Item ANALYSIS OF THE IMPACTS OF CLIMATE CHANGE AND VARIABILITY ON WATER ACCESSIBILITY AND SUPPLY IN YAURI, KEBBI STATE, NIGERIA(Samanala Educational Centre, Belihuloya, Sri Lanka and Department Economics, Gombe State University, 2016) Rhoda Mojisola, Olanrewaju; Akpan, G.P.The study examines the impacts of climate change and variability on water accessibility and supply in Yauri, Kebbi State. Both primary and secondary data were employed for the study. A total of 266 questionnaires were administered to the residents in the study area. Secondary data used include meteorological data (rainfall, minimum and maximum temperature and evaporation) from NIMET, Yauri for the period of31 years that spanned between 1 984 to 2014. Also data on quantity of water supplied from Yauri Waterworks were collected. The statistical technique! used include descriptive statistics, Pearson Product Moment Correlation, Multiple Regression Analysis and TrendAnalysis. The result from the descriptive statistics revealed that 49.8 of the respondents lack access to water. In the same vein, 38.4, 31.0 and 18.4 indicated that effects of dry season, climate change/variabilify and high temperature account for low water accessibility in the Study area respectively. Result from Pearson moment correlation revealed a strong positive relationship (0.76) between monthly rainfall and monthly water - supply at 0.05 significant levels. The result of multiple regression analysis with four explanatory variables has an R2 of 0.526 which confirmed that 52.6 of variation in water supply can be explained by climatic factors. Recommendations were made which include; curbing of climate change induced anthropogenic activities, effective water resources management and planning among others.Item FARMERS' PERCEPTION AND ADAPTATION TO CLIMATE CHANGE IN YAURI COMMUNITY OF KEBBI STATE, NIGERIA(Faculty of General Studies, Federal University, Dutse, 2016) Rhoda Mojisola, Olanrewaju; Akpan, G.P.Agriculture is the main source of support for the majority of the rural and urban households in developing countries of Africa including Nigeria. Hence, adaptation of the agricultural sector to the negative effects of climate change may be necessary to ensure food security for the country and to protect the livelihood of rural households (Abid et ul, 20 IS). The earth planet has warmed and cold many times during the 4.65 billion years of its history. At present, Earth appears to be "Icing rapid warming which most scientists believed result, at least in purt, from human activities .Item IMPACTS OF CLIMATE VARIABILITY ON HYDROELECTRIC POWER GENERATION IN SHIRORO STATION, NIGERIA(Iranian Journal of Energy and Environment, 2018) Rhoda Mojisola, Olanrewaju; Olatunji, O.W.; Akpan, G.P.Hydro Electric Power (H.E.P.) is a critical infrastructure that powers industrial growth and economic development of any developing nation. However, variability in climatic condition is already having serious impacts on H.E.P. in Nigeria. The study examined the effect of climate variability on hydroelectric power generation in Shiroro Station Nigeria. Data used for this study were acquired mainly from secondary source. The climatic, Hydrological and power generation data used are already prepared document from 1990 to 20 14 (25 years) period. The data were sourced directly from the production and Hydrological department of North South Power (N.5.P.). Relevant literature, journals and internet materials were also used for the study. Data collected were subsequently analyzed using inferential statistics such as trend analysis, reduction pattern analysis, spearman rank correlation and multiple regression analysis. Result revealed that there is variability in climatic elements and hydrological variables from year to year. Multiple linear regression analysis revealed that climatic/hydrological variables can only explained 75.4 variability in the amount of hydro power generated in Shiroro Station. The study calls for the development of pumped water systems so that the tail water can he reused particularly during periods of little or no rainfall and low inflow.Item RAINFALL VARIABILITY AND MAIZE YIELD PRODUCTION PATTERN IN SOUTHWESTERN NIGERIA(Faculty of Social Sciences, Usmanu Danfodiyo University, 2017) Rhoda Mojisola, Olanrewaju; Aderibigbe, S.O.; Akpan, G.P.Rainfall is one of the key climatic elements that determine the success of agriculture and water resource characteristics in many parts of Nigeria. However, climate and rainfall variability has impacted negatively on maize production in different regions of the country. The paper examined the impacts of Inter annual rainfall variability on the yield of maize in Southwest Nigeria for a period of 24 years (1990-2013). The three states of Ondo, Oyo and Ogun were selected for the study. The selection is due to availability of data. Climatic data of rainfall was sourced from the archives of the Nigerian Meteorological Agency (NIMET), while maize yield data were obtained from the Agricultural Development Programs (ADP) of each state. The data were subjected to descriptive statistics like percentage among others. Inferential statistics used include Pearson moment correlation, simple regression analysis and GIS interpolation analysis. The Coefficient of variation (CV) of rainfall amount in all the three states reveoled that rainfall amount within the three locations is highly heterogeneous, while the Standard Anomaly Index revealed that Ondo State received the highest total amount of rainfall, followed by Oyo and Ogun State respectively. This trend was also reflected in the pattern of annual maize yield which was highest in Ondo (2.19 tons/ha), as compared to Oyo and Ogun that observed yields of 1.57 ton/ha and 1.40 tons/ha respectively. The result of Simple regression analysis showed that inter annual rainfall variability accounts for 63:40, 38.90 and 57.00 variation in maize yield across On do, Ogun and Oyo States respectively. The study recommends that Maize production should be monitored to identify the most critical phase of maize growth to various climatic factors particularly rainfall among others.
