Preparedness
Pre-emptive provisioning : Emergency
provisions for hydrological extremes that
can be initiated quickly for effective
management of water scarcity or periods of
fl ooding
Drought provision in Water Code
provides for institutional response
for drought management through a
presidential decree according to
technical parameters of Resolution
39 (1984). Informal institutional
responses intra and inter JdV are
invoked.
Policy frameworks for longer term flood
management complemented by canton
and local directives and management
plans for pro-active and reactive flood
response. No rules on scarcity
management.
Flexibility : Proportional Reduction of water
rights; prioritisation of certain uses.
No prioritisation of uses in 'normal'
periods; Tourno allows for
proportional reduction of water
rights within the separate sections
of the basin; DGA prioritises
domestic water, then irrigation
during decreed drought periods;
flexible reduction in rights
distribution according to % of flow.
Priorities for set periods in canton legal
framework; domestic water is
prioritised during scarcity situations.
Integration
Environmental Protection : Provisions for the
protection of aquatic ecosystems, including
both quality and quantity provisions.
Water code differentiates between
surface and ground waters; drought
declarations allow provisional rights
for surface- and groundwater and
remove limits of ecological flows.
WPA provides for quality and quantity
protection of waterways and aquatic
ecosystems; environmental protection
responsibility of Canton.
