Assessing the crop productivity and household welfare effects of adopting certified seeds of improved cassava varieties in Uganda
This article identifies the determinants, crop productivity, and household welfare impacts of adopting certified seeds of improved cassava varieties (c-ICVs) in Uganda. The determinants were identified using the two-part model while the crop productivity and household welfare impacts were assessed using the endogenous switching regression model. The data came from 609 farm households in Uganda’s three major cassava-growing regions (Eastern, North…
Elaborating institutional arrangements to better enhance sustainable crop intensification in Uganda
Covid-19 outbreak and rural household food security in the Western Democratic Republic of the Congo
Although global assessments of the initial impacts of the coronavirus disease (COVID-19) have focused on income, jobs, and health conditions, this study constitutes one of the first studies that assessed the impact of COVID-19 on food security in DRC and established the short-term implications of the COVID-19 outbreak on rural households' food security in DRC. In addition, the study recommendations contributed to shaping government interventions …
Gender differences in technology adoption and agricultural productivity
It is widely recognized that female farmers have considerably less access to productive assets and support services than male farmers. There is limited evidence of gender gaps in technology adoption and agricultural productivity after accounting for the differential access to factors of production between males and females. This study investigates the gender differences in the adoption of improved technologies and agricultural productivity in Mal…
The effects of foreign direct investment on youth unemployment in the Southern African Development Community
This paper examines the effect of foreign direct investment (FDI) on youth unemployment in the Southern African Development Community (SADC) region using panel data from the World Bank World Development Indicators for the period 1994–2017. Results from the Feasible Generalized Least Squares (FGLS-Parks) technique show that FDI has an insignificant effect on reducing youth unemployment in the SADC region. This could be because the type of FDI in t…
The poverty impacts of improved soybean technologies in Malawi
Improved soybean varieties and agronomic practices have been widely disseminated to smallholder farmers in Malawi over the last 15 years. However, there is no empirical evidence on the welfare impacts of adopting improved soybean technologies. This paper estimated the poverty impacts of adopting improved soybean technologies using data from 1,234 households in six soybean growing districts accounting for over 80% of the total soybean production i…
Factors influencing implementation of bylaws on sustainable crop intensification
The study examined the factors for the successful implementation of bylaws on sustainable crop intensification. The study used the new institutionalism theory to examine the implementation of bylaws in the potato cropping system in southwestern Uganda. A mixed model featuring both qualitative and quantitative approaches was used in the study. This involved analysis of primary data. The primary sources were key informants, focus group discussions,…
Does cooperative membership increase and accelerate agricultural technology adoption? Empirical evidence from Zambia
In developing countries, agricultural cooperatives are increasingly being used to promote improved agricultural technologies and alleviate food insecurity and poverty. However, little is known about the role of agricultural cooperatives in accelerating the adoption of improved agricultural technologies. Using a comprehensive balanced household panel and varietal data, this study applied the difference-in-difference model to identify factors affec…
Misperceived quality
Hard work and hazard
An emerging orthodoxy supports the proposition that the rural economy - built around agriculture but encompassing much more - will serve as sweet spot of employment opportunities for many millions of young people into the foreseeable future. However, our understanding of how rural young people in Africa take advantage of processes of rural transformation or engage with the rural economy is limited. Drawing on qualitative research conducted with 1…
Agricultural technology adoption and household welfare
Previous studies on the adoption and impacts of improved crop varieties have relied on self-reported adoption status of the surveyed households. However, in the presence of weak variety maintenance and poorly functioning seed certification system, measurement errors in self-reported adoption status can be considerable. This paper investigates how such measurement errors can lead to biased welfare estimates. Using DNA-fingerprinting based varietal…
The poverty impacts of improved cowpea varieties in Nigeria
Adoption of improved agricultural technologies has long been recognized as critical for reducing poverty through increased productivity, incomes, and asset accumulation. Using a nationally representative survey data from a sample of over 1500 households in Nigeria, this paper evaluates the impacts of adoption of improved cowpea varieties on income and asset poverty reduction using an endogenous switching regression model. The results showed that …

The Rapid Degradation of Lambda-Cyhalothrin Makes Treated Vegetables Relatively Safe for Consumption
Lambda-cyhalothrin (λ-cyhalothrin) is the most commonly used pyrethroid insecticide for vegetable farming in Benin. This insecticide is misused and overused by farmers, and hence may pose health hazards to consumers. We monitored λ-cyhalothrin residues in lettuce and cabbage from farms at the market gates in Cotonou and Parakou using high performance liquid chromatography (HPLC) analysis techniques. These residues were also monitored on samples d…
Patterns and structure of household income inequality in rural Ethiopia
Who benefits from which agricultural research-for-development technologies? Evidence from farm household poverty analysis in Central Africa
Impacts of extension access and cooperative membership on technology adoption and household welfare
This paper examines the impacts of access to extension services and cooperative membership on technology adoption, asset ownership and poverty using household-level data from rural Nigeria. Using different matching techniques and endogenous switching regression approach, we find that both extension access and cooperative membership have a positive and statistically significant effect on technology adoption and household welfare. Moreover, we find…
Productivity and Welfare Effects of Nigeria's e-Voucher-Based Input Subsidy Program
In an attempt to go beyond the so called " smart " subsidies, Nigeria has embarked on a potentially innovative mobile phone-based input subsidy program that provides fertilizer and improved seed subsidies through electronic vouchers. In this article, we examined the productivity and welfare effects of the program using household-level data from rural Nigeria. The article employed instrumental variable regression approach to control for the potent…

Engaging with cultural practices in ways that benefit women in northern Nigeria
This study explores the intra-household impact of improved dual-purpose cowpea (IDPC) from\na gender perspective, in terms of productivity and food, fodder, and income availability, the\nimpact of which is linked to the income thus placed in the women’s hands. Surplus income is\nimportant in providing food and nutritional benefits to the home, particularly during periods\nof risk. More importantly, income generated through the adoption of improve…
