Abstract

Estuaries connect terrestrial and marine biomes. Their ecological functioning is essential for marine matter fluxes, while their central economic role as transport hubs persists throughout history and has become ever more pronounced. Managing complex socio-ecological systems such as estuaries can benefit from an ecosystem service approach. The challenge is to combine highly complex knowledge, prone to uncertainties, to policy relevant information. This paper introduces a knowledge-based ecosystem service screening, applied in a participatory manner by including different stakeholders from four industrialized NW-European estuaries.The approach allowed to efficiently engage stakeholders from different, often opposing sectors, in order to derive a set of ecosystem services of high societal importance, link them to supply by habitats, and explore inter- and intra-estuarine variability. By introducing the notion of trade-offs and synergies and assessing these for estuaries, the interconnectedness and mutual interests for estuarine management measures were indicated. The screening is based on knowledge surveys among experts. Statistical reliability was acceptable, but to complement the assessment, quantitative validation on a local scale would be useful.Ecosystem service assessments, especially when engaging stakeholders, can inform policy on strategies for the sustainable use of ecosystem services in intensively used and ecologically fragile estuarine zones.

Highlights

  • Antibiotics are amongst the most commonly prescribed medicines to children [1,2,3]

  • In many countries, limited access to comprehensive patient-level data, due to confidentiality/privacy issues, could be a major obstacle. Apart from overcoming this limited data access, it would be very useful to have a tool for quantifying pediatric use in large aggregated datasets, where age stratification is missing

  • As liquid dosage forms are available for many antibiotics, we hypothesized that their consumption can be linked to pediatric antibiotic use and drug-related data can be translated to a patient-related measure

Summary

Introduction

Despite the frequent pediatric use, comprehensive data are available for only few countries [4,5,6]. In many countries (including Hungary), limited access to comprehensive patient-level data, due to confidentiality/privacy issues, could be a major obstacle. Apart from overcoming this limited data access, it would be very useful to have a tool for quantifying pediatric use in large aggregated datasets (e.g. the European Surveillance of Antimicrobial Consumption, or ESAC-net database), where age stratification is missing. As liquid dosage forms are available for many antibiotics, we hypothesized that their consumption can be linked to pediatric antibiotic use and drug-related data can be translated to a patient-related measure. We aimed to quantify and benchmark Hungarian pediatric antibiotic use
