résumé

Remote sensing observation on ecosystems and environment can continuously provide global insights of scientific significance on the sustainability of ecosystems and the status of human environment. It is also a concrete practice to advance the capability of global comprehensive earth observation and address ecological and environmental challenges in line with the goals and visions of advancing ecological civilization and building a shared future for all life on Earth. National Remote Sensing Center of China (NRSCC) initiated Global Ecosystems and Environment Observation: Annual Report from China (GEOARC) and has been continuously releasing 29 reports and more than 100 open-access datasets in ten years from 2012 to 2021, focusing on the priorities of Sustainable Development, Climate Change, Disaster Risk Reduction and Urban Resilience, the outcomes have been accomplished through the collaboration of governmental agencies, research institutions, international organizations and the public. The primary achievements are: (1) A batch of innovative algorithm models and data products with independent intellectual property rights have been obtained based on domestic high-resolution satellite and multi-source remote sensing images for fine-scaled remote sensing monitoring of ecosystem conditions and human footprints. (2) It has significantly improved the public's scientific cognition on key topics such as food security, climate change, urban expansion, land degradation, and natural disaster risk. (3) Fine-scaled observation and assessment were carried out on key regions such as the Belt and Road , Antarctica, Africa, ASEAN and ecologically fragile areas. This is also China's substantial contribution to the international community as the co-chair of GEO (Group on Earth Observations), and provides important information reference for decision making by relevant agencies and departments. On the occasion of 10th anniversary, this paper systematically elaborated and summarized the contents and highlights of the annual reports, and put forward the prospect of GEOARC.
