The document discusses sustainable environments and water resources in Hawaii. It provides information on global and local water distribution and types. It describes traditional lo'i kalo (taro patch) systems and their role in sustainable water management. Current challenges and strategies around watershed protection, invasive species removal, and reforestation are mentioned. New approaches to sustainable architecture, agriculture, hydroelectric power, and environmental education are also summarized.

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
