Measures, tools and instruments (shortly measures) are possible management solutions for issues outlined in topics. Sometimes a combination of methods is needed to deal with an issue.  

The most measures are not mutually exclusive, on contrary they are reinforcing or synergistic. The fact that issues often do not come individually makes possible interventions even more complex. Nevertheless, good knowledge of ingredients (individual measures) certainly helps in making an appropriate combination.      

Measures can be about supply, that is securing current supply or increasing it. Other measures target demand for water, in order to decrease it or at least stabilise it. Regarding the groundwater quality, many measures on groundwater protection come in a form of regulations. Regulations are elaborated from a groundwater law and/or similar policy documents which determine groundwater governance at national and international level. Basically any management measures required stakeholders’ participation, at various levels and in various forms.
