Linking social media data with geospatial information to analyse changes in human sentiments in and along surface water environments
Social media data represent a valuable source of information on human activity patterns and emotional responses in relation to natural environments. These data can provide insights into the drivers of human sentiments toward freshwater ecosystems, especially in contexts where traditional survey methods are insufficient or resource intensive. A better understanding of the relationship between human sentiments and the perceived value of freshwater environments can support the integration of public perspectives into ecosystem management and regional development. In this paper, we present a replicable method for acquiring, cleaning, and analysing geolocated Twitter data from 2011 to 2018 from Germany. The method includes multiple data cleaning and filtering steps to prepare the dataset for identifying spatial and temporal trends in sentiments and to determine the primary drivers of emotional responses to water bodies. The demonstrated workflow includes the following steps:
• Geo-located Tweets were collected via the Twitter API, then sorted, indexed, and subjected to filtering and cleaning to ensure data quality.
• Language detection and sentiment analysis using a lexicon-based method (Polyglot), suitable for limited computing power, short-text social media sentiment analysis, particularly in the context of analysing the content posted by individuals spending time in freshwater ecosystems.
• Geospatial enrichment, incorporating contextual data such as weather, population density, and other location-based variables
The German Miracle Keeps Running: How Germany's Hidden Champions Stay Ahead in the Global Economy
Despite mediocre macro-economic performance of the German economy, German companies are successful players in global trade. This article explores the strategies of one of the pillars of this export success, the Hidden Champions, Our empirical analysis focuses on leading medium size companies identified by Hermann Simon in the early 1990s, and investigates their long-term progress over one decade. We show that these companies continue to prosper with family ownership combined with professional external management, strategies of market leadership in global niches and a persistent focus on operational effectiveness. Scholars and business leaders, in particular of companies based in other high-cost countries, therefore ought to consider German companies as source for lessons on how to succeed in the global economy
Assessing land use and flood management impacts on ecosystem services in a river landscape (Upper Danube, Germany)
Rivers and floodplains provide many regulating, provisioning and cultural ecosystem services (ES) such as flood risk regulation, crop production or recreation. Intensive use of resources such as hydropower production, construction of detention basins and intensive agriculture substantially change ecosystems and may affect their capacity to provide ES. Legal frameworks such as the European Water Framework Directive, Bird and Habitats Directive and Floods Directive already address various uses and interests. However, management is still sectoral and often potential synergies or trade‐offs between sectors are not considered. The ES concept could support a joint and holistic evaluation of impacts and proactively suggest advantageous options. The river ecosystem service index (RESI) method evaluates the capacity of floodplains to provide ES by using a standardized five‐point scale for 1 km‐floodplain segments based on available spatial data. This scaling allows consistent scoring of all ES and their integration into a single index. The aim of this article is to assess ES impacts of different flood prevention scenarios on a 75 km section of the Danube river corridor in Germany. The RESI method was applied to evaluate scenario effects on 13 ES with the standardized five‐point scale. Synergies and trade‐offs were identified as well as ES bundles and dependencies on land use and connectivity. The ratio of actual and former floodplain has the strongest influence on the total ES provision: the higher the percentage and area of an active floodplain, the higher the sum of ES. The RESI method proved useful to support decision‐making in regional planning.BMBF, 033W024A, ReWaM - Verbundprojekt RESI: River Ecosystem Service Index, Teilprojekt

Integrated water resources management in central Asia: nutrient and heavy metal emissions and their relevance for the Kharaa River Basin, Mongolia
Within the framework of Integrated Water Resources Management (IWRM) the nutrient and heavy metal levels within the Kharaa river basin were investigated. By the application of the MONERIS model, which quantifies nutrient emissions into river basins, various point and diffuse pathways, as well as nutrient load in rivers, could be analysed. Despite seasonal variations and inputs of point sources (e.g. Wastewater Treatment Plant Darkhan) the nutrient concentrations in most of the subbasins are on a moderate level. This shows evidence for a nutrient limited ecosystem as well as dilution effects. However, in the middle and lower reaches heavy metal concentrations of arsenic and mercury, which are linked to mining activities in many cases, are a point of concern. Thus measures are necessary to protect the valuable chemical and ecological status of the Kharaa River and its tributaries. As a result of the growing economic pressure Mongolia will enhance the agricultural production by irrigation. Until 2015 about 60% of the agricultural land shall be irrigated. In addition the gold mining activities shall increase by 20% a year. Both sectors have a high demand for water quantity and quality. The model MONERIS allows the assessment of measures which are inevitable to protect the water quality under shrinking water availability.</jats:p
