Reconstructing historical forest cover change in the Lower Amazon floodplains using the LandTrendr algorithm [PDF]
Acta Amazonica, 2016 The Amazon várzeas are an important component of the Amazon biome, but anthropic and climatic impacts have been leading to forest loss and interruption of essential ecosystem functions and services.

Annual Impervious Surface Data from 2001–2020 for West African Countries: Ghana, Togo, Benin and Nigeria [PDF]
Scientific DataImpervious surface data are increasingly important for research and planning. Despite the availability of global and local urban land cover maps, regional data are lacking in Africa. We generated annual 30 m impervious cover data from 2001–2020 for Ghana,

Long-term vegetation changes in elephant-related areas of concern in Kruger National Park, South Africa. [PDF]
Ecol ApplAbstract African elephants, whether alone or in combination with other environmental factors such as floods, droughts, fire, and other herbivores, have significant impacts on large savanna trees, often contributing to declines over time. However, their effects on woody vegetation in general remain less well understood.

Dynamic monitoring of urban built-up object expansion trajectories in Karachi, Pakistan with time series images and the LandTrendr algorithm. [PDF]
Sci Rep, 2021 AbstractIn the complex process of urbanization, retrieving its dynamic expansion trajectories with an efficient method is challenging, especially for urban regions that are not clearly distinguished from the surroundings in arid regions. In this study, we propose a framework for extracting spatiotemporal change information on urban disturbances. First,

Grassland Research, Volume 4, Issue 2, Page 175-189, June 2025.This study utilized the LandTrendr algorithm to monitor shrub disturbances on the Qinghai‐Tibet Plateau from 1990 to 2022. The findings indicate that climate, topography, and grazing are the primary drivers of shrub disturbances, providing valuable scientific evidence for ecological monitoring.
