Balance Hídrico del Parque Nacional Madidi 2022

The report assesses the water balance of the Madidi National Park (PNM) in Bolivia, focusing on the Tuichi, Hondo, Madidi, and Quendeque basins. Using the WEAP model and data from 1980 to 2015, it finds that forests and wetlands have significantly higher soil moisture retention (66%) compared to agricultural lands and prairies (under 59%). The study highlights that converting forests to prairies or agriculture reduces soil moisture retention by 6.6% to 7.6%, with the greatest impact occurring in May. Annual average precipitation for the basin is 1778 mm, with a runoff coefficient of 0.32. The report recommends establishing new monitoring points within the park and prioritizing water quality analysis in the Tuichi basin due to mining risks.

• The water balance for the basin between 1980 and 2015 shows an average annual precipitation of 1778 mm, actual evapotranspiration of 1206 mm, and runoff of 564 mm, resulting in a runoff coefficient of 0.32.
• Forests and wetlands exhibit a higher average monthly soil moisture retention of 66%, whereas agricultural areas and prairies show lower values of 58% and 59% respectively.
• Land use changes from forest to prairie or agriculture lead to a reduction in soil moisture retention between 6.6% and 7.6%, with the most significant reduction occurring in May, where it can reach nearly 10%.
• The basin's hydrology is highly seasonal: the wet season (December to March) accounts for 58% of annual precipitation and 63% of annual runoff, while the dry season (May to September) accounts for 12% of precipitation and 17% of runoff.
• The Madidi and Tuichi rivers are the most significant contributors to the Beni river's flow from the park, with average flows of 237 m3/s and 165 m3/s respectively at their confluences.
• The park faces critical environmental challenges, including a generalized loss of water recharge capacities and sustained mining contamination, specifically mercury, which threatens local communities and endemic species.
