Permaculture Design Course: Day 3, Session 1: 08h00-10h00

The document provides an agenda for Day 3 of a permaculture design course. The day will cover climate, decision-making, and patterns. In the morning session, the instructor will give a climate primer covering climate physics, the three main climate zones, and California's unique climate. Decision-making will also be discussed. After lunch, a second climate session will cover patterns in climate and wind flows. Patterns in design principles will then be the topic.

LA Arboretum PDC: Day 3, Session 1


How to Kill Vampires
UV, Solar & Thermal Radiation

• Speed = Distance/Time

• Higher Frequency is More Energetic

• Peak Solar Radiation Emission is Green

• Eyes Evolved & Plants are Smart, Albedo

• Greenhouse Effect, Cold Desert Nights, Fireplace Slab

• Thermal Inertia: Diurnal Cycle & Seasonal Temperature Lag


Simplification: 3 Climate Zones
TROPICAL! Areas free of frost.

No month under 64F mean temperature (T). Includes the


SUBTROPICS, for which coolest months 32F < T < 64F.

TEMPERATE! Some summer, real winter.

Coldest months T < 32F, warmest T > 50F. Includes POLAR,


for which the warmest month T < 50F (or perpetual frost).

ARID! Areas where precipitation exceeds evaporation.

Mean annual rainfall <= 19.5 inches. Includes DESERT, for


which mean rainfall <= 10 inches.
Soil-Building & Infrastructure Hints
Tropical -- Cool it, Drain it!

Mulch! Coax soil to store nutrients in humus, plant herbaceous


perennials, multi-tier, cross-ventilate, light-colored, flexible, well-
anchored shelter against hurricane/floods, shelterbelt, vines.

Temperate -- Warm it!

Greenhouse! Air lock, compost or animal heat, house insulation


& aspect, wind/cold breaks, free-range forage systems &
grassland grazing techniques.

Arid -- Store moisture!

Mulch! Increase humus, limit fertilizer & hooved herbivores,


harvest water, use rock piles, depression beds & N-S ridges,
slope effect, grill, roof drip swale, cool air source, structure
orientation & shape, wind/heat breaks, design for flood.

3) State of the Planetary Ecosystem
1. Deforestation & Soil Loss/Degradation
2. Loss, Degradation of Coastal Wetlands
3. Loss of Plant & Animal Diversity*
4. Coral Reef Loss*
5. Water Pollution
6. Water Scarcity & Increasing Rainfall Variability*
7. Air Pollution & UV
8. Sea Ice Loss*
9. Land-based Glacier Loss*, Permafrost Melting*
10. Increasing Temperature Variability*

*due all or in part to increasing concentrations


of greenhouse gases in earth’s atmosphere
