Genuine ecotourism can have many positve impacts, particularly the conservation of biodiversity and cultural heritage and the creation of economic opportunities for local communities. While promoting these, it aims to eleminate negative impacts such as environmental degradation, cultural commoditisation and playground effects. Unfortunately, the concept is broadly misunderstood and its true definition is widely debated. It is often used as a marketing tool, with some operators taking advantage of the ecotourism label to attract more business while behaving in environmentally irresponsible ways. This book considers the important topic of quality control and accreditation in ecotourism, describing the mechanisms that can be implemented to ensure quality in all aspects of the industry, namely protected areas, businesses, producs and tour guides.
Valorization of Microalgal Biomass and Wastewater Treatment provides tools, techniques, data and case studies to demonstrate the use of algal biomass in the production of valuable products like biofuels, food and fertilizers, etc. Valorization has several advantages over conventional bioremediation processes as it helps reduce the costs of bioprocesses. Examples of several successfully commercialized technologies are provided throughout the book, giving insights into developing potential processes for valorization of different biomasses. Wastewater treatment by microalgae generates the biomass, which could be utilized for developing various other products, such as fertilizers and biofuels. T...
The enduring changes in the aquatic environment and the increasing influx of contaminants call for novel conceptual and methodological approaches to relating chemical pollution and ecological alterations in ecosystems. This volume highlights the latest advances concerning the sampling, analyses, occurrence, bioavailability, and effects of emerging and priority pollutants in European rivers, the current status of the River Management Plans in Europe, and the applicability of the newly developed techniques for water monitoring purposes. The topics are discussed in the context of the EU Water Framework Directive, evaluating their shortcomings and providing a basis for doing away with them. Linking scientific research and river management practices, this book is an invaluable source of information for environmental chemists, aquatic scientists, ecologists and water managers.
Industrial wastewater can contain many toxic pollutants as well as varying concentrations of organic and inorganic matter. These pollutants can be carcinogenic, mutagenic, or hardly biodegradable, which could cause serious human health risks and also affect other aquatic and terrestrial biota as well. Biological treatment techniques for industrial wastewater, including aerobic and anaerobic digestion, are known to be environmentally friendly, clean, and generally superior to other physicochemical techniques. Aerobic and Anaerobic Microbial Treatment of Industrial Wastewater presents the latest information on multiple bioremediation treatment techniques; summarizes the sources, occurrence, and removal of industrial pollutants; and suggests the most appropriate treatment options for different scenarios. Describes the biochemistry of pollutant removal by aerobic and anaerobic digestion. Highlights emerging pollutants as well as resource recovery techniques from contaminated industrial wastewater. Emphasizes the role of both conventional and innovative novel technologies in aerobic and anaerobic microbial bioremediation of pollutants originated from industrial wastewater.
Ancient Power. Organised Crime. Welcome to Tower City. Matthew Norton is a lawyer facing his darkest days. It was once his job to argue the difference between justice and revenge. He’s no longer sure there is a difference. Finding closure means plunging deep into Tower City’s criminal under-world and waging war with the most bloodthirsty assassin the city has to offer. He’s hired someone who might be able to help; a dangerous outcast with enemies of his own. Together they’ll burn Tower City to the ground if they have to. *** The Firebringer is part one of the Tower City Chronicles. Five books set over five weeks. A fast-paced urban fantasy series like no other!
This 2-volume set constitutes the refereed proceedings of the 9th Iberian Conference on Pattern Recognition and Image Analysis, IbPRIA 2019, held in Madrid, Spain, in July 2019. The 99 papers in these volumes were carefully reviewed and selected from 137 submissions. They are organized in topical sections named: Part I: best ranked papers; machine learning; pattern recognition; image processing and representation. Part II: biometrics; handwriting and document analysis; other applications.
This book offers a comprehensive, unique and up-to-date exploration of diatom ecology spanning from fundamental molecular aspects to the intricate dynamics of metacommunities. In recent years there has been a considerable increase in the amount of research devoted to diatom ecology, with a wide spectrum of approaches. This large amount of information, published in many different journals and books, makes it very difficult to keep up to date, both for the trained researcher and for students. Eduardo A. Morales (d. May 2023) had the original idea to assemble chapters on various subjects within diatom ecology. The questions he posed to potential contributors framed the current book consisting o...
Aquatic plants refer to a diverse group of aquatic photosynthetic organisms large enough to be seem with the naked eye, and the vegetative parts of which actively grow either permanently or periodically (for at least several weeks each year) submerged below, floating on, or growing up through the water surface. These include aquatic vascular plants, aquatic mosses and some larger algae. Aquatic plants are grouped into life forms, each of which relates differently to limiting factors and has distinct ecological functions in aquatic ecosystems. Life form groups include emergent macrophytes (plants that are rooted in sediment or soils that are periodically inundated, with all other structures e...
