Box 1346 Ann Arbor, Ml 48106- 1346 ABSTRACT In short, the study proposes that farming in a marginal rain-fed environment such as that of the Northeast Region of Thailand presents special problems for the intensification of production, and that government policies should take account of these problems. The thesis is based on fieldwork conducted in ctwo villages in the province of Mahasarakham, Northeastern Thailand, during the period September 1982 to June 1983. The villages were both farming communities in which households grew rain-fed wet-rice to meet their subsistence requirements, and upland cash crops (principally cassava) to supplement their income. A detailed questionnaire was conducted among approximately a fifth of the population. The work involves an analysis of farmers1 practices vis a vis rice and upland cropping and contrasts them with the government recommendations. There were significant disparities between the two and these have been explained from the perspective of the farmer, rather than that of the extension office. The outcome is that many government initiatives are shown to be less than relevant to the position in which the farmer finds himself. This fact - that the government recommendations are often irrelevant to the inhabitants - is then expanded upon to reveal some of the problems of intensifying agricultural production in a marginal environment where the risks are great. The strategy that the farmers adopted appeared to consist of two contrasting, although not contradictory,- elements: firstly, a great specificity of response to varying edaphic and topographic conditions; and secondly, an emphasis on flexibility of response to the variable climate. Both elements combine to stabilise production or minimise risk. The resulting limited opportunities for investment in agriculture forced farmers to look for a large proportion of their cash income outside rice and upland crop cultivation. This was accentuated by the ever-increasing pressure on farmers to have a greater disposable income, and emphasises the importance of diversifying the farm economy and presenting farmers with opportunities outside agriculture. 3 k CONTENTS Page List of Tables^ Maps/ Figures/ Graphs and 5 Appendices Acknowledgements 16 Glossary of Thai Terms 17 Conversion Table 18 Abbreviations 19 Chapter One Introduction/ Theory and Aims 22 Chapter Two 'The Northeast Problem' 62 Chapter Three The Khorat Region and the 121 Province of Mahasarakham: Their Physical Characteristics Chapter Four The Villages of Baan Noon Tae 155 and Baan Tha Song Korn Section I The Strategy of Cultivation in the Study Villages Chapter Five Rice Cultivation in Noon Tae 201 and Tha Song Korn Chapter Six Upland Crop Cultivation in Noon 280 Tae and Tha Song Korn Chapter Seven Cooperative Membership in Noon 344 Tae and Tha Song Korn Section II Alternative Strategies Chapter Eight Alternative Sources of Income 385 Chapter Nine An Alternative Development 413 Project: 'CBIRD' Chapter Ten Synthesis 456 Appendices 476 Bibliography 493 5 List of Tables Chapter Two 2.1 Population, Land Area and Gross Regional Product of Thailand, by Region. 2.2 Land use in the Northeast (1980). 2.3 Population and Contreceptive Use in Thailand and the Northeastern Reion. 2.4 Land Holdings by Tenure and by Region. 2.5 Forested Area of Thailand as Percentage of Total Land Area. 2.6 Distribution of the Poor Population, by Region and by Area, 1962/3 & 1975/6 (% of total poor population). 2.7 Levels of Malnutrition in Thailand. 2.8 Change in the Northeastern Region’s share of the Gross Domestic Product: 1960-1969. 2.9 Tambon Development Programme Funding, per Capita, by Region. 2.10 Estimates of Water Storage Potential and Irrigable Land in the Northeast. 2.11 Average Rates of Fertiliser Application and Yields in Thailand and Other Selected Asian Countries. 2.12 Area Planted to Kenaf in the Northeast: 1950-1980. 2.13 Exports and Imports of Jute and Kenaf: 1975-1980. 2.14 Area Planted and Production of Cassava in the Northeastern Region. 2.15 Kenaf: Five-year Moving Average, 1962-1971 (Northeastern Region). 2.16 Importance of Various Upland Crops in the Northeast Region of Thailand (crop year 1980/1981). 2.17 Interest Rates on Agricultural Credit in the Northeast: Formal and Informal Sources. 6 (List of tables con't) Chapter Three 3.1 Maximum, Minimum and Standard deviation of Monthly Rainfall in Mahasarakham, 1971-1982. 3.2 Possible Rainfed Farming Periods Based on Effective Rainfall: Changwat Mahasarakham. 3.3 Land Suitability and Land Use in the Northeast. 3.4 The Extent of Erosion in the Northeast and in Mahasarakham Province. 3.5 The Soils of Mahasarakham. 3.6a Characteristics of the Soil Series in the Vicinity of Baan Noon Tae and Baan Tha Song Korn. 3.6b Soil Analysis: Changwat Mahasarakham. 3.7 Influence of Soil Organic Matter on Soil Properties.
