Investments in protection against natural hazards
The figures reflect the Confederation's financial commitment to the prevention of natural hazards which is a task shared by the Confederation and the cantons. The federal authorities support the development of hazard documentation (hazard maps), the construction of protective structures (torrent, avalanche and rockfall barriers), the maintenance of protective forests and preparation of intervention measures. This also includes tasks involving the improvement of the warning and alerting of natural hazards (OWARNA). The total payment authorisations reflect only 1/3 of total expenditure by the federal government and the cantons on investment in protection against natural hazards.
In 2016, a total of CHF 226 million was spent on protection against natural hazards, the majority of which was invested in protective structures built in accordance with the provisions of the Federal Act on Hydraulic Engineering. This sum covers the requirement demonstrated for the cantons, what is viewed as a positive development. The guarantee credits are defined every four years in accordance with the new system of financial equalisation and division of tasks between the Confederation and the cantons. The payment authorisations are released in autumn for the following year.
International comparison is not possible because the legal frameworks are very different.
The figures are recorded by the FOEN through a survey of the cantonal budgetary data as part of the ongoing financial and project planning in the cantons and then corroborated. Based on this, the federal government calculates the payment authorisation for flood protection.
The federal government contributes about 1/3 of the total cost of projects.
