Perceptions and practices of pesticides safety measures of rice farmers in the central region of Vietnam
The use of pesticides is increasing rapidly and the pesticide use crisis is badly damaging the environment, the economy, and public health in Vietnam. However, the country is yet to become successful in reducing pesticide use mostly because of policy implementation and inadequate understanding of farmers. This study examined and discussed the perceptions and safety level of using pesticides by applying a widely used index of 39 indicators equivalent to 39 safety measures grouped into four categories to assess the safety behaviour of rice farmers in the central region of Vietnam. A field survey of 320 rice farmers and 12 local leaders was conducted in Quang Tri and Thua Thien Hue provinces. The result revealed that there exists a significant difference (p0.001) between the perception and practices of pesticide safety measures of rice farmers in the study area. The overall score appears relatively high (4.09 and 3.89 out of 5.0 for perception and practices, respectively), indicating that farmers believe what they are doing is safe, though there are significant variations among the categories and among farmers in practicing pesticide safety measures. Regarding the farmers’ safety level, it was observed that there are still 18.1% and 34.4% of rice farmers are under unsafe and potentially unsafe conditions, respectively. Hence, an effective extension and communication program regarding the management and safety use of pesticides is the most vital policy solution to protect the rice farmers from potential health risks and ensure the sustainability of agriculture
CSA: Thực hành nông nghiệp thông minh với khí hậu ở Việt Nam
During the last five years, Vietnam has been one of the countries most affected by climate change. Severe typhoons, flooding, cold spells, salinity intrusion, and drought have affected agriculture production across the country, from upland to lowland regions. Fortunately for Vietnam, continuous work in developing climate-smart agriculture has been occurring in research organizations and among innovative farmers and entrepreneurs. Application of various CSA practices and technologies to adapt to the impact of climate change in agriculture production have been expanding. However, there is a need to accelerate the scaling process of these practices and technologies in order to ensure growth of agriculture production and food security, increase income of farmers, make farming climate resilient, and contribute to global climate change mitigation. This book aims to provide basic information to researchers, managers, and technicians and extentionists at different levels on what CSA practices and technologies can be up scaled in different locations in Vietnam
Estimation of methane emissions from local and crossbreed beef cattle in Daklak province of Vietnam
Objective: This study was aimed at evaluating effects of cattle breed resources and alternative mixed-feeding practices on meat productivity and emission intensities from household farming systems (HFS) in Daklak Province, Vietnam.
Methods: Records from Local Yellow×Red Sindhi (Bos indicus; Lai Sind) and 1/2 Limousin, 1/2 Drought Master, and 1/2 Red Angus cattle during the growth (0 to 21 months) and fattening (22 to 25 months) periods were used to better understand variations on meat productivity and enteric methane emissions. Parameters were determined by the ruminant model. Four scenarios were developed: (HFS1) grazing from birth to slaughter on native grasses for approximately 10 h plus 1.5 kg dry matter/d (0.8% live weight [LW]) of a mixture of Guinea grass (19%), cassava (43%) powder, cotton (23%) seed, and rice (15%) straw; (HFS2) growth period fed with elephant grass (1% of LW) plus supplementation (1.5% of LW) of rice bran (36%), maize (33%), and cassava (31%) meals; and HFS3 and HFS4 computed elephant grass, but concentrate supplementation reaching 2% and 1% of LW, respectively.
Results: Results show that compared to HFS1, emissions (72.3±0.96 kg CH 4 /animal/life; least squares means± standard error of the mean) were 15%, 6%, and 23% lower (p < 0.01) for the HFS2, HFS3, and HFS4, respectively. The predicted methane efficiencies (CO 2 eq) per kg of LW at slaughter (4.3±0.15), carcass weight (8.8±0.25 kg) and kg of edible protein (44.1±1.29) were also lower (p < 0.05) in the HFS4. In particular, irrespective of the HSF, feed supply and ratio changes had a more positive impact on emission intensities when crossbred 1/2 Red Angus cattle were fed than in their crossbred counterparts.
Conclusion: Modest improvements on feeding practices and integrated modelling frameworks may offer potential trade-offs to respond to climate change in Vietnam
Environmental entitlements: institutional influence on mangrove social-ecological systems in Northern Vietnam
Environment and development issues are complex and interdependent. Institutions underpinning state, private sector and civil society actions at various levels must address complexity to ensure social-ecological system integrity. However, responses often operate at only one governance level, with limited interactions with other levels, restricting their ability to support communities who depend on natural resources for their livelihoods. This paper explores institutional factors influencing household entitlements to mangrove system provisioning goods on Vietnam’s northern coast. The environmental entitlements framework is used to identify: (1) current formal and informal institutional structures relating to mangrove systems; (2) the influence of state, private sector and non-governmental organisation actors at various levels; and (3) how actions occurring at and among various levels of governance shape mangrove system entitlements at the local level. Employing a case study approach, this research utilises qualitative methods and a multi-level governance approach to understand prevailing institutional contexts. Results indicate that reforms occurring within weak regulatory frameworks led to the concentration of power at the meso level, reducing the endowments of marginalized households. Market forces facilitated inequality and environmental degradation, negatively impacting household entitlements. Finally, a lack of formally recognised civil society constrained household capabilities to participate in mangrove planning. Mangrove dependent households must be integrated into mangrove planning at the local level, as processes at higher institutional levels affect household environmental entitlements and threaten sustainable outcomes. Ensuring views from the local level feed into the multi-level governance process is vita
Socializing One Health: an innovative strategy to investigate social and behavioral risks of emerging viral threats
In an effort to strengthen global capacity to prevent, detect, and control infectious diseases in animals and people, the United States Agency for International Development’s (USAID) Emerging Pandemic Threats (EPT) PREDICT project funded development of regional, national, and local One Health capacities for early disease detection, rapid response, disease control, and risk reduction. From the outset, the EPT approach was inclusive of social science research methods designed to understand the contexts and behaviors of communities living and working at human-animal-environment interfaces considered high-risk for virus emergence. Using qualitative and quantitative approaches, PREDICT behavioral research aimed to identify and assess a range of socio-cultural behaviors that could be influential in zoonotic disease emergence, amplification, and transmission. This broad approach to behavioral risk characterization enabled us to identify and characterize human activities that could be linked to the transmission dynamics of new and emerging viruses. This paper provides a discussion of implementation of a social science approach within a zoonotic surveillance framework. We conducted in-depth ethnographic interviews and focus groups to better understand the individual- and community-level knowledge, attitudes, and practices that potentially put participants at risk for zoonotic disease transmission from the animals they live and work with, across 6 interface domains. When we asked highly-exposed individuals (ie. bushmeat hunters, wildlife or guano farmers) about the risk they perceived in their occupational activities, most did not perceive it to be risky, whether because it was normalized by years (or generations) of doing such an activity, or due to lack of information about potential risks. Integrating the social sciences allows investigations of the specific human activities that are hypothesized to drive disease emergence, amplification, and transmission, in order to better substantiate behavioral disease drivers, along with the social dimensions of infection and transmission dynamics. Understanding these dynamics is critical to achieving health security--the protection from threats to health-- which requires investments in both collective and individual health security. Involving behavioral sciences into zoonotic disease surveillance allowed us to push toward fuller community integration and engagement and toward dialogue and implementation of recommendations for disease prevention and improved health security
HIỆU QUẢ SẢN XUẤT LÚA JO2 TẠI XÃ PHÚ HỒ, HUYỆN PHÚ VANG, TỈNH THỪA THIÊN HUẾ
The data were collected from interviews with 60 households participating in JO2 rice conversion, focus group discussions, and in-depth interviews with knowledgeable people. Descriptive statistical analysis and the Likert scale were used to evaluate the factors affecting the efficiency of the production. The results show that although the Khang Dan rice variety still gives a high yield, it is no longer resistant to wind and rain, falls more easily and is more susceptible to pests and diseases. JO2 rice has high production costs but thanks to its high quality and selling price, bringing economic and social benefits to farmers. We identified nine factors affecting JO2 rice production; among them, experience is the essential factor in helping farmers facilitate production, but the market factor hinders access to information. Other drawbacks were also addressed, and measures to improve production efficiency were suggested to apply the model in the future.Dữ liệu được thu thập từ phỏng vấn 60 hộ tham gia chuyển đổi trồng lúa JO2, thảo luận nhóm và phỏng vấn sâu người am hiểu. Phương pháp phân tích thống kê mô tả và thang đo Likert được sử dụng để đánh giá các yếu tố ảnh hưởng đến hiệu quả sản xuất lúa JO2. Kết quả cho thấy giống lúa Khang dân tuy vẫn cho năng suất cao nhưng không có khả năng chống chịu mưa gió, dễ đổ ngã và sâu bệnh nhiều. Lúa JO2 có chi phí sản xuất cao nhưng cho gạo ngon và giá bán cao nên mang lại hiệu quả kinh tế và xã hội cho nông hộ. Chín yếu tố ảnh hưởng đến sản xuất lúa JO2, trong đó, kinh nghiệm là yếu tố quan trọng nhất, nhưng thị trường vẫn là yếu tố cản trở việc tiếp cận thông tin. Các yếu tố còn hạn chế cũng được đánh giá và các giải pháp để nâng cao hiệu quả sản xuất lúa JO2 được đề xuất, góp phần tiến đến nhân rộng mô hình trong tương lai
The Impacts of COVID-19 on Returned Migrants’ Livelihood Vulnerability in the Central Coastal Region of Vietnam
This study investigated the impacts of the COVID-19 pandemic on livelihoods of households with migration workers, who returned home to the central coastal region during the peak disease outbreak in Vietnam. Five hundred and twenty-nine households with returned migration workers aged eighteen and above in the coastal areas of Quảng Bình, Quảng Trị, and Thừa Thiên Huế provinces participated in this study. Results showed that the livelihoods of all studied households were highly vulnerable due to impacts of the COVID-19 pandemic, with almost 90% at moderate or high risk according to the vulnerability index. All livelihood assets were negatively affected, and financial, psychological, and social assets were the most affected, with Common Vulnerability Score System scores of 3.65, 3.39, and 3.17, respectively. Male, younger workers, or those with a lower education level and fewer social networks were found to be more vulnerable than others. This study suggests that young laborers could aim to attain a higher level of education and/or practical skills to be able to obtain stable employment with benefits such as social insurance if they desire to out-migrate. Further, social programs which allow for migration workers at the destination to meet each other may have positive impacts on their vulnerability
Using a social learning configuration to increase Vietnamese smallholder farmers’ adaptive capacity to respond to climate change
Social learning is crucial for local smallholder farmers in developing countries to improve their adaptive capacity and to adapt to the current and projected impacts of climate change. While it is widely acknowledged that social learning is a necessary condition for adaptation, few studies have systematically investigated under which conditions particular forms of social learning are most successful in improving adaptive capacity of the most vulnerable groups. This study aims to design, implement and evaluate a social learning configuration in a coastal community in Vietnam. We make use of various methods during four workshop-based interventions with local smallholder farmers: interviews with key farmers and commune leaders, farmer-to-farmer learning, participatory observations and focus group discussions. The methods for evaluation of social learning configuration include in-depth interviews, focus group discussions and structured survey interviews. Our findings show that the social learning configuration used in this study leads to an increased problem ownership, an enhanced knowledge-base with regard to climate change impacts and production adaptation options, improved ability to see connections and interdependencies and finally, strengthened relationships and social cohesion. The results suggest that increased social learning in the community leads to increase in adaptive capacity of smallholder farmers and improves both their economic and environmental sustainability. We discuss the key lessons for designing learning configurations that can successfully enhance adaptive capacity and smallholder farmers’ agency and responsiveness to the challenges posed by climate change impacts.</p
