  • 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.

  • Temporal variation of pesticide mixtures in rivers of three agricultural watersheds during a major drought in the Western Cape, South Africa

    • Authors: Curchod, L.;  Advisor: -;  Participants: Oltramare, C.; Junghans, M.; Stamm, C.; Dalvie, M.A.; Röösli, M.; Fuhrimann, S. (2020)

  • Our study substantially widens the view on pesticide pollution in surface water compared to previous studies in Sub-Saharan Africa by targeting more than 200 pesticides using passive sampling systems. This broad assessment revealed the presence of 53 compounds, some of them in high concentrations, indicating possible adverse effects on biota and the quality of the ecosystem. Whether the observed concentration levels in the year 2017 were exceptional due to the lowest ever recorded rainfall and river discharge needs to be tested with additional data to better understand how pesticide pollution levels manifest under average rainfall and river discharge conditions.
