Situating Hydrological Modeling: A Proposal for Engaging With the Power of Models Open
A growing scholarship suggests hydrological models have political power as they embed and reinforce specific understandings of water and society relations which, in turn, shape future visions of how and for whom water is to be managed. In …

12. On the dialogue between ethnographic field work and statistical modelling Open
Ethnographic and statistical methods have very different epistemological underpinnings; ethnographic research is interpretive, while statistical research is generalizing. Our case study combines these two contrasting approaches and brings …

Regional-scale groundwater analysis with dimensionality reduction Open
Given the importance of groundwater for freshwater provision and groundwater-dependent ecosystems, understanding climate effects on groundwater changes at a regional scale is essential. In this paper, we propose a new way of applying dimen…

Drivers of global irrigation expansion: the role of discrete global grid choice Open
Global statistical irrigation modeling relies on geospatial data and traditionally adopts a discrete global grid based on longitude–latitude reference. However, this system introduces area distortion, which may lead to biased results. We p…

A hybrid data-driven approach to analyze the drivers of lake level dynamics Open
Lakes are directly exposed to climate variations as their recharge processes are driven by precipitation and evapotranspiration, and they are also affected by groundwater trends, changing ecosystems and changing water use. In this study, w…

Making a case for power-sensitive water modelling: a literature review Open
Models are widely used to research hydrological change and risk. However, the power embedded in the modelling process and outcomes is often concealed by claiming their neutrality. Our review shows that in the scientific literature relative…

From situated knowledges to situated modelling: a relational framework for simulation modelling Open
In this paper we extend the use of a relational approach to simulation modelling, a widely used knowledge practice in sustainability science. Among modellers, there is awareness that model results can only be interpreted in view of the ass…

Global patterns of collective payments for ecosystem services and their degrees of commodification Open
This study provides a novel framework for analysing PES-related degrees of ES-commodification. The framework differentiates PES programs by the extent to which ES are traded in a market-like exchange in terms of four PES design components.…

Meta-modeling with data-driven methods in hydrology Open
Process-based models are the standard tools today when trying to understand how physical systems work. There are situations however, when system understanding is not a primary focus and it is worth substituting existing process-based model…

Identifying the drivers of lake level dynamics using a data-driven modeling approach Open
The standard approach of modeling lake level dynamics today is via process-based modeling. The development of such models requires an extensive knowledge about the investigated system, especially the different hydrological flow processes. …

Why rainwater is harvested in different ways and what this means for household water insecurity – findings from a mixed-methods study in rural South Africa Open
<p>Worldwide, rainwater harvesting (RWH) is gaining importance as alternative water source for water insecure households that face drought and water scarcity. RWH is especially useful in the widely dispersed settlements of rural Sout…
