🪺Environmental Biology Unit 9 – Sustainable Development & Policy

Key Concepts in Sustainable Development

• Sustainable development meets the needs of the present without compromising future generations' ability to meet their own needs
• Involves balancing economic growth, social equity, and environmental protection
• Requires a long-term perspective considering the impacts of current actions on future generations
• Emphasizes the efficient use of natural resources and minimizing waste production
• Promotes the use of renewable energy sources (solar, wind) to reduce reliance on fossil fuels
• Encourages sustainable consumption patterns and responsible production practices
• Aims to eradicate poverty and improve quality of life for all individuals
• Recognizes the interconnectedness of social, economic, and environmental systems

Environmental Challenges and Their Impacts

• Climate change caused by greenhouse gas emissions leads to rising sea levels, more frequent extreme weather events, and shifts in ecosystems
• Deforestation results in biodiversity loss, soil erosion, and disruption of water cycles
• Air pollution from industrial activities and transportation contributes to respiratory illnesses and acid rain
• Water scarcity and pollution threaten access to clean drinking water and impact agricultural productivity
• Soil degradation from unsustainable farming practices reduces land fertility and food security
  • Overgrazing, monoculture farming, and excessive use of pesticides and fertilizers contribute to soil degradation
• Ocean acidification due to increased carbon dioxide absorption harms marine ecosystems and coral reefs
• Plastic pollution accumulates in the environment, harming wildlife and entering the food chain
• Urbanization and population growth strain natural resources and contribute to environmental degradation

Sustainable Development Goals (SDGs)

• The United Nations adopted 17 SDGs in 2015 as a global framework for sustainable development
• SDG 1: End poverty in all its forms everywhere
• SDG 2: End hunger, achieve food security and improved nutrition, and promote sustainable agriculture
• SDG 3: Ensure healthy lives and promote well-being for all at all ages

• SDG 5: Achieve gender equality and empower all women and girls
• SDG 6: Ensure availability and sustainable management of water and sanitation for all
• SDG 7: Ensure access to affordable, reliable, sustainable, and modern energy for all
  • Targets include increasing the share of renewable energy and improving energy efficiency
• SDG 8: Promote sustained, inclusive, and sustainable economic growth, full and productive employment, and decent work for all
• SDG 9: Build resilient infrastructure, promote inclusive and sustainable industrialization, and foster innovation
• SDG 10: Reduce inequality within and among countries
• SDG 11: Make cities and human settlements inclusive, safe, resilient, and sustainable
• SDG 12: Ensure sustainable consumption and production patterns
• SDG 13: Take urgent action to combat climate change and its impacts
• SDG 14: Conserve and sustainably use the oceans, seas, and marine resources for sustainable development
• SDG 15: Protect, restore, and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, halt and reverse land degradation, and halt biodiversity loss
• SDG 16: Promote peaceful and inclusive societies for sustainable development, provide access to justice for all, and build effective, accountable, and inclusive institutions at all levels
• SDG 17: Strengthen the means of implementation and revitalize the global partnership for sustainable development

Policy Frameworks for Sustainability

• The United Nations Framework Convention on Climate Change (UNFCCC) provides a global platform for addressing climate change
  • The Paris Agreement, adopted under the UNFCCC, aims to limit global temperature rise and promote climate resilience
• The Convention on Biological Diversity (CBD) aims to conserve biodiversity, sustainably use its components, and ensure fair and equitable sharing of benefits from genetic resources
• The United Nations Convention to Combat Desertification (UNCCD) focuses on combating desertification, land degradation, and drought
• The Basel Convention regulates the transboundary movement and disposal of hazardous wastes
• The Montreal Protocol successfully phased out ozone-depleting substances to protect the ozone layer
• National and local governments develop policies and regulations to promote sustainable practices (renewable energy targets, energy efficiency standards)
• Market-based instruments (carbon taxes, emissions trading schemes) incentivize the reduction of greenhouse gas emissions
• Voluntary sustainability standards and certification schemes (Forest Stewardship Council, Rainforest Alliance) promote sustainable production practices

Economic Aspects of Sustainable Development

• Sustainable development requires decoupling economic growth from environmental degradation
• Green economy promotes low-carbon, resource-efficient, and socially inclusive economic activities
• Circular economy aims to minimize waste and maximize resource efficiency through reuse, recycling, and recovery
• Sustainable finance incorporates environmental, social, and governance (ESG) factors into investment decisions
• Internalizing environmental externalities (pollution costs) through taxes or regulations encourages sustainable practices
• Sustainable tourism balances economic benefits with environmental conservation and local community well-being
• Sustainable supply chain management considers the environmental and social impacts of products throughout their life cycle
• Sustainable agriculture practices (organic farming, agroforestry) promote long-term productivity and ecosystem health

Social Dimensions of Sustainability

• Social sustainability focuses on ensuring equitable access to resources, opportunities, and decision-making processes
• Poverty eradication is essential for sustainable development, as poverty exacerbates environmental degradation and social inequality
• Gender equality and women's empowerment are crucial for sustainable development, as women play vital roles in resource management and community well-being
• Access to education and healthcare is essential for building human capital and promoting sustainable practices
• Inclusive and participatory decision-making processes ensure that the needs and perspectives of all stakeholders are considered
• Indigenous knowledge and traditional practices can contribute to sustainable resource management and biodiversity conservation
• Sustainable urban development promotes livable, resilient, and inclusive cities through integrated planning and community engagement
• Social protection systems (healthcare, unemployment benefits) enhance resilience and support sustainable livelihoods

Environmental Management Strategies

• Ecosystem-based management considers the interactions and dependencies between human activities and natural systems
• Protected areas (national parks, marine reserves) conserve biodiversity and provide ecosystem services
• Integrated water resources management balances competing demands for water while ensuring sustainable use and ecosystem health
• Sustainable forest management practices (reduced impact logging, forest certification) balance timber production with conservation and community needs
• Sustainable fisheries management (catch limits, marine protected areas) ensures long-term productivity and ecosystem resilience
• Sustainable land management practices (terracing, cover cropping) prevent soil erosion and maintain soil fertility
• Integrated pest management combines biological, cultural, and chemical control methods to minimize pesticide use and protect ecosystem health
• Sustainable waste management hierarchies prioritize waste prevention, reuse, recycling, and recovery over disposal
