Answer :
Final answer:
Two effective methods to reduce agricultural impact on the river ecosystem involve cutting petrochemical use and applying erosion control techniques.
Explanation:
Methods to Reduce Agriculture Impact on River Ecosystem:
- Reduce the use of petrochemicals: By minimizing the use of fossil fuel-based machinery, dependency on distant supply lines for fuel is reduced, thereby lessening the carbon footprint and global climate change impact.
- Implement physical and biological erosion control: Strategies like using cover crops, contour plowing, and grassed waterways help minimize soil erosion caused by wind, water flow, and other mechanical means, preserving soil quality for sustainable agriculture.
