but a note of caution is important when considering the discussion here as the potential impacts on water quality from growing agricultural feedstocks for bioenergy production have not been fully evaluated national research council a oecd since many of the known adverse impacts on water quality from bioenergy production are due to the type of feedstock cultivated there is potential to mitigate these impacts through the adoption of conservation practices and systems usepa changes in climate and climate variability that affect the profitability of agriculture will in turn lead to changes in locations of crop and livestock production and technologies and management practices used to produce individual crops and livestock abler etal
