After several meetings in Vu Thu district, surveys have started in Vu Tien, Vu Doai, Viet Thuan, Duy Nhat and Viet Hung commune; our 15 junior experts and students can now face the real situation of the Vietnamese countryside and test their questionnaires. Despite the field constraints, E3P teams and local officers have worked together in the better way to identify farms and agronomical situation of interest. 3 weeks will be then dedicated to this specific district where pig fattening, maize and rice are well developped despite urban concentration.
