Cognitive social capital, which is based on commonly shared norms among subjects, leads to honest and cooperative behaviour. It is necessary for ease of information flow, a reduction in transaction costs, and allowing communities to deal with social dilemmas like common-pool resource management. The study used incentivised economic experiments on randomly selected subjects drawn from a control group (non-MCF students) and a treated group (MCF students). The experimental results from the two groups were compared to check the differences in terms of levels of trust, reciprocity, altruism, cooperation, in-group favouritism and out-group discrimination. Our results show that the scholarship programme has a significant impact only on levels of in-group favouritism and out-group discrimination. The post-experimental survey showed that MCF and non-MCF subjects were similar in terms of stated pro-social behaviour perceptions and in-group social capital creation.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42760805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The survey relied mainly on institutional and primary data for its analysis. Primary data was obtained from arable crop farmers using a set of structured questionnaires administered in a multi-stage, stratified random sampling manner. Sixty (60) farmers were selected from randomly selected states for the five agroclimatic zones in Nigeria, giving a total sample size of 300 farmers. The collected data was analysed using Heckman’s probit selectivity model. It was found that extension contact, gender of the head of household, temperature and rainfall levels determined the decision to adapt to climate change. The respective Z estimates of these aspects were 5.75 (p < 0.01), 5.30 (p < 0.01), 2.32 (p < 0.01) and -9.50 (p < 0.01). However, the farmers’ perceptions of climate change effects were determined by education and agricultural extension access. The Z values for these were 5.42 (p < 0.01) and 2.86 (p < 0.01) respectively. The researcher recommends urgent measures to help farmers adapt to climate change, such as the establishment of weather stations and building the capacities of farmers, especially women.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43280434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet the majority (68%) of Ugandans rely largely on rain-fed agriculture, which is affected by climate variability. This study therefore investigates the effect of climate variability on agricultural productivity in Uganda by combining long-term climate data, sourced from the United States National Oceanic and Atmospheric Administration (NOAA), and six waves of the Uganda National Panel Survey (UNPS) spanning the period 2009 to 2019. Trends and the regression analysis estimated with panel data confirm the existence of climate variability, as well as the vulnerability of farming households across Uganda. The empirical results indicate a significant U-shaped impact of precipitation variability on agricultural productivity. This tends to suggest that, as variability in precipitation intensifies, farming households will adapt to the changing precipitation and thereby improve their productivity. The regional and crop-specific analysis show that, relative to other regions of the country, Eastern Uganda is likely to be the region affected the most, while beans and banana are likely to be affected more by climate variability compared to other crops such as maize and cassava. The study thus recommends measures aimed at encouraging farmers to adapt and increase agricultural productivity. There is a need to strengthen the provision of extension services and inform farmers about climate variability","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135922450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies remain inconclusive about whether the adoption of SAPs has any bearing on the efficiency of maize farmers. The current study introduced the concept of sustained adoption and compared levels of efficiency between one-time SAP adopters and sustained adopters. Using a sample of 2 100 households, the study employed the Cobb-Douglas stochastic frontier model to analyse both the technical and profit efficiency of maize farmers, and a two-stage tobit model was used to control for endogeneity. The study found that the one-time adoption of SAPs has no effect on the technical efficiency of maize farmers, whilst sustained adoption significantly improves the technical and profit efficiency of maize farmers. The study recommends a shift towards promoting the sustained adoption of SAPs for sustainable benefits for farmers.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42658776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vector error-correction model framework was used to estimate the causal relationships between the short- and long-run market price. The results indicate that a higher proportion of price variation in larger markets in the region was due to market price shocks, while variation in the smaller markets originated from the larger markets. Weekly adjustments and the convergence of prices on a long-run equilibrium after experiencing shocks were also observed. Price transmission was also evident between markets operating along different trading routes. However, markets located close to production catchments exhibited lower price trends, despite being connected. These results suggest a strong influence of the recent infrastructural investments on price transmission between markets in the region. The findings imply that more investments would enhance the competitive trading environment and reduce unidirectional price transmission.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41569640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
