The data were obtained from General Household Survey fielded by the National Bureau of Statistics in 2010/2011 and 2015/2016. However, only 1,619 matched observations were used for analyses, using Propensity Score Matching, Double Difference, Foster-Greer-Thorbecke poverty measures and Poverty Equivalent Growth Rates (PEGRs). The results show that 53.3% of participants lived below the poverty line (poor) in 2011, while in 2016, this proportion declined to 31.94%. The poverty incidence of female participants (0.5504) decreased by 53.68% while that of male participants (0.4112) decreased by 4.81%. If female participants had not participated in non-farm enterprises, their poverty would have been reduced by only 9.7% but due to participation, it was reduced by 53.68%. The Poverty Equivalent Growth Rates are higher for all the three FGT measures than the actual growth rates for all participants, males and females with females showing higher poverty reduction; which means that growth was propoor, although the poverty of the poor decreased more than that of the core poor. Also, after five years there is a decline in poverty incidences of participants across the six geopolitical zones and the decline was mostly felt in the North East (NE) followed by North Central (NC) while the least percentage decline was seen in North West (NW). Since participation in non-farm activities had a significant impact on the poverty of participants, the promotion of non-farm enterprises among poor farmers should be encouraged.","PeriodicalId":30385,"journal":{"name":"Journal of Agribusiness and Rural Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49640162","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, there is a need to identify priority areas to unlock industry potential. The study sought to highlight particular areas within the  Zimbabwean pork industry where value creation could offer the industry advantage. A survey of 24 pork butchers, 6 pork processors and 166 pig farmers from Mashonaland Central Province was utilised in the study. Descriptive statistics, correlation, ANOVA and multiple regression were used to analyse the data. The results highlighted that the industry regarded value creation through advantage in the acquisition of inputs, goods and services, production/processing, and logistics, which consequently makes those key target areas. Furthermore, the created value (profit/cost ratio) was influenced by the category of agribusiness, distance to markets, business practice and socio-economic dynamics of the business decision-makers. In conclusion, production and processing, as well as inbound logistics, were identified to be less effective in value creation. However, increasing transportation advantage will likely improve value. The study recommends that the pork industry leverage on production/processing, inbound logistics and transportation. Policy implications relate to the creation of a conducive environment in input procurement and transportation. The study adds insights for business strategy and policy formulation, aiding in enhancing turnover and strategic positioning","PeriodicalId":30385,"journal":{"name":"Journal of Agribusiness and Rural Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47106389","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}

Similarly, just under half had farming experience of more than 21 years and consisted of 6-10 household members. Although, most agricultural households in the study area were food secure, however food insecurity was very high. The marital status, education level of respondents and annual farm income were positively and significantly associated with food security. The majority of the farmers were old, had low levels of both education and farm income. Findings of this study highlight the level of food security in the study area and show that food insecurity levels amongst agricultural households was approximately twice the South African national household food insecurity.

Literature suggests that IC production plays a vital role in rural communities of South Africa as an important source of animal protein and income. Despite these claimed benefits, production of indigenous chickens in Alice and other parts of South Africa’s rural areas is very low. This study used a cross-sectional survey of 120 households who keep IC in Alice communal area. The multivariate probit model was employed to investigate the factors that determine the choice of indigenous chicken owned by rural households. Results reveal that, gender, age, household size, association membership, access to formal markets, access to veterinary services, access to informal credit, access to formal credit and diversity score drive ownership of different indigenous chickens at household level. Thus far, the paper argues that, promotion of ownership of indigenous chicken at household level calls for strategic institutional alignment and a clear understanding of social demographic characteristics of the targeted community, which should be supported by several awareness campaigns and client based selection of indigenous chicken breeds of socio-economic importance to the household.","PeriodicalId":30385,"journal":{"name":"Journal of Agribusiness and Rural Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46836850","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}

Limited input availability and precarious environmental conditions determine smallholders’ decisions on their production and the production efficiencies vary from farmer to farmer. This study was carried out with the aim of analyzing the technical, allocative and economic efficiencies of smallholder farmers in the production of major crops and their determinants in central Ethiopia, Oromia special zone surrounding Addis Ababa. Multistage sampling technique was employed to randomly and proportionally select 386 smallholders from ten PAs. Primary data were collected from smallholders through a semi structured questionnaire using face to face interview. Cross sectional data collected from sampled households in the study area were analyzed using mathematical and econometric methods. Mathematical programming technique selected for this study was Data Envelopment Analysis (DEA) using linear programming technique assuming multi-input and multi-outputs were handled. Tobit regression model was regressed against the socioeconomic, demographic, and institutional variables that are expected to affect the technical, allocative and economic efficiencies of sampled households. The results of estimated efficiency scores show the mean technical, allocative and economic efficiencies were 0.75, 0.60 and 0.45 respectively. The mean scores of efficiencies show underutilization of resources and the possibilities of smallholders to increase their agricultural production by 25%, and reduce cost of production by 40% and total cost by 55%. Marital status, level of education, farming experience, access to credit, cooperative membership, access to farming information, and off/non-farm income has positive influence on the technical, allocative and economic efficiencies. While age of the household head, access to training and livestock size has negative relations to efficiencies. Delivery of agricultural inputs and trainings on time by the government is the key policy implication to improve the efficiencies of smallholders. \u0000 ","PeriodicalId":30385,"journal":{"name":"Journal of Agribusiness and Rural Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44894507","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}

Secondary data were obtained from Food and Agricultural Organization and the World Bank. Descriptive statistics, trend equation and correlation analyses were used. Findings revealed that agricultural and arable land utilization grew at the rate of 0.62% and 0.72%, respectively per annum; while the total population growth rate stood at 2.57%. Also, urban and rural population grew at a rate of 4.75% and 1.67% respectively. In addition, the agricultural and arable land utilization rates had significant positive correlations with the total population, urban and rural population. Besides, the findings revealed that, agricultural land (to total land ratio) has continued to increase and currently averaged at 68.78% indicating massive land expansion put under agricultural used. Findings revealed that, most arable crop outputs increase majorly from land expansion rather than land productivity, a situation that cannot assure sustainable agricultural land use food security in a near future. Hence, the country needs agricultural land sparing policies and technologies to slow the current agricultural land expansion drive. Besides, the country’s agricultural land policies should focus on achieving land productivity and sustainable land-sharing strategies among major land users in the country. Again, the rural population growth rate is lower than the urban growth rate, implying that, the rural population is deteriorating with its probable negative effect on farm labour. This needs to be addressed urgently if the sustainable agricultural system is to be achieved in the near future in Nigeria.","PeriodicalId":30385,"journal":{"name":"Journal of Agribusiness and Rural Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42517323","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 study used an adapted, fit-for-purpose market systems development framework to review available research in extension and advisory services in selected sub-Sahara Africa countries. Using a literature survey methodology, we report evidence of multiple actors in extension delivery, findings that point towards evolution towards mixed delivery as well as objectives. While there are significant uptake of cost-recovery approaches among commercially-oriented farmers, many smallholder farmers still depended on donor-funded services. Our review adds to existing knowledge through incorporating a market systems development framework, which extends the often-used willingness to pay approach, and highlights the need for merger of both public and private-sector objectives to achieve developmental outcomes.","PeriodicalId":30385,"journal":{"name":"Journal of Agribusiness and Rural Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43412834","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}

Therefore, the study examined the impact of information communication technologies on the technical efficiency of fish farming in Ogun State, Nigeria using a stochastic production frontier approach. In a cross-sectional survey, a multi-stage sampling technique was employed to elicit primary information from 120 fish farmers. Major ICT sources used by the fish farmers include television (81.7%), radio (79.2%) and the Internet (68.3%). The average output of catfish has positive and significant elasticity with regards to each input variable except family labour. The inefficiency model revealed that the age of farmers, farming experience, television and radio usage were significant but negatively related. That means that any increase in any of these factors will reduce the inefficiency of fish farmers and bring about an increase in technical efficiency. This implies that it is possible to increase technical efficiency in fish farming in the study area provided that the media channel (radio and television) predominantly used is improved. This study recommends a reduction in family labour usage while at the same time encouraging young people to venture into fish farming.","PeriodicalId":30385,"journal":{"name":"Journal of Agribusiness and Rural Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44180849","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}
