Tool risk reduction measures

100 RISK REDUCTION MEASURES

Please note:

This catalogue contains 100 measures that can contribute to the mitigation of heavy rain risks. These measures are very diverse: they range from structural to non-structural measures and from small, easy-to-implement solutions to comprehensive conceptual approaches.

The catalogue was compiled from existing catalogues from all RAINMAN partner countries as well as from knowledge and experiences made in the project without claiming universal coverage and without having expert knowledge in each of the covered business areas. Sources for further information and good practice examples are provided for a large number of the included measures.

Use the selection feature to find measures that are applicable in the field of action that you are dealing with or search for key words you are looking for.

Please consider that heavy rain risk reduction measures work best, when they are strategically applied and cleverly combined under consideration of the local conditions. Go back to RISK REDUCTION MEASURES for further guidance.

No- or low (conservation) tillage totally or largely foregoes the use of ploughs. Instead, tillage tools are used that do not turn the soil (e.g. cultivators, disc harrows) or disturb the structure of the soil while leaving crop residues (= mulch) near or on the surface of the soil. Strip cultivation or striptill is a variable tillage and sowing method mainly for row crops, which creates a 15 to 20 cm wide seedbed, leaving two-thirds of the field untilled. The idea behind these technologies is to create a stable soil texture that is not highly susceptible to soil sealing while maintaining or increasing infiltration capacity. The measure is very efficient for heavy rain risk reduction on farmland by increasing of soil water retention and decreasing runoff.

Fields of action Farmland
Additionally to flood risk reduction by slowing and storing surface runoff, these measures have medium or high possible benefits for the following biophysical impacts and ecosystem services: Reduce pollutant sources; Improve soils; Absorb and/or retain CO2; Increase soil water retention; Reduce erosion and/or sediment delivery; Climate change adaptation and mitigation; Groundwater/aquifer recharge; Filtration of pollutants; Biodiversity preservation
