  This study assesses the awareness and adaptive behavior of farm households toward climate change in agricultural production across three representative ecological regions: the Red River Delta (Nam Dinh), the Central Highlands (Dak Lak), and the Mekong River Delta (Soc Trang). Primary data were collected from 764 farm households through structured interviews and analyzed using descriptive and comparative statistics. The results show that most farmers were aware of common climate change signs such as rising temperatures (72.5%) and unseasonal rainfall (53.4%), but their understanding of long-term impacts like declining farmland remains very limited (4.5%). The proportion of households applying adaptive measures such as adjusting cropping seasons or changing crop and livestock varieties was still low (22%). However, more than 86% of those who applied these measures reported moderate to high economic benefits. The main barriers to adaptation included lack of technical knowledge (68.05%), limited investment capital (69.3%), and insufficient access to government support (56.4%). The study suggests enhancing technical training, improving access to climate information and small-scale financial assistance, and integrating climate adaptation criteria into rural development programs to narrow the gap between policy goals and actual practices at the household level

  Since 2009 up to date, over 7,000 specimens of coffee scale insect infected with mycopathogens in three provinces in the Central Highland, i.e. Dak Lak, Dak Nong, and Gia Lai were collected, among these 360 specimens were selected for isolation. 25 strains of insect fungi were identified based on morphological and molecular characteristics and 6 parasitic species were identified including: Beauveria bassiana, Metarhizium anisopliae, Cephalosporium lanoso-niveum, Cordyceps nutans; Toxicocladosporium sp., and Paecilomyces cicadae. Virulence test by in vitro evaluation of  extracellular enzyme activities showed that 8 strains as MR3, MR4, MR8, MR9, BR5, BR11, BR13 and BR16. These strains showed high potential for mass product to control scale insect on coffee. The optimal temperature for growth and development of these strains ranged from 25 to 280C. At 300C fungal strains of BR2, BR4, BR7, BR10, BR11, BR13, and BR16 can grow well. The best substrate for mass product of these strains was rice. Application of bio-products under laboratory condition showed that highest control efficacy was 77.78% with strain BR5, followed by 74.45% with strain MR4.

  This study explores the factors influencing the poverty of indigenous ethnic minority households in Dak Nong province. The study used the Binary Logistic regression model with a sample of 178 indigenous ethnic minority households, including poor households, and non-poor households. The results showed that the poverty rate of indigenous ethnic minority households is still high, accounting for 22.8% compared to the general poverty rate of Dak Nong province of 6.98%. In addition, we found that the factors affecting poverty of indigenous ethnic minority households included family size, education level, total farmland area, access to loans, participation in social organizations, diversification of livelihoods, communication means and natural disaster. Therefore, it is necessary to strengthen the implementation of family planning programs, improve education levels, career transition support policy, build and upgrade information and communication systems, and improve capacity to respond to disaster risks for indigenous ethnic minority households.

  The process of land accumulation and concentration has occurredin Dak Nong province. However, this process still reveals many limitations and has not met the needs of the province's commodity agriculture development.Based onassessing the current situationand analyzing factors affecting the process of land accumulation and concentration over time, thisstudyproposedsolutions to accelerate the process of land accumulation and concentration for commodity-oriented agricultural developmentin Dak Nongprovince. This study appliedthe participatory approachmethodto collect primary data, combinedboth qualitative and quantitative methodsin data analysis. Ourresults showedthat for the farm group, land accumulation took place in the form of buying and renting land from other farmers, while for the cooperatives, land concentration in the form of sharing land rights between farmers and entrepreneurs was dominant. The fluctuation of the land market and the resources of the actors involved in land accumulation and concentration were key factors influencingthe process of land accumulation and concentration.

  This study was to evaluate the efficiency of vocational training for rural labor in Dak Lak province based on different perspectives and participants' views. The respondents involved are 49 Officials of the State Management of Vocational Training, 40 vocational training institutions, 223 teachers, 450 vocational trainees and 15 employers. In gathering the data, a survey with questionnaires and interviews was conducted. In the analysis of the data collected, descriptive, statistical division, and scoring methods were used. Results showed that the vocational training for rural labor in the province of Dak Lak had achieved certain results and this effect is different when viewed in the different respects. However, in order to further improve the efficiency of this activity in the province, it is necessary to focus on implementing key solutions such as: improve the quality of demand forecasting and building training quotas; strengthen the quality of training via building flexible and appropriate training programs and methods, at the same time increasing investment in facilities, training, and remuneration for teachers; Apply new training fields with potentials, advantages of each locality and take them in to local development plans and programs; support post-trained labors in job creation and self-employment.

  Dak Nong Province, a newly established province in the central highland, has on going processes of landuse changes in both agriculture production and forestry land from 2000 to present. The research showed that the total area of ​​forest land lost at this stage is estimated at 131.725 ha (approximately 20% of total natural area of ​​the province). This is an alarming figure due to the specific geographic location and, the deforestation in Dak Nong will affect the ecological environment not only in the province but also the surrounding regions in Central and Southeast provinces. Investigation through household interviews and working with related departments at provincial and district levels as well as consulting the scientists, the research identified the trend of arable and forest land use as well as the main cause of losing forest in the period from 2000 to 2012 . The solutions toof agricultural and forest land use in Dak Nong province were also prposed.
