Vietnam; Rotating Shrimp with Rice in the Mekong Delta

 
Under a blazing sun in Dong Thap Province, Vo Thi Nhieu and her husband are absorbed in reinforcing their levees to prepare their newly harvested rice field for the upcoming shrimp crop.  The work is harder than last year because they decided to expand the shrimp farm by half a hectare this year.  “We have adopted the practice of shrimp-rice farming for the last three years.  We used to cultivate only a one-hectare field.  The profits we made from it encouraged us to expand this year,” said Nhieu.
 
“Last year my family earned $3,300 from one hectare, with $2,500 of that coming from shrimp.  It has helped us lead a much easier life.  Besides buying appliances necessary for a modern family, like a television, refrigerator, video and even a computer, we can now afford to send our four children to high school and university.  Three years ago my family grew only rice, earning $335 or $392 per year.  My husband and I had to do other jobs, including hawking during the rest of the year to support the family.”
 
There has also been an unexpected windfall from farming shrimp.  Nhieu explains: “In the past, before we took up shrimp farming, we often had to use 30 sacks of fertilizers for our one hectare paddy.  But we now need only 12 because the field has become more fertile, thanks to the waste produced by the shrimp and other organic residue.  We have cut farming costs by more than half.”
 
Last year, seven provinces in the delta, including Tra Vinh, Bac Lieu, Soc Trang, Ca Mau, Ben Tre, Kien Giang and Long An adopted shrimp-rice farming on a combined 120,000 hectares, 23 percent of the Mekong Delta’s total arable land.
 
Dr. Do Minh Nhut, director of the Kien Giang Agricultural and Fishing Centre, said shrimp-rice farming is now the first option in his province, with farmers adopting the system on 70,000 hectares, the largest area in the region.  It is expected to expand to around 100,000 hectares in the coming years, he said.
