Abstract

Soil moisture plays a critical role in the hydrological cycle, ecosystem productivity, and climate regulation. This study presents a bibliometric analysis of soil moisture estimation using remote sensing in Brazil, based on 99 scientific articles published between 1995 and 2024. The analysis reveals increasing scientific production, particularly after 2010, and highlights recurring themes such as MODIS, SMAP, energy balance, and agricultural drought. Although research has advanced in recent years, it remains uneven across Brazil's biomes and limited in the application of advanced tools such as machine learning. The findings suggest that remote sensing has become a strategic tool for monitoring soil moisture, with growing importance for climate change adaptation and water resource management. By identifying knowledge gaps and thematic trends, this work contributes to a more integrated and regionally relevant research agenda, supporting sustainable land and water use across South America.
