Explanation:

A chinampa is an ancient Mesoamerican method of agriculture and territorial expansion that, through a species of rafts covered with soil, served to cultivate flowers and vegetables, as well as to expand the territory on the surface of lakes and lagoons of the Valley of Mexico; making Mexico-Tenochtitlan a floating city. They used them for agriculture and gain ground in the lake waters.

It is a raft, frame made with trunks and rods, sometimes of considerable size, on which is deposited properly selected topsoil with biodegradable materials such as grass, litter, husks of different fruits and vegetables, etc. In the chinampa a willow was planted so that its roots grew from the water to the mainland on the banks of lagoons and streams, and after the willow grew, they sowed different crops which they later harvested.

It is a technique initiated in the times of the Teotihuacan culture, although its maximum development was achieved in the sixteenth century. By 1519, this technique, for example, occupied almost all of Lake Xochimilco, and its combination with other techniques such as irrigation by canals and the construction of terraces, made it possible to sustain a very dense population.
