Chapter 5: Economics, Policy, and Sustainable Development Notes

Chapter 5: Economics, Policy, and Sustainable Development

Overview

  • This chapter explores the interaction between economics and environmental policy, emphasizing sustainability and ecosystem services.

    • Key areas of focus:

    • How economies exist within the environment and rely on ecosystem services.

    • Valuation of ecosystem services and full cost accounting.

    • Environmental policy and the role of science in policymaking.

    • Historical context of U.S. environmental policy and laws.

Case Study: Costa Rica Values Its Ecosystem Services

  • Pago por Servicios Ambientales (PSA): Initiated in the 1980s to regain forest cover.

    • Government paid farmers and ranchers to:

    • Preserve forest on their land.

    • Replant cleared areas.

    • Allow forests to regenerate.

    • Establish sustainable forestry systems.

    • Payments were competitive with profits from farming and ranching.

  • Recognition of Four Valuable Ecosystem Services Provided by Forests:

    • Cleansing of Water and Reduction of Erosion.

    • Biodiversity Richness.

    • Scenic Beauty: Attracts ecotourism.

    • Reduction of Greenhouse Gases and Carbon Sequestration: Involves pulling carbon dioxide from the atmosphere.

  • Funding Sources:

    • Beneficiaries included:

    • Irrigators.

    • Bottlers.

    • Municipal water suppliers.

    • Hydroelectric plant operators.

    • A 3.5% tax on fossil fuels was implemented.

  • Impact by 2015:

    • Over 20% of the country’s land was registered in the PSA program.

    • Critics voiced concerns about wasted payments and benefits skewed towards wealthier landowners.

    • Forest Cover Trends:

    • Decreased from 1940 to 1987.

    • Increased afterwards (from 17% in 1983 to 53% today).

  • Important Statistics:

    • 2 million tourists visit Costa Rica's natural parks annually.

    • Approximately half of the nation’s GDP is tied to tourism.

Economics and the Environment

  • Definition of Economy:

    • A social system converting resources into goods and services.

    • Goods: Material commodities;

    • Services: Work done for others.

  • Economics: Study of how individuals utilize scarce resources for demand goods and services.

  • Ecosystem Input/Output Interaction:

    • Economies receive resources from the environment, process them, and discharge waste back into it.

    • Traditional economics may neglect these ecosystem interactions.

  • Natural Resources vs. Ecological Services:

    • Natural resources: Freshwater, trees (timber), energy from various sources (sun, wind, water, fossil fuels).

    • Ecological services: Air/water purification, soil formation, climate regulation, pollination, waste recycling.

    • Natural Capital: Contributions provided by ecosystems for human well-being and quality of life.

Economic Theories

Supply and Demand Theory

  • Neoclassical Economics:

    • Describes conflict between buyers wanting low prices and sellers aiming for high prices.

    • Compromise emerges through supply (amount available at a price) and demand (amount people will buy).

    • Market Equilibrium: Achieved when supply equals demand.

  • Cost-Benefit Analysis:

    • A comparison of estimated costs vs. benefits of a proposed action.

    • The optimal choice yields the greatest benefits exceeding costs.

    • Challenges arise when costs and benefits are difficult to identify (e.g., ecological costs of deforestation).

Assumptions in Neoclassical Economics

  • Economic models assume:

    • Natural and human resources are infinite or easily replaceable.

    • Focus on internal costs linked to the economic exchange.

    • Ignoring long-term effects in favor of immediate benefits.

    • Economic growth is essential for societal stability.

  • Problems with Resource Assumptions:

    • Depletion of natural resources (e.g., fossil fuels).

    • Overexploitation of resources (e.g., forests, fish stocks).

    • Contamination of inexhaustible resources (e.g., water).

External Costs

  • Definition: Costs affecting third parties not involved in a transaction.

    • Example of Air Pollution: PM2.5 (particulate matter) levels greater than 10 micrograms/cubic meter are deemed unhealthy; linked to serious health issues.

Environmental Trade-offs in Economic Decisions

  • Trade-offs are present when components conflict or compete.

    • Resource use demands an understanding of both benefits and drawbacks.

    • Economic discussions often involve opportunity costs linked to pursuing societal or political aims.

Sustainability of Economic Growth

  • Environmental Economics: Aims for sustainability, addressing market failures and promoting equilibrium akin to natural systems.

  • Assigning Values to Ecosystem Services:

    • A study in 2014 estimated Earth's biosphere provides over $148 trillion in services (in 2017 dollars).

Environmental Policy

Overview

  • Definition: A formal set of plans and principles for problem-solving and decision-making.

    • Public policy encompasses laws, regulations, and practices from various governance levels.

    • Environmental policy centers around human interactions with the environment.

Elements of Effective Policy

  • Effective environmental policy integrates science, ethics, and economics.

  • Market capitalism creates disincentives to address environmental impacts due to short-term profit focus.

    • Market prices often fail to reflect environmental degradation costs, prompting governmental intervention.

Challenges

  • Environmental protection perceived as an economic burden.

  • Long-term environmental issues vs. short-term political/business interests.

  • Wealth allows certain entities to exert disproportionate political influence, impeding progress.

Historical Context of U.S. Environmental Policy

  • Initial policies prioritized development (18th-19th century):

    • Supported resource extraction and settlement in western regions.

    • General Land Ordinances (1785 and 1787): Allowed government management of lands seized from Native American tribes.

    • Focus on limitless resource perception led to unregulated land distribution.

  • Shift towards conservation occurred in the late 1800s:

    • Yellowstone (first national park) established in 1872.

    • Forest reserves initiated in 1891.

    • First wildlife refuge designated in 1903.

  • 20th Century Developments:

    • Industrialization led to economic benefits but increased pollution.

    • Rachel Carson's "Silent Spring" (1962) highlighted health impacts of chemicals.

    • Pollution events, such as the Cuyahoga River fires, raised public awareness.

Major Environmental Protection Laws (1963-1980)

  • Clean Water Act (1977): Regulates waste discharge, protects wildlife, and improves U.S. waterways.

  • CERCLA or Superfund (1980): Funds hazardous waste cleanup, originally costs borne by polluters; currently taxpayers contribute.

  • National Environmental Policy Act (NEPA) (1970): Requires Environmental Impact Statements (EIS) for major federal actions affecting the environment. Public comment is incorporated into the review process.

  • Environmental Protection Agency (EPA): Created to consolidate various environmental regulations, managing monitoring and standards enforcement.

Evolution of Policy Response

  • 1980s Developments: Amendments aimed to weaken previous environmental laws under economic burden pretenses.

  • State Regulations: SEQR mandates local agencies examine environmental, social, and economic impacts of proposed projects.

    • SEQR Determination Types:

    • Negative Declaration: No significant environmental impact.

    • Conditioned Negative Declaration: Potential impact manageable with enforceable conditions.

    • Positive Declaration: Environmental concerns warrant an EIS for in-depth analysis and public review.
