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.

Using an original database from French archives on French trade statistics, this article undertakes a comprehensive study of the nature and dynamic of French sectoral trade for the period 1880 to 1912.

This study examines the complementarity and substitutability effect of private investment and public expenditure on agricultural productivity in Nigeria for the period 1978 to 2018. The study employs the vector error correction modelling (VECM) technique, and the estimate shows that government expenditure on the agricultural sector had the most significant effect on agricultural productivity, followed by commercial bank credit for the agricultural sector.

Smallholder rural farmers are exposed to diverse idiosyncratic and covariate shocks that lead to high income and consumption volatility. Formal cash management tools, which are important for managing risk and volatility, often break down due to high information asymmetries and the transaction costs of operating in rural areas.

Mali’s population is experiencing lifestyle and dietary changes that are driven in part by urbanisation and income growth. Utilising two large-scale datasets, we bring new empirical evidence regarding whether Malians are shifting toward highly processed foods, meals purchased away from home, and sugary foods.

This study seeks to identify the internal and external factors determining Ethiopia’s bilateral exports and total trade flows. It uses panel data covering 21 major trading partners of Ethiopia from 2000 to 2017 and estimates an augmented fixed effects gravity model.

This study analysed the long- and short-run effect of economic policy uncertainty on agricultural growth in Nigeria. Annual data was collected from secondary sources and analysed using the autoregressive distributed lag (ARDL) model and the associated bounds test.

Three experiments were conducted from 2014 to 2018 to examine the economics of yellow passion fruit production under different soil fertility management. In 2014, two yellow passion fruit genotypes, that is Conventional and KPF 4, were grown in the field and pot simultaneously under varying rates of poultry manure (PM), including 0, 10, 20, 30 and 40 t/ha.

This paper conducts ex-ante impact assessments for policy interventions to promote amaranth value chains in Tanzania and Kenya. Amaranth is an underdeveloped, drought-resistant, and nutrition-rich crop used for human food, animal fodder, and ornamental purposes.

The effects of climate change on smallholder agriculture under different crop technologies, namely conservation agriculture, Falbedia albida, optimal fertilisation and intensive farming, were analysed against the conventional subsistence farming in Malawi.

Our understanding of climate-induced crop failure and crop abandonment is limited at present. This study surveyed theoretical and empirical literature on climate-induced crop failure and crop abandonment.

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 examines determinants of the adoption of rainwater-harvesting technologies in a rain shadow area of southern Malawi. The most common ex situ technologies in the area were dams, and the widely used in situ technologies were box ridges, contour markers and swales.

There is an emerging body of studies assessing the influence of resilience on household food security in developing countries. Yet no study has systematically analysed this theme in Zimbabwe, an area that we address.

A partial equilibrium model was used to estimate the impact of a free trade agreement within ECOWAS on imports by Nigeria, based on trade data prior to implementation in 2015.

Baobab products provide cash income and supplement diets for local communities living in marginalised, arid and semi-arid regions. However, these products are neglected by research, selectively traded and considered underutilised. This study endeavours to narrow this information gap by analysing the determinants of baobab collectors’ choice of marketing channels in Kenya.

With increasing recognition holding the promise of overcoming the outstanding problems faced by African agriculture, IAR4D faces the danger of being ‘blurred’ by past approaches and falling short of its potential to deliver the desired impacts in diverse multi-stakeholder, biophysical, socioAfJARE economic, cultural, technological and market contexts unless its actualisation and working is clearly understood.

This study analyses the trade-offs between welfare (measured by income) and greenhouse gas (GHG) emissions using a farm-level optimisation model that incorporates the predominant cereal (sorghum), legumes (groundnut, soybeans), livestock (cattle, goats and sheep) and trees (locust bean, camel’s foot) representative of production systems at two contrasting sites in northern Nigeria.

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 study evaluated the effect of agriculture, industry, manufacturing and the service sector on economic growth for the period 1991 to 2020 using the autoregressive distributed lag stationarity (ARDL) bounds-testing approach.

L’intégration des marchés est un élément clé pour comprendre la transmission des prix entre les marchés et maîtriser les équilibres (les efficiences). Cependant, certains facteurs peuvent entraver l’atteinte de cette efficience.

Conservation agriculture is promoted as a green technology that enhances the productivity and food security of farmers. However, there is limited evidence from practising farmers regarding these expected outcomes.

The inverse farm size and productivity relationship (IR) is a recurring theme in the literature. However, most previous studies were undertaken within a setting of mixed cropping systems. In this article, we investigate the effect of farm size on productivity within the context of a perennial mono-cropping system, acute competition for farmland, frequent subdivision of farms and declining yields.

The study employed the Phillips and Sul log-t convergence test to analyse the degree of convergence for the Niger Basin region (NBR) countries in terms of per capita carbon emission and food availability. We found that, between the years 1986 and 2020, the Niger Basin region produced 13.5% less food per person than it did during the base period of 2004 to 2006.
