useful, valuable, rich, costly, fi

5. Concepts
S Sustainable Environments are areas in which the natural
environment can sustain a society and economy with out using
a appropriate range of resources.
S Sustain healthy ecosystems to maintain goods and services for
people and living species.

6. Loʻ Kalo
i
• System of irrigated terraces
• Way of wetland farming in
a controlled area
• Knowledge of (Mahi ʻai )
agriculture incorporated
with (Kuhikuhipuʻuone )
architecture and (Mahi iʻa )
aquaculture

7. LoʻiKalo
• Constructed with banks of
earth or rock near the
Kahawai (stream)
• Irrigated with stream water
through the ʻauwai(ditch)
into the uppermost terrace
gradually into the
lowermost terrace
• Water then discharged
back into the stream

8. Preservation & Management
S Involves water-systems, land, atmospheric climates, etc.
S Making the cycle of production and disposal more sustainable
by lessening the consumption of land area

9. Kawainui
Marsh
• Largest remaining wetland
in Hawaiʻ i
• Encompasses 830 acres of
land in Kailua, Oʻ ahu
• Area of Cultural and
Archeological significance
• Habitat for native and
endangered species
• Natural flood control
• Provides recreational and
educational opportunities

10. Hahai ka ua i
ka Ulu lāʻau
• “The Rain Follows the Forest”
• 10% of the priority watershed
forests are protected
• DLNR has made securing the
future of our water supply a
priority and created this action
plan to meet the following
goals:
• Remove or contain damaging
invasive weeds that threaten
priority areas; Monitor and control
other forest threats including
fires, predators, and plant
diseases
• Restore and plant native species
in priority and buffer areas
• Educate people about the
cultural, economic, and
environmental importance of
conserving native forests;
Promote consistent and informed

11. New-age Sustainable
Environments
S Reusable Architecture
S Green Farming, Agriculture, and Aquaculture
S Biospheres
S Native Species Out planting
S Natural Area Preserves
S Outdoor Educational Opportunities
S Hydro plants

12. Palekai
• “Breakwall”
• Defense against high seas
• Protects a range of
inhabited areas
• Creates a safe area for
many activities

13. Hydroelectricit
y
• Electricity generated by
hydropower
• Hawaii mainly uses Run-of-
the-river Hydroelectricity
• Stations with small or no
reservoir capacity
• Water coming from
upstream must be used for
generation at that moment
or allowed to bypass dam
• Cleaner and produces less
greenhouse gasses then
Power Plants that burn oils
