Session 15b – “Coping with Drought” Part II & III

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 II: Drought impacts, responses and vulnerability

Droughts impact socioeconomic and ecological systems worldwide. Drought impacts, however, depend on differing site specific drought hazard characteristics and vulnerabilities.  Effective drought risk management must be based on an understanding of historical drought impacts and ad-hoc responses. Thus information and data about the specific impacts of droughts on different sectors as e.g. agriculture, energy and domestic water supply are absent for most of the regions worldwide. Also National, Regional and local policies as well as governance practices involved in response actions play an important role and might be displayed in such data.  For example: to assess the relationship between agricultural losses and drought events, we need long term information about yields and land use changes or longer time series of high resolution land cover images; to assess impacts of droughts on the hydropower sector we need at least monthly long term basin scale hydropower generation data; to understand the implications of a drought for domestic water supply we need to know the institutional response and additional costs involved in water supply; etc.
In this part of the drought session we address the impact/response data collection and how we can establish a relationship between hazard and impact data. Institutional and policy related aspects are looked at to understand their role in responding and data generation related to drought.
Your expertise and experiences from case studies worldwide will be valuable contributions to this analysis. Please also fill in the related questionnaire: www.soscisurvey.de/drought-panta-rhei/

Keywords: droughts in the Anthropocene, drought responses, drought impacts, drought risk and adaptation, impact related indicators, impact data and remote sensing, drought policies, water governance

Key questions:

  • Which data do you use to assess drought impacts?
  • How do you detect responses to droughts?
  • How do you define and assess vulnerability and do you related impacts to vulnerability?
  • Which institutions are responsible to respond to droughts and how do they respond?
  • Which policies are relevant for drought risk management?
  • How can drought impacts be assessed for different sectors (qualitatively/quantitatively)?
  • How do individuals respond to droughts?
  • Which drought impact indicators would you highlight for your region? How can we use satellite based data to assess drought impacts (e.g. Actual evapotranspiration from irrigated agriculture)

Part III: Drought risk management

Drought risk can be considered as a combination of drought hazards and vulnerability: drought hazard +drought vulnerability =drought risk (UN-ISDR, 2009; IPCC SREX, 2011). After looking at the hazard and the vulnerability –which can be understood by looking at historical impacts –, we want to see how such information is implemented in drought risk management (DRM). Furthermore we look at DRM best and worst practices and underlying methods.

This part of the drought session aims at presenting, discussing and grouping drought risk management approaches.

Keywords: Drought risk, drought risk management, Drought in the Anthropocene, Drought responses, Drought alert and forecasting

Key questions:

  • How do you implement drought risk management and based on which data and concepts?
  • Is your DRM effective?
  • Which institutions are involved in DRM?
  • How would you design drought risk management in your region and based on what information?
