Farmers have a long history of adjusting their production practices in response to changing production conditions. Using a multinomial endogenous treatment effects model that accounts for observable and unobservable heterogeneity, this study investigates the adoption and welfare impacts of climate‐resilient practices on Vietnamese rice‐cultivating households. We found evidence of clear and positive welfare impacts from the adoption of canal irrigation (CI) and the joint adoption of agricultural conservation practices (CP) and CI as the main adaptation strategies to increase water stress. More importantly, although farmers with access to CI systems obtained the highest returns, the joint adoption of multiple practices still had substantially high adoption rates and significantly positive effects on rice yield, rice revenue and household income. Our findings indicate that farms' and farmers' characteristics, market information and climatic conditions are generally the main factors driving rice farmers' decisions to adopt climate‐resilient technologies, both individually and jointly. Follow‐up policy interventions should focus on improving CI systems and promoting the joint adoption of climate‐resilient technologies to improve rice farmers' well‐being and enhance their resilience capacity to cope with incoming climatic uncertainty.
Extending protected areas has enabled global species and habitat protection, especially for endangered species. In addition, understanding social preferences for species protection is essential to contribute to the biodiversity conservation efforts of protected areas. The main purpose of the study was to investigate the preferences of international tourists towards the protection of the northern yellow-cheeked gibbon (Nomascus annamensis) through a proposed wildlife conservation program in Bach Ma National Park, Central Vietnam. Data for the study was collected from a face-to-face survey of 361 randomly selected foreign tourists visiting Bach Ma National Park. By using the dichotomous choice contingent valuation approach, we estimate international tourists' willingness to pay (WTP) for the proposed conservation program of gibbons and identify elements that influence their WTP for the conservation program. We found that international tourists strongly support conserving gibbon populations in the Bach Ma. The findings from the logistic regression model in the study reveal that the respondents' bid level, education, knowledge, biodiversity conservation, climate change, and revisit variables were all significantly predictive of WTP. The estimated mean WTP amount for one-time funding of the species conservation program was US$7.83 per international tourist. The obtained results of this study suggest that policy-makers and managers of national parks should consider the significance of international visitors' support for gibbon conservation efforts when designing and developing their social strategies, programs, and policies for protecting nature and preserving biodiversity, particularly with regard to tourism segmentation in protected areas.
Shrimp farmers in Vietnam respond passively to market risks, such as input and output price shocks. This study provides a better understanding of market risks, risk management strategies adopted by shrimp farmers, the factors driving their choice of strategies, and how such strategies affect farm performance. Random sampling was used to collect information from a sample of 246 shrimp farmers. Several analytical methods were combined, including descriptive analysis, coefficient of variance estimation for market risks, and a logistic regression model to uncover factors behind farmers’ decisions to adopt risk management strategies. To cope with market risks, shrimp farmers frequently adopt two risk management strategies: changes in farming technology and practices, and agricultural input contracts. Overall, 54.9% of shrimp farmers only used a single strategy, whereas the others used combined risk management strategies. Age, farm size, membership in a farmers association, participation in training, gender, price of output, price of seed, price of fertilizer, distance from farm to the market center, and shrimp type were identified as factors driving the probability of using combined risk management strategies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
