  • How the World’s Energy Problem Has Been Hidden 4 maj, 2021
    We now live in a strange world filled with half-truths, not too different from the world of the 1930s. US newspapers leave out the many stories that could be written about rising food insecurity around the world, and even in the US. We see more reports of conflicts among countries and increasing gaps between the […]
  • January Non-OPEC Oil Production Climbs Again 8 maj, 2021
    A guest post by Ovi at peakoilbarrel Below are a number of oil (C + C ) production charts for Non-OPEC countries created from data provided by the EIAʼs International Energy Statistics and updated to January 2021. Information from other sources such as OPEC, the STEO and country specific sites such as Russia, Norway and China is […]

Klimatförändringen har nog redan påverkat livsmedelsproduktionen.

Print Friendly, PDF & Email

Vi kommer ihåg sommaren 2018 och hur det varma och torra vädret fick konsekvenser med nödslakt och minskad mängd foder och lägre skördar. Vi kunde fortsätta konsumera till lite högre priser, men om det blir ett återkommande fenomen så kan även vi få svårt med försörjningen av livsmedel. Då detta är inte bara är ett lokalt problem utan vi kan se detta hända globalt också.
Denna video går in på detta, mer finns i rapporten längst ner.

Från sammanfattningen.

Abstract
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. We find that the impact of global climate change on yields of different crops from climate trends ranged from -13.4% (oil palm) to 3.5% (soybean). Our results show that impacts are mostly negative in Europe, Southern Africa and Australia but generally positive in Latin America. Impacts in Asia and Northern and Central America are mixed. This has likely led to ~1% average reduction (-3.5 X 1013 kcal/year) in consumable food calories in these ten crops. In nearly half of food insecure countries, estimated caloric availability decreased. Our results suggest that climate change has already affected global food production.
