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.

Sekilas Tentang Arsitektur Lanskap

Kadang bingung kalo mau ngejelasin cuma dengan beberapa kata karena waktu yang singkat kalo ada orang yang nanya tentang jurusan yang lagi saya jalanin sekarang. Arsitektur lanskap? Hmm, kadang jawaban yang keluar dari mulut cuma seputar arsitektur pertamanan beserta sedikit penjelasan tentang perbedaannya sama teknik arsitektur atau arsitektur interior, jurusan yang sama-sama ada kata arsitektur di dalamnya.  Bener sih, ilmu Arsitektur Lanskap itu perkembangan lebih lanjut dari ilmu awalnya yaitu Arsitektur Pertamanan. Tapi yang banyak orang pikir; bikin taman? Nyusun-nyusun tanaman di depan halaman rumah? Lah, itu mah nggak usah susah susah belajar jadi Arsitek Lanskap, tukang kebun atau tukang bikin taman pinggir jalan juga bisa! Padahal sebenernya dunia arsitektur lanskap yang belum banyak orang tau ini nggak cuma se-sempit kelihatannya. Nah, berhubung besok pagi saya ujian mata kuliah Daskap alias Dasar-Dasar Arsitektur Lanskap dan baru aja selesai baca abis slide sesi u

#DaysInJapan: Totoro Forest

Totoro Forest is a conservation forest located in Sayama Hills, Tokyo, which is categorized as a deciduous broadleaf forest. It name, Totoro, was taken from the main character of the animated movie titled “My Neighbor Totoro” that aired at 1988 by Studio Ghibli. The location of scenes in this movie are actually inspired by actual places in this forest. Hayao Miyazaki, who is the director of that movie, is the owner of the foundation that manage this forest called National Trust of Totoro No Furusato (Totoro Hometown) or simply called Totoro Fund . From the animations he made, we can see that Hayao Miyazaki is very concerned in the environmental conservation issues. That’s why he made this foundation which is named after one of  his animation masterpiece.
