Seminar by LenaTallaksen(University of Oslo):
Drought – Lessons learnt and future perspective
About the talk: Lena M. Tallaksen was awarded the 2024 Dooge medal (the International Hydrology Prize) of the International Association of Hydrological Sciences (IAHS), UNESCO and the World Meteorological Organization (WMO) at the end of last year. From IAHS: She received the prize “in recognition of her outstanding and remarkable contributions in taking to new frontiers the hydrological understanding of extreme weather events for the betterment of our communities”. The talk will build on her presentation at the prize ceremony in Brazil.
Abstract
In this presentation, I will highlight key lessons learned following a career within low flow and drought research. A period that coincides with an increasing awareness of drought as a natural hazard at the local, regional and continental scale. It is also a period when the influence of global change (human intervention and climate change) on the hydrological cycle, water resources and extremes, became prominent and the research focus shifted from more traditional hydrological analysis to the detection, attribution and projection of the global change signal on hydrology. When analysing drought and its wide range of impacts, it is important to distinguish between the different types of droughts, and when analysing changes and trends, it is important to distinguish between natural variability and changes due to climate change or human interventions. How drought is defined and perceived in different sectors and hydroclimatic regimes, influences the choice of methodology and how the results are interpreted and communicated. In this talk, I will reflect on the importance of drought terminology and an awareness of the diversity in drought behaviour in drought studies. These aspects will be illustrated with key examples from the literature and accompanied by recent advances in drought research.

About the seminar series
The talks in GeoHyd Lunch Seminar Series are offered by the Section for Geography and Hydrology (GeoHyd), Dept. of Geosciences, University of Oslo. The seminars are announced as lunch seminars so bring your lunch if you want to.
The seminars are open for everyone interested, and especially students are welcome.
