Analysis:
The man first walks northwards, then turns left twice. After the two left turns, he finds himself 1 km west of his starting point.

Given Information:
- Distance walked westward: 1 km
- Distance walked eastward: 2 km

Calculations:
Let's assume the distance walked northwards initially is x km.
After walking 1 km westward, the man is exactly 1 km west of his starting point, which means the northward distance and the southward distance cancel each other out. Therefore, the total northward distance is equal to the total southward distance.
So, total northward distance = total southward distance
x = 2 km
Hence, the man walked 2 km northwards initially.
Therefore, the correct answer is 2 km.
