http://hueuni.edu.vn/csdlkhoahoc/index.php/nhakhoahoc/chitiet/861
This paper is an endeavor of the authors to examnine impacts of the intensive aquaculture on the groundwater at Vinh An Commune, Phu Vang District, Thua Thien Hue Province. Results showed that groundwater level in the study area varies from 0m to 4m above sea level in the dry season. Amount of the groundwater use for shrimp farming on the dune in one year is equivalent to 0.4 times (in 2012) to 4.8 times (in 2010) of that for the life water of residents in Vinh An Commune. As a result of measuring the groundwater level and testing the water quality in Vinh An Commune, this paper pointed out a possibility that the shrimp farming on the dune has caused the lowering of groundwater level and has affects on the quality of groundwater. The change of the coastline at Vinh An Commune by comparing the topographic map issued in 1970 and 2002 showed that the shoreline has retreated 40-100m in width during the 32 years and the saltwater intrusion into the groundwater near the coast in 2010 was caused by the coastal erosion and a fall in the groundwater level in recent years.
Key words: groundwater, intensive aquaculture, saltwater intrusion, sea level rise, coastal erosion.

This research is carried out in Huong Phong commune, lagoon area in Thua Thien Hue province with three main objectives: (1) improve household’s income and minimize the environment pollution, (2) determine suitable mushroom seedlings for the locality and (3) find the potentials to develop mushroom production activity in the lagoon area. Results showed that income from mushroom production was contributing 20-60% of total family income. Some households have high income from mushroom production such as Mr. Dau (33 million VND), Mr. Nam (19 million VND) and Mr. Kinh (16 million VND). The main mushroom season begins from April to September every year. The amount of mushroom can be consumed easily in local markets. The average of annual price is 55.000 VND per kilogram. In comparison with rice cultivation, mushroom production only requires a small portion of land and costs less for the investment yet brings higher income. After harvesting mushroom, 90% of participating households use wasted rice straws as fertilizer for vegetables in their garden. The results of this experiment show that mushroom seedling originated from Ho Chi Minh city contributes higher productivity than those from Hue city. Through the survey’s results related to mushroom cultivation from six communes bordering with Huong Phong Commune, currently two households only in one commune (Huong Vinh) out of six cultivate mushroom. In the remaining five communes (Phu Mau, Phu Thanh, Quang Thanh, Hai Duong and Thuan An) do not have any households doing this activity. Therefore, cultivating mushroom in household scales has the potentials and can be developed in the communes located in the lagoon area.

Nitrogen fertilization increases disease severity to rice blast fungus by affecting fungal pathogenicity but does not dampen plant defense
thuy, nguyen thi thu
BALLINI, Elsa
NOTTÉGHEM, Jean-Loup NOTTÉGHEM
MOREL, Jean-Benoit
Nitrogen-Induced Susceptibility (NIS) to plant diseases is a widespread phenomenon. In the case of rice blast disease, despite its agronomical importance, the molecular and cellular events underlying this phenomenon called “Koe-Imochi” are poorly understood. In this work, we set an experimental system in which nitrogen supply strongly affects rice blast susceptibility whereas it is only slightly perturbing plant growth. We show that fungal growth is affected before and after penetration in the plant but that the final penetration rate is not affected; thus a change in penetration is not responsible for increased susceptibility. In contrast, increased fungal growth late during infection of the plant is associated with enhanced lesion number and size. Differences in total nitrogen amount and defense gene expression before infection are unlikely to be responsible for the observed increase in penetration. After penetration, small changes in plant growth, but not modifications of the transcriptional regulation of defense genes, could be responsible for nitrogen-induced susceptibility. On the other hand, the fungus seems to perceive small differences in nitrogen amount after penetration and this may explain enhanced growth under high nitrogen regime. Indeed, exogenous treatment with some free amino acids after inoculation mimicked Nitrogen-Induced Susceptibility, further arguing that this phenomenon is mostly due to a trophic relation between the plant and the fungus. This experimental system also revealed that nitrogen-induced susceptibility to rice blast is dependent on the plant genetic background.

LOCAL FOREST GOVERNANCE AND PAYMENT FOR FOREST ENVIRONMENTAL SERVICES IN LAM DONG PROVINCE, VIETNAM
Thắng, Trần Nam
http://hueuni.edu.vn/csdlkhoahoc/index.php/nhakhoahoc/chitiet/991
Quế, Hoàng Thị Hồng
In order to evaluate the local governance of forest resources in Lam Dong in the Payment for Forest Environmental Service program, we interviewed, held group discussions with local people in the 2 communes Bao Thuan in Di Linh District and Da Chais in Lac Duong district, Lam Dong Province. We found that local people are, to some extend, different in their participation in forest governance. There are several related stakeholders that are directly involved in the local forest governance system, including forest owners (Protected are, special use forest, forest management board, State forest enterprises); forest protection department (local forest rangers); Commune People’s Committee and local communities. There are differences in the participation of those related stakeholders due to their rights and responsibilities in forest protection and management. We found that local people have not really participated in the local forest governance process. They are quite passive in the whole contracting process. The current benefit sharing mechanism does not really attract the participation and contribution from related stakeholders. The study suggests that, it is needed to revise the benefit sharing mechanism in order to attract the active participation of all related stakeholder especially local people for a sustainable protection and management of forest resources as well as improve the livelihood of local people. It is also important to have short-term livelihood improvement as well as long-term training to improve the capability of local people.

Early mortality syndrome has damaged largely for both output and profits in aquaculture. According to Lightner (2012) [9], the main cause of early mortality syndrome is caused by genes stick on Vibrio parahaemolyticus which produce toxins maked liver pancreatic atrophy and die. The research team found that EMS was caused by a single strain of a bacterial species common - Vibrio parahaemolyticus. The bacteria are transmitted orally, then it enters the digestive tract of shrimp, creating toxins that destroys tissue, causing dysfunction of liver and pancreatic digestive organs. World scientific community has had to distinguish hundreds of different lines of Vibrio parahaemolyticus, however, only a minority of virulent strains which caused disease EMS on shrimp (Loc Tran et al., 2013) [7], but if the presence of more bacteria and high density will surely cause disease and even lethal to aquatic animals. Therefore, finding the causes as well as measuring to limit the Vibrio parahaemolyticus bacteria that caused disease in the pond is essential.

THE ENVIRONMENTAL IMPACTS OF INTENSIVE SHRIMP FARMING IN TAM GIANG LAGOON: IMPORTANCE WASTEWATER TREATMENT SYSTEM
Lịch, Nguyễn Quang
Tuấn, Lê Công
Linh, Vệ Quốc
This paper investigated the effects of intensive shrimp farming on environment in Tam Giang lagoon and the potential strategies for sustainable management of water pollutant discharged into the lagoon. Shrimp farming has developed rapidly in recent years in the Tam Giang lagoon area in Thua Thien Hue province, Vietnam. Shrimp is the main species farmed, contributing to 65% of all aquaculture products and has brought significant economic benefits to the local community. Although shrimp farming generated quick initial income to the fishing community in the lagoon, the lack of proper planning and poor water management resulted in the discharge of large volumes of effluent into the lagoon system. Besides, farmers using nutrient rich commercial feed and keeping high stocking densities lead to eutrophication, caused mainly by uneaten feed and fish excretion. The increase of commercial feed, chemicals and medicines including advertised substances was used in shrimp farming systems with a aim to gain more income. There are additional impacts on the natural ecological system, such as species diversity, reduction in dissolved oxygen levels as well as an increase in toxic gases (NH3 and H2S) and carbon pollution in the lagoon areas. The integrated wastewater treatment has also been suggested in this study. The system includes three stages (i) toxic gas removal and oxygen level enhancement by mechanical treatment; (ii) biodegradation of organic matter use local fish; and (iii) reuse nutrients to produce aquatic biomass using locally available molluscs and seaweed.

Ngọc, Nguyen Bich
Urbanization is one of the main factors that strongly impact the lives of households whose have agricultural land in the suburbs. Lien Chieu, a district belonging to Da Nang city, is going on its development and has been affected by urbanization as well. The main objective of this study is to analyze the impact of urbanization to income of households whose were revoked agricultural areas by the method of descriptive statistics, regression analysis binary logistic. Research shows that there are six factors that affect the income of the household including education level of the householder, age of householder, number of household workers, dependent rate of people in household, amount of land withdrawn, the use of compensation, which is considered as variable X1, X2, X3, X4, X6, X7, respectively. Each variable affects the income of the household in a different level; in which variables X1, X2, X4, X7 impact positively correlated, whereas X3, X6 impact negatively correlated and reduce the income households after withdrawing agricultural land. Research is also conducted to estimate the probability assuming increasing household income levels at 5%, 10% and 15%, respectively. Based on analytical result, the study proposes a number of recommendations to stabilize household’s income and improve their living standards.

Rumen fluid collected from three fistulated dry cows as inoculum. In vitro fermented attributes were measured after 4, 24, and 48 h of incubation respectively. Results showed that, gas production have been ranked in order rate cassava powder>maize>rice bran. Digestibility of DM and OM, and concentration of ammonia nitrogen (NH3-N), microbial crude protein (CP) and total volatile fatty acid (VFA) had no significantly differed between rice bran and maize. However, these attributes were higher in cassava powder compared to rice bran or maize (P<0.05). In conclusion, rice bran, maize and cassava powder may be recommended for improving fermentation characteristic without any negative impact on rumen environment, however, if using only these feeds as the sole feed for cattle may be inadequate NH3-N for optimal nutrients digestibility and feed intake.

Data for the study was collected from various sources including both primary and secondary sources. The main research approach was to combine scientific and local indigenous knowledge, integrate GIS and participatory mapping. Results showed that the hazards which often occur in Quan Ba district include drought, cold spells and hoarfrost, heavy rain and whirlwinds. Drought usually occurs in Quan Ba district between October and April. The cold spells and hoarfrost usually occur from October to February which is also the time of drought occurring and that dual impact on crops productivity. Heavy rain causing landslides usually occurs between May and July. Whirlwinds occur throughout the year but are predominantly in April to June with increasing intensity. Application PGIS for mapping people’s historical knowledge of the location, frequency, spatial extent, intensity of frequent hazards in Quan Ba district showed not only the specific location of villages and communes affected, but also calculate the affected area at different impact levels by each hazard type in the district. SWOT analysis for exiting natural hazards warning system showed that the climate disaster warning system is limited and the ability to quickly supply hazard related information is limited. Based on that, this study proposed solutions to reduce hazard impacts with multiple hazard approach.

Datum were collected on 216 samples, with 4 repetitions each 54 which collected in different shrimp culture ponds in Quang Dien and Phu Vang, Thua Thien Hue province and isolated of Bacillus strains: B. subtilis A , B and B. subtilis B. Bsubtilis BS. Under culture conditions for microbial strains Bacillus (370C incubation, pH 5-8, concentration of NaCl 1-4 %), different strains of Bacillus has tested with Vibrio. The experiments were tested with 20 strains of Vibrio, which were isolated from the EMS on shrimp. There are 4 strains of Vibrio (cholera, VK1; alginolitycus,VD2; mimicus, X1; parahaemolyticus, X2), which were selected for pairs for inhibition of Bacillus. First results conducted the ability of Bacillus resistance to pathogenic Vibrio as (1) best concentration of Bacillus for inhibition of 107 CFU/ml with Vibrio is 105 CFU/ml and obtained 24.77 ± 0.71 mm of anti-dimension; (2) the optimal time and a highest inhibition after 20 h mixture of Bacillus and Vibrio. Simultaneously, with 12 pairs tested in 3 treatments according to Latin square design and the results were showed two pairs (A - X2) and (A - X1) with maximum anti-dimension of the inhibition to Vibrio, as 35.77 ± 0.83 and 29.83 ± 0.45 mm, respectively. The results and innovation can be announced to farmers and shrimp culture ponds to apply for the prevention of EMS in the region and country.
