Report on Stakeholder Evaluation of Aquatic Resources. Deliverable 5.2 : Study Sites: Northern and Central Vietnam.
Nguyen Thi Dieu Phuong, Søren Lund and Gary Thomas Banta. Highland Aquatic Resources Conservation and Sustainable Development Project – Roskilde University, 2013.
Abstract: The present report on stakeholder evaluation of highland aquatic resources provides an overview of completed research activities undertaken within the HighARCS project on the value ascribed by users, local communities and stakeholders to functions, goods and services (including non-use values) derived from the aquatic resources in the Northern and Central of Vietnam. The perceived impact of factors such as environmental degradation, changing demand for goods and services and modified highland aquatic resources management practices on these values has also been assessed.
Social and ecological challenges of market-oriented shrimp farming in Vietnam.
Ngo Thi Phuong Lan. SpringerPlus, 2013, volume 2, number 1, p. 675.
Abstract: Vietnam is one of the largest shrimp exporters in the world. Since 2010, Vietnam has earned about two billion dollars annually through shrimp exports. As a fertile area of greatest potential for agricultural production in Vietnam, the Mekong Delta has been a major contributor to the country’s achievements, especially in the agricultural sector. During recent decades, trade liberation along with various policies in support of aquaculture has accelerated the development of shrimp production in the Delta. Based on an ethnographic study of shrimp farming in the Mekong Delta of Vietnam, I assert that along with great rewards arising from the expansion of shrimp farming areas, productivity, and export value, the shrimp industry has brought various environmental, economic and social challenges. Consequently, shrimp farming is a risky business and local inhabitants have relied on various strategies to cope with these challenges. Risk mitigation in shrimp production and labor migration are the two important strategies of local inhabitants for securing their livelihoods. Water pollution and poor quality post-larvae shrimp are direct consequences of market-oriented production. Free full text http://www.springerplus.com/content/2/1/675.
Community forests as heterotopia. The case of the Mu community forest – Ngoc Son – Ngo Luong Nature Reserve, Vietnam.
Nguyen Ngoc Quang, Danny Wildemeersch and Jan Masschelein. International Journal of Environmental Studies, 2013, volume 70, number 6, pp. 877-892.
Abstract: This paper examines issues of culture and power in regard to the Mu sacred forest, Vietnam, a community forest. The research uses Foucault?s notion of ?heterotopia? as a heuristic tool to interpret forest management. It appears that the Mu sacred forest can be understood as a space of ?self reflective construction?, but also a space that might dissolve, destabilize, interrupt and suspend power. The moment of power suspension frees people from their usual frames. They can escape to some extent from authority and repression. This suggests that sustainable forest management can be promoted through acceptance of local culture and that community forest can be a ?space of suspension and learning?. [T&F].
Making community forest management work in northern Vietnam by pioneering participatory action.
Khongsak Pinyopusarerk, Thi Thu Ha Tran and Van Dien Tran. Land Use Policy, 2014, volume 38, number 1, pp. 257-263.
Abstract: Transfer of land-use rights from the state to individual households and groups of households to encourage community forest management (CFM) and use of forest resources for livelihood improvement, has been in place in Vietnam since the 1990s. However, to date there has been no evidence of allocation to groups of households as community entities with joint ownership. This paper examines the success of processes tested in four villages in mountainous northern Vietnam to officially secure joint ownership of and exclusive rights to community forest land. After four years, implementation of CFM led to enhanced equality and distribution of benefits, and better protection of forest resources. Household income remained largely unchanged, in part because of loss of income from activities which were now illegal, but also because it was too early for benefits to flow from new forestry initiatives. Active participation of and between village communities in land-use planning and allocation, and a willingness to compromise, particularly on the position of land boundaries, were essential elements to ensuring equity in the distribution of benefits. Lack of enabling processes and experience in the implementation of government policies mean that further support for village communities is needed to fully realize the benefits from joint management of the allocated community forest.

Production Function of Planted Mangroves in Thanh Phu Nature Reserve, Mekong Delta, Vietnam.
Nguyen Thi Kim Cuc and Erik D. de Ruyter van Steveninck. Journal of Coastal Research, 2013 in press.
Abstract: Through assessment of forest structure, biomass of mangrove plantations in the Thanh Phu Nature Reserve, Mekong Delta, Vietnam was analyzed in correlation with diameter at breast height (DBH, i.e. at 1.3 m height). Study plots were set up in 7, 11–22, and 26-year-old planted Rhizophora apiculata Blume plantations. There is a significant inverse correlation between DBH and tree density (R2 = 0.73; p < 0.01). To derive an allometric relation to estimate aboveground biomass, 32 trees representing all ages were chosen randomly and harvested at ground level to examine allometric relations. We measured the fresh and dry weight of stems (WS), branches (WB), leaves (WL), and aboveground stilt roots (WR) in situ. Allometric relationships were satisfied best with DBH as an independent variable (R2 = 0.72, 0.89, 0.87, 0.98, and 0.97 for leaves, branches, stilt roots, stem, and total aboveground biomass, respectively; p < 0.001). The total aboveground biomass was estimated in the plantations to vary between 76 and 320 tons/ha. Of this, more than 50% of total aboveground biomass was represented by stems. The estimated biomass value of this study is consistent with that of other mangroves in the world. Total biomass of R. apiculata plantation in Thanh Phu Nature Reserve accounted for about 170,057 tons dry weight or 8056 tons C.

Farmland Loss and Poverty in Hanoi‘s Peri-Urban Areas, Vietnam: Evidence from Household Survey Data.
Farmland Loss and Poverty in Hanoi‘s Peri-Urban Areas, Vietnam: Evidence from Household Survey Data.
T. Q. Tuyen and V. Van Huong. Agris on-line Papers in Economics and Informatics, 2013, volume 5, number 4.
Abstract: Using a dataset from a 2010 field survey involving 477 households, this paper has contributed to the literature by providing the first econometric evidence for the impacts of farmland loss (due to urbanization and industrialization) on household poverty in Hanoi‘s peri-urban areas. Factors affecting poverty were examined using a logit regression model. Our econometric results indicate that the one and two-year effects of farmland loss on poverty are not statistically significant. These results, therefore, confirm that farmland loss has had no impact on poverty in the short-term. This study also found that factors contributing to poverty reduction include households‘ education, access to credit, ownership of productive assets and participation in nonfarm activities before farmland loss. We propose some policy implications that can help households escape poverty and improve their welfare. [Tuyen_Huong-2013.pdf].

Recent land subsidence caused by the rapid urban development in the Hanoi urban region (Vietnam) using ALOS InSAR data.
V. K. Dang, C. Doubre, C. Weber, F. Masson and N. Gourmelen. Natural Hazards and Earth System Sciences Discussions, 2013, volume 1, number 6, pp. 6155-6197.
Abstract: Since the 1990s the land subsidence due to the rapid urbanization has been considered a severely destructive hazard in the center of Hanoi City. Although previous studies and measurements have quantified the subsiding deformation in Hanoi center, no data exist for the newly established districts in the south and the west, where construction development has been most significant and where groundwater pumping has been very intensive over the last decade. With a multi-temporal InSAR approach, we quantify the spatial distribution of the land subsidence in the whole Hanoi urban region using ALOS images over the 2007-2011 period. The map of the mean subsidence velocity reveals that the northern bank of the Red River appears stable, whereas some areas in southern bank are subsiding with a mean vertical rate up to 68 mm yr-1, especially within the three new urban districts of Hoang Mai, Ha Dong and Hoai Duc. We interpret the spatial distribution of the surface deformation as the combination of the nature of the unsaturated layer, the lowering of groundwater in the aquifers due to pumping withdrawal capacity, the increase of built-up surfaces and the type of building foundation. The time evolution deduced from the InSAR time series is consistent with previous leveling data and shows that the lowering rate of the surface slightly decreases till 2008. Then, a seasonal variation suggests that the deformation became non-stationary, with upward and downward transient displacements related to the charge and discharge of the aquifer following the changes between rainy and dry seasons.
Cost, return analysis and constraints in livestock production and marketing in Hai Duong, Vietnam.
LE Thi Minh Chau, Philippe LEBAILLY and NGUYEN Tuan Son. Jahorina IV International Symposium “Agrosym 2013”, Bosnia and Herzegovina, October 3-6, 2013., 2013.
Abstract: The study, using the survey data from 145 livestock production households, showed that livestock contributed significant parts to the households’ income. Given a production unit, the high investment in inputs and the considerable experience in production and marketing created higher income for the livestock-based group than that for the non livestock-based group. However, the farmers perceived some constraints relating to both production and marketing. The result from the Garrett’s ranking technique presented the ranking position of constraints, respectively included the livestock disease, the limited credit access, the high and rapid increase in feed price, the high volatility of output price, and the insufficiency of market information and weak bargaining power.

Forages improve livelihoods of smallholder farmers with beef cattle in South Central Coastal Vietnam.
Nguyen Xuan Ba, Peter A. Lane, David Parsons, Nguyen Huu Van, Ho Le Phi Khanh, Jeff P. Corfield and Duong Tri Tuan. Tropical grasslands, 2013, volume 1, number 2.
Abstract: In South Central Coastal Vietnam, on-farm research and farmer experience demonstrated the benefits of growing improved forages as a means of improving the year-round quantity and quality of feed available for smallholder beef cattle production. In Binh Dinh, Phu Yen and Ninh Thuan provinces, 5 new forage species (Panicum maximum cv. TD58, Brachiaria hybrid cv. Mulato II, Pennisetum purpureum cv. VA06, Paspalum atratum cv. Terenos and Stylosanthes guianensis cv. CIAT 184) were evaluated for yield and crude protein concentration. There was no consistent yield difference between locations for the forage grasses, but in Binh Dinh province P. maximum TD58 produced the highest yield. The grasses were comparable in crude protein concentration. Stylo CIAT 184 produced much less forage than the grasses but had a much higher crude protein concentration. All species have potential use, depending on the circumstances and site factors such as fertility, drainage and availability of irrigation. This work was expanded to a total of 45 farmers to gain feedback on farmer experience in growing different forages. The percentage of farmers who “liked” the introduced forages was Mulato II, 92%; TD58, 85%; VA06, 82%; Paspalum, 46%; and Stylo, 36%. By far the most important early socio-economic impact of developing perennial forage plots close to households was an average 50% reduction in the amount of labor and time that farmers spend supplying cut-and-carry forage to their animals. In addition, the growing of forages can meaningfully reduce the grazing pressure on common grazing lands, thereby lowering the potential for environmental degradation.
