Nevertheless, the practicability of applying this procedure at pilot-scale has not been explored before as an integrated process. This work presents an overview of the technological applications of microalgae for the treatment of wastewater from swine farms and the by-products (pigments, polysaccharides, lipids, proteins) and services of commercial interest (biodiesel, biohydrogen, bioelectricity, biogas) generated during this process. Furthermore, the environmental benefits while applying microalgae technologies are discussed.Agriculture is responsive to weather and climate variability. In addition to the climatic stressors, coastal agriculture is influenced by non-climatic factors. Therefore, understanding farmers' perception of the causes of their changes in farm management plays a key role in motivating them to adopt agricultural adaptations. The aim of this study was to investigate the changes in coastal farm management in Bangladesh over the last decade compared to the previous one. We explored whether the causes of those changes were climatic or non-climatic as perceived by the farmers and the factors that shaped their perceptions. We interviewed 381 farmers sampled from ten subdistricts along the coast of Bangladesh. Descriptive statistics showed that the farmers had changed on average 10 to 11 farm management practices. Though the average value was 67%, a higher number of farmers in the western coastal zone mentioned that climate change had impacts on their farm management. Adoption of rice crop-related adaptations was greater than livestock, fisheries or general agricultural practices. According to the discriminant function analysis, discriminative variables were perception of climatic impacts on farm productivity, climate change awareness, involvement with non-farm jobs, age, education, organizational affiliation, number of changed farm practices, and meteorologically consistent perception of rainfall and temperature. Lessons learned from this research are that the farmers should better understand the link between climate change and farm management practices while motivating them to implement adaptation strategies. https://www.selleckchem.com/products/guanosine-5-triphosphate-trisodium-salt.html This could be achieved by improving farmers' climate change awareness, perceptions of changes in climatic parameters and involvement with farm-related associations.Communities with contaminated lands are also often the most vulnerable to the impacts of a changing climate such as sea-level rise, increased temperatures, and extreme storms and hurricanes due to socio-economic and historic reasons - some of the very factors that enable the creation of these contaminated sites in these communities. In spite of, and arguably because of, this double exposure and impact, the ability of these communities to clean up and reuse their contaminated lands has not kept up with their need. Researchers have often attributed this discrepancy to a lack of technical capacity and human resource. To address this lack, since January 2018, students enrolled in planning-related courses offered by the University of West Florida Department of Earth and Environmental Sciences have engaged with stakeholders on the redevelopment of superfund sites located in Pensacola, FL under the auspices of the USEPA's College Underserved Community Partnership Program. The engagement centered on the reuse of two of these superfund sites for the betterment of the stakeholders' socio-economies and their biophysical environments. I focus in this paper on four examples of engaging with students in planning for superfund site remediation and redevelopment. The examples are of engaging with county staff; collaboratively engaging with city staff and a private firm; engaging with county commissioners; and engaging with a private firm between two superfund sites over the course of one year. I highlight the contextual, unique needs, of each stakeholder group yet emphasize the applicable lessons across all four examples. I also focus on best practices to develop plans and outlines for mutually beneficial products and outcomes for both students and stakeholder groups in the process of land revitalization.Recreational use of nature areas is increasing worldwide. All trail-based activities have a certain degradation effect on vegetation and soil, and conflicts between conservation values and recreation may occur. Controversy still exists regarding the relative impact of mountain bikers compared to hikers on trails. In this study, we manipulated the use intensity from hikers and mountain bikers on existing, natural-surfaced trails, and investigated effects of increased use and the relative importance of mountain biking on trail degradation. In two study sites, two trails were selected, one designated for hiking and one for biking. Passes were counted with TRAFx counters. The proportion of mountain bikers on the designated biking trails was on average 47%, and on the hiking trails 13%. Trail width and depth were recorded at permanently marked transects repeatedly throughout the growing season, and analyzed with linear mixed models as a function of number of passes, proportion of bikers and environmental conditiond negative impacts of increased use. For such management actions to be successful, they need to be targeted towards the actual user groups and the natural conditions in the area.The new sustainable development goals (SDGs) call for actions to close the gap between the protection of the environment and the socio-economic development. To shed light on the link among economy, society, and ecology, this study assesses the ability of renewable energy to moderate the effects of CO2 emissions on human development and economic growth for 31 transitional economies. Our findings substantiate that (i) CO2 emissions have unconditional negative effects on human development and economic growth; (ii) the net impacts on human development and economic growth are positive from the interplay between renewable energy and CO2 emissions, i.e. renewable energy reduces the influences of per capita CO2 emissions on human development and economic growth; (iii) renewable energy interacts with CO2 intensity and CO2 emissions from liquid fuel consumption to negatively influence economic growth and human development. To dampen these net negative effects, corresponding renewable energy thresholds were computed and discussed.
