The economy, one of the world's smallest and least developed, is based on agriculture and forestry, which provide the main livelihood for more than 90% of the population. Agriculture consists largely of subsistence farming and animal husbandry. Rugged mountains dominate the terrain and make the building of roads and other infrastructure difficult and expensive. The economy is closely aligned with India's through strong trade and monetary links and dependence on India's financial assistance. The industrial sector is technologically backward, with most production of the cottage industry type. Most development projects, such as road construction, rely on Indian migrant labor. Bhutan's hydropower potential and its attraction for tourists are key resources. Model education, social, and environment programs are underway with support from multilateral development organizations. Each economic program takes into account the government's desire to protect the country's environment and cultural traditions. For example, the government in its cautious expansion of the tourist sector encourages the visits of upscale, environmentally conscientious visitors. Detailed controls and uncertain policies in areas like industrial licensing, trade, labor, and finance continue to hamper foreign investment.
