Contour ploughing or contour farming is the farming practice of ploughing and/or planting across a slope following its elevation contour lines. These contour lines create a water break which reduces the formation of rills and gullies during times of heavy water run-off; which is a major cause of soil erosion. The water break also allows more time for the water to settle into the soil. In contour plowing, the ruts made by the plow run perpendicular rather than parallel to slopes, generally resulting in furrows that curve around the land and are level. This method is also known for preventing tillage erosion.

planting crops
Because the flood waters produce water for the farmers
We prevent desertification by planting trees that need less water to survive in desert areas, and by not cutting down trees.
water is used in industries in preparing many of the chemical substances and in agriculture it is used for planting crops and irrigation purposes and for providing water for photosynthesis in plants.
Easy. Fertile ground for planting crops, lots of water and sunshine
She traded cloth, Nile water, frruit from the Nile banks, crops, silt for planting, and slaves.
It helped with all of the planting and giving water to the dry area. They also made irrigation systems off of the Nile to bring water to crops.
Stream valleys are a great place to settle since it provides you with fresh water and fertile soil for planting crops.
Crops hold the soil together with their roots, therefor preventing soil erosion.
It sounds like you're referring to irrigation, where water is diverted by ditches and canals to make land more suitable for planting crops. Irrigation ditches can divert water from free-flowing rivers and streams or from reservoirs created by dams.
Planting sea grass, building water breaks, building retention walls, restricting traffic.
It helps to prevent soil erosion, allows for water to be absorbed by the soil and can even be used strategically to divert water to drier locations on farm land.
