However, existing literature often overlooks differences among smallholders. Using surveys, life interviews, and focus groups, this study applies the Household Access Food Insecurity Scale and dietary diversity scores to examine how household heterogeneity among Ghanaian tree-crop farmers affects FNS. Beyond standard FNS dimensions, we incorporate food sovereignty aspects like autonomy, cultural preferences, and sustainability. Only 47% of households were food secure, with significantly higher rates among those growing multiple tree crops (58%) and lower rates among landless farmers (30%). Households dependent on a single tree crop and landless households experience seasonal food insecurity due to low incomes. Interestingly, even the most economically secure multiple tree-crop households do not always achieve better dietary diversity, as spending choices influence nutrient intake. Cultural preferences impact FNS, particularly for older generations, while younger generations exhibit shifting dietary trends, highlighting the importance of cultural and generational factors. Intercropping is key to future FNS, given the widespread conversion of food-crop lands to tree-crop production. However, intercropping becomes difficult as tree crops mature, and excessive agrochemical use threatens sustainability and food safety. These findings underscore the need to explore intercropping in oil palm plantations, promote livelihood diversification, and raise awareness of more inclusive and sustainable farming practices. Future FNS research, policy, and practice must account for household heterogeneity and specific production contexts.","PeriodicalId":520973,"journal":{"name":"NJAS impact in agricultural and life sciences","volume":"97 1","pages":"2508143"},"PeriodicalIF":0.0,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12327230/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144796643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One potential example of circular agriculture is recycling the by-products of insect production (frass) as a crop and soil health promoter. This research investigates the drivers of arable farmers' intentions to trial insect frass as an input on their farms using the Theory of Planned Behaviour and the Innovation Decision Process. In addition, the influence of group discussion participation on the drivers of farmers' intentions is investigated to identify potential opportunities to influence the uptake of frass. Two questionnaires at two time-points (t1 and t2) were distributed to forty-six Dutch arable farmers. Between these time-points, half of the farmers participated in group discussions where their first impressions of frass were shared amongst each other. The results from several regression models suggest that in t1, farmers' attitudes, perceived (descriptive) social norms and perceived behavioural control drive their intentions to trial frass. By t2, for those not in group discussions, attitudes were the only significant predictors of their intentions. For those who participated in the group discussion, the descriptive norm had a larger association with intentions than for those who did not. The results of this research contribute to an informed discussion on how group discussions, alongside policy-driven approaches, can serve as a mechanism for shaping perceptions and beliefs and influence the adoption of agricultural innovations like frass.","PeriodicalId":520973,"journal":{"name":"NJAS impact in agricultural and life sciences","volume":"97 1","pages":"2501385"},"PeriodicalIF":0.0,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12327226/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144796642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
