Large explosive volcanic eruptions are expected to cause a range of impacts on primary production. Volcanic products such as pyroclastic flows, lahars and tephra fall can all cause significant impacts on soils, vegetation, animals, water supplies and people. During large explosive eruptions, farms and rural communities many tens to even hundreds of kilometres from the erupting volcano may be impacted, sometimes significantly. Effects can range from being beneficial (for example, by enriching trace elements in soils and pasture) through to extremely severe, for example if farmland has to be abandoned for the foreseeable future.
