Researcher Hakim Abdi. Photo: Private. With the aid of two satellites and machine learning, researcher Hakim Abdi is mapping the composition of tree species in Swedish forests down to the individual stands. Through the creation of a method capable of generating annual maps of tree diversity, his aim is to assist in forest management and decision-making regarding both climate and biodiversity strat

Photo credit: Thomas Millot, Unsplash Researchers have investigated the possibilities of independent, global monitoring of fossil fuel carbon dioxide emissions globally based on satellite observations. This would improve the quality of the monitoring compared to today, which is built on individual reporting by countries. Three researchers from our department contributed to this study. In the updat

Dr. Oskar Löfgren, who works interdisciplinary between remote sensing and botany to understand plant communities and their ecology, has been awarded for his thesis. "Plants can provide an overall picture of the habitat's characteristics that physically measured environmental variables cannot. Analyzing many species at the same time is important: each species contributes its own explanatory model f

High-yield food production is concentrated today in certain geographical areas, so-called "breadbaskets". But what will happen to these areas in a warmer climate? To secure food production during climate change, adapted strategies may be needed. If global warming continues, food producers may need to adapt to changing conditions. Researchers try to predict different scenarios with important crops

Finding your way and navigating around cities is not always easy. New digital maps that have a better overview can help you move more smoothly from point A to point B. Many of us have digital maps at our fingertips in our smartphones, but these maps are not adapted to guide us when walking or finding our way in new environments, for example, as tourists in an unfamiliar big city. Creating such map

Despite cooling, net autumn release of carbon dioxide from ecosystems have increased, according to research from an international research group. The results come from a large study of ecosystems in North America and Eurasia, which since 2004 have had a decreasing temperature trend in the autumn, despite the fact that average temperatures are rising globally.

Are weather events such as drought and agricultural productions shocks the main reason for violent conflicts, or are there other mechanisms that should be more considered? A recent study highlights the importance of including land-use dynamics and climate change for understanding linkages between meteorological droughts, agricultural impacts, migration and conflict.

A research team has created a picture of historical temperatures in the Arctic, spanning over a thousand years. A new technique and a recently published database of proxy data have been used in the research, and the results are an important contribution to understanding temperature changes now and in the future.

The summer 2022 brought extreme heatwaves in many places globally, and the debate has a included the term "killer heat". In moist areas the high temperatures will be even harder to the human body, and the rising temperatures may make certain areas very hard to live in by the end of this century. High temperatures in combination with humid air may cause extreme heat known as wet bulb temperature, o

A brand new publication on climate issues is released by ICOS. The leaflet FLUXES - the European Greenhouse Gas Bulletin, aims at highlighting climate issues to an audience of policymakers, policy advisors, and climate journalists. The very first volume of FLUXES focuses on regional and year-over-year changes in carbon sinks in Europe. A brand new publication on climate issues is released by ICOS.

SVT has interviewed Anders Lindroth about the long-term measurements of forest carbon uptake conducted by ICOS and researchers at the department outside Perstorp in northern Skåne. Previous measurements have shown that the drought in 2018 reduced carbon uptake in southern forests, while northern pine forests fared better. This year's drought is now affecting ongoing measurements, and researchers a
