Researcher Patrik Vestin writes in a " news and views " article in Nature that the woody surfaces of trees may take up methane on a scale of global importance. This is a missing piece in the estimation of global methane budgets, and hence in climate models. Future research should involve not just stems and trunks, but also leaves and small branches to get a fuller picture. Forests play a crucial r

Africa, despite its large area and thus large impact on the global carbon cycle, is relatively unexplored with respect to ecosystem functions and impact on climate change. Now one of few in situ studies over a long period of time, 2010-2022, shows that the Sahel area has lost a lot of its power as a carbon sink during the time period examined. Africa, despite its large area and thus large impact o

Allowing nature to cover up after human activities, known as rewilding, has several benefits. It improves the resilience of ecosystems, increases biodiversity and favours the interaction between nature and society. This is according to a new study from Lund University. Rewilding is a method that aims to re-establish animal and plant species that have disappeared from a particular area. In a new st

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 updated Paris Agreement from COP26 Climate

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

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 maps requires in-depth knowledge about map design which can be further improved by using new technology that can process large amounts of data. “We are collaborating with

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. In the recent article "Societal

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 Arctic is the area in the world that is heating up the fastest, through so-called

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

Looking at old forests, in the small areas of forest lands where they are left untouched, and looking among other things at carbon dynamics. For the team this was a unique experience, and two field assistants have now published a film showing some of the environment and work deep in the forests far from common roads. Pristine or very old forests are not very common in the managed forest areas that

In May and June 2020, more that 300 dead elephants were found in Botswana´s Okavango Delta. Initially it was suspected that poaching was the reason, but it was later shown that they were poisoned by cyanobacteria. This is an increasing environmental problem, and recent work to create a global dataset on algal blooms shows significant changes in the last twenty years. Toxic algal blooms in water, k
