Induced Changes

The outbreak and subsequent spread of COVID-19 to the West African sub-region have brought significant changes to the different aspects of our lives and grounded educational and socio-political and economic activities of ECOWAS member states. The pandemic has exposed the poor state of the health systems and shortage in medical supplies and protective gears to cope with the health emergency. In response, strict restrictions were put in place to curb the spread of the virus and these have drastically affected peoples’ lifestyles. However, there has been huge increase in the use of technology in business, education, religion and other activities as people adapt to the changing times in the sub-region. It is the argument of this paper that things cannot return to the way they were before the pandemic, but West African states must strategically plan for the Post COVID-19 era to survive the massive wave of unemployment, socio-economic meltdown and changes in lifestyle. The paper concluded that while the fight against the virus in the sub-region was not collective, post-pandemic recovery must be coordinated, strategically plannedamong member states. It was recommended that the governments should be flexible enough to retain the use of ICT and technology alongside the conventional ways of doing things in the post-pandemic era.

The Impact

We use the International Centre for Theoretical Physics (ICTP) Regional Climate Model (RegCM3) to study the impact of different domain sizes on the simulation of the West African summer monsoon rainfall and circulation features. RegCM3 simulates drier conditions over the default domain (RegCM-D1) and its westward extension (RegCM-D2), much less dryness over the eastward extended domain (RegCM-D3) and excessive wetness in the domain extended northward into the extratropical regions (RegCM-D4). This overestimation is related to the existence of larger source of humidity due to the inclusion of a more significant portion of the Atlantic Ocean and to a weakening of the African Easterly Jet (AEJ), which both favor stronger westerlies advecting moisture towards the land. The best performance is, however, captured in the RegCM-D3 experiment, and this originates from a simulation of moderate westerly moisture fluxes along with a stronger AEJ and occurrences of more frequent African Easterly Waves (AEWs). Therefore, the choice of the domain for regional climate model simulation of the West African summer monsoon rainfall is of critical importance, and caution needs to be taken to account for the main regional forcings including mostly the necessary humidity sources of the tropical Atlantic Ocean and the AEWs genesis region upstream of Sudanese Highlands.
