Question
Contrast between tree breaks and check dams.
Answer in Brief
Solution
Contrast between tree breaks and check dams:
- Tree breaks:
- Purpose: Tree breaks, also known as windbreaks, are rows of trees or shrubs planted to limit wind speed, so minimising soil erosion and crop damage.
- Function: The primary purpose is to protect soil and crops from wind erosion.
- Location: Typically planted in open areas or farmlands where wind erosion is a problem.
- Effect on Ecosystem: Creating green corridors improves air quality, provides habitat for creatures, and increases biodiversity.
- Impact on Agriculture: Protect crops against wind damage, prevent soil drying, and increase agricultural yields in windy areas.
- Check dams:
- Purpose: Small barriers are placed across streams or water channels to restrict water flow, reduce runoff, and avoid soil erosion by allowing water to soak into the earth.
- Function: The emphasis is on managing water flow, preventing erosion, and recharging groundwater.
- Location: Constructed in streams, gullies, or small watercourses, particularly in locations with high water runoff.
- Effect on Ecosystem: Increase water supply, reduce flood risk, and establish miniature aquatic ecosystems in the immediate region.
- Impact on Agriculture: Increase water retention for irrigation, raise groundwater levels, and protect valuable soil from erosion.
