There is increasing interest in the use of market-based instruments such as tenders and trading systems to address water quality issues. While the focus is typically on the improvements in resource allocation that are generated, these instruments also play an important role in addressing issues of asymmetric information. The use of water quality tenders to reveal the opportunity costs of changing agricultural practices can help policy makers to understand the potential costs of misallocating public resources and to design better ways of achieving water quality improvements. This role of water quality tenders to reveal opportunity costs is demonstrated by reporting four pilot applications to improve water quality into the Great Barrier Reef in Australia. The results demonstrate the potential for opportunity costs to vary substantially between agricultural producers, and across industries, catchments and pollutants. The results from these case studies indicate that the most cost-effective water quality improvements may be generated from the horticulture and dairy sectors. In contrast, the opportunity costs of reducing emissions from the cane and grazing industries appear to be higher.
Research highlights▶ Public funding has been provided to landholders in single shot, discriminative price auctions. The results reveal the cost of supplying better water quality outcomes in Great Barrier Reef catchments in Australia. ▶ Reduced sediment, nutrient and pesticide emissions in runoff from agriculture leads to better outcomes for the health of the Great Barrier Reef. ▶ Four water quality tender case studies are presented involving different agricultural industries in different regional areas. ▶ The results indicate that more cost effective emission reductions can be achieved from the diary and horticulture industries compared with those from the cattle grazing and sugarcane sectors.
