OBSERVATION OF ECOSYSTEM CHANGES FOR ACTION (OBSGESSION)

OBSGESSION的目标和主要目标是监测和预测陆地和淡水生态系统中的生物多样性变化及其直接和间接驱动因素，将最先进的多传感器地球观测(EO)数据、创新的现场(包括公民科学)数据和产品，以及考虑到不确定性的下一代生态模型整合在一起。这一目标在结合各种数据源、现代建模和不确定性估计方面远远超出了目前的最先进水平。方法原则包括牢牢把握科学和政策需要，陆地和淡水以及地球观测组织和生态系统建模学科之间的真正跨学科，以及公平和公开的科学做法，包括与科学界和民间社会分享研究成果，以研究陆地和淡水领域的生物多样性如何发生变化，以及导致有效的以科学为基础的解决方案的进程和必要的创新，以观察生态系统的变化并付诸行动。

The objective and key ambition of OBSGESSION is to monitor and predict biodiversity change and its direct and indirect drivers in terrestrial and freshwater ecosystems through the integration of state-of-the-art multi-sensor Earth Observation (EO) data, innovative in situ (including citizen science) data, and products, together with next-generation ecological models that account for uncertainty. This aim goes well beyond the current state-of-the-art in combining the various data sources, modern modelling and uncertainty estimation. The methodological principles include firm anchoring into science and policy needs, true interdisciplinarity between terrestrial and freshwater as well as EO and ecosystem modelling disciplines, and FAIR and open science practices, including sharing of research outputs with both the scientific community and the civil society, to study how biodiversity across terrestrial and freshwater domains is changing and the processes and needed innovations leading to efficient science-based solutions towards observation of ecosystem changes for action.
