Applying the Geographic Lens

Overview

The geographic lens reads events as constrained by the unchangeable: terrain, distance, climate, the locations of resources and people. Geography is not destiny, but it sets the cost structure within which everything else happens. The analyst's job is to make the spatial structure visible when other framings have abstracted from it.

Core principle: Distance, terrain, and chokepoints impose costs no policy can wish away — but they can be technologically circumvented at known cost. Read every event as embedded in a specific physical structure.

When to Use

• Maritime/aviation incidents, blockades, freedom-of-navigation operations.
• Pipeline, cable, port, rail, or canal disruptions and projects.
• Resource access (oil, gas, minerals, water, food).
• Border, territorial, or maritime-claims disputes.
• Climate-related stories (droughts, floods, heat) connecting to migration, conflict, or production.
• "Why is X strategic" questions about specific locations.

The Frameworks

Classical geopolitics

Use these as orienting devices, not deterministic theories — they encode real spatial logics but were built for specific eras.

• Mackinder's Heartland thesis — control of inner Eurasia confers continental power; sea powers must prevent its consolidation. Frames Russia/Central Asia/China continental dynamics.
• Spykman's Rimland — the coastal arc (Europe-Mideast-South/SE Asia) is where power is contested; whoever controls the rimland controls Eurasia. Frames US alliance system.
• Mahan's Sea Power — control of sea lines of communication (SLOCs) and key ports/bases is decisive. Frames naval doctrine and basing policy.
• Cohen's shatterbelts — regions of overlap between great-power systems where conflict concentrates. Currently: Eastern Europe, Middle East, parts of South China Sea periphery.

Choke points

The world's commerce passes through a small number of narrow points; disruption at any of them has outsized effects.

• Maritime chokes: Strait of Hormuz (~20% of global oil), Bab el-Mandeb / Red Sea / Suez (Europe-Asia trade), Strait of Malacca (East Asia energy and trade), Bosphorus & Dardanelles (Black Sea), Panama Canal, Cape of Good Hope (Suez bypass), Danish Straits.
• Land: Khyber Pass, Wakhan, Brenner, Khorgos, Tatar Strait railroads.
• Energy infrastructure: Druzhba pipeline, TurkStream, Nord Stream, Baltic Pipe, Trans-Anatolian, Caspian export routes; LNG terminal locations.
• Cables: ~99% of intercontinental data on undersea cables; landing stations (Marseille, Fortaleza, Singapore, Mumbai, Egypt, etc.) are the real chokepoints.

For any chokepoint, ask: what's the alternative routing, at what cost, with what time-to-implement? Cape routing adds ~10 days and 25–30% to a Suez-Asia voyage; pipeline alternatives are years to build.

Economic geography

• Distance decay — interaction (trade, communication, conflict probability) decays with distance. The gravity model formalises this; the literature places the elasticity around −1 even in the digital era.
• Krugman's economic geography — increasing returns + transport costs → agglomeration → core-periphery patterns. Once concentration starts, it self-reinforces. Explains why deconcentration is hard despite policy.
• Resource geography — concentration matters more than reserves. Lithium (Chile, Australia, China processing), cobalt (DRC), rare earths (China processing), gas (Russia, Iran, Qatar, US), wheat (Russia, US, EU, Ukraine, India). Concentration creates leverage and diversion incentives.
• Water — transboundary rivers (Nile, Tigris-Euphrates, Mekong, Indus, Brahmaputra) where upstream control over flow creates long-term leverage. Aquifers (Ogallala, Indo-Gangetic) where depletion is regional security.

Climate & physical environment

• Climate-conflict link — real but mediated. Climate stress aggravates conflict where institutions are weak; does not cause conflict alone (Buhaug, Hsiang, Burke debates). Do not overclaim.
• Sea-level rise, coastal storms — affect specific regions disproportionately; migration effects concentrated near coastal lowlands and small island states.
• Heat and productivity — measurable effects on agricultural yields, labour productivity, infrastructure stress.
• Polar geography — Arctic opening (Northern Sea Route, Northwest Passage) creates new chokes and basing questions.

Infrastructure as geopolitics

• Belt and Road, Build Back Better, Global Gateway, EU Global Gateway — infrastructure funding programmes are about both economics and strategic positioning. Map specific projects: ports (especially dual-use), rail corridors, pipelines, fibre, power generation. Each creates dependencies.
• Port classification — bulk, container, energy, military-suitable. Dual-use potential determines strategic value beyond commerce.
• Logistics hubs — Dubai/Jebel Ali, Singapore, Rotterdam, Shanghai, Panama, Djibouti — where the world's commerce concentrates and so does intelligence and political leverage.

Quick Reference

Question	Look at
Trade-route exposure?	Container/oil/gas flow data, alternative routing cost and time
Resource leverage?	HHI on supply concentration, processing concentration, substitutability
Pipeline politics?	Owner/operator, transit countries, takeoff points, contractual obligations
Naval significance?	Distance to bases, SLOC dependency, basing rights along route
Cable / data risk?	Landing-station locations, cable routes, peering at IXPs
Border-dispute structure?	Topography, ethnic distribution, resource location, infrastructure
Climate-driven risk?	Long-run climate projection, agricultural exposure, water stress, coastal exposure

Common Mistakes

Mistake	Fix
Geographic determinism	Geography sets cost structure; institutions and tech still drive outcomes
Treating chokepoints as cliff edges	Most disruptions have alternatives at known cost; quantify the cost
Ignoring chokepoint substitution	Pipelines, rail, alternate routes redistribute over time
Applying Mahan/Mackinder without translating	Original works were of their era; technology has changed the cost surface
Confusing reserves with production	Reserves measure geology; production and processing concentration measure leverage
Treating climate-conflict as direct	The link is mediated by institutions; don't skip the mediator
Using outdated maps of infrastructure	New rail corridors, LNG terminals, cables redraw the picture rapidly
One-mode thinking	Trade flows shift between modes (sea/rail/air/pipeline) — don't track only one

Worked Example

Headline: "Houthi attacks force shipping to reroute around Cape; Asia-Europe rates spike" — through the lens:

• Chokepoint affected: Bab el-Mandeb / Red Sea / Suez complex. Normally ~12% of global trade by value, ~30% of container traffic Asia-Europe.
• Alternative routing: Cape of Good Hope. Adds ~10 days, 25–30% fuel cost, additional vessels needed to maintain schedules. Effect on supply: implicit ~10% reduction in effective container capacity for the affected lane.
• Distribution of effects: Asia-Europe most exposed; Asia-Americas (Pacific) almost unaffected; intra-Asia largely unaffected; Mediterranean ports lose throughput. The geographic distribution of pain shapes who lobbies for what response.
• Time horizon: Insurance pricing reacts in weeks; vessel-deployment shifts in months; route fundamentals (e.g., trans-Eurasian rail capacity) over years.
• Adjacent chokes: Hormuz tension would compound; Panama drought (lower Gatun levels) would force more vessels to choose between the bad options.
• Indicators to watch: Drewry / Xeneta container rates by lane; AIS aggregate traffic counts at Bab el-Mandeb (MarineTraffic, Suez Canal Authority statistics); insurance war-risk premia; LNG/oil tanker behaviour distinct from container behaviour (different risk tolerance and contracts).
