Gender preferences for multiple attributes of soil and water conservation in Northern Rwanda

Despite the dominance of female labor in agricultural production, female-controlled farm plots have lower efficiency compared to plot managed by male-headed households, which indicates a huge gender disparity in agricultural productivity. Overlooking gender preferences when designing interventions that promote the conservation of soil and water resources might face challenges in adoption and could result in ineffective policies to close the gender gap. This study seeks to analyze gender-specific preferences regarding attributes of soil and water conservation (SWC) in northern Rwanda. A best-worst survey was conducted among 653 respondents, comprising 253 males and 400 females, representing 422 households surveyed between September and December 2019. The analysis of BWS data involved assessing attribute-level relative importance, Pearson correlation, and maximum difference scaling using multinomial logit (MNL). Findings from attribute-level importance analysis revealed significant gender-based disparities in preferences across three important SWC attribute scenarios: the high scenario (between 65 % and 100 %), the moderate scenario (between 50 % and 65 %), and the basic scenario (with <50 % relative importance). The study identified heterogeneity in preferences regarding the relative importance of SWC attribute levels. Pearson correlation analysis revealed substantial synergies among attribute levels linked to land consolidation, improved land tenure, and joint SWC decision-making between genders. Additionally, the study identified trade-offs among multiple levels of SWC attributes, including households' SWC decision-making and physical and structural measures. The results from MNL regression show that both males and females exhibit positive preferences for multiple levels of SWC attributes, but show negative preferences when it comes to household decisions involving multiple SWC strategies. The study highlights the importance of equal opportunities for males and females’ participation in agricultural transformation through the adoption of SWC technologies as a fundamental step towards sustainable agricultural intensification. It advocates for gender transformational approaches to incentivize the scaling up of SWC practices and promote packages with lower uptake rates. Additionally, the study suggests enhancing knowledge and extension education in SWC to better understand diverse needs and preferences of female farmers.

Consumers' Preferences for Chicken Fed on Different Processed Animal Proteins: A Best-Worst Analysis in Italy.

The increase in meat consumption expected in the next decade will require more and more proteins for animal feeding. The recent amendments to the European "BSE Regulation" allow the use of insects and porcine-based meals in poultry farming, providing novel, sustainable substitutes for vegetable fodder. While the technological and nutritional properties of novel feeds containing processed animal proteins are widely recognized, far less is known about consumers' acceptance of meat produced by animals fed on animal-based meals. In the present research, a best-worst survey was applied to estimate consumers' preferences for chicken fed on plants, insects, or porcine-based meals using a sample of 205 Italian consumers. Furthermore, product price, type of farming, and "Free-from" labeling were considered in the analysis to evaluate the relative importance of feed ingredients compared to other important attributes of meats. The results show that the most relevant attributes are type of farming and "Free-from" claims, while type of feed represents the third attribute in order of importance. Notably, both insect and porcine flour are considered as negative characteristics of the product, suggesting that mandatory labeling signaling the use of these feeds would negatively impact on the value of chicken meat.

Eliciting Preferences for Clinical Follow-Up in Patients with Head and Neck Cancer Using Best-Worst Scaling.

There are no commonly accepted standards for monitoring patients treated for head and neck cancer. The aim of this study was to assess patients' preferences for different aspects of follow-up. A best-worst survey was conducted in a sample of head and neck cancer patients in clinical follow-up at the National Cancer Institute (Milan, Italy). Conditional logit regression with choice as the dependent variable was run to analyse the data. A covariate-adjusted analysis was performed in order to identify socio-demographic and clinical factors related to the selection of best-worst items. The participants were asked to report any difficulties encountered during the survey. A total of 143 patients, predominantly male (74%) and with a mean age of 58 years were enrolled in the survey. The strongest positive preference was expressed for a hospital-based program of physical examinations with frequency decreasing over time. Conversely, the lowest valued item was not performing any positron emission tomography (PET) scan during follow-up. Patients with high educational levels were more likely to value attending a primary care-based program and undergoing intensive radiological investigations. Other patient-specific variables significantly associated with the choice of items were employment and living status, time already spent in follow-up and number of treatments received. Overall, patients were more likely to choose an intensive follow-up scheme broadly consistent with the program currently administered by the hospital. There is little evidence of preference heterogeneity that might justify customized programs based on demographics. The best-worst scaling task appeared feasible for most participants.

Water policy debate in Australia: Understanding the tenets of stakeholders’ social trust

The increasing physical and economic scarcity of water due to increasing societal demands and climate change will require worldwide water policy reform. Water reform is an area of public policy fraught with polarised positions regarding community and environmental welfare. As opposition to water policy reform becomes entrenched, transaction costs increase. Nowhere is this more evident than the controversy surrounding, and irrigators’ opposition to, the Murray-Darling Basin Plan in Australia. This study sought to understand irrigators’ trust issues and why they feel the way they do towards water reform, though a best-worst survey methodology and regression analysis. The results suggest that irrigators believe they are shouldering a fair share of the water reform burden. Lack of trust in the national water agency and the federal government is associated with irrigator location, age and climate change disbelief. Findings support the recent push for more localised water decision-making to promote social trust.

L06 - Analysis of patients' preferences for post-treatment clinical follow-up in head and neck cancers

Objectives: There are no commonly accepted standards for monitoring patients treated with a curative intent for head and neck cancer. The aim of this study was to assess patients' preferences for different aspects of follow-up (FU) programs. Incorporate the perspective of patients in clinical practice could enable the development of customed FU, which may increase acceptability, satisfaction and participation of patient. Moreover, in an era of limited economic resources, more targeted programs to needs of the recipients may prove cost-effective than conventional strategies adopted so far. Methods: A best-worst survey, that suggested 9 different scenarios of hypothetical follow-up programs, obtained from a statistical combination of attributes and levels relating to visits frequency, tumor evaluation frequency, phone contacts to assess the onset of clinical symptoms, was conducted in a sample of head and neck cancer patients in clinical follow-up at the National Cancer Institute (Milan, Italy). Conditional logit regression with choice as the dependent variable was run to analyse the data. A covariate-adjusted analysis was performed in order to identify socio-demographic and clinical factors related to the choice of the items. Results: A total of 143 patients were enrolled in the study; participants were predominantly male (74%) and had a mean age of 57.6 years. The strongest positive preference was expressed for a hospital-based program of physical (and endoscopic) examinations with frequency decreasing over time. Conversely, the lowest valued item was not performing any positron emission tomography (PET) scan during follow-up. Patients with high educational levels were more likely to value attending a primary-care program and undergoing intensive radiological investigations (MRI/CT scans). Other patient-specific variables significantly associated with the choice of items were the time from the end of cancer therapies and the number of treatments received. Conclusions: Overall, patients were more likely to choose an intensive follow-up scheme broadly consistent with the program currently administered by the hospital. There is little evidence of preference heterogeneity that might justify customized programs; however, timing of radiological investigations modulated according to the follow-up stage might be considered in this cancer setting.
