Session 15a – “Coping with Drought” Part I

A growing water demand for food, energy and domestic water supply is often accompanied by increasing drought frequency and duration in many regions worldwide. Droughts are slowly evolving and complex disasters which are often poorly understood in the context of their regional climatic, hydrological and human environment. Hence the individual components leading to increased drought risk (hazard + vulnerability = risk) need to be assessed by quantifying triggers such as climate, catchment related drought propagation and human activities as well as past drought impacts on different sectors. To achieve this, we need to select site appropriate methods, information sources and tools.

For establishing short and long term drought management strategies we depend on a profound understanding about site specific drought risks and need to derive suitable indicators to be monitored at an adequate resolution both spatially and temporally.

This session aims at presenting and discussing concepts, instruments and data which can support drought management in data scarce regions. To structure the content of the numerous contributions, we devided the session theme into three subtopics:

The drought session covers three major topics which will be discussed during poster presentations (How to create a research poster-Guidelines):

  • Drought hazard related data and their utilization across the scales
  • Assessment of drought impacts and vulnerability
  • Drought risk Management

During three poster sessions we will address guiding questions to be discussed for each case study/poster.

From 17:30 onwards, our findings will be synthesized in a Podium discussion with drought experts (e.g. Justin Sheffield and Koen Verbist)

Part I: Drought hazard related data and information and their application in drought assessment across the scales

Keywords: Drought hazard related data, large scale drought monitoring, remote sensing and satellite based climate data, climate data resolution and related applications,  hydrological modelling, drought indicators and indices

Key questions:

  • Which large scale and remote sensing data are suitable to be used for drought assessment in data scarce regions?
  • What are the best and worst drought assessment practices for the specific case studies?
  • Which are the most suitable drought indices for which scale and climate?
  • How are real time satellite climate products used in drought monitoring, which and where?
  • How can we forecast meteorological and hydrological droughts and which variables need to be monitored at which scale?
  • How do real time PDO and ENSO related data feed into drought monitoring, forecasting and alert at the local scale?
  • To which extent should we calibrate hydrological models with satellite based climate products to obtain low flow simulations?
