This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Soil and Water Assessment Tool (SWAT) and HYDRUS were used to assess the impact of climate change on the hydrologic cycle (streamflow, surface runoff, groundwater recharge, evapotranspiration, and irrigation water use) and agricultural pollutant runoff (sediment, nitrate, phosphorus, chlorpyrifos, and diazinon) in the Sacramento and San Joaquin River watersheds in California's Central Valley. Five separate studies were constructed. For the first three studies, hydrological responses were modeled in the San Joaquin River watershed using variations of atmospheric CO2 (550 and 970 ppm), temperature (+1.1 and +6.4°C), and precipitation (0%, ±10%, and ±20%) based on Intergovernmental Panel on Climate Change projections. The fourth study used a calibration and an uncertainty analysis technique for the calibration of the Sacramento River watershed. This study confirmed that SWAT was able to capture the large amount of uncertainty within the Sacramento River watershed and successfully simulate streamflow, sediment, nitrate, chlorpyrifos and diazinon loads. The final study used a novel stochastic climate change analysis technique to bracket the 95% confidence interval of potential climate changes. For all studies, increases in precipitation generally changed the hydrological cycle and agricultural runoff proportionally, where increases in precipitation resulted in increases in surface runoff and thus agricultural runoff and vice-versa. Also, for all studies, increasing temperature caused a temporal shift in plant growth patterns and redistributed evapotranspiration and irrigation water demand earlier in the year. Increasing atmospheric CO2 resulted in watershed-wide decreases in evapotranspiration, therefore increasing water yield and streamflow while concurrently decreasing irrigation water use. This research improves the understanding between climate change and hydrology and agricultural pollutant runoff within the Central Valley of California. Theses climate change analyses may be used by water resource managers to evaluate the potential effects of climate change.

Book excerpt: Between 1958 and 2008, the CO2 concentration in the atmosphere increased from 316 to 385 ppm. Continued increases in CO2 concentration will significantly affect long-term climate change, including variations in agricultural yields. Focusing on this critical issue, Elevated Carbon Dioxide: Impacts on Soil and Plant Water Relations presents research

This book was released on 2005-08-31 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of rising levels of greenhouse gases—and the global consequences for crops! Carbon dioxide is a major greenhouse gas that causes global warming and directly impacts every aspect of plant life and indirectly impacts animal and human life. Atmospheric carbon dioxide levels have risen dramatically over the past century, and though this could mean opportunities for better growth and increased yield of certain crops, other factors like weather extremes and changes to plant physiology may mitigate the positive effects. Ecological Responses and Adaptations of Crops to Rising Atmospheric Carbon Dioxide comprehensively analyzes every aspect of crop responses to increasing carbon dioxide as well as their productional significance for the world. Changes in the growth rate and yield of crops are explored, with attention given to the consequences of coming weather changes on production and the expected economic impact. Ecological Responses and Adaptations of Crops to Rising Atmospheric Carbon Dioxide takes the data gleaned from careful research to provide an in-depth vision of the impact of carbon dioxide on global temperatures, plant physiology, and the ecological and economic future of our world. Respected authorities thoroughly discuss the research detailing the complete range of issues from plant growth under increased carbon dioxide levels to the impact of rising air temperatures to the evolving ecophysiological responses within various crops. Extensive references provide opportunities for further research while detailed tables and graphs clearly illustrate data. Ecological Responses and Adaptations of Crops to Rising Atmospheric Carbon Dioxide explores the effects of carbon dioxide enrichment on: plants, crops, and vegetation—is it beneficial? growth, yield, and photosynthetic responses in rice the photosynthetic capacity and productivity of rice under field conditions—and the role of nitrogen fertilization forage and grain nitrogen content potato crops crop responses including interaction with temperature the growth of maize different agricultural systems around the world—such as central and southeastern Europe, northern climates, Sudan, citrus-growing regions, and others the production ecophysiology of Hungarian green pepper and much more! The impending changes in our world make Ecological Responses and Adaptations of Crops to Rising Atmospheric Carbon Dioxide a valuable text for educators and postgraduate students in the field of plant ecology and crop production and an essential resource for researchers in the fields of plant ecology, ecophysiology, agricultural crop production, and environmental sciences.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Except in Northern latitudes, the annual daily maximum temperature increases at a faster pace than the mean temperature, which is reinforced by vegetation feedbacks in Europe but reduced in North America. This work highlights the key role of vegetation in influencing future terrestrial hydrologic responses. Accurate representation of the response to higher atmospheric carbon dioxide concentration levels, and of the coupling between the carbon and water cycles are therefore critical to forecasting seasonal climate, water cycle dynamics and to enhance the accuracy of extreme event prediction under future climates in various regions of the globe.
