Previous Common Era (i.e., the past 2000 years) climate reconstructions from Fennoscandia have focused on northern and central areas, with scarce data from the southern areas. Using varved sediments from Lake Sagtjernet in southeastern Norway, we developed a hydrogen isotope record from sedimentary leaf waxes (n-alkanes) as a proxy for hydrogen isotopes in precipitation, which we interpret as an indicator of temperature variability over the past 2000 years. The climate reconstruction provides high, decadal resolution for the period 360–770 CE, allowing critical evaluation during the Dark Ages Cold Period (around 300–800 CE) and a cooling during the 6th century, previously suggested as the coldest period of the Common Era. Our results reveal that the most rapid drop in temperature occurred from 536 to 545 CE (+74/-90 years), corresponding in time to the 536 and 540 CE volcanic eruptions. We also document an inferred cold interval that persisted from around 650 to 710 CE (+72/-90 years). While past studies have suggested prolonged cooling during the Dark Ages Cold Period, our findings show that, on average, the climate during 360–770 CE was similar to the Common Era average in the Lake Sagtjernet record. To explore socio-environmental interactions throughout the past 2000 years, we present a pollen-based environmental reconstruction and integrate it with archaeological evidence from around Lake Sagtjernet. These analyses reveal significant societal activities such as land clearing, cereal cultivation, and large-scale iron production, which drastically altered the landscape in the Viking Age (around 800–1050 CE) and the first half of the Norwegian Middle Ages (around 1050–1350 CE). Modern cultivation practices following the Black Death (1349–1350 CE) were first established around 1470 CE and increased continuously until around 1940 CE. Intensification of societal activities through the past millennium, including iron production and modern cultivation, occurred during both warmer (Medieval Climate Anomaly; 950–1250 CE) and colder (Little Ice Age; 1450–1850 CE) periods.

This thesis aims to document, discuss, and get a deeper understanding of how heritage values and natural resources in the summer farming landscape interact and can be maintained for the future. The integrated relationship between food production, landscape, biodiversity, and traditional ecological knowledge has been the focus. Through a mixed method approach and by using qualitative and quantitative data in eight papers (Paper I-VIII), the study contributes to a collection of topics essential for a more integrated understanding of the traditional land use system and products and services provided to society. NO: Hovedformålet med denne avhandlingen har vært å dokumentere, diskutere, og øke forståelsen for samspillet mellom kulturarven og naturressursene i det norske seterlandskapet, og hvordan de kan ivaretas for framtida. Det har blitt satt et spesielt fokus på sammenhengene mellom matproduksjonen, landskapet, biodiversiteten, og den tradisjonelle økologiske kunnskapen. Ved hjelp av kvalitative og kvantitative data og metoder har åtte artikler (Paper I-VIII) gitt resultater som til sammen skaper en mer integrert forståelse av det norske seterlandskapet og de produkter og tjenester som seterbruket bidrar med til samfunnet.
Abstract
Urban agriculture has the potential to contribute to more sustainable cities, but its impacts are complex and varied. By implementing robust monitoring systems, cities can better understand the true effects of urban farming initiatives. This evidence can then inform smarter policies and more effective urban planning strategies.
