Riparian areas are critical interfaces between aquatic and terrestrial ecosystems. Protecting and enhancing them by implementing streamside management zones (SMZs) is an essential practice of sustainable forestry. SMZs provide ecological functions including protection against non-point source pollution, promotion of water infiltration, contribution of beneficial nutrients and coarse woody debri...

A physically based, spatially-distributed water quality model is being developed to simulate spatial and temporal distributions of material transport in the Great Lakes Watersheds of the U.S. Multiple databases of meteorology, land use, topography, hydrography, soils, agricultural statistics, and water quality were used to estimate nonpoint source loading potential in the study watersheds. Anim...

This paper considers a multi-task, principal-agent problem where risk-averse farmers possessing private information have two tasks, pollution control and corn production, but only direct incentive for corn production. Using a highly tractable reformulation of the standard uncertain production model, a general method for solving the associated constrained Paretian problem is developed and analyz...

Time series studies have suggested that air pollution can negatively impact health. These studies have typically focused on the total mass of fine particulate matter air pollution or the individual chemical constituents that contribute to it, and not source-specific contributions to air pollution. Source-specific contribution estimates are useful from a regulatory standpoint by allowing regulat...

Introduction Green finance plays a crucial role in driving sustainable development and has the potential to effectively reduce pollution emissions, thereby positively impacting environment. However, agricultural sector, China, unlike developed countries, primarily relies on small-peasant economy, green financial system is not well-developed. As result, specific emission reduction effects mechan...

The agricultural non-point source (NPS) pollution caused by non-irrigated farming, such as heavy metals, nitrogen and phosphorus, has posed an extreme threat to the security of product quality watershed ecology. Thus, it is urgent sort out latest research progress future development trend effectively guide scientific technological updates in this field. This study integrates relevant literature...

Nitrogen dioxide (NO2) is noxious, phototoxic and causes eutrophication. NO2 is one of the major precursors of ground level ozone pollution. Emission rates and emission concentrations of various pollutants from stationary sources of power plant emissions are calculated using Emission Inventory methodologies. Ground level concentrations of Nitrogen oxide (NOx) pollution are predicted by Gaussian...
