Land tenure security, crop choices, and agricultural input investment decisions: Evidence from nationally representative data in Nigeria

Land tenure security is widely regarded as essential for agricultural investment and productivity growth. However, causal evidence on its effects across multiple farm decisions remains limited, particularly in sub-Saharan Africa. This study investigates how tenure security is associated with crop portfolio choices and input investment decisions among smallholder farmers in rural Nigeria. It measures tenure security using a composite index, drawn from wave 5 of the Nigeria Living Standards Measurement Study-Integrated Surveys on Agriculture (LSMS-ISA), that captures plot-level perceived security of ownership, and household reported risk of land loss, ownership security, and duration of ownership. The study employs two complementary approaches: a multivariate probit model to capture the joint and correlated nature of crop adoption decisions, and limited information maximum likelihood instrumental variables (LIML-IV) estimation to establish association between land tenure and input investment decisions. Results reveal significant but heterogeneous effects. Greater tenure security increases the probability of cultivating grains and cereals by 29.8 percentage points, while reducing the likelihood of growing legumes and pulses by 24.6 percentage points and horticulture by 11.4 percentage points respectively, which suggests a substitution effect toward grain specialization. On input investments, LIML-IV estimates indicate that a one-unit increase in the tenure security index raises organic fertilizer use by 9.93 percent, inorganic fertilizer use by 6.57 percent, and pesticide use by approximately 0.89 percent. These findings are robust to Lewbel’s heteroskedasticity-based identification strategy. Heterogeneity analysis reveals stronger investment effects among youth-headed households, while impacts on female-managed plots are statistically insignificant, pointing to persistent gender barriers. The study highlights the need for integrated policies that combine tenure formalization with crop diversification support, gender- and youth-sensitive land governance, and input market development in order to maximize the productivity gains from land rights reform in Nigeria.

Gender asset-ownership gap, women’s agency, and its implications for household inequality: Evidence from Nigeria

he gender asset-ownership gap remains a persistent barrier to inclusive economic growth. While women contribute significantly to agricultural production and household welfare, they continue to face constraints in accessing and controlling productive assets such as land and non-land resources. Using nationally representative panel data from the Nigeria Living Standards Measurement Study-Integrated Surveys on Agriculture (LSMS-ISA) waves 4 and 5, this study examines the role of women’s productive asset ownership and empowerment in shaping household income inequality in rural Nigeria. Descriptive evidence shows persistently high intrahousehold inequality, with intrahousehold Gini coefficients averaging approximately 0.70 across survey rounds, despite a modest decline between 2018/19 and 2023/24. Regional patterns reveal particularly pronounced inequality in the North East, where income distributions are heavily skewed and most households exhibit extreme intrahousehold disparities. Employing fixed effects regressions and Blinder-Oaxaca decompositions, the analysis yields three key findings. First, women’s land share is associated with reduced intrahousehold income inequality, but this effect is modest and conditional. It becomes meaningful primarily in households where women control more than half of total household farmland, suggesting that small and fragmented landholdings offer limited inequality-reducing potential on their own. Women’s control over income and participation in agricultural decision-making emerge as additional and consistently significant drivers of reduced intrahousehold inequality. Second, women’s land share has a significant and positive effect on women’s income share, with a 10 percentage point increase in female-managed farmland associated with approximately a 0.76 percentage point increase in women’s share of household income; women’s income control and agricultural decision-making further amplify this effect. Third, Blinder-Oaxaca decompositions reveal that households where women own productive assets have significantly lower intrahousehold inequality and higher women’s income shares than those where no woman owns an asset, with differences driven primarily by disparities in women’s income control and decision-making authority rather than asset ownership alone. This shifts the policy debate from simply closing gender asset gaps to ensuring women’s assets are productive and consolidated with genuine economic agency.

Financial inclusion for youth in agrifood systems: Gendered barriers and solutions in northern Nigeria

Financial inclusion for youth in agrifood systems: Gendered barriers and solutions in northern Nigeria

Nigeria is home to one of the world’s largest and fastest-growing youth populations aged 15–35, yet financial exclusion continues to sideline young people, particularly young women, from fully participating in agrifood systems. When women control financial resources, they generate multiplier effects across the food system. In northern Nigeria, where more than half the population remains unbanked, the stakes are especially high. This research note draws on evidence from two complementary IFPRI studies to examine the financial inclusion experiences of young women and young men in northern Nigeria and identify practical, gender-sensitive solutions.
