Sustainability Flashcards
What are the three pillars of sustainabilty?
Economic viability.
Social equity.
Environmental protection.
What are the negative impacts of horticultural practices?
use of fossil fuels in powered equipment, transport and the heating of
glasshouses
§ impact of monocultures on biodiversity
§ Biosecurity
§ importation of pests and diseases
§ soil degradation
§ leachate release
§ peat, pesticide, water, and plastic usage
How to prevent pollution in your garden?
Go Chemical Free (IPM)
Physical, biological, chemical
Use plants to tackle pollution - use hedges, not fences; indoor houseplants, remove concrete
PLastic free garden
Soil care
Water usage
Right plant right place
How to prevent use of fossil fuels?
Source equip/plants from local suppliers.
Use electrical or battery operated equip.
Reduce the frequency of tool or transport use.
Improve glasshouse insulation.
Grow plants in glasshouses that require less heating.
Impact of monocultures in gardens?
No biodiversity.
Provides less nectar/pollen and habitats.
Biosecurity?
Importing pests and diseases.
Buy local as it already grows here and may not bring in new pests.
How does hort contribute to 3 pillars of sustainability?
- ECONOMIC: Britain provides garden tourism from around the world; hort workers; hotels; restaurants; gift shops
- SOCIAL EQUITY:
Gardens for all; especially in low income neighborhoods. Green therapy and pride in neighborhood reduces crime. - ENVIRONMENTAL PROTECTION: Providing corridors and habitat for wildlife.
What is net positive for hort?
Benefitting wider environment.
new way of doing business;
Business puts back into society more than it takes out.
Puts more back into global economy.
Puts more back into environment than it takes out.
Give an example of net positive hort
TREE PLANTING:
Production, transport, stakes and guards have negative impact.
Benefits of newly planted woodland on society: green space, wellness and wildlife can offset this negative.
Ex; purchase of land, trees= economic benefit (employment)
Woodlands sequester carbon while supporting wildlife.
What are positive impacts of hort?
carbon sequestration
water retention
soil retention
habitat for wildlife
Negative impacts of hort?
transportation
heating of structures
packaging of produce
fertilizer production
extraction of peat
manufacturing of products.
Water usage.
How does Hort mitigate climate change with water usage?
Rain barrels (water butts)
Slowing rainwater
Reduces flooding w/plants
Provides shade
Rain gardens
Retains soil moisture
Water is the bloodstream of the biosphere. But we are profoundly changing the water cycle. This is now affecting the health of the entire planet.
Impact of Climate Change on Hort
Plant resilience to drought.
Plant resilience to rainfall and flooding.
Plant resilience to wind and extreme weather.
reduced vernalization period. (amount of cold temps to germinate and flower)
Impact of Climate Change on gardens?
Plant establishment:
Spring droughts -planting window?
High temps stress
Impacts of drought.
Garden maintenance:
New and novel plant health risks.
Longer growing seasons
Effect on pollinators (phenology - cycles of plants)
pollarding of trees and other stormscape concepts.
Developing rain gardens
People based factors:
High UV conditions
Extreme heat
Extreme weather events
