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.

Three water balance models were used to quantify water use efficiency on 71 golf courses in the United States. The golf courses were separated into five geographic regions. The United States Golf Association (USGA), Tipping‐Bucket (TB), and Agro‐IBIS (AG) water balance models were used to estimate golf course water requirements. Actual water use was divided by the water requirement from each model to generate three water efficiency scores for each golf course (WES USGA , WES TB , and WES AG ). The mean WES USGA was 1.16, the mean WES TB was 1.25, and the mean WES AG was 1.17. Thus, golf courses in this study used between 16% and 25% more water than predicted by the three models. The coefficients of variation of WES USGA , WES TB , and WES AG were all 0.45 or higher, indicating that some golf courses used significantly more or less water than predicted by the models. Rooting depth, irrigated area, and soil texture were especially important modeling parameters for the golf course water requirement calculations. While onsite evaluation should still be carried out to verify the assumptions made by the water balance models, the models are promising tools to quickly identify golf course superintendents who are likely to be using water efficiently and those who could use less.
