Human–Environment Interaction & Sustainable Development

Human–Environment Interaction humans और environment के बीच mutual relationship है — humans environment को modify करते हैं और environment humans को influence करता है।

Key Aspects:

• Humans depend on environment: Air, water, food, resources
• Humans modify environment: Deforestation, pollution, urbanization
• Environment affects humans: Climate, disasters, resource availability

Anthropogenic Activities humans द्वारा की गई वे activities हैं जो environment को impact करती हैं।

Major Anthropogenic Activities:

• Deforestation — वनोन्मूलन: Clearing forests for agriculture, urbanisation, industries
• Industrialisation — औद्योगीकरण: Air, water, land pollution; resource depletion
• Urbanisation — नगरीकरण: Land use change, heat island effect, waste generation
• Agriculture — कृषि: Use of fertilisers, pesticides, irrigation, monoculture
• Fossil Fuel Burning — जीवाश्म ईंधन जलाना: CO₂ emissions, air pollution, climate change
• Mining — खनन: Land degradation, water pollution, loss of biodiversity
• Overfishing — अत्यधिक मछली पकड़ना: Marine ecosystem imbalance
• Waste Generation — अपशिष्ट उत्पादन: Plastic pollution, e-waste, landfill issues
• Transportation — परिवहन: Emissions, noise pollution, habitat fragmentation

Development और Environment के बीच trade-off है — development के लिए resources चाहिए, जो environment से आते हैं।

Key Issues:

• Resource Depletion — संसाधनों की कमी: Natural resources are finite
• Environmental Degradation — पर्यावरणीय क्षरण: Pollution, deforestation, biodiversity loss
• Climate Change — जलवायु परिवर्तन: Greenhouse gas emissions from development activities
• Displacement — विस्थापन: Development projects often displace communities

Approaches:

• Economic Growth vs Environmental Protection: Need balance
• Sustainable Development: Meeting present needs without compromising future

Sustainable Development वह development है जो present generation की needs को future generations की ability से समझौता किए बिना पूरा करता है।

Brundtland Report (1987):

• First defined sustainable development
• Report of the World Commission on Environment and Development (WCED)
• Also known as "Our Common Future"

Three Pillars of Sustainable Development:

• Economic — आर्थिक: Growth, efficiency, innovation
• Social — सामाजिक: Equity, inclusion, participation
• Environmental — पर्यावरणीय: Conservation, resource management

Sustainable Development Goals (SDGs) 17 global goals हैं — adopted by UN in 2015 — to be achieved by 2030.

• SDG 1: No Poverty
• SDG 2: Zero Hunger
• SDG 3: Good Health and Well-being
• SDG 4: Quality Education
• SDG 5: Gender Equality
• SDG 6: Clean Water and Sanitation
• SDG 7: Affordable and Clean Energy
• SDG 8: Decent Work and Economic Growth
• SDG 9: Industry, Innovation and Infrastructure
• SDG 10: Reduced Inequality
• SDG 11: Sustainable Cities and Communities
• SDG 12: Responsible Consumption and Production
• SDG 13: Climate Action
• SDG 14: Life Below Water
• SDG 15: Life on Land
• SDG 16: Peace, Justice and Strong Institutions
• SDG 17: Partnerships for the Goals

Intergenerational Equity का अर्थ है present generation को environment और resources का उपयोग इस प्रकार करना चाहिए कि future generations भी अपनी needs पूरी कर सकें।

Key Points:

• Resources should be sustainable — not exhausted
• Environment should be protected for future
• Future generations should have same opportunities
• Core principle of Sustainable Development

Intragenerational Equity का अर्थ है current generation के भीतर fairness and justice — resources और benefits का equitable distribution.

Key Points:

• Resources should be equitably shared among all people
• Developing and developed countries should have fair responsibility
• Marginalised and vulnerable groups should be protected
• Climate justice is part of intragenerational equity

Carrying Capacity किसी environment की maximum population size है जिसे वह sustain कर सकता है — बिना degradation के।

Key Points:

• Determined by resources (food, water, space)
• Exceeding carrying capacity leads to degradation
• Human activities can increase or decrease carrying capacity
• Population growth must respect carrying capacity

Polluter Pays Principle (PPP) के अनुसार जो pollutes (प्रदूषण फैलाता है) उसे cost (cleanup, compensation, damage) भी वहन करनी चाहिए।

Key Points:

• Polluter should bear the cost of pollution
• Encourages prevention and cleaner technologies
• Internalises external costs
• Recognised in environmental law (national and international)

Precautionary Principle के अनुसार यदि किसी activity से environmental harm का risk है, तो scientific certainty न होने पर भी preventive measures लिए जाने चाहिए।

Key Points:

• Lack of scientific certainty is not an excuse for inaction
• Preventive action should be taken before damage occurs
• Burden of proof lies with the proponent (activity proposer)
• Widely used in environmental policy and climate change

• Polluter Pays Principle: Polluter bears the cost
• Precautionary Principle: Prevention despite scientific uncertainty
• Intergenerational Equity: Fairness to future generations
• Intragenerational Equity: Fairness within current generation
• Common But Differentiated Responsibilities (CBDR): Developed countries should take more responsibility
• Public Trust Doctrine: Natural resources are held in trust by the state for the public
• Principle of Sustainable Development: Balance economy, society, environment

EIA एक process है जो किसी proposed project/activity के environmental consequences का assessment करता है — before approval.

Steps:

• Screening: Whether EIA is required
• Scoping: Which impacts to study
• Impact Assessment: Identifying and predicting impacts
• Mitigation: Measures to reduce negative impacts
• Reporting: EIA report/document
• Review: Independent review of EIA
• Decision: Approval or rejection

• Trap 1: Sustainable development = only environmental protection → ❌ It includes economic and social dimensions too.
• Trap 2: Intergenerational = intragenerational → ❌ Intergenerational is between generations; intragenerational is within the same generation.
• Trap 3: Polluter Pays = polluter pays only for cleanup → ❌ Includes compensation, prevention, and restoration costs.
• Trap 4: Precautionary Principle = always stop all activities → ❌ It requires preventive action, not necessarily a ban.
• Trap 5: Carrying capacity = fixed number → ❌ Can change with technology, resource management.
• Trap 6: SDGs adopted in 2000 → ❌ SDGs adopted in 2015 (MDGs were 2000).
• Trap 7: Brundtland Report = 1992 → ❌ Brundtland Report was 1987 (Rio Summit was 1992).

The Polluter Pays Principle means:

• B. Polluters should bear the cost of pollution

Explanation: The Polluter Pays Principle states that those who pollute should bear the costs of pollution control and remediation.

The Precautionary Principle is applied when:

• A. There is no risk
