    Sammanfattning : Year-round cultivation of forest seedlings under light emitting diodes (LED) is a technology receiving increased attention from nurseries in the boreal forest regions. In these areas, the climate is characterized by strong seasonal fluctuations, resulting in short vegetation periods with narrow time windows for seedling transplanting and outdoor growth. LÄS MER

    Sammanfattning : Agricultural systems for production of food, energy and materials are a major driver of climate change, due to land use and greenhouse gas (GHG) emissions along the supply chain. Crop cultivation also affects the climate by changing land surface albedo, i.e. the fraction of solar radiation reflected back from the ground. LÄS MER
