Private sector promotion of agricultural technologies: Experimental evidence from Nigeria

Private sector promotion of agricultural technologies: Experimental evidence from Nigeria

Private sector agricultural businesses are critical for scaling new and potentially environmentally-friendly technologies, though much attention has focused on public agricultural investment. Working with a private firm, we conduct an experiment testing the effectiveness of alternative marketing strategies for promoting the adoption of urea super granule fertilizer (USG) among rice farmers in Nigeria. We disentangle the effects of price discount vouchers and the firm’s standard marketing package. We find that the firm’s standard marketing increases the adoption of USG fertilizer by 24 percentage points while reducing prilled urea utilization by 17 percentage points. Discount vouchers increase adoption of USG by an additional eight percentage points, but are not profitable for the firm. Although the adoption of USG leads to substantial environmental benefits by reducing nitrogen loss, farmer rice yields did not increase. Thus, despite the potential public benefits, private incentives facing firms and farmers are insufficient to drive scaling after a one-year intervention.

Herder-related violence, labor allocation, and the gendered response of agricultural households

Herder-related violence, labor allocation, and the gendered response of agricultural households

Violent conflict between nomadic herders and settled agricultural communities in Nigeria occurs as both groups clash over the use of land and natural resources, in part, due to a changing climate. We generate theory and evidence to study the labor responses of individuals within agricultural households to herder-related violence and consider a “shadow of violence” mechanism, whereby previous exposure to a violent event alters labor responses to a recent event. Using panel data from 2010 through 2019, we highlight how exposure to violence can lead to differing responses in the planting or harvest seasons and among men or women. In the planting season, among both men and women living in households with no previous exposure to herder-related violence, we find that exposure (i.e., singular exposure) leads to a reduction in household enterprise work, but among households with previous exposure experience, exposure (i.e., repeated exposure) leads to an increase in household enterprise work. Meanwhile, repeated exposure to herder-related violence reduces agricultural work among men only. This leads total hours worked to decline in response to singular exposure and to increase in response to repeated exposure especially among women. In the harvest season, we find that singular exposure increases agricultural work among both men and women, but repeated exposure reduces agricultural work among men only.

2021 Social Accounting Matrix for Nigeria

The 2021 Nigeria Social Accounting Matrix (SAM) follows IFPRI’s Standard Nexus SAM approach, by focusing on consistency, comparability, and transparency of data. The Nexus SAMs available on IFPRI’s website separates domestic production into 42 activities. Factors are disaggregated into labor, agricultural land, and capital, with labor further disaggregated across three education-based categories. The household account is divided into 10 representative household groups: Rural and urban households across per capita consumption quintiles. Nexus SAMs support the improvement of model-based research and policy analysis in developing countries and allow for more robust cross-country comparisons of national economic structures, especially agriculture-food systems.

Food Security Simulator — Nigeria

2023Comstock, Andrew R.; Ecker, Olivier; Pauw, Karl; Thurlow, James
Details

Food Security Simulator — Nigeria

The Food Security Simulator is an innovative and easy-to-use, MS-Excel-based tool for assessing the potential short-term impacts of food price or household income shocks on food security and people’s diets. The Simulator is an ideal tool for first-cut forward-looking evaluations of direct, household-level outcomes of economic crises and policy responses in a timely manner. The tool allows users to enter positive and negative price or income changes in percentage terms and provides simulated changes for a diverse set of food-consumption- and diet-quality-related indicators. In addition to detailed tabular presentations of all simulation results by household income quintile and residential area, key indicator results are summarized in concise overview tables and visualized in graphs for easy export and use in reports. The underlying data include estimates from representative household survey data and rigorous, sophisticated food demand models to capture consumer behavior.
