Yemen has suffered flash floods and unusual amounts of rainfall recently. These phenomena are not new, but they may be increasing because of climate change, which increases water vapor in the atmosphere. Locusts flourish in wetter top soil.
Yemen is an agricultural society and much of the population is food insecure to begin with. Climate change threatens to depopulate the place and force mass migration to Saudi Arabia (not friendly to undocumented aliens).
The International Food Policy Research Institute writes:
“The new IFPRI Discussion Paper “Climate Change and Floods in Yemen” by Manfred Wiebelt, Clemens Breisinger, Olivier Ecker, Perrihan Al-Riffai, Richard Robertson , and Ranier Thiele assesses the impact of climate change on Yemen’s economy and food security. The effects of climate change are extremely salient considering Yemen’s high levels of food import dependency, food insecurity, and poverty. An estimated 43 percent of Yemenis live in poverty, and 32 percent of the population does not have access to enough food.
The paper shows that climate change will have a negative impact of the country’s future development. The number of poor and food insecure people will increase, it argues, as climate change causes higher food prices on the global level and a long-term reduction in agricultural yields, and potentially increases the frequency of flooding.
Global commodity price changes will threaten the country’s already vulnerable populations. Although higher global prices will raise agricultural GDP, they will lower Yemen’s overall GDP growth and decrease household incomes.
Climate change will induce considerable economic losses and spikes in food prices…”
