Concepts

Sustainable Environments are areas in which the natural environment can sustain a society and economy with out using a appropriate range of resources.

Sustain healthy ecosystems to maintain goods and services for people and living species.

Loʻi Kalo• 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

Loʻi Kalo• 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

Preservation & Management

Involves water-systems, land, atmospheric climates, etc.

Making the cycle of production and disposal more sustainable by lessening the consumption of land area

Kawainui Marsh• Largest remaining

wetland in Hawaiʻi• Encompasses 830 acres

of land in Kailua, Oʻahu• Area of Cultural and

Archeological significance

• Habitat for native and endangered species

• Natural flood control• Provides recreational

and educational opportunities

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 land use decision-making that protects watersheds

New-age Sustainable Environments

Reusable Architecture

Green Farming, Agriculture, and Aquaculture

Biospheres

Native Species Out planting

Natural Area Preserves

Outdoor Educational Opportunities

Hydro plants

Palekai• “Breakwall”• Defense against high

seas• Protects a range of

inhabited areas• Creates a safe area for

many activities

Hydroelectricity• 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
