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.

Empirical studies on the effects of governance structures on incentives have still received little attention in the wheat value chain research of developing countries. The purpose of this paper is to investigate the effects of governance structures on actors’ incentives in different functional nodes of the wheat value chain.

Using a non-experimental cross-sectional dataset of 471 households, we evaluate the impacts of satellite collection points (SCPs) under the Purchase for Progress (P4P) initiative implemented by the World Food Programme (WFP) on storage decisions and crop income from maize sales among smallholder farmers in Uganda.

This paper examines rice trade flows within and across regions in Madagascar, based on data of unique rice sales collected in 22 major markets in Madagascar in 2012 and 2013.

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.

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.

This study investigated the food security effect of the adoption of improved maize varieties among farming households in Uganda using four waves of the Uganda National Panel Survey (UNPS) spanning the period 2013 to 2020.

Limited access to timely and adequate information has been identified as a major hindrance to smallholder agriculture in most parts of sub-Saharan Africa. This has negatively affected the socio-economic welfare of smallholder farmers, resulting in high numbers of food insecure households.

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.

The recent increase in farmland investments in developing countries by private equity funds, large multinationals and sometimes foreign governments has attracted widespread attention and strong emotions from various interest groups.

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.

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.

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.

Rural areas across the developing countries in every region of the world lag behind their urban counterparts in many important sectors and, most importantly, in improved water supply services.

Vitamin A deficiency is still a challenge in many African countries, including Tanzania. Survey data were gathered in Tanzania to determine consumers’ risk perceptions of vitamin A deficiency (VAD) and severe visual impairment.

Building up resilience in agricultural households has assumed a critical role in development strategies in recent years because, it is argued, the costs of strengthening resilience are less than the recurring expenditure for disaster assistance.

Accessing water supply services remains a serious challenge in Wakiso District in Uganda, where most households travel long distances to collect water – a process that threatens their health, productivity and economic wellbeing.

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.

Variability in climate and debility in soil fertility affect agrarian production, especially in sub-Saharan Africa, and thus threaten food security. This has prompted the seed sector to introduce various varieties of climate-smart maize in Kenya and release them in the market. In contrast, there is little experiential insight into how the adoption of these varieties by small-scale farmers affects their household income.

This study uses an online laboratory experiment and a post-experimental survey to test whether the Mastercard Foundation (MCF) scholarship programme causally influences the creation of cognitive social capital among University of Pretoria recipients.

This paper analyses the impact of adaptation to climate change on bean productivity on a micro-scale using instrumental variable techniques in a two-stage econometric model, using data collected from farming households in northern and central Uganda.

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.

This article investigated the role of cattle attributes in buyers’ choices and hedonic pricing in Benin. Cross-sectional data were collected on 347 market cattle transactions using the revealed preference method.

Zimbabwe has set poverty reduction targets in a changing climate, yet the implications of climate variability for poverty remain under-explored.
