Soil moisture is a critical component for Earth science studies, and Synthetic Aperture Radar (SAR) data have high potential for retrieving soil moisture using backscattering models. In this study, polarimetric SAR (PALSAR: Phased Array type L-band Synthetic Aperture Radar) data and polarimetric decompositions including span, entropy/H/alpha, and...

Many developing countries in Asia are experiencing rapid urban expansion in climate hazard prone areas. To support climate resilient urban planning efforts, here we present an approach for simulating future urban land-use changes and evaluating potential flood exposure at a high spatial resolution (30 m) and national scale. As a case study, we...

Peatlands in tropical regions like Indonesia are undergoing irreversible subsidence due to changes in land use (e.g., deforestation) and land management practices (e.g., drainage alteration), resulting in massive amounts of soil...

This dataset contains GIS maps (.shp files) of built-up/urban land in the Philippines in 2018 (current) and 2050 (future), considering low/medium/high future urban expansion scenarios. The 2050 urban area maps were generated using a cellular automata logistic regression model, which was applied to historical urban area maps and other openly...

Globally, shifting cultivation is known to be an important driver of tropical deforestation. However, we argue that it can be sustainably managed if the environmental boundary conditions, laid by the traditional customs and practices, are fully respected. We narrate an empirical study from the Zunheboto district of Nagaland, India, where we...

Lichen is an important food source for caribou in Canada. Lichen mapping using remote sensing (RS) images could be a challenging task, however, as lichens generally appear in unevenly distributed, small patches, and could resemble surficial features. Moreover, collecting lichen labeled data (reference data) is expensive, which restricts the...

The novel coronavirus (SARS-CoV-2) is the third coronavirus this century to threaten human health, killing more than two million people globally. Like previous coronaviruses, SARS-CoV-2 is suspected to have wildlife origins and was possibly transmitted to humans via wet markets selling bushmeat (aka harvested wild meat). Thus, an interdisciplinary...

Widespread urban expansion around the world, combined with rapid demographic and
climatic changes, has resulted in serious pollution issues in many coastal water bodies. To help
formulate coastal management strategies to mitigate the impacts of these extreme changes (e.g.,
local land-use or climate change adaptation policies), research...

Water scarcity, together with the projected impacts of water stress worldwide, has led
to a rapid increase in research on measuring water security. However, water security has been
conceptualized under different perspectives, including various aspects and dimensions. Since public
health is also an integral part of water security, it is necessary...

Biodiversity knowledge is communicated by scientists to policymakers at the biodiversity “science-policy interface” (SPI). Although the biodiversity SPI is the subject of a growing body of literature, gaps in our understanding include the efficacy of mechanisms to bridge the interface, the quality of information exchanged between science and policy...
