OBSERVATION OF ECOSYSTEM CHANGES FOR ACTION (OBSGESSION)

OBSGESSION的目标和主要目标是通过整合最先进的多传感器地球观测（EO）数据，创新的原位（包括公民科学）数据和产品，以及考虑不确定性的下一代生态模型，监测和预测陆地和淡水生态系统的生物多样性变化及其直接和间接驱动因素。这一目标远远超出了目前最先进的结合各种数据来源，现代建模和不确定性估计。方法学原则包括：牢固地扎根于科学和政策需求，陆地和淡水之间以及生态系统和生态系统建模学科之间真正的跨学科性，以及公平研究和开放科学做法，包括与科学界和民间社会分享研究成果，研究陆地和淡水领域的生物多样性是如何变化的，以及导致有效科学的过程和所需的创新-基于生态系统变化观测的解决方案，以供采取行动。

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.
