For many living in the countryside without access to employment in extractive industries, remittances from family members in urban areas or subsistence activities provide income.
They consist of workers' housing, a variety of commercial and social buildings, and a modern draft entry mine with accompanying extractive buildings and structures.
While these are not designed for extractive use, some forms of extraction are often allowed and these protected areas certainly allow for non-extractive uses.
Traditionally, project financing has been most commonly used in the extractive (mining), transportation, telecommunications industries as well as sports and entertainment venues.
