A review of effects of climate change on Agriculture in Africa
Samuel Asante Gyamerah, Dennis Ikpe
Currently, agriculture in Africa contributes only a tenth to global Green House Gas (GHG) emissions from agriculture. Despite its relatively low contribution to GHG, a conundrum of…
Two critical times for the SIR model
Ryan Hynd, Dennis Ikpe, Terrance Pendleton
We consider the SIR model and study the first time the number of infected individuals begins to decrease and the first time this population is below a given threshold. We interpret…
An eradication time problem for the SIR model
Ryan Hynd, Dennis Ikpe, Terrance Pendleton
We consider a susceptible, infected, and recovered infectious disease model which incorporates a vaccination rate. In particular, we study the problem of choosing the vaccination r…
Hedging crop yields against weather uncertainties -- a weather derivative perspective
Samuel Asante Gyamerah, Philip Ngare, Dennis Ikpe
The effects of weather on agriculture in recent years have become a major global concern. Hence, the need for an effective weather risk management tool (i.e., weather derivatives)…
Crop yield probability density forecasting via quantile random forest and Epanechnikov Kernel function
Samuel Asante Gyamerah, Philip Ngare, Dennis Ikpe
A reliable and accurate forecasting model for crop yields is of crucial importance for efficient decision-making process in the agricultural sector. However, due to weather extreme…
