Climate change, inter‐annual precipitation variability, recurrent droughts and flash flooding,
coupled with increasing water needs, are sha** the co‐evolution of socioeconomic and …

Tropical regions cover approximately 36% of the Earth's landmass. These regions are home
to 40% of the world's population, which is projected to increase to over 50% by 2030 under a …

Tracer‐aided studies to understand plant water uptake sources and dynamics in tropical
ecosystems are limited. Here, we report the analysis of dry season source water uptake …

Nitrate legacy is affecting groundwater sources across the tropics. This study describes
isotopic and ionic spatial trends across a tropical, fractured, volcanic multi‐aquifer system in …

Abstract The volcanic Barva and Colima multiaquifer system is crucial for the drinking water
supply of about 1.7 million people, about 30% of the population in Costa Rica. The …

Groundwater springs are critical to achieving Sustainable Development Goals (SDG 6,
access to clean water) in the Himalaya and remain highly vulnerable to climate change and …

Dissolved organic carbon (DOC) transport and export from headwater forests into
freshwaters in highly dynamic tropical catchments are still understudied. Here we present a …

Under a changing climate, projections estimate that over the next thirty years, extreme
Tropical Cyclones (TCs) will increase in frequency, with two to three times more Category 4 …

There is still limited understanding of where stream water originates, their flow paths, how
water sources mix, and for how long water transits montane tropical catchments. Here, we …

Abstract This Scientific Briefing presents results from a nearly 10‐year hydrometric and
isotope monitoring network across north‐central Costa Rica, a region known as a headwater …
