Optimal transportation and spatial integration of regional palm oil markets in Nigeria
(Intemational joumal of operations research and information systems, 2016) Nwauwa, L. O. E.; Adenegan, K. O.; Rahji, M. A. Y.; Awoyemi, T.T.
"The poor quality of transportation infrastructure in Nigeria impacts negatively on the competitiveness of palm oil. This leads to increased inter-regional transportation cost, delayed time of arrival to the destination and lowered transaction efficiencies in the distribution chains. Primary and secondary data were used. Random sampling technique was used to collect data from 276 distributors in main palm oil markets. Data were analyzed using linear programming and Ravallion model at 0.05 a-level. Results of the data analyzes show that average cost of transporting palm oil from the production market to the consumption market was N5,831.9 per MT. Observed transportation cost was N60,724,830.5 while the optimal cost was N44,003,500.30 indicating a 38.0% reduction in total cost of transportation. Highest optimal allocations to the destination markets were Owerri-Jos (133,500 MT), Ondo-Lagos (107,200 MT) and Port Harcourt-Kano (82,000 MT) at minimum transportation cost of N5,750, N4000.7and N6500.0 per MT respectively. Two lag periods were identified signifying that it takes about 1-2 months for price information to spread across the markets by the model. Six of the 27 market pairs exhibited high short-run market integration for both lag periods with Port Harcourt-Abuja market pail: indicating the highest (0.1 and 0.004). The lowest short-run market integration was recorded in Ondo-Minna market pair indicated by 1.4 and 17.4 respectively. Policies that will enhance redistribution of palm oil supply between producing and consuming regions should be pursued. "
Primal-dual links to spatial equilibrium market model for palm oil in Nigeria
(International journal of operations research and information systems, 2016) Nwauwa, L. O. E.; Adenegan, K. O.; Rahji, M. A. Y.; Olaniyi, O. Z.
"Distribution of agricultural produce is undertaken to bridge the gap between production and consumption arising due to spatial separation between areas of surplus and deficit. An investigation of primal-dual links to spatial equilibrium model and integration of palm oil markets in Nigeria was carried out using transportation model. Two-stage sampling technique was used to collect data from 3 markets and 276 distributors. Data were analyzed using linear programing model. Average cost of transportation per mode was bus (N17, 173), truck (N 10,357) and lorry (N5,831 ) respectively. Total transportation cost of N347,809,600.6k was observed compared to a minimized objective cost of NI42,536,800.30k produced by the program. Highest optimal allocation to the destination markets using the different mode of transportation were Port Harcourt-Lagos by lorry (103,200 MT), Owerri- Maiduguri by truck (21,200 MT) and Ondo-Lagos by bus (19,800 MT) respectively. Subsidized cost of public transport facilities will reduce high cost of transportation. "
