Farmers' perceived effects of climate change in cocoa production in Kwara State

Abstract

The effects of climate change in Nigeria are already being felt as the frequency and intensity of extreme eventslike droughts and floods have increased. In mature cocoa plants, water deficit and excess result in low yield andincrease the level of capsid and black-pod damage. Cocoa seedling mortality is encouraged by prolonged dryseason due to changes in climate. The study investigated the perceived effects of climate change on cocoaseedling growth, flowering, pod development, yield, leaves, tree, insect pest and disease occurrence. It examinedperceived climatic factors and amount realized from cocoa beans in Kwara State. A multi-stage randomsampling procedure was used to select 60 cocoa farmers from three out of eight Local Government Areasproducing cocoa in the study area. Interview schedule instrument was used in data collection and analyzed withdescriptive statistics and correlation analysis. The results revealed that most (60%) of the farmers believedclimate change retards cocoa seedling growth and lead to death. Half (50%) of them opined that climate changedelays flowering of cocoa. Majority (70%) perceived it to delay pod development resulting in low yield. In termsof insect pest and diseases occurrence, 51.7 percent indicated that climate change altered crop yield and lossesin cocoa farms. Many farmers (58.3%) feel it makes cocoa leaves to be abundant while more of them 65%claimed that climate change retards tree development for optimum production. However, 61.7% had highperception about the effect of climate change on cocoa production. Low Rainfall accounting for 61.7% wasobserved to be the main climatic factor contributing to climate change in the study area. The revenue realizedfrom sales of cocoa beans was statistically related to farmers’ perceived effect of climate change on cocoaproduction (r = -0.412, p = 0.001 at p<0.05). The farmers’ perception of climate change is a reflection of theglobal problems posed by variations in weather impacting food production and income. There is need forconcerted efforts that will mitigate the effects of climate change on cocoa production.
