“…other large-sized bird species, for example, Charadriiformes and Gruiformes (e.g. Stewart et al 2007;Zieliński et al 2007) and bats (Chiroptera;Trille et al 2008;Jain et al 2010;Ferri et al 2016), for which, it could be useful to obtain risk indices based on ecological traits. In this regard, further field and analytical research is necessary.…”

In wind-farm impact assessments, it is useful to know the level of uncertainty that characterizes some key variables used to assess the sensitivity to risk in species of conservation concern. Here, we have introduced the use of the Shannon entropy as a value of ecological uncertainty of the prediction of the risk assessment index, obtained from two ecological traits (flight altitude and flight type). We based our evaluation of risk sensitivity on sampling of three common raptor birds (Gyps fulvus, Falco tinnunculus, Buteo buteo) all co-occurring in a wind farm landscape (central Italy). As to flight altitude, Gyps fulvus prefers the flight altitude category > 300 m, Falco tinnunculus categories closer to the ground, Buteo does not show clear preference for a particular flight altitude category. As regards the flight type, Gyps fulvus showed significant preference for circular and thermal flight patterns, Falco tinnunculus for rapid horizontal/vertical flight patterns, while Buteo was found to prefer constant directions and circular and thermal flight patterns. Multiplication of the scores associated with these eco-behavioural traits by the number of recorded occurrences allowed estimation of risk sensitivity used to compute the risk assessment index. We normalized the partial scores of the risk associated with these traits with H' values, thus obtaining more reliable species-specific normalized risk indices. The greater the entropy, the greater the level of uncertainty associated with it, and the lower the reliability of the risk index. Therefore, the entropy associated with flight behaviour diversity (altitude or type) could be a proxy for assessing uncertainty in wind power impact assessment. We think that normalizing indices of risk by including a measure of uncertainty can support decision makers in bird conservation and wind farm management.

“…Use the relevant mechanical equipment to discharge the mud at the bottom of the river, and reduce the harmful substances and precipitated pollutants in the water through the mud removal method. Since the rock-containing substances are generally deposited on the surface of the river bottom mud, the mud removal by this method can also effectively reduce the mud and the total rock content and further expand the water capacity of rivers and lakes [20,21]. It can effectively reduce pollution of rivers and lakes and improve the water quality of rivers and lakes and the surrounding environment.…”

With the rapid development of industrial and agricultural production, the rapid growth of population, and the acceleration of urbanization, the problem of water pollution is becoming more and more serious. Water shortages and pollution disrupt the balance of ecosystems and seriously limit people’s health and rapid economic development. Nowadays, the method of repairing sewage bodies using microbial landscape aquatic plants is attracting more and more attention, and it is a big challenge to maintain the sustainable development of human beings and nature. This paper uses floating rafts to combine microorganisms and landscape aquatic plants to conduct sewage treatment experiments. According to microorganisms, landscape aquatic plants absorb nutrients in the water body, examine the changes in water quality during the restoration of microorganisms’ landscape aquatic plants, and establish the growth of microorganisms’ landscape aquatic plants. The relationship with changes in water quality aims to provide a theoretical basis for the treatment of slow-flowing water bodies such as lakes, reservoirs, large artificial ponds, and rivers. In this paper, the experiments are divided into four groups (A (experimental sewage + microbial inoculant), B (experimental sewage + plant), C (experimental sewage + microbial inoculant + plant), and D (experimental sewage)). It can be divided into the total nitrogen content, total phosphorus content, and COD value data, and chromaticity detection of each group of the test is continuously monitored weekly to comprehensively detect and observe the repair effect on contaminated water bodies. The experiment proved that the water quality of the three treatment groups was significantly clearer than that of the blank control group, and its clarity: microorganism + plant > microorganism > plant > blank control group. This shows that the combination of microorganisms and landscape aquatic plants can effectively reduce the various pollutants contained in sewage and reduce the color of sewage. Treating sewage using plant technology that combines microorganisms is feasible and promising.

“…Similarly, other authors affirmed that repowering wind power plants with fewer but larger turbines can reduce the mortality of birds impacts [83,84,89,93,102]. In contrast to previous studies, in 2016, Ferri et al analyzed the impact of a repowered wind power plant located in central Italy on bats [86]. They considered not only the mortality of bats due to collision, but also the habitat changes and disturbances.…”

The integration of renewables into power systems is a key transformation for mitigating climate change and reducing fossil-fuel dependence. Among the different resources, wind participation has become crucial in recent decades—both onshore and offshore wind power plants. However, assuming the useful life of the wind turbines at approximately 20 years, different solutions should be discussed to overcome the turbine’s aging problem. In the coming years, some countries within the wind sector will face the decision of partially or totally repowering or dismantling their turbines. This paper reviews different repowering strategies and contributions from a multifactorial perspective. A set of categories is defined by the authors and those multifactorial parameters are then classified according to such categories: technical, economic, environmental, social, and political. From each category, the most relevant factors to be considered for repowering decision-making purposes are identified and discussed. According to the specific literature, more than 90% of the reviewed contributions are focused on onshore wind power plant repowering actions. This percentage is in line with onshore and offshore wind generation units installed in recent decades. The reviewed studies show that Germany has a major number of contributions. Regarding offshore repowering strategies, all contributions propose a multifactorial analysis, in contrast to onshore repowering strategies where only 68% of the authors carry out a multifactorial analysis. The revised repowering methodologies and the categorization of factors can also be used by the repowering market, as a useful tool in the near future.
