What were the three main environments that were suited to tillers? Describe how tillers adapted the environment for agriculture and what crops were supported in each

Question

What will be an ideal response?

Answer 1

A. Swampland
1) swamp soil is rich, moist, and easy to work with simple technology
2) rice was the main crop
3) swampland cultivators can adapt the land for other crops by dredging earth and by building up mounds for planting when rice is unavailable
a) they farm water-dwelling creatures and plants in the ditches between mounds
B. Uplands
1) some of the world's earliest farming happened at high altitudes
2) early cultures used llamas and their corrals became nurseries for a food fit for humans to grow and eat
3) earliest known experiments in domesticating the potato
a) high-altitude varieties of potatoes have a hidden advantage since the concentration of poison in potatoes lowers the higher they are grown
4) different highland regions developed crops that grew well in their particular climate, soil and environment
a) Mesoamerican highlands grew maize, beans and squash
b) hardiest indigenous staples available in most of Eurasia and Africa are rye and barley
c) farmers in Ethiopia cultivated teff and switched to millet
C. Alluvial Plains
1) soil is made up of sediment and other organic matter, restores nutrients and compensates for lack of rain
2) people channel the floods of rivers to keep crops from being swept away
a) wheat and barley grew around Egypt's Nile, the lower Tigris and Euphrates rivers, and the Indus River
b) people first farmed millet on alluvial soils in a somewhat cooler, moister climate in China around the Yellow River
c) three crops of rice a year could grow on soil that the annual counterflow of the Mekong River created
d) rich wheat fields surrounded farming economies in Jericho on the river Jordan
