The Drina River has always been a source of drinking water and irrigation for food production, with all its tributaries and branching catchment area across the territories of Bosnia and Herzegovina, Montenegro and Serbia. It has connected peoples and cultures for centuries with its bridges. At the same time, with its great head, the Drina has always represented a significant hydropower potential. Throughout history, numerous watermills have been built on it. Currently, there are several constructed hydro-technical facilities on the Drina and in its catchment area. Among them, the most important are dams, with roads over them, associated hydroelectric power plants and belonging structures for flood control, water intakes for drinking water or irrigation. Due to multiple possible, almost always conflicting purposes, as well as several states, entities and other stakeholders, the management of Drina River water resources from the angle of the water-food-energy and climate nexus is an extremely complex problem. In addition to the impact on hydropower, agriculture, forestry, transport, irrigation and drainage, tourism and socio-cultural events, the construction of such strategic structures has also an impact on the climate of the Western Balkans. The issue of optimization within the nexus of the water-food-energy-climate requires holistic research to find synergistic solutions. These solutions are certainly a compromise. But inevitably, they must meet the criteria of sustainable development and the requirements of reducing global warming, according to the set conditions of the adopted European Green Plan for the Western Balkans. This paper proposes a methodology for finding optimal/compromise hydropower solutions, which synergistically include all parameters of influence. Holistic research of sustainable hydropower systems on the Drina River, from the angle of the water-food-energyclimate nexus, is presented. Particularly detailed analyses of the course of the river between the towns of Foča and Goražde, as well as the downstream part between Zvornik and mouth, known as the Lower Drina. In these sections, the most pronounced conflict is whether water will be used for drinking and/or food production and/or energy production and what impact possible solutions have on the climate of the region.

The impact of climate change on the production of hydropower in Mozambique is reviewed and regression analysis is applied to evaluate future climate scenarios. The results show that climate change will cause increased variability of precipitation and create flooding that can damage infrastructure such as hydropower dams. Climate change can also cause drought that will decrease surface water and reduce hydroelectric generation in Mozambique. Electricity generation is to a major extent performed through large-scale hydropower in Mozambique. To fulfill the sustainable development goals (SDGs) and an increased demand for electricity, several large and many small hydropower projects are planned and were built in the country. The economic lifetime of a hydropower plant is typically 100 years, meaning that the hydrologic regimes for the plants should be evaluated for at least this period. Climate change effects are rarely included in present feasibility studies. Economic implications associated with climate change phenomena are higher in Mozambique than in neighboring countries as its future electricity demand to a large extent is forecasted to be met by hydropower. The large hydropower potential in Mozambique should as well be considered when investing in new power plants in southern Africa.

The food–energy–water (FEW) nexus is, by definition, a “wicked problem” in that potential solutions in one sector may inadvertently create perverse effects in another. For example, rapid population growth in conjunction with increasing urbanization will add additional stress to current pressures on the world’s FEW resources. Water scarcity will increase challenges in providing plentiful foods, as well as clean, potable water. Water is also critical to energy production—and conversely—energy is needed to deliver clean, safe water. Extant and projected demand for FEW creates an intertwined problem of supply and demand and new policy considerations for managing the nexus. This study examines the FEW policy tradeoff preferences of the public in California, Idaho, Oregon and Washington states, using survey data collected in 2018. More specifically, this study examines the impact of demographic control variables, FEW knowledge, and environmental values and beliefs on hypothetical tradeoffs between FEW policy preferences. Findings suggest that those respondents that believe in human-caused climate change and with higher new ecological paradigm (NEP) scores were more supportive of water quality issues versus hydroelectric energy production, rural solar energy development versus limiting rural solar development for food production, and water quality over food production for a growing population.

Flood is one of the natural phenomena that often brings loss of property and life. Mostly, it occurs during a high-intensity rainfall event in the catchment area which results in high river flow that cannot be accommodated by river cross sections. In Bandung area, one of the locations that are often hit by the flood is located on km 130 of the Padaleunyi toll road. This flood occurred due to the overflow of the Cilember and/or Cimancong rivers tributary which flows parallel to the toll road, inundating the toll road segment with low elevation at around km 130+500. This paper aims to analyze the effective flood control methods in the above location. With catchment area around 2.3km2, which is relatively small, peak flood discharge calculation was carried out using a rational method. Hydraulics simulation was carried out using HecRas, based on river field measurement data of Cilember and Cimancong river cross-section. Analysis result shows that the combination between flood embankment construction and river normalization provides a significant decrease in flood water level in km 130 Padaleunyi toll road. The reinforced concrete vertical wall was considered as the appropriate flood protections structure due to the limited space available between the river and the toll road segment. This paper also underlined the impact of the increasing loss of water retention areas on an increased risk of flooding.

The importance of assessing hydropower resources in recent years determines the study of the quantitative characteristics of river hydropower. Interesting and at the same time important for understanding the assessment of hydropower potential and its module is a multivariate analysis of the determining factors that determine their magnitude. This approach makes it possible to establish the impact and assess the possible relationship between natural and anthropogenic indicators on its formation. It is especially important to establish the factors that determine the magnitude of the modulus of the hydropower potential, an indicator by which it is possible to reflect the total hydropower of rivers in a spatial context. Since the magnitude of the hydropower potential and its modulus is influenced by numerous factors that may be weakly interdependent, it was decided to apply multivariate analysis to establish the most significant indicators using factor analysis. Studies have shown that hydropower, runoff indicators, catchment area, indicators of erosional activity of the catchment, and indicators of the river’s slope exert the greatest influence on the magnitude of the modules of the hydropower potential. The indicators of plowing, forest cover, and regulation indirectly affect the magnitude of the modulus of the total hydropower potential. In the course of the study, the dependences of the hydropower potential on the catchment area and the average annual water discharge, the module of the hydropower potential and the indicator of the depth of the erosional incision of the rivers were built. The connections are characterized by good degrees of correlation and can be used to calculate the magnitude of hydropower in rivers for which there are no or insufficient input data. In a conclusion, the use of factor analysis made it possible to establish a relationship between all 15 factors, according to 26 hydrological stations, and to identify the main determining factors influencing the formation and spatial distribution of the total hydropower potential module for the Pripyat basin rivers within Ukraine. According to the results of the calculation by the method of factor analysis, five main groups of factors with the corresponding factor load. The first two groups of factors accounted for more than 80% of the total variance of the distribution.

Dammed water reservoirs for drinking water production with their catchment areas and rivers downstream represent dynamic systems that change constantly and are subject to many influences. An optimized management considering and weighing up the various demands on raw water reservoirs (long-term storage for drinking water supply, flood control, ecological state of the rivers downstream, energy production, nature conservation and recreational uses) against each other is therefore very difficult. Thus, an optimal reservoir management has to take into account scenarios of possibly occurring external influences and to permit predictions of prospective raw water qualities, respectively. Furthermore, the impact of short and long term changes in raw water quality on subordinate processes should be considered. This approach was followed in the work presented here, as there currently is no tool available to predict and evaluate the impacts of raw water reservoir management strategies integratively. The strategy supported by the newly developed decision support procedure takes into account all aspects from water quality, flood control and drinking water treatment to environmental quality downstream the reservoir. Furthermore, possible extreme events or changes of boundary conditions (e.g. climate change) can be considered.

Abstract. Drought is an inherent meteorological characteristic of any given region, but is particularly important in China due to its monsoon climate and the “three ladder” landform system. The Chinese government has constructed large-scale water conservation projects since 1949, and developed drought and water scarcity relief frameworks. However, drought still causes huge impacts on water supply, environment and agriculture. China has, therefore, created specialized agencies for drought management called Flood Control and Drought Relief Headquarters, which include four different levels: state, provincial, municipal and county. The impact datasets they collect provide an effective resource for drought vulnerability assessment, and provide validation options for hydro-meteorological indices used in risk assessment and drought monitoring. In this study, we use the statistical drought impact data collected by the Liaoning province Drought Relief Headquarter and meteorological drought indices (Standardized Precipitation Index, SPI and Standard Precipitation Evaporation Index, SPEI) to explore a potential relationship between drought impacts and these indices. The results show that SPI-24 and SPEI-24 are highly correlated to the populations that have difficulties in obtaining drinking water in four out of the six cities studied. Three impacts related to reservoirs and the availability of drinking water for humans and livestock exhibit strong correlations with SPI and SPEI of different accumulated periods. Results reveal that meteorological indices used for drought monitoring and early warning in China can be effectively linked to drought impacts. Further work is exploring how this information can be used to optimize drought monitoring and risk assessment in the whole Liaoning province and elsewhere in China.
