How to move towards sustainable environment in aspect of water resource…

- - - - The spread of a city and its suburbs over increasingly rural land.
- - - - more pedestrian walkways in designing public spaces
      - less parking space between shop lots
      - vegetations needed to be plant at a certain space
    - - reducing carbon footprint
- - - - agricultural waste
      - radioactive waste
      - industrial waste
  - - - increase soil fertility
      - decrease chances of soil erosion
      - better protection against natural disasters
    - - increase food security during drought season
      - Increase soil fertility
      - High quality crop can be produced
      - Help break up soilborne pest and disease life cycles
    - - Moldboard plow: Inverts the soil to bury residues, terminate cover crops and perennial sod, and kill weeds
      - Disk plow: Concave disks mounted in a gang cut residue and invert soil laterally, loosening soil and mixing residue into the soil
      - Chisel plow: Curved shanks with chisel points are dragged through the soil without inversion
    - - Reduce the risk of erosion
      - The biomass produced by cover crops is usually returned to the soil, enhancing organic matter levels
      - Fibrous-rooted cover crops can promote aggregation and stabilize the soil
