The Causes and Consequences of Droughts: From Climate Change to Dust Bowls
TLDR Droughts are natural disasters exacerbated by human activity, particularly the use of fresh water for agriculture. Climate change, specifically the increase in CO2, contributes to drought conditions. Effective measures to combat droughts include raising awareness through electronic billboards and implementing government programs like the New Deal to prevent another Dust Bowl.
Timestamped Summary
00:00
Droughts are a serious natural disaster and can be considered a form of a natural disaster.
05:05
Droughts are natural and become natural disasters when humanity applies itself to them, and the global supply of fresh water is mostly used for agriculture, exacerbating droughts and leading to serious consequences such as food riots and starvation in poorer countries.
09:56
Drought occurs when there is not enough rain to sustain the ecosystem, and factors such as high pressure zones, air pollution, and wind shifts can exacerbate the problem.
14:58
El Nino and La Nina, which are caused by the Pacific decadal oscillation and the Atlantic multi decadal oscillation, can lead to extreme weather events like floods and droughts, and when combined with other factors, can create wetter or drier than average conditions in different parts of the world.
19:51
The severity of a drought can be categorized into different stages, starting with meteorological drought where rainfall is compared to previous years, followed by agricultural drought when farmers start to notice, then hydrological drought when water levels visibly decrease, and finally socioeconomic drought when government restrictions are put in place due to the impact on the economy.
24:26
Climate change, specifically the increase in CO2 in the atmosphere, is believed to contribute to drought conditions by creating high pressure areas and preventing air currents from forming.
30:07
Climate change, specifically the increase in CO2 in the atmosphere, is believed to contribute to drought conditions by preventing air currents from forming and creating upwelling action that generates rain.
34:54
One effective program to combat drought conditions was the use of electronic billboards to raise awareness and encourage water conservation by showing the low water levels in shared reservoirs and the potential consequences of running out of water.
39:58
The dust bowl was caused by a combination of overproduction of wheat, a recession, and a drought, resulting in the loss of topsoil and massive dust storms.
45:07
The federal government, particularly FDR with the New Deal, implemented measures such as the creation of the soil conservation service and buying land to prevent another dust bowl from happening again.
50:16
The federal government created soil conservation districts and provided subsidies to small farmers in order to prevent another Dust Bowl, but as farms were consolidated into larger operations, the subsidies became less effective and a waste of money.
