Item CLIMATE CHANGE AND RICE PRODUCTION(Faculty of Agricultural Sciences of the Sabaragamuwa University of Sri Lanka, 2017) Rhoda Mojisola, Olanrewaju; Tilakasiri, S.L.; C., OsoThe paper explores the climate effect of rice produce in Ekiti State Nigeria. Climate data was obtained from the archive of the Nigerian Meteorological Station, Oshodi, Nigeria. The Rice data was obtainedfrom Ekiti State Agricultural Development Project (A.D.P) The climatic parameters are rainfall amount, rainfall frequency, maximum and minimum temperature while rice yield data include land devoted to rice cultivation, rice production and yield. The data covered the period of 5yrs between 2007 and 2011. The climate data were grouped based on the rice cropping calendar of the study area into the pre-planting (Feb), the planting season (March-mid April), the period of growth (mid April- July) and the period of harvest. The data were summarized using statistical tool of mean, Correlation and regression were used to find the strength of relationship while the most critical climatic variable(s) for rice was identified using factor analysis. The result showed that increase in land devoted to rice did not bring corresponding increase in rice yield. Increase in rainfall amount and frequency during the period shortly before planting and during planting seems to be very important for rice yield. Minimum temperature correlates highly with yield during the period of planting. Mild positive relationship exists between yield and temperatures (maximum and minimum). Temperature is most critical during harvest as both maximum and minimum temperature exhibited a high positive relationship of 0.82 and 0.66 respectively.Item COMMUNITY PERCEPTION OF DEFORESTATION AND CLIMATE CHANGE IN IBADAN(University of Ruhuna, Sri Lanka, 2018) Rhoda Mojisola, Olanrewaju; Tilakasiri, S.L.; Bello, F.B.The studies of urban climate are attracting significant attention in the present dispensation due to the global impacts of climate change, induced mostly by anthropogenic activities. This study examined the community perception of deforestation and climate change in Ibadan, Oyo State. Data for this study were obtained from both primary and secondary sources. A total of 400 questionnaires were administered randomly across the II Local Government Areas using purposive sampling technique while 365 were retrieved and analyzed using descriptive statistics of means and percentages. Deforestation data were derived from the LandSat imagery sourced from National Space Research and Development Agency (NARSDA) and constitute the secondary data. Supervised classification technique was used for image classification. Results obtained revealed that majority of the people (77) are familiar with the concept of climate change and among them 39 and 29 of the respondents perceived variability in temperature and rainfall respectively as the two major causal factors of climate change. The result further shows that 95 per cent of the respondent agreed that deforestation account mostly for the incidence of climate change. However, 40 of the respondents described the impacts of deforestation on climate change as severe. Meanwhile, 37 of the respondents believed that afforestation and mixed farming are the most suitable solutions to address the problem of climate change. Based on the classification technique adopted, four types of Land use/Area cover emerged in the study area. Based on the findings of the present study, it can be recommended the use of environment friendly sources of energy such as solar vehicle, bio-fuel and promotion of green environment (tree planting) among others to prevent severe impact of climate change.Item ENVIRONMENT AND DEVELOPMENT(STAMFORD LAKE (PVT) LTD., 2012) Tilakasiri, S.L.; Raheem, U.A.; Rhoda Mojisola, OlanrewajuThe accelerated pace of development the world over is creating enormous challenges to the environment through eco-system degradation and natural resource depletion. These resources also play crucial roles in ensuring adequate food and water supply as well as other life supporting services to the ever increasing world population. This chapter examines the degenerating relationship between man and nature consequent upon technologies of development in different countries. It reviews the major environmental paradigms related to development with particular references to developing countries. Using the concepts of sustainable development, Global Environmental Change and Global Warming among others, the chapter canvasses for a deliberate effort by national governments in developing countries to redirect development strategies towards a sustainable path by taking appropriate cognizance of the damaging effects of development efforts. Thus, the chapter recommends controlled urbanization, planned industrialization and eco-friendlyagriculture as development options towards sustainable development.Item GLOBAL WARMING AND CLIMATE CHANGE(STAMFORD LAKE (PVT) LTD., 2016) Tilakasiri, S.L.; Rhoda Mojisola, Olanrewaju; Salami, A.A.Item An overview of Nigeria universities’ presence on social media platform(University of Sri Jayewardenepura, Sri Lanka, 2017) Amali, I.O.O; Bello, M.B.; Akintola, M.; Tilakasiri, S.L.This study is an online survey on the presence of Nigerian universities on social media platforms. The purpose of the paper was to examine the level of presence of Nigerian universities on five social media platforms which include: Face book, Twitter, YouTube, LinkedIn and Google+. Three research questions were generated and one null hypothesis was formulated for this study. In the methodology, the internet served as the primary source of data, while Nigerian universities’ websites were used as secondary sources. All 129 accredited Nigerian Universities by the National Universities Commission were sampled for this study. Descriptive statistics (Percentage, Mean Rating and Standard Deviation) were used to answer research questions 1 and 2 while inferential statistics (Chi-Square) was used to test and analyse the null hypothesis. Report of Micaiah (2014) on Social Media Awareness in Nigeria Education which states that Nigerian universities’ presence on social media is minimal, was used as a guide; its methodology and data were also adapted for this study. The result showed that Nigerian Universities’ presence on social media platforms was 19% which is below par, compared to the unprecedented social media user base among Nigerian university students. In the analysis of the hypothesis, it was revealed that university ownership does not significantly determine the presence of Nigerian universities on social media platforms. It thus recommends that universities in Nigeria should as a matter of urgency, create a central unit of social media services to manage all necessary social media activities of their institutions, and to heighten Nigerian Universities’ presence on social media platforms which would create a mindset on educational goals and attainment among academics and students in Nigeria.

The objective is to draw attention to the collaborative mandates ascribed to teachers to ensure fulfilling their obligations in the successful implementation of the policy. This study addresses the educational and social relevance of pre-primary education in Nigeria, especially in respect to cognitive, emotional and social development of Nigerian children. In view of its societal relevance, this study advocates for a desirable and necessary educational process and provides guidelines on teachers preparation, supply and motivation which are desirable for ensuring successful implementation of pre-primary education policy in Nigeria. It also identified teachers’ constraints, show the way forward that would ensure that teachers achieve their mandates in the successful implementation of the policy objectives. A study like this is relevant to the understanding of the objectives of pre-primary education as contained in the National Policy of Education and could contribute to the process of developing a more effective approach to address the problem of achieving the objectives of the policy in Nigeria. It recommends a strong commitment of federal, state and local governments education authorities to facilitate the successful implementation of the policy objectivesItem WATERSHED MANAGEMENT AND SUSTAINABLE DEVELOPMENT IN NIGERIA(Faculty of Graduate Studies, University of Sri Jayewardenepura, Sri Lanka, 2015) Kayode Ademola, Iroye; Tilakasiri, S.L.Nigeria environment today is being confronted with myriads of ecological problems, which have resulted in serious degradation of many watersheds. These environmental problems are occurring at increasing and alarming rates and are being accelerated by man's activities such as urbanization, increased agricultural activities, deforestation, bush burning, civil construction works, over-grazing and poor water resource management among others. These land-use transformation activities most times disrupt the natural processes of a basin thus triggering the occurrence of accelerated erosion, sedimentation, slope failure, flooding, drought, desert encroachment and pollution. Response to these problems in the recent past in the country has not been good, hence this paper. Effective and efficient basin management is a perquisite for reduction of natural disasters and achievement of sustainable development.
