FATI (‘Free-Air Temperature Increase’, UAntwerp, PLECO)
The Antwerp FATI is a facility to experimentally simulate the impact on ecosystems of future precipitation regimes, climate-warming and especially climate extremes such as intense droughts and heat waves (e.g. temperatures up to 10 °C above ambient). By using infrared heaters and automated rainout shelters in combination with programmable irrigation, the system can simulate such extreme events in the open air, in twelve 7 m² plots, under natural light and wind. Each plot can contain one large mesocosm unit, or many smaller ones in separate containers (in total > 300). This approach allows for studies with (i) many levels per experimental factor and many replicates, (ii) multiple interacting factors, (iii) multiple biodiversity levels. Measurements include micro-climate (air temperature, relative humidity, incoming and outgoing radiation, etc.), canopy temperature with infrared thermometry, soil water content, as well as a range of possible manual measurements with available ecophysiological instruments (e.g. photosynthesis, stomatal functioning, leaf pigments). Collaborating labs nearby on soil microbiology, plant biochemistry and molecular biology, and ecosystem biogeochemistry.
Example Projects at This Facility
Regime Shift
Shifting rainfall regimes: a multi-scale analysis of ecosystem response
This multi- and interdisciplinary project focused on the impact of more persistent rainfall regimes, a new fingerprint of climate change where both dry periods and wet periods get progressively longer. Researchers specializing in plant ecology, microbiology, soil structure, and genomics combined forces to study the responses of temperate grasslands, and how agricultural management might adapt to mitigate the consequences.
Horizon Europe project IRISCC
The international IRISCC project intends to enhance societal resilience to climate change driven risks across a wide variety of sectors. UAntwerp focuses in particular on agroecological approaches to protect crops and grasslands against climate extremes such as heatwaves and drought. IRISCC provides funding for transnational access to research facilities through a series of calls. Four incoming researchers will carry out projects at the Antwerp FATI and Mesoscale Ecotron, starting from 2026.
Horizon Europe MSCA
In the Horizon Europe Marie Skłodowska-Curie Action ‘The role of arbuscular mycorrhizal fungi (AMF) in agricultural grasslands exposed to increasingly persistent weather patterns’, dr. Naheeda Begum studies how plant community composition and soil inoculation with beneficial fungi could safeguard yield quantity and quality for farming business in the more variable and less predictable climate that lies ahead.
