Tourism Growth and Carrying Capacity on a Heritage Coast
A coastal national park of 380 km² receives 1.9 million visitors per year, up from 1.1 million a decade ago. The park has 46 km of walking trails, 9 beaches and a single access road. Visitor surveys show 71% arrive by private car, peak-day beach occupancy reaches 4.2 people per metre of shoreline, and dune vegetation loss along the main beach has been 12% over 8 years. Local businesses employ 2,300 people and generate $310 million annually. The park authority is considering a daily visitor cap of 6,000 at the main beach, a shuttle from a park-and-ride 14 km away, and a trail permit fee.
1. Assess whether the proposed measures address the causes of pressure or only the symptoms.

The pressures have distinct causes: car dependence (71% by private car) concentrates arrivals on one road and one beach; peak-day occupancy of 4.2 people per metre exceeds comfortable capacity; and dune loss of 12% in 8 years is a physical impact of foot traffic and parking.
The shuttle addresses the cause of road and parking pressure by changing mode share, but only if it is frequent, cheap and faster than driving - otherwise it will be used by a minority and the road remains congested. The daily cap addresses peak concentration directly and is the most reliable tool for limiting occupancy, but a cap at the main beach may simply displace visitors to the other 8 beaches unless applied park-wide or paired with dispersal measures. The trail permit fee manages demand on trails and raises revenue for maintenance, but trails are not where the dune loss is occurring; it does little for the beach.
So the package is mixed: the cap and shuttle target causes at the main beach, while the permit fee is largely a revenue and symptom-management measure. Dispersal to less-visited beaches and dune protection works are missing.
2. Recommend how the three measures should be sequenced and combined, with reasoning about visitor behaviour.

Sequence matters because measures interact. The shuttle should be introduced first, with improved frequency and a fare included in park entry, so that when the cap is imposed visitors have a viable alternative to being turned away. Imposing the cap first would generate displacement and conflict without reducing total demand.
The cap should then apply to the whole park's main access points, not just one beach, to prevent displacement to the other eight beaches. It should be set from occupancy data - 6,000 at the main beach is defensible if it keeps occupancy within capacity - and varied seasonally so quiet days are not restricted.
The trail permit fee should be modest and reinvested visibly in dune protection and trail maintenance, because fees perceived as revenue-raising without visible benefit erode compliance. Dune fencing and boardwalks should accompany it, since the 12% vegetation loss needs direct physical protection, not just pricing.
The combination works because the shuttle changes mode, the cap changes volume and distribution, and the fee funds the protection that maintains the asset attracting 1.9 million visitors.
3. Explain the tension between conservation and the $310 million local economy, and how a carrying-capacity approach manages it.
Read the worked answer
Tourism generates $310 million and 2,300 jobs, so restricting visitor numbers has direct economic costs concentrated on local businesses. But the park's natural assets are the reason for the visitation; dune loss of 12% in 8 years, if unchecked, degrades the very resource that sustains the economy. The tension is therefore between short-term revenue and long-term asset condition.
Carrying capacity reframes the issue: the question is not how many visitors are acceptable economically but how much use the resource can sustain without unacceptable change. Setting limits from ecological indicators - dune vegetation condition, trail erosion, occupancy - and monitoring them gives an objective basis for the cap, and allows it to rise if conditions improve.
This manages the tension by making the trade-off explicit and reversible. Businesses face a defined, monitored limit rather than an open-ended decline, and revenue from fees can be reinvested in the asset. The cap protects the economy's foundation rather than undermining it.
