A combination of water management practices has contributed to notable groundwater gains in Central Arizona despite the region dealing with long-term water stress, according to a study led by researchers at The University of Texas at Austin and collaborators in Arizona and Colorado.

In a paper published in Science Bulletin, an international team of scientists examined the extent changes in China’s wetlands from 1980 to 2020 and highlighted the hidden loss and restoration effects based on China_Wetlands product. This consistent dataset (i.e., China_Wetlands) has been created by applying the HOHC method to over 53,000 Landsat images acquired in six time periods from 1980 to 2020.
