Item Open Access Agricultural Production and Climate Change: Need for Proper Extension Policy Formulation in Nigeria(U. P., 2012-08) Anaeto, F. C.; Asiabaka, C. C.; Onweagba, A. E.; Ohajianya, D. O.; Nnadi, F. N.; Ifeanyi-Obi, C. C.; Ajaero, J. O.; Ukpongson, M. U.; Ugwoke, F. O.Changes in climate are expected to have significant impacts on farm yields and product quality as a result of changes in temperature, moisture, air and soil. This paper reviews the effects of climate change on agricultural production and the need for extension policy formulation. The paper further dwelt on the need for sound agricultural policy but observed that much cannot be achieved in that direction without efficient and effective extension system. It recommends a well articulated and comprehensive agricultural extension policy which will address properly the issue of climate change and its mitigations/adaptation.Item Open Access Agricultural production and climate change: Need for proper extension policy formulation in Nigeria(U.

P., 2017-03-31) Anaeto, F. C.; Ohajianya, D. O.; Mathew-Njoku, E. C.; Ani, A. O.; Korie, O. C.; Osuagwa, C. O.; Uzor, U. C.; Adolph-Nnebene, E.This study analyzed factors affecting smallholder farmers’ decisions to use fertilizer in Ohaji/Egbema area of Imo State, Nigeria. Primary data were obtained between April and June 2015 with structured questionnaire from 202 randomly selected smallholder farmers. Data obtained were analyzed using descriptive statistics and probit model. Factors affecting smallholder farmers’ decisions to use fertilizers were farm size, education level, extension contact, net farm income, farming experience, cost of fertilizer, and perceived soil fertility status. Mc-Fadden’s Pseudo-R2 value of 0.6879 indicates that the independent variables included in the probit model explain 69% significant proportion of the variations in smallholder farmers’ decisions to use fertilizer. The pobit model predicted 82% of the factors affecting fertilizer use by smallholder farmers. The role of extension service in improved technology use cannot be over emphasized. The distribution of fertilizers to farmers through the GSM services should be restored since it proved an effective mechanism to reach smallholder farmers in input supply and distributionItem Open Access Climate variability, incidences and mitigation strategies among poultry farmers in Abia state, Nigeria(Conscientia Beam., 2018-09-28) Odok, G. N.; Unaeze, H. C.; Ogueri, E. I.; Essien, U. A.; Ukpong, C. A.; Bassey, J. E.; Onini, M. T.; Ezebuike, I. R.; Ohajianya, D. O.This paper investigated climate variability, incidences and mitigation strategies among poultry farmers in Abia State, Nigeria. It specifically analysed the trend of climate variables over the period of 30 years, the perception of poultry farmers as regards the impact of climate variability on poultry production in the study area, and examined the different mitigation strategies adopted by these farmers. A multi-stage sampling technique was employed in choosing the required sample of 120 poultry farmers. Data were collected with validated structured questionnaire, and analyzed using descriptive statistics. The result showed a high inter-annual variability in the volume of rainfall from 1983 to 2012 with insignificant correlation (0.0781) between rainfall volume and time. Also, the result showed reduction in number of rainy days and sunshine duration between 1983 and 2012 with correlation coefficients of 0.146 and 0.132respectively. Temperature had significant positive relationship with time with correlation coefficient 0.638.High mortality rate, disease outbreak, smallness of egg size, poor quality of egg shell, heat stress and reduced feed intake actually impacted on poultry production in the study area. Climate variability was therefore found to have affected poultry production in the study area and this has serious environmental and food policies implication. The respondents identified the use of climate resilient breeds, closeness to hatchery, feed improvement, mixed farming, use of artificial cooling system and stocking less during harsh season as major mitigation strategies to climate variability. It is therefore recommended that the government should come up with appropriate policy that will assist the poultry farmer to be more resilient and able to cope with effect of climate variability. Policies should also be formulated to reduce the emission and accumulation of green-house gases in our environment.
