Reducing Nonpoint Source Pollution
76 Vegetated buff ers are a well-studied and widely used agricultural management practice for reducing nonpointsource pollution. A wealth of literature provides experimental data on their mitigation effi cacy. Th is paper aggregated many of these results and performed a meta-analysis to quantify the relationships between pollutant removal effi cacy and buff er width, buff er slope, soil type, a...
متن کاملNonpoint Source Pollution
A Total Maximum Daily Load (TMDL) program has been initiated in the North Bosque River Watershed in Texas, USA, where point and nonpoint sources of pollution are of a concern. The Soil and Water Assessment Tool (SWAT), which had been validated for flow and sediment and nutrient transport, was applied to quantify the effects of Best Management Practices (BMPs) related to dairy manure management ...
متن کاملNonpoint Source Pollution and Optimal Regulation
This paper analyzes effects of nonpoint source pollution on regulation optimal contracts in asymmetric information situation. We consider a continuum of agents (to formalize major characteristic of nonpoint source pollution) which pollute another agent (affected agent). We distinguish different forms of externalities and examine if it is always necessary to modify optimal contract of each respo...
متن کاملAgroforestry buffers for nonpoint source pollution reductions from agricultural watersheds.
Despite increased attention and demand for the adoption of agroforestry practices throughout the world, rigorous long-term scientific studies confirming environmental benefits from the use of agroforestry practices are limited. The objective was to examine nonpoint-source pollution (NPSP) reduction as influenced by agroforestry buffers in watersheds under grazing and row crop management. The gr...
متن کاملNutrient Retention by Multipond Systems: Mechanisms for the Control of Nonpoint Source Pollution
The processes of the multipond system in an experimental agricultural watershed located in southeastern China were studied during a 2-yr period (1994-1995), with the purpose of the research being the reduction of nonpoint nutrient pollution at its sources. The mechanisms studied included water storage capacity, sedimentation, denitrification, and removal of nutrients by the harvest of macrophyt...
