Sustainable growth of the Norwegian Horticulture Food System – GreenRoad GS35 (“GrøntStrategi mot 2035)

Finished Last updated: 05.08.2025
End: jun 2025
Start: jan 2021

The main aim of GreenRoad is to deliver knowledge and solutions for increased value creation and sustainability in the horticultural food system in Norway.

Total budget 21700000

The project will define and prioritize areas and regions suitable for production of selected horticultural crops, assessing environmental, climatic, topographic, economic, social, legal and political constraints and opportunities for increased horticultural production, also in new regions (WP1).

The environmental, economic and social sustainability of different strategies for increased horticultural production will be assessed, and new assessment methodologies developed (WP2).

GreenRoad will also generate new biological and technical knowledge on methods for increased, improved, sustainable production of high quality horticultural products, taking into account provision of ecosystem services (biodiversity and pollinating activities), circularity of organic resources and the use of waste heat (WP3). The project will assess sustainable value creation barriers and opportunities at all stages in the supply chain, with a focus on seasonal labour supply, retail market structure and labelling strategies, and with Finland as a contrasting case.

Business and policy measures to increase consumption of fruits and vegetables will be identified (WP4).

Partners and stakeholders will be involved throughout the project in focus groups and other forms of participatory research, and their feedback will contribute to develop innovation platforms and pathways towards GS35 (WP5).

A case study on apples binds the different WPs together with a “farm to fork” perspective. The project involves a variety of different disciplines (biology, geography, economy, sociology…) who will collaborate in different WPs. There is a strong involvement of business and national and international research partners.

Abstract

Etter flere sjokk og prisøkninger som har påvirket den globale matproduksjonen og handelen. Har matsikkerhet blitt en viktig del av et lands totale sikkerhet. Norge er i dag avhengig av å importere store mengder frukt og grønt. For å kunne øke selvforsyningsgraden er det viktig å utnytte våre biologiske ressurser på best mulig å måte, og dermed kunne øke norskandelen på frukt og grønt. Det norske markedet for frukt og grønt er preget av sterke vertikale integrasjoner som kontrollerer andre aktørers tilgang. På bakgrunn av dette er det interessant å undersøke mulighetene i andre markedssegmenter enn kjedebutikkene, nemlig de uavhengige dagligvarebutikkene. Hovedproblemstillingen for studien har vært: Hvordan øke andelen norskprodusert frukt og grønt i det norske dagligvaremarkedet? Problemstillingen besvares gjennom en kvalitativ kartleggingsstudie der datainnsamlingen består av intervjuer, observasjon og prisregistreringer. Gjennom ti intervjuer med aktører på ulike ledd i verdikjeden, har vi avdekket utfordringer, potensiale og løsninger for å kunne øke norskandelen i uavhengige dagligvarebutikker. Alle butikkeierne i det uavhengige markedet har ulike bakgrunner og strategier. Verdikjeden for de uavhengige dagligvarebutikkene består av frittstående produsenter som leverer til uavhengige grossister. De uavhengige dagligvarebutikkene kjøper varer av uavhengige grossister i et marked uten kontrakter, stordriftsfordeler og vertikal integrasjon. Resultatene viser utfordringer i alle ledd av verdikjeden. En av hovedutfordringene er det sterke samarbeidet i verdikjeden for paraplykjedene som begrenser tilbudet av frukt og grønt til uavhengige dagligvarebutikker. Frukt og grønt i det uavhengige markedet utgjør salget av frukt og grønt en betydelig del av omsetningen, i tillegg er importnivået høyere enn i kjedebutikkene. For å kunne øke norskandelen av frukt og grønt i dagligvaremarkedet er det avgjørende å finne løsninger som gir de uavhengige dagligvarebutikkene bedre tilgang til norske produkter til konkurransedyktige priser. Grossistleddet er essensielt for å bedre tilgangen. Forbedres tilgang til norske frukt og grønt til uavhengige dagligvarebutikker vil de være med å bidra til å øke andelen norskprodusert i det norske dagligvaremarkedet.

Abstract

In 2017, two multi-location apple rootstock trials were established at 16 sites in 12 European countries. The evaluations are performed by members of the EUFRIN (European Fruit Research Institute Network) Apple & Pear Variety & Rootstock Testing Working Group. Two separate trials were arranged, grouping rootstocks into dwarf and semi-dwarf rootstocks according to the expected vigour; ‘Galaval’ was used as scion cultivar. The trial of dwarf rootstocks includes ‘G.11’ and ‘G.41’ (US), ‘EM_02’, ‘EM_03’, ‘EM_04’, ‘EM_05’ and ‘EM_06’ (UK), ‘62-396-B10®‘ (Russia), ‘P 67’ (Poland), ‘PFR4’ and ‘PFR5’ (New Zealand) and ‘Cepiland-Pajam®2’ as control. The trial of semi-dwarf rootstocks includes ‘G.202’ and ‘G.935’ (US), ‘PFR1’ and ‘PFR3’ (New Zealand), ‘EM_01’ (UK) and ‘G.11’ as a control for both trials. Part of the rootstocks (from dwarf and semi-dwarf rootstock trials) was planted in replanting conditions to test their tolerance to apple replant disease. All test trees came from the same nursery, and a common standardised evaluation protocol was used. Based on preliminary results averaged across sites, dwarf rootstocks can be ranked in terms of vigour in the following order: ‘EM_04’ < ‘EM_03’, ‘EM_05’ < ‘62-396-B10®’, ‘P 67’, ‘EM_02’, ‘G.11’ < ‘G.41’, ‘Cepiland-Pajam®2’ < ‘EM_06’, ‘PFR4’ < ‘PFR5’. On average, semi-dwarf rootstocks can be ranked in terms of vigour in the following order: ‘G11’ < ‘G.935’, ‘G.202’ < ‘PFR3’, ‘EM_01’ < ‘PFR1’. The highest cumulative yield in the young orchard was registered for trees on ‘PFR5’, ‘PFR4’, ‘G.11’, ‘G.41’, ‘Cepiland-Pajam®2’ and ‘EM_02’, while the lowest production was found for trees on ‘EM_04’. In the group of semi-dwarf rootstocks, the highest yield was on ‘PFR3’, ‘G.935’ and ‘PFR1’. Rootstocks also had a significant effect on fruit weight and fruit quality parameters. Results from the young orchards revealed interactions between sites and rootstock, potentially leading to site-specific rootstock choice based on the combination of rootstock, soil conditions and climate.

Abstract

Biofertilizers, fertilizers made from organic residues, could replace some mineral fertilizers, reducing energy consumption and resource mining. The main treatment options are composting, anaerobic digestion, drying, pyrolysis and combustion, they can be used alone or in combination. The quality of biofertilizers depend both on the original residue and on the treatment, but in most cases not all the nutrients are immediately available to plants. It is difficult to predict how available the nutrients are, and when they will become available. The methods to assess and predict nutrient availability are reviewed. Furthermore, the effect of biofertilizers on the environment in the form of nutrient losses and greenhouse gas emissions are reviewed and compared to mineral fertilizers. There is a need to produce biofertilizers with better and more predictable qualities, and also to understand their effects over multiple seasons.
