To account for heterogeneity in the MAI adoption decision and unobservable farm and household attributes, we estimate an endogenous switching regression (ESR) model. The findings reveal that size of land endowment, access to farm credit and awareness of farm advisory services are the main driving forces behind MAI adoption. The analysis further shows that MAI adoption increases household farm income, farm yield and equivalised consumption per capita. This implies that adopting MAI is the most consistent and potentially best pathway to reduce poverty among rural farmers. The study hence suggests that policymakers should align the effective dissemination of MAI information and farm advisory services, strengthen farm credit systems and improve market access – most crucially at affordable prices – among small-farmers throughout Rwanda.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70629856","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}

However, most previous studies were undertaken within a setting of mixed cropping systems. In this article, we investigate the effect of farm size on productivity within the context of a perennial monocropping system, acute competition for farmland, frequent subdivision of farms and declining yields. We apply household survey data of smallholder tea farms in western Kenya and consider both technical efficiency (TE) and the yield per hectare as indicators of productivity. The findings show that the effect of farm size on productivity is nonlinear, with TE initially declining and then rising with farm size. The findings also demonstrate that the farm size and productivity relationship is important for perennial monocrops and that the use of robust measures of productivity is important for the IR. The findings have important implications for agricultural policy in developing countries.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45241834","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}

However, diseases such as African animal trypanosomosis (AAT) have limited the potential of this important sector in the rural household economy. Using a representative sample of small-scale cattle farmers, this study investigates the adoption of modern AAT-management technologies in rural Ethiopia. Specifically, this study investigatesthe adoption of so-called ‘best-bet technologies’ (BBTs), recommended by veterinary experts as complementary measures to manage AAT. The results show that the multiple adoption of BBTs was low. In addition, BBTs were adopted as substitutes, and not as complements as suggested by veterinary experts. The results suggest budgetary constraints are proxied by wealth, and information asymmetry explains the substitution effects. The training and reeducation of veterinary personnel, as well as programmes and interventions that would improve access to livestock-management inputs, should be pursued vigorously by policy makers to increase the adoption of modern AAT-management technologies to improve cattle productivity.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48854823","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}

Also, the study found that public expenditure (proxied by government expenditure on the agricultural sector) and private investment (proxied by commercial bank credit for the agricultural sector) are complementary investments in promoting agricultural productivity, while public expenditure on the agricultural sector and foreign direct investment are substitute investments. The study recommends that budgetary allocation to the agricultural sector should be increased, and that commercial banks should be strengthened through the monetary authority by advancing more loans to agricultural businessmen and businesswomen at a reduced lending rate.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46692180","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}

This paper explores the relationship between novel measures of cropping-season weather conditions and household food consumption in rural Niger, and how household coping mechanisms mediate that relationship. We employ a panel logit model to show that the normalised difference vegetation index (NDVI) and extreme heat degree day (EHDD) measures are associated with subjective self-reporting of drought in a panel dataset of 2 264 households. We then show, with a household fixed-effects panel model, that low NDVI and high EHDD measures are associated with significant decreases in household per capita food consumption. Household coping strategies, such as the disbursement of savings, temporary migration of a family member, and the adoption of heat-resistant agricultural technologies, are found to partially mitigate, but not fully alleviate, the negative effects of weather shocks on consumption. More comprehensive coping mechanisms are needed to improve household resilience to weather shocks.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41353688","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}

A flexible translog profit function that permits the application of the primal approach to the output supply and factor demand analysis was estimated using household-level data. The results indicate that the own-price elasticities of supply for cattle, sheep and goats were all positive. The own-price elasticities for the supply of sheep and goat products were elastic, while the own-price elasticities for the supply of cattle products wasinelastic. Cross-price and scale elasticities were found to be within the inelastic range in all cases, with goat production complementing both cattle and sheep production. All factor input demand elasticities for cattle, sheep and goats had the expected negative sign and were inelastic. These results offer a valuable opportunity for the development of pro-pastoral price policies that reduce factor market imperfections and thus enhance livestock productivity in the rangelands of Kenya.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41595008","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 technology gap ratios (TGR) are 0.25 and 0.04 for the MMF and FMF respectively. The results suggest that both MMFs and FMFs are technically inefficient. However, the production technology operated on MMFs is relatively superior to that operated on FMFs, as shown by the relatively higher TGR for MMFs.

Relying on large household datasets from 2010 and 2013, we explored the resilience of Malawian households to the exogenous shocks of flooding and currency devaluation during this period. We utilised two strategies for understanding resilience. The first, a classification framework pioneered by Briguglio and others, categorises households into resilience and vulnerability spaces. The second approach employs econometric analysis to explore food security resilience. These two complementary analyses reveal that infrastructure, assets, education and non-agricultural employment opportunities contribute most to food security resilience.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46821705","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}

We focus on foodborne diseases associated with the microbial contamination of animal-sourced foods. The results of our analysis indicate that governments in all three countries have official programmes to limit foodborne diseases and mitigate the effects of outbreaks. However, the population in these three countries continues to experience a high burden of foodborne diseases, and knowledge of the specific causes and mitigation of these diseases in SSA is lacking. Furthermore, there is a need for more and better food safety education programming, as we found no study that has collected a representative sample to estimate the level of public awareness of foodborne pathogens in any of the three countries studied. Evidence also suggests that institutional capacity around food safety in both the public and private sectors is insufficient due to limited financial investment and technical capacity.

Using data collected from 113 randomly selected households growing Bambara in the Wenchi and Nkoranza municipalities in southern Ghana, we estimate the factors influencing preference decisions and the intensity of the desired attributes using probit and Poisson regression models respectively. Preference for an improved Bambara variety is influenced by experience in farming, availability of extension services, credit access, membership of farmer-based organisations, plant type, seed colour, household size and yielding capacity. The attributes desired the most by farmers are high yielding capacity, high protein content, branched plant type and seeds that are dark or brown in colour. Furthermore, key factors influencing the number of attributes desired in an improved Bambara variety include the farmer’s sex, education, years of experience in Bambara cultivation, household size, membership of farmer-based organisations and extension services. There is a need to consider these varietal attributes and the factors as integral to research and development efforts, as well as to the policy agenda, to enhance the adoption of improved Bambara varieties for increased productivity and incomes of smallholders in Ghana.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44409018","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}
