abstract = {The Russo-Ukrainian war has shocked global food prices and supply chains. Some of the largest impacts are expected in food-importing African countries. This includes Nigeria, where a combination of increasing population, urbanization, and declining domestic production increased households’ exposure to global price shocks. To understand how food demand responds to price shocks, we estimate household-level demand elasticities for selected food categories using the Exact Affine Stone Index (EASI) demand model. We simulate the effect of increasing grain and edible oil prices on demand by households across several food groups and items. Our results vary across regional and income groups and often differ because grains and edible oils represent different proportions of the respective sub-national budget shares. We find that, given their low price elasticity, a shock to the price of edible oils generally leads to changes to the household budget share. We also find that the war is expected to have the highest impact on non-grain starches and vegetable proteins, which had the highest own-price elasticities. Nevertheless, given that palm and groundnut oil are the dominant edible oils in Nigeria, the effects of the war depend on the elasticity of substitution between sunflower and these two oils on the global markets, as well as between edible oils and other foods. One policy implication of the study is the need for targeted food and nutrition interventions in response to crises or global price shocks, given the substantial sub-national variation in observed food budget shares, and in the effects of price shocks.},

abstract = {Attempts to ensure safety and quality control in the Day-Old Chicks (DOCs) value chain in Nigeria have been perceived to involve some duplicity/multiplicity of roles and/ or responsibilities, putting undue burden on the actors. Therefore, experts’ workshop on the DOCs value chain in Oyo State was implemented by the Innovation Lab for Policy Leadership in Agriculture and Food Security (PiLAF) to provide a guide for agenda setting for building a better industry. The workshop had the dual purpose of (i) undertaking a situational analysis of the DOCs value chain in Oyo State, Nigeria, and (ii) strengthening the policy process to effectively respond to the needs of the DOCs value chain in the state through clearly defined, unambiguous regulations and regulatory processes. Twenty-four experts comprising major actors along the DOCs value chain in Oyo State participated in the workshop. Using brainstorming and consensus building process, participants identified infrastructure and markets (strengths), weak regulatory control and high operating cost (weaknesses); supply gap, and good return on investment (opportunities); including adulteration and sharp practices (threats) as the most important Strength, Weakness, Opportunities and Threats (SWOT) factors influencing or capable of affecting the DOCs industry in the state. The DOCs value chain operators identified National Institute of Animal Science (NIAS) followed by the Veterinary Council of Nigeria as the most visible operators in the DOCs value chain. However, the operators perceived the activities of the regulatory bodies as more geared toward revenue generation than actually enforcing compliance to standard practices in the industry. The value chain actors affirm there are overlaps in some aspects of policy guidelines for the DOCs value chain by the Veterinary Council of Nigeria and NIAS leading to what may be described as double taxation to the disadvantage of the actors. Specifically, registration and licensing, prohibition, and import and export domains are some of the aspects of the policy documents that need some minor modifications for clarity and separation of roles.},

abstract = {This study examined the awareness and perception of agricultural policies by maize farmers in Oyo and Kaduna States of Nigeria. A multistage sampling procedure was used to select 424 respondents: 210 farmers from Oyo and 214 farmers from Kaduna, from whom data were collected using questionnaires administered through a phone poll. Mean, frequency and inferential statistics such as Chi-square, Spearman Rho, and Pearson Correlation were used to analyse the data. The findings revealed that farmers in Oyo (67.6%) and Kaduna (68.7%) States were aware of the ban on maize importation. Moreover, farmers in Kaduna were more aware (63.1%) of the Growth Enhancement Support Scheme than those in Oyo (48.1%). Most farmers in Oyo and Kaduna States had a favourable perception of the ban on maize importation. Farmers in Kaduna had a better perception of the Anchor Borrowers’ Program and Growth Enhancement Support Scheme than their Oyo counterparts. The study recommends that Agricultural policies in Nigeria should be co-created with farmers and decentralised to have holistic and encompassing policies workable nationwide.},

abstract = {Access to sources of cooking energy has potential impacts on food security, however, there is a paucity of information and empirical evidence on their linkages. This study sought to ascertain the impacts of access to cooking energy on household food security in Nigeria, using the nationally representative Living Standards Measurement Study data. The data covered the period 2010/2011 to 2015/2016. The Household Dietary Diversity Score (HDDS), and the Household Food Insecurity Access Scale (HFIAS) were used to measure household food security, while the major cooking fuel type utilized by households was used as a proxy for cooking energy access. To unravel the effects of access to different cooking energy sources on food security, inferential analysis was conducted using the Generalized Estimating Equations (GEE). The findings of the study revealed that traditional/biomass (firewood, grass and charcoal) cooking energy sources are still widely used by households across Nigeria. The empirical analysis showed that households that use transition and clean cooking energy sources were eating more diverse diets than those that use biomass. Furthermore, households using clean cooking energy sources had lower HFIAS than those using biomass. It is imperative that more households in Nigeria should have improved access to cleaner sources of cooking energy to reduce carbon emissions and enhance health outcomes, and food and nutrition status. This will significantly improve the national food security outlook, and foster the attainment of national and SDG (2 and 7) goals.},

abstract = {Climate change (CC) has been a threat to achieving zero hunger and a sustainable food system globally. While this problem is expected to persist for years to come, climate-smart agriculture (CSA) is being promoted as a measure to guarantee its end. Although, CSA has three pillars – mitigation, adaptation and food security; adaptation is most advocated in developing countries like Nigeria given the most devastating effects of CC in this region of the world. To comprehend the trends and eco-specific narratives around CSA in Nigeria, the study reviewed the literature on climatic scenarios and adaptation strategies by food crop farmers across the nine major agroecological zones, with insight from the last four waves (2010/2011, 2012/2013; 2015/16 and 2018/19) of the Living-Standard Measurement Study - Integrated Survey on Agriculture (LSMS-ISA). The data was analysed using descriptive statistics such as frequencies, tables and percentages. While the differences in means of yield across the agroecological zones, for all four waves, were determined using the analysis of variance (ANOVA). Although CC manifests in the form of consistent dry spells, unpredictable weather patterns and increased erosions across the agroecological zones, they differ in intensity and frequency. Farmers had adopted different CC adaptation options as a strategy for improving agricultural productivity of food crops, and enhancing crop resilience. However, many of these practices fall short of the expected CSA standard, given established climatic patterns over the last decade. An institutional framework that sufficiently addresses the needs of different agroecological contexts is required for an effective, and sustainable food system.},

abstract = {This study investigated stakeholders’ perspectives on the effect of government policies on the poultry subsector in Nigeria. Information was obtained from 17 stakeholders across various poultry-related value chains. The implications of government policies on the poultry subsector in Nigeria were explored through in-depth interviews with each stakeholder. A semi-structured interview guide, tape recorder was used to collect data. Content and thematic analyses were used to analyse the data with the aid of Atlas.ti software. Issues emerging from the ban of maize importation according to stakeholders were attitudinal change and sensitization (1:31), quality of local content (1:32, 1:14), production issues (1:13, 1:19, 1:21) and policy issues (1:20, 1:22, 1:23, 1:28, 1:29, 1:30). Their perspectives on the ban of maize were both positive (1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:17) and negative (1:9, 1:10, 1:15). On Stakeholders indicated that the ban on poultry products importation increased local production (1:47, 1:51) and food safety (1:56, 1:58), however, others indicated that it led to an increase in the price of day-old chicks and poultry feed (1:52, 1:53, 1:54). Conclusively, the perspectives of stakeholders in the poultry subsector suggest that government policies had positive impacts. Therefore, it is imperative that policy formulation stems from stakeholders’ engagement and implementation is phased, incremental, and gradual.},
