Name two areas in north India where soil conservation is required.
Show Hint
Solution and Explanation
Himachal Pradesh is a mountainous state that faces severe soil erosion due to its steep terrain and heavy rainfall during the monsoon season. Soil conservation techniques such as terracing and afforestation are needed to reduce erosion and preserve soil fertility. The region's agriculture is dependent on the fertile soil, making soil conservation efforts vital for sustaining crop production and reducing landslides.
Step 2: Uttarakhand.
Uttarakhand, known for its hilly terrain and rich biodiversity, is another region in north India where soil conservation is required. The deforestation and overgrazing in the state have caused significant soil erosion. Moreover, heavy rains during the monsoon further contribute to the soil loss. To prevent this, methods such as contour ploughing, terracing, and afforestation are crucial to stabilize the soil and improve its water retention capacity.

- Object-Oriented Programming
- Write a program to accept a two-dimensional integer array of order \( 4 \times 5 \) as input from the user. Check if it is a Sparse Matrix or not. A matrix is considered to be a sparse, if the total number of zero elements is greater than the total number of non-zero elements. Print appropriate messages.
