Figure Dam storage, urban and agricultural water use, and rainfall in the Western Cape, 2014-2018
Outline one reason for the variation in agricultural water use, as shown in Figure.
a. more water is needed when rainfall is low / less water is extracted when it rains;
b. more water is needed when (monthly) temperatures are higher (as shown in Figured) due to increased evaporation from soil/plants;
c. (plants require more water when they are growing, so) the greater water use is during the growing season / plants require more water during photosynthesis;
Note: BOD if incorrect season but an appropriate reason is given.
