Find the explanation below.
Explanation:
The Yellow River, known as the second-longest river in China and located in its northern part is a beautiful natural endowment cherished by the people in the region but which has been affected by the activities of man. Today, the river is plagued with flooding. Research has shown that man's activities dating to thousands of years ago proved the construction of embankments meant to control the overflow of water from the river. This effort was to have future negative effects.
These levees caused the accumulation of sediments which eventually resulted in flooding. It was also the expansion and intensification of agricultural activities by man that warranted the construction of the levees on this river.

The Neolithic revolution was the first agricultural revolution. It was a gradual change from nomadic hunting and gathering communities and bands to agriculture and settlement. This period is described as a "revolution" because it changed the way of life of communities which made the change. It occurred in different prehistoric human societies at different times. Many societies changed 9–7 thousand years ago.
The term refers to the general time period over which these developments took place. It also applies to the changes which took place: the adoption of early farming techniques, crop cultivation, and the domestication of animals. The Neolithic Revolution is important for developments in social organization and technology.
The Neolithic revolution led to living in permanent or semi-permanent settlements. Because of this fewer people led a nomadic lifestyle. To be able to know who the crops grown belonged to, the concept of land ownership was developed. The natural environment was changed, population densities grew, and people ate more vegetable and cereal foods in their diet. Hierarchies developed in society. Grain was stored, and could be traded. Surplus production from good crop yields helped societies survive bad years.
