Sustainability
“Sustainability…meets the needs of the present generation
without compromising the ability of future generations
to meet their own needs”
United Nations. 1987. Report of the World Commission on Environment and Development, General
Assembly Resolution 42/187, 11 December 1987.

“…meet[ing] the needs of
the present generation…”
Landscaping Needs:
Aesthetics
Comfort
Emotional
Social
Financial
Food

Impact
How does my landscape affect the world?
Butterfly effect
Ex: Back to the Future
Ex: Weather

e x t e n s i o n . u s u . e d u
Impacts
Sensitive dependence on initial conditions
EX: How does misuse/overuse of chemicals affect our future?
Landscape is a mini-ecosystem that affects the
surrounding environments (landscapes) and thus the
surrounding ecosystems (world)

Plant Materials
Saving ideas:
Minimal water, fertilizers, pesticides, pruning, etc.
Savings in energy costs, i.e. cooling, wind break…
Location to reduce mowing and other difficulties
Long term vs. short term
Mulch area
Soil depth, improvement
Use low pest plants
