The four conceptual themes below highlight these gaps, across physical and social science disciplines, on how to integrate predictions of precipitation, hydrology and social science for early action through Early Warning Systems (EWSs):

Multi-Directional Knowledge & Practice Transfer

Gaps around collaboration and the sharing of information across disciplines, agencies, and at-risk communities, as well as the exploration of two-way coupling of models in physical sciences.

(Fisher & Koven, 2020; Pagano et al., 2014; Potter et al. 2021)

Prediction Integration

Involves the exploration of integrating various models, observations, forecasting tools and techniques in research and operations, taking into consideration uncertainty that arises through this cascade of integration

(Abbaszadeh et al., 2022; Imhoff et al., 2020; Pappenberger et al., 2005; Zappa et al., 2011)

Generalizability Of Research Findings

The extent to which findings from research conducted in specific locations, sectors, and contexts (e.g. different land use types, catchment characteristics and population levels) can be compared to other contexts

(Berghuijs et al., 2017; Donovan et al., 2015; Kuller et al., 2021; Lesch et al., 2009; Scolobig et al., 2015)

Increased Data Inputs & Access

Includes the use of alternate data collection and estimation methods and techniques to overcome limitations to data availability, as well as the increased accessibility of data throughout the warning “chain”

(Kidd et al., 2017; Selker et al., 2020; Songchon et al., 2023; Tan et al., 2022)
