Abstract

Improving the agricultural productivity and welfare of rural farming households is important for many governments, especially in low- and middle-income countries like Nigeria, where agriculture plays an important role in the economy. Increasing access to agricultural extension is often suggested as a way to raise farmer productivity and incomes. However, empirical estimations of the causal impact of agricultural extension services in Nigeria are few, especially those that address internal and external validity concerns. Improved estimation of the effectiveness of agricultural extension can support evidence-informed decision-making by agricultural policymakers. In this study we used three waves of the Nigerian General Household Survey to advance understanding of the factors associated with farmers’ use of agricultural extension services, and to examine how receiving extension support might improve welfare among rural farm households in Nigeria. Through random effects regression with endogenous treatment effects, we found that asset ownership, use of inorganic fertiliser, and access to credit were positively associated with the use of extension services. We also found positive associations between use of extension services and household food security and assets. Receiving agricultural extension service was associated with a 16% reduction in food insecurity and a 64% increase in household assets. Further disaggregating extension services by the type of advice obtained showed positive associations with welfare outcomes for households that received advice on new seeds and fertiliser, but mixed results for those who received advice on animal care and marketing. Receiving advice on new seed varieties and fertilisers was associated with a 12–15% reduction in food insecurity and a 92–113% increase in household assets. Our findings add to the body of evidence that suggests enhancing farmers’ access to extension can improve the welfare of farmers. Government policy needs to consider factors that limit or promote farmers’ access to agricultural extension services, so that Nigerian farmers can equitably benefit from the potential welfare gains associated with agricultural extension.

尼日利亚与获得农业推广服务相关的福利收益
摘要 提高农业生产率和农村农户的福利对许多国家的政府来说都很重要,尤其是像尼日利亚这样的中低收入国家,因为农业在这些国家的经济中发挥着重要作用。增加农业技术推广的机会常常被认为是提高农民生产率和收入的一种途径。然而,对尼日利亚农业推广服务的因果影响进行的实证估算很少,尤其是那些解决内部和外部有效性问题的估算。改进对农业技术推广效果的估计,可以为农业政策制定者做出有依据的决策提供支持。在本研究中,我们利用尼日利亚三次家庭调查,进一步了解农民使用农业推广服务的相关因素,并研究接受推广支持如何改善尼日利亚农村农户的福利。通过内生处理效应的随机效应回归,我们发现资产所有权、无机肥料的使用和信贷的获得与推广服务的使用呈正相关。我们还发现,推广服务的使用与家庭粮食安全和资产之间存在正相关。接受农业推广服务可使粮食不安全程度降低 16%,家庭资产增加 64%。根据获得建议的类型对推广服务进行进一步分类,结果显示,获得新种子和化肥建议的家庭与福利结果呈正相关,而获得动物护理和营销建议的家庭与福利结果呈负相关。接受新品种种子和化肥建议的家庭,粮食不安全程度降低了 12-15%,家庭资产增加了 92-113%。我们的研究结果补充了大量证据,这些证据表明,提高农民获得推广服务的机会可以改善农民的福利。政府政策需要考虑限制或促进农民获得农业推广服务的因素,以便尼日利亚农民能够公平地受益于与农业推广相关的潜在福利收益。

期刊介绍: Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches. Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet. From this perspective, the journal covers the following areas: Global food needs: the mismatch between population and the ability to provide adequate nutrition Global food potential and global food production Natural constraints to satisfying global food needs: § Climate, climate variability, and climate change § Desertification and flooding § Natural disasters § Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production § Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production The sociological contexts of food production, access, quality, and consumption. Nutrition, food quality and food safety. Socio-political factors that impinge on the ability to satisfy global food needs: § Land, agricultural and food policy § International relations and trade § Access to food § Financial policy § Wars and ethnic unrest Research policies and priorities to ensure food security in its various dimensions.
