Abstract
  • Due to the immanent common property problem of water, non-point-pollution is the common feature of many inland waters and the eutrophic levels are alarmingly high. drinking water and other services are negatively affected by high eutrophic levels fisheries. Concerning causes of pollution, agriculture, subject to overuse of fertilizer and pesticides, is regarded as the main polluter. Environmental regulations on farm practices, such as animal waste and fertilizer application, seek to minimize shocks imposed by eutrophying substances. Since many waters already show high concentrations of these substances, even cleaning is needed. In the dynamic context of eutrophication, which results from multiple polluters and is accumulated over time, damage to water quality depends on stocks and flows of pollutants. The paper presents a model that counts for limitation of inflows and attributed levels of farm activity to pollution. The paper applies a combination of dynamic control and political economy models, optimized by a manager of a common property, a clean lake, a river or, more generally, an interconnected watershed. It seeks to achieve an agreed level of cleanness or eutrophic levels of water on behalf of a community. A political economy model depicts the bargaining process for the establishment of an objective function of the community. The manager is a partial manager, not a benevolent dictator, but has statutory power to regulate fertilizer application on lake shores and alleviate eutrophication with nutrients. Benefits are purified waters that benefit all members, including fishermen. As institutions, the approach investigates the tragedy of the commons and statutory regulations. Financial innovations for compensation are also possible.
