“…The temperature distribution is nearly similar to that of the rainfall with higher temperatures in the southern and eastern parts of the study area. This concurs with the fact that rainfall decreases as one moves hinterland away from the southern coast of the country holds here (Odekunle and Adejuwon, 2007;Ezeh et al, 2016). Similarly, the lower temperatures in the northcentral part of the study area could be attributed to the moderating effect of the higher plateau over there exemplified by the Udi-Okigwe-Awka-Orlu escarpment.…”

The study assessed the variabilities in climate and key factors of rice production in southeastern Nigeria. Trend analysis and spatial interpolation expressed the spatiotemporal variabilities in the climate and rice yield. Copies of the questionnaire were used to assess four hundred and eighty farm households from 12 local government areas. Other analyses included descriptive statistics, logistic regression, and Productivity Index. The farmers’ socioeconomic characteristics show that the majority (62% of them are young males aged between 30-39 years. Over 80% of them were married while about 72% has household sizes between 5-9 persons. A greater proportion (54%) of them generate between N240,000.00 (578 USD) to N480,000.00 (1156 USD) annually. About 96 % have a farming experience above 10 years, while 50% have basic education (primary education). Logistic regression shows that sex (0.02), category of the farmer (0.00), age (0.03) (0.00), educational qualification (0.02) (0.00), membership of cooperative society (0.00), extension workers’ visit (0.03) were the statistically significant determinants of rice productivity in the area. The area experiences significant rising temperatures and declining rainfall. This trend is more obvious in Ebonyi state. Study results acknowledge the necessity of an enabling environment for rice farming through adequate rural infrastructure, improved rice varieties, access to information, and improved government policies, programs, and interventions to accommodate non-ADP rural rice farmers in order to enhance rice production against the unwanted climate changes

“…The increasing of dry spell duration revealed was also indicated by New et al [3] for West Africa. Likewise rainfall during the months of June to September appears to have witnessed declining trends over 1961-1993 in Nigeria [54]. In Benin, the work on climate indices made by Hountondji et al [21] showed that only the annual total precipitation, the annual total of wet days and the annual maximum rainfall recorded during 30 days present a significant decreasing trend while the others rainfall indicators appear to remain stable for the period 1960-2000.…”

This study analyzed the trends of extreme daily rainfall indices over the Ouémé basin using the observed data from 1950 to 2014 and the projected rainfall of regional climate model REMO (REgional MOdel) for the period 2015-2050. For future trends analysis, two Intergovernmental Panel on Climate Change (IPCC) new scenarios are considered, namely RCP4.5 and RCP8.5. The indices considered are number of heavy rainfall days, number of very heavy rainfall days, consecutive dry days, consecutive wet days, daily maximum rainfall, five-day maximum rainfall, annual wet-day total rainfall, simple daily intensity index, very wet days, and extremely wet days. These indices were calculated at annual and seasonal scales. The Mann-Kendall non-parametric test and the parametric linear regression approach were used for trends detection. As result, significant declining in the number of heavy and very heavy rainfall days, heavy and extremely heavy rainfall, consecutive wet days and annual wet-day rainfall total were detected in most stations for the historical period as well as the future period following the scenario RCP8.5. Furthermore, few stations presented significant trends for the scenario RCP4.5 and the high proportion of stations with the inconsistence trends invites the planners to get ready for an uncertain future climate following this scenario.

“…Odekunle and Adejuwon [26] asserted that there had been a decline and persistent decrease in rainfall in Nigeria over the last few decades. This is consistent with Odjugo [21] claim that there is an increase in temperature and a reduction in the amount and duration of rainfall.…”

Climate change remains a pivotal area and a persistent challenging issue for deliberation among the nations of the world. Most especially in a country like Nigeria, where fossil fuel remains a pivotal source of socio-economic development and well-being of the society. Transforming the Nigeria electricity sector into a source for reducing the country’s carbon emission remains a significant challenge to policymakers, i.e. the Government. This is attributed to the fact that the nation’s primary energy sources come from traditional biomass and fossil fuel such as coal, and natural oil and gas, which has contributed significantly to the level of carbon emissions. In this paper, we explored and identified the potentials, barriers and option for renewable energy in Nigeria. The findings of the review revealed that the Nigerian electricity sector is crucial to reducing the carbon emission generated in the country. Likewise, it is of no doubt that Nigeria is endowed with a different mix of renewable energy sources. Hence, exploring and developing these renewable energy sources will aid the effort of the government in reducing the country’s input to the global carbon emission, instrumental to the socio-economic development of the country and improved well-being of the society at large. Also, policy recommendations to foster renewable energy development were identified.
