Conservation and sustainability: approaches, strategies, examples

Conservation and Sustainability – A‑Level Geography (Cambridge 9696)

1. Objective

To understand the main approaches and strategies used to conserve natural resources and promote sustainability, to evaluate their effectiveness using quantitative and qualitative indicators, and to apply this knowledge to detailed, time‑bound case studies that illustrate scale, place, change over time and cause‑effect relationships.

4. Approaches to Conservation

5. Strategies for Sustainable Management (with brief evaluation)

1. Protected‑Area Networks
   • Actions: Designation of national parks, wildlife sanctuaries, marine protected areas; creation of ecological corridors.
   • Strengths: Secures large, intact habitats; supports flagship species; provides ecosystem‑service buffers.
   • Limitations: May restrict traditional land‑use, cause “fortress conservation” conflicts; enforcement often under‑resourced.
   • Indicators: % of country’s land/water under protection; number of illegal incursions recorded.
2. Sustainable Use of Resources
   • Actions: Certification schemes (FSC, MSC), quota systems, seasonal closures, community‑managed fisheries.
   • Strengths: Aligns market incentives with conservation; can generate premium prices.
   • Limitations: Requires robust traceability; illegal trade can undermine schemes.
   • Indicators: Certified area (% of total forest); compliance rate (% of quota adhered to); economic return per hectare.
3. Restoration and Rehabilitation
   • Actions: Re‑forestation, afforestation, mangrove planting, invasive‑species removal, soil remediation.
   • Strengths: Re‑establishes ecosystem services; creates green jobs; can improve climate‑mitigation capacity.
   • Limitations: High upfront costs; success depends on site‑specific ecology and post‑planting care.
   • Indicators: Survival rate of planted seedlings after 3 years; carbon sequestration (t CO₂ ha⁻¹ yr⁻¹); increase in habitat connectivity (m² of linked core area).
4. Policy Instruments
   • Legislative & International Agreements
     • Convention on Biological Diversity (CBD, 1992)
     • CITES (1975)
     • Ramsar Convention on Wetlands (1971)
     • EU Habitats & Birds Directives (1992)
     • US Endangered Species Act (1973)
   • Economic Tools
     • Taxes & subsidies (e.g., carbon tax, agri‑environmental subsidies)
     • Payments for Ecosystem Services (PES) – UK Countryside Stewardship, Costa Rica’s PES programme.
   • Evaluation: Legal frameworks provide clear duties and penalties, but effectiveness hinges on enforcement capacity, political will and the availability of funding.
   • Indicators: Number of statutes enacted; compliance rate (% of violations prosecuted); PES payments disbursed (£ M/yr).
5. Education, Public Awareness & Citizen Science
   • Actions: School curricula, community workshops, media campaigns, citizen‑science platforms (e.g., iRecord, eBird).
   • Strengths: Builds long‑term stewardship; generates large, cost‑effective data sets.
   • Limitations: Behaviour change can be slow; requires sustained funding and data‑quality control.
   • Indicators: Number of participants; volume of records submitted; % increase in public support for conservation (survey).

7. Illustrative Examples

7.1 Global High‑Income Cases (Scale: National to Global)

• Yellowstone National Park (USA) – First modern national park (1872); wolf re‑introduction (1995‑2020) increased elk‑coyote balance and riparian vegetation by 23 %.
• Global Seed Vault (Svalbard, Norway) – Stores >1 million seed samples; viability testing shows 94 % germination after 10 years.
• Great Barrier Reef Marine Park (Australia) – Zoning plan (2004) protects 33 % of reef; coral cover has stabilised at 45 % after a decade of bleaching events.

7.2 Middle‑Income Examples (Scale: Community to National)

• Community Forests – Nepal – 1 500 community‑managed forest groups; household income from non‑timber forest products rose 18 % (2010‑2020); illegal logging incidents fell 60 %.
• Marine Protected Areas – Fiji – 30 % of EEZ designated; reef fish biomass increased 150 % within MPAs compared with adjacent fished areas.

7.3 Low‑Income Examples (Scale: Local to Trans‑boundary)

• Wildlife Management Areas – Tanzania – Community‑run conservancies covering 12 % of protected land; lion populations grew from 300 (2005) to 560 (2022); tourism revenue now funds 70 % of school fees in adjacent villages.
• Lake Victoria Basin Restoration (Uganda/Kenya/Tanzania) – Phytoplankton reduction programmes cut cyanobacterial blooms by 40 % (2016‑2022), improving fisheries yields.

7.4 Detailed Local Case Study – River Thames Catchment (UK, 2015‑2023)

Goal: Integrate flood risk management, water‑quality improvement and biodiversity restoration under the EU Water Framework Directive (transposed into UK law).

1. Key Actions
   • Installation of Sustainable Urban Drainage Systems (SUDS) in 85 % of new developments.
   • Re‑creation of 12 km of riparian buffers, raising native vegetation cover by 38 %.
   • Stakeholder partnership: Environment Agency, local authorities, NGOs (Thames River Trust), water companies and community groups.
2. Quantitative Outcomes (2015‑2023)
   • Nitrate concentrations in the upper Thames fell from 8 mg L⁻¹ to 4.5 mg L⁻¹ (‑44 %).
   • Macro‑invertebrate Index of Biotic Integrity (IBI) scores improved from “poor” to “good” at 7 of 10 monitoring sites.
   • Flood‑risk to downstream urban areas reduced by an estimated £12 million in avoided damages per decade.
   • Economic return from eco‑tourism along restored river sections increased by £3 million (2015‑2023).
3. Evaluation (AO3)
   • Successes: Clear water‑quality improvements, measurable biodiversity gains, strong multi‑agency governance, and demonstrable economic benefits.
   • Limitations: Persistent upstream agricultural runoff; long‑term funding for monitoring uncertain; climate‑induced extreme flow events.
   • Lesson: Adaptive management, continuous stakeholder engagement and integrated monitoring are essential for sustaining gains.

7.5 Place‑Based Comparison (High‑, Middle‑ and Low‑Income Contexts)

8. Systems Diagram – How Conservation Works (Textual Flow)

Inputs: International conventions, national legislation, financial resources (taxes, PES, donor aid), scientific data (remote sensing, DNA barcoding).
Processes: Planning (zoning, target‑setting), implementation (protected‑area establishment, restoration works, certification), monitoring & evaluation (indicators, citizen‑science data).
Outputs: Ecological outcomes (species recovery, improved water quality), social outcomes (livelihood benefits, community empowerment), economic outcomes (tourism revenue, cost‑savings from flood mitigation).
Feedback Loops: Monitoring results inform policy revisions (adaptive management) and affect funding allocations.

10. Challenges and Future Directions

• Climate Change: Species range shifts demand dynamic protected‑area networks and climate‑smart restoration.
• Land‑Use Conflict: Balancing agriculture, infrastructure and biodiversity requires integrated spatial planning tools.
• Funding Gaps: Long‑term monitoring and restoration need stable financing mechanisms (e.g., green bonds, blended finance).
• Cross‑Border Management: Trans‑national river basins and migratory species call for joint governance (e.g., Mekong River Commission).
• Emerging Technologies: Remote sensing for real‑time habitat monitoring; DNA barcoding for illegal wildlife trade detection; AI‑driven predictive models for ecosystem services.
• Social Inclusion: Strengthening gender‑responsive and indigenous‑rights‑based approaches to ensure equitable benefit‑sharing.

11. Summary

Effective conservation and sustainability hinge on a blend of approaches—protecting ecosystems in place, safeguarding genetic resources ex‑situ, and empowering local communities. Translating these approaches into action involves protected‑area networks, sustainable‑use schemes, restoration programmes, robust policy instruments and education. Quantitative case studies such as the River Thames Basin Management Plan illustrate measurable ecological and socio‑economic gains, while also highlighting ongoing challenges. Systematic evaluation using ecological, social, economic and governance criteria, together with adaptive management, is essential for long‑term success across scales, places and changing conditions.
