Efforts to address climate stress recognise climate-smart agriculture (CSA) as a promising approach to minimising the damage caused by increasing weather variability. However, the effect of CSA practices on the resilience of maize farmers in the face of climate variability is not well understood. This study assesses the effects of CSA practices on the resilience of maize farmers. Using primary data from 250 randomly sampled maize farmers in Kenya, a resilience index was generated and then analysed using a structural equation model. The results show that CSA practices increase the resilience of farmers, suggesting enhanced resilience to climate variability. CSA practices improve farmers’ food security and welfare, and their adoption should be promoted.","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":"46707852","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}

Furthermore, to make the food choice decisions even more complex, genetically modified (GM) foods have been introduced in an attempt to meet global food demand. Consumers therefore must make decisions regarding organic and GM foods. This paper investigates consumer heterogeneity for organic and GM tomatoes in Ghana using advanced discrete choice modelling techniques. The data for empirical application come from a choice experimental study conducted among 200 consumers in Ghana. Our econometric modelling revealed that the sampled consumers preferred organic tomatoes that are produced locally and certified by the Food and Drugs Authority. However, we find a likelihood that women and older consumers may have preferences for GM tomatoes with environmental and health benefits. Policy implications are drawn from the findings of the study.","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":"46909743","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}

Domestic wheat markets in Kenya were found to be strongly integrated while, international wheat markets were cointegrated with domestic prices at the port of Mombasa. The long-run elasticity of price transmission was estimated at 0.91, which implies that 91% of the changes in international wheat prices are transmitted to domestic markets in Kenya. The speed of adjustment was estimated at -0.069, which implies that it takes about 14 months for the changes in the international wheat price to be fully transmitted to the Kenyan domestic market. Wheat farmers in Kenya seem to be insulated from international price shocks given the long period of time it takes for domestic markets to adjust to international price changes. Even though not explicitly analysed, government border policies, market and infrastructure impediments seem to be underlying causes of the incomplete price pass-through, along with the low speeds of adjustments. Our analysis suggests that the main constraint to a complete pass-through is the existence of price-setting power at the producer level of the wheat market in Kenya. Investments in infrastructure development and the promotion of liberal trade policies can improve the transmission of international wheat price signals to domestic markets in Kenya.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43754150","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 sample of 401 irrigators in South Africa was analysed using propensity score matching. The study found that group membership had a positive effect on all four outcomes. Group members had an extra four days of access to water in a month, and applied at least 130 kg/ha more inorganic fertiliser, than non-group members. Group members had a higher household income per capita and more assets than nongroup members. However, the result revealed a heterogeneous effect among group members, with the benefits varying according to members’ socio-economic characteristics as well as internal group dynamics. The government and private donors should continue to promote the formation and organisation of farmers into groups. The role of group membership in farming outcomes can be enhanced if smaller groups are promoted.

A multivariate probit (MVP) analytical technique was used to model interrelationships in the control methods from 308 randomly selected livestock keepers. The results show that the current AAT control methods are complementary and not substitutes. Furthermore, the number of years of formal education, household size, household income and land size had mixed effects on the households’ decisions to adopt multiple AAT control methods. The key institutional factors that influenced the adoption behaviour were access to credit, group membership, access to veterinary services and drugs, and agricultural training.

Using experimental data from Nigeria, we examined the source of heterogeneities in preference and WTP for organically produced food. The subjective valuation by consumers of certification in relation to third-party certification and the participatory guarantee system (PGS) was also investigated. A sample of 196 households subjected to a discrete choice experiment yielded 1 764 observations that were analysed using the generalised multinomial logit and mixed logit models. The results reveal a strong preference for food safety in terms of reducing chemical residue, which dominated the respondents’ preference and WTP patterns. Concerning certification attributes, consumers were positively disposed to third-party certification, but showed no significant preference for the PGS form of certification. Significant heterogeneities in preference were due mainly to age and awareness of organic products.

We employed the augmented Dickey-Fuller unit root test, the Johansen co-integration test, the Granger causality test, the vector error-correction model (VECM) and variance decomposition analysis. The Johansen co-integration test confirmed the presence of a long-run relationship across the markets, while the VECM revealed that the speed of adjustment to equilibrium after price shocks in the yam and cowpea markets varied across space (market) and period (time), with the food crisis in the period pre-2007 to 2011 fastest and the food crisis in the period 2007 to 2011 slowest.

The pandemic could profoundly affect the African continent and wipe out hard-won development gains, as sub-Saharan Africa heads into its first recession in 25 years. Beyond the multispatial impact of the coronavirus in Africa, its effects on the agriculture and food system is of particular interest, as food security could be the most affected area and, at the same time, agriculture could be the sector that could help African economies recover quicker from the impact of COVID19. This paper supports the view that COVID-19, as devilish as it may be, offers an opportunity to revive interest in the agricultural sector. The COVID-19 pandemic has placed immense pressures on African countries to raise additional resources, and consequently Africa’s growing public debt is again coming back to the centre stage of the global debate. The conversation on African debt sustainability has begun to dominate the scene and will flood the debate in the near term. While the observed, growing calls for debt relief for African countries are legitimate, we support in this paper that one should not divert attention from the long-term solutions needed to strengthen Africa’s resilience. These long-term solutions lie where they always have: in agriculture. With COVID-19, shipping agricultural inputs and food products from other continents to Africa has become disrupted and is accelerating the trend towards shortening supply chains. This will leave a potential market for inputs and food produced on the continent. COVID-19, together with the launching of the African Continental Free Trade Area (AfCFTA), have aligned the stars in favour of a decisive transformation of the agriculture sector on the continent. Agriculturalists and development experts need to be aware of their responsibility at this time, as they need to advocate for the topic of agricultural development to return to the centre and the heart of the agenda of discussions on how to respond to the consequences of Covid-19 in Africa. In this sense, and unexpectedly, COVID-19 is an opportunity for the agricultural sector.","PeriodicalId":45228,"journal":{"name":"African Journal of Agricultural and Resource Economics-AFJARE","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47304310","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}
