Disentangling Climate and Human Drivers of Land Degradation in East and Southern Africa
Timely monitoring of land degradation (LD) is essential to guide targeting the sustainable land management (SLM) practices to the suitable context that assists in achieving an LD neutral world. This study applied a 40‐year time series of remote sensing data representing vegetation indices and rainfall to identify the hotspots for the climatic and human‐induced LD or improvements in the East and Southern Africa (ESA) region. This was complemented …
Beyond average
Assessing the benefits of adopting climate-resilient farming technologies without considering the heterogeneity among farmers, may not provide a sufficient evidence base for policy. Yet, most empirical studies do not go beyond documenting the average effects of climate-resilient technologies. Using farm household survey data from Nigeria, this paper examines whether and to what extent the yield and income impacts of adopting drought-tolerant maiz…
Assessing the speed of improved postharvest technology adoption in Tanzania
The Purdue Improved Crop Storage (PICS) bag is often associated with preventing grain damage from insect infestation, reducing aflatoxin accumulation in stored grain, and avoiding exposure to hazardous storage chemicals. However, limited knowledge is available on the information channels driving the adoption of the technology. Using data from 429 households, this study examines the impacts of social learning and extension services on the speed of…

Do youth farmers benefit from participating in contract farming? Evidence from French beans youth farmers in Arusha, Tanzania
Contract farming (CF) is often seen as a system that enhances production efficiency leading to increased agricultural productivity and improved farmer livelihoods. However, there is a conflict in the literature on its impact on young farmers who are involved in farming in Sub-Saharan Africa. This paper evaluates the impacts of CF on crop yield, crop and household income among the youth farmers involved in French bean farming in Tanzania using cro…
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…
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…
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 productivity and income effects of adoption of improved soybean varieties and agronomic practices in Malawi
Adoption and welfare impacts of multiple agricultural technologies
Using plot level panel data and multinomial endogenous switching regression, this article analyzes the adoption and welfare impacts of multiple agricultural technologies in eastern Zambia. We adapt a multinomial endogenous switching/treatment effect regression framework to correct for selection bias and endogeneity originating from both observed and unobserved heterogeneity. Results indicate that joint adoption of multiple agricultural technologi…
Adoption and Impacts of Sustainable Agricultural Practices on Maize Yields and Incomes
This paper uses a multinomial endogenous treatment effects model and data from a sample of over 800 households and 3,000 plots to assess the determinants and impacts of adoption of sustainable agricultural practices (SAPs) on maize yields and household incomes in rural Zambia. Results show that adoption decisions are driven by household and plot level characteristics and that the adoption of a combination of SAPs raises both maize yields and inco…
