Item Development of Draught Early Warning System (DEWS) in Nigeria: A Review of Progress, Challenges and Future Directions(ICEC, 2025) AJiboye, Johnson Adegbenga; Ofeoshi, C. I.; Adesiji, A. R.; Saidu, M.Drought Early Warning Systems (DEWS) are important tools for reducing the impact of drought on agriculture, water resources, and food security. This review explores drought trends in Nigeria, assessing the progress, challenges, and future directions of DEWS development. Analysis of past drought occurrences reveals that Nigeria has experienced notable drought episodes in 1914, 1924, 1935, 1943, 1951-1954, 1972-1973, and 1991-1995, with the driest decades recorded between 1970 and 1990. The increasing trend of drought events is linked to climate change, land degradation, and poor water management. Nigeria's primary DEWS, managed by the Nigerian Meteorological Agency (NiMet), employs indices such as the Standardized Precipitation Index (SPI) and the Palmer Drought Severity Index. However, these systems face significant challenges, including data gaps, limited technological integration, and inadequate community participation. An analysis of past studies shows advancements in satellite-based vegetation health indices, climate modelling, and machine learning algorithms. However, DEWS effectiveness is hindered by institutional weaknesses, data limitations, and insufficient stakeholder engagement. Key challenges include governance, coordination, funding, and capacity building. Future research should focus on intègrating local knowledge and indigenous practices, developing more complex and integrated DEWS models, improving data quality, and enhancing communication strategies. This review aims to inform policymakers, researchers, and practitioners about the need to strengthen DEWS to support drought resilience and sustainable development in Nigeria.Item Impact of Climate Change on Information Service Delivery in Selected Libraries in Kwara State(Proceedings of the Nigerian Library Association, Delta State Chapter Conference, 2021) Abduldayan, F.J.; Oyedeji, G. O.; Abubakar, A.; Abduldayan, A. H.The study examined the impact of climate change on service delivery in the National Library of Nigeria, Ilorin; University of Ilorin Library; and National Stored Products Research Institute Library, Ilorin. The study was guided by five (5) research objectives and questions that sought to identify the level of awareness of library staff on climate change, the impact of climate change on information resources and library building, available plans and preventive measures against the impact of climate change on the libraries, and challenges faced by libraries in combating the effect of climate change. The population of the study was eighty-seven (87), hence, total enumeration was used for the study. Seventy-four (74) copies of questionnaire were filled, returned and used for the analysis. Questionnaire and observation checklists were used as instruments for data gathering. Simple percentages and tables were used for data analysis and presentation of findings. Findings revealed that the majority of the respondents are aware of environmental factors such as temperature, relative humidity, light, air pollution, greenhouse gases and global warming which affect libraries, books and information resources. However, climate change has the highest negative impact on books in the libraries studied. Climate change also affected the walls of library buildings, ventilation and temperature. The following recommendations were made among others: training and workshops should be organized for library staff on climate change and its effects on libraries. Continual rehabilitation of dilapidated library buildings to control the impact of climate change and finally, procurement of modern technological gadgets to curtail changes in climate.
