Download or read book The Impacts of Climate Change and Human Activities on the Structure and Function of Wetland Grassland Ecosystems written by Zhongqing Yan and published by Frontiers Media SA. This book was released on 2023-10-31 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands and grassland are important components of natural ecosystems, which have rich values in maintaining ecological balance, regional economy and human development. Wetlands can provide freshwater resources and food sources for human beings, purify the water environment and mitigate climate change. The grassland ecosystem has such ecological functions as windbreak, sand fixation, soil preservation, climate regulation, air purification, water conservation and so on, which are closely related to human survival and well-being. In recent years, climate change and human activities have caused a profound impact on the structure and function of wetland and grassland ecosystems, and the problems of decline in size and function have attracted extensive attention from researchers globally. However, there are still many uncertainties about the variety of wetland and grassland ecosystem composition, structure and dynamics, as well as how they respond and adapt to climate change and human activities.
Download or read book Key Determinants of Biodiversity Ecosystem Functioning and Restoration in Climate Change Sensitive Ecosystems written by Hui Zhang and published by Frontiers Media SA. This book was released on 2023-11-27 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human activities such as agriculture and mining have led to serious negative effects on biodiversity and important ecosystem services including biodiversity loss and climate change. Thus, it is important to quantify the key determinants of biodiversity, ecosystem functioning and ecological restoration of degraded plant communities in climate change sensitive ecosystems (i.e. subalpine and alpine meadow communities in Qinghai, tropical rainforests and tropical mountains). In this way, effective management, policy and methods can be developed to reduce the influence of climate change on these climate change sensitive ecosystems. The aforementioned human activities continue to destroy and degrade plant communities and ecosystem functioning. Climatic changes further exacerbate negative impacts and may trigger rapid loss of species, precipitate decline and changes in the flows of ecosystem goods and services. As the collective anthropogenic influence intensifies, some ecosystems may be more sensitive than others to these changes. Ecosystems that contribute greatly to human well-being through the delivery of biodiversity and ecosystem benefits should be the focus of particular concern. There are key knowledge gaps on the specific nature of anthropogenic impacts, species and ecosystem responses, and possible management and mitigation measures. Comprehensive documentation of these aspects from highly sensitive regions and ecosystems is urgently needed, particularly at fine scales, which is relevant for developing management and mitigation measures. Pathways such as ecological restoration can offset some of the impacts, but even quantifying the impacts of observed and anticipated changes is far from adequate and other mitigation measures must be considered.

Download or read book Advances in GIS and Remote Sensing the Landscape Pattern of Land Cover on Urban Climate and Urban Ecology written by Pedzisai Kowe and published by Frontiers Media SA. This book was released on 2023-11-24 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid urban expansion and associated land cover conversions in the last two decades call for an urgent need for developing advanced analytical and quantitative methods to manage the adverse impacts on urban ecology and climate. The lower landscape connectivity, higher land cover fragmentation and increase in higher surface temperatures in urban areas are largely a consequence of surface energy balance alteration triggered by the replacement of natural land covers like green spaces, wetlands with built areas, and impervious surfaces. These spatial-temporal variability changes have detrimental and significant impacts on the local and regional urban climate challenges that require both new Geospatial Analytic approaches and new sources of data and information. Emerging Geospatial technologies (Big Data, Cloud Computing, Google Earth Engines, Advanced Machine Learning Algorithms and Deep learning) offer great opportunities to acquire ubiquitous spatial data, continuous observations, and monitoring of the earth’s surface, detect the spatiotemporal patterns of changes in the landscape and urban climate and make predictions and scenarios for future urban ecology and surface temperature trends.

Download or read book Ocean Acidification written by National Research Council and published by National Academies Press. This book was released on 2010-09-14 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.
Download or read book Abrupt Climate Change written by National Research Council and published by National Academies Press. This book was released on 2002-04-23 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The climate record for the past 100,000 years clearly indicates that the climate system has undergone periodic-and often extreme-shifts, sometimes in as little as a decade or less. The causes of abrupt climate changes have not been clearly established, but the triggering of events is likely to be the result of multiple natural processes. Abrupt climate changes of the magnitude seen in the past would have far-reaching implications for human society and ecosystems, including major impacts on energy consumption and water supply demands. Could such a change happen again? Are human activities exacerbating the likelihood of abrupt climate change? What are the potential societal consequences of such a change? Abrupt Climate Change: Inevitable Surprises looks at the current scientific evidence and theoretical understanding to describe what is currently known about abrupt climate change, including patterns and magnitudes, mechanisms, and probability of occurrence. It identifies critical knowledge gaps concerning the potential for future abrupt changes, including those aspects of change most important to society and economies, and outlines a research strategy to close those gaps. Based on the best and most current research available, this book surveys the history of climate change and makes a series of specific recommendations for the future.

This book was released on 2000-09-08 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently, the Departments of Defense (DOD) and Commerce (DOC) acquire and operate separate polarorbiting environmental satellite systems that collect data needed for military and civil weather forecasting. The National Performance Review (NPR) and subsequent Presidential Decision Directive (PDD), directed the DOD (Air Force) and the DOC (National Oceanic and Atmospheric Administration, NOAA) to establish a converged national weather satellite program that would meet U.S. civil and national security requirements and fulfill international obligations. NASA's Earth Observing System (EOS), and potentially other NASA programs, were included in the converged program to provide new remote sensing and spacecraft technologies that could improve the operational capabilities of the converged system. The program that followed, called the National Polar-orbiting Operational Environmental Satellite System (NPOESS), combined the follow-on to the DOD's Defense Meteorological Satellite Program and the DOC's Polar-orbiting Operational Environmental Satellite (POES) program. The tri-agency Integrated Program Office (IPO) for NPOESS was subsequently established to manage the acquisition and operations of the converged satellite. Issues in the Integration of Research and Operational Satellite Systems for Climate Research analyzes issues related to the integration of EOS and NPOESS, especially as they affect research and monitoring activities related to Earth's climate and whether it is changing.
