首先讲，另外一个原因，人口增长导致聚簇

Population growth is considered a particularly influential push.

1每个地方平均人多了，所以自然的culmination就是 crowded pueblos

After several generations of population growth, people packed the landscape in densities so high that communal pueblos may have been a necessary outcome. Around Sand Canyon, for example, populations grew from 5–12 people per square kilometer in the tenth century to as many as 30–50 by the 1200s. As densities increased, domestic architecture became larger, culminating in crowded pueblos.

2人口增长，需要相应的土地的need

Some scholars expand on this idea by emphasizing a corresponding need for arable land to feed growing numbers of people: construction of small dams, reservoirs, terraces, and field houses indicates that farmers were intensifying their efforts during the 1200s.

Evidence of intensifying agriculture in the 1200s indicates a need to feed a larger population and so extends the argument that a growing population was the cause of the move to pueblos.
