MDG Nature-Based Tourism Impact Report Summary

Methodology

• LEWIE-LITE Tool: A simplified model using social accounting matrices (SAM) to estimate local economic impacts of tourism. Data collected through surveys from diverse local economy actors (tourists, businesses, households) around Ranomafana National Park and Nosy Tanikely National Marine Park.

Key Findings

• An average tourist spends $144 at Ranomafana and $190 at Nosy Tanikely, with differing leakage rates:
  • At Ranomafana, 41% of spending leaks out.
  • At Nosy Tanikely, tourism-related spending leaks 40-37%, but nontourism leaks 68-28%.
• Multipliers indicate tourism spending generates broader economic benefits:
  • Every dollar at Nosy Tanikely increases local production by $4.36 and income by $2.48.
  • Every dollar at Ranomafana increases production by $1.75 and income by $0.71.
• Poor households benefit significantly from tourism: 32% of income at Ranomafana and 56% at Nosy Be.

Policy Recommendations

• Strengthen Local Sourcing: Tailor policies to enhance local market linkages for tourism businesses to minimize leakage.
• Scale Benefit Sharing: Formalize revenue-sharing mechanisms to maximize local economic participation in protected areas.
• Support Employment Programs: Leverage tourism to boost job training, especially for women and marginalized groups like poor households.

Practical Application

• LEWIE-LITE Tool: Scalable for quick, data-driven economic impact assessments. Effective for monitoring positive/negative shocks, policy simulations, and guiding investment.

Limitations

• Scale: Suitable for data-poor contexts but may not capture price changes or complex nonlinear effects.
• Assumptions: Fixed prices and no elasticity in supply response may affect accuracy for large-scale tourism changes.
