Multi-Temporal Study of Land Use Land Cover Changes
International Journal of Environmental Sciences & Natural Resources, 2021
Anthropogenic activities have profound impact on Land use and land cover (LULC) the world over affecting all abiotic and biotic components in all environments. Studying the effects of past, present and future LULC on forest cover and other dynamic land uses provide valuable information for environmental, land planning and climate change mitigation measures. This study uses a combined methodology of Remote Sensing and Geographical Information System to map historical, current and future LULC through Satellite imagery (Landsat TM, Landsat ETM+, ALOS, Disaster Monitoring Constellation-DMC and SENTINEL) covering Greater Kumasi in a 40-year period. LULC classes such as Agriculture, Built-up, Close Forest, Open Forest, and water were considered based on the predominant geographical sceneries, remote sensing data and field study. Markov Cellular Automata modelling was employed for the estimation of likely LULC changes for the year 2040. The study discovered a perturbing development of forest loss (forest degradation and deforestation), decreasing agricultural activities whiles the Built-up share ballooned. Increasing urbanization at the expense of forest cover and transformation of agricultural lands into human settlements were observed. The forecasted LULC map for 2040 indicated an upward growth in Built up areas at the detriment of the other LULC categories. The outcomes validate the urgent necessity for critical review of regulations in LULC policy strategy, design, and development for the protection of forests and other critical ecosystem services to be preserved. This trend encompassing historical, current and future LULC necessitates that prudent resolutions have to be made to guarantee forest cover, make available land for agriculture and to mitigate the effects of the climate change

Making sense of changes in global patterns of land use or land cover requires drastic simplification. The complexity of changes on the world scale easily defies the most acute and informed observer. But simplification is no simple process. To be useful it must bring out into sharp relief what is most important and relegate to obscurity what can most safely be ignored. Hard decisions and expert judgments are necessarily involved. In making these decisions and judgments we are acutely aware that others might well have been made in their stead, and perhaps with equal justification. We regard our work as a first step that we hope will help others to take long strides toward a more complete understanding of global patterns of landuse and land-cover change. The Objective: A Comprehensive Schema Our aim is to provide a comprehensive analytic framework that will lead to a systematic typology, and ideally a scheme of regionalization, of land-use/land-cover change. We call this framework a schema. Regrettably but inevitably, the framework cannot include every instance of change; we have instead tried to capture the major and most important varieties of land-use and land-cover change. The major changes are those of great magnitude, defined by the area involved or the numbers of people affected. 'The most important changes (a set that obviously intersects with the set of major changes) are distinguished by their criticality from the points of view of human and scientific concern. For instance, certain land-cover changes, even ones small in magnitude, have extreme social costs, while others have few or none. The costly ones we regard as more important from the human point of view. Other changes, not necessarily large in magnitude, have vast consequences from the point of view of biogeochemical fiows or of biodiversity. In concentrating on the largestscale and most important types of land-use and land-cover change we intend also to isolate and identify the most interesting types from the point of view of research
Landscape changes: analysis and classification
2014
T he paper e m phasizes the significance of a correct identification and classification of the selected conditions of the landscape as natural (original) landscape and present land use, which are representative for landscape change analysis. T he natural landscape is reconstructed as a hypothetic state, which existed before the hu m ans entered it. T he present land use is identified by CORINE land cover (CLC) m ethod in 1990 (CLC90) an 2000 (CLC2000). Long-ter m changes were identified by the co m parison of the natural landscape and CLC2000 and classified as urban develop m ent, far m ing expansion, forest and water m anage m ent. Co m parison of the CLC90 and CLC2000 data layers was used for the analysis of short-ter m landscape changes and classified in the context of i m portant driving forces as urbanization, intensification and extensification of agriculture, forestation, deforestation and other changes. T he procedures of identification and classification of the conditions a...
Causes and Trajectories of Land-Use/Cover Change
(Book) Land-Use and Land-Cover Change (E.F. Lambin, H.J. Geist edts.), 2006
One of the key activities of the Land-Use/Cover Change (LUCC) project has been to stimulate the syntheses of knowledge of land-use/cover change processes, and in particular to advance understanding of the causes of land change (see Chap. 1). Such efforts have generally followed one of two approaches: broad scale cross-sectional analyses (cross-national statistical comparisons, mainly); and detailed case studies at the local scale. The LUCC project applied a middle path that combines the richness of indepth case studies with the power of generalization gained from larger samples, thus drawing upon the strengths of both approaches. In particular, systematic comparative analyses of published case studies on landuse dynamics have helped to improve our knowledge about causes of land-use change. Principally, two methods exist for comparative analyses of case studies. These methods are sufficiently broad geographically to support generalization, but at a scale fine enough to capture comple...
The emergence of land change science for global environmental change and sustainability
Proceedings of the National Academy of Sciences, 2007
Land change science has emerged as a fundamental component of global environmental change and sustainability research. This interdisciplinary field seeks to understand the dynamics of land cover and land use as a coupled human–environment system to address theory, concepts, models, and applications relevant to environmental and societal problems, including the intersection of the two. The major components and advances in land change are addressed: observation and monitoring; understanding the coupled system—causes, impacts, and consequences; modeling; and synthesis issues. The six articles of the special feature are introduced and situated within these components of study.
Developing a science of land change: challenges and methodological issues
Proceedings of the …, 2004
Land-change science has emerged as a foundational element of global environment change and sustainability science. It seeks to understand the human and environment dynamics that give rise to changed land uses and covers, not only in terms of their type and magnitude but their location as well. This focus requires the integration of social, natural, and geographical information sciences. Each of these broad research communities has developed different ways to enter the land-change problem, each with different means of treating the locational specificity of the critical variables, such as linking the land manager to the parcel being managed. The resulting integration encounters various data, methodological, and analytical problems, especially those concerning aggregation and inference, land-use pixel links, data and measurement, and remote sensing analysis. Here, these integration problems, which hinder comprehensive understanding and theory development, are addressed. Their recognition and resolution are required for the sustained development of land-change science.
