The Creation

Floods, at present, may constitute the natural phenomenon with the greatest impact on the deterioration of cultural heritage, which is the reason why the study of flood risk becomes essential in any attempt to manage cultural heritage (archaeological sites, historic buildings, artworks, etc.) This management of cultural heritage is complicated when it is distributed over a wide territory. This is precisely the situation in the region of Castile and León (Spain), in which 2155 cultural heritage elements are registered in the Catalog of Cultural Heritage Sites of Castile and León, and these are distributed along the 94,226 km2 of this region. Given this scenario, the present study proposes a methodological framework of flood risk analysis for these cultural heritage sites and elements. This assessment is based on two main processing tools to be developed in addition: on the one hand, the creation of a GIS database in which to establish the spatial relationship between the cultural heritage elements and the flow-prone areas for different flood return periods and, on the other hand, the creation of a risk matrix in which different variables are regarded as associated both to flood hazard (return period, flow depth, and river flooding typology) and to flood vulnerability (construction typology, and construction structural relationship with the hydraulic environment). The combination of both tools has allowed us to establish each cultural heritage flood risk level, making its categorization of risk possible. Of all the cultural heritage sites considered, 18 of them are categorized under an Extreme flood risk level; and another 24 show a High potential flood risk level. Therefore, these are about 25% to 30% of all cultural heritage sites in Castile and León. This flood risk categorization, with a scientific basis of the cultural heritage sites at risk, makes it possible to define territories of high flood risk clustering; where local scale analyses for mitigation measures against flood risk are necessary.

Environmentally Sensitive

This paper approaches the environment impact mitigation measures adopted in the Cabiu´nas-Reduc-3 project (Gasduc-3), completed in January 2010. This high complexity project has great strategic importance to the Company and for the extension of natural gas offer in Brazil. Due to the large size of the project and its interference with environmentally sensitive areas, several programs and actions have been carried out in the influenced areas what allowed the team to conclude Gasduc-3 and, at the same time, follow through with the premise of sustainable development.

Weather Situation

Air traffic contributes to anthropogenic global warming by about 5% due to CO2 emissions and non-CO2 effects, which are primarily caused by the emission of NOx and water vapor as well as the formation of contrails. Since—in the long term—the aviation industry is expected to maintain its trend to grow, mitigation measures are required to counteract its negative effects upon the environment. One of the promising operational mitigation measures that has been a subject of the EU project ATM4E is climate-optimized flight planning by considering algorithmic climate change functions that allow for the quantification of aviation-induced climate impact based on the emission’s location and time. Here, we describe the methodology developed for the use of algorithmic climate change functions in trajectory optimization and present the results of its application to the planning of about 13,000 intra-European flights on one specific day with strong contrail formation over Europe. The optimization problem is formulated as bi-objective continuous optimal control problem with climate impact and fuel burn being the two objectives. Results on an individual flight basis indicate that there are three major classes of different routes that are characterized by different shapes of the corresponding Pareto fronts representing the relationship between climate impact reduction and fuel burn increase. On average, for the investigated weather situation and traffic scenario, a climate impact reduction in the order of 50% can be achieved by accepting 0.75% of additional fuel burn. Higher mitigation gains would only be available at much higher fuel penalties, e.g., a climate impact reduction of 76% associated with a fuel penalty of 12.8%. However, these solutions represent much less efficient climate impact mitigation options.

ABSTRACT Response actions and mitigation measures, undertaken at the time of a spill specifically to protect seafood resources can ultimately influence the duration, magnitude and extent of impacts. Understanding if and why particular measures were successful (or not) in minimising or eliminating damages to a particular fishery or mariculture installation is important for the seafood sector to use, either in planning, or when faced with making a choice as to what measures may be best to protect their resource. This paper reviews small-scale (in terms of volume spilled) cases in which ITOPF has been involved from around the world where fisheries or mariculture were an important concern and where measures were implemented specifically to mitigate damage. By evaluating whether any trends, or criteria exist under which certain measures or actions are likely to be successful or unsuccessful, contingency plans can be adapted to provide more practical, tailored guidance. Furthermore, policy and research objectives could be directed towards damage prevention rather than the quantification, assessment and remediation of impacts.

Aims: Explore the perceptions of flower farms workers towards the health effects of chemical exposures. Perception is the views, attitudes and opinions of workers. Study Design: Descriptive survey, using quantitative and qualitative approaches. Place and Duration of the Study: Tana Flora, Bahir Dar Farm and Tal Flowers, between November 2018 and June 2019. Methodology: Statistical analyses were done using 302 sample workers (80 male and 222 female; age ranges 15-65 years) at 95% confidence interval employing stratified random sampling techniques via proportional sample selection, and a response rate of 95.6%. Independent sample t-test with the assumption of equal variance (the Leven’s t-test) was used to analyze the existence of significant perception differences among female and male workers, and workers labour divisions. Qualitative data was obtained through structured interviews from farms managers (3); regional Environmental, Forest and Wildlife Protection Development Authority (EFWPDA) officials (3) and field observations that supplemented the quantitatively analyzed data. Results: Leven’s t-test showed the computed p-values were less than the preset significance level (0.05) for the majority of health impacts of chemical exposures. Significant perception differences were observed among male and female workers and workers of different labour divisions (production vs. protection; pack house vs. protection) towards health impacts: skin rush, appetite loss, stomach cancer, birth defects, reproductive system damage, dizziness and impaired sight. Males perceived in a better way than females since farms gave special focus to male workers in the protection section 27(8.9%) and they engaged using the required health protective gears. Further, in flower farms, most of the proposed health impact mitigation measures were poorly implemented. Conclusion: Workers perception differences were occurred due to a particular attention to male workers in protection labour division; hence the regional EFWPDA should do the proper supervision and follow up for effective implementation of health impact mitigation measures.
