  abstract = {{O}n a worldwide scale, land use and land cover changes ({LULCC}) is a major driver of global change and biodiversity erosion. {T}his study aims to monitor at the scale of {S}ri {L}anka, {LULCC} and vegetation dynamics, to identify the main changes and their drivers. {I}t places emphasis on multiscale geospatial monitoring with satellite data but also mobilises the interdisciplinary knowledge of a research programme. {F}irst, national scale data allows the identification of major changes with the {MODIS} {NDVI} dataset using {M}ann-{K}endall tests and time profile analysis. {A} second local scale was mobilised with a systematic diachronic visual interpretation of high-resolution images on {G}oogle {E}arth. {T}he third step, a macro-regional scale focus on the {S}outh and {E}ast coasts, used {LANDSAT} imagery ({S}tacked {K}-means) verified by field studies (botanical and vegetation analysis, and interviews). {A}bout 92.5% of the island of {S}ri {L}anka is stable or presents no significant trends in the vegetation cover. 5% show a significant positive (greening) trend between 2000 and 2020 around the {P}uttalam lagoon, west of the {S}amanalawewa {R}eservoir, in the {U}dawalawe {N}ational {P}ark, east and north of {E}lla, and the {N}uwaragala {F}orest {R}eserve. {O}nly about 2.5% (165,000 ha) of the {I}sland shows a negative significant trend mainly in the periphery of {C}olombo and {T}rincomalee. {T}he first driver is a set of national planning decisions in terms of infrastructure development (including urban growth, housing programmes and agricultural fields, and the management of protected areas). {T}he second driver comes under rural dynamics with increasing tree density in rural landscapes over the {U}va {P}rovince. {I}nfrastructure development initiated by the state, creates both underlying conditions for other activities and negative impacts on coastal ecosystems, such as degradation of wetlands (including protected areas).},
