Empirical Assessment Of Climate Change Impacts On Agriculture In Samarkand Region, Sh.B. Babakholov
Irrigation and Melioration
Agricultural production is highly sensitive to climate factors like other endogenous factors, and the expected climate change projections may have a negative impact on the efficiency and income of agricultural producers. Therefore, this study aims to analyze the impact of changes in climatic factors (average air temperature and precipitation) on the technical efficiency of cotton growing farmers as its determinants in Samarkand region. Empirical analyzes were performed on the cases of 1141 cotton-growing farms using panel-based Time-Invariant Inefficiency model. According to the results of the analysis, cotton farms in the region have an average technical efficiency of 76%, which in …

Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث
In this research, the impact of some climate change effects on the olive tree was studied. Specifically, the research investigated the impact of the lack of water and drought on the physiology of olive trees using stable carbon isotopic (Delta13C) and C/N ratios. Four olive cultivars including Souri, Roomi, Improved-Nabali, and Nasouhi, planted in three geographical areas with different rainfall patterns were used. These locations are Yatta/Hebron area (dry and low rainfall area with less than 300 mm/year), Jab’a/Jerusalem area (semi-dry and medium rainfall zone), in addition to the Kufer Ra’e/Jenin area (area of high rainfall, higher than 550 mm/year). …

Irrigation and Melioration
Agricultural production is highly vulnerable to climate shocks and predicted climate consequences may pose severe challenges to the resilience of Uzbek agricultural system, especially in terms of food security and income stability of rural producers. In this context, present study proposed to assess the impact of climate factors, such particular changes in mean temperature and rainfalls on total output of wheat-cultivating farmers in Samarkand region. By considering irrigation source and heterogeneous geography of the region, farmers engaged in wheat production were analyzed in two: upstream and downstream zones using Fixed effect panel approach. The empirical findings of study revealed that, …
Determination And Assessment Of The Spatio-Temporal Changing Dynamics In The Groundwater Level And Mineralization In Irrigated Areas Under Climate Change (As An Example Of Syrdarya Province), S. Khasanov, S. Adilov, R. Kulmatov
Determination And Assessment Of The Spatio-Temporal Changing Dynamics In The Groundwater Level And Mineralization In Irrigated Areas Under Climate Change (As An Example Of Syrdarya Province), S. Khasanov, S. Adilov, R. Kulmatov
Irrigation and Melioration
In the irrigated lands of the Aral Sea Basin, salinization processes are taking place as a result of rising groundwater levels and increasing its mineralization due to the unsustainable use of water and land resources. This, in turn, leads to the withdrawing of arable land and a decrease in crop yields. This is especially the case in the irrigated areas of the lower reaches of the Amudarya and Syrdarya rivers, located in Uzbekistan, southern Kazakhstan, and Turkmenistan. This research was aimed to learn and evaluate the long-term changing behavior of groundwater level and mineralization in the irrigated areas of the …

Patterns For Populus Spp. Stand Biomass In Gradients Of Winter Temperature And Precipitation Of Eurasia, Vladimir Andreevich Usoltev, Baozhang Chen, Seyed Omid Reza Shobairi, Ivan Stepanovich Tsepordey, Viktor Petrovich Chasovskikh, Shoaib Ahmad Anees
Aspen Bibliography
Based on a generated database of 413 sample plots, with definitions of stand biomass of the genus Populus spp. in Eurasia, from France to Japan and southern China, statistically significant changes in the structure of forest stand biomass were found, with shifts in winter temperatures and average annual precipitation. When analyzing the reaction of the structure of the biomass of the genus Populus to temperature and precipitation in their transcontinental gradients, a clearly expressed positive relationship of all components of the biomass with the temperature in January is visible. Their relationship with precipitation is less clear; in warm climate zones, …
Projected Surface Water For Fruit And Vegetable Irrigation Under A Changing Climate In The Us, Marty Matlock, Greg Thoma, Kieu Ngoc Le, Eric Cummings, Zach Morgan, Andrew Shaw
Projected Surface Water For Fruit And Vegetable Irrigation Under A Changing Climate In The Us, Marty Matlock, Greg Thoma, Kieu Ngoc Le, Eric Cummings, Zach Morgan, Andrew Shaw
Water Systems
Increasing greenhouse gas concentrations in the atmosphere, resulting in climate impacts, are raising concerns over the hydrologic cycle and its effects upon agricultural productivity. If rainfall patterns change, meeting an increased demand for fruits and vegetables will pose a challenge for domestic production regions in the United States (U.S.). Information on potential water supply scarcity in the current production regions provides decision makers with critical information for risk mitigation for future production. We used a hydrologic balance-based model of historic and future water availability to evaluate risk of available irrigation water to support major fruit and vegetable production the US. …
What’S Going To Happen To My Pancakes? The Impacts Of Climate Change Upon Blueberries And Sugar Maple, Ashley Kayser
What’S Going To Happen To My Pancakes? The Impacts Of Climate Change Upon Blueberries And Sugar Maple, Ashley Kayser
Honors College
The United Nations believes that the foremost challenge of the future will be climate change. Because of human use of fossil fuels, greenhouse gases have been released into the atmosphere at unsustainable rates, which have resulted in an altered climate that will impact weather patterns around the globe. There have already been measurable shifts in precipitation and temperature in many regions; in the state of Maine the general trend has been toward higher temperatures and increased precipitation. This is resulting in impacts to agriculture throughout the state. Blueberries and sugar maple are two culturally and economically valuable crops which will …

Bridging The Food Gap: Founding And Sustaining A Food Recovery Network Chapter At Wku, Elaine Losekamp
Bridging The Food Gap: Founding And Sustaining A Food Recovery Network Chapter At Wku, Elaine Losekamp
Mahurin Honors College Capstone Experience/Thesis Projects
Food waste is a pervasive global issue with many environmental and social repercussions. While about one-third of all food produced for human consumption goes to waste, many people in the United States and the world are affected by food insecurity. Food recovery, the process of rescuing edible food that would otherwise go to waste and delivering to hungry people, is an effective solution for both food waste and food insecurity. The author of this capstone created a food recovery program at Western Kentucky University (WKU) in January 2019 and has grown the program’s scope and impact since that time. This …

Solar Dimming Decreased Maize Yield Potential On The North China Plain, Qingfeng Meng, Baohua Liu, Haishun Yang, Xinping Chen
Department of Agronomy and Horticulture: Faculty Publications
Solar dimming has been increasing in rapidly developing regions (China and India) and threatening food security. Although previous studies have summarized the ef- fects of climate change-associated increases in temperature on agriculture, few have examined the effects due to solar dimming. Here, we analyzed the effects of solar dimming on maize on the North China Plain (NCP). It is reported that solar dimming intensified and maize yield potential decreased since the 1960s. The total decrease in solar radiation for the whole maize growing season of this period was 17%, and solar dimming explained 87% of the decrease in yield potential. …
Physiological Ecology Of Overwintering And Cold-Adapted Arthropods, Leslie Jean Potts
Physiological Ecology Of Overwintering And Cold-Adapted Arthropods, Leslie Jean Potts
Theses and Dissertations--Entomology
Given their abundance and diversity, arthropods are an excellent system to investigate biological responses to winter. Winter conditions are being majorly impacted by climate change, and therefore understanding the overwintering biology of arthropods is critical for predicting ecological responses to climate change. In Chapters 2 and 3, I investigate the winter biology of a winter-active wolf spider. I show that winter-active spiders can take advantage of periodic prey resources and grown in the winter, which may allow them to get a jumpstart on spring reproduction. I also investigate spiders’ ability to track changes in their environment by quantifying low temperature …
