Deconstructing Nature and Society through Sustainability, Natural Resources, Land Use, and Theoretical Frameworks.
Enduring Understanding: PSO-1 Slide 1 of 6
Three Pillars of Geography
PSO-1.B.1
Sustainability
The use of Earth’s renewable and nonrenewable natural resources in ways that do not constrain resource use in the future.
Future-focused systems
Natural Resources
Substances provided by the environment that are useful to people, economically and technologically feasible to access, and socially acceptable to use.
Renewable vs Nonrenewable
Land Use
How humans modify and manage terrestrial surfaces for agricultural, industrial, residential, and recreational purposes.
Human footprint on space
How does human action reshape physical limitations? Slide 2 of 6
The Evolutionary Theories
PSO-1.B.2
Environmental Determinism
"Nature Commands"
The belief that the physical environment, especially climate, is the primary force shaping human culture and societal development. Historically used to justify ethnocentric hierarchies and colonial biases.
Suggests humans are passive products of climate.
Ignores technological agency and complex choices.
Possibilism
"Humans Adapt"
The theory that physical features impose restrictions, but human cultures have the agency, ingenuity, and technology to choose options from multiple environmental possibilities.
Champions cultural choices and modern engineering.
Recognizes limits while exploring extreme adaptations.
From deterministic constraints to adaptive alternatives. Slide 3 of 6
Real-World Case Studies I
Spatial Case Studies
Andes Mountains
Inca Agricultural Terracing
How did the Incas construct steep stone steps (andenes) to farm vertically, conserve water, and avoid crop frost in an incredibly cold and steep physical environment?
Key Dynamic: Adapting steep landscapes to maximize land use and manage limited resources sustainably.
Central Asia
Aral Sea Degradation
How did intense Soviet cotton irrigation projects bypass ecological limits, desiccating one of the world's largest inland bodies of water and turning it into a desert dustbowl?
Key Dynamic: Unsustainable water exploitation leading to complete ecological and economic collapse.
Analyze: Which elements represent sustainable adaptation versus environmental overreach? Slide 4 of 6
Real-World Case Studies II
Possibilism & Extreme Engineering
Netherlands & Singapore
Netherlands & Singapore Reclamation
In Singapore, hills were leveled to reclaim 130 km² of sea. In the Netherlands, massive dikes and polder systems drained sea inlets to construct liveable, low-lying farmable lands.
Key Dynamic: High-tech possibilism pushing back geographic boundaries to expand living and economic spaces.
Dubai & Sahel Region
Desert Frontiers
Dubai engineered artificial palm islands and air-conditioned microclimates. Across the Sahara, 21 African nations are planting the Great Green Wall to block advancing desertification.
Key Dynamic: Combatting and overriding desert limits through strategic engineering and botanical barriers.
How far can human engineering bend natural limitations? Slide 5 of 6

Topic 1.5: Environmental Determinism vs. Possibilism (PSO-1.B.2)
Name: ________________________
Date: __________ Period: _____
Learning Objective PSO-1.B: Theories regarding the interaction of the natural environment with human societies have evolved from environmental determinism (nature controls culture) to possibilism (humans adapt and choose).
Part A: Conceptual Mapping — The Theoretical Shift
Environmental Determinism
The theory that physical environment, climate, and geography strictly govern and dictate human behavior, cultural traits, and societal growth.
Identify 1 Core Criticism:
Possibilism
The theory that physical landscape limits choices, but human ingenuity, culture, and technological agency provide alternative paths for development.

1 Andes Agricultural Terraces
Topic 1.5: Sustainability
The Incas faced steep mountain slopes, low temperatures, and rapid water runoff. Instead of moving, they reshaped mountainsides with flat steps supported by stone walls. These terraces trap thermal energy during the day and regulate water during storms.
Core Concept: Ecological Adaptation
Primary Resource: Mountain Topography
Task: Draw the spatial cross-section of a stone-faced terrace step. Card 1/6
2 Aral Sea Basin Crisis
Topic 1.5: Natural Resources
To transform semi-arid Central Asian plains into lush cotton fields, engineers built over 30,000 km of water canals. By cutting off flow to the Aral Sea, the sea dried up completely, leaving behind rusted fishing vessels, salt crusts, and catastrophic toxic winds.
Core Concept: Environmental Bypass
Primary Resource: Fluvial Water System
Task: Map the cause-and-effect flow chart of agricultural diversion. Card 2/6
3 Netherlands Polder Dikes
Topic 1.5: Possibilism
Much of the Netherlands is below sea level. Using the famous slogan, "God made the earth, but the Dutch made the Netherlands," they built massive dikes to wall off sea inlets, then drained the seawater out using traditional windmills and modern diesel pumping.
Core Concept: Land Reclamation
Primary Resource: Coastal Wetlands
Task: Identify how climate change threatens the physical dikes of Holland. Card 3/6
