IB Geography B.3.2 Conflicting Land-use Pressures on Coastlines Notes

Coastal Space Creates Conflict Between Development and Conservation

1. Coastlines attract competing land uses because access to the sea, scenery, flat land and transport links create economic opportunities in the same narrow zone.
2. Tourism: Resorts, marinas and visitor infrastructure generate income and employment, but they can raise land prices, increase waste and place pressure on habitats.
3. Industry and ports: Deep water, shipping access and waterfront sites favour terminals and processing, but dredging, reclamation and pollution may damage fisheries and ecosystems.
4. Housing: Coastal property and urban growth meet demand for homes, but new exposure can lock governments into costly flood protection.
5. Conservation: Protected areas restrict damaging activities to preserve habitats, cultural values and ecosystem services, but limits on access can reduce some users' income.
6. Conflict intensifies when decisions allocate benefits to powerful investors while environmental costs or loss of access fall on local communities.
7. Cumulative pressure: Several individually permitted projects can together remove habitat, increase runoff and restrict public access beyond the effect predicted for any single development.
8. Land-sea linkage: Fertilizer, sediment and waste produced inland can reach estuaries and reefs, so a conflict that appears coastal may originate well beyond the shoreline.
9. Opportunity cost: Allocating waterfront land to a port, resort or protected habitat prevents some alternative uses, which is why zoning decisions create both winners and losers.

Zoning Separates Uses Without Removing Every Conflict

1. Marine and coastal zoning assigns different activities to specified areas, such as no-take conservation zones, tourism zones, shipping routes and general-use areas.
2. Zoning reduces direct incompatibility, but boundaries may displace fishing, concentrate visitors or leave land-based pollution outside the regulated area.
3. Permits and environmental impact assessment can attach conditions to projects, while setback lines keep vulnerable development away from an eroding shore.
4. Monitoring and enforcement determine whether rules change behaviour, because a protected area on a map does not protect ecosystems by itself.

1. Boundary design: Zones must follow ecological connections and actual patterns of use, because a line that ignores fish movement, currents or customary access can shift rather than solve conflict.
2. Displacement and leakage: Restricting an activity in one zone may intensify it elsewhere unless the plan controls total pressure and provides workable alternatives.
3. Compliance chain: Clear rules, visible boundaries, monitoring and proportionate sanctions are all required before a zoning map changes behaviour.

Integrated Coastal Management Coordinates Connected Decisions

1. Integrated coastal zone management treats the coast as one system that connects catchments, settlements, beaches and offshore waters.
2. It brings agencies and stakeholder groups together before decisions are fixed, reducing the risk that one sector solves its own problem by transferring costs to another.
3. Participation improves access to local and Indigenous knowledge, but consultation is weak if participants cannot influence the final decision or challenge unequal power.
4. A credible plan sets measurable objectives, publishes monitoring results and changes controls when environmental conditions or stakeholder needs change.
5. Management cycle: ICZM begins with a shared baseline, agrees measurable objectives, selects instruments, monitors outcomes and revises the plan when evidence shows that pressures or priorities have changed.
6. Meaningful participation: Stakeholders need early information, time to respond and a route for influencing choices, rather than consultation after the preferred option is already fixed.
7. Institutional scale: Catchment, municipal and marine authorities must coordinate because water, sediment, people and investment cross their administrative boundaries.

The Great Barrier Reef Concentrates Competing Stakeholders

1. Upstream responsibility: Agricultural land use affects marine water quality, which means Reef governance must influence practices outside the formal Marine Park boundary.
2. Multiple-use compromise: Zoning preserves stricter no-take areas while allowing regulated tourism, fishing and navigation elsewhere, so protection varies spatially instead of applying one rule to the whole system.
3. Rights and knowledge: Traditional Owners are not simply another interest group because Sea Country involves enduring rights, cultural responsibilities and place-based ecological knowledge.

Decision-Making Reflects Unequal Power and Different Values

1. Government agencies possess legal authority, data and enforcement resources, but political priorities and industry pressure can influence how those powers are used.
2. Large firms can fund technical evidence and lobbying, while smaller tourism operators, fishers and coastal residents may depend more directly on local access.
3. Traditional Owners contribute rights, cultural values and place-based knowledge that cannot be reduced to the same financial measures used for commercial projects.
4. Conservation groups can mobilize public attention and scientific evidence, but they may still disagree with livelihood groups about the speed and location of restrictions.
5. The outcome is therefore not simply conservation versus development, but a negotiated distribution of access, risk, cost and decision-making authority.
6. Resource asymmetry: Actors with legal expertise, finance and regular access to officials can shape evidence and agendas more easily than dispersed residents or small-scale users.
7. Procedural justice: A decision may improve ecological indicators yet remain contested if affected people cannot understand the evidence, challenge assumptions or appeal the result.

Reef Management Produces Gains but Cannot Remove Climate Risk

1. Zoning and permits can reduce direct local pressures such as extraction, anchor damage and incompatible uses.
2. Catchment programs can improve water quality, although progress depends on actions beyond the Marine Park boundary and on sustained funding.
3. Partnerships with Traditional Owners can strengthen legitimacy and connect ecological objectives with cultural responsibilities for Sea Country.
4. Local management can improve resilience, but it cannot by itself prevent marine heatwaves driven by global greenhouse gas emissions.
5. An effective judgement therefore separates what local institutions can control from climate pressures that require national and international action.
6. Controllable pressures: Local institutions can regulate extraction, anchoring, runoff and visitor behaviour, thereby improving the condition from which reefs confront heat stress.
7. Climate constraint: Repeated marine heatwaves can overwhelm local resilience gains, so reef management and global emissions reduction are complementary rather than interchangeable.

Evaluation Should Test Process as Well as Outcome

1. A fair process gives affected groups early access to information, a meaningful voice and a reasoned explanation of the final decision.
2. An effective outcome protects ecological function while keeping permitted uses within environmental limits that can be monitored.
3. An equitable outcome does not require identical benefits, but it should avoid concentrating losses on groups with the least influence or capacity to adapt.
4. Three dimensions: Evaluation should distinguish ecological effectiveness, economic viability and procedural fairness because progress in one dimension can conceal failure in another.
5. Counterfactual: Managers should compare observed change with what would probably have occurred without the policy instead of attributing every improvement to the intervention.
