Subsequent to the fall of the Harappan civilization, the Vedic literature in Sanskrit, dating back to 1000-2500 BC, contains several references to methods of tilling soil, collecting water, predicting rainfall, and urging farmers to observe good land husbandry (Wasson 2006). The importance of soil conservation in the rise of the Mayan culture (the Mayans cultivated crops like corn, beans, and squash in Central America for millennia) cannot be overemphasized (Piperno and Pearsall 1998).
