The study analyzed the effect of guinea worm disease on rice farmers’ productivity in Abakaliki, Ebonyi State, Nigeria. Four research questions were raised and two hypotheses formulated to guide the study. Data for the study were obtained from 120 rice farmers in the area using multistage sampling procedure and analyzed using descriptive statistics and multivariate binary logistic regression model. Result showed that 67.5 percent of respondents were male; 43.3 percent were ages between 51-61 years; 69.2 percent were married; 32.5 percent had tertiary education; 50.8 percent had between 11-15 years of farming experience and 37.9 percent have 16-20 persons’ family size. Also, 49.2 percent of respondents sourced their drinking water from the stream and 36.7 percent have farm size less than 3 hectares. The result revealed that 42.5 percent of the respondents were infected with guinea worm disease, out of which 100 percent had family size between 1-5 persons; 56.9 percent spent between N10,000- 50,000 for the treatment; 62.7 percent lost less than 1 month to GWD; 66.7 percent employed labour due to GWD; and 74.5 percent spent between N100,000- 200,000 in the farming season. The result of multivariate logistic regression showed that the prevalent of GWD reduces as the ages and level of education of the farmers’ increases while increase as the years of farming experience increases. The result also revealed that source of drinking water and family size of rice were not significant with the prevalent of Guinea Worm Disease in the area. On the average, result indicated that family size, farm size of the infected group and guinea worm disease generally has significant effect on rice farmers productivity in the study area with coefficient regression of 1.891 and odd ratio of .151.
1.1 Background of the Study.
The state of health of a farmer and their agricultural productivity can be said to have a complex interrelationship. Increased productivity results to food sufficiency which the ever growing world population depends for sustainability. To adequately sustain the population in avoidance of food insecurity, agricultural productivity must be maintained optimally through efficient use of factors of production. Basically, of the four factors of production, labour remains the most essential factors that manipulate farm inputs to produce efficient outputs. In Nigeria, the indispensability of labour emanates from the fact that its agricultural system is labour intensive oriented.Essentially, the economics of rice production from the last two decades significantly impacted the national development of the Nigeria State. This impactful popularity of rice was derived from the rising level of productivity, level of income and the relative convenience with which it was produced, processed and persevered (Onwuchekwo, 1988 cited in Ekpe&Alimba, 2013). As one of the major stable food crops in Nigeria favoured by the ecological nature of the environment, rice provide basic nutritional materials, remain a major employees of labour and source of income (WARDA, 2004). Also, as the world leading food crop, rice provides industrial raw material for the manufacturing of macrony, spaghetti, flour as well as in commercial production of beer and some other beverages in brewing industries. Nevertheless, the efficiency of rice production depends on labour effectiveness. However, considering the prime importance of labour in relation to agricultural productivity, health plays a vital role in either accelerating the level of agricultural produce or retarding the production.
Health according to World Health Organization is defined as a state of complete physical, mental and social well-being of a person. The importance of health as a form of human capital cannot be over emphasized. Ajani and Ugwu (2008) states that good health and productive agriculture are important in the economy of any nation especially in the fight against poverty. Health enhances work effectiveness and the productivity of an individual through increase in physical and mental capacities. In other word, health affects agricultural systems by affecting the health of the producers. It is worthy of note that healthier workers are physically and mentally more energetic and robust. They are more productive and less likely to be absent from farm work whereas poor health may result in loss of work days or decrease worker capacity, decrease innovative ability and ability to explore diverse farming practices (Awoyemi and Soruunmi, 2009). In furtherance to the implication of poor health, Greenway (2004) pointed out that poor health increases present and future food insecurity through its impact on the household’s ability to produce food because of labour shortages and loss of knowledge about farming method; the household’s ability to buy food because of impoverishment due to loss of productive family members; the community’s ability to produce and buy food as the epidemic reaches every home and neighbors and become too burdened to help each other with food, loans or hands in the field; and the country’s ability to import food as ill-health reduces Gross Domestic Product Per Capita by an estimated 1% annually in Africa ( Greenway, 2004).Likewise, as put by Asenso-Okyere (2010), poor health resulting from disease affect physical strength and work days/hours available for farm work. Since agricultural productivity is dependent on physical strength and stamina, and therefore good health, it is more probable that health shocks directly affect worker productivity. Equally, labour-diseases involving high medical expenditures tend to deprive farming households of resources to invest in experimentations on improved practice and adoption of new technology. Poor health may reduce farmers’ ability to innovate, experiment, and operationalize changes in agricultural systems. Worst still, serious health issue of farmers resulting in catastrophic expenditures may also result in depletion of productive assets such as sale of draught animals and sale of cultivable land; and the consequence of these actions may include reduction of farm size as a result of reduction in labour strength; cultivation of less intensive crops, and reduction in farm inputs resulting in poor livelihood.
However, in Nigeria, a number of preventable diseases have affected health capital and guinea worm disease remains one of the greatest impediments to productivity in rural areas. Recent studies have indicated that guinea worm disease contributed significantly to the lossof working days, output, inefficiency and general decline in productivity (Ugwu, 2006). This may be responsible for the present distant between the demand-supply structures of rice production. Thus, this indication is most detrimental prior to the fact that agriculture is the main occupation and source of livelihood to over 85% population of Nigerians and 95% of the rural dwellers (WHO, 2006).
In Abakaliki in Ebonyi State for instance, agriculture continued to be one of the most important drivers of poverty reduction, the highest employer of labour and the bedrock of economic growth of the people. Majored in the production of yam, rice and other crops including other farming activities, the farmers in Abakaliki are small farm holders (Onugu, 2008). Meanwhile, Ebonyi state in general is one of the highest-producer of agricultural produces in Nigeria with rice retaining prominence and has been reportedly rated as the third in the series of the most infested states by Guinea Worm Education Programme (2004). Thus, based on the reported prevalence of Guinea Worm diseases and the place of Abakaliki in particular and Ebonyi State in general in rice production in Nigeria, the researcher is motivated to carry out a study to ascertain the effects of guinea worm diseases on rural productivity as it influences the livelihood of rice farmers in Abakaliki, Ebonyi State.
