Effects Of Global Climate Change On Nigerian Agriculture: An Empirical Analysis, Apata T. .G Jun 2011

Effects Of Global Climate Change On Nigerian Agriculture: An Empirical Analysis, Apata T. .G

CBN Journal of Applied Statistics (JAS)

This paper presents an empirical analysis of the effects of global warming on Nigerian agriculture and estimation of the determinants of adaptation to climate change. Data used for this study are from both secondary and primary sources. The set of secondary sources of data helped to examine the coverage of the three scenarios (1971-1980; 1981-1990 and 1991-2000). The primary data set consists of 900 respondents’ but only 850 cases were useful. This study analyzed determinants of farm-level climate adaptation measures using a Multinomial choice and stochastic-simulation model to investigate the effects of rapid climatic change on grain production and the …


Adaptive Responses To Flooding Incidents In Ilorin, Kwara State, Nigeria, Habiba I. Jimoh, Kayode A. Iroye Jan 2011

Adaptive Responses To Flooding Incidents In Ilorin, Kwara State, Nigeria, Habiba I. Jimoh, Kayode A. Iroye

Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria

Incidents of floods which are mainly caused by changes in landuse is fast becoming a city life experience in Ilorin as in most urban centres in Nigeria causing untold hardships and sometimes loss of lives. This extreme hydro-meteorological event is also being exacerbated by climate change which thus calls for adaptive response by residents towards reducing its risks, hence this study. Data used were generated from direct field measurements and questionnaire administration. Descriptive statistics and cross tabulations were used in analyzing the data. Results obtained indicate that most respondents use a wide range of non-structural adaptive response to flood. The …

Background: In recent years the Later Stone Age has been redated to a much deeper time depth than previously thought. At the same time, human remains from this time period are scarce in Africa, and even rarer in West Africa. The Iwo Eleru burial is one of the few human skeletal remains associated with Later Stone Age artifacts in that region with a proposed Pleistocene date. We undertook a morphometric reanalysis of this cranium in order to better assess its affinities. We also conducted Uranium-series dating to re-evaluate its chronology. Methodology/Principal Findings: A 3-D geometric morphometric analysis of cranial landmarks …
