A contrasting seasonality of wind erosivity and wind erosion between Central and Western SaheL

Wind erosion is a major phenomenon in the Sahel, and can affect soil fertility. Studies of Sahelian aeolian erosion or erosivity are scarce and have been mainly focused on the Central Sahel. Since February 2020, the number of saltating particles and the horizontal flux of aeolian sediment were monitored in Bambey (Senegal) in combination with […]

Persistence and success of the Sahel desertification narrative

When the Sahel is mentioned today, this semi-arid African region between the Sahara and Sudanian Africa is often associated with the notion of desertification. But what do the latest advances in environmental science tell us about this desertification? To what extent is the “narrative” of Sahel desertification based on scientific results, or on other mechanisms, of a more political nature?

Ecological Functioning of Temperate and tropical Soils “FEST” Team

Team news Team publications Team members The main objective of the FEST team is to better understand the interactions between biological actors and the abiotic properties of soils, and the impact of these interactions on the resulting ecosystem services. In particular, we study the influence of soil engineers (especially earthworms, termites and microbial activity) and […]

Making better use of the third dimension of agricultural land to sustainably intensify agricultural production

In this prospective article, an international consortium coordinated by researchers from the University of Copenhagen examines the prospects for using the “third dimension” of agricultural land, i.e. the possibility, without resorting to new land, of increasing the volume of soil exploited by the root system of crops, thereby increasing the resource base available for agricultural production while minimizing the undesirable externalities frequently associated with current agroecosystems.
