Background and motivation
Timely access to quality seed, among other factors, determines household planting decisions and has implications for agricultural productivity. Hence, it is important to understand where and how small-scale producers (SSP) obtain their seed. To answer this question, we use nationally representative agricultural households survey data from the Living Standards and Measurement Study – Integrated Surveys on Agriculture (LSMS – ISA) data for the Ethiopia Socioeconomic Survey or ESS and the Nigeria General Household Survey or GHS.
What are the main household seed sources?
The World Bank LSMS – ISA project, in partnership with countries’ national statistical offices and funders such as the Bill & Melinda Gates Foundation (BMGF), has been collecting rich panel survey data that can be used to analyze[i] seed sources over five waves for Ethiopia and four for Nigeria.
The surveys ask farmers to report crops planted and for each crop the type of seed -traditional or local vs improved or hybrid – and where the seed was acquired – purchased, leftover or home saved seed, and seed received for free. We further disaggregate purchased seed by type of seller: relative or friend or neighbor, village head, market or traders, government, or others.
What are the main sources of seed for rural households in Ethiopia and Nigeria?
Figures 1 and 2 show the trend in the percentage of rural farm households reporting using seed from different sources for Ethiopia and Nigeria. The results show that in general, a higher percentage of rural households use home saved or leftover seed relative to purchased seed. However, over the past decade the use of purchased seed is rising and home saved, or leftover seed is declining. In Ethiopia, the percentage of rural households reporting purchasing seed rose from a low in 2015 (Figure 1), and in Nigeria, after 2012 (Figure 2). On average, a higher percentage of rural households in Ethiopia use purchased seed than those in Nigeria. This notable growth in the use of purchased seeds in Ethiopia has been partly attributed to seed producer cooperatives that have improved the supply of seeds in the country. The results also show that in both countries, between 5 and 20 percent use seed received for free from other farmers or NGO or the government.
What is the share of seed from the main sources for rural households in Ethiopia and Nigeria?
The share of seed used by a household from each source is calculated as the quantity of seed from that source (purchased, saved/leftover or free) divided by the household’s total quantity of seed from the three sources. In Ethiopia, the share of purchased seed rose rapidly from 2015 – 2021 to exceed 50 percent. In Nigeria, the share of purchased seed rose in the last two waves to 27 percent in 2018.
Are there any gender differences in the share of seed used from the different sources by farm households in Ethiopia and Nigeria?
The share of purchased seed used by male headed households in Ethiopia between 2011 – 2015 was marginally higher than that of their female counterparts, with the trend reversing between 2015 – 2021 (Figure 5). In Nigeria, the share of purchased seed used by male headed households is generally lower than that of their female counterparts (Figure 6) except for 2018. This result is in line with the findings of a 2015 study showing that male headed households use less purchased seed than their male counterparts.

Concluding remarks
The descriptive results presented above generally show that rural farm households in Ethiopia and Nigeria predominantly use home saved or leftover seed. However, over the past decade, the use of market purchased seed, especially of legumes and nuts and horticultural crops, has been growing. Given that improved varieties tend to be market-sourced, this trend may show up in productivity numbers, though climate change remains an unpredictable factor.
