Bien que l’économie africaine en général et celle de l’Afrique de l’ouest en particulier demeure fortement dépendante du secteur agricole, ce dernier s’avère être le moins productif parmi les trois grands secteurs considérés de l’économie, notamment le secteur agricole, industriel et des services.
This paper analyses the heterogeneous effects of membership of a farmer group on access to water, use of inorganic fertiliser, household incomes, and farm asset holdings. 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.
While irrigation is key to boosting agricultural productivity in Burkina Faso, it may come with hidden health costs. Drawing on data from over 1 000 households in the Sourou Valley and using propensity score matching, this study uncovers the unintended consequences of irrigation for public health.
This paper investigates the extent of price volatility of maize and rice in Ghana following the introduction of public buffer stockholding operations (PBSO) as a policy to stabilise farm output prices in the last decade.
Dans le but d’appréhender l’influence des types de contrat de travail sur les performances des exploitations cacaoyères dans le Mbam et Kim au Cameroun, un échantillonnage raisonné a permis de sélectionner 114 exploitants cacaoyers. L’approche à deux étapes recourant aux modèles Data Enveloppent Analysis (DEA) et Tobit censuré a permis d’analyser l’efficacité des exploitations.
This study examined the effect of sustainable intensification (SI) technologies, specifically the use of improved maize seed varieties, of improved bean seed varieties (Nua45), crop rotation, maize-legume intercropping and doubled-up legume systems on farm income in Dedza district, Malawi.
L’Afrique Subsaharienne n'a pas assez bénéficié des grandes révolutions connues du monde agricole qui ont permis d’accroitre les productivités. Malgré l’existence des nouvelles technologies, les niveaux des productivités agricoles demeurent faibles et inférieurs à ceux d’autres régions en développement.
The adoption of improved agricultural technologies is very low in Tanzania, which has led to both low crop productivity and low production. This paper therefore analyses the factors that influence the adoption of improved seeds, inorganic fertilisers and a package of technologies by smallholder maize farmers in Tanzania
This paper assesses the differences in technical efficiency of, and the cassava production systems employed by, male-managed (MMF) and female-managed (FMF) cassava farms in the Fanteakwa District of Ghana.
This study applied the zero-inefficiency stochastic frontier (ZISF) to analyse the technical efficiency of 333 improved rice-farming households for the 2012/2013 farming season in Ghana.
The main focus of this paper was to: (i) determine the impact of women’s share of household income on the pattern of expenditure on various categories of basic goods in southeast Nigeria; (ii) explain the pattern of household expenditure using the bargaining model of household behaviour; and (iii) extrapolate the results to the policy implications of gender-specific control of household incomes.
This article examines the current state of food safety preparedness and response in three representative countries in sub-Saharan Africa (SSA): Kenya, Senegal and South Africa. We focus on foodborne diseases associated with the microbial contamination of animal-sourced foods.
The hazards and impacts of climate change are exacerbating. They threaten crop productivity, farmers’ resilience and the mitigation of greenhouse gas (GHG) emissions. Understanding climate-smart agriculture (CSA) and applying it is crucial.
This continent-wide review of studies on price transmission implemented for the global, regional cross-border, within-country urban and within-country rural market segments provides a broad overview of current conditions in Sub-Saharan Africa food markets and provides insights into how market development varies across regions and crops.
Agricultural digitisation is one of the key drivers of agricultural development, as well as of rapid economic growth, in many countries. This study aims to investigate the causal links between agricultural digitisation and high-quality agricultural development in the context of developed and developing countries.
Agricultural price transmission across space and time: The case of cowpea and yam markets in Nigeria
The transmission of price changes to markets has attracted renewed interest since the international food price spikes of 2007 to 2011. In response to this, this paper investigates the long-run behaviour of Nigerian cowpeas and yam tuber retail prices across space and time from 2000 to 2015.
Does commercialisation drive technical efficiency improvements in Ethiopian subsistence agriculture?
The conditions in which increased market participation leads to improved technical efficiency are still not adequately understood. This study therefore investigated farmers’ market participation rates and their predicted technical efficiency scores by performing a two-stage least squares (2SLS) regression analysis using household-level data obtained from the 2009 Ethiopian rural household survey.
Fair trade is an important ethical concern in the food value chains of developed countries. However, there is a dearth of empirical insights into consumer preferences for this critical aspect in the domestic markets of developing countries.
Achieving state market policies depends partly on the extent to which changes in commodity prices are transmitted along supply chains. This paper examines the effect of the National Food Buffer Stock Company (NAFCO) on price transmission between white maize wholesale and retail markets in Kumasi, Ghana.
The impact of women’s empowerment in agriculture on women\s health, indicated by their body mass index (BMI), is examined using an instrumental variable estimation approach on a sample of 4 267 women.
The reintroduction of innovative forms of input subsidies in sub-Saharan Africa (SSA) following the food crisis of 2008 raises concerns about their effectiveness in the fight against poverty. In this context, this paper examines the effect of the targeted fertiliser subsidy implemented in Togo from 2017 to 2019.
Willingness-to-pay (WTP) studies for traditional food products are plausibly affected by unobserved decisions and strategic collusion between the experimenter and respondents. Similarly, WTP estimates in developing countries using a one-time survey might be inconsistent, as the acceptance of new products likely varies with exposure to product attributes.
This paper evaluates the extent to which changes in international wheat prices are transmitted to domestic markets in Kenya using an error correction model (ECM) that employs monthly producer price data for the period 2002 to 2020. 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.
Recognising potential selection bias due to non-randomness of the data, this study used propensity score matching on data from a nationally representative fifth Integrated Household Survey (IHS5) to investigate the effect of agriculture extension services on the technical efficiency of maize farmers in Malawi.
