The Application of Remote Sensing in Vegetation Cover, Sudan | Chapter 8 | Cutting Edge Research in Biology Vol. 5

 This paper wanted to review several studies on the use of detached sensing in Sudan accompanying a focus on plants cover in various domains by many scholars; the unification of remote thinking in the gum Arabic belt; pertaining to the south Gadarif region; ahable and chunk grabou area, silver Nile state with a devote effort to something the amount and mapping of land use land cover change through plan and monitoring the changes that happen in land use land cover, due to dryness, climate change, and transgression; east of the Nile Khartoum State, and in the middle during a half-of one hundred years. Following are recommendations came from these studies: the use of assessment signs including NDVI, SAVI, and PCA –maneuvered in color composite and/or unsupervised categorization can be secondhand as an appropriate mean for rangeland monitoring and amount which was urged from the study of North Kordofan state.

The Assessment of the Impact of Climate Change on Land Use in Port Harcourt: Nigeria | Chapter 13| Current Perspectives to Environment and Climate Change Vol. 4

 

Land is a natural resource which is a scare commodity. It is therefore important to classify land and
Land Use. The city of Port Harcourt has experienced a lot of changes on Land Uses and Land Cover
which has had an impact on the spatial pattern of the city. This study hopes to identify how the varying climatic changes and elements have affected the spatial pattern of Port Harcourt and to ensure that there is sustainable development. The methodology used was Geographic Information Systems (GIS) and remote sensing which provided a cost effective and accurate alternative to understanding landscape dynamics. Digital change detection techniques based on multi-temporal and multi-spectral remotely sensed data was also used. Objectives of the Study are to examine the spatial pattern of Port Harcourt between the periods of 1984 –2014. To ascertain how climatic factors have affected the spatial pattern in Port Harcourt. To determine the present state of Land Use and Land Cover in Port Harcourt and how it has been affected by climatic elements. The result of the study showed that there have been climatic deviations in rainfall and temperature values and very obvious changes in the spatial pattern of Land Use and Land Cover between 1984 to 2014. The Built – Up area showed an increase from 16.50% in 1984 to 51.38% in 2014. A lot of development has taken place using up most of the Gallery Forest, Vegetation area and the Water Bodies. Development of Built – Up area needs to be controlled so that all of the vegetation is not used up because the city needs some vegetation to allow the city breath.

Land Cover Dynamics in Tanzania Part of Kagera River Basin: A Strategy for Sustainability of Lake Victoria | Chapter 6 | International Research in Environment, Geography and Earth Science Vol. 1

This study is reporting on an investigation done to assess land cover dynamics in Tanzania part of Kagera River Basin (KRB) over a period of 21 years i.e.1990-2011 using Remote Sensing, Hydrology and GIS as a basis for initiating policy interventions for sustainability of Lake Victoria ecosystem. Hitherto, the extent of land cover changes in the KRB have not been quantified with the view of assessing the extent of exploitation of the natural resources in the area and its subsequent impact on the trans-boundary Lake Victoria water resource. The assessment is important firstly, for identification of causative factors and secondly, as a mechanism for formulating necessary interventions to that effect. Specifically, Landsat 5, Landsat 7 and ETM+ (2000) satellite images were used. Eight Land Cover classes were identified namely, Forests, Woodland, Bush land, Cultivated Land, Swamps, Grassland, Bare land and Urban areas. Hydrographical data were used to assess changes in quantity of water flowing from the KRB into Lake Victoria and relating it with land cover dynamics in KRB at in the period of study. Spatial data processing, analysis and interpretation were carried out in ERDAS Imagine and ArcGIS software environments; while water quantity data and other non-spatial data were processed and analyzed in Microsoft Excel application 2007.  The study revealed a significant decline of vegetation cover and water quantity discharged from Kagera River to Lake Victoria over the study period. This contravenes the Global efforts of ecological sustainability, urging avoidance of depletion of natural resources for maintenance for ecological balance. These results are early warning to the Management of Lake Victoria of its potential failure towards achievement the Millennium Development Goal on responsible consumption and protection of natural resources in proximity of Lake Victoria. The Management of Lake Victoria in collaboration with other relevant authorities should thus, initiate remedial measures to control none strategic use of vegetation cover in KRB for sustainability of Lake Victoria and its ecosystem.
