Annotation of project:The ongoing climate change poses major challenges for the border region of Lower Austria and the
South Moravian Region, especially in the Dyje river basin and neighboring regions. The water balance
of this important and shared river catchment is already under strain, and as the dry years of 2015,
2017 and 2018 have shown, despite a robust water management system, the region has experienced
massive economic damage caused by drought, particularly in agriculture, but also in forestry. The
agricultural drought, which in 2018 in particular also almost immediately turned into a hydrological
drought, has shown to the public administration, farmers and water managers how complicated it is

to meet the water resource demands of the different sectors during an emergency situation. Under
these circumstances one of the principal rivers of the regions providing many valuable ecosystem
services in the regional river catchments itself has been compromised. Moreover, projections of
future climate change show that a similar situation is more likely to recur in the next few decades
than at any time in the past two centuries. For this reason, there is a need to exploit opportunities for
interdisciplinary and transboundary cooperation and to increase the resilience of the whole region in
respect to increasing climatic water balance deficits. This project has been initiated by the Lower
Austrian and South Moravian Chambers of Agriculture with the strategic cooperation of the Strategic
Partners of the Government of Lower Austria, the South Moravian Region and the Morava River Basin
Authority. The project has three main objectives: a) In cooperation with the two agrarian chambers
and academic institutions, compile a catalogue of measures and examples of good practice aimed at
specific and water-resource enhancing landscape management within the study area;
b) Propose and quantify feasible and farmer-implementable measures and their proper mix to
increase their resilience to drought and assess their impact on water resources in the study
catchments;
c) Propose and examine the feasibility of innovative and hitherto unconsidered measures such as
feasible water retention or water harvesting options to better manage existing water resources and
possible ways to enhance these resources in the region.
The present project will make use of the outputs of two prior projects addressing the actual target
region, namely the Interreg CZ-AT project "Impacts of climate change on the Dyje river basin" and the
TAČR project "Adapt-Dyje - Development of a tool for identification of the main risks of water
resources management in the Dyje river basin and methodology for their systemic solution under the
conditions of a changing climate". These projects developed a system tool in the form of a digital
twin of the Dyje river basin. However, specific measures such as the role of windbreaks, strip
cultivation, increasing the number of retention measures (re-activating historical ponds, water
harvesting through small-scale dams, rewetting of swamps etc.) or optimizing field crop
management, mulching and cultivation methods were not and could not be assessed because of the
lack of involvement of farmers from both sides of the border. Thus, the key players responsible for
about 2/3 of the landscape-evapotranspiration of our target region, i.e. farmers, have so far not been
involved in the formulation of measures that are feasible from their point of view. Similarly, the
potential hidden in the strengthening of water management systems and their interconnections has
not yet been comprehensively and substantively assessed for the entire border region. So far only
measures to optimize water reserves and resources have been considered on the respective side of
the border. While the measures resulting from the implementation of the first two objectives will be
immediately implementable, the output of the third objective will be available as a basis for strategic
discussions and cooperation between the public administrations of the two regions. The outputs of
the project will be both specific methodological procedures and tools for decision-support of single
or combined retention measures/water-saving options developed for farmers, training of target
stakeholders (e.g. farmers and companies, advisers) by the two agrarian chambers, and the outputs
of comprehensive basin analyses that will combine the benefits of the measures in the area with the
quantification of the potential benefits of the measures to strengthen the water management
infrastructure.
