Why is rainwater harvesting important in sustainable farming practices? (Choose 2)
1. Water conservation: Rainwater harvesting allows farmers to collect and store rainwater, reducing the dependence on groundwater or surface water sources. This helps to conserve water resources, especially in dry or drought-prone regions.
2. Soil health: The use of rainwater for irrigation can help improve soil health by providing a natural, chemical-free source of water. Rainwater is typically free of salts and other contaminants often found in groundwater or surface water, which can have negative impacts on soil fertility and crop growth. By using rainwater, farmers can maintain healthier soils and more sustainable farming practices.
