Impacts of forests and forestation on hydrological services in the Andes: A systematic review

Bonnesoeur, V., Locatelli, B., et al. 2019 Forest Ecology and Management, 433 Several Andean countries have planned to restore forest cover in degraded land to enhance the provision of multiple ecosystem services in response to international commitments such as the Bonn Challenge. Hydrological services, e.g. water supply, hydrological regulation and erosion mitigation, are particularly important to sustain the life of more than fifty million Andean people. While rapid and important forest cover changes have occurred during recent decades, critical information on the impact of forestation on hydrological services has not yet been synthesized in the context of Andean ecosystems. To help [...]

Impacts of forestation on water and soils in the Andes: What do we know?

Bonnesoeur, V., Locatelli, B. and Ochoa-Tocachi, B.F., 2018. CIFOR Info Brief 237 This brief summarises the findings of a systematic review on the impacts of forestation on water and soils in the Andes (detailed in Bonnesoeur et al., 2018). Exotic tree plantations and, to a lesser extent, native forests consume water and therefore often reduce the total water supply to downstream users in most Andean regions. Only in areas immersed in clouds, such as in the eastern slope of the Andes, might native forests increase downstream water availability compared to other land covers. Decreased total water supply could be acceptable to [...]
