Producers in British Columbia have implemented peer review to minimize the effects of manure on water quality. In the prairies, the sharing of information on best management practices for enhanced water quality has been facilitated through Green Plan . While water management challenges are being addressed, further work is required as a more complete understanding of this challenge evolves. Minimize the negative effects of the agriculture and agri-food sector on water quality and increase water use efficiency. These gases are known as greenhouse gases because they trap heat in the atmosphere, thereby contributing to global warming or climate change.
Atmospheric change can affect agriculture.
Certain atmospheric pollutants linked to incomplete combustion of fossil fuels are known to cause damage to agricultural crops. Ground level ozone derived from oxidant smog is particularly harmful, for example, to white beans, potatoes and maple trees. In the long run, atmospheric change contributes to climatic variations which could ultimately affect cropping patterns. Agriculture contributes to atmospheric change in various ways. Agricultural machinery and grain drying and heating systems consume fossil fuels and release greenhouse gases and other pollutants.
