    Technical Note: Why Methods Matter. A Guidance for Data-based Climate and Hydrological Change Assessments

    Year: 2016

    Collections: Short Communications

    Topics: Water, Climate, Agriculture, Sustainable Development, IWRM

    Authors: Unger-Shayesteh Katy, Gerlitz Lars, Vorogushyn Sergiy

    An important topic of the journal “Integrated Water Resources Management in Central Asia” will be the assessment of past and future changes in climate and water resources in Central Asia. This technical note aims at providing guidance for sound data-based assessment of changes to be published in this journal. The main requirements for achieving credible results are (1) the use of consistent data series, (2) the selection of appropriate change detection methods, and (3) the discussion of the results, their uncertainties and limitations. Using an example of trend analysis, it is exemplarily shown how inhomogeneities in a data series, the selection of start and end points, the applied methods, and temporal aggregation may affect the results of change studies.

    Management interventions to increase water use efficiency in the irrigation sector of Central Asia were introduced but a scientific control instrument is still missing - The online tool WUEMoCA provides relevant irrigation performance indicators in the Aral Sea Basin from satellite data in combination with additional sources - WUEMoCA-based analysis of water security and water use efficiency showed: o 11 out of 33 provinces in the Aral Sea Basin were below the critical level to supply crop water demands for more than 5 years in 2000-2018. o Irrigation water use efficiency is very low in general (55%-60%) and scientific data hints at missing or failing water management interventions in the Amu Darya and Zarafshan basins. - WUEMoCA can strategically supplement the ongoing digitization efforts of the countries in the water sector. - By utilizing WUEMoCA-like tools, Central Asian governments and water management bodies will have new platforms for steering and assessing current and future strategic interventions in regional water management.
