The losses are enormous, and the impact is huge. Agriculture and farming have not been spared either. Losses of up to US$780 million in agricultural yields have been recorded in Puerto Rico, for instance.  The recovery efforts are expected to go on for months, if not years.
While it is simply devastating, it is also our new reality. Because of climate change, natural disasters such as hurricanes are expected to happen more frequently, with dire consequences.
Climate-related disasters in Africa
The African continent has also experienced its own share of climate-related disasters. For example, floods across Africa have killed 25 times more people than Hurricane Harvey did.  While chances for Africa to be hit by hurricanes are low, there is still a need to prepare for Africa’s common disasters including flooding.
“Floods across Africa have killed 25 times more people than Hurricane Harvey did.”
Disasters pose significant threats and would slow down and even erode significant steps made towards attaining sustainable development in many of the African countries. Most importantly, these disasters can heavily impact agriculture — the most vulnerable sector which also happens to be the backbone of many African economies. 
Africa should therefore use the grace period Mother Nature is giving the continent to prepare adequate disaster mitigation and preparedness plans that can quickly be rolled out should hurricanes and other climate change-related disasters hit Africa.
We can act ahead of time and not only save lives but also millions of dollars. For instance, according to a study by the Pew Charitable Trusts it pays to prepare for natural disasters.  In addition, according to the United Nations Development Programme, each dollar invested in preparing for disaster results into savings of seven dollars in recovery. 
Lessons from recent hurricanes
So, knowing that disasters are becoming common and that no country is immune, what can Africa do? What can we learn from this very active hurricane season?
First and foremost, preparedness is mandatory. To effectively deal with disasters including flooding and hurricanes, African countries need to prepare in advance. But to prepare, African countries must be able to effectively translate and package the climate-related information to support informed actions. Despite the growing volume of climate information across Africa, there are gaps between the information held in scientific institutions and that which is required to inform decision-making. 
Preparations, among other actions, must be undertaken by disaster preparedness authorities — specialised institutions that tackle disasters by widely disseminating disaster information to all citizens.
African countries can be creative and innovative in how they disseminate information before and after disaster strikes. Delivering messages through mobile phones is one approach that can be used because most African citizens own a mobile phone.
Second, government institutions must liaise with trusted climate forecasting institutions outside Africa such as the National Oceanic and Atmospheric Administration in the United States, and must be networked with similar institutions across Africa. Such global and regional institutional linkages allow for coordinated efforts while making it easy to share information on best practices.
Third, African countries must invest in special disaster insurance schemes and social protective services that are activated only when disasters strike. Food banks and accessible medical and healthcare supplies are also other important services that should be available to citizens when disasters strike.
Insurance schemes and social protective services can also be useful tools that could help citizens of African countries deal with common and frequent disasters including drought and famines that the continent continue to face every year.
“By actively preparing ahead of time and quickly rolling out these action plans, we can reduce the impact these disasters could have.”
Fourth, we must address grassroots poverty. The ability of citizens to deal with and rebound back from any disaster, including hurricanes, is heavily correlated with how vulnerable and poor they are.  Many African citizens are poor and thus, they are heavily affected by disasters. Fighting poverty at the grassroots must be the number one priority of African governments. Majority of the poor in Africa depend on agriculture as a source of livelihood. Therefore, one way science can be used to address grassroots poverty is by ensuring that African citizens have access to agricultural innovations such as improved drought-tolerant crop varieties, climate-smart-farming practices. These innovations could allow agriculture-dependent African citizens to increase their productivity and income and consequently allow them to grow out of poverty.
Most importantly, strong and clear leadership is essential. For example, in the United States, the governor of Texas and Florida, two of the states hit by recent hurricanes, were on the front-line, making sure that citizens knew what they are facing and what they should do. [8, 9] African leaders must follow these great examples.
Finally, the African continent should continue to rely on science, technology and scientific research to prepare and address future natural disasters. Science already does a good job explaining why disasters happen and where risks lie. For some disasters such as droughts, floods and cyclones, forecasts can be made of when they will occur. For example, in 2015, the Famine Early Warning Systems Network used a dataset with more than 30 years of rainfall data to identify African countries including Ethiopia and Nigeria-that were expected to experience drought because of huge rainfall deficits.  These predictions made it possible for these countries, development agencies and others to activate adaptive strategies such as food aid, allowing them to cope with the predicted drought.
Africa does not have to suffer from the brunt of Mother Nature. Disasters are expected to continue happening and we need to cultivate a culture of preparedness — a forward thinking practice. By actively preparing ahead of time and quickly rolling out these action plans, we can reduce the impact these disasters could have on millions of African citizens.
