Changes in the technical and scale efficiency of rice production activities in the Mekong delta, Vietnam.
 Changes in the technical and scale efficiency of rice production activities in the Mekong delta, Vietnam. 
Diep Thanh Tung.

Agricultural and Food Economics 2013, volume 1, number 16. 

Abstract: I used bootstrapping data envelopment analysis (DEA) to measure changes in technical and scale efficiency in rice production in the Mekong delta region, Vietnam. The data include sample production sets from 1998 and bi-annual updates from 2002 to 2010. Technical efficiency changed significantly over this period, showing an upward trend. On the other hand, increasing return to scale is dominant trend, which reflects the need to increase the rice production scale generally and expand land use particularly. Meanwhile, the government has been trying to prevent land consolidation activities and restrict production scales using quotas and agricultural land use duration rules.

Impacts of changes in mangrove forest management practices on forest accessibility and livelihood: A case study in mangrove-shrimp farming system in Ca Mau Province, Mekong Delta, Vietnam. 
Tran Thi Phung Ha, Han van Dijk and Leontine Visser. Land Use Policy, 2014, volume 36, pp. 89-101.

Abstract: This paper documents how the implementation of forest tenure policy affects the decision-making of farmers in mangrove-shrimp farming systems with regard to their access to and management of mangrove forest in Ca Mau, Mekong Delta, which is the largest remaining mangrove forest in Vietnam. Policies on land allocation, land tenure and use-rights are important since they potentially promote sustainable mangrove-shrimp management. Forest management policy in Vietnam has been changed to promote equality of benefit sharing among stakeholders and devolved State forest management to the household level. However, to what extent its implementation can stimulate both mangrove conservation and livelihood improvement is still being debated. We use access and its social mechanisms to investigate how State Forest Companies (FC) and farmers can benefit from mangrove exploitation. The study was conducted from September 2008 to August 2010 using both qualitative and quantitative methods and using a participatory approach. After group discussions and in-depth interviews with a wide range of stakeholders, we interviewed 86 households in four communities using structured questionnaires. Results show the imbalance in access to finance, markets, and differences in authority between the two actors, farmers and FC. The discussion focuses on the possibilities of “win–win” outcomes, i.e. land tenure regimes promoting the devolution of sustainable forest management to farm households to balance benefits of both mangrove conservation and livelihood improvement.

Systems of cattle production in South Central Coastal Vietnam.


Systems of cattle production in South Central Coastal Vietnam. 
D Parsons, P A Lane, L D Ngoan, N X Ba, D T Tuan, N H Van, D V Dung and L D Phung. Livestock Research for Rural Development, 2013, volume 25, number 2. 

Abstract: The objective of this study was to describe cattle production systems in South central coastal Vietnam including: farming resources, herd structure, feed resources, feed and feeding management, and constraints to cattle production. The study site, representative of the agro-ecological characteristics of the sandy zone in the South central coast, included Phu Cat, Tuy An, and Phuoc Nam districts selected from Binh Dinh, Phu Yen, and Ninh Thuan provinces, respectively. Secondary and primary data on cattle production systems were collected using both quantitative and qualitative research methods. Participatory meetings at the commune level were organised to collect qualitative information. In addition, 180 households were interviewed by using a set of questions. — Results showed that surveyed households in Ninh Thuan had advantages in raising cattle compared with Binh Dinh and Phu Yen in terms of labour and land area; however they were also more limited by lower rainfall. Households in Ninh Thuan had twice the number of cattle, sheep, and goats than those of the other two provinces; however  households in Binh Dinh and Phu Yen had greater numbers of pigs and poultry than farmers in Ninh Thuan, suggesting different income generating strategies. The method of raising cattle of surveyed households in Ninh Thuan was more extensive than in Binh Dinh and Phu Yen, evident by the scale of crossbred cattle, feeding systems, cattle management, and feed resources. Planting grass, storing agricultural by-products, supplying concentrate, cutting naturalized grass, and restricting the amount of cattle were methods suggested by surveyed householders to solve the lack of feed issue. Capital was believed by producers to be the most important factors that influenced cattle production (69% of farmers). Other important limitations to production included lack of feed and disease.
