Descripción del proyecto
Gestión de las pruebas técnicas y sobre el terreno para luchar contra la desertización
La evaluación del daño medioambiental que provoca el cambio climático depende de varios factores que se superponen en una escala variable. Las pruebas de los estudios de campo geológicos y de los sensores de observación de la Tierra son cruciales para comprender cómo los ecosistemas soportan los cambios y la pérdida de vegetación, pero su combinación es compleja. PantEOn está trabajando en un marco multiescala que vinculará los patrones de la vegetación con los recursos hídricos y la formación de sedimentos con vistas a gestionar la desertización. El proyecto trabajará en el marco de la propuesta de las Naciones Unidas sobre la neutralidad en la degradación de las tierras y se centrará en los ecosistemas mediterráneos.
Objetivo
Combating the effects of climate change (CC) is one of the top priorities of EU policy. In order for CC mitigation & adaptation measures to be successful, they must be based on sufficient knowledge about ecosystems & how they respond to change, which is complex & not linear. The identification of spatio-temporal patterns & their relationship with the underlying ecosystem processes is one of the ongoing scientific challenges in which scale-dependency constitutes one of the principal pitfalls. Passive or active Earth Observation (EO) sensors offer a vital toolset to address this issue, by providing long archives at a variety of spectral & spatial resolutions, from the global (e.g. AVHRR), & the regional (e.g. Landsat) to the local, very high-resolutions (e.g. WorldView, Orthophotos, drones).
The objective of PantEOn is to obtain empirical evidence about the long-term evolution & regime-shifts due to Climate Change of the functional & structural properties of Mediterranean ecosystems. This evidence is crucial for the identification of ecosystem resilience thresholds & the development of land degradation indicators. A multi-scale methodological framework will be developed in order to bridge the existing eco-hydro-geomorphological process-based knowledge of the Fellow, gained from 16 years of field experimentation & monitoring, with the advanced EO experience of the Hosts, to investigate & identify the spatio-temporal pattern/process relationships. The key for the proposed approach is to relate spatio-temporal patterns of vegetation with connectivity of soil surface components with respect to overland flow of water & sediments. The concluding objective of PantEOn is to provide an advancement in the design of operational indicators for the assessment & monitoring of land degradation, within the Land Degradation Neutrality framework suggested by the UN, in order to achieve the target of the Sustainable Development Goals to combat desertification by the 2030.
