Jim Salinger's Work

Chances are that if a newspaper or television report needs a comment on weather,especially climate change,it will be Jim you hear to see.As a climate researcher at university and later in the former New Zealand Meteorological Service,Jim has long been involved in researching and monitoring past and current climate trends.He works as a principal scientist with NIWA,The National Institute of Water and Atmospheric Research.There he prepares climate updates and leads research projects on New Zealand's climate change.In 1975 as he began his PhD studies at Victoria University.Jim was looking through data.He worked out his part of the world was warming up.This was odd because the suggestion from scientists in the Northern Hemisphere was that the world was moving towards an ice age.

Soil Erosion

Soil Erosion 

Introduction:

Soil erosion is a process that happens naturally.How fast it happens depends on how steep a place is, the weather, plants or lack of them and what’s below the soil. Changes that people make to the land can also make it erode more quickly.  As the soil erodes, it finds its way into our rivers and harbours.

One of Northland's biggest water pollutants is silt or, more precisely, fine clay particles. Slow-flowing rivers, like the Northern Wairoa and the Hātea River above the Whangārei Town Basin, are among the most polluted by silt.

Our monitoring shows that water from the Northern Wairoa sometimes contains more than a kilogram of clay particles per cubic metre of water.

Experiment:1.Soil Erosion

We put a water on a sand to make a soil erosion.

Experiment:2.Effects of Vegetation

The wind and water erosion turn the hills into a flat land.

Conclusion:What Should New Zealand Do To Reduce Soil Erosion 

A range of measures have been used to control or prevent erosion on New Zealand’s farmland. Some were adopted from other countries such as the USA, some were learnt by trial and error, and others developed from research.

Biological control is usually cheaper, but more risky, than mechanical methods.

Trees Trees reduce the rate of erosion by

protecting the soil from the impact of rain
transpiring large amounts of water, which counteracts very wet soil
binding soil to sloping land with their roots.
Spaced planting

Trees, commonly poplars, are planted strategically on slip-prone hill country such as the area around Taihape. Thousands have also been planted throughout the North Island hill country.
