Peri-urban Development and Food Crop Loss in Ibadan, Nigeria (1986-2019)

Abstract

This paper quantifies the loss in agricultural land with regard to cassava and maize production in peri-urban Ibadan from 1986 to 2019. Landsat images of four local government areas — Akinyele, Ido, Egbeda, and Oluyole — from 1986 to 2019 were used, while crop loss per hectare was calculated based on the average tons produced in Nigeria. The agricultural land loss occasioned by peri-urban development was 36,238.15ha, 59,930.23ha, 13,353.035ha, and 33,638.23ha in Akinyele, Ido, Egbeda, and Oluyole LGAs respectively. Consequently, between 1986 and 2019, 3,418.69 tons of cassava and 22,648.84 tons of maize were lost in Akinyele, 5,653.80 tons of cassava and 37,456.39 tons of maize in Ido, 1,259.72 tons of cassava and 8,345.65 tons of maize in Egbeda, and 3,173.42 tons of cassava and 21,023.89 tons of maize in Oluyole LGAs. To curb further decrease in crop production, investment in spatial vertical development is imperative.
