ERC Synergy grant - 2013 - 610028: Quantify the responses of ecosystems and society in a world increasingly rich in N and C but limited in Phosphorus

El fòsfor (P) és un element confinat i finit a la terra, i la perspectiva que es limiti l’accés als seus recursos explotables ja ha desencadenat conflictes geopolítics. A diferència del que passa amb el P, en la majoria d’ecosistemes del planeta s’està produint un ràpid augment de la disponibilitat de carboni (C) i de nitrogen (N). El canvi imminent en l'estequiometria dels elements disponibles que en resulta no té cap equivalent en la història de la Terra i tindrà conseqüències profundes i encara desconegudes per a la vida, el sistema terrestre i la societat humana. Les desviacions que s’estan produint en els balanços de C:N:P als ecosistemes fer força afectaran l'estructura, la funció i la diversitat del sistema terrestre. La crisi en el mercat del P podria pressionar el sistema alimentari mundial i provocar un efecte ambiental en cadena, que abastaria des de l'expansió de terres agrícoles fins a canvis induïts per l’encariment del P en la gestió de la terra, la qual cosa agreujaria encara més el desequilibri estequiomètric en els recursos. No obstant això, els impactes d'aquesta pertorbació humana sense precedents en l'estequiometria elemental són encara un misteri per a la ciència. El projecte IMBALANCE-P proporcionarà una millora en la comprensió i previsió quantitativa d’aquests impactes que permetran desenvolupar una sèrie de polítiques encaminades a disminuir els riscos i a mitigar les conseqüències dels desequilibris estequiomètrics. S’empraran alguns dels models d'avaluació integrada i del sistema terrestre més importants d'Europa, calibrats utilitzant dades de limitació de nutrients en l'ecosistema obtinguts en experiments de camp. El projecte establirà un procés internacional de base científica en la diplomàcia del P.

Above- and belowground carbon (C) stores of terrestrial ecosystems are vulnerable to environmental change. Ecosystem C balances in response to environmental changes have been quantified at individual sites, but the magnitudes and directions of these responses along environmental gradients remain uncertain.

Departrment of Atmospheric and Oceanic Sciences) ; Wohlfahrt, G. (University of Innsbruck (Àustria). Institute of Ecology) ; Zeeman, M. J. (Karlsruhe Institut für Technologie (Alemanya))
Regional ecosystem productivity is highly sensitive to inter-annual climate variability, both within and outside the primary carbon uptake period. However, Earth system models lack sufficient spatial scales and ecosystem processes to resolve how these processes may change in a warming climate. [...]

This article describes how natural geothermal soil temperature gradients in Iceland have been used to study terrestrial ecosystem responses to soil warming. The experimental approach was evaluated at three study sites in southern Iceland; one grassland site that has been warm for at least 50 years (GO), and another comparable grassland site (GN) and a Sitka spruce plantation (FN) site that have both been warmed since an earthquake took place in 2008.
