Explain how the use of agricultural chemicals contributed to the change in rice production.
(Ap Human Geography)
Answers
Answer:
Herbicides and insecticides appeared to be the most frequently used pesticides for both crops. Amino phosphonates (mostly glyphosate) represented the most used herbicides (45 % for rice up to 89 % for vegetables). Pyrethroids appeared to be the most used insecticides (accounting for 90 % of all the insecticide use reported). Approximately 75 % of respondents had not been to school and do not understand product labels. Only about 45 % of farmers respect the recommended pesticide dosage and about 10–15 % of pesticides used for rice and vegetable, respectively, are not recommended for these crops. As per WHO criteria, the mosquito local populations from the two localities were resistant to three of the four insecticides tested, as mortalities were less than 35 % for deltamethrin, DDT and bendiocarb. Higher susceptibility was observed for malathion, although the population was considered resistant in Dabou (80 % mortality) and susceptible in Tiassalé (98 % mortality). With the exception of glyphosate, residues from each of six chemicals tested for were detected in each of the sites visited in the two localities.

From the map that we have here the use of pesticides have different effect on the change in rice production in different regions of the world.
In the area that is marked black in the map, the use of pesticide led to a raise in the tons of rice produced from 1.0 to 1.6 tons.
In the area that is grey, the use of pesticide led to an increase in the tons of rice produce from 0.5 tons to 1.0 tons. Same increase can be observed in the area that is under the grey area.
While in the white area, there was no change that was noticed in the yield of rice when pesticides where used.

Answers
Answer:a
Explanation: the other answer choices aren’t universal and can be different for each farm.
The most often cited environmental benefit of the eat-local movement is that less fossil fuel is used in transporting food to market. Thus, the ideal selection is option a.
What are the environmental benefits of buying local products?Through reduced food miles or even transportation of any other goods, shopping locally can help reduce carbon emissions and air pollution. Additionally, to benefit the local economy, it is beneficial for the environment.
When food is produced and consumed locally, it reduces the need for long-distance transportation, which in turn reduces the amount of energy and fuel required to transport food. This leads to a reduction in greenhouse gas emissions, which can help to mitigate the impacts of climate change. While the other options listed may also be environmental benefits of the eat-local movement, they are not typically cited as frequently as the reduction in fossil fuel use.
Thus. the ideal selection is option a.
