Understanding the Past to Solve Today’s Problems: Adaptability to Climate Change among Diverse African Populations

There is an old adage that goes, “Those who do not understand the past are doomed to repeat its mistakes.”  This rings true not only within historical contexts but others, as well, particularly concerning contemporary issues, such as contemporary climate change.  A group of scholars recently published their study wherein they successfully argued for a holistic understanding of the history of subsistence strategies in order to best aid contemporary societies.  They used African populations as their evidence.  These chose these populations not specifically due to the data available to analyze and test their ideas, but because contemporary African populations are most sensitive and impacted by modern climate change, necessitating a viable solution to the contemporary problems they are currently facing.

 

In their study Phelps et al. examined isotopic, ecological, and archaeological data from African populations that existed over the past 11,000 years.  They noted that near the beginning of this temporal span (as in 11,000 years ago) the African continent was much wetter and tropical, and over time it became drier and more arid.  By examining the isotopic data, which showed peoples’ diets over time, as well as archaeological data to help infer subsistence strategies of said people, they were able to identify how African populations were best able to sustain themselves in the face of climatic shifts. 

 

They ultimately reached the conclusion that those populations that were most resilient were those that utilized a mix of subsistence strategies, not just one.  Africa populations that engaged in a combination of farming, foraging and hunting, fishing, and herding/pastoralism were better able to survive during long periods of environmental changes and uncertainty. 

 

The reason this information is important is because it can be used to assist not only contemporary African populations but other populations across the world as climate change continues.  "If we want climate solutions and global environmental change solutions to work, they need to be rooted in an understanding of the way that people have been using available resources throughout time," said Phelps.  This makes sense as it acknowledges people’s familiarity with their own environments and ways of surviving within them without drastically transforming their ways of life during stressful periods.  It also draws upon successful strategies that worked in the past and most likely will continue to do so in the present, thereby allowing for informed decision making that will increase the likelihood of successful implementation.
