From the paper:
Deficiencies in Belize’s transport infrastructure hamper trade and economic growth. Despite notable progress in the last decade, the extent and quality of transport infrastructure in Belize still lags behind other developing countries in the Latin American and Caribbean (LAC) region. Deficiencies in road infrastructure and ports constitute an important and costly barrier to international trade. Moreover, limited connectivity with neighboring countries is an impediment to Belize’s closer economic integration with Central America and Mexico. Poor accessibility to extensive areas of land in the country’s interior, particularly in the South and during the rainy season, not only affects agricultural production and limits the use of the country's historical and ecotourism sites, but also impacts human development in the rural population.
