Sustainable Development

By the end of this lesson, students will be able to (per CED LO IMP-7.A):

• Explain how sustainability principles relate to and impact industrialization and spatial development (per LO IMP-7.A).
• Identify the four categories of problems sustainable development policies attempt to remedy: natural-resource depletion, mass consumption, pollution, and climate change (per EK IMP-7.A.1).
• Define ecotourism and explain how it can protect environments while providing jobs for local populations (per EK IMP-7.A.2).
• Identify the United Nations Sustainable Development Goals and explain how small-scale finance and public transportation projects measure development progress (per EK IMP-7.A.3).
• Apply Skill 5.D: explain the degree to which sustainable development concepts effectively explain effects across various geographic scales.
• Evaluate honestly when sustainable development succeeds and when it fails to deliver on its promises.

EK IMP-7.A.1 establishes the scope of what sustainable development attempts to address. EKs 2 and 3 name two specific CED-listed mechanisms. Skill 5.D asks whether any of these tools actually work at the scale at which a problem occurs.

Skill 5.D: effectiveness across scales

Skill 5.D asks students to explain the degree to which a geographic concept effectively explains effects across scales — local, city, state, national, supranational, and global. A policy that works at one scale may fail at another. A problem defined at the global scale may require action at every scale to address. Evaluating this is the core cognitive work of Lesson 7.8.

EK IMP-7.A.1 names four categories of problems. These are not optional framing — the exam expects students to recognize all four.

Sustainable development is an umbrella term for policies addressing the four challenges. The phrase itself traces to the 1987 Brundtland Report (Our Common Future), which defined it as "meeting the needs of the present without compromising the ability of future generations to meet their own needs." Major international policy milestones:

• Kyoto Protocol (1997): first binding international climate treaty; committed industrialized countries to emissions reductions. The United States never ratified.
• Millennium Development Goals (2000-2015): precursor to the SDGs; eight goals focused on poverty, education, health.
• Paris Agreement (2015): nearly universal participation; each country submits Nationally Determined Contributions (NDCs) and updates them every five years. Target: hold warming "well below 2 degrees" and pursue 1.5 degrees.
• European Union Green Deal (2019): supranational commitment to carbon neutrality by 2050, with binding intermediate targets.
• United States Inflation Reduction Act (2022): the largest climate-investment law in United States history, channeling hundreds of billions of dollars into clean-energy tax credits.
• China dual-carbon pledge: announced 2020, committing to peak carbon emissions by 2030 and reach carbon neutrality by 2060.
• Renewable transitions: Denmark generates over 50 percent of its electricity from wind; Costa Rica regularly runs over 99 percent renewable electricity through the year; Uruguay, Iceland, and Norway also exceed 95 percent renewable electricity.

Case examples

• Costa Rica: about 30 percent of the country's land area is protected (national parks, reserves); roughly 2 million ecotourists arrive each year; ecotourism is the leading source of foreign exchange, eclipsing traditional agricultural exports.
• Galapagos Islands (Ecuador): strict visitor caps, licensed-guide requirement, and itinerary restrictions protect endemic species. Unique fee structure: visitors pay a park-entry fee that funds conservation directly.
• Botswana (Okavango Delta): deliberate high-end, low-volume model — fewer tourists paying more per night than Kenya-style mass safari tourism. Lower footprint per dollar of revenue.
• Belize: barrier-reef snorkeling and mangrove eco-tours generate revenue that subsidizes reef and mangrove protection. Both ecosystems provide coastal defense against hurricanes.
• Rwanda: gorilla trekking permits cost roughly 1,500 United States dollars each; a portion of revenue funds community projects and conservation. Mountain gorilla population has recovered from approximately 250 in the 1980s to over 1,000 today.

Tensions and limitations

Ecotourism is widely oversold. Common problems:

• Greenwashing: resorts market themselves as eco-friendly without meaningful practices.
• Crowding: popular destinations (Galapagos, Machu Picchu, Zion National Park) degrade from the very traffic ecotourism brings.
• Revenue leakage: foreign tour operators capture much of the revenue, leaving local communities with low-wage work.
• Housing displacement: successful ecotourism destinations drive up property values, pricing out original residents.
• Carbon footprint: the flights getting visitors there often dwarf any conservation benefit.

The United Nations adopted 17 Sustainable Development Goals in September 2015 as Agenda 2030, a successor to the Millennium Development Goals. Each SDG has specific targets and indicators that enable measurement. EK IMP-7.A.3 specifies that the goals help measure progress in development, naming small-scale finance and public transportation projects as examples.

CED-named examples: small-scale finance and public transportation

The CED specifically names small-scale finance and public transportation as examples of how the SDGs measure progress:

• Microlending (small-scale finance): covered in Lesson 7.4. Small loans — often 50 to 500 United States dollars — to entrepreneurs without collateral or credit history, frequently to women. Grameen Bank (Bangladesh) is the canonical example. Microlending fits SDG 1 (poverty), SDG 5 (gender equality), SDG 8 (decent work), and SDG 10 (reduced inequalities).
• Bus Rapid Transit (public transportation): covered in Lessons 6.7 and 6.8. BRT systems use dedicated bus lanes to deliver subway-like service at bus-line cost. Bogota's TransMilenio, Curitiba's network, and Guangzhou's BRT serve hundreds of thousands of riders daily while cutting urban emissions. BRT fits SDG 11 (sustainable cities) and SDG 13 (climate action).

Skill 5.D asks students to explain the degree to which a geographic concept effectively explains effects across scales. Sustainable development action happens at multiple scales simultaneously:

• Local scale: community solar cooperatives, urban gardens, bike-share programs, neighborhood recycling.
• City scale: BRT systems, greenbelts, building-energy codes, urban tree canopy targets.
• State/province scale: California's climate legislation and emissions-trading program, state-level renewable portfolio standards.
• National scale: Germany's Energiewende energy transition, the United States Inflation Reduction Act, China's dual-carbon pledge.
• Supranational scale: European Union Emissions Trading System (the world's largest carbon market), European Union Green Deal.
• Global scale: Paris Agreement, United Nations Sustainable Development Goals, Montreal Protocol (ozone).

Which scale fits which concept?

• Ecotourism is mostly a local-to-regional phenomenon. A single protected area, a single community cooperative.
• SDGs are framed globally but measured nationally — each country reports progress, and indicators aggregate upward.
• Climate policy must operate at every scale. A global agreement (Paris) requires national NDCs that depend on state, city, and local action to actually deliver emissions cuts.
• Natural-resource depletion varies by resource: groundwater aquifers are basin-scale; ocean fisheries are trans-national; a forest can be local.

Sustainable development projects are often oversold. A serious Skill 5.D analysis requires acknowledging failures alongside successes.

• Paris Agreement pledges fall short: current NDCs, if fully implemented, aggregate to approximately 2.5 degrees of warming — not the 1.5 degree pledge. Many countries are not on track to meet even their current pledges.
• SDG progress is uneven: SDG 2 (Zero Hunger) is actively regressing. The number of people facing hunger has risen since 2019 due to COVID-19, the war in Ukraine, and climate shocks. SDG 6 (Clean Water) is also off track.
• Ecotourism can backfire: successful destinations drive up local housing costs and displace residents. Flights to reach them generate significant emissions. Crowding degrades the ecosystems ecotourism was supposed to protect.
• Greenwashing is pervasive: companies and governments label ordinary activities as "green" or "sustainable" to capture marketing benefit without changing practices. Careful students distinguish substance from label.
• Who pays? Wealthy countries produce most historic emissions but lower-income countries bear disproportionate climate impacts. International climate finance has consistently fallen short of pledges.

Four contrasting sustainable-development stories, each illustrating different CED concepts.

Costa Rica · Ecotourism + Renewables

~30% land protected; 99% renewable electricity

Costa Rica abolished its military in 1948 and redirected spending toward education, health, and conservation. Today roughly 30 percent of land is formally protected; approximately 2 million ecotourists arrive each year; and the electricity grid runs close to 99 percent renewable (hydro, geothermal, wind, solar) for most of each calendar year. A leading global example of aligning economic development with conservation.

Denmark · Wind Energy + Cooperative Democracy

Over 50% electricity from wind

Denmark generates more than half of its electricity from wind, the highest share among significant economies. Much of the wind capacity is community-owned through cooperatives — a model of "energy democracy" in which benefits flow to local residents rather than distant utilities. Industrial policy choices dating to the 1970s oil crisis produced a domestic wind-turbine industry (Vestas, Siemens Gamesa) that is a major export.

Rwanda · Community-Based Conservation

Mountain gorillas: ~250 (1980s) → 1,000+ today

Rwanda's gorilla-trekking permits (around 1,500 United States dollars each) generate substantial tourism revenue, a share of which funds community-development projects around Volcanoes National Park. Community members have a direct financial stake in gorilla conservation. The mountain gorilla population has recovered from fewer than 250 in the 1980s to more than 1,000 today — one of the clearest ecotourism success stories.

Norway · Oil Wealth, Electric Cars

EV market share: over 80% of new cars

A paradox: Norway is a major oil and gas exporter, yet it invests the proceeds through a sovereign-wealth fund (over 1.5 trillion United States dollars) that funds domestic public services. Meanwhile domestic policy has produced the world's fastest electric-vehicle adoption, with EVs exceeding 80 percent of new-car sales. Critics note that Norway exports the emissions it declines to burn at home.

1. EK IMP-7.A.1 names four problems sustainable development attempts to address. Apply Skill 5.D: at which scale does each problem most clearly appear, and at which scale(s) must action occur? Which of the four is most scale-spanning?
2. Ecotourism (EK IMP-7.A.2) promises both environmental protection and local jobs. Identify a specific ecotourism destination and evaluate the degree to which it delivers on each promise. What evidence would change your assessment?
3. The CED names "small-scale finance and public transportation projects" (EK IMP-7.A.3) as examples of how the SDGs measure progress. Why would the CED highlight these two rather than, say, renewable energy or reforestation? What do they share?
4. The Paris Agreement operates at the global scale but depends on national NDCs that depend on state, city, and local action. At which scale do you think climate policy most often fails? Defend with an example.
5. Consider Norway: a major oil exporter that runs on hydroelectricity and leads in electric-vehicle adoption. Is Norway a sustainable-development success or a hypocrisy? Apply Skill 5.D — the answer may depend on which scale you adopt.
