The Determinants of Urban Households' Demand for Cassava and Cassava Products in Kaduna, Northern Nigeria: An Application of the AIDS Model

Abstract

Le manioc est une des tubercules les importantes parmi celles cultivées pour l'alimentation en Afrique de l'ouest et du centre. L'article s'intéresse aux déterminants de la demande de manioc et aux perspectives pour cette culture dans le nord du Nigeria en estimant l'élasticité de la demande de manioc et d'autres racines et tubercules. Le modèle « Système de demande pratiquement idéal » (AIDS) a été utilisé pour estimer les paramètres. Les résultats montrent que la demande de manioc est inélastique par rapport aux prix. L'élasticité par rapport aux dépenses est positive bien que faible. Ceci témoigne de l'évolution du manioc, de bien inférieur à celui de première nécessité. Grâce à ses qualités de conservation, le gari, la forme transformée du manioc, est devenue très populaire. Ce produit qui constitue une excellente source d'énergie alimentaire ne devrait donc pas être seulement considéré comme une culture de subsistance ou la nourriture du pauvre.European Journal of Development Research (2009) 21, 435–447. doi:10.1057/ejdr.2009.15; published online 23 April 2009

Poverty Reduction Effects of Agricultural Technology Adoption: The Case of Improved Cassava Varieties in Nigeria

“…We follow the approach of Zeng et al (2015) and use our yield and cost treatment effects along with supply and demand elasticities from the literature to estimate the poverty reduction effect of adoption. We used a demand elasticity of 0.46 (Tsegai and Kormawa, 2002) and a supply elasticity of 0.7 (Obayelu and Ebute, 2016). The average 2009-2014 market price (P obs ) per kilogram of cassava was US$ 0.14.…”

Relative Profitability of Cassava‐based Mixed Cropping Systems among Various Production Scale Operators in Ogun and Oyo States Southwest Nigeria

“…Cassava is the most important root crop in Nigeria in terms of food security, employment creation and income generation for farm families (Ugwu and Ukpabi, ). Cassava ( Manihot esculenta ) occupies a prominent place in the national non‐oil export commodity (Nweke et al ., ) and is a chief source of dietary food energy for the majority of the people living in the lowland tropics and the sub‐humid tropics of West and Central Africa (Tsegai and Kormawa, ). Cassava is a crop that is well adapted to a wide range of ecological conditions, being tolerant to low soil fertility, drought and pest (Tewe, ) and has been reported as the fourth most important staple of the tropics, providing food and income for more than 750 million people annually (FAO, ).…”

Analysis of Household Demand for Underutilized Indigenous Vegetables

“…Few studies have been directed to demand analysis of UIVs. Previous studies on food demand have made use of double logarithm functions, almost ideal demand and its variants (Akinleye, 2009;Oyekale, 2000;Tsegai and Kormawa, 2002), and quadratic almost ideal demand (QUAID) systems (Obayelu et al 2009). Few of these studies investigated demographic factors influencing demand.…”
