The objective of this study was to determine the price attributes of Döhne Merino wool in South Africa using a hedonic model and data from 83 registered Döhne Merino farmers in South Africa. The results indicated that the price of Fleece wool was most sensitive to changes in the staple strength, staple length, and fibre diameter, while clean yield had a lower impact. Fibre diameter had the largest effect on the price of Pieces wool, followed by staple strength and staple length. The Bellies wool price was very sensitive to changes in clean yield, followed by staple length. It is recommended that Döhne Merino wool with higher staple strength and longer staple length should be produced due to the price premiums that could be earned. The findings provide evidence of the demand for quality attributes associated with wool and could aid Döhne Merino wool producers in deciding how to maximise their profit. Woolgrowers and other interested stakeholders could use this information to ensure that wool quality meets market demand.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"60 1","pages":"31 - 42"},"PeriodicalIF":1.3,"publicationDate":"2021-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03031853.2021.1879659","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45565187","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, maize yields in Rwanda have remained low due to the limited adoption of fertilisers and improved seed varieties. This study aims to analyse factors that influence the timing of adoption of fertilisers and improved seed varieties (i.e., intensive agricultural practices) in Rwanda. The duration analysis approach is applied, providing a statistical method that permits the timing of the adoption event to be explicitly modelled in a dynamic framework. The results highlight the importance of social learning and information acquisition through extension services, media, and a network of fellow farmers in increasing adoption rates for fertilisers and improved maize varieties. Similarly, membership in farmers' associations, access to credit, and risk-loving behaviour positively affect the speed of adoption. Policy insights from the study suggest that strategies for promoting faster adoption should focus on providing information through agricultural extension services, media, and a network of fellow farmers. Additionally, farmers' cooperatives should be given priority as a dissemination pathway that can increase adoption speed for fertilisers and improved maize varieties.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"60 1","pages":"43 - 56"},"PeriodicalIF":1.3,"publicationDate":"2021-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03031853.2021.1883448","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44820747","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}

To account for potential selection bias, non-Gaussian and missing data problems, a robust two-stage Bayesian instrumental variable approach is used to determine the impact of dairy farmers' participation in ICAs on household income and milk revenue. Data are from smallholder dairy farmers in Zambia. We find that male household heads, wealth, experience selling to milk collection centres (MCCs), livestock holding, milking parlour ownership, landholding, and access to marketing information positively affect farmers' probability to participate in ICAs. However, increased off-farm income and distance to MCCs limit their participation. While some socioeconomic variables have significant positive effects of affecting ICA participation on household welfare, we find no sufficient evidence of causal effects of ICAs on household incomes and milk revenue among dairy farmers. Thus, while ICAs enhance smallholder farmers' access to markets, they may not address high rural poverty rates in developing countries. We provide some insights by which performance of ICAs in the dairy sector may be improved.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"60 1","pages":"10 - 30"},"PeriodicalIF":1.3,"publicationDate":"2021-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03031853.2021.1875854","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44075639","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}

Results indicate that there has been no technical progress in the sector over the past decade and group members are falling further behind their own benchmark as time passes. Relative rankings have remained stable, with most of the group riding the peaks and troughs of good and bad years without breaking rank. There is clearly room for fresh thinking. Drought does not offer a simple explanation for the observed trends. This group’s total factor productivity is inversely correlated with farm size despite evidence that their technology is increasing returns-to-scale. This is difficult to explain. Woolled sheep seems to be the solution to drought, but too much land under planted pastures lowers overall efficiency. There is much more investigation to do, including to cast the net wider so that a more sophisticated efficiency model can be fitted. There was no information on heat stress or rainfall variability, or the date of adoption of conservation agriculture, which is known to be a good strategy against unreliable rainfall. We also could not model the effect of farmers’ skills and ambitions on their performance. The study’s main contribution is to debunk the myths that rainfall places an absolute limit on performance and that a larger scale of operation is always beneficial.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"59 1","pages":"387 - 400"},"PeriodicalIF":1.3,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03031853.2020.1828116","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44722408","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}

Based on a literature review covering a broad range of topics, the article derives four main conclusions. First, more market-oriented agricultural policies and trade liberalization improve horizontal price transmission in global agricultural markets. Second, in the integrated agricultural markets, some regions tend to lead the price discovery process, which is determined mainly by their role in international trade. Third, with the growing integration of agricultural markets, the significance of local factors such as seasonality is diminishing. Fourth, as markets become more integrated, spontaneous public interventions aimed at the stabilisation of domestic prices are less effective. These findings may help market participants at all stages of the food supply chain to better understand how policy deregulation and trade liberalisation affect price setting in agricultural markets and, consequently, enable them to adjust to these changes more effectively. Furthermore, the paper provides policy implications, as it distinguishes the institutional factors determining the degree of price transmission in agricultural markets and emphasises the decreasing effectiveness of domestic agricultural and trade policies as globalisation in agricultural markets continues.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"59 1","pages":"412 - 425"},"PeriodicalIF":1.3,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03031853.2020.1831936","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46859389","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}

Findings show that effective rainfall is the main determinant for livestock farming in the Namibian arid areas, much more than stocking rates or other variables suggested in earlier literature. Advanced analysis shows that the inclusion of known rainfall cycles in production decision making can improve the farm gross margin by 15.9%, which reduces volatility. The findings call for extension services to avail early warning systems that will enable livestock farmers to cushion the impact of gross margin volatility.

The study utilizes a multinomial endogenous switching regression model in the empirical estimations to account for sample selection bias caused by observed and unobserved farmer attributes. In addition, the study employed Mundlak fixed effects criteria to address plot level heterogeneity. The results show that joint adoption of SAPs improves total value of output and reduces hidden hunger, relative to adoption of SAPs in isolation. Specifically, an increase in total value of output is at most USD8,288.66/ha whiles decrease in cereal self-provisioning capacity is at most 647.69 kg per adult equivalent. The results therefore suggest that joint adoption of the SAPs should be promoted over adoption in isolation. The results also indicate that the benefits associated with adoption of SAPs, either in isolation or jointly, vary across Africa. This therefore implies that compatibility and potentials of the SAPs in various locations of Africa should be considered when promoting uptake of SAPs.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"59 1","pages":"440 - 458"},"PeriodicalIF":1.3,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03031853.2020.1855219","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43221604","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}

An improved understanding of the key drivers underpinning the performance of cooperatives is important for informing government programmes and policies that target cooperatives. This study examined the financial efficiency, and its determinants, of 387 agricultural cooperatives in South Africa, using the Simar–Wilson methodology. Bias-corrected Data Envelopment Analysis estimates for financial efficiency were obtained in the first stage. The results indicated that many agricultural cooperatives are relatively inefficient, compared to the three best-performing cooperatives on the efficient boundary. In the second stage, a double bootstrap truncated regression model was used to obtain bias-corrected scores that excluded the best-performing cooperatives. The statistically significant efficiency determinants identified from the analysis were the age and size of the cooperative, the gender of the principal manager of the cooperative, its governance and the training indicators. The observed relationship between governance and efficiency may be attributed to institutions that prioritise non-financial goals by being relatively more willing to compromise on governance quality. Furthermore, deviations from sound institutional control mechanisms are more likely to emerge in cooperatives that have weak institutional and organisational arrangements.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"59 1","pages":"269 - 286"},"PeriodicalIF":1.3,"publicationDate":"2020-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03031853.2020.1761845","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42413965","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}
