What are some ways Mesopotamia irrigated their fields ?

Canal construction.

Explanation:

Canal construction was the primary irrigation mechanism used in ancient Mesopotamia. The entire community participated in the development of these channels. Canals were built up to twenty meters wide, and they were connected to hundreds of smaller canals. In this way, the first forms of agriculture were created. With the canal's construction, the inhabitants of ancient Mesopotamia controlled irrigation, but they also brought water to areas that did not have enough water.

of what agreement it does not show

it is a part of john locke's natural rights popular during the age of enlightenment that people had inalienable rights to life, liberty and property. this was reflected by thomas jefferson in his declaration of independence as rights to life,liberty and the pursuit of happiness.

another line in the declaration of independence is that people have certain rights just because they are human. humans are capable of obeying the three natural rights john locke mentioned making them governable by these laws and therefore entitled to these rights as well.
