Landscape Architecture & Water Conservation


Landscape Architecture

Landscape architecture is the profession which applies artistic and scientific principles to the research, planning, design  and management of both natural and built environments. (The American  Society o fLandscape Architects (ASLA))

The scope of landscape works:
  • Landscape design
  • Site planning
  • Stormwater management
  • Environmental restoration
  • Parks and recreation planning
  • Visual resource  management
  • Green infrastructure planning and provision
  • And private estate and residence  landscape master planning and design
So,  Landscape Architecture is Your environment, designed.


What is the current water problem?

Uses of groundwater in the world:
  • Groundwater (GW) is rarely used before196o's
  • Changes in knowledges & technology -> Use of GW began to rise
  • Until 2010, number of GW taken: 1000 km cubic/year -> 67% for irrigation, 11% for industry 
BUT
  • Low rate of GW return (replenishment)
  • High number of GW extraction
  • Loss of GW

What can Landscape Architecture do for Water Conservation?


1. Terraces
  • Reduce the speed of runoff in steep area.
  • Reduces soil erosion.


2. Hedges 
  • Reduce the speed of the water and so reduce the damage related to mudslides.
  • Stabilize banks when they are planted next to a stream
  • Reduce water loss by evaporation

3. Permeable pavements
  • Reduce the saturation of hydrological networks and water runoff
  • Reduce soil sealing

4. Select plants suited to the climate and soil
  • Get a more durable  and less demanding garden,  including the needs of watering.

5. Catchment basins
  • Allow the accumulation of runoff water for a certain period.
  • Reduce the velocity of runoff which then slowly flows into the water course.
  • Promote the sedimentation of the soil particles carried by these sources of water.

6. Maintain  Forests
  • Trees keep the number of water in the soil
  • Allowing a percentage of the rain to reach the ground.
  • Alternative -> urban forests.
