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.
To enrich agriculture reform and reap its benefits, policy makers need to localise policy issues within and across their domestic zones. Using a stochastic meta-frontier function, this study analysed the production efficiency of the cassava subsector of cassava growers from Bomi and Nimba counties in Liberia.
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.
This paper evaluates output supply and input factor demands for livestock products in the Southern rangelands of Kenya. A flexible translog profit function that permits the application of the primal approach to the output supply and factor demand analysis was estimated using household-level data.
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.).
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.
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.
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 adoption of improved agricultural technologies is known to significantly improve incomes, create more wealth, alleviate poverty and contribute to rural development in many developing countries.
A new high-yielding upland rice variety known as New Rice for Africa (NERICA) has been recognised widely as a promising technology for addressing the food shortage and poverty problems in sub-Saharan Africa.
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.
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.
Soybean has been the world’s fastest growing crop over the last 15 years. Yet, as an untraditional and unfamiliar crop, soybean requires small farmers to move beyond their traditional production practices and marketing arrangements in order to produce a successful crop.
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.
Farm efficiency analysis provides significant insights into farms’ potential to enhance agricultural productivity. This article reports on an investigation of technology adoption and technical efficiency (TE) in the Ethiopian maize sector.
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.
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.
This study examines whether Liberian consumers are willing to pay for new, locally produced nutrient-dense rice, and if farmers are willing to grow such rice.
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.
This paper contributes to the expanding literature on multidimensional poverty and gender inequality in Tunisia by presenting an individual measure of multidimensional poverty.
The special issue focused on topics in environmental and resource economics that originated from the inaugural conference of the African Association of Environmental and Resource Economists (AFAERE), held on 2-4 August 2021.
This study examines how food prices and related seasonality factors affect the dietary choices of low-income farm households in rural Tanzania. The Kishapu and Mvomero districts were selected based on contrasting rainfall patterns, farming practices and economic activities.
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.
Since 2002, a range of South African policies have attempted to address the disproportionate burden of food and nutrition insecurity on the population. Yet malnutrition among the poor has worsened.
