| Research Abstract |
This study aims to understand the development of manure policies in the Netherlands and to investigate the economic consequences and environmental effects. Although manure production is decreasing and mineral balances are getting better since the introduction of Mineral Accounting System(MINAS), mineral losses are still high and the further reduction is necessary in order to attain the target. Nitrate concentration declines in the shallow groundwater in farms, while it still exceeds the standard of 50mg/l in sandy soil areas. It takes longer time for nitrate concentration in deeper groundwater.
Next, economic measures for Dutch manure problem are analyzed such as manure/pig/poultry production rights and MINAS levies. The system of manure production rights allows the transfer of rights, but trades were sporadic because of many restrictions, policy uncertainty, and ample initial distribution of rights. This scheme is not a system of tradeable pollution permits, rather a system of production quotas, resulting in failing to minimize manure reduction costs.
MINAS levies were set to sufficiently high level in order to comply the mineral loss standards. That is why the levy did not lead to efficient outcome. It is the mineral accounting approach that contributed to the decline in nitrogen and phosphorus losses. MINAS worked well in the dairy sector, but not in pig and poultry sector where there is less land.
In Japan, almost livestock farms are only prohibited to open storing and unlined lagoon. There is no application standard. Mineral balances should be considered also in Japan.
