Quantitative Indicators & Metrics of Ecosystems Services, Health & Function

The challenges of mapping the capacity of landscapes to deliver aquatic ecosystem
services (AES) are extensive, especially considering service assessment across scales
varies from the regional to national levels. Aquatic ecosystems are hierarchically
organized, and thus depend on processes that may occur far beyond the sites where
AES are delivered (e.g., nutrient distribution across watersheds and its impact on local
lake fish productivity). As a consequence, we need quantitative spatial frameworks to
generate hydrological data at several scales that can then serve as predictors against
known values of AES, which in turn can be used as a way to predict key ecosystem
services.

Key Objectives:

Utilize and further develop the HydroSHEDS database (Lehner et al. 2008) –
a framework to generate consistent data and tools at multiple spatial scales to facilitate
eco-hydrological modelling by generating information regarding watershed boundaries,
drainage directions, flow accumulation, river networks, and others

Assess effects of single or multiple stressors in the river network through the use of
HydroSHEDS model environment

Develop quantitative spatial frameworks to generate hydrological data at several scales
that can predict key ecosystem services

Development of a Global River Classification (GloRiC), which will aim to derive functional
ecosystem classifications based on physical and biological parameters at global and
regional scales in order to better understand and recognize the various characteristics
of habitats and their inter-connections
