Other aspects are challenging for farming: a semiarid to semihumid climate (600–1300 mm annual rainfall) with a six-month dry season and sufficient fresh groundwater restricted to roughly one-third of the region, two-thirds being without groundwater or with groundwater of high salinity.

25 lip 2024 · The Gran Chaco is a large, dry forest in South America that has been heavily deforested, particularly in the dry Chaco subregion. This deforestation, mainly driven by the expansion of the agricultural frontier, has changed the land's characteristics, affecting the local and regional climate.
The climatic diversity is also impressive, including permanently frozen areas, vegetation-free mountain zones, deserts, jungles with torrential streams, and huge alluvial plains, which may change abruptly.
The climate is subtropical with frequent frosts during the winter months. The Dry Chaco receives about 20 inches of precipitation annually in summer (November through March), when moist air from the Atlantic Ocean moves across the Amazon basin and is deflected southward by low altitude jet streams.
