Agriculture and Environmental Impact Quiz

Study Notes

Agriculture and Greenhouse Gases

Agriculture is the largest contributor to greenhouse gas emissions.
This is due to the lack of heavy industry in the agricultural sector.
Agriculture contributes to greenhouse gases in the form of carbon dioxide, methane, and nitrous oxide.

Water Quality and Eutrophication

Agricultural practices can negatively impact water quality through a process called eutrophication.
Run-off from fertilizers containing nitrates and phosphates can cause excessive algae growth, leading to algal blooms.
Algal blooms block sunlight, inhibiting photosynthesis and causing fish deaths.
Implementing a 5-meter buffer zone between fertilizer application areas and watercourses can reduce the impact of eutrophication by half.
Farmers should collect and prevent waste from dairy parlours, cattle yards, and pit washings from entering waterways.

Biodiversity and Agricultural Practices

Land drainage, pollution, and improper grazing practices are significant threats to biodiversity.
The shift from haymaking to silage production negatively impacts bird populations.
Corncrakes, which traditionally nest in tall grasses, suffer habitat loss due to silage making.
Hedgerows, which provide natural barriers and shelter for livestock, are crucial for biodiversity.
Promoting hedgerow growth enhances habitat for various species.

Organic Farming and Sustainability

Organic farming is gaining popularity as consumers become more conscious of food production methods.
Organic farming relies on biological controls, crop rotation, and eliminates the use of chemical fertilizers and pesticides.
Organic practices contribute to less pollution and healthier habitats compared to conventional farming.
