Yet no study has systematically analysed this theme in Zimbabwe, an area that we address. Data was collected from 331 randomly selected farm households in four districts of Zimbabwe. Factor analysis was used to compute resilience capacities. Poisson regression was used for model estimations. Assets, market diversity and social capital increased dietary diversity by 7.5%, 3.6% and 2.9% respectively. Interventions that enhance asset accumulation, for example incomegenerating activities, should be promoted. Promoting farmer groups and collective actions are important to strengthen social capital. Adaptive and absorptive capacity increases dietary diversity by 5.9% and 5.4% respectively. Household resilience is positively associated with dietary diversity. The public and private sectors and civil society need to promote interventions that build adaptive, absorptive, and overall resilience capacity of farming households to enhance food security.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41383054","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}

In this paper we estimate the impact of the programme using high-quality household survey data from 2013/2014 and 2016/2017. Using the panel data, the double-difference model shows that households that borrow increase their stock of livestock. This is confirmed by the cross-section inverse probability-weighted regression adjustment models, which also find that VUP borrowing leads to more purchases of farm inputs, greater consumption (especially of home-produced food), lower poverty, and greater secondary school enrolment, but not to more hours worked. While VUP loans account for only 2% of the value of microcredit in Rwanda, they do help fill a need for production credit at a scale large enough to be able to help households appreciably increase their agricultural and other assets, and ultimately their income.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46303667","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}

In this context, this paper examines the effect of the targeted fertiliser subsidy implemented in Togo from 2017 to 2019. For this purpose, the propensity score matching and instrumental variables regression approaches were used to control for potential selection and endogeneity bias. Nationwide crosssectional survey data covering 2 319 smallholder farmers in Togo suggests that participation in the targeted fertiliser subsidy programme significantly improved beneficiaries’ poverty status through increased income, leading to a decline in poverty incidence, gap and severity. However, the magnitude of the effect is very small compared to that in some other West African countries. Therefore, to enhance the effect of targeted subsidy policy on income and poverty status, there is a need to improve the rate and composition of the subsidy.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49246583","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 Government of Togo, through the National Programme for Agricultural Investment and Food Security (PNIASAN) and the Agricultural Sector Support Project (PASA), and with financial support from the World Bank and help from the Food and Agriculture Organization of the United Nations (FAO), provides assistance to smallholder farmers in improved technology adoption in traditional poultry farming (ITTPF) for wealth creation, food security and poverty alleviation. However, for any technology or emerging agricultural practices, awareness and exposure are necessary conditions for their adoption. And because these two factors are not distributed randomly in the population of potential adopters, not taking them into account will lead to estimates of population adoption rates that are not informative of the true demand for the technology, and to inconsistent estimates of the parameters of the adoption model. In this study, we evaluate the adoption rates of ITTPF among farmers in Togo. Data was collected from 400 farmers in 2014, prior to the introduction of ITTPF, and again five years later. This data was then analysed using inverse propensity score weighting and parametric estimation of adoption regression models. The results of the estimates indicate that the average treatment effect (𝐴𝑇𝐸), which represents the mean potential adoption rate of the population, is 57%, the average treatment effect on the treated (𝐴𝑇𝐸𝑇), which represents the mean potential adoption rate in the exposed subpopulation, is 60%, the population mean joint exposure and adoption rate (𝐽𝐸𝐴) is 13%, and the population selection bias (𝑃𝑆𝐵) is 3%. The sample adoption rate (𝐽𝐸𝐴) implies a population adoption gap of -47% due to a lack of exposure and adoption by a sufficient size of the population. The 𝑃𝑆𝐵 is insignificant and indicates that all the sampled farmers had an almost equal opportunity of adopting ITTPF. The study reveals that the sample adoption rate does not consistently estimate the true population adoption rate. Hence, controlling for non-exposure and selection biases is a perquisite to acquiring consistent estimates of ITTPF adoption rates. The findings indicate a relatively high supply-demand gap for ITTPF that justifies investment in its further dissemination and adoption in Togo for optimal positive impact on potential outcomes and the welfare of farmers.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45347308","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}

Instrumental-variable tobit (IV tobit) was used to determine the causality between women’s empowerment and household poverty. The results reveal that poverty levels in households with empowered women are low compared to households without such women. Besides, education level, credit access, market access, land size, and crop and income diversification contributed positively to women’s empowerment and to the reduction in household poverty. The domains that contribute significantly to women’s disempowerment in sugarcane farming are income, work balance and leadership. These results suggest that strengthening women’s control over income and their leadership position in society are vital domains that should be targeted by rural development interventions to improve the livelihoods of smallholder women sugarcane farmers. In addition, there is a need to intensify crop diversification and increase women’s access to markets.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45103605","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 has prompted the seed sector to introduce various varieties of climate-smart maize in Kenya and release them in the market. In contrast, there is little experiential insight into how the adoption of these varieties by small-scale farmers affects their household income. This paper used cross-sectional data to evaluate the implications of climatesmart maize varieties on small-scale farmers’ household income in Embu County in Kenya. The endogenous switching regression model was used to estimate the influence of climate-smart maize adoption on household income. Based on survey data obtained from 550 maize farmers in Embu County, the results show that age, education, land under climate-smart maize varieties, and distance to the market positively influenced the income level of the adopters. The findings further reveal that the decision to adopt the climate-smart maize varieties had a significant positive effect of about 60% on farmers’ household income. It therefore can be concluded from the results that the adopters would gain more from technology adoption. These results recommend policies that stimulate the adoption of current climate-smart varieties, with an emphasis on adoption by youths, to create more jobs and increase household income to reduce poverty among smallholder farmers in Kenya","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43899407","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}

Bashaasha","doi":"10.53936/afjare.2022.17(3).18","DOIUrl":"https://doi.org/10.53936/afjare.2022.17(3).18","url":null,"abstract":"Women’s time allocation is a dimension of women’s empowerment in agriculture, and is recognised as a pathway through which agriculture can affect child nutritional status in developing countries. Longer hours of farm work can potentially increase women’s time constraints, reducing the time allocated to child-caring responsibilities and raising the risk of poor child nutritional status. Using a three-wave household panel dataset from the Feed the Future Innovation Lab on Nutrition surveys in the north and southwest of Uganda, we tested the hypothesis that the negative effect of women’s agriculture time-use constraints on child stunting is mitigated for households that use labour or timesaving agricultural technologies (LSATs). The results show a positive and significant association between the number of hours per day that women spend on agricultural work and the risk of stunting in children aged zero to 23 months who live in households that do not use animal traction for ploughing. However, this association is statistically insignificant, and even turns negative for households that adopted the labour-saving technology. Our findings indicate that LSATs have the potential to lessen a household’s agricultural workload, giving mothers more child-caring time, and hence improving child nutritional status. Therefore, agriculture could have better nutritional outcomes if policies and programmes were designed to have interventions that reduce the workload in farming activities and thus reduce pressure on women’s time.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45167138","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}

Many feel that more investment in cowpea research and development is needed for the crop to achieve its economic potential. Cowpea has long been labelled a ‘women’s crop’. We tested whether this is the case in Mali by exploring five indicators with a combination of primary and secondary databases, and interpreting our results in the context of the regional literature. We conclude that, in Mali, cowpea is better characterised as a ‘women’s enterprise’. Men are more likely than women to plant cowpea as either a primary or secondary crop and tend to plant larger areas, with cowpea intercropped. In drier agro-ecologies, women are more likely to grow cowpea than other crops. Although subsample sizes are very small, women cowpea growers appear to earn more on average from selling the harvest from their individual plots than do men. Women represent 99% of traders of processed cowpea products in the open-air markets we surveyed. In the production segment of the value chain, investments to facilitate women’s access to improved cowpea seed and local markets would support their commercial orientation. Investments in women’s trade in processed cowpea products, including the provision of credit, storage, and training in organisational capacity, would enhance their incomes and their livelihoods.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49327926","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 most effective value chains to be efficiently supported through R&D investments are traditional export crops, groundnuts, rice, poultry, sorghum/millet and cattle. Other promising value chains with potential effects at scale include vegetables, oilseeds and fruits.
