Focused Group Discussions (FGDs) were undertaken in 18 communities in six local government areas in Niger State spread across the three agricultural zones in the State to validate the impact of climate change and variability. The climate data was analyzed with the aid of charts. Results showed a generally rising trend in both temperature and rainfall across the State. It shows that rainfall is not only more variable, but its onset and cessation patterns have shifted and its occurrence very inconsistent. Linear relationships between climatic variables and the major crops showed moderate to strong positive and negative relationships. However, when crop yields were regressed with the climate variables, only maize (.032), bambara groundnut (.029) and groundnut (.007) were very significant at .05 confidence level (95%). The policy implication of this finding is the need to provide the farmers with local climate information and the need for vigorous pursuance of the development of high yield crop varieties better suited to changing climate conditions in the Guinea Savanna ecological zone by research institutes and other relevant agencies.</p> I.

This study examined the waste situation presently in Port Harcourt as well as the constraints to environmental management in Port Harcourt and it was reported that most people have adopted wrong attitudes that impacts on the environment knowingly or unknowingly and hence these overtime have become a way of life that have overtime crept into the society as a lifestyle not minding its attending consequences and as a result puts a limitation to managing environmental challenges. The study also examined environmental and health implications of poor attitudes to waste management and it was discovered that arising from poor attitudes to the environment, the quality of the environment has deteriorated and that this have helped in increasing the spread of communicable diseases among residents and also flooding and other environmental challenges. The study however stated that poor air quality affect human health through adverse health conditions which affects the gastrointestinal linings, respiratory tract diseases and other&nbsp; &nbsp;ill health. Arising from the study enlightenment campaign for all at schools, churches, &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;communities and Local Government levels, adoption and integration of environmental education into the present day school curriculum at all levels and the enforcement of environmental laws&nbsp; on indiscriminate waste disposal will serve as a panacea for effective waste management in&nbsp; &nbsp;Port Harcourt.</p> G.
