Climate change has likely already affected global food production

| Type artikkel: Publisert studie

Kategori: Klima og miljø

Crop yields are projected to decrease under future climate conditions, and recent research suggests that yields have already been impacted. However, current impacts on a diversity of crops subnationally and implications for food security remains unclear. Here, we constructed linear regression relationships using weather and reported crop data to assess the potential impact of observed climate change on the yields of the top ten global crops–barley, cassava, maize, oil palm, rapeseed, rice, sorghum, soybean, sugarcane and wheat at ~20,000 political units.

Klimaendringenes påvirkning på landbruket i Norge innenfor ulike klimasoner

| Type artikkel: Rapport

Kategori: Klima og miljø, Samfunnsutvikling

Klimaendringer vil ha stor påvirkning på fremtidig landbruksproduksjon i Norge og tilpasning vil være nødvendig både for å utnytte muligheter og håndtere utfordringer som følger av det nye klimaet. Klimaprojeksjoner fram mot slutten av dette århundret viser at klimaet kan endres betydelig, men det er fortsatt stor usikkerhet rundt nivået på disse endringene.

Klimarisiko og norsk matproduksjon

| Type artikkel: Rapport

Kategori: Klima og miljø

Rapporten gir en overordnet oversikt over klimarisiko i matproduksjonen med utgangspunkt i tidligere utredninger av klimaendringenes konsekvenser for jordbruket. Globale klimaendringer ventes å føre til høyere gjennomsnittstemperaturer, endringer i nedbørsmengder og fordeling, stigende havnivå, økt frekvens av ekstreme værforhold, mer planteskadegjørere og husdyrsykdommer og negative effekter på fiske og akvakultur.

Strategier i ekologisk produktion i Sverige för att öka resiliens mot extrem torka

The summer year 2018 was extremely hot and dry in Sweden. Pasture crops dried down and cattle had to graze in the forest or on bushed land not cultivated for a long time. The harvest was extremely low for all crops. Swedish agriculture is adapted to weather variations but due to climate change extreme weather conditions are expected to occur more frequent, such as too much or lack of rain. We have to answer question about what knowledge and measure the farmer use to handle the drought and produce crops, milk and beef.

Impact of projected climate change on workability, attainable yield, profitability and farm mechanization in Norwegian spring cereals

| Type artikkel: Publisert studie

Kategori: Klima og miljø, Korn, Matjord

In cold-temperate climate with high soil water content in spring, the farmer often faces the choice between topsoil compaction during seedbed preparation and delayed sowing, both of which may reduce attainable cereal yield. The objective of this study was to explore whether future climate change with increasing precipitation would aggravate this dilemma.

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.

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.
