Retrospective evaluation of scaling associated with the IITA Cassava Weed Management Project (CWMP): Final project

The Cassava Weed Management Project (CWMP), funded by the Bill and Melinda Gates Foundation (BMGF) from 2013-2018, aimed to promote the use of safe and environmentally friendly herbicides for effective weed control in cassava production in Nigeria. This retrospective evaluation, conducted by a consortium of experts from the International Food Policy Research Institute (IFPRI) and Sahel Consulting Agriculture and Nutrition Limited, examined the extent to which the private sector has scaled up the herbicides tested and recommended by the CWMP, as well as the factors influencing companies’ decisions to register and deploy these products. The evaluation, conducted in 2023-2024, employed a mixed-methods approach that relied heavily on the qualitative approaches to uncover underlying factors affecting scaling and adoption. The methods included document reviews, key informant interviews (KII), focus group discussions (FGD) with cassava farmers, mystery shopper surveys of agro-dealer shops, and quantitative analysis of secondary data from sources like official company data and the Living Standard Measurement Study – Integrated Survey on Agriculture (LSMS-ISA). The evaluation findings indicate that the private sector has made notable efforts in scaling up some of the recommended herbicides, but the extent of scaling varies across different products. Relying on sales data from herbicide companies to estimate the number of cassava farmers who have adopted various herbicide products over the last five years, the evaluators found that Glyphosates stand out in terms of number of cassava farmers who have adopted these herbicides over this period. Owing to missing sales data from the herbicide companies, our reported estimates focus only on the number of farmers that purchased the herbicides in the most recent year of sale. We estimate that more than 200,000 cassava farmers used the herbicides Touchdown and Force-Up in 2023, and more than 120,000 cassava farmers used Sarosate in 2023. We found that only about 2,800 farmers used Primextra Gold in 2021. Gallant Super was also estimated to have been adopted by over 23,000 in 2023, Vigor adopted by over 5,000 farmers in 2023, and SlashaGold by about 4,500 cassava farmers. While these estimates are based on the best available data from the companies, it is important to exercise caution in citing these figures due to the lack of precise records of sales of specific herbicides to cassava farmers.

Bundling cash loans with agricultural input loans for farmers in Nigeria: A pilot study

Bundling cash loans with agricultural input loans for farmers in Nigeria: A pilot study

Credit allows borrowers to access funds required to make an investment before returns materialize. For smallholder farmers, who must invest in agricultural inputs (i.e., seeds, chemicals, equipment, land, and labor) during the planting season before earning income from the sale of agricultural produce after har vest, credit helps alleviate liquidity constraints and promotes the ability of local agricultural production to support nutrition and food security. In rural Nigeria, access to credit—especially formal credit from finan cial institutions—is limited. Data collected in 2020 show that less than a third of households in rural Ni geria report using credit in the previous 12 months and only two percent of rural households borrowed credit from a financial institution. The rest is borrowed informally from friends, family, or local money lenders. In the absence of credit, smallholder farmers must cover the costs of agricultural production with their own funds that they have available during the planting season. This constrains agricultural production and contributes, in part, to the large gaps in agricultural productivity between high-income and low-in come countries around the world.

Conflict-induced shocks and household food security in Nigeria

Conflict-induced shocks and household food security in Nigeria

Conflicts such as the Boko Haram insurgency, herder–farmer conflicts, and armed banditry attacks are major concerns affecting the livelihoods and food security of households in Nigeria. In this paper, firstly, we reviewed and synthesized the nature, spatial extent, and implications of conflicts on food security in Nigeria. Secondly, using survey data and econometric models, we examined the effects of conflict-induced shocks, such as forced migration and fatality on household food security indicators. Our review shows that the underlying causes for the majority of violent conflicts in Nigeria are linked to competition for productive resources, economic inequality, and ethnoreligious tensions. Review results also indicate spatial variations in the nature and severity of violent conflicts in Nigeria. While the Boko Haram insurgency is prominent in the North-East, the North-Central is mainly exposed to herder–farmer conflicts, and there is a high prevalence of communal conflicts in the South-South region of the country. In terms of gender dimensions, women are more vulnerable to conflicts and shoulder more social and economic burdens than men. From our empirical analysis, we found that conflict-induced shocks such as forced migration, fatality, abduction, and injury significantly exacerbate the severity of food insecurity and deteriorate the dietary diversity of households. Conflicts also affect agricultural investment decisions with a negative consequence on future agricultural productivity and food security. Based on the findings, the key policy suggestions include the need for tailored interventions to resolve state or region-specific conflicts, policy interventions on property/land rights and livestock management systems to address herder–farmer conflicts, and targeted investments in building the resilience capacity of households.
