Climate change is expected to exacerbate soil loss and present challenges to the future
management of erosion-prone land. It is estimated that extreme storm events resulting in
flooding and slips are likely to occur somewhere in Taranaki about once every five to six
years. In coming years, the region is expected to experience more frequent and intense
heavy rainfall events, increasing both the frequency and

exceed 200 kg/ha/year.
Note: Council expectation is that all consents issued will require an exclusive discharge to land and
full storage. Dual discharges may be allowed, if the dairy farm is in a high rainfall area and provision
of adequate storage is impractical. The discharge of treated farm dairy effluent to surface water may
be authorised as a contingency, when land
moderate temperatures and regular rainfall, but when the rainfall is heavy it can
cause flooding and landslips. In periods of low rainfall, the region can experience droughts. In some parts
of the region, and at certain times of the year, storms and tornadoes are a reasonably frequent occurrence.
Coastal erosion
Coastal erosion is the retreat of the shoreline caused by water currents, waves, and wind. It is a natural
process that can be influenced by human activity. The Taranaki coastline
