  • Climate change and water resources: Case study of Eastern Monsoon Region of China

    • Authors: Duan, Q.; Xia, J.;  Advisor: -;  Participants: - (2017)

  • This paper addresses the impact of climate change on the water cycle and resource changes in the Eastern Monsoon Region of China (EMRC). It also represents a summary of the achievements made by the National Key Basic Research and Development Program (2010CB428400), where the major research focuses are detection and attribution, extreme floods and droughts, and adaptation of water resources management. Therefore, climate change is making a significant impact and will be a risk to the EMRC, which covers almost all of the eight major river basins, such as the Yangtze River, Yellow River, Huaihe River, Haihe River, and Pearl River, and to the South-to-North Water Diversion Project (middle line). To ensure water security, it is urgently necessary to take adaptive countermeasures and redu...

  • Anatomy of the 2016 drought in the Northeastern United States: Implications for agriculture and water resources in humid climates

    • Authors: Wolfe, D.W.; Sweet, S.K.;  Advisor: -;  Participants: - (2017)

  • Here we focus on the impacts of the drought on farmers in New York State (NY), an economically important agricultural state in the Northeast. We found that in several regions across NY 2015-16 winter snowfall, and 2016 growing season precipitation and streamflows were near or below the 10th percentile of the previous 60 years; and 2016 air temperatures were near or above the 90th percentile of the previous 60 years. Model estimates suggest NY state-wide crop irrigation water use could increase by 3–8 times in dry years compared to average growing seasons, increasing seasonal usage by millions of cubic meters. This highlights the potential for significant increases in water withdrawals in NY, with implications for water resources, particularly as the climate changes.

  • Application of synthetic scenarios to address water resource concerns: A management-guided case study from the Upper Colorado River Basin

    • Authors: Pederson, G.T.; McAfee, S.A.;  Advisor: -;  Participants: - (2017)

  • In this management-guided study, we use a very large suite of synthetic climate scenarios in a statistical modeling framework to simultaneously evaluate how (1) average temperature and precipitation changes, (2) initial basin conditions, and (3) temporal characteristics of the input climate data influence water-year flow in the Upper Colorado River. The results here suggest that existing studies may underestimate the degree of uncertainty in future streamflow, particularly under moderate temperature and precipitation changes. These results suggest that simple testing, like the analyses presented in this paper, may be helpful in understanding differences between existing studies or in identifying specific conditions for physically based mechanistic modeling. Both options could reduce...

  • What do New Yorkers Think about Impacts and Adaptation to Heat Waves? An Evaluation Tool to Incorporate Perception of Low-Income Groups into Heat Wave Adaptation Scenarios in New York City

    • Authors: Matmir, S.;  Advisor: -;  Participants: - (2017)

  • Low-income residents are among the most vulnerable groups to climate change in urban areas, particularly regarding heat stress. However, their perceptions about heat and the impacts they face go often undocumented, and are seldom considered in decision-making processes delivering adaptation. This paper presents a robust tool to allow the integration of perception, concerns and impacts of different income groups in urban adaptation planning and governance, using the City of New York as a case study. Employing online interviews—a solid method to reach poorer households—and Fuzzy Cognitive Mapping, we compare impacts and adaptation perception to heat and simulate adaptation scenarios. Results reveal that lower income groups are more concerned about impacts of heat waves than middle- an...

  • Impacts of climate change on agricultural water resources and adaptation on the North China Plain

    • Authors: Hu, S.; Mo, X.;  Advisor: -;  Participants: - (2017)

  • Climate change is having a considerable impact on the availability of water resources for agricultural production on the North China Plain (NCP). Global climate model (GCM) ensemble projections predict that by the 2050s, the increased crop water demand and intensified ET resulting from global warming will reduce water resources surplus (Precipitation–ET) about 4%–24% and increase significantly the irrigation water demand in crop growth periods. This study assesses possible mitigation and adaptation measures for enabling agricultural sustainability. It is revealed that reducing the sowing area of winter wheat (3.0%–15.9%) in water-limited basins, together with improvement in crop water-use efficiency would effectively mitigate water shortages and intensify the resilience of agricultu...
