AGRICULTURAL FARMING SYSTEMS OF XO DANG ETHNIC MINORITY TO ADAPT CLIMATE CHANGE IN QUANG NAM PROVINCE, VIETNAM

2020-10-14T03:58:24+07:00

This study was performed in Bac Tra My district, Quang Nam province to understand the agricultural farming systems to adapt climate change with 90 households of the Xo Dang ethnic minority. Three principal results are as follows: first, Xo Dang people are aware of the climate change that has a strong impact on their livelihood; most households agree that the droughts become longer; floods and storms become less frequent but with stronger intensity. Second, four adaptation measures were suggested, including (1) adjusting planting calendars, (2) adjusting farming techniques, (3) using native varieties, and (4) intercropping. Finally, among the five principal farming systems, only the intercropping of acacia and local rice (Pế-tru) is the most economically effective with IRR = 10.23%, NPV = 2.6 million, and the payback period of 3.5 years. Two factors significantly affecting the economic effectiveness of this system statistically (p < 0.05) are the acacia variety and the distance from the acacia field to the main road.

STATUS OF COOPERATION AND LINKAGES IN PRODUCTION AND CONSUMPTION OF ORGANIC RICE IN THUY PHU, HUONG THUY, THUA THIEN HUE

2020-10-14T03:58:35+07:00

The authors of this paper use semi-structured questionnaires to survey 60 households producing organic rice to collect the data. The results show that about 80% of the productivity of organic rice is consumed under the contract scheme, and 98% of households follow this scheme. The horizontal linkage among the households is loose, mainly through the oral exchange of information regarding the cultivation techniques with less care concerning the inputs and outputs. The vertical linkage between the households and the enterprises is tight with a contract. The input and output service and the product price are better with the organic-rice production than those with regular-rice production.

Condition and role of agricultural cooperative groups in new rural development in Thua Thien Hue Province

2020-10-14T03:58:40+07:00

Cooperative groups – organizations belonging to a type of collective economics – have been encouraged to develop in developing countries. In Vietnam, cooperative groups were established in the 1960s and played certain roles in agricultural production. Moreover, effective cooperative groups are considered as one of the new rural development criteria. However, few empirical studies have assessed the role of agricultural cooperative groups in Vietnam. This research investigates the situation and role of agricultural cooperative groups in the context of new rural development in Thua Thien Hue province of Vietnam. Data were collected by using a structured questionnaire, supplemented with semi-structured interviews, and relevant documents. Descriptive analysis and qualitative data analysis techniques were used to analyse the data. The results reveal that five main types of agricultural cooperative groups are operating in the study region, namely (1) crop cooperative groups, (2) livestock cooperative groups, (3) food processing/service cooperative groups, (4) fishing/aquaculture cooperative groups, and (5) forestry cooperative groups. The key roles of the agricultural cooperative groups are (1) input provision services, (2) production organisation and linkage, and (3) output provision services. These roles are important for agricultural development, especially in the context of new rural development.

CURRENT SITUATION OF SURFACE WATER MANAGEMENT AND USE FOR PADDY RICE AREA IRRIGATION UNDER DROUGHT CONTEXT IN HOA VANG DISTRICT, DANANG CITY

2020-10-14T03:58:48+07:00

This study was conducted to propose solutions for improving the efficiency of the surface water system for paddy rice areas in the studied locality. The data collection, focus group discussion with the participation of related stakeholders, and field survey procedures were used in the study. The results show that most of the lakes and dams in the study area are of small and medium scale; therefore, the irrigation capacity has not covered the rice cultivation area, especially in the Summer–Autumn season. The use of mobile pumping stations to irrigate drought-prone rice areas is ineffective in high terrain areas. The surface water system has not met the irrigation demand in the district. Under these circumstances, the research has proposed solutions for paddy land use planning, irrigation system development, and local people awareness raising to improve the efficiency of the surface water system for paddy rice cultivation areas under local reality.

ASSESSMENT OF LAND SUITABILITY OF AGRICULTURAL LAND USE IN DA LAT CITY, LAM DONG PROVINCE

2020-10-14T03:58:52+07:00

The aim of this study is the assessment of the land suitability of agricultural land uses in Da Lat City to achieve sustainable agricultural development. Overlapping five physical maps (soil type, soil texture, slope, soil depth, and irrigation), we identified 48 land map units in the entire city, of which 36 land map units (13,412.79 ha) are used for land evaluation. The findings show that agricultural land use types are suitable for the natural and climatic conditions in Da Lat City. In particular, most of the land area is appropriately assessed as levels of S2 and S3 for land uses such as flowers, vegetables, tea, coffee, fruit trees, and food crops. In the future, flowers and vegetables can be upgraded the level of suitability from S3 to S2 with an area of 1,690.29 and 1,062.20 ha, respectively. The trend of land use by 2030 is to increase the area for growing vegetables and flowers and to maintain the area of tea and coffee. Agricultural development in Da Lat City plays an important role in contributing to the economic and social structure, in particular, the land type for flowers and vegetables.

APPLICATION OF KRIGING REGRESSION TO SOIL ORGANIC CARBON MAPPING: A CASE IN HUONG LAM COMMUNE, A LUOI DISTRICT, THUA THIEN HUE PROVINCE

2020-10-14T03:58:56+07:00

Soil organic carbon plays an essential role in the assessment of soil quality, especially for agricultural purposes. This research was conducted in Huong Lam commune, A Luoi district, to understand the influence of slope, elevation, and normalized difference vegetation index (NDVI) on soil organic carbon mapping using the kriging regression model. Soil organic carbon data were obtained from 48 randomly chosen locations at a depth from 0 to 30 cm. Three independent variables consisting of the slope, elevation, and NDVI were extracted from remote sensing data. The results show that the slope is the most influential on the soil organic carbon content with a correlation of 43% compared with 7% and 1% for NDVI and elevation, respectively. The slope could be used for soil organic carbon mapping using kriging regression. More independent variables should be considered to establish the best model for kriging regression

ASSESSMENT OF MANAGEMENT AND USAGE OF FORESTRY LAND IN QUY NHON CITY, BINH DINH PROVINCE

2020-10-14T03:58:59+07:00

The paper assesses the current situation of management and usage of forest land as a basis for proposing solutions to improve the efficiency and management of forestry land in Quy Nhon city, Binh Dinh province. The paper uses 4 methods, namely Data collection, Comparison, Evaluation of the effectiveness of state management and forestry land use, and Data analysis and processing. With the land area for forestry, accounting for 41,5% of the total natural area, the management of forestry land in Quy Nhon city is currently facing numerous difficulties because of the complex level of present fluctuations. The analysis of documents collected from localities and surveys of people and officials in the city reveals that the quality of work performance of cadastral officials in communes and wards is effective and positive. In addition, the summary of each criterion of the state management of forestry land shows that the criteria have a fairly good general score, in which the establishment of working maps and cadastral records management, land evaluation, and land pricing scores the highest rating with 3,39 points. From the average annual benefit-cost ratio (BCR), it can be seen that the economic efficiency of forestry land usage in Quy Nhon has a high level with an average BCR ranging from 1,58 to 1,74. The research shows that the effectiveness of forestry usage in Quy Nhon is relatively high.
