Dust Bowl

 

Watch the following 2 videos on the Dust Bowl (5 minutes each):

1) What were the causes of the Dust Bowl? What actions were taken to reverse it and to mitigate future occurrences (refer to the two short videos)?

2) Which anthropogenic factors affecting global farming systems do you think are the most critical to resolve in order to achieve global food security by 2050?

Sample Solution

The Dust Bowl was the greatest man-made ecological disaster in the history of the United States. It encompassed a region 150,000 square miles long, across Oklahoma, the Texas Panhandles, and parts of Colorado, Kansas, and New Mexico. A combination of aggressive and poor farming techniques, coupled with drought conditions in the region and high winds created massive dust storms that drove thousands from their homes and created a large migrant population of poor, rural Americans during the 1930s. By 1934, an estimated 35 million acres of formerly cultivated land had been rendered useless for farming, while another 125 million acres – an area roughly three-quarters the size of Texas – was rapidly losing its topsoil. Regular rainfall returned to the region by the end of 1939, bringing the Dust Bowl years to a close.

Seat Exploration Center distributed a review in 2014, named: “Political Polarization in the American Public,” they endeavored to draw an excessively expansive circle around the momentum political talk and polarization inside the country. As displayed in Table #1, they endeavored to shown political polarization inside the party its self, yet not inside the real American public.

Table #1 (Seat Exploration)

The title: “Political Polarization in the American Public,” is a mistaken portrayal of the discoveries. In like manner speech polarization hints a development away from the middle toward the two limits. Which has not occurred in the US. In the event that one ponders polarization in hardliner terms, one would hope to see an expansion in the extents of liberals and conservatives and a reduction in the extent of free electors.

In any case, the American Public Political decision Studies report that the dispersion of American partisanship has been consistent since the re-appointment of Ronald Reagan in 1984. Gallup had the extent of free movers at an unequaled high in 2013.If one contemplates polarization in philosophical terms, one would hope to see a decrease in moderates and an expansion in nonconformists and preservationists. However, the Overall Social Study reports that the dissemination of philosophy in the Unified State has been steady since the mid 1970s. With periodic little special cases, “moderate” stays the modular classification today similarly as it was in the times of Jimmy Carter.

On the off chance that we ponder polarization as far as positions on unambiguous strategy issues, we would hope to see a decrease in the middle and a lumping up of individuals on the super left or right. We don’t have long time series of mentalities toward specific arrangement issues since they rise and fall on the public plan, yet as a general rule, perspectives keep on grouping in the center as opposed to lump up on the limits (nonconformists/moderate). All things considered, we can squabble over the size of the political focus in the US since the response relies upon different approaches to estimating it, yet whichever measure we pick, the end is something similar: the country all in all is not any more captivated than it was an age back, yet there is polarization with in the actual gatherings. Each party’s foundation has honed to conform to these changes. That is important for th
