... (GDPs) ("Agbola andOjeleye, 2007", "FAO, 2005"). The irrationality, however, is that agriculture in this area remains a highly under-developed sector, characterized by an almost total dependency on rainfall; low use of external inputs such as improved seeds and fertilizers; absence of mechanization; and poor Abstract: Ibadan, Southwest Nigeria (Fig. 1A) is highly vulnerable to climate change due its geographic location in the tropical wet-and dry climate area and the strong dependence of its population on rain-fed agriculture. In the period 1981-2010, Ibadan experienced annual mean maximum temperatures ranging from 30.5 O C to 32.5 O C, with an increase of around 0.5 O C every ten ...

... and 1950mm. The major rock types found in the area are the Basement complex rocks of Precambrian age. A detailed analysis of this rock type by "Akintola, 1994" indicates that it can be further subdivided into the meta sedimentary series comprising mainly quartzites and migmatites complex comprising banded gneisses, augen gneisses and mig-matites (Fig. 1B). According to " Gbadegesin and Olabode, 1999", the soils of the Ibadan metropolis belong to the major soil group of ferruginous tropical soils and the soils of the Ibadan region can be further classified into four soil associations. All the four soil associations can be used for producing food crops such as cassava and maize but only ...

... strategies include agriculture, short and long-distance trading, and a variety of urban occupations. Traditionally, very little farming went on within the limits of Ibadan while the belt surrounding the town was used for cultivation of crops. The town land was used primarily for residential and public buildings, markets, shrine and paths (Fig. 1A). Only a small portion of the city land is used for production of vegetable. However, there are lots of pre-urban area within Ibadan were farming is largely the inhabitants occupation. Crops such as yam, sorghum, maize, cassava, cocoyam, Mellon, okra, tomato, pepper and vegetables are the major crops grown in the area. Farming in this ...

... This is further convoluted with the regular drought incidences which characterize the planting season in the forest belt [13] where the south eastern region of Nigeria is found. The increasing mean maximum temperature in the last two decade after 1990's gave a steady variation in rainfall, length of humid period, length of growing period and the onsets of rainfall with noticeable effect, development and growth of crop yield [18][19] .

Rainfall and Temperature are important factors in agriculture especially in Nigeria where rain-fed agriculture is practiced extensively and agriculture contributes to food security and provides employment for urban and rural dwellers. Therefore, climate variability poses a big threat to agriculture by altering the growing season rainfall and temperature, thereby resulting to serious danger in the sustainability of food. This is why all nations of the world are concerned about the effects of climate variability on agriculture. This work therefore, examined the impact of climate variability on growing season rainfall and temperature in Imo State, South Eastern Nigeria. The rainfall and temperature data were obtained from Nigerian Meteorological Agency (NIMET) for a period of 30 years which was analyzed using descriptive statistics, decadal distribution, trend graph anomalies and 5 year moving average. The analysis showed increasing trend in annual mean maximum, minimum temperature and decrease in mean rainfall, The third order polynomial trend shows a decrease in the anomaly of annual mean rainfall (y = -0.0002x4) and a persistent increase in the mean temperature anomaly especially in the second decade (1996-2007).The findings show that there is a notable variability in the pattern of rainfall and temperature which revealed an increase in temperature and decrease in growing season rainfall. This calls for serious attention as people in this part of Nigeria critically depend on rainfall for agricultural practices. It is recommended that government should support the agricultural sector by providing mechanized farming systems such as irrigation and drilling of water borehole in farm sites for agriculture, especially for the rural farmers and create awareness to the farmers on recent trends in climate issues to achieve sustainability of food.

... predicted that for every degree centigrade rise in temperature there will be 7% increase in evaporation and between 1-2% increases of precipitation (Allen, 2015). Subsequently predictions made are now reality as recent records reveal irregular rainfall patterns characterized by sporadic rains, shifts in the onset and cessation dates of rains, and extended periods of dry spells around the tropics (Eruola, Bello, Ufeogbune, & Makinde, 2013;Salack, Giannini, Diakhaté, Gaye, & Muller, 2014). ...
It is a public knowledge that some changes occur in the environment globally which results in increased disease, food shortages, and extreme flooding at various localities during certain periods of the year. A lot of farmers keep lamenting about how their crops were washed away by floods. These farmers suffer from this disaster every year but do not have the solution to their problems except finding a way to adapt and mitigate against this global phenomenon known as climate change. This study, therefore, evaluated the level of awareness and information diffusion of climate change adaptation strategies among formers in Anambra State. The survey method was adopted in carrying out the study and Diffusion of Innovation Theory was the theoretical anchorage. The population of the study was drowned from members of the registered agricultural cooperative societies in Anambra State which is 13,466 with a sample size of 370 which was determined using the Krejcie and Morgan sample size determination table. The study found that farmers in Anambra State level of awareness to information on climate change adaptation strategies is high as they get information through periodic meetings, seminars and workshops even though radio and television have not been effective in disseminating such information especially to farmers in the rural areas. The study, therefore, recommended that various channels of communication, especially radio, should be employed to disseminate information on climate change adaptation strategies in order to reach a broader audience.
... Solomon (2007) observed that every 1 °C temperature rise will result in a 7% increase in evaporation and between 1-2% increase in precipitation. The literature (Allen 2015; Eruola et al. 2013;Gommes and Petrassi 1996;Salack et al. 2014) identified indicators of change in weather patterns which include warmer temperatures, higher evaporation rates, fluctuations in rainfall patterns, sporadic rains, shifts in the onset and cessation dates of rains, and extended dry periods. These and other similar patterns of hot-drier conditions are becoming common in Nigeria. ...
Although agriculture in Nigeria is the major source of income for about 70% of the active population, the impact of agrarian infrastructure on boosting productivity and supporting livelihoods has increased. Climate change and the increasing trend of climate-related events in Nigeria challenge both the stability of agrarian infrastructure and livelihood systems. Based on case studies of two local communities in Plateau state in Nigeria, this paper utilizes a range of perceptions to examine the impacts of climate-related events on agrarian infrastructures and how agrarian livelihood systems are, in turn, affected. Data are obtained from a questionnaire survey (n = 175 farmers) and semi-structured interviews (n = 14 key informants). The study identifies local indicators of climate change, high risks climate events and the components of agrarian infrastructures that are at risk from climate events. Findings reveal that, changes in rainfall and temperature patterns increase the probability of floods and droughts. They also reveal that, although locational differences account for the high impact of floods on road transport systems and droughts on irrigation infrastructures, both have a chain of negative effects on agricultural activities, economic activities and livelihood systems. A binomial logistic regression model is used to predict the perceived impact levels of floods and droughts, while an in-depth analysis is utilized to corroborate the quantitative results. The paper further stresses the need to strengthen the institutional capacity for risk reduction through the provision of resilient infrastructures, as the poor conditions of agrarian infrastructure were identified as dominant factors on the high impact levels.
... In term of food security, climate change could mean that some regions would not be able to sustain current levels of agricultural activity thereby stressing their food security (Eruola et al. 2013;Thornton et al. 2010). Moreover, regions that depend on groundwater irrigation could experience increased stress due to additional demands on their water infrastructure and institutions (Kirby et al. 2017). ...
Sustainable management of groundwater resources to support food security under the potential effects of climate change is an emerging area of research and particularly relevant in the context of Small Island Developing States. Employing three regional downscaled Representative Connection Pathway (RCP 2.6, RCP4.5, and RCP 8.5) emission scenarios that have been linked to an economic evaluation framework, the potential impact of climate change on groundwater scarcity, economic value of groundwater irrigation, food security, and farming livelihoods is investigated. A nonlinear hydro-economic framework, which integrates groundwater hydrology, climate data, land use, economics and institutions, has been applied for the island of Barbados. Results indicate that climate change would intensify the dependency on groundwater irrigation overtime, modulated by climate intensity. The strength of climate change will boost the marginal value of groundwater irrigation, as food price will scale up, presenting negative impacts on food security and reducing farming livelihoods. The climate change would also result in higher cost of producing foods resulting from increased cost of pumping, mainly driven by the effect of meeting abstraction needs for domestic and municipal consumption. Our primary results show that for a small island, sustaining groundwater resources will be a challenging objective to achieve under severe climate change.
