Obot et al., (2011) studied the trends of rainfall in Abeokuta, Nigeria between 1981-2002. 0 Abstract. A large amount of work has already been carried out by many countries on assessing impacts and vulnerabilities to climate change, as well as considering possible adaptation options. The paper is designed to study the rainfall patterns and its implications in Nigeria. To examine the epochs of above and below normal rainfall, 31-year running MATERIALS AND METHODS Akure is the capital of Ondo State (Figure 4), Nigeria and the major dominating town of Akure South Local Government. STATE, NIGERIA (1990-2009) Akinniran, T. N. 1. Annual Weather Averages Near Ibadan. 0000003742 00000 n Data was collected from the Nigerian Meteorological Agency, Oshodi, Lagos state, Nigeria.

Rainfall in Nigeria is highly dynamic and variable on a temporal and spatial scale. Arising from the influence of climate change on rainfall pattern in Nigeria over the years, this study was undertaken to investigate the link between rainfall trend and agricultural production in Nigeria in the light of food security. It is one of the world's largest arcuate fan-shaped river deltas.. Generally, man’s comfortability depends mostly on the weather condition which largely depends on radiation from the sun and rainfall .Over the years, different kinds of radiation are considered. This research aimed to examine the trend of rainfall in Akure using 50 years rainfall data. In Nigeria, studies on rainfall and their implication for flood frequency have been restricted to the southern parts of Nigeria, little or no attempt has been made in the literature to study the implication of recent changes in rainfall pattern on flood frequency in northern Nigeria despite increase frequency of floods in this region, and this is where this study derives its relevance. growing need to study the rainfall pattern, and also frequency of the heavy rainfall events. In this work, the non-parametric Mann-Kendall test is used to test for significant trend in rainfall in Nigeria through Nigeria and it is the grain belt of the country populated by small scale subsistence farmers and nomadic livestock herders.

In Nigeria, the climate is tropical, semi-arid in the far north, and progressively rainier as you move southward. %%EOF Rainfall data from twenty Nigeria stations, Sea Surface Temperature.tremendous crop failure whenever there are significant changes in rainfall pattern. For instance, Ifabiyi et al.,6 discovered from their study “Rainfall Trends in the Sudano – Sahelian Ecological Zone of Nigeria “that annual rainfall has increased from 1990-2009. Rainfall Pattern in Nigeria It is a common believe that all water on the earth comes from the rain and stored as surface water such as rivers, ponds, oasis, or underground water as spring and water table etc. This study was checked annual average ... rainfall in northern Nigeria for the years 1951-1975. �h�Yd) �d�```qk 25@���P4��\ F�[@Z����*1�p It decreases from the south to the north, the rainfall comes late and not evenly spread across the rainy season and consequently has adverse effect on agricultural activities (Iloeje, 1981).

This has taken a more pronounced dimension due to climate change. Although many findings considering Annual rainfall varies in Nigeria. This study examines the length of the growing season in Nigeria using the daily rainfall data of Ikeja, Ondo, Ilorin, Kaduna and Kano. �)� The variability of rainfall and the pattern of extreme high or low precipitation are very important for agriculture as well as the economy of the state. Department of Agricultural Economics, LAUTECH, Ogbomoso, Oyo State . Annual rainfall totals, growing season rainfall totals and annual raindays of 27 Nigerian meteorological stations with varying lengths of records from 1903 to 2012 were collected from the Nigerian Meteorological Agency (NIMET).
