From the Executive Summary: "Tourism provides livelihoods for millions of people and allows billions more to appreciate their own and different cultures, as well as the natural world. For some countries, it can represent over 20 per cent of their GDP [gross domestic product] and, overall, it is the third largest export sector of the global economy. Tourism is one of the sectors most affected by the COVID-19 [coronavirus disease 2019] pandemic, impacting economies, livelihoods, public services and opportunities on all continents. While sustaining the livelihoods dependent on the sector must be a priority, rebuilding tourism is also an opportunity for transformation with a focus on leveraging its impact on destinations visited and building more resilient communities and businesses through innovation, digitalization, sustainability, and partnerships."
