Item Open Access Assessment of Climate Variability Trends in Nasarawa State, Nigeria(Department of Environmental Management, Nasarawa State University Keffi, 2020-07-06) Olufemi, Oladeinde Stephen; Joshua, Magaji I.; Ekpo, Salamatu AbrahamChanging global climate has emerged as one of the greatest environmental problems of mankind in the 21st Century. However, there is still a dearth of information regarding the trends and patterns of climate variables at local and specific levels. It is against this background that this paper assessed climate variability trends in Nasarawa State, Nigeria over 21 years' period (1997-2017).Item Open Access ASSESSMENT OF FLOODRISK AND VULNERABILITY OF COMMUNITIES ALONG LOWER NIGER RIVER BASIN, ANAMBRA STATE, NIGERIA(Environmental Science Department, Nasarawa State University, Keffi., 2018-02-10) Ekpo, Salamatu Abraham; Emmanuel, Ozim Chukwunonso; Olufemi, Oladeinde StephenNigeria as a nation suffers the effect of Climate Change majorly through flood events. Anambra State is often one the most affected states due to its location along one of the country's major rivets and its major tributary (River Niger and River Anambra). In an effort to support the government's long term plan to mitigate the associated damages and casualties of flood disaster, this study assessed the floodrisk and vulnerability of communities along the Lower Niger River Basin in Anambra State, Nigeria. Digital Elevation Dataset from ASTER 1-arc second resolution, base map of Anambra State, past flood records and GPS coordinates of communities were integrated to map the flood vulnerability of one-hundred (100) communities to river Niger and river Anambra using ArcGIS 10.1. 18% of the communities were found to be highly vulnerable, 23% were vulnerable while 59% were marginally vulnerable. Communities in Ogbaru and Anambra West LGAs were found to be the mostly exposed to flood risk while those in Idemili south and Ihiala were the least. Urgent Evacuation of People during floods and permanent relocation of all the villages to higher terrain areas was recommended for the highly vulnerable zone.Item Open Access Assessment of Temperature Variability Effect on Rice Production in Nasarawa State, Nigeria(Department of Environmental Management, Nasarawa State University Keffi, 2020-01-06) Olufemi, Oladeinde Stephen; Joshua, Magaji I.; Ekpo, Salamatu AbrahamThe output of cereal farmlands is imperative for sustainable global food security. Quantity of production from cereal croplands are partly a function of climatic elements and are connected to the pulses of climatic variation. Hence, this paper assessed temperature variability effect on rice production in Nasarawa State, Nigeria. Daily maximum and minimum temperature data were obtained from the Nigerian Meteorological Agency and converted into monthly averages while annual rice production data was obtained from the office of Nasarawa State’s Agricultural Development Programme. Acquired data were analysed using Linear Multiple Regression Model, coefficient of variation and spatial data analysis techniques. Although rice production in the State is being affected by the fluctuations in both minimum and maximum monthly temperature, the later poses grave concern for sustainability of rice production with a negative effect size of -3.145 and a r.opfficient value of -191,324.30 metric tons. This negative Impact of maximum temperature uctuations on rice production indicates that rice production in Nasarawa State is vulnerable to c imate variability with increasing maximum temperature. LGAs in the south senatorial district has more favourable locations for rice production in comparison to those in the North and West districts given that less temperature fluctuation was observed in the former. Government and non governmental institutions as well as individuals planning to establish rice farm project(s) in the study area should consider doing so in the South Senatorial'District in order to avoid the adverse effect of temperature variability.Item Open Access Assessment of Traditional Palm Wine Tapping Practice Effect on Vegetation in Nasarawa State, Nigeria(Department of Environmental Management, Nasarawa State University Keffi, 2019-12-12) Mba, E.H.; Ekpo, Salamatu Abraham; Emmanuel, Ozim Chukwunonso; Olufemi, Oladeinde StephenPalm wine is an alcoholic drink obtained by the natural fermentation of the sap of various type of palm trees, it produced and consumed in various part of the country and beyond. This rich beverage is been used for different traditional practices not only for occasional consumption, so it is of high demand product. The tapping process starts from traditional dealers known as Palm Wine Tappers, that climbs to the top most part of the palm trees, cut it open from the side or middle, or cut down the tree for the liquid sap and this produces lactic-alcoholic-acetic fermentation that is conducted by the lactic acid bacteria (LAB), yeast and acetic acid bacteria (AAB). The tapping process practiced in difference part of the country are; burning/falling, pruning and trimming. They poses a threat to palm trees that serves other environmental, economic, health and nutritional benefits to human and the ecosystem. This practice renders high number of palm trees less productive or dead in a society with no food security, shaky economy, poor environmental practico/=wvareness and tree planting habit. Due to high demand for the product, 4 out of 10 palm ♦rpps a. is 'been converted to palm wine production source, this implies that the palm tree can not palm tre^i f"1 's more °f high economic benefits and also contributes to the shortage of Photos serves as a good absorbent of carbon and gives out oxygen through enviro ^ neSIS Process. a measure that adds value to living organism and reduces warming of the the t ™S ?tud^ recommends proper public awareness especially to the people involve in -nr4 e, Pa'm Wine Tappers" and introduction of more sustainable way of tapping, monitoring and emphasis on tree planting.
