How is food security threatened by a natural disaster?

Most scientists agree that there is a connection between climate change and natural disasters. Once again we are experiencing extreme weather in the United States. From drought-stricken regions of the Northern Plains to the ravages of Hurricane Harvey, large-scale disasters often disrupt, if not destroy, food security, affecting the poorest families the hardest.

In today’s issue of The Guardian, Climate Change reporter George Monbiot states:

It’s a fact: climate change made Hurricane Harvey more deadly. This is a man-made climate-related disaster. To ignore this ensures our greatest challenge goes unanswered and helps push the world towards catastrophe.

To claim there is no link between climate breakdown and the severity of Hurricane Harvey is like claiming there is no link between the warm summer we have experienced and the end of the last ice age.

We know that the severity and impact of hurricanes on coastal cities is exacerbated by at least two factors: higher sea levels, caused primarily by the thermal expansion of seawater; and greater storm intensity, caused by higher sea temperatures and the ability of warm air to hold more water than cold air.

Although the services and people of South Texas had more warning and time for preparedness than those hit by Katrina, the magnitude of Hurricane Harvey is still taking a toll after 8 days from not only the impact of the hurricane itself but also the nonstop rain in its aftermath. Flooding caused by the rain is imminent or has happened from the reservoirs that are already over capacity.

According to NASA:

Rainfall estimates for the period 21 to 28 August 2017 showed the accumulated effects of all of the rain from Harvey to date.

  • 20 inches from the coast near Galveston Bay to in and around the Houston area as a result of the near continuous stream of showers and rain being drawn over the coast in rainbands on the eastern side of Harvey’s counter clockwise cyclonic circulation.
  • 10 inches were calculated to have fallen from western Louisiana all the way to near Corpus Christi on the coast.
  • The result has been widespread, massive flooding across the region and brings back memories of Tropical Storm Allison, which dropped up to 40 inches of rain in Texas back in 2001 and caused devastating flooding in the Houston area.

Climate disasters deplete short-term food supplies, but with the help of relief efforts, those stocks can be replenished.

What about food production in the immediate future? Over the following months and years?

In the wake of disasters, rebuilding food production capabilities and distribution is essential to help people gain access to safe and nutritious food. Right now stranded people have run low or out of food in the affected areas. In the long term, we need to be sure we have rebuilt the agriculture infrastructure in the area.

Texas is one of the top the top 10 agricultural producing States in the US. It ranks #1 in acres of farmland of all the states. Almost 1/2 of the state’s total agricultural production is cattle. Other livestock products are chickens, hogs, and dairy products. Sorghum, corn, and wheat are among the top 5 cash crops. Many fruits are produced in Texas including watermelons, grapefruits, and cantaloupes. Important Texas vegetables include onions, potatoes, and cabbages. Texas is the #1 producer of cabbages among the states. Texas is also a leading producer of pecans.

With Texas contributing such a substantial amount of products to the food supply, in the short term we will likely see a rise in food prices. This will affect everyone in the USA and in turn, other countries that depend on the USA for grain and other food staples.
