Review of Cassava Production in Nigeria: Trends and Decomposition Analysis Approach
Tarım Ekonomisi Araştırmaları Dergisi, 2020
This study analyzed the growth rate, the instability in the growth trend, and examined the contributions of yield and area to cassava production output in Nigeria. Using time-series of the selected variables which spanned through 1961-2018, the compound annual growth rate (CAGR) was estimated for the harvested area, production, and yield of cassava. The study adopted Coppock's instability index (CPII) to measure instability in cassava production. Between the period, TE1963-2018, cassava yield oscillated between 9.1 tonnes/ha (TE2018) and 11.9 tonnes/ha (TE2010) while the output fluctuated between 7.8 million tonnes (TE1963) and 59.5 million tonnes (TE2018). In this same period, the CAGR for yield (0.1%), area (9.7%) and production (9.9%) were positive and statistically significant at 1% except for yield. The decomposition analysis for the period revealed that the increase in output was largely due to an increase in area harvested during the period (110.4%). In view of these and other findings, the study recommends intensive planting of improved cassava varieties under well mapped out sustainable strategies to optimize production.
Future Trends in Cassava Production: Indicators and its Implications for Food Supply in Nigeria
Asian Journal of Agricultural Extension, Economics & Sociology, 2021
The growing demand for cassava and its products has continued to stretch the supply of cassava globally. Nigeria is a leading producer of cassava in the world yet, there are concerns that if appropriate policy strategies are not adopted to increase production, the current fragile situation of food insecurity in Nigeria may be worsened. Besides the increasing number of gigantic cassava-based industries spring up in Nigeria, the rapidly growing population of consumers is another factor that may further disrupt the relatively stable cassava market in Nigeria in the future. Therefore, "ceteris paribus", the study determined the appropriate quantitative models to forecast the trends in cassava production indictors in Nigeria. Using the historical series (1961-2018), 12-year period (2019-2030) forecasts were made for each of the production indicators as follows: 106 million tonnes (production output), 7.7 tonnes/ha (yield) and 9.6 million hectares (cropped area) in 2030. The study extrapolated the expected food supply from the expected production output in the forecast period using the 2014 FAO estimates of food supply per caput. Thus, in 2030, cassava food supply per caput was found to decline from 267 Kcal/capita/day in 2014 to 239 Kcal/capita/day. The study concludes that despite keeping the future demand of the growing cassava-based industries constant, cassava production is expected to continually increase but future food supply per caput would decline. However, the growing cassava-based industries globally is expected to hugely influence the future cassava market dynamics.
Time series secondary data on area, production, productivity of cassava and other principal crops in Ibadan Metropolis were arranged into 3 groups P 1 (1980-81 to 1994-95), P 2 (1995-) respectively based on farm sizes. 150 households comprise 50 each from small, medium and large farm, spread over the three areas namely: ajibode, eleyele and ijokodo were conducted using pre-tested interview-schedule and pertain to the agricultural year 2010-11. Absolute relative changes, compound growth rate, component analysis, techniques were employed to analyze the collected data. Area, production and productivity of cassava and wheat increased during period P 1 and overall period P 3 but decreased in their second period P 2 . Area of cassava, wheat and sorghum decline during second period but due to increase in productivity, production increases. The production of cassava and yam shows negative growth in production and this was mainly attributed to higher decline in acreage of the crops despite of positive and significant growth in productivity. The component analysis revealed that yield contribution (55 to 86 per cent) was higher in change of cassava, wheat and maize production while area contribution was significantly higher in other selected crops.
Cassava Productivity Growth in Nigeria
Asian Journal of Research in Agriculture and Forestry
Cassava has gained prominence in the world and has become economic crop in the Nigerian agricultural sector. Secondary data was used for this study. The required variables were extracted from General Household Survey Panel Data (GHS-P). The GHS-P is a nationally representative survey of households across Nigeria covering urban and rural sectors. Analytical tools used included Total factor productivity and Markov chain. 82% of populations of Cassava farmers are in the rural areas and close to 73% were young adults including both male and female involved in cassava production. Approximately 65% of the cassava based farmers were single that not yet married and most of the farmers were educated and about 80% and 98% of the cassava based farmers did not have access to credit facilities and extension personnel respectively. Generally, the cassava productivity growth was erratic and very small proportion of cassava farmers that were in lower productivity reduced overtime, while the minimal...
OVERVIEW OF THE TRENDS OF CASSAVA PRODUCTION AND ITS COMPETING CROPS IN OYO STATE NIGERIA
Cost studies are backbone in the field of research in agricultural economics which is quite evident of the fact that all systematic research in our discipline started with cost studies not only in Nigeria but at abroad also. These studies went through various stages and were refined every time with the experience, looking to the nature and limitations of agricultural business. Cassava has a great worldwide significance due to its diversified uses. Being grown over 60 million hectares of land in Nigeria, it is cultivated through in almost all the states in Nigeria, the major cassava growing areas of the country is Ibadan metropolis which were chosen for conducting the study. The selected state account for 22 per cent of the country cassava area but contribute only 6 per cent to national cassava production due to low productivity. Taking into consideration the importance of the cost studies for farm planning and policy decisions at the micro level, the present study was conducted to analyze the variations in cassava production.
Cassava Production in Africa: A Panel Analysis of the Drivers and Trends
Heliyon, 2023
Cassava is Africa's most important tuberous crop. It is an all-year-round cheap and reliable staple food for millions of Africans, making it vital for food security on the continent. However, cassava production in Africa is hindered by a persistent problem of low yield per hectare. This study addresses the dearth of research on the specific influences of area harvested and yield per hectare on cassava production in Africa. This work uses panel data from 37 African countries from 1961 to 2020 and sheds light on three key aspects. Firstly, it investigates the extent and nature of the low yield per hectare problem, offering insights into its underlying causes and implications. Secondly, it examines the interplay between area harvested and yield per hectare, revealing the factors driving the observed trends in cassava yields on the continent. Lastly, this study contributes to the achievement of Sustainable Development Goals, particularly Goal 15: Life on Land and Goal 2: Zero Hunger, by providing valuable information to enhance cassava production sustainability. The findings indicate that approximately 95.6% of the variability in production can be explained by changes in the area harvested, around 1.1% by yield variability, about 27.6% by consumer price index and 1.8% by temperature changes. Notably, the study observes a significant increase in the area harvested by 16.8 million hectares and average yield levels varied between 5.7 and 9.6 tonnes per hectare. The analysis also reveals a disparity in translating gains from disease eradication and introducing high-yield, disease-resistant varieties into smallholder cassava farming. In conclusion, the study highlights the potential for sustainable intensification of cassava production as a viable pathway to enhance absolute and per-hectare yields while promoting farmers’ income and mitigating cassava cultivation-related deforestation. Understanding and addressing the low yield per hectare problem in cassava production are crucial steps toward ensuring food security and achieving sustainable agricultural practices in Africa.
PROJECTION AND RESOURCES ADJUSTMENT IN CASSAVA PRODUCTION IN OYO STATE, NIGERIA
Projection was made by the use of ARIMA model, contribution of area and yield towards cassava production was done by decomposition analysis and adjustment in cropping pattern was estimated by calculating index level. Forecast result showed that maximum value of area is 843.0 thousand hectares which would be expected in 2013-14 while minimum value is 826.0 thousand hectares which is likely to occur by the year 2025-26. Production forecast revealed maximum value of 1407.0 thousand tons which would be expected by 2025-26 and the minimum value of 1181.0 thousand tons in 2012-13.

Conclusively, the current cassava yield levels can be increased by a factor of five by emphasizing nutrient and soil health management and irrigation, particularly in areas characterized by a shorter rainy season (Sudan Savanna) in Nigeria.
GROWTH RATE AND DOUBLING TIME OF YAM AND CASSAVA PRODUCTION IN NIGERIA
The growth rate and doubling time of yam and cassava output, yield and acreage was investigated from data obtained from a secondary source and analyzed using the exponential and quadratic function in trend variable. The study revealed the growth rate during the period under consideration, there were growth as well as retardation, and it also shows acceleration, stagnation and deceleration at different sub-periods for the variables. Average growth rate of 6.7% for yam hectares, 0.03% for yam yield and 7.2% for yam output, translating into doubling time of 10 years for yam hectare, -0.8 year for yam yield and 62 years for yam output were estimated. The average rate of growth for cassava hectare was 11.1%, -0.498% for cassava yield and 8.5% for output. This translates to doubling time of 1 year for cassava hectare,-0.5 year for cassava yield and 14 years for output. This study also revealed that the growth rates of yam and cassava production over the years have more of stagnation than acceleration and deceleration based on the changes in the macroeconomic policy of the country, which implies that planning of the macroeconomic policies were not better than the previous ones. It therefore, indicates that, although there has been some level of increase in some of the sub-periods, the policy presentation for yam and cassava did not in any way translate to sustained increase.
