due to the effect of governmental policies. The report also noted that 10 percent of the Thai population earned 35 percent of Thailand's aggregate income and owned 61.5 percent of its land. Thailand was ranked as the world's third most unequal nation, behind Russia and India, in the Credit Suisse Global Wealth Databook 2016 (companion volume to the Global Wealth Report 2016), with one percent of the Thai population estimated to own 58 percent of Thailand's wealth. Industries SMEs Virtually all of Thailand's firms, 99.7 percent, or 2.7 million enterprises, are classed as being small or medium-sized enterprises (SMEs). , SMEs account for 80.3 percent (13 million) of Thailand's total employment. In sheer numbers SMEs predominate, but their contribution to the nation's GDP decreased from 41.3 percent of GDP in 2002 to 37.4 percent in 2013. Their declining contribution is reflected in their turnover rate: seventy percent fail within "...a few years". Agriculture, forestry and fishing Developments in agriculture since the 1960s have supported Thailand's transition to an industrialised economy. As recently as 1980, agriculture supplied 70 percent of employment. In 2008, agriculture, forestry and fishing contributed 8.4 percent to GDP; in rural areas, farm jobs supply half of employment. Rice is the most important crop in the country and Thailand had long been the world's number one exporter of rice, until recently falling behind both India and Vietnam. It is a major exporter of shrimp. Other crops include coconuts, corn, rubber, soybeans, sugarcane and tapioca. Thailand is the world's third-largest seafood exporter. Overall fish exports were worth around US$3 billion in 2014, according to the Thai Frozen Foods Association. Thailand's fishing industry employs more than 300,000 persons. In 1985, Thailand designated 25 percent of its land area for forest protection and 15 percent for timber production. Forests have been set aside for conservation and recreation, and timber forests are available for the forestry industry. Between 1992 and 2001, exports of logs and sawn timber increased from 50,000 to 2,000,000 cubic meters per year. The regional avian-flu outbreak contracted Thailand's agricultural sector in 2004, and the tsunami of 26 December devastated the Andaman Sea fishing industry. In 2005 and 2006, agricultural GDP was reported to have contracted by 10 percent. Thailand is the world's second-largest exporter of gypsum (after Canada), although government policy limits gypsum exports to support prices. In 2003 Thailand produced more than 40 different minerals, with an
