According to UN Population Division data, as charted below for Egypt, Syria and Yemen (Libya missing in chart) the population in various key countries doubled twice in little over 50 years.
In 1950 a total of 29.8 million people lived in the four countries. By 2010 this had increased to 132.6 million – a rise of 345 percent (or in other words increased by a factor 4.45).
Almost 8 times as many people, in one century..?
According to UN forecasts (medium variant) the combined population of Egypt, Syria, Yemen and Libya might rise to 191.5 million people by 2030 and 243.6 million people by 2050. That represents an increase of the total combined population in these countries by a factor 8.17 (or +717 percent) in 100 years time.
Yemeni population almost tripled in 30 years before uprising(!)
Syria and Yemen have seen a faster population growth in recent years than Egypt and Yemen. In Syria the population grew by a factor 2.3 between 1980 and 2010, from an estimated 8,956,000 to 20,721,000 people. In Yemen the population increased with 193 percent, from an estimated 8,059,000 to 23,592,000.

Increasing droughts + continued population growth = ?
In most of the mentioned countries Arab spring uprisings started in January 2011. Other proclaimed drivers of this revolution (next to possible cultural and technological changes [turns out even we are on Twitter these days!]) have been fluctuations in food and energy prices and most notably prolonged drought in Syria. Climate change will likely exacerbate droughts in the area over decades to come – increasing the potential effects of the forecast demographic trends.
Clearly what the world needs is policy focusing on these large-scale driving trends. The COP21 UNFCCC climate conference of December 2015 in Paris is one the most essential arenas for international cooperation in this field.
