We present a globally applicable framework to identify drought thresholds for vegetation responses to different levels of known soil-moisture deficits using four remotely sensed vegetation proxies spanning 2001\u20132018. The thresholds identified represent critical inflection points for changing vegetation responses from highly resistant to highly vulnerable in response to drought stress, and as a warning signal for substantial vegetation impacts. Drought thresholds varied geographically, with much lower percentiles of soil-moisture anomalies in vegetated areas covered by more forests, corresponding to a comparably stronger capacity to mitigate soil water deficit stress in forested ecosystems. Generally, those lower thresholds are detected in more humid climates. State-of-the-art land models, however, overestimated thresholds of soil moisture (i.e. overestimating drought impacts), especially in more humid areas with higher forest covers and arid areas with few forest covers. Based on climate model projections, we predict that the risk of vegetation damage will increase by the end of the twenty-first century in some hotspots like East Asia, Europe, Amazon, southern Australia and eastern and southern Africa. Our data-based results will inform projections on future drought impacts on terrestrial ecosystems and provide an effective tool for drought management.<\/jats:p>","DOI":"10.1093\/nsr\/nwad049","type":"journal-article","created":{"date-parts":[[2023,2,24]],"date-time":"2023-02-24T12:28:38Z","timestamp":1677241718000},"source":"Crossref","is-referenced-by-count":13,"title":["Global variations in critical drought thresholds that impact vegetation"],"prefix":"10.1093","volume":"10","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-7639-7089","authenticated-orcid":false,"given":"Xiangyi","family":"Li","sequence":"first","affiliation":[{"name":"Sino-French Institute for Earth System Science, College of Urban and Environmental Sciences, Peking University , Beijing 100871 , China"}]},{"given":"Shilong","family":"Piao","sequence":"additional","affiliation":[{"name":"Sino-French Institute for Earth System Science, College of Urban and Environmental Sciences, Peking University , Beijing 100871 , China"},{"name":"Key Laboratory of Alpine Ecology and Biodiversity, Institute of Tibetan Plateau Research, Center for Excellence in Tibetan Earth Science, Chinese Academy of Sciences , Beijing 100085 , China"}]},{"given":"Chris","family":"Huntingford","sequence":"additional","affiliation":[{"name":"UK Centre for Ecology and Hydrology , Wallingford OX10 8BB , UK"}]},{"given":"Josep","family":"Pe\u00f1uelas","sequence":"additional","affiliation":[{"name":"CSIC, Global Ecology Unit CREAF-CSIC-UAB , Barcelona 08193 , Spain"},{"name":"CREAF, Cerdanyola de Vall\u00e8s, Barcelona 08193 , Spain"}]},{"given":"Hui","family":
