In the expanses of the province of Kamau (Vietnam), recently, unique farms have been operating with increased environmental friendliness. It is a question of open spaces on which farm employees alternately grow rice or shrimp.

It is noteworthy that the process of creating both one and the second product takes place on a single platform.

Many local farmers have long decided to abandon chemical fertilizers, growth stimulants and pesticides in their daily agricultural and fish farming practices. And to this day they have managed to establish a successful and productive scheme.

So, in the wet seasons, rice grows in the fields, which is generously watered by rains. When drought occurs, farmers plant young shrimp in the marshy soil. From one hectare at the end of the season, employees of these farms collect over seven tons of rice and about fifty tons of shrimp.

The total area of ​​territories engaged in ecological farming in the open spaces of Kamau is one hundred twenty hectares. For clarity, it should be added that in the specified province the territory of the fields on which only rice grows is eighty-five thousand hectares.

Fields of fish farms exclusively for shrimp cultivation are two hundred eighty-one hectares. And the area of ​​fields with alternate cultivation of rice and shrimp is equal to forty thousand hectares. That's just not every farm that specializes in such alternate production has switched to an environmentally friendly type of activity.

It should be noted that it is Kamau that supplies over forty percent of shrimp to the Vietnamese market. In weight equivalent, the indicator is one hundred twenty thousand tons of product per year.
