots 0,5% and leaves 0,2% oil. The dominating oils in the seeds were beta-phellandrene (69%) and alpha-pinene (13%), in roots and leaves alpha-pinene (43%, 20% resp.) and Sabinene (9%, 34% resp.) were the major compounds. In these trials only one variety of Angelica has been tested. More varieties should be studied and cultivation trials in more areas performed. Also considering that, several aromatic plants produce higher level of essential oils and chemical compounds when growing under long daylight hours. Angelica has a high potential for increased use and value creation through cultivation and processing in the Arctic region.

Abstract
Carrageenophytes such as Eucheuma and Kappaphycus play a vital role in supporting coastal economies and supplying the global hydrocolloid industry, with Indonesia producing over 75% of the world’s supply. However, the unregulated use of chemical liquid fertilisers (CLF) in seaweed farming poses serious ecological and socio-economic threats. In Sikka Regency, Indonesia, CLF use contributed to a decade-long collapse in cultivation, worsened by destructive fishing practices. Although efforts to revive farming began in 2018, current monitoring data are limited and fragmented. Nutrient over-enrichment from fertilisers has been linked to harmful algal blooms, epiphyte overgrowth, and diseases like ice-ice. While countries like the Philippines have introduced standards such as the GAqP for seaweeds, Indonesia still lacks formal regulation on fertiliser use. Misleading scientific claims and social media endorsements further promote detrimental practices. This article highlights the urgent need for public awareness, science-based guidelines, and coordinated policy to safeguard sustainable seaweed aquaculture. Extension services, farmer cooperatives, and social media can raise awareness, but added resources are required for guidelines, stronger policies, and market incentives discouraging CLF use.

A survey including 3112 responses from individual end users of wood cladding, from Norway, Sweden and Germany, was conducted with questions related to their experience and preferences regarding cladding with and without coatings. Based on these results and established scientific understanding of Service Life Prediction (SLP) of wood cladding, two decision trees were provided to guide end users in selecting a suitable material to meet their expectations when planning a new cladding. This approach makes the users reflect on maintenance requirements and aesthetic changes rather than choosing a product solely based on initial aesthetic appeal.

To optimise the use of renewable materials in construction, it is essential to understand the factors influencing decisions throughout their design and service life. Life Cycle Costing (LCC) supports sustainable development by aiming to minimise long-term costs through informed planning of service life, maintenance, and replacement. Central to this is the engineering concept of limit states - Ultimate Limit States (ULS) for structural safety and Serviceability Limit States (SLS) for functionality. However, in non-loadbearing applications such as cladding, maintenance is often driven by aesthetic deterioration rather than structural concerns. These aesthetic limit states are subjective and influenced by user preferences, personality traits, and cultural background. In practice, undesired aesthetic changes are among the main reasons for cladding replacement in Europe, alongside fungal decay and modernisation. Premature replacement due to insufficient communication about weathering effects and maintenance needs remains under-addressed. By accounting for variation in user preferences, material selection can be tailored to support a longer service life. This study presents multi-country variation in climate-related perceptions of wood and user preferences for wooden cladding.

'Honeycrisp' apples are a crisp cultivar known for their unique texture and flavor. This cultivar is considered revolutionary in the world of crispy apples due to its high value and strong consumer preference. Many new cultivars have recently been developed using 'Honeycrisp' as a parent. However, growing, producing, storing, and marketing 'Honeycrisp' apples present significant challenges. A holistic approach to 'Honeycrisp' production will be discussed, covering aspects such as soil health, rootstocks, orchard management, environmental factors, physiological disorder development, storage protocols, and marketing strategies for sustainable production.
