Download or read book The Role of Ecosystems in Disaster Risk Reduction written by Fabrice G. Renaud and published by United Nations University Press. This book was released on 2013 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: The uptake of ecosystem-based approaches for disaster risk reduction (DRR) is slow, however, despite some success stories. There are multiple reasons for this reluctance: ecosystem management is rarely considered as part of the portfolio of DRR solutions because the environmental and disaster management communities typically work independently from each other; its contribution to DRR is highly undervalued compared to engineered solutions and therefore not given appropriate budget allocations; and there are poor interactions between policymakers and researchers, leading to unclear and sometimes contradictory scientific information on the role of ecosystems for DRR. The aim of this book is to provide an overview of knowledge and practice in this multidisciplinary field of ecosystems management and DRR. The contributors, professionals from the science and disaster management communities around the world, represent state-of-the-art knowledge, practices, and perspectives on the topic.

Download or read book Classical management theories and organisational performance in Rivers State Nigeria An analysis written by Newman Enyioko and published by GRIN Verlag. This book was released on 2021-07-19 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Academic Paper from the year 2021 in the subject Business economics - Business Management, Corporate Governance, , language: English, abstract: The study examined the relationship between Management (classical) theories and organisational performance in Rivers State, Nigeria. The paper assessed the level of application of the scientific management, administrative and bureaucratic theories in Nigeria organizations with emphasis in Rivers State and their contributions to the organisational performance (productivity and growth) of the surveyed organisations. A sample of 378 staff based on Taro Yemane formula was investigated. Descriptive and inferential statistical tools were used to analyse the data generated in this study. Copies of a questionnaire were used to collect data from the respondents. Also, 316 copies of questionnaire were found valid and relevant for utilization in the study resulting to an overall usable response rate of 83.60 %. The study revealed that the application of the scientific management, administrative and bureaucratic theories in the management of various organizations contributed to low productivity, non-growth, productivity, slow pace of organizational growth and development in the organizations. The study concluded that given the present performances of Nigerian organizations, more needs to be done in the manner and way classical management theories were applied. Workers will be more motivated to perform in a conducive work environment if classical theories are applied with high track of efficiency while reducing unnecessary bureaucracy. It was recommended that, for organizations to achieve the objective of effective and efficient productivity, they must understand, accommodate, embrace and promote people who are dynamic and proactive in the organisation. Organizations should also review periodically their rules, regulations and manuals to ensure current trends in the business environment. Finally, organizations should allow for initiative, innovations and workers participation in decision making.

Download or read book Thermus Species written by Richard Sharp and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is considerable interest in thermophile microorganisms, in their environments, their ability to survive at temperatures which normally denature proteins, but more importantly, as a valuable resource for bio technology. The first reported isolation of Thermus by Tom Brock was in 1969. This initiated the present era of thermophilic research with the realization that where liquid water is available, there may be no limits to the temper ature at which microorganisms can grow. Considerable research into the ecology, physiology, metabolism, and thermostable enzymes of thermo philes has led to their evaluation for a range of industrial and commercial processes. The past fifteen years have been an explosive period of dis covery of many new genera and species, including the descriptions of a new fundamental kingdom-the Archaea. Much of the current research has been focused on the Archaea; but it is significant that during this period, the original type strain YT-l of Thermus aquaticus described by Brock has provided a major step forward in molecular biology. DNA polymerase from strain YT-I has proved to be the major success in the commercialization of enzymes from thermophilic microorganisms to date. The ease with which Thermus strains can be handled in laboratories without specialized equipment, together with the large investment in de scribing their structure, metabolism, and genetics, should ensure a con tinuing effort in Thermus research.
Download or read book Bioremediation of Agricultural Soils written by Juan C. Sanchez-Hernandez and published by CRC Press. This book was released on 2019-03-14 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quality of agricultural soils are always under threat from chemical contaminants, which ultimately affect the productivity and safety of crops. Besides agrochemicals, a new generation of substances invades the soil through irrigation with reclaimed wastewater and pollutants of organic origin such as sewage sludge or cattle manure. Emerging pollutants such as pharmaceuticals, nanomaterials and microplastics are now present in agricultural soils, but the understanding of their impact on soil quality is still limited. With focus on in situ bioremediation, this book provides an exhaustive analysis of the current biological methodologies for recovering polluted agricultural soils as well as monitoring the effectiveness of bioremediation.
