Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Studienarbeit aus dem Jahr 2018 im Fachbereich BWL - Sonstiges, , Sprache: Deutsch, Abstract: The study material on the ¿Application of Remote Sensing and GIS in Fisheries¿ is a humble attempt to convey the physical understanding about the techniques like GIS and Remote sensing to the students from fisheries. Realizing the need for a material describing the application especially in fisheries sector, it was my fervid aspiration to develop a text book.The Worlds highest producer of fish and fishery products from capture fisheries are identified as major fishing areas by FAO. The countries within the Southeast Asian region considered as a major producer of capture fisheries. In 2019, the world¿s fisheries production was amounted to 195.7 million metric tons (MT) of which, 94.6 million MT was from capture fisheries and 101.1 came from aquaculture. Southeast Asian region accounted for about 42.2 million MT that constitute around 22% of the total landing. Among them, Indonesia, the highest producer generated about 20.6 million MT.Considering this scenario, the effective management of the region¿s inland and coastal areas is very essential to reinforce the trend of fisheries and aquaculture in geographical region and thereby can ensure food security of peoples within the whole world. There are existing technologies that would be used for better planning and management of fisheries and aquaculture, e.g. GIS and Remote Sensing technologies. The usage of those technologies is therefore worth exploring, especially in obtaining the required information for formulating appropriate approaches, policies, further as management plans for medium and long-term sustainable utilization of fishery resources and environmental facilities for fisheries and aquaculture.

Taschenbuch. Zustand: Neu. Neuware -Reliable information and sound assessment methods about the ecosystem enable for identification of indicator species in order to predict changes occurring in the ecosystem. Information about a given ecosystem might be collected both by ground-based and remote sensing methods. Ground-based methods of data acquisition include field observations and gathering in-situ data, while data collection using remote sensing is based on the use of image data acquired by sensors of different types. Remote sensing technology is used to collect data on inaccessible sites. This is because remote sensing enables to collect data about the area at a distance without direct contact with the object under investigation. At present, there is a need for advanced technologies in different areas such as ecosystem management, inventories and assessment of biodiversity, environmental monitoring and species-habitat suitability analysis. These technologies should be based on physical parameters of the ecosystem and socio-economic situations of the community. Therefore, remote sensing is used to evaluate the health of the ecosystem in general by monitoring the dynamics of the earth¿s surface.Books on Demand GmbH, Überseering 33, 22297 Hamburg 56 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The status of eutrophication is explained in terms of trophic status index (TSI) by Carlson in 1977 by using secchi disc depth, chlorophyll and total phosphorus in the water bodies. He ranked the water bodies in 0-100 ranks & accordingly classified them in trophic status from ultra-oligotrophic to hyper-eutrophic. The process of eutrophication is due to increase in the nutrients in the water bodies, which affects the primary production and ultimately the fish fauna in the water body. A sudden increase in algal bloom due to high nutrient may affect the aquatic organism by gill chocking and creating low oxygen in the water body. So, the managers of large water bodies give due importance to monitor the water quality parameters of the lagoon/lake/reservoirs. Collecting water quality parameters from the large water bodies periodically is a difficult task, time consuming and costly affair. To reduce the time, manpower and cost, remotely sensing imagery and GIS platform can be used to monitor the water quality and trophic status of the water bodies.Books on Demand GmbH, Überseering 33, 22297 Hamburg 68 pp. Englisch.

The countries within the Southeast Asian region considered as a major producer of capture fisheries. GIS is within the sort of hardware, software, and data that permits any trained staff to update, manipulate, analyze, and display geographically the referred information (Rahel, 2004). Since GIS integrates hardware, software, and data for capturing, managing, analyzing, and displaying all varieties of geographically referenced information, it can provide the unlimited amount of data needed in research (Foote and Lynch, 2015). In fact, GIS has many applications associated with planning, management, transport/logistics, insurance, telecommunications, and business (Maliene et al., 2011). Foote and Lynch (2015) added that the various innovations, like GIS could boost the region¿s efforts to enhance fisheries development and management as it links variety of technologies, and thus it emerges as a strong technology.Books on Demand GmbH, Überseering 33, 22297 Hamburg 52 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Remote sensing and Geomorphology are two disciplines of science, where geomorphology is the science of study of landforms of the earth. It is concerned with pattern of landform, materials and their related processes. Geomorphology as a science deals with evolutionary processes of relief forms of the earth and lead us to understand various processes of evolution of landforms.Remote sensing is the science of acquiring information about an object or phenomena close to the earth¿s surface by measuring electromagnetic radiation. Remote sensing is an effective tool that enables understanding of aerial and satellite images containing integrated information¿s of the features on the ground such as landform, ecology, available resources and impact of human interference on the natural landscape. The present collection of articles is the result of research study undertaken in different field areas of Assam. Land use and land cover change (LULC) is one of the focal themes in geomorphic study. It has great significance in analysis of changing nature of land use practices, causes of increasing intensity of resource use and changing relationship between Man¿s activities with nature.Books on Demand GmbH, Überseering 33, 22297 Hamburg 140 pp. Englisch.

Taschenbuch. Zustand: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - As a result of industrialization and urbanization, soft land cover on the earth surface is replaced with low reflective artificial materials. Surface temperature fluctuations are highly influence by these land cover changes. Onsite measuring of land surface temperature (LST) is a time consuming and a crucial task. Therefore, scientists suggest deriving land surface temperature by using remote sensing techniques. Satellite images are the key elements which are used to obtain LST as well as change detections of surface cover. Urban heat islands of a given area can be extracted according to the derived LST values. This book describes the methods that can be used to obtain LST values, heat island areas and preparation of thermal risk maps by using satellite images.

Taschenbuch. Zustand: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - There is evidence of unprecedented land use change in the Koga watershed with far-reaching consequences for the long-term sustainability of the natural resource. Thus, the objective of this study was to characterize the hydrological elements and Land use/Land cover changes of Koga watershed, Mecha Woreda-West Gojjam. The watershed has been analyzed using the SRTM 20 meter optimum spatial resolution and the Land use/Land cover changes were also examined using the Land sat (TM) satellite images of 1986 and 2011 (ETM+) collected during the dry seasons (March). The result of the study reveals that cultivated land and settlements were the predominant land use during the specified periods. Conversely, grazing land and forest land declined by 10.39 %, 3.05 % and 0.23% respectively. In contrary, cultivated land and settlement expanded by 12.67 %. For these changes, population pressure and high demands of land were the main factors and had an adverse effect on the hydrologic response of the study area. Therefore, this book has a gigantic importance for researchers on how to characterize hydrological elements and Land use/Land cover changes using remote sensing and GIS.
