CROP DIVERSIFICATION IN THAILANDChavalvut Cha<strong>in</strong>uvati * and Withaya Athipanan **1. INTRODUCTIONThailand is located <strong>in</strong> <strong>the</strong> Indoch<strong>in</strong>a Pen<strong>in</strong>sula with a total area of about 51.36 millionhectares. Her territorial boundaries connect with Malaysia <strong>in</strong> <strong>the</strong> south, Cambodia <strong>in</strong> <strong>the</strong>nor<strong>the</strong>ast to east, Laos <strong>in</strong> <strong>the</strong> nor<strong>the</strong>ast, and Myanmar <strong>in</strong> <strong>the</strong> northwest to west.Geographically, <strong>the</strong> country may be divided <strong>in</strong>to four <strong>region</strong>s. In <strong>the</strong> central,nor<strong>the</strong>rn, nor<strong>the</strong>astern and sou<strong>the</strong>rn <strong>region</strong>s, altitude modifies <strong>the</strong> temperature considerably.It is cool enough <strong>in</strong> <strong>the</strong> nor<strong>the</strong>rn <strong>region</strong> to produce temperate fruits and vegetables (alsovegetable seeds); cool and dry <strong>in</strong> nor<strong>the</strong>ast <strong>region</strong>, and modestly humid <strong>in</strong> <strong>the</strong> central <strong>region</strong>.These three <strong>region</strong>s have three seasons: ra<strong>in</strong>y dur<strong>in</strong>g late April to October, w<strong>in</strong>ter fromNovember to February, and summer from March until April. In <strong>the</strong> sou<strong>the</strong>rn <strong>region</strong>, <strong>the</strong>re isno cool season and <strong>the</strong> climate is wet, but with less solar radiation than is needed formaximum crop yields. Thailand’s climate is tropical and monsoonal, <strong>in</strong>fluenced by <strong>the</strong>southwest monsoon except for <strong>the</strong> south. Average annual ra<strong>in</strong>fall and temperature vary,rang<strong>in</strong>g from 998-4,603 mm of precipitation and a temperature regime of 24.4-29.3 o C (76-85 o F).Adm<strong>in</strong>istratively, Thailand is divided <strong>in</strong>to 76 prov<strong>in</strong>ces, each headed by a governor.There are 787 districts and district branches, 7,404 sub-districts, and nearly 66,604 villages<strong>in</strong> <strong>the</strong> 76 prov<strong>in</strong>ces. The population <strong>in</strong> 1996 was over 60 million people, and of thispopulation 64 percent reside <strong>in</strong> <strong>the</strong> rural areas. Approximately 90 percent of <strong>the</strong> rural people,or 5.2 million farm families, earn <strong>the</strong>ir <strong>in</strong>come through subsistence farm<strong>in</strong>g, particularly ricecultivation and o<strong>the</strong>r field crop production.In Thailand, 64 percent of <strong>the</strong> population are engaged <strong>in</strong> agriculture. Most of <strong>the</strong>mgrow s<strong>in</strong>gle crops such as rice, cassava, corn, sugar cane etc. The proportion of <strong>in</strong>come percapita of those engaged <strong>in</strong> agriculture to o<strong>the</strong>r sectors was 1:13 <strong>in</strong> 1997. Severaldevelopment programmes have failed because <strong>the</strong>re were no realistic assessments of <strong>the</strong>limited resource base of small farm<strong>in</strong>g systems.The survival and social-economic pattern of <strong>the</strong> householders was not taken <strong>in</strong>to fullaccount. The basic assumption is that small-scale farmers <strong>in</strong> Thailand will be responsive todevelopment efforts if <strong>the</strong> technology fits <strong>the</strong>ir needs, aspirations and environments.The Department of Agricultural Extension (DOAE) has realized such drawbacks andput more efforts to solve <strong>the</strong>se k<strong>in</strong>ds of problems. The strategy is <strong>in</strong> l<strong>in</strong>e with <strong>the</strong>government’s policy dur<strong>in</strong>g <strong>the</strong> 7 th and 8 th National Economic and Social Development Plan(1992-1996 and 1997-2001) which attempted to restructure agricultural production systems* Deputy Director-General, Department of Agricultural Extension, M<strong>in</strong>istry of Agriculture and Cooperatives,Bangkok, Thailand.** Senior Subject Matter Specialist, Farm Management Group, Agri-bus<strong>in</strong>ess Promotion Division, Departmentof Agricultural Extension, M<strong>in</strong>istry of Agriculture and Cooperatives, Bangkok, Thailand.130
