  1. 1. Näringsförluster från sju jordbruksområden nära Mälaren

    University essay from SLU/Dept. of Soil and Environment

    Author : Sally Karlsson Bondesson; [2024]
    Keywords : avrinningsområde; belastning; fosfor; kväve; S-HYPE; retention; typområden på jordbruksmark; vattenflöde; VISS; våtmark;

    Abstract : Ett av Sveriges miljömål är ”ingen övergödning” vilket innebär att gödande ämnen inte ska ha negativ inverkan på människor, biologisk mångfald eller mark-och vattenanvändning (Naturvårds-verket 2023). Näringsämnena fosfor och kväve och förlusten av dessa från framför allt jordbruksmark är en av orsakerna till övergödning i sjöar, hav och vattendrag. READ MORE

  3. 2. TRADITIONAL ECOLOGICAL KNOWLEDGE IN AGRICULTURE FOR ADAPTATION/ RESILIENCE TO CLIMATE CHANGE: HIGH MOUNTAIN ASIA

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Dulani Lavanya Samarasekara Witharana; [2023-06-22]
    Keywords : climate change adaptation; resilient agroecosystems; Hindu Kush Himalaya; indigenous knowledge; traditional farming; traditional ecological knowledge;

    Abstract : Mountain agricultural systems in the Hindu Kush Himalaya (HKH) are in a unique position to contribute to promoting nature-based solutions in adaptation and resilience to climate change since they are least impacted by the influence of commercial high-production agriculture. This study aims to explore currently available literature for evidence of Traditional Ecological Knowledge (TEK) based agriculture in the HKH region and analyse their contribution to region and location specific climate change adaptation.

    Author : Dora Mijić; [2023]
    Keywords : Biology and Life Sciences;

    Abstract : Bryophytes play a significant role in various ecological processes, including soil succession and colonization after disturbances. Although they are commonly believed to take up nutrients from soil solutions rather than the soil itself, the influence of soil on their growth and distribution is evident from previous studies.
