Descrizione del progetto
Uno sguardo più attento alla crisi del carbonio e dell’acqua
L’aumento della CO2 atmosferica e i cambiamenti climatici accelerano i cicli idrici terrestri, innescando siccità più frequenti e gravi e riducendo l’umidità del suolo. Questa perturbazione mette a rischio la stabilità dei bilanci del carbonio terrestre, alterando le funzioni della vegetazione. Le attività umane aggravano questi effetti attraverso la deforestazione e l’uso intensivo dell’acqua. Con il sostegno del programma di azioni Marie Skłodowska-Curie, il progetto TYPIC esplorerà il modo in cui i cambiamenti socio-ambientali influenzano le dinamiche carbonio-acqua. Utilizzando le osservazioni della Terra e i big data, TYPIC mappa le variazioni globali e distingue i meccanismi sottostanti. Identificando gli hotspot, aiuta le strategie di mitigazione sul territorio e la sostenibilità delle risorse idriche. TYPIC promette di svelare le complessità associate, informando le politiche ambientali cruciali.
Obiettivo
Terrestrial carbon and water cycles are strongly coupled. Rising atmospheric CO2 and climate change have accelerated terrestrial water cycle, causing reduced soil moisture, and more frequent and severe droughts. Such environmental changes have modified vegetation functions, endangering the stability of terrestrial carbon budget. Human activities, such as deforestation and intensive water use, have further influenced carbon-water coupling by exacerbating external perturbations. A weakening of the terrestrial carbon sink induced by progressive water stress conditions could further destabilize the climate system with potential dramatic consequences for human societies.
Despite its importance, the sensitivities of terrestrial carbon-water dynamics to socio-environmental changes remain elusive. The complexity of the topic, its interdisciplinarity, together with knowledge and methodological gaps in observing, understanding, and predicting carbon-water coupling, have hampered so far substantial progresses.
TYPIC aims to respond to such emerging global challenge by addressing two key questions: How does terrestrial carbon-water coupling respond to socio-environmental changes? How have socio-environmental trade-offs and synergies influenced the trajectories of terrestrial carbon-water dynamics over the last decades?
Here, I propose to investigate the subject with a novel approach that builds on the integration of Earth observations with big-data technologies. Satellite retrievals will be used in combination with advanced statistical tools to quantify spatial and temporal variations in terrestrial carbon-water coupling at the global scale. The underlying socio-environmental mechanisms will be disentangled through causal inference methods. Hotspot areas subject to amplification or compensatory effects between environmental and human factors will be finally identified to assist the development of land-based mitigation actions and the long-term sustainability of water resources.
