Answer to Problem 10.1CTDQ

The cost of the expansion of soybean farming is increased by 80% from 1996 to 2006 which reduces the area of cultivated land. The suggestion to the Brazilians is that to stop the expansion of soybean farming because it leads to the deforestation which is disastrous to the environment.

Explanation of Solution

About 40yrs ago, soybeans were minor crop in Brazil. However, since 1975 the total area planted with soybeans have doubled about every four years, reaching more than 82 million acres. Hence, over half of the Cerrado has now been converted into vast crop fields.

Theexpansion of soybean farming results inthe grain cultivation, which is increased by 80% from 1996 to 2006 . This has increased, particularly in the area of Cerrado (Brazilian Savannah). However, in the mean time the cattle grazing in almost all Brazilian states (except Amazon, where it is increased by 34% ) is decreased.

The expansion of soybean farming reduced thearea of cultivated land which hascreated a major problem for cattle farmers, thereby they cleared the jungles to create pastures for grazing. These changes weigh major conflicts among farmers for land and environmental problems for Brazilians like deforestation, which can result in unbalanced ecosystem.

As a U.S. ambassador of Brazil, the suggestion to the Brazilians on their farming and grazing policies is to stop theexpansion of soybean farming.

The factor that relates to the advice is deforestation. The increase in soybean farming caused problems for cattle farmers, as they cleared the jungles for pasture grazing, which leads to deforestation. And deforestation causes harm to the environment.

1. Calculate the elevation of the water table at each well location and write the approximate elevation on the line next to each well. Next, use a colored pencil to draw smooth 10-foot contours that show the shape of the water table. (Start with the 1160-foot contour.) Use a pencil of a different color to draw arrows on the map to indicate the direction of the slope of the water table. a. Toward which direction (downward) does the water table slope? b. Referring to the site of the proposed water well, at approximately what depth below the surface should the proposed well intersect the water table? 2. Assume that a dye was put into well A on May 10, 2017, and detected in well B on May 25, 2018. What was the rate of groundwater movement between the two wells, in centimeters per day? (Hint: Convert feet to centimeters.)Velocity:_____________centimeters per day
