“Nigeria: Recent developments in agricultural research”

After a period of stagnation in the late-1980s and early 1990s, investments in Nigeria’s public agricultural R&D increased substantially around the turn of the millennium. Adjusted for inflation, investments doubled from 12 million naira in 2000 to 24 million in 2008 (in 2005 prices). This growth included increased researcher salaries and substantial investments for the >> Read more

“Strengthening innovation capacity of Nigerian agricultural research organizations”

Strong agricultural research and development (R&D) is crucial for improving agricultural productivity and efficiency, which in turn both lead to agricultural development, food security, and poverty reduction. However, several studies have shown that in many developing countries, in particular in sub-Saharan Africa, there is persistent underinvestment in R&D and weak research capacity, both of which >> Read more

“Asset dynamics in Northern Nigeria”

This paper examines household asset dynamics and gender-differentiated asset inequality over a 20-year period (1988–2008) in northern Nigeria. We show that the initial endowments of both household capital and livestock holdings are inconsistent with the poverty trap hypothesis but that tracking rules for households in panel surveys may lead to differences in empirical results on >> Read more

“From the ground up: Impacts of a pro-poor community-driven development project in Nigeria”

The community-driven development (CDD) approach has become increasingly popular because of its potential to develop projects that are sustainable, are responsive to local priorities, empower communities, and more effectively target poor and vulnerable groups. The purpose of this study is to assess the impacts of Fadama II, which is a CDD project and the largest >> Read more

“Market and climatic risks and farmers’ investment in productive assets under the Second Fadama Development Project in Nigeria”

The majority of African farmers lack the means to mitigate the impact of risks such as those associated with rainfall and commodity prices. Because most farmers in Sub-Saharan Africa are risk-averse, they may be willing to invest in productive assets that can mitigate the impacts of such risks if their capital constraints are relaxed through >> Read more

“Qualitative risk assessment on the transmission of HPAI (H5N1) virus: From backyard and medium-scale commercial farms to household free-range poultry in Nigeria”

The Nigerian poultry industry, comprising both commercial and rural poultry systems, experienced the first highly pathogenic avian influenza (HPAI) H5N1 outbreak in 2006. This industry provides an affordable source of protein to millions of Nigerians through poultry eggs and meat. The rural poultry production system is essential in poverty alleviation, food security and the promotion >> Read more

“Constraints to fertilizer use in Nigeria”

Fertilizer consumption rates in Nigeria remains among the lowest in the world despite decades of aggressive subsidization. The extension service in Nigeria has a double-edged impact on fertilizer use in the country; not only can their activities increase farmers’ demand for fertilizer, but also the organizational framework of the service, Agricultural Development Programs, is the >> Read more

“Migratory responses to agricultural risk in Northern Nigeria”

We investigate the extent in which northern Nigerian households engage in internal migration to insure against ex ante and ex post agricultural risk due to weather-related variability and shocks. We use data on the migration patterns of individuals over a 20-year period and temperature degree-days to identify agricultural risk. Controlling for ex ante and ex >> Read more

“Mapping the policy process in Nigeria: Examining linkages between research and policy”

How research contributes to the policy process in developing countries in general, and in Nigeria more specifically, is not well understood. Yet such understanding is a critical part of doing effective policy research. This has become especially critical for the International Food Policy Research Institute (IFPRI), which has set up a country office for policy >> Read more

“Economywide impact of avian flu in Nigeria: A dynamic CGE model analysis”

Since its emergence in Africa in 2006, the highly pathogenic avian influenza (HPAI) virus of the H5N1 subtype has spread rapidly to poultry farms in several countries, including Burkina Faso, Cameroon, Ghana, Niger, and Nigeria (FAO 2006; OIE 2006). In February 2006, Kaduna state in Nigeria was the first of 36 states to report the >> Read more

“Patterns and trends of child and maternal nutrition inequalities in Nigeria”

Despite the fact that nonincome dimensions of well-being such as nutrition and health are now placed on the global development agenda, substantial gaps remain in our knowledge about patterns and trends in nutrition inequalities in many developing countries. The main objective of this paper is to document a useful starting point for understanding the determinants >> Read more

“Agricultural growth and investment options for poverty reduction in Nigeria”

This study uses an economy-wide, dynamic computable general equilibrium (DCGE) model to analyze the ability of growth in various agricultural subsectors to accelerate overall economic growth and reduce poverty in Nigeria over the next years (2009-17). In addition, econometric methods are used to assess growth requirements in agricultural public spending and the relationship between public >> Read more

“Rural non-farm income and inequality in Nigeria”

This paper investigates the contribution of rural non-farm income to income inequality by examining the contribution of specific income sources (farm income from irrigated agriculture, farm income from rainfed agriculture and non-farm income) to income inequality in Nigeria. The results reveal the relative importance of specific income sources to income inequality and the various determinants >> Read more

“Estimating the impact of agricultural technology on poverty reduction in rural Nigeria”

It has often been argued that new agricultural technologies lead to poverty reduction. This paper argues that any changes in poverty situation attributed to those who adopt new agricultural technology (treatment group) without a counterfactual comparison of carefully selected nonadopters (control group) are likely to be questionable. The paper estimates the effects of new agricultural >> Read more

“Investigating the potential Impact of HPAI on Livelihoods in Nigeria”

Small-scale poultry production is an integral part of livelihoods in Nigeria, contributing to households’ income, food and nutrition security, and gender equality (Kushi et al. 1998; Houndonougbo 2005; Obi et al. 2008). Almost 60 percent of Nigeria’s 150 million poultry population is managed by household level poultry producers, in semi-commercial and non-commercial, small-scale, backyard, or >> Read more
