Abstract. Land-use and land-cover change (LUCC) is a key factor in determining regional vegetation greenness, impacting terrestrial carbon, water, energy budgets. As global LUCC hot spot, Southeast Asia has experienced intensive cropland plantation expansion over the past 50 years; however, impacts of these changes on greenness have not been elucidated. Here, we harmonized multiple datasets, used satellite-derived leaf area index (LAI) combination with machine learning approach to quantify insular (i.e. Peninsular Malaysia, Sumatra, Borneo). We found that LAI shows almost no trend (0.04 × 10−2 m2 m−2 yr−1) from 2000 2016: net effect an increased (+5.71 due CO2 fertilization offset by decreased mainly (−4.46 yr−1). The impact croplands contrasts India China. Meanwhile, oil palm climate induced only small decreases (−0.41 −0.38 yr−1, respectively). Our research unveils how different processes offers quantitative framework assess under land-use scenarios.
