    Sammanfattning : Sustainability has been at the centre of global attention for decades. One of the most challenging areas toward sustainability is the agricultural sector. Here, the commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times higher than for open land farming. LÄS MER

    Nyckelord :Forest management; Greenhouse gas fluxes; Clear-cutting; Thinning; Stump harvesting; Selective cutting; Eddy-covariance; Flux-gradient; Greenhouse gas budgets; CO2; CH4; N2O;

    Sammanfattning : Forest ecosystems cover 31% of the terrestrial land area and store large amounts of carbon in biomass and in soils. The 2015 Paris Agreement recognizes the importance of sinks and reservoirs of greenhouse gases (GHGs) in forests and the importance of enhancing them through sustainable forest management policies.

    Sammanfattning : Falsterbo Peninsula in the south-west corner of Sweden is low-lying and built up of unconsolidated sand. Vulnerability to high water levels and wave action is of concern for the 10,000 residents of the peninsula, especially in consideration of global warming as enhanced inundation and coastal erosion problems may ensue.
