Title

Rural Transportation and Food Crop Production in Akoko South West Local Government Area of Ondo State, Nigeria

Abstract

Inadequate and inefficient rural road transport system are some of the major constraints to food crops production and quality of life of the people in the rural areas of  Ondo Stale, Nigeria, which had been noted for high production of  food and cash crops in the country. This paper examined the adequacy and efficiency of rural transport and also determined its effects on food crop production in Akoko South West Local Government Area of Ondo State. In doing so, 250 copies of designed questionnaire were randomly administered among farmers in the 25 randomly selected settlements in the study area for this study. Data collected were analyzed using frequency tables, percentage and Chi- Squire statistical analysis. It was discovered that some roads in the study area have been seriously eroded and totally cut off, thereby reducing linkage and easy accessibility to farm sites. This not only, has negative effects on food crop production but has badly affected the economic status of the rural farmers. The paper recommends that government should attach much importance to the improvement of rural road network because of its overall positive effect on the rural famers, means of food passage and raw materials to the people and industries in urban centres respectively.

Title

Performance Evaluation of Reactor Types for the Mesophilic Anaerobic Digestion of Poultry Droppings

Abstract

Optimum utilization of poultry droppings anaerobically for energy production and fertilizers for soil conditioning depend substantially on the right choice of the reactor, which is the heart of any chemical process plant. The performance evaluation of reactor types for the determination of the best contacting scheme for mesophilic anaerobic digestion of poultry droppings was carried out. The findings of our study were that anaerobic mesophilic digestion of poultry droppings is a first order reaction with a reaction rate constant of 0.037 day-1; a plug flow digester is preferred to continuous stirred digester for large production and small scale, batch digester is desirable. Digesters in series with inter-stage feed injection or heating would not be necessary. A recycle reactor whose recycled stream serves as inoculum tremendously improves the digester performance and it’s the best option for the mesophilic anaerobic digestion of poultry droppings.

Title

Municipal Solid Waste and Pollution Management in Jalingo Metropolis: Problems, Challenges and Strategies

Abstract

This research present finding of a study carried out in Jalingo Metropolis of Taraba State, Nigeria, with the current solid wastes management practices, problems, challenges and strategies. Prior to the assessment, field work studies indicated that current solid wastes generation rate in the metropolis is 0.34 kg/ca/day and total wastes generation is within the range of 54 tons/day. A detail investigation was made regarding the method of practices associated with source, quantity generated, collection, transportation, storage, treatment and disposal of Municipal Solid Waste (MSW). The data concerning Soldi Waste Management (SWM) in the metropolis was obtained through questionnaire, individual field visit and interviewing responsible persons/municipality. Photographic evidences were also made about generation, storage, collection, transporta-tion, treatment and disposal of MSW. As a result of this study, sanitary landfills were suggested to replace the practice of open dumping and to reduce the reliance on wastes incineration, but yet have some obvious problems and challenges. The paper recommends that, the current method of wastes collection and disposal by the government should be immediately reversed to the new option been campaigned for in the recent time. This is wastes-to-wealth or trash-to-treasure through recycling and community participation to be the right measure in attaining sustainability and effective solid wastes manage-ment in study area.
