Indirect Effects on Humans and Wildlife
SCCWRP researchers are developing a multiple lines of evidence (MLOE) approach (similar to that shown here) to evaluate the potential for indirect effects from contaminated sediments. The lines of evidence are expected to include: sediment contaminant concentration, bioavailability of sediment contaminants, and prey tissue contaminant concentration. ...

Direct or indirect? A difficult condition attached to ARD activities is that these should be direct in nature. ... for engaging in a particular activity would also help in determining how direct it is. Indirect effects includes climate change phenomenon like El Nio cycles, and carbon dioxide fertilisation (where higher ...

Alternative States: Can we trust simple models on impact by livestock in dry rangelands? Applied Vegetation Science. V 2, issue 2, pp261-268. His article attempts to make a comprehensive list of the direct and indirect effects of herbivorous grazing on dryland ecosystems. Various (non)-equilibrium state paradigms are examined, the conclusion serves to highlight the ...

Other Greenhouse gases - CO
Other Greenhouse gases - CO Other Indirect Greenhouse Gases - Carbon monoxide Carbon monoxide (CO) is only a very weak direct greenhouse gas, but has important indirect effects on global warming. Carbon monoxide reacts with hydroxyl (OH) radicals in the atmosphere, reducing their abundance. As OH radicals help to reduce the lifetimes of strong greenhouse gases, like methane, carbon monoxide ...

The Regional Impacts of Climate Change
CO2 concentration (which may have a beneficial effect on the growth of many crop types). Indirect effects will include potentially detrimental changes in diseases, pests, and weeds, the effects of which have not yet been quantified in most available studies. Evidence continues to ...

The Regional Impacts of Climate Change
Direct effects could include ecosystem shifts, sea- and river-ice loss, and permafrost thaw. Indirect effects could include feedbacks to the climate system such as further releases of greenhouse gases, changes in ocean circulation drivers, and increased temperature and higher precipitation with loss of ice, which ...

Books from the Earth Policy Institute
The indirect effects of the economy on the earth a century ago were minimal. This is no longer the case. Today the indirect costs of various goods and services may exceed the direct costs, the costs that determine the market price. When we buy a ...
