Past studies have focused on the impact of ISPs on crop production, food security and poverty. Little attention has been devoted to assessing their impact on crop diversification, which is a strategy for managing production risk and improving soil fertility under cereal-based smallholder production environments in SSA. Meanwhile, there is growing debate on whether ISPs may conflict with the crop diversification strategy by promoting crop concentration. We estimate cropland allocation and diversification models to test this hypothesis for two ISPs in Botswana, Accelerated Rainfed Arable Programme (ARAP) and Integrated Support Programme for Arable Agriculture Development (ISPAAD), using panel data of agricultural regions and the cropping seasons of 1978/79 to 2013/14. Results reveal that ISPs have induced increased concentration on cereals, away from beans/pulses and oil crops, leading to reduced cropland diversification. ARAP induced a 6.7 percentage point rise in cereal area share and a 5.2 (1.4) percentage point fall in beans/pulses (oil crops) area share. Similarly, ISPAAD induced a 4.4 percentage point rise in cereal area share and a 4.1 percentage point fall in beans/pulses area share. By discouraging legume production, ISPs may lead to soil fertility loss, as legumes may help rebuild nitrogen stocks in soils.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"59 1","pages":"337 - 353"},"PeriodicalIF":1.3,"publicationDate":"2020-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03031853.2020.1758175","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47392533","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}

Empirical analyses are constructed based on monthly realised frequency data from 2006M1 to 2016M7. The empirical analysis from the full sample size shows that rice, sorghum, price inflation, a nominal effective exchange rate and oil price display weak pass-through among the investigated variables while banana, cocoa, groundnut, maize, soybean and wheat are net transmitters of spillover. Based on these revelations, several policy prescriptions for the agricultural commodity markets and their diverse responses to either exchange rate fluctuations or a dwindling oil price are suggested for Nigeria.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"59 1","pages":"366 - 385"},"PeriodicalIF":1.3,"publicationDate":"2020-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03031853.2019.1694046","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45704617","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}

This paper investigates the determinants of social capital using data from farmers in dairy cooperatives in Ethiopia. First, principal component analyses (PCAs) are performed on the data set of dimensions of social capital: structural, relational and cognitive. After applying PCA, composite indicators are developed as measures of farmers’ dimensions of social capital. Second, seemingly unrelated regression is employed to identify the determinants of the dimensions of social capital. The results suggest that marital status, education level and length of membership have a positive effect on the structural dimension. The relational dimension has a positive relationship with the ownership of a radio, the number of close friends, and membership in associations, while training access and number of close friends positively influence the cognitive dimension. The study concludes that improving farmers’ social capital in dairy cooperatives requires investment in the educational system, creating and developing local associations, promoting cooperatives through mass media, and strengthening the existing training programmes.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"59 1","pages":"303 - 320"},"PeriodicalIF":1.3,"publicationDate":"2020-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03031853.2020.1743728","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43451650","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}

The study estimates the demand elasticities of the three common types of poultry feed; mixed feed, grain, and leafy vegetables. The estimated model was used to obtain estimates of Marshallian demand elasticities for poultry feed in Kenya for male-headed and female-headed households. The elasticities reported can be used by researchers and policy analysts to evaluate policy effects of changes in feed demand quantities within the livestock economy in Kenya. Moreover, these parameters can provide more reliable estimates of the total change in feed demand than relying on subjective measures of elasticities. Furthermore, the results of this study are essential in enhancing gender equitable policy formulation. Our findings show that own price elasticities of demand for all the feed types are negative and less than unit in absolute value for the sample of farmers surveyed, indicating that the feed types are relatively inelastic. The cross-price elasticities indicate that vegetables and grain are compliments while the rest of the poultry feed types are substitutes. The results also show that there are substantial gender differences in feed demand and elasticities of feed demand with respect to feed prices.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"59 1","pages":"426 - 439"},"PeriodicalIF":1.3,"publicationDate":"2020-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03031853.2020.1742747","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41918115","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}

A cross-sectional research design using a stratiﬁed random sample of 279 households was sampled along the urban-rural continuum in Morogoro and Iringa, Tanzania. The results show that household assets ownership varies signiﬁcantly in areas regarded as urban, peri-urban and rural. Using binary logistic regression, household food accessibility improves as household head's education and the number of household members earning income increase. Conversely, food accessibility worsens as household size, the proportion of consumption expenditure on food, and reliance on aid increase. It is concluded that although household assets ownership varies greatly along the urban-rural continuum, its food accessibility status is influenced by factors such as household head's education level, number of members earning an income, household size, the proportion of consumption expenditure on food and reliance on aid. Household's location does not aﬀect its food accessibility. Therefore, household's heads should be given appropriate technical skills to enable them to improve their household food accessibility. More job opportunities should be created mostly in rural areas and people should be sensitised to practice family planning.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"59 1","pages":"354 - 365"},"PeriodicalIF":1.3,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03031853.2020.1743729","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44513921","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}

Improved sorghum varieties are widely regarded as a panacea to extreme poverty. The paper uses endogenous switching regression to determine impacts of improved sorghum varieties intensification on household welfare. Household dietary diversity score and household food insecurity access score were used as outcome variables and proxies for food security. Cross-sectional data were generated in the Mid Zambezi Valley of Zimbabwe in 2016 from 380 households in a survey conducted with five purposively selected wards. Social association groups, average weighted market prices, household income, age of principal decision maker, dependency ratio, ownership of draught power and storage facilities have significant (p < 0.01) implications on the adoption decision. Counterfactual analyses shows that farmers who allocate more land towards improved sorghum varieties are relatively better off in food diversity and food access. Intensifying improved sorghum varieties can increase dietary diversity by 35% while reducing food insecurity by 29–34%. Social networking can be strengthened through local, government and private partnerships to facilitate generation and efficient dissemination of sorghum production and marketing information. Improving the market prices can increase market size and enhance efficiency along strategic value chain nodes.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"59 1","pages":"254 - 267"},"PeriodicalIF":1.3,"publicationDate":"2020-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03031853.2020.1721306","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59306007","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}

Current estimates point to over 1 billion tons of food lost and wasted worldwide, though nearly 10 percent of the global population is suffering from undernourishment and food insecurity. In Mozambique, about one-quarter of the population suffers from undernourishment and food insecurity. Estimates from FAO point to postharvest losses of maize in Mozambique at about 3.69 to 7.92 percent; this is less than one-fifth of the on-farm losses reported by other authors. In this study, an Equilibrium Displacement model is used to assess the economy-wide impact of postharvest losses of maize at the farm level. The impact of a 3 percent postharvest loss is tested. Results suggest that even this very conservative percentage of postharvest losses has a direct annual net cost of around $USD 28 million for both farmers and consumers domestically. This is equivalent to over 1 percent of the national budget. It is also higher than the average cost of food aid programs received over the last three years. Therefore, reducing postharvest losses of maize along with other interventions is crucial to achieve sustainable development and economic growth.","PeriodicalId":55541,"journal":{"name":"Agrekon","volume":"59 1","pages":"235 - 253"},"PeriodicalIF":1.3,"publicationDate":"2020-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03031853.2020.1721305","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42410186","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}
