ABSTRACT: In this study, manufacturing accident cost model is proposed. The cost of each class of accidents (Ci) was developed in terms of probability of accident occurrence (ρai), degree of fatality (fi), establishment average annual salary (γ), establishment maximum allowable service year (z), human severity for the class i (Hi), equipment damages (Eqi), service life of the equipment (L), usage life of equipment (T), interest rate (t), acquisition cost of machine (N), machine hour rate (MHR), machine down time (θi), economic implication cost (Eci), value of goods (Qi), total hour lost (βi) and establishment’s overall hourly cost of production (α). Data were collected from eleven textile industries in Nigeria on accidents occurrence and cost of consequences of accidents. Three classes of accidents were identified as: fatal, serious and minor. The collected were used to estimate the model parameters. The unit cost of each class of accidents was estimated to be fatal: N2,665,360.00, serious: N232,750.00 and minor: N56,000.00.

Abstract: The HIV/AIDS epidemic is challenging all aspects of the development agenda. The disease has decimated sub-Saharan Africa’s agricultural labour force and will continue to do so for generations, depleting the region of its food producers and farmers. Not only is the epidemic causing severe reversals in development gains, but it is making development interventions impractical. Communities livelihoods are being permanently eroded and assets depleted with the reoccurring periods of sickness and deaths that the epidemic brings. Inspite of its incapacitating effects on agricultural production and rural livelihoods, and of the fact that up to 80% of the people-in the most affected countries depend on agriculture for their subsistence, the agricultural sector has not been as forthcoming and as innovative in its response, as the situation requires. Labour, a much valued human asset and the foundation of development interventions, is becoming scare and this lack of labour strains traditional coping mechanisms and increase vulnerability. This paper thus investigation the areas HIV/AIDS has affected food production, and rural livelihood such as depletion of labour, loss of generational knowledge and skills, loss of income, land inheritance rights of women and youth and decreasing nutritional status of households. It also reveals extension role in HIV/AIDS mitigation.
