The starting point for this article is the concept of a commodity exchange. A working definition is a physical or – more likely – electronic marketplace for buying, selling and trading commodities, whether ‘hard’ commodities, which typically are natural resources that must be mined or extracted (gold, rubber, oil, etc.), or ‘soft’ commodities, which are mainly agricultural products or livestock (coffee, corn, cotton, sugar, soybeans, etc.).

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 argues and provides empirical evidence that trade-offs and/or complementarities are inherent in technological options that shape the adoption of and land-use decisions in production systems involving multiple crops in Ethiopia.

Climate-smart agriculture (CSA) is viewed as a potentially effective intervention to address low agricultural productivity in Sub-Saharan Africa (SSA), while strengthening farmers’ capacity to adapt to the effects of climate change.

African animal trypanosomiasis (AAT) and its vectors, mainly tsetse, are a major constraint to livestock production in sub-Saharan Africa (SSA). Control efforts have been ongoing for decades, but finding a sustainable solution remains a major concern.

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.

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.

We measured the producer price impacts of food and cash transfer programmes in Ethiopia using monthly panel data from 37 zones in four major regions over the period January 2007 to December 2010.

Livestock, particularly cattle, are an integral part of livelihoods in rural sub-Saharan Africa. However, diseases such as African animal trypanosomosis (AAT) have limited the potential of this important sector in the rural household economy.

The high volatility of the world cocoa price makes the millions of African cocoa farmers highly vulnerable to poverty. A large volatility in the value of an agricultural commodity is linked to the inelasticity of its supply or demand.

In this paper, we explore the role of wildlife in climate change adaptation, especially in areas used predominantly for livestock production in South Africa. Using a sample of 3 449 wildlife and livestock ranches, we estimate a multinomial choice model of various ranching options in these areas. The results indicate that mixed wildlife-livestock ranches are less vulnerable to climate change when compared to ranches with only wildlife or only livestock.

Cette étude examine l'impact économique de l'utilisation des semences améliorées sur la sécurité alimentaire des ménages ruraux au Cameroun.

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 characterises the nature of the vegetable production shortfall throughout Ghana for remedial action to be taken. By applying the meta-stochastic frontier analysis to a sample of okra, pepper and tomato farmers, the results show that the ranking of production inputs in production is in the order land, hired labour, fertiliser, pesticide and family labour.

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.

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.

The adverse effects of weather extremes produce widespread damage and cause severe alterations in the normal functioning of household agricultural production in Zambia. Extreme weather events such as floods and drought are expected to increase in intensity and frequency due to climate change.

Despite the crucial role played by Nile perch in the income of fishers around Lake Victoria, Tanzania, fishing pressure has increased in recent years and has led to overfishing and, consequently, a risk to the lake’s future sustainability and the fishers’ livelihoods. This study used data collected in 2018 from 268 randomly selected sample fishers at 10 landing sites across Lake Victoria.

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.

The use of novel feed ingredients from aquaculture is growing globally. However, their contributions to scalable and sustainable aquafeed solutions are unclear. New ingredients for feeds are desired in the framework of sustainability and a circular economy; thus, initiatives for implementing such novel ingredients are of interest to agricultural practitioners.

We look at the prioritisation of agricultural value chains (VCs) for the allocation of R&D resources that maximise development outcomes (poverty, growth, jobs and diets) in Senegal.

The literature on what drives crop failure and crop abandonment is scant. This paper explores the interplay between risk factors and crop abandonment. We examine the role of risk sources and risk management strategies in crop abandonment by smallholder maize farmers in Zambia.

Agricultural commercialisation is a critical pathway for economic development in Sub-Saharan Africa (SSA). However, the lack of market information may impede this development. To the best of the authors’ knowledge, this is the first paper to examine market information and preferences for soybean quality in a developing-world context.

Cet article analyse le rôle du crédit et de l’éducation dans les différences de productivité du maïs entre femmes et hommes au Burkina Faso.
