Klima og miljø
Klimautfordringene i landbrukssektoren er komplekse, og utviklingen innebærer forskning, teknologi og kunnskap. Innenfor feltet forskes det på klimaeffekter og tilpasninger i primærnæringene, lagring av karbon i jord, metanutslipp, lystgassutslipp, bedre økonomiske beregninger av kostnader ved ulike klimatiltak i jordbruket, og hvilke konsekvenser klimatiltakene kan få for matproduksjonen.

I tillegg til at maten vi produserer og spiser påvirker mengden klimagasser som slippes ut, påvirker også landbruket miljøet. Temaer her kan for eksempel være avrenning fra landbruket, kjemikaliebruk og landbrukets påvirkning på biodiversitet og landskap.

Dette er Kores temaside for forskning på klima og miljø i relasjon til landbruk. Her har vi samlet både norsk og internasjonal forskning på klima- og miljørelaterte temaer.


Towards an EU Regulatory Framework for Climate-Smart Agriculture: The Example of Soil Carbon Sequestration

| Type artikkel: Publisert studie

Kategori: Karbon og karbonlagring, Klima og miljø, Samfunnsutvikling

This article assesses current and proposed European Union (EU) climate and environmental law, and the legal instruments associated with the Common Agricultural Policy (CAP), to see whether soil carbon sequestration is sufficiently promoted as a promising example of ‘climate-smart agriculture’. The assessment shows that current and proposed policies and instruments are inadequate to stimulate large-scale adoption of soil carbon projects across Europe.

Impacts of organic matter amendments on carbon and nitrogen dynamics in grassland soils

| Type artikkel: Publisert studie

Kategori: Karbon og karbonlagring, Klima og miljø, Matjord

Organic matter amendments have been proposed as a means to enhance soil carbon (C) stocks on degraded soils. However, only few data exist on rates of soil C sequestration or the fate of added C in grassland soils, which are generally thought to have high C storage potential. We measured changes in the amount of C and nitrogen (N) in soils and in the composition of soil organic matter (SOM) following a single application of composted organic matter in two annual grasslands from different bioclimatic zones (coastal and inland valley).

When too much isn’t enough: Does current food production meet global nutritional needs?

| Type artikkel: Publisert studie

Kategori: Folkehelse, Klima og miljø

Sustainably feeding the next generation is often described as one of the most pressing “grand challenges” facing the 21st century. Generally, scholars propose addressing this problem by increasing agricultural production, investing in technology to boost yields, changing diets, or reducing food waste. In this paper, we explore whether global food production is nutritionally balanced by comparing the diet that nutritionists recommend versus global agricultural production statistics.

Faba Bean Cultivation – Revealing Novel Managing Practices for More Sustainable and Competitive European Cropping Systems

| Type artikkel: Publisert studie

Kategori: Belgvekster, Klima og miljø, Matplanter, Produksjonsmetoder

Faba beans are highly nutritious because of their high protein content: they are a good source of mineral nutrients, vitamins, and numerous bioactive compounds. Equally important is the contribution of faba bean in maintaining the sustainability of agricultural systems, as it is highly efficient in the symbiotic fixation of atmospheric nitrogen. This article provides an overview of factors influencing faba bean yield and quality, and addresses the main biotic and abiotic constraints. It also reviews the factors relating to the availability of genetic material and the agronomic features of faba bean production that contribute to high yield and the improvement of European cropping systems.

Maten vi kaster

| Type artikkel: Rapport

Kategori: Klima og miljø, Matsvinn

Med mathåndtering i hverdagslivet som utgangspunkt finner denne rapporten fem hovedårsaker til matsvinn i norske husholdninger: (1) Forbrukerne er usikre når det gjelder egen vurdering av mattrygghet og matkvalitet, (2) Rutinisert mathåndtering fører til for få bruksanledninger for mange matprodukter, (3) Matens verdi oppfattes som lav, (4) Langtidsplanlegging reduserer fleksibiliteten i hverdagen, og (5) Forbrukerne er lite bevisste på hvor mye mat de selv kaster. Basert på disse årsakene utredes kontekstuelle tiltak innenfor to hovedområder: (1) materielle strukturer (emballasje, butikk og kjøleskap) og sosiale og (2) kulturelle strukturer (populærformidling, måltidsorganisering og utdanning).

DEMONSTRATING STRATEGIES FOR ORGANIC AND LOW-INPUT FARMING TO MITIGATE AND ADAPT TO CLIMATE CHANGE

| Type artikkel: Rapport

Kategori: Agroforestry, Agroøkologi, Klima og miljø, Økologisk landbruk

Climate change affects our entire planet, including Europe. It is a phenomenon that is closely linked to rising Greenhouse Gas (GHG) emissions and that is already having visible detrimental effects on human activities, such as farming. The climate will keep on changing and temperatures will keep on rising, which leaves us with the questions: how does climate change affect our food supply, how do food systems affect climate change, and what can we do about it?

Sustainable agriculture within the Baltic Sea Region: Do policy measures respond to policy objectives?

| Type artikkel: Rapport

Kategori: Gjødsel, Klima og miljø, Samfunnsutvikling

The Baltic Sea is dying. Oxygen-free bottom zones are increasing despite the binding targets of Nitrogen (N) and Phosphorous (P) reduction in the Baltic Sea Action Plan (BSAP). Nutrient runoff from agriculture is the most important source of this eutrophication. According to the EU, sustainable agriculture in the Baltic Sea Region (BSR) concerns several political objectives, including reducing eutrophication by nutrient abatement measures, sustain economic viability of farms and benefit society as a whole.

Spring frost risk for regional apple production under a warmer climate

| Type artikkel: Publisert studie

Kategori: Eple, Frukt, Klima og miljø

Spring frosts, as experienced in Europe in April 2016 and 2017, pose a considerable risk to agricultural production, with the potential to cause significant damages to agricultural yields. Meteorological blocking events (stable high-pressure systems) have been shown to be one of the factors that trigger cold spells in spring. While current knowledge does not allow for drawing conclusions as to any change in future frequency and duration of blocking episodes due to climate change, the combination of their stable occurrence with the biological system under a warming trend can lead to economic damage increases.

Optimising the utilisation of agricultural manure for biogas production : a model based on the county of Vestfold in Norway

| Type artikkel: Masteravhandling

Kategori: Gjødsel, Klima og miljø, Økonomi

The threat of climate-change and the harm it is doing to the Earth has been known for a long time, and the worlds countries have come together to try to limit the damages humanity is doing. The result is multiple international conventions and agreements, most recently the Paris-agreement in 2016. Norway ratified the agreement and implemented the goals in November 2016, and have since searched for solutions to reduce the overall emissions of harmful gasses to the atmosphere. One of these goals was to produce more renewable energy.

Evaluating lifetime nitrogen use efficiency of dairy cattle: A modelling approach

The increased nitrogen (N) use efficiency in cattle farming is proposed as a key action to improve N management and reduce the environmental impact of cattle farming systems. Most attention has been given to lactating cow nutrition, excluding the elements of fertility, disease, and the non-lactating animals within the herd. Therefore, the aim of the current study was to develop a herd-level simulation model incorporating these elements to assess dairy farm N use efficiency.

The hidden cost of UK food

| Type artikkel: Rapport

Kategori: Klima og miljø, Økonomi

This report finds that the food we eat costs us about twice as much as it appears in our shopping bills. For every £1 UK consumers spend on food, additional costs of around £1 are incurred. These costs are not paid by the food businesses, nor are they included within the retail price of food. Instead they are passed on to society in a range of hidden ways. In total, production-related costs account for an extra 50p for every £1 spent on food, while the costs of diet-related disease account for an
extra 37p. One surprising conclusion is that farm support payments account for only 2.5p in every hidden £1 spent on food.

Effects of extreme weather on agricultural production and environment

| Type artikkel: Forskningsprosjekt

Kategori: Klima og miljø, Matplanter

The Nordic countries developed in the early and mid 1990’s a common concept of monitoring of environmental effects of agricultural activities. The monitoring set up consists of a number of small representative agricultural dominated catchments within each country. The primary goal of the programmes are to quantify the pollutant losses to surface waters. The monitoring programmes collect data on agricultural management practices (e.g. date of soil ploughing, date of sowing and harvest and fertilizer inputs) and crop yield data down at single field level.

Controlled traffic farming effects on soil emissions of nitrous oxide and methane

| Type artikkel: Publisert studie

Kategori: Klima og miljø, Produksjonsmetoder

Soil compaction affects soil aeration and gas diffusivity, and thus has a major impact on the release of greenhouse gases (GHGs) from fertilised soils. Controlled traffic farming (CTF) systems reduce the area of compacted soil by confining all field traffic to permanent traffic lanes, and a pilot trial at one long-term CTF site provided evidence of reduced soil emissions.

Mot et bærekraftig norsk matsystem: Effekt på selvforsyningsgrad og norsk jordbruk ved redusert konsum av kjøtt

| Type artikkel: Masteravhandling

Kategori: Husdyr, Kjøtt, Klima og miljø, Matplanter, Samfunnsutvikling, Økonomi

Sentralt i økologisk økonomi (ØØ) er tanken om at jordas ressurser er begrenset og at det finnes en optimal størrelse for økonomien. På overordnet nivå handler denne oppgaven om å anerkjenne konseptuelt at det er en øvre grense for hvor mye mat vi kan produsere på jorda. Globale endringstrender som befolkningsvekst, økt velstand og ressursbruk sammen med miljøutfordringer som klimaendringer, redusert biologisk mangfold, økt press på arealressurser, vannmangel og utarming av matjord peker mot at vi kan nærme oss en situasjon med mulig global matknapphet. I et slikt perspektiv er det naturlig å øke fokuset på matsikkerhet, og se på hvordan det norske matsystemet kan bli mer bærekraftig samtidig som det forsyner oss med en større andel av den maten vi spiser.

Crop traits drive soil carbon sequestration under organic farming

1. Organic farming (OF) enhances top soil organic carbon (SOC) stocks in croplands compared with conventional farming (CF), which can contribute to sequester C. As farming system differences in the amount of C inputs to soil (e.g. fertilization and crop residues) are not enough to explain such increase, shifts in crop residue traits important for soil C losses such as litter decomposition may also play a role.

Impact of agronomy practices on the effects of reduced tillage systems on CH4 and N2O emissions from agricultural fields: A global meta-analysis

| Type artikkel: Publisert studie

Kategori: Klima og miljø

The effect of no- and reduced tillage (NT/RT) on greenhouse gas (GHG) emission was highly variable and may depend on other agronomy practices. However, how the other practices affect the effect of NT/RT on GHG emission remains elusive. Therefore, we conducted a global meta-analysis (including 49 papers with 196 comparisons) to assess the effect of five options (i.e. cropping system, crop residue management, split application of N fertilizer, irrigation, and tillage duration) on the effect of NT/RT on CH4 and N2O emissions from agricultural fields.

Mångfunktionella, lokala odlingssystem Etablering av modern agroforestry i Sverige 2012–2016

Vår vision är att lantbruket skall bidra till en hållbar värld och vara en ”plusfaktor” i den utvecklingen. Vi människor gör anspråk på en allt större del av planetens landyta och hav. Därmed påverkar vi idag alla ekosystem på jorden liksom hela planetens klimat. Därför är det lika viktigt att bidra positivt till planetens livgivande funktioner som att producera hög skörd. Till exempel behöver det landskap som ger oss vår mat också ge boplats, skydd och föda till vilda växter och djur. Dessutom behöver ett överskott av koldioxid bindas in i mark och växter för att minska växthuseffekten. Lantbruket behöver också producera sin egen energi, bygga en levande och bördig jord och recirkulera de näringsämnen som växterna behöver.
