Abstract: Agricultural production in Brazil has increasingly relied on groundwater extraction, raising concerns about the sustainability of underground reservoirs. This paper compares the diffusion of the two most common types of wells used to extract groundwater for agriculture in the state of São Paulo, Brazil: conventional (low depth) and tubular (high depth). We use longitudinal muni-cipal-level information and spatial panel models to analyze the two main drivers of groundwater extrac-tions: climate variability (aridity) and environmen-tal conservation (conservation agriculture and native forest conservation). Our results highlight how incre-asing aridification in the dry season (winter) has redu-ced the diffusion of conventional wells and increased the diffusion of less sustainable tubular wells. We also highlight that soil conservation and native forest pre-servation practices reduce the need for deep under-ground water extraction

Resumen: En Brasil, la producción agrícola depende cada vez más de la extracción de agua subterránea. Ello genera preocupaciones sobre la sostenibilidad de las reser-vas subterráneas. Así pues, este artículo compara la difusión de los dos tipos de pozo más comunes para extraer agua del subsuelo para la agricultura, en el estado de São Paulo: convencional (baja profundidad) y tubular (alta profundidad). Se usaron datos longitu-dinales de nivel municipal y modelos de panel espacial, a fin de analizar los dos principales estimuladores de la extracción de agua subterránea: la variabilidad cli-mática (aridez) y la conservación ambiental (agricultura de conservación y conservación de flora nativas). Los resultados destacan que la creciente aridez en la estación seca (invierno) ha reducido la difusión de pozos convencionales y ha aumentado la difusión de pozos tubulares menos sostenibles. A su vez, las prácticas de conservación del suelo y los bosques nati-vos reducen la necesidad de extracción de aguas sub-terráneas profundas
