The Pantanal, the world’s largest tropical wetland, experienced unusual drying in 2000–2021, but the causes are poorly understood. …

The Optical TRApezoid Model (OPTRAM) has been extensively utilized to map high-resolution surface soil moisture (top 0–5 cm) using …

Brazil holds 16% of the world’s freshwater, yet its water systems are still not fully understood. To understand how rainfall and rivers interact across the country, we studied the hydrologic signatures of 735 catchments. Through catchment classification we identified six major water behavior groups, mostly based on how wet or dry the regions are. In drier areas, climate drives streamflow; in wetter ones, soil and land features matter more. This helps map and predict when and where floods or droughts are likely to happen and it also guides smarter water storage and usage in vulnerable regions. Ultimately, this research supports better planning for a changing climate.

This study aims to better understand flash droughts worldwide and their varying characteristics and impacts. We surveyed the experiences of people affected by flash droughts and then examined a wide range of literature, including non-English and nonacademic sources. This helped us understand how flash droughts can differ from those commonly studied in the United States and China. We identified and described five types of flash droughts, some of which may not be detected by current drought measurement methods. It is crucial to include all types of flash droughts in drought monitoring systems and management plans, as they are expected to become more common due to global warming. We can then better prepare for and reduce the impacts of this growing threat.

Smallholder agriculture is critical for current and future food security, yet quantifying the sources of smallholder yield variance …

We assessed how advanced soil properties maps can improve soil moisture modeling using a Land Surface Model. The results showed that using contemporary soil properties maps and pedotransfer functions to estimate soil properties improved soil moisture modeling performance, especially when soil properties data is available at different soil layers.
