Book Description
Bachelor Thesis from the year 2019 in the subject Environmental Sciences, Federal University of Technology, Owerri, course: Environmental Technology, language: English, abstract: This research work seeks to study the effects of anthropogenic activities on the Nworie and Otamiri river morphology in Imo State Nigeria. Using land use/ land cover change analysis to evaluate the degree of the effect anthropogenic activities have on the morphology of the river and the major human divers causing this geomorphic change to the catchment. GIS was a major tool for the analysis of aerial photographs gotten from Landsat 5, 7 and 8 satellites. The images from years 1986, 2000 and 2016 were all analysed and land use/ land cover were classified into 5 classes namely water body, light forest, thick forest, bare surface and built up area. Questionnaire was used to retrieve data during the field work. 100 respondent answers were analysed to gain information about observed human activities around the study area. The combined results from the analysed images and questionnaires formed the basis of the research findings. The findings of the research suggest morphological change to the Nworie and Otamiri River. This is primarily as a result of human activities such as farming, dumping of refuse, building of structures like roads, sand mining and dredging. This activities cause the widening and narrowing of the River banks. In order to protect the river morphology, strict government policies that protect environmental landforms from degradation must be implemented and stringent penalties should be awarded to defaulters.

Book Description
This book discusses current knowledge and challenges with the ecological management and conservation of wetlands, with a focus on the East Kolkata Wetlands of India. This area is referred to as a Ramsar Site, a designation given to areas with special protection statuses, since it is the largest natural waste recycling system in the world. The site faces many threats to its biodiversity and ecosystem functioning due to anthropogenic activity in the region, and therefore an assessment of the ecosystem services, bio-ecological uniqueness, and issues stemming from climate change and human impacts is needed to develop protection strategies for the future ecological functioning and sustainability of the wetlands. The authors use GIS and remote sensing techniques to assess and monitor harmful industrial and environmental impacts on the wetlands, and to inform mitigation and conservation strategies in the face of ongoing threats such as pollution, habitat destruction and bioinvasion. The book also highlights various social and economic aspects tied to the functioning and management of the wetlands, along with ecological, biological, and physio-chemical considerations. The study will be of use to students and researchers in aquatic ecology, biodiversity, and environmental sustainability and conservation, as well as to environmental planners, engineers, and policymakers.

Book Description
This book focuses on how to maintain environmental sustainability as one of its main principles, and it addresses how smart cities serve to diminish wastes and maintain natural resources by having clean green energy that is operated by new smart technology designs. Living in a smart city is not something of the future anymore, it is here, and it is being implemented all over the world. A smart city uses different types of electronic Internet of things (IoT) sensors to collect data and then use these data to manage assets and resources efficiently. The smart city concept integrates information and communication technology (ICT), and various physical devices connected to the IoT network to optimize the efficiency of city operations and services and achieve sustainable solutions to allow us to grow with proper management of our resources. Smart sustainable structures and infrastructures face the need of urban areas due to the growth of populations while in the same time save our environment. To achieve this, we need to revisit the conventional methods in design and construction and the conventional materials which are used now to optimize the design and provide smart solutions. In the past few years, the consumption of resources has been massive, and the waste produced from that consumption has been inconceivable. This is causing environmental degradation, which produces many environmental challenges, such as global climate change, excessive fossil fuel dependency and the growing demand for energy. As well as, discussing the challenges facing the civil engineering design and construction of smart cities components and presenting concepts and insight from experts and researchers from different civil engineering disciplines., this book explains how to construct buildings and special structures and how to manage and monitor energy.

Book Description
This textbook provides a comprehensive review of the problems associated with the supply of drinking water in the developed world. Since the first edition of this book was published, water companies and regulators have been presented with numerous new challenges - global warming has seriously affected water supplies and water quality; advances in chemical and microbial analysis have revealed many new contaminants in water that were previously undetectable; and recent terrorist attacks have demonstrated how vulnerable water supplies are to contamination or disruption. This new edition includes an overview of the current and emerging problems, with potential solutions. It has been completely updated, and includes the WHO Revised Drinking Water Guidelines. An ideal textbook for courses in environmental science, hydrology, environmental health and environmental engineering; it also provides an authoritative reference for practitioners and professionals in the water supply industry.

Book Description
Pre-University Paper from the year 2019 in the subject Pedagogy - General, grade: 1.0, , language: English, abstract: This study was undertaken to find out what are the common experiences of students in participating extra-curricular activities. Also this study aims to know on how students cope up the difficulties they’ve experienced while joining extra-curricular activities. Only fifteen selected students are involved in the research, thus we recommend that they must gather more respondents in order for them to generalize the views and experiences of the students for having an extra-curricular in school. Based on the data that we gathered from all of our respondents that are involved in extra-curricular activities, many of them share the same experiences regarding their participation on ECA. They gain experiences that positively affect them and can be used to improve and enhance not only their grades but their skills and their personality as a student and as a person. For all the students who have extra-curricular activities, researchers recommend that if they will involve to this kind of activity, they should balance their time management in order to not affect their academic performance. In addition, for students who wants to have extra-curricular activities, we recommend that they should prioritize their academics first before other things so that they could not suffer difficulties especially when it comes to projects, assignments and tests.
