Damage to fragile environments: farming in East Anglia

Causes and effects of the damage

Causes: changes in farming methods	Effects
Mechanisation	Soil compaction by heavy machinery reduces infiltration and increases surface runoff and soil erosion
Large-scale agribusinesses	Large scale farms or agribusinesses are more efficient Agribusinesses are intensive with monocropping involving high inputs of machinery, fertilisers and pesticides Removal of hedgerows and woodland, drainage of wetlands to create large field sizes Increase in soil erosion Loss of biodiversity Not sustainable
Increased field size	Equipment can be used more efficently Removal of woodland and hedgerows Wetlands drained Loss of habitats and biodiversity Increase in pests Increase in use of pesticides Increase in soil erosion Not sustainable
Increased use of chemical fertilisers	Improves farm yields Causes eutrophication of water courses Can breakup the soil structure and lead to soil erosion Nitrates pollute the water supply, and can be harmful to human health - e.g. blue baby syndrome Not sustainable
Increased use of chemical pesticides	Loss of biodiversity Not sustainable
Monocropping	More efficient use of machinery Exhausts the soil nutrients and destroys the soil structure Requires chemical fertilisers in increasing quantities and is not sustainable
Burning of straw	Declining air quality
