This study critically appraises the Japanese government’s high-level radioactive disposal policy by drawing on three sociological perspectives: risk society, sociology of scientific knowledge, and social acceptance. The risk society theory emphasizes that the Government of Japan and scientists under its control are pursuing nuclear power policy and repository siting within the conventional paradigm of the first modernity, which no longer aligns with the current reality of nuclear power utilization and its public awareness in Japan. Thus, a reflexive response from the policy side is essential to address the demands of a risk society. The sociology of scientific knowledge supports this view by demonstrating that, while scientists under governmental control attempt to convince the public of the safety of their geological disposal methods and the scientific validity of their siting procedures, these claims are largely a social construction of knowledge riddled with uncertainty and ambiguity about inherent environmental risks. The social acceptance standpoint also reveals a substantial bias in government measures toward ensuring distributive, procedural, and interpersonal fairness. Specifically, it critiques the heavy official reliance on monetary compensation to the host community, limited consideration of the allocation of intergenerational decision-making rights based on the reversibility principle, and the implementing agency’s one-way asymmetrical risk communication for public deliberation.

This study examines the impact of gender differences on maize productivity in Dawuro Zone, southern Ethiopia. Our study addressed the limitations of the previous studies in two ways. First, the study separately assessed gender differences in productivity between de facto female-headed households and de jure female-headed households and revealed that female-headed households are not homogenous. Second, the study separately examined the impacts of the covariates on male-headed households and female-headed households using an exogenous switching treatment effect model. We find the existence of gender differences in maize productivity between male-headed households and female-headed households. The maize productivity of male-headed households was overall 44.3% higher than that of female-headed households. However, if female-headed households received the same return on their resources as male-headed households, their productivity would increase by 42.3%. This suggests agricultural policy should target female-headed households to help reduce the productivity gap between male-headed households and female-headed households. Finally, the distributions of the gender differentials between male-headed households and female-headed households are more pronounced at mid-levels of productivity.

Using primary data collected from 560 farm households in Dawuro zone, southern Ethiopia, this study analyzes the gender gaps in food security among male, female, and joint decision-making farm households. It examines the factors inducing gender gaps among the households of those three categories. The results show that female decision-making households have a lower probability of ensuring food-security and a higher probability of being transitionally and chronically food-insecure. Joint decision-making households showed a higher probability of falling into the chronically food-insecure category. The decomposition results show significant gender gaps between male and female decision-making households in terms of food-secure, transitory food-insecure, and chronically food-insecure categories. Overall, both the endowment and return effects account for the gaps; however, the magnitude of the effect from the return is higher than from the endowment on significant gaps in the food-secure, transitory, and chronically food-insecure categories. Hence, there is a need for policies that not only ensure equal levels of productive resources but also help households build their capacity in order to improve both transitory and chronically food insecure situations.

The damaging effects of changing climate on farm-household food security are steadily increasing in sub-Saharan Africa. Adaptation strategies are important for agrarian households to reduce the adverse effects on their food security. This study employed multivariate probit and endogenous switching regression models to analyze the determinants of farm households’ choice of climate-change adaptation strategies, such as the cultivation of early maturing crops, early planting, growing drought-tolerant maize varieties, using precautionary savings, practicing income diversification, and sale of assets, and their effects on household food security in Tanzania. Information on expected rainfall and temperatures, early warning systems, previous droughts, delays in the onset of the rainy season, sex and age of the farmer, educational level, farming experience, family size, total farmland holding, number of livestock owned, contact with extension agents, and access to credit services were all found to influence decisions by farm households to use strategies of adaptation to climate change. Overall, the adaptation of farm households to climate change increased their food security status. An analysis of “adapter” and “non-adapter” farm households showed that the effect of adaptation on food security was smaller for households that adapted than for households that did not. Thus, we recommend that further effective adaptation strategies such as planting drought-resistant crops, changing planting dates, planting early maturing crops, and practicing income diversification be developed and used, particularly for the most vulnerable farm households, to mitigate the adverse impacts of climate change on their food security.

This paper analyzes market participation gaps among male, female, and joint decision-making households, and the factors influencing that gap, using data collected from 560 maize farm households in the Dawuro zone, southern Ethiopia. The results from the ordered probit analysis reveal that female and joint decision-making households were negatively associated with the probability of being a net seller, while being positively associated with being autarchic and net buyers. The decomposition results indicate clear market participation gaps in the net seller and net buyer positions between male and female decision-makers. The mean quantity gaps between males and females are more apparent in the net seller and net buyer positions. Between male and joint decision-makers, the mean quantity gaps are significant in the net seller and autarchic positions, while between female and joint decision-makers, it is significant in the net seller positions. In each market position, the quantity of gaps is unevenly distributed across the quantities of distribution, but the values increase as we approach higher levels of distribution. The gaps in the net seller and autarchic positions indicate that males are better positioned than females and that females are better positioned than joint decision-makers. Both endowment and return effects account for the quantity gaps. Thus, there is a need for policies to secure more equal access to productive resources for female and joint decision-making households and build their capacity to increase their resource returns.

This paper critically examines the consequences of land grabs for livelihoods and agrarian change, based on a case study of rubber plantations in ethnic minorities in the uplands in Northwest Vietnam. Building upon Scoones’ agrarian political economy of livelihood framework, an integrated conceptual framework of a ‘livelihood pathway’ is developed to analyze the impact of rubber plantation land grabs on livelihoods and the agrarian political economy. Drawing on qualitative analysis and survey data from 205 households across six villages inhabited by Thai, Hmong, and Kho Mu communities, this study finds that rubber plantation land grabs have led to differentiated livelihood strategies—ranging from subsistence farming and wage labor to commercial agriculture—shaped by each group’s socioeconomic status, political connections, and access to resources. Consequently, the land grabbing undertaken by a domestic state-owned enterprise has caused the emergence of a set of distinctive livelihood pathways within a complex web of intersections across class and ethnicity in the upland area. This study concludes by arguing that an integrated conceptual framework of a ‘livelihood pathway’ offers a useful tool for analyzing the long-term socio-political consequences of land grabbing in similar contexts across developing countries and beyond.

We examine factors affecting the choice of marketing channels for maize among male, female, and joint decision-making farm households using data from households in Dawuro zone, southern Ethiopia. Econometric results suggest that female and joint decision-makers are more likely to sell maize to consumers or retailers in the main local market where the maize price is higher than to wholesale merchants directly from the farm. Individual decision-makers (male or female) who grow improved maize varieties are more likely to sell to wholesalers directly from the farm. This may be an indication of the effectiveness of joint decisions over individual decisions related to the market price. We also found that improved maize varieties distributed to farmers in the study area are of poor quality and that there is a lack of modern storage facilities so that farmers have to sell immediately after harvest during the lower price season. Thus, there is a need for policies promoting the distribution of high-quality maize seeds and encouraging investments in the establishment of modern maize storage facilities in the study area.

This multi-level study focuses on Thailand’s public good agricultural practices certification standard (Q-GAP) and compares the performance of 100 certified and 229 uncertified growers regarding their pesticide use practices and the levels of pesticide residues detected in on-farm samples. Chili pepper, a crop primarily marketed domestically, was the focal point of this study conducted in the production context of Chiang Mai province. The data for the study were collected through field interview surveys and chili pepper sample collections. The collected crop samples underwent organophosphate pesticide and synthetic pyrethroid analyses using gas chromatography. Statistical analysis techniques, including one-way ANOVA, chi-square tests, probit regression, and multiple linear regression, were employed to analyze the numerical data using the Stata software. The study’s findings revealed several key points. The certified farmers’ main motivation for adopting Q-GAP was to meet market requirements, rather than ensuring safety assurance. They exhibited a significantly lower adoption of insecticides compared to the uncertified farmers, but no significant differences were observed for fungicide or herbicide adoption. The analysis of the pesticide residue results yielded mixed findings, making it challenging to conclude whether certified farmers have better control over pesticide residues compared to uncertified farmers. A probit regression analysis highlighted the critical importance of training for growers’ adoption of the standard.

The local implementation of Thailand’s public good agricultural practices (GAP) certification standard was investigated by examining its effectiveness in raising farmers’ awareness, lowering pesticide use, and thus improving food safety and quality assurance. A total of 98 certified and 100 uncertified farms were surveyed in two Thai provinces, Chanthaburi and Nakhon Si Thammarat, respectively. Considering durian (Durio zibethinus Murr.) cultivation, the economic size of farming in the former region is relatively larger and production more market-oriented, while in the latter region, the farming scale is smaller. It was observed that knowledge and understanding of GAP is much higher among the certified as compared to the uncertified farmers, although the effectiveness of GAP in lowering pesticide use remains unconfirmed. The comparison between the two regions also suggests that farmers’ pesticide use could be affected by other contextual factors to a greater extent than the GAP. Results from a multivariate linear regression analysis highlighted the critical importance of training on Q-GAP and pesticide use in reducing pesticide use among certified farmers. This suggests that GAP applicant farmers should be encouraged to participate in training on those subjects as an integral part of their Q-GAP application or renewal procedure.

EurepGAP is a pioneering field level food safety protocol called ‘good agricultural practices' currently exercising influence over the global food quality assurance system. Developed by a consortium of major European retailers, this private standard enforces codes of conduct that address issues of health and safety for producers and consumers, as well as working conditions and environmental management on the farmland. Despite various merits and benefits that the standard is premised to offer, the institutional design gives a financial edge to powerful large farms and exporters while diminishing opportunities for smaller growers and exporters to remain in the profitable agricultural export sector of the Global South. This paper explores the institutional origin and evolution of EurepGAP, discusses entry barriers and risks that EurepGAP imposes on the global value chain stakeholders, as well as the ethical implications from broader theoretical perspectives. Subsequently, it examines the evolving nature of a new trend in the fresh fruit and vegetable sector, i.e., the rise of public GAP standards. Promoted by some governments in the Global South, these GAP standards emphasize support for horizontal partnerships among value chain stakeholders, farmer participation, and less capital-intensive agricultural innovations. The paper argues that, within certain limitations, these GAP standards have the potential to be the major alternative GAP approach by encouraging a much broader inclusion of small-scale producers towards the attainment of various social, economic, and environmental benefits.
