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 fósforo (P) es un elemento confinado y finito en la tierra, y la perspectiva de que se limite el acceso a sus recursos explotables ya ha desencadenado conflictos geopolíticos. A diferencia de lo que ocurre con el P, en la mayoría de ecosistemas del planeta se está produciendo un rápido aumento de la disponibilidad de carbono (C) y de nitrógeno (N). El cambio inminente en la estequiometría de los elementos disponibles que en resulta no tiene ningún equivalente en la historia de la Tierra y tendrá consecuencias profundas y aún desconocidas para la vida, el sistema terrestre y la sociedad humana. Las desviaciones que se están produciendo en los balances de C:N:P en los ecosistemas por fuerza afectarán la estructura, la función y la diversidad del sistema terrestre. La crisis en el mercado del P podría presionar el sistema alimentario mundial y provocar un efecto ambiental en cadena que abarcaría desde la expansión de tierras agrícolas hasta cambios inducidos por el encarecimiento del P en la gestión de la tierra, lo que agravaría aún más el desequilibrio estequiométrico en los recursos. Sin embargo, los impactos de esta perturbación humana sin precedentes en la estequiometría elemental son todavía un misterio para la ciencia. El proyecto imbalance-P proporcionará una mejora en la comprensión y previsión cuantitativa de estos impactos que permitirán desarrollar una serie de políticas encaminadas a disminuir los riesgos y a mitigar las consecuencias de los desequilibrios estequiométricos. Se emplearán algunos de los modelos de evaluación integrada y del sistema terrestre más importantes de Europa, calibrados utilizando datos de limitación de nutrientes en el ecosistema obtenidos en experimentos de campo. El proyecto establecerá un proceso internacional de base científica en la diplomacia del P.

Soil nutrient availability has a strong influence on the fate of soil carbon (C) during microbial decomposition, contributing to Earth’s C balance. While nutrient availability itself can impact microbial physiology and C partitioning between biomass and respiration during soil organic matter decomposition, the availability of labile C inputs may mediate the response of microorganisms to nutrient additions.

Increasing temperatures can accelerate soil organic matter decomposition and release large amounts of CO₂ to the atmosphere, potentially inducing positive warming feedbacks. Alterations to the temperature sensitivity and physiological functioning of soil microorganisms may play a key role in these carbon (C) losses. [...]

The Paris Agreement is based on emission scenarios that move from a sluggish phase-out of fossil fuels to large-scale late-century negative emissions. Alternative pathways of early deployment of negative emission technologies need to be considered to ensure that climate targets are reached safely and sustainably.

No consensus has yet been reached on the major factors driving the observed increase in the seasonal amplitude of atmospheric CO₂ in the northern latitudes. In this study, we used atmospheric CO₂ records from 26 northern hemisphere stations with a temporal coverage longer than 15 years, and an atmospheric transport model prescribed with net biome productivity (NBP) from an ensemble of nine terrestrial ecosystem models, to attribute change in the seasonal amplitude of atmospheric CO₂.

Large herbivores are a major agent in ecosystems, influencing vegetation structure, and carbon and nutrient flows. During the last glacial period, a mammoth steppe ecosystem prevailed in the unglaciated northern lands, supporting a high diversity and density of megafaunal herbivores. [...]
