This led to continuous reinvention, development and stretching of the discipline's boundaries. We have seen the same critique by scholars in other disciplines; many of these evolved to thrive or regressed to die. This begs the question, is the agricultural economics discipline evolving and adapting to change or regressing and facing extinction? To answer this evolutionary question, I use the three key pillars that make up the hereditary material of a discipline as a conceptual framework: research, teaching and association. I use several data sets to diagnose the health of each of these pillars to ultimately comment on the health of the discipline. Our findings indicate the weakest pillar as the association. Although our research and teaching pillars are not as strong as we want them to be, we are in the process of reinforcement. In conclusion, the agricultural economics discipline is not in crisis, at least not yet. I also acknowledge that the emergence of crisis does not always lead to the end of a discipline, but it promotes educational reflection and reform to lead to disciplinary evolution.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"62 1","pages":"117 - 132"},"PeriodicalIF":1.3,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48160390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using cross-sectional data collected from 408 households in three districts of East Hararghe Zone, Ethiopia, this study combined two food security indicators namely calorie intake and Food Consumption Score (FCS) so as to gain more insights on the multidimensional nature of food security and to categorise households into different food insecurity groups. The study further sought to identify factors influencing the households’ food insecurity status. The research findings based respectively on the per capita calorie intake and the FCS indicate that 36.03 and 49.02 percent of the sampled households were food insecure. However, the findings reveal that when the two indicators were combined, 22.06 and 40.93 percent of the households were completely food insecure and transitory food insecure respectively. These findings also suggest that the 40.93 percent (26.96 and 13.97 percent) of households categorised as food secure based on single indicators (i.e., per capita calorie intake and FCS respectively) was unrealistic. Furthermore, findings from the bivariate probit model indicate that food insecurity incidences decreased with the adoption of soil and water conservation, access to irrigation, livestock, access to fertilisers, and household income. It increased with the age of the household head, the household size, and the coping strategy index. Therefore, policies and strategies combating food insecurity should consider a combination of food security indicators.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"62 1","pages":"152 - 163"},"PeriodicalIF":1.3,"publicationDate":"2023-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43586155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One climate change adaptation strategy in wheat production in the Western Cape of South Africa is conservation agriculture (CA). Using a data set of 1,043 plot-level wheat observations collected at Langgewens and Tygerhoek research farms from 2002 to 2020, this study conducts a stepwise Life Cycle Assessment (LCA) to estimate the environmental and economic impacts of switching from conventional wheat production to CA’s zero tillage (zero-till) and no-tillage (no-till) systems. The results indicate that CA is more profitable and has a higher environmental efficiency, than conventional tillage wheat production. In Langgewens, zero-till and no-till are respectively 113% and 55% more efficient than conventional tillage when comparing the environmental impact of producing one kg of wheat. Findings also suggest that, compared to 100% conventional tillage wheat production, the adoption of CA systems has led to reductions in environmental damage valued between R269.2 and R402.5 million in the Western Cape.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"62 1","pages":"133 - 151"},"PeriodicalIF":1.3,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49575750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such access can be enhanced through mutual labour support. However, it has become necessary to explore how this form of collective action affects farmers’ productivity and efficiency. In this study, the impact of access to mutual labour support on productivity and technical efficiency was estimated using data collected from 592 smallholder maize farmers in Northern Ghana. The study uses a translog stochastic production frontier model, while accounting for sample selection bias that may emanate from both observable and unobservable household characteristics. Farmers with access to mutual labour support are significantly more productive and technically efficient than those without, with mean technical efficiency in the range of 0.62–0.71 for farmers with access to mutual labour support and 0.55–0.60 for those without access. Sex, education, spraying machine ownership, farm size, extension visits, access to credit, and membership of farmer-based organisation are significant determinants of access to mutual labour support. Policies to help farmer groups and extension agents promote mutual labour support accessibility among farmers are recommended.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"62 1","pages":"61 - 79"},"PeriodicalIF":1.3,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48144773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the gain from agriculture disproportionately trickles down to the poor which can be partly reduced by addressing gender differences in production. Historically, the validity of gender statistics has been questioned as the way researchers and policymakers describe gender differences also affects how they perceive and address them. Amid these antecedents, we apply a meta-stochastic frontier to pooled cross-sectional population-based surveys that represent three decades (1987–2017) of the production history for twelve crops in Ghana to assess the dynamics of gender gaps in technology gaps and technical efficiency (TE). Results indicate that female farmers exhibit technology gap and TE scores of 25 and 76% while their male counterparts exhibit scores of 20 and 73%. The TE gap of 4% against male farmers has remained relatively steady over the three decades while the technology adoption gap against females has reduced from 18% in 1997/98 to 3% in 2016/17. All farmers operate at 60% of the potential possible given the overall crop production technology in Ghana. Over the three decades, the estimated crop production gap of 5.94% against females shifted to a gap estimated at 9.24% against males.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"62 1","pages":"31 - 48"},"PeriodicalIF":1.3,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44568217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
