Agricultural beneficial management practices (BMPs) are popular strategies for mitigating non-point sources of pollution. There are economic costs for BMP placement on agricultural lands mainly because it affects profit margins of farm operations. Given the cost implication and biophysical heterogeneity of farm lands, 8 the spatial targeting of BMP placement is consequential to their cost-effec...

The effects of climate change on future water availability and water quality are not well understood, making the development of watershed management plans difficult for decision-makers. Agricultural best management practices (BMPs) are commonly implemented to mitigate non-point source (NPS) pollution, but future effectiveness is unknown due to climate change. To address these problems, the foll...

The effort to manage diffuse pollution at the catchment scale is an ongoing challenge that needs to take into account trade-offs between environmental and economic objectives. Best Management Practices (BMPs) are gaining ground as a means to address the problem, but their application (and impact) is highly dependant on the characteristics of the crops and of the land in which they are to be app...

The Australian Government's Coastal Catchment Initiative (CCI) seeks to achieve targeted reductions in nutrient pollution to key coastal water quality hotspots, reducing algal blooms and fish kills. Under the CCI a Water Quality Improvement Plan (WQIP) is being prepared for targeted estuaries (Swan-Canning, near Perth, and the Vasse-Geographe, 140 km south of Perth) to address nutrient pollutio...

A questionnaire survey was conducted among farmers in the Xiangxi River Basin to investigate local livestock situation and farmers’ understanding of attitude towards pollution. The results showed that lacked environmental awareness few poultry pollution treatment measures had been implemented. However, once understood would greatly influence their lives interests, they act prevent Agricultural ...

Soil and water are fundamental precious resources for agriculture. In Atlantic Canada (AC), intensive agricultural production systems have led to detrimental environmental effects such as soil erosion the contamination of receiving waters, posing significant threats resilience sustainability agro-ecosystem. Although many beneficial management practices (BMPs) been developed, they all their shor...

Climate change will ultimately result in higher surface temperature and more variable precipitation, negatively affecting agricultural productivity. To sustain the production face of climate change, adaptive management or best practices (BMPs) are needed. The currently practiced BMPs include crop rotation, early planting, conservation tillage, cover crops, effective fertilizer use, so on. This ...

A key principle of agricultural best management practices (BMPs) is to improve water quality by reducing agricultural-sourced nutrients and associated eutrophication. Long-term (1998–2016) lake summer trophic state index (TSI) trends an watershed with were assessed. Structural BMPs included vegetative buffers, conservation tillage, reserve, a constructed wetland, sediment retention pond. TSI Se...

Beneficial Management Practices (BMPs) are important measures for reducing agricultural non-point source (NPS) pollution. However, selection of BMPs for placement in a watershed requires optimizing available resources to maximize possible water quality benefits. Due to its iterative nature, the optimization typically takes a long time to achieve the BMP trade-off results which is not desirable ...

Transport of phosphorus (P) from agricultural fields to water bodies deteriorates water quality and causes eutrophication. To reduce P losses and optimize P use efficiency by crops, better knowledge is needed of P turnover in soil and the efficiency of best management practices (BMPs). In this review, we examined these issues using results from 10 Swedish long-term soil fertility trials and var...
