• A national assessment of biodiversity and ecosystem services (BES) was initially conducted for Ecuador. • Spatial modeling combined with expert consultation was used for the impact assessment of future scenarios. • Most BES would decrease in the deforestation scenario max. 25 %, while food provision would increase by 5 %. • The climate change scenario revealed that endemic species could be threatened by the ecosystem shift. • Conservation actions are especially urgent in the Amazonian biome which is susceptible to landscape changes. Ecuadorian ecosystems experience high pressure due to anthropogenic activities and climate change. Despite the need of regular monitoring of biodiversity and ecosystem services (BES), attempts to assess the current and future interdependencies of BES and landscape changes are still lacking. This study suggests a spatial assessment of the capacity of ecosystems/land use types to provide BES as status quo and its future development under scenarios of deforestation and climate change. To address data scarcity and improve legitimacy, spatial modeling was combined with participatory approaches. Specifically, changes in landscape pattern were simulated using a modeling platform that combines Geographic Information System (GIS) and Cellular Automaton (CA) modules. Experts in ecosystem conservation and management participated through surveys and workshops. Food, drinking water, service water, soil erosion control, water flow regulation, pollination/seed...
