As the warming climate changes our planet in unexpected ways, there will be populations forced to move. Some migrations will be due to the ocean rising and reclaiming everything from beachfront property to island nations. Some people will be forced to move north as the heat simply makes living unbearable. Other populations will be on the move, as their food production decreases, due to the desertification of once fertile land.
Desertification is the process by which dry, but usable areas, are transformed into a desert. Desertification is not a new phenomenon, having in the past been precipitated by overgrazing and land exhaustion due to poor farming techniques. But one of the major causes of desertification in the 20th-21st centuries is probably climate change. Global warming foments the droughts and forest fires which degrade fertile land. When productive farming areas dry up, people move from rural to urban centers. These migrations into the cities often cause large numbers of unemployed people.
For these digital collages, I used photography from my travels and closer to home, to depict various global environments. In addition, I was recently able to photograph groups of people that I used as silhouettes and patterns, to illustrate the experience of population upheaval.
