The policies are not as effective as anticipated for many reasons. Many farmers cannot access the credit support because of complicated and inconsistent procedures such as the requirement of submitting an invoice. The minimum local content requirement for machines is not realistic. To access the concession loans, enterprises have to sign contracts for production linkages, consumption of agricultural products and usage of agricultural mechanical services with co-operatives, households and individuals (Tran and Dinh, 2014a). However, there are some challenges to implementing and monitoring the programme because of the large number of farmer households - approximately 10 million. There are also difficulties with identifying whether the upland rice field is in planning area or not.
