Thailand's dramatic economic growth has caused numerous environmental issues. The country faces problems with air, declining wildlife populations, deforestation, soil erosion, water scarcity, and waste issues. According to a 2004 indicator, the cost of air and water pollution for the country scales up to approximately 1.6–2.6% of GDP per year. As such, Thailand's economic growth has come at great cost in damage to its people and environment. Thailand's Twelfth National Economic and Social Development Plan (2017-2021) warns that, "At present the country's natural resources and environmental quality are deteriorating, and have become a weakness in maintaining the basis of production, services and sustainable living. A large volume of the natural resources stock has been utilized for development, resulting in their continuous degradation. The forests have been depleted, the soil has become infertile, and biodiversity has been threatened. While exhibiting a future risk of water shortages, the existing supply of water has not been able to meet the demands of the various sectors. Conflicts over the use of natural resources stem from the unfair allocation of access and exploitation. Moreover, environmental problems have risen along with economic growth and urbanization. All of these problems have affected the quality of life and have added greater economic costs." Climate change Deforestation Forest cover in Thailand has been greatly reduced as people convert forested land to agriculture, or misappropriate public lands for private use, with related estimates varying. The Sueb Nakhasathien Foundation reports that 53% of Thailand was covered by forest in 1961, but that forested areas had shrunk to 31.6% in 2015. An estimate by the World Wildlife Fund concluded that between 1973 and 2009, Thailand's forests declined by 43%. During the period 2001–2012, Thailand lost one million hectares of forest, while restoring 499,000 hectares. Between 1990 and 2005, Thailand lost 9.1% of its forest cover, or around 1,445,000 hectares. , Thailand has an average annual deforestation rate of 0.72%. Wetlands have been converted to rice paddies and urban sprawl. With government measures in place to prohibit logging, deforestation rates have dropped, but the impacts of deforestation are still being felt. Thai government numbers show an increase in the extent of Thai forests. Figures from the Center for Agricultural Information of Thailand's Ministry of Agriculture and Cooperatives show an increase in the extent of Thailand's forested area over the period 2006-2015 (from 99 million rai to 103 million rai), with decreases in every
