Abstract. Dams are an important element of water resources management. Data about dams are crucial for practitioners, scientists, and policymakers for various purposes, such as seasonal forecasting of water availability or flood mitigation. However, detailed information on dams on the national level for Germany is so far not freely available. We present the most comprehensive open-access dam inventory for Germany (DIG) to date. We have collected and combined information on dams using books, state agency reports, engineering reports, and internet pages. We have applied a priority rule that ensures the highest level of reliability for the dam information. Our dam inventory comprises 530 dams in Germany with information on name, location, river, start year of construction and operation, crest length, dam height, lake area, lake volume, purpose, dam structure, and building characteristics. We have used a global, satellite-based water surface raster to evaluate the location of the dams. A significant proportion (63 %) of dams were built between 1950–2013. Our inventory shows that dams in Germany are mostly single-purpose (52 %), 53 % can be used for flood control, and 25 % are involved in energy production. The inventory is freely available through GFZ (GeoForschungsZentrum) Data Services (https://doi.org/10.5880/GFZ.4.4.2020.005) (Speckhann et al., 2020).

Abstract Afghanistan has abundant water resources; however, the current state of affairs is dismal because of the lack of integrated water resources management (IWRM) practices and prolonged war and conflict in the country. Therefore, there is a need for a systematic approach to water management, which can be materialized by integrating IWRM and the water–energy–food (WEF) nexus approach to maintain a critical balance of available water resources and their various uses at the national level. This study provides a comprehensive assessment of Afghanistan's water resource management, including the current state, challenges, opportunities, and way forward. The identified challenges are categorized as social and environmental issues, engineering and technical and regulatory, policy and government role. These challenges are inter-connected and a novel framework toward the implementation of IWRM and the WEF nexus in Afghanistan is proposed. This framework can be used by the relevant stakeholders to prepare a roadmap for sustainable management of water resources. Such integrative approaches will enhance Afghanistan's water, food, and energy security and significantly contribute to its economic development. Moving forward, the Afghanistan government must play a crucial role with regards to the efficient management of the country's water resources in an integrated manner as suggested in this paper.

Abstract. Supraglacial, moraine-dammed and ice-dammed lakes represent a potential glacial lake outburst flood (GLOF) threat to downstream communities in many mountain regions. This has motivated the development of empirical relationships to predict lake volume given a measurement of lake surface area obtained from satellite imagery. Such relationships are based on the notion that lake depth, area and volume scale predictably. We critically evaluate the performance of these existing empirical relationships by examining a global database of glacial lake depths, areas and volumes. Results show that lake area and depth are not always well correlated (r2 = 0.38) and that although lake volume and area are well correlated (r2 = 0.91), and indeed are auto-correlated, there are distinct outliers in the data set. These outliers represent situations where it may not be appropriate to apply existing empirical relationships to predict lake volume and include growing supraglacial lakes, glaciers that recede into basins with complex overdeepened morphologies or that have been deepened by intense erosion and lakes formed where glaciers advance across and block a main trunk valley. We use the compiled data set to develop a conceptual model of how the volumes of supraglacial ponds and lakes, moraine-dammed lakes and ice-dammed lakes should be expected to evolve with increasing area. Although a large amount of bathymetric data exist for moraine-dammed and ice-dammed lakes, we suggest that further measurements of growing supraglacial ponds and lakes are needed to better understand their development.

In this article, a general methodology for simulation of water resources management is suggested. The research has been conducted in three different levels: a deep analysis of the historical management procedures, the development of some alternative ways to optimal management, and the establishment of planning criteria at short, middle, and long term. The main constraints, divided into three categories according to the severity of probable losses, have been defined as a function of several expected goals: hydro power, flood control, recreational activities, etc. The model was applied with excellent results to the upper region of the St. François river basin (Québec, Canada). Key words: simulation, resources management, mathematical models, optimization.

AbstractThe main goal of the article is to present some differences in the practice of competency management, perceived as a part of human resources management, that were identified in the empirical research conducted in three countries, that is Poland, Spain, and Austria. Our research is placed within cross-cultural HRM and comparative HRM, that together with corporate-international HRM make three theoretical and research streams within international human resources management (IHRM). This is because on one side, the analysis of the research data covers comparison of competency management systems and practices both at the organizational and national level in different countries, but on the other side, we make an attempt to discuss the possible influence of national culture on identified differences.

Abstract. According to the International Disaster Database (CRED 2009) frequency of extreme hydrological situations on a global scale is constantly increasing. The most typical example of a natural risk in Europe is flood – there is a decrease in the number of victims, but a significant increase in economic damage. A decrease in the number of victims is caused by the application of current hydrological management that focuses its attention primarily on large rivers and elimination of the damages caused by major flood situations. The growing economic losses, however, are a manifestation of the increasing intensity of floods on small watercourses, which are usually not sufficiently taken into account by the management approaches. The research of small streams should focus both on the study of the watercourse itself, especially its ecomorphological properties, and in particular on the possibility of flood control measures and their effectiveness. An important part of society’s access to sustainable development is also the evolution of knowledge about the river landscape area, which is perceived as a significant component of global environmental security and resilience, thanks to its high compensatory potential for mitigation of environmental change. The findings discussed under this contribution are based on data obtained during implementation of the project "GeoRISK" (Geo-analysis of landscape level degradation and natural risks formation), which takes into account the above approaches applied in different case studies – catchments of small streams in different parts of the Czech Republic. Our findings offer an opportunity for practical application of field research knowledge in decision making processes within the national level of current water management.

The article assesses the food security of one region of Kazakhstan - the East Kazakhstan region. In the analyses, criteria such as the level of the region’s food independence, the degree of satisfaction of the population’s physiological needs in basic food, and the level of economic availability of food were applied. The research has shown that the food security in the East Kazakhstan region was at an acceptable level. However, some threats to food security were identified, including: a high level of income differentiation among the households of the East Kazakhstan region, an increase in the price index for food products, and a significant proportion of the population with incomes below the subsistence minimum. The results of the evaluation can be useful for creating agri-food policy measures that will ensure, maintain and improve the level of food security at both a regional and national level.
