This book was released on 2012-03 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land Use/Land Cover Change has been one of the widely experienced environmental phenomena as a result of unbalanced man-nature interaction. Land which is central in our civilization is greatly affected by human interventions such as settlement, agriculture and other development activities which in turn are contributing to land use and land cover changes. The issue of land cover dynamics driven by a population influx and lofty demand for land resource are highly contributing to the changes in local environment and thereby impacting the livelihood strategies of the local people. As people utilize the land for various purposes, the process challenges their existing livelihood systems and in the long run their sustainable livelihood strategies. Moreover, land cover dynamics have become one of the principal contributing factors for climate change and global warming through altering the earth's ecosystem. All these impacts of land cover dynamics are being experienced by inhabitants of the Menagesha Suba locality which is found some 45 kilo meters south west of Addis Ababa, Ethiopia.

Download or read book Land Cover Dynamics and Urban Sprawl Indicators written by Karen K. Underhill and published by . This book was released on 2004 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted to identify land cover patterns and trends in the period of 1972 through 1999 as the indicator of urbanization in Kansas City metropolitan including five study counties using satellite remote sensing techniques. The study also analyzed other urbanization-related variables to determine which can serve as additional indicator(s) of urban sprawl. Supervised image classification technique was implemented on three satellite images (1972, 1985, and 1999). This classification delineated five land cover types on the satellite imagery: residential built-up land, commercial built-up land, forestland, non-forest vegetation, and water. The remote sensing results revealed that land cover change in the study area was significant over the 27-year time frame. Generally, commercial and residential land cover increased while forest and non-forest vegetation decreased. This landscape modification was spatially diverse with varied rates of change among the five individual study counties. The study suggests that remotely sensed land cover dynamics is a reliable indicator of urban sprawl. Other urbanization-related variables including population, major road, and housing were analyzed in comparison with remotely sensed land cover data. Population analysis indicated that the population changes had similar patterns as that of the built-up areas generated from the remote sensing analysis. This suggests that the population's spatial and temporal distribution can serve as a good indicator of urban sprawl if used alone or combined with remotely sensed land cover data. The buffer analysis on the roadway data was conducted using GIS. The results showed that this analysis could help reveal the relationship between the major roads and the major land cover type along the roads. However, to fully understand the impact of the roads on urbanization, more detailed information is needed, such as the history of road construction and modification. The housing analysis indicated that housing data could have a good correlation with remotely sensed residential land cover changes while the relationship between this data set and other land cover types were weak. This result suggests that housing information can be used in conjunction with other indicators to help verify the process of urban sprawl.

Download or read book Advancing Land Change Modeling written by National Research Council and published by National Academies Press. This book was released on 2014-03-31 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: People are constantly changing the land surface through construction, agriculture, energy production, and other activities. Changes both in how land is used by people (land use) and in the vegetation, rock, buildings, and other physical material that cover the Earth's surface (land cover) can be described and future land change can be projected using land-change models (LCMs). LCMs are a key means for understanding how humans are reshaping the Earth's surface in the past and present, for forecasting future landscape conditions, and for developing policies to manage our use of resources and the environment at scales ranging from an individual parcel of land in a city to vast expanses of forests around the world. Advancing Land Change Modeling: Opportunities and Research Requirements describes various LCM approaches, suggests guidance for their appropriate application, and makes recommendations to improve the integration of observation strategies into the models. This report provides a summary and evaluation of several modeling approaches, and their theoretical and empirical underpinnings, relative to complex land-change dynamics and processes, and identifies several opportunities for further advancing the science, data, and cyberinfrastructure involved in the LCM enterprise. Because of the numerous models available, the report focuses on describing the categories of approaches used along with selected examples, rather than providing a review of specific models. Additionally, because all modeling approaches have relative strengths and weaknesses, the report compares these relative to different purposes. Advancing Land Change Modeling's recommendations for assessment of future data and research needs will enable model outputs to better assist the science, policy, and decisionsupport communities.

Download or read book Impact of Climate Change Land Use and Land Cover and Socio economic Dynamics on Landslides written by Raju Sarkar and published by Springer Nature. This book was released on 2022-01-03 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the impact of climate change, land use and land cover, and socio-economic dynamics on landslides in Asian countries. Scholars recently have brought about a shift in their focus regarding triggering factors for landslides, from rainfall or earthquake to claiming rapid urbanization, extreme population pressure, improper land use planning, illegal hill cutting for settlements and indiscriminate deforestation. This suggests that the occurrence or probabilities of landslides are shaped by both climate-related and non-climate-related anthropogenic factors. Among these issues, land use and land cover change or improper land use planning is one of the key factors. Further climate change shapes the rainfall pattern and intensity in different parts of the world, and consequently rainfall-triggered landslides have increased. These changes cause socio-economic changes. Conversely, socio-economic and lifestyle changes enhance inappropriate land use and climate change. All these changes in land use, climate and socio-economic aspects are dynamics in nature and shape landslide risks in Asian countries, where they are given serious attention by governments, disaster management professionals, researchers and academicians. This book comprises 21 chapters divided into three major sections highlighting the effect of climate change on landslide incidence with the influence on vegetation and socio-economic aspects. The sections address how climate change and extreme events have triggered landslides. The advances in geospatial techniques with the focus on land use and land cover change along with the effect on socio-economic aspects are also explored.

Download or read book Using Ecosystem Services to Understand the Impact of Land Cover Change a Case Study of the Upper San Pedro Watershed written by David Joseph Chan and published by . This book was released on 2013 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: In arid and semiarid environments, various natural and anthropogenic stressors have resulted in land cover change that has negatively impacted the ecological integrity of the landscape. Society, however, relies on many ecological processes and functions provided by the landscape to enhance its wellbeing. The direct and indirect benefits society receives from the landscape are collectively termed "ecosystem services." The overarching goal of this thesis was to examine how the landscape has changed and to analyze how these changes impact the ecosystem services supplied by the landscape. The Upper San Pedro watershed in southeastern Arizona and northern Sonora was used as a case study to link land cover change with an array of ecosystem services to understand the spatiotemporal dynamics of ecosystem service supply. To accomplish this, a multitemporal land cover dataset for the watershed was updated to extend the temporal coverage to 37 years across 5 land cover datasets. Indicators serving as proxy variables for a variety of ecosystem services were assessed for each land cover class. This linkage between land cover and ecosystem services enabled an analysis of the tradeoffs and synergies within the array of services each land cover class can provide. Combined with the multitemporal land cover dataset, the spatiotemporal dynamics of potential ecosystem service supply were analyzed across the watershed for a 37 year period. Rather than examining the impacts of land cover change on the biophysical aspects of the environment, this approach enables land managers and decision makers to explore the implications of a changing landscape on human wellbeing.

This book was released on 2019-11-26 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: The availability and distribution of water resources in catchments are influenced by various natural and anthropogenic factors. Human-induced environmental changes are key factors controlling the hydrological flows of semi-arid catchments. Land degradation, water scarcity and inefficient utilization of available water resources continue to be important constraints for socio-economic development in the headwater catchments of the Nile river basin in particular over the Ethiopian Catchments. This research investigates the impact of landscape anthropogenic changes on the hydrological processes in the Upper Tekeze basin (A tributary of the Nile). The hydrology of the basin is investigated through analysis of hydro-climatic data, remote sensing techniques, new field measurements and parsimonious hydrological models. The empirical evidence provided in this book confirms that human-induced environmental changes can significantly change the hydrology of catchments, both in negative (degradation) and in positive (restoration) ways. This book also shows that rainfall-runoff relationships in semi-arid catchments are non-uniform and hence the application of hydrological models in such catchments need special attention. Moreover, parsimonious dynamic hydrological model improves our understanding of the hydrological response to dynamic environmental changes.

Available in PDF, EPUB and Kindle. Book excerpt: Specifically, the paper identifies and analyzes several direct drivers of deforestation and forest degradation in Ethiopia including: forest clearance for both subsistence and large-scale agriculture; illegal and unsustainable extraction of wood mainly for charcoal and firewood; overgrazing; and recurrent forest fires. It also reviews underlying drivers including: rapid population increase and the associated growing demand for land and energy; extensive legal and institutional gaps including lack of stable and equitable forest tenure; lack of stakeholder participation in forest management and benefit-sharing schemes; and weak law enforcement. These drivers and the dominant actors behind them – ranging from small-scale subsistence farmers to national and global investors – are discussed in the context of the political economy, including the policy and institutional framework of the country. The implications of the overall forest condition to the objectives and requirements of REDD+ are evaluated, and key issues that need to be addressed for efficient, effective and equitable implementation of REDD+ are discussed. These key issues include: reconciling the apparently contradictory policies and programs, particularly those that negatively affect the forestry sector; improving the forest tenure and governance system; augmenting economic return from forests to communities and individuals; creating more efficient and effective forest institutions at all levels; and enhancing sectoral and regional coordination among implementing agencies.

Download or read book Earth Science and Applications from Space written by National Research Council and published by National Academies Press. This book was released on 2007-10-01 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural and human-induced changes in Earth's interior, land surface, biosphere, atmosphere, and oceans affect all aspects of life. Understanding these changes requires a range of observations acquired from land-, sea-, air-, and space-based platforms. To assist NASA, NOAA, and USGS in developing these tools, the NRC was asked to carry out a "decadal strategy" survey of Earth science and applications from space that would develop the key scientific questions on which to focus Earth and environmental observations in the period 2005-2015 and beyond, and present a prioritized list of space programs, missions, and supporting activities to address these questions. This report presents a vision for the Earth science program; an analysis of the existing Earth Observing System and recommendations to help restore its capabilities; an assessment of and recommendations for new observations and missions for the next decade; an examination of and recommendations for effective application of those observations; and an analysis of how best to sustain that observation and applications system.

Download or read book Environmental Change and Agricultural Sustainability in the Mekong Delta written by Mart A. Stewart and published by Springer Science & Business Media. This book was released on 2011-05-13 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mekong Delta of Vietnam is one of the most productive agricultural areas in the world. The Mekong River fans out over an area of about 40,000 sq kilometers and over the course of many millennia has produced a region of fertile alluvial soils and constant flows of energy. Today about a fourth of the Delta is under rice cultivation, making this area one of the premier rice granaries in the world. The Delta has always proven a difficult environment to manipulate, however, and because of population pressures, increasing acidification of soils, and changes in the Mekong’s flow, environmental problems have intensified. The changing way in which the region has been linked to larger flows of commodities and capital over time has also had an impact on the region: For example, its re-emergence in recent decades as a major rice-exporting area has linked it inextricably to global markets and their vicissitudes. And most recently, the potential for sea level increases because of global warming has added a new threat. Because most of the region is on average only a few meters above sea level and because any increase of sea level will change the complex relationship between tides and down-river water flow, the Mekong Delta is one of the areas in the world most vulnerable to the effects of climate change. How governmental policy and resident populations have in the past and will in coming decades adapt to climate change as well as several other emerging or ongoing environmental and economic problems is the focus of this collection.
