Coronavirus is currently a huge threat to human health all over the globe. Even though it has no cure yet, it can be contained by proper personal and collective hygiene. This makes access to sufficient clean water supply fundamental and indispensable. Since rural communities tend to be vulnerable to disease outbreaks due to poor standards of hygiene, this study examined the challenges of the rural communities in Enugu West Senatorial District in Nigeria over access to clean water supply and their preparedness to tackle COVID-19 pandemic, following the guidelines from world health experts. The survey showed general awareness of the pandemic in the selected communities. However, 71% neither have access to clean water supply, nor alternative to hand sanitizing agent. A large number of the respondents also acknowledged that availability and accessibility to clean water supply would improve the hygiene culture of the people and as a result curtail the spread of the disease. This study, therefore, recommends that government should intervene by extending water borehole projects and water treatment plants to various rural communities as well as providing maintenance services for non-functional ones.

Climate variability as occasioned by conditions such as extreme rainfall and temperature, rainfall cessation, and irregular temperatures has considerable impact on crop yield and food security. This study develops a predictive model for cassava yield (Manihot esculenta Crantz) amidst climate variability in rainfed zone of Enugu State, Nigeria. This study utilized data of climate variables and tonnage of cassava yield spanning from 1971 to 2012;as well as information from a questionnaire and focus group discussion from farmers across two seasons in 2023 respectively. Regression analysis was employed to develop the predictive model equation for seasonal climate variability and cassava yield. The rainfall and temperature anomalies, decadal change in trend of cassava yield and opinion of farmers on changes in rainfall season were also computed in the study. The result shows the following relationship between cassava and all the climatic variables: R2 = 0.939;P = 0.00514;Cassava and key climatic variables: R2 = 0.560;P = 0.007. The result implies that seasonal rainfall, temperature, relative humidity, sunshine hours and radiation parameters are key climatic variables in cassava production. This is supported by computed rainfall and temperature anomalies which range from −478.5 to 517.8 mm as well as −1.2˚C to 2.3˚C over the years. The questionnaire and focus group identified that farmers experienced at one time or another, late onset of rain, early onset of rain or rainfall cessation over the years. The farmers are not particularly sure of rainfall and temperature characteristics at any point in time. The implication of the result of this study is that rainfall and temperature parameters determine the farming season and quantity of productivity. Hence, there is urgent need to address the situation through effective and quality weather forecasting network which will help stem food insecurity in the study area and Nigeria at large. The study made recommendations such as a
