The instrument that would be most suitable and appropriate for managing ecosystem and resources at the South Esk basin are assessed here. The need for an instrument is understood as a most basic requirement for the South Esk. The South Esk basin needs to be reformed. The issues of the South Esk basin are that it has to be maintained in a healthy way for purposes of drinking, swimming, recreational activities and more. When these are taken for granted, and then the water sources are not sustainable over the long run.
Some of the major impacts are because of the population living in the area, the industries, and other agricultural land uses. Some of the major population centres in the area that contribute to impact are St Mary’s, the Perth area and the Avoca. The form of discharge that is observed is anywhere from 30-189 liters in sewage water from treatment plants. However, the water is satisfactorily passed into sewage treatment lagoons (Tasmania Department of Primary Industries, Water and Environment, 2005). The second major impact is industrial effluents, and the forestry activities associated with some industries. In terms of agricultural use, the water is made use of in irrigation, and is pumped up the stream for cropping purposes when stock watering is required.
The state policies on water quality management are very clear about why it is necessary to enhance the water. Water quality management has been issued to make use of the public input as well. In the case of the south Esk River in particular, it has been observed that many catchment environmental issues have arisen. Erosion and soil losses are some of the foremost issues here, accompanied by losses in the form of phosphorous that happens during flood events. In the context of preservation, the habitat quality with respect to flora and fauna needs special mention as well.
Similarly, some of the other issues that have to be taken into consideration when applying a market instrument is how the clearing of the flood plains are causing different levels of flood peaks. This leads to summer water flow reduction challenging agriculture and other water dependent activities. The forestry activities are also seen to result in erosion and other forms of deterioration. In addition, there are metal contaminations noticed from some of the existing waterways that will have to be developed as soon as possible (Tasmania Department of Primary Industries, Water and Environment, 2005). Its development however could also add to additional stress issues.
