Study Notes

The Concept of Sustainable Development

Sustainable development attempts to balance economic development with environmental protection and social equity
Early criticisms of traditional growth models questioned their environmental and social impacts
The Brundtland Report (1987) established a global framework for sustainable development, defining it as "meeting the needs of the present without compromising the ability of future generations to meet their own needs"
The three pillars of sustainable development are:
- Economic Development: focuses on growth, employment, and improving living standards.
- Social Equity: aims for fairness, justice, and inclusivity, addressing issues like poverty and inequality.
- Environmental Protection: emphasizes preserving natural resources, biodiversity, and ecosystems.
Global summits, such as Rio+20 (2012), aim to advance sustainable development through international cooperation and policy initiatives.

Weak vs. Strong Sustainability Debate

Weak Sustainability:
- Relies on the principle of substitutability, suggesting that human-made capital can replace natural capital
- Advocates for technological advancements to offset environmental damage
Strong Sustainability:
- Emphasizes the irreplaceability of natural capital, especially critical resources like biodiversity and ecosystem services
- Argues that exceeding planetary boundaries leads to irreversible damage
- Advocates for conservation and resource management to maintain long-term ecological health

Climate Change and Policy Responses

Human activities, primarily fossil fuel combustion, contribute to climate change through greenhouse gas emissions, altering the Earth's energy balance
The Intergovernmental Panel on Climate Change (IPCC) provides scientific assessments of climate change, including projections of future warming and associated risks
Policy responses to climate change aim to mitigate emissions (reduce greenhouse gas releases) and adapt to the impacts of climate change (build resilience to its effects)
Examples of mitigation strategies include:
- Emissions trading systems: Market-based mechanisms that put a price on carbon emissions
- Renewable energy initiatives: Transitioning from fossil fuels to renewable energy sources like solar and wind power.

Sustainable Development Models and Criticism

Traditional Western development models have been criticised for:
- Focusing on material wealth and economic growth at the expense of social and environmental well-being
- Often leading to environmental degradation, resource depletion, and social inequalities
The Brundtland Report's definition of sustainable development addresses these concerns by:
- Prioritizing intergenerational equity, ensuring that future generations inherit a healthy planet
- Recognizing the interconnectedness of economic, social, and environmental systems
Examples influenced by sustainable development include:
- International agreements like the Paris Agreement, aiming to limit global warming
- Sustainable Development Goals (SDGs), a set of 17 goals adopted by the United Nations to achieve a more sustainable future.

Ecosystem Services and Human Well-Being

Ecosystem services are the benefits that humans derive from nature, including:
- Provisioning services: Food, fresh water, timber, and fiber
- Regulating services: Climate regulation, flood control, water purification
- Supporting services: Nutrient cycling, soil formation, pollination
- Cultural services: Recreation, aesthetic beauty, spiritual values
Ecosystem services are crucial for human well-being, impacting health, livelihoods, and quality of life
Challenges in valuing ecosystem services include:
- Monetizing non-economic values: Difficulty assigning monetary value to intangible benefits like aesthetic beauty or spiritual significance
- Ecological complexity and uncertainties: Ecosystems are dynamic and interconnected, making it challenging to quantify their impacts with certainty

Weak vs. Strong Sustainability in Policy-Making

Weak Sustainability:
- Justifies resource depletion if human-made capital can compensate for lost natural capital
- Might not be effective in addressing irreversible environmental changes like species extinction
Strong Sustainability:
- Emphasizes the irreplaceable nature of critical natural capital, advocating for their preservation
- More aligned with the precautionary principle, prioritizing the protection of essential resources
In the context of global environmental challenges like climate change and biodiversity loss, strong sustainability is often considered more appropriate due to the risks associated with irreversible environmental damage

The Anthropocene and Planetary Boundaries

The Anthropocene is a proposed geological epoch characterized by human-induced changes to the Earth system, including:
- Increased greenhouse gas concentrations
- Global warming and climate change
- Biodiversity loss and habitat degradation
- Pollution and resource depletion
The planetary boundaries framework, developed by Johan Rockström and colleagues, identifies nine Earth system processes with thresholds that, if crossed, could result in irreversible environmental changes, affecting the stability of the planet's life support system
The framework emphasizes the need for humanity to stay within these boundaries to ensure a safe operating space for human civilization.
