Question

scenario 3: in many grassland regions, farmers are facing a growing problem with soil erosion and nutrient loss. years of planting and harvesting crops have left the soil bare for much of the year, exposing it to strong winds and heavy rains that wash away the rich topsoil. without this top layer, the land becomes less fertile and harder for plants to grow in, leading to lower crop yields and more dust in the air. as the soil continues to degrade, it also loses the ability to hold water, making the land more vulnerable to drought. scientists and farmers are now looking for ways to protect and rebuild the soil so that the grassland can remain healthy and productive for future generations.

1. summarize the problem affecting this grassland in one sentence.
2. based on the lesson 4.3 notes, what sustainable farming practice might be helpful for this grassland? explain your answer to receive credit.

Explanation:

The problem in scenario 3 is soil erosion and nutrient loss due to crop - planting and harvesting, which makes the land less fertile, more vulnerable to drought, and causes dust in the air. Sustainable farming practices from Lesson 4.3 (though not specified here, common ones like crop rotation, cover - cropping, contour plowing) would help by protecting the soil, reducing erosion, and maintaining fertility.

Answer:

1. Soil erosion and nutrient loss from crop - planting/harvesting degrade the land, reducing fertility, increasing drought vulnerability, and causing dust.
2. Sustainable farming practices (e.g., crop rotation, cover - cropping) protect soil, reduce erosion, and maintain fertility for a healthy and productive grassland.
