Southerners have new jobs thanks to rising levels of seawater
Sea water rise and saline intrusion have damaged crops this year, but they have offered opportunities for farmers to breed shrimp on rice fields. According to the Ca Mau provincial Department of Agriculture and Rural Development, at first, when farmers began trying to breed shrimp, the yield was low, just 100-200 kilos per hectare. Now, as they have experience, the yield is 320-350 kilos per hectare. Meanwhile, the rice yield has also increased to 4-4.1 tons per hectare. Doan Van Day in Tan Hung commune of Cai Nuoc district said the rice-shrimp crop rotation is far better than pure rice growing, and farmers many times had crop failure because of early saline intrusion.
