Study Notes: The Tragedy of the Commons, Public Lands, and Resource Use

The Tragedy of the Commons; Public Lands, and Resource Use

• Big Picture: Land is used for many things (food, homes, resources, fun, animal homes, energy). Public lands belong to everyone, not private owners. Deciding who uses land and how involves rules, laws, and disagreements.

Public Lands: Who Owns & Controls Them?

• Public lands are managed by local or federal governments for regular citizens; they aren't private.

• Historically, the government let companies use public land for timber, mining, oil, or grazing through leases.

• Example 1 (Protest): Tim DeChristopher protested an oil lease auction in 2008 by bidding without paying. He argued it was civil disobedience against harmful land use. He went to prison.

• Example 2 (Lawsuit): In 2016, Terry Tempest and Brooke Williams tried to lease land for solar/wind energy, not oil. The government denied them, leading to a lawsuit that was rejected.

• Animal Conflicts: Ranchers grazing cattle on public lands sometimes face wolves killing livestock. Agencies have killed wolves, sparking legal debates over wildlife management.

• Water Fights: Drought and climate change led to restricted water use from Lake Mead (Colorado River) in 2021, affecting states and Mexico, causing ongoing legal battles.

• Core Questions: Who is responsible when land is held for everyone? Can governments save land for nature only? Do cities get water rights even if it harms others?

• Goal: We need to look at land fights using science and sustainability to ensure land use minimizes harm and lasts long-term.

Simple Key Ideas

• Tragedy of the Commons: When a shared resource gets used up because individuals act selfishly, not thinking of the group.

• Externalities: Costs or benefits of a product/service not shown in its price.

  • Negative Externality: Harms others (e.g., pollution).

  • Positive Externality: Benefits others (e.g., nice views).

• Internalizing Externalities: Making sure these hidden costs/benefits are included in prices or rules (e.g., pollution fees).

• Ostrom's Discovery: Communities can manage shared resources well on their own; it's not just about private ownership or government rules.

Land & Water Use: The Environmental Story

• US Public Land Managers (about 95% of federal lands):

  • Bureau of Land Management (BLM): Grazing, mining, timber, recreation.

  • U.S. Forest Service (USFS): Timber, grazing, recreation.

  • National Park Service (NPS): Recreation and saving nature.

  • Fish and Wildlife Service (FWS): Protecting wildlife, hunting, recreation.

• Key Laws for Land Use:

  • National Environmental Policy Act (NEPA, 1969): Requires environmental checks for federal projects; lets the public comment.

  • Endangered Species Act (ESA, 1973): Protects species in danger and their homes; guides decisions in their presence.

• Public lands try to balance many uses (grazing, mining, timber, fun) with saving nature.

• Aldo Leopold: Believed we have a moral duty to protect land; his ideas inspire modern sustainability efforts.

The Tragedy of the Commons: Deeper Dive

• Definition: Shared resources get overused because individuals don't pay the full cost of their actions, leading to ruin for everyone.

• History: First described by Lloyd (1833) with village pastures; popularized by Hardin (1968) in environmental science.

• Village Pasture Example: Everyone adds more animals to a shared field because it benefits them. But too many animals destroy the field for all.

• Externalities Review:

  • Negative: Overusing shared land hurts everyone (e.g., soil washing away).

  • Positive: Well-kept land offers benefits like beauty or clean air.

• Solving Externalities: Can involve charging fees, permits, or changing ownership so that private actions reflect true costs/benefits.

• Solutions: Government rules, private ownership, and importantly, community-led management (Ostrom) can prevent this tragedy.

• Public lands often have different rules for different uses (protection, resource use, fun).

Protected Lands: The Numbers

• Global Protected Areas (UN Data):

  • 2004: $18{,}800{,}000 ext{ km}^2$ protected worldwide (which is $1.88 imes 10^{9}$ ha).

  • 2014: Protected area was about $3.2 imes 10^{9}$ ha. (Around 14% of land, 3.4% of oceans).

  • Change (2004-2014): Increased by $1.32 imes 10^{9}$ ha, or roughly 70.2% growth.

• Most Recent Data (2018): $46{,}414{,}431 ext{ km}^2$ protected, equal to $4.6414431 imes 10^{9}$ ha.

• US Protected Lands (Example):

  • About 42% of US land is public; 25% is federal.

  • Four agencies manage about 95% of federal lands.

  • Total US land area $\approx 9.49 imes 10^{8}$ ha.

  • Protected land (2020) $\approx 1.24 imes 10^{9}$ ha (This number likely includes overlap or different definitions, but shows a big portion of land is protected, around 13% by some counts).

• Key Trend: Protected areas are growing globally, but how effective they are is still debated.

Forests, Rangelands, and How We Manage Land

• Rangelands: Dry, open grassy areas mostly for grazing cattle. They can suffer from overuse, fires, and loss of species.

• Forests: Areas covered by trees. Two main ways to cut trees:

  • Clear-cutting: Cutting down almost all trees in an area.

  • Bad points: Causes soil to wash away, dirties streams, makes rivers hotter (hurting fish), releases carbon from soil, destroys habitats, increases flood risk, and reduces biodiversity. Often replanted with just one type of tree, creating weaker forests.

  • Good points (sometimes): Can be quick, good for fast-growing trees, and creates open areas for certain animals temporarily.

  • Selective Cutting: Cutting only a few trees at a time.

  • Good points: Keeps most of the forest structure and biodiversity, good for trees that like shade, and can provide timber for a longer time. Less damage than clear-cutting.

  • Bad points: Still needs roads (which break up habitats), can remove the most valuable trees, and might cost more.

• Ecologically Sustainable Forestry: Tries to cut trees while keeping the forest healthy, protecting non-commercial species, and maintaining nature's balance. Might use less machinery (like horses for logging) but can be more expensive.

• Tree Plantations vs. Natural Forests: Plantations are usually rows of one type of fast-growing tree. They can use up soil nutrients and don't have the rich variety of plants and animals found in natural, old-growth forests.

• Biodiversity & At-Risk Species: For example, the marbled murrelet (a bird) needs old redwood forests. More logging means fewer homes for them.

• Ethics & Policy: Guided by Leopold's idea of respecting land; laws like NEPA and ESA help balance development with protecting nature.

Environmental Problems from Harvesting Trees

• Clear-cutting's Damage:

  • Soil washes away, streams get muddy and hotter (less oxygen for fish).

  • Animals lose homes, biodiversity drops.

  • Increased flood risk (less water soaks into the ground).

  • Soil loses organic stuff as it gets hotter and microbes work faster.

  • New forests after clear-cutting are often just one type of tree, making them easily damaged by pests and climate change, and not as diverse.

  • Preparation for replanting might involve fires or chemicals, further harming soil and water.

• Biodiversity: While some argue clear-cutting can create new diverse spots in vast forests, it generally harms the complex habitats many species need.

• Economics: Clear-cutting is cheap and fast, but it often ignores the huge costs to nature (like losing clean water or a stable climate). Policies need to balance money with nature's value.

Selective Cutting & Sustainable Forestry: The Good and Bad

• Selective Cutting Benefits:

  • Keeps forest structure and many types of life.

  • Allows for long-term timber harvesting.

  • Less habitat damage compared to clear-cutting.

• Selective Cutting Drawbacks:

  • Still requires roads and machinery, fragmenting habitats.

  • Might remove the best trees, impacting forest genetics.

  • Can yield less timber over time and potentially cost more.

• Ecologically Sustainable Forestry Aims:

  • Provide wood while keeping nature healthy and diverse.

  • Some methods try to use less fossil fuel (e.g., logging with horses) to reduce environmental footprint, though this can be expensive.

How Rules, Actions, and People Work Together

• Public participation (through NEPA) is vital; comments can improve projects.

• ESA requires changes to projects if endangered species are present to protect them.

• Land-use debates always involve balancing getting resources (energy, timber) with protecting nature and ensuring fairness for local communities and the environment in the long run.

Do the Math: Understanding the Numbers

• Protected Land Growth:

  • 2004: $1.88 imes 10^{9}$ ha protected.

  • 2014: $3.20 imes 10^{9}$ ha protected.

  • Change: Increased by $1.32 imes 10^{9}$ ha, a $70.2\%$ increase from 2004 to 2014.

• UN 2018 Data: $4.6414431 imes 10^{9}$ ha are protected globally.

• US Data (Examples):

  • Total US land: $\approx 9.49 imes 10^{8}$ ha.

  • Protected US land (2020): $\approx 1.24 imes 10^{9}$ ha (This means a significant portion of US land is protected, around 13%).

  • About 42% of US land is public, 25% federally owned, mostly by 4 agencies.

Why This Matters in Real Life

• The Tragedy of the Commons affects many things: air, water, soil, fish, forests. Without rules, we can use them up.

• Externalities show why markets alone can't manage resources well. Tools like fees, permits, and quotas help make sure costs are shared fairly.

• Ostrom's research proves that local communities can successfully manage shared resources if they have clear rules and work together.

• Good policy must balance nature, money, and fairness. Laws like NEPA and ESA, and smart forestry, are key.

Quick Reference: Main Ideas

• Tragedy of the Commons: Overusing shared resources because no one owns or regulates them, leading to damage.

• Externality: A cost or benefit not included in the price; can be bad or good.

• Internalizing externalities: Adding these hidden costs/benefits into economic decisions (e.g., pollution fees).

• Ostrom: Person who showed communities can manage shared resources well.

• NEPA: Law requiring environmental reviews for federal projects.

• ESA: Law protecting endangered species and their homes.

• BLM/USFS/NPS/FWS: Main US federal land management groups.

• Leopold: Thought we have a moral duty to protect land.

• Clear-cutting: Cutting almost all trees; fast but causes lots of environmental harm.

• Selective cutting: Cutting fewer trees; better for the environment, keeps forest structure.

• Ecologically sustainable forestry: Focuses on keeping forests healthy long-term while also producing timber.

• Reforestation: Replanting trees; can create single-species farms, which affects biodiversity.

• Land use categories: Different ways we use land, like grazing, mining, timber, recreation, or conservation.

Practice Questions (Things to Think About)

• How do laws like NEPA and ESA change what happens on public lands?

• What are the good and bad points of clear-cutting versus selective cutting for the environment and money?

• If a negative externality (like pollution) was included in the cost of using a shared pasture, how might land-use decisions change?

• How does Ostrom's work suggest that communities, not just governments or private owners, can prevent resource overuse?

• Use the "Do the Math" data to explain how much protected land grew from 2004 to 2014 and what that means for global efforts to save nature.

• Why do different groups (ranchers, environmentalists, local people) care about land use on public lands, and how do their views affect decisions?

• What happens when a project needs to be built where an endangered species lives, according to NEPA and ESA?

Summary Takeaways

• Shared lands need rules to stop overuse. Without them, it's the tragedy of the commons.

• Externalities are key to resource management; we need ways (private ownership, permits, fees, community rules) to account for these hidden costs/benefits.

• Managing forests involves balancing money, biodiversity, and healthy ecosystems. Sustainable methods aim for long-term balance.

• Laws (NEPA, ESA) and government agencies control how land and water are used and protected, leading to ongoing debates about fairness and effectiveness.

Here are the answers to your practice questions, based on the provided notes:

1. How do laws like NEPA and ESA change what happens on public lands?

   • NEPA (National Environmental Policy Act): Requires federal projects to conduct environmental checks and allows the public to comment on these projects, ensuring transparency and considering environmental impacts before approval.

   • ESA (Endangered Species Act): Protects species in danger and their habitats. This means any project on public lands must guide decisions (and often make changes) in the presence of endangered species to ensure their survival and habitat protection.

2. What are the good and bad points of clear-cutting versus selective cutting for the environment and money?

   • Clear-cutting:

     • Good points (money): Quick and cheap for harvesting timber, good for fast-growing trees, can temporarily create open areas for some animals.

     • Bad points (environment): Causes soil erosion, muddies and heats streams (harming fish), releases carbon from soil, destroys habitats, increases flood risk, reduces biodiversity, and often leads to replanting with single-species trees that are less diverse and more vulnerable.

   • Selective cutting:

     • Good points (environment): Keeps most of the forest structure and biodiversity, good for shade-loving trees, and allows for long-term timber harvesting and less habitat damage.

     • Bad points (money/environment): Still requires roads (fragmenting habitats), might remove the most valuable trees, can yield less timber over time, and might cost more.

3. If a negative externality (like pollution) was included in the cost of using a shared pasture, how might land-use decisions change?
   If a negative externality like pollution (e.g., from overgrazing leading to soil erosion or water contamination) was included in the cost, users would have to pay for the damage they cause. This would make overusing the pasture more expensive, incentivizing individuals to graze fewer animals, adopt more sustainable practices, or seek alternative land uses. This helps ensure that private actions reflect the true costs to the environment and community, thus reducing overuse and preventing the "tragedy of the commons."

4. How does Ostrom's work suggest that communities, not just governments or private owners, can prevent resource overuse?
   Elinor Ostrom's research showed that local communities can successfully manage shared resources on their own without needing top-down government rules or private ownership. Her work highlights that if communities develop clear rules, monitoring systems, and ways to enforce decisions, they can prevent the overuse of shared resources like pastures or fisheries by working together and holding each other accountable.

5. Use the "Do the Math" data to explain how much protected land grew from 2004 to 2014 and what that means for global efforts to save nature.

   • Growth: From 2004 to 2014, global protected land increased from $1.88 \times 10^{9}$ ha to $3.20 \times 10^{9}$ ha. This represents an increase of $1.32 \times 10^{9}$ ha, or approximately a $70.2\%$ growth during that decade.

   • Meaning for global efforts: This significant increase shows a strong global trend towards conserving natural areas, indicating a growing recognition and commitment to protecting biodiversity, ecosystems, and natural resources worldwide. While the effectiveness of these protections is debated, the sheer expansion in area signifies a major international effort to curb environmental degradation.

6. Why do different groups (ranchers, environmentalists, local people) care about land use on public lands, and how do their views affect decisions?

   • Ranchers: Care about public lands for grazing their livestock, viewing them as a resource for their livelihoods. Their demand for grazing rights can conflict with conservation efforts.

   • Environmentalists: Advocate for protecting public lands for conservation, wildlife habitat, and recreation. They often push for stricter regulations on resource extraction to preserve ecosystems.

   • Local people: May have mixed views, caring about access to resources (like water or timber), recreational opportunities, or the preservation of local natural beauty and cultural heritage. Their input can influence decisions through public participation processes.

   • Effect on decisions: These differing views lead to ongoing debates and legal battles over land use (e.g., animal conflicts, water fights). Decisions on public lands often involve balancing multiple, sometimes conflicting, uses (grazing, mining, timber, recreation, conservation) through laws like NEPA and ESA, aiming for fairness and long-term sustainability.

7. What happens when a project needs to be built where an endangered species lives, according to NEPA and ESA?
   According to NEPA and ESA:

   • NEPA would require an environmental check (e.g., an Environmental Impact Statement) for the federal project, evaluating its potential effects on the endangered species and its habitat. The public would have an opportunity to comment.

   • ESA would then specifically mandate protections for the endangered species and its home. This means the project would likely need to be modified, relocated, or even stopped if it poses a significant threat to the species' survival. The decisions would be guided by the need to protect the species.
