ASSESSMENT OF THE IMPACT OF A FARMING SYSTEMS-BASED TECHNOLOGY SITE IN SRI LANKA N. F. C. Ranaweera, P. A. Samaratun 3, J. M. K. P. Jayasinghe, and G. K. Renuka B Sri Lanka has been actively involved in the development of new technologies within the perspective of farming systems over the last 15 yr. Increasingly, questions have been asked as to the impact of such technologies to the farming community. Previous impact studies concentrated primarily on the adoption levels of the technologies and less in terms of actual impact. This study critically examines the impact of a new technology at a particular site in Sri Lanka. Using production function techn~ques, the study concludes that there were structural changes in the production process and in the personal incomes of farmers. However, there were no significant changes observed in capital accumulation, nutritional status, and expenditure patterns between the adopters and nonadopters of the new technology. Agriculture in Sri Lanka faces problems of increased consumer demand for basic foods, high unemployn~ent in the rural sector, and diminished land resources. Strategies were developed to address these problems by increasing the intensity of cultivation and diversifying the use of limited farm resources. Within this framework, a strategy for crop diversification combined with intensification of resource use was considered the key to stronger agricultural growth. FARMING SYSTEMS RESEARCH IN SRI LANKA These problems in agriculture required the developnlent of suitable component technologies (e.g., varieties with appropriate duration, crop combinations, and crop sequences) that were not only technically feasible but socially acceptable and econon~ically tenable. Rice and other field crops (OFC) are produced in Sri Lanka on small-scale family farms on which interactions between farm production, off-farm and nonfarm activities, and household consumption are highly significant. Initial studies began in 1976 at Walagambahuwa (a minor tank-based cropping system in the low-country dry zone) and Katupotha (in the low-country intermediate zone). Subsequently, the Department of Agricult~lre commenced farming systems research (FSR) programs in other locations under the purview of six regional agricultural research stations (Table 1). Details of these findings are described by Fernando (1979), Upasena (19Sla,b), and Sikurajapathy (1986).

Impact studies A number of studies documented the adoption of the new technologies, but few concentrated on their impact. Ranaweera and Siripala (1980) and Ranaweera (1983) studied the impact of new cropping systems technology under minor-tank irrigation conditions and concluded that the impact had been primarily in terms of component technologies--bztter crop management and use of improved varieties. To e\.aluate the impact of FSR on real incorne or on household expenditure patterns, nutrition, education, accumulation of household and agricultural capital items, or other assets, a study was initiated in 1987 at two FSR sites--Uva Paranagarna and Katupotha. OBJECTIVES The spzcific objectives of the study were to examine the adoption of new technical practices by farmers and estimate the relative efficiency of resources used under traditional and new technologies; to study the impact of technology adoption on the structure of crop-production functions, factor inco~nes, and personal incomes; and to examine the impact of the technology on nonq~~antifiablt: benefits such as better standards of nutrition. STUDY SITE The Uva Valley, represented by the Uva-Paranagama FSR site, has 25,000 smallscale vegetable farmers ~ ~llo operate, on average, on less than 0.5 ha and are responsible for nearly 60% of the total vegetable and potato production of the country (Agricultural Implementation Programn~e 1990). Of thz 6,600 ha of 1o:vland ricefields in the region, about 6,400 ha are cultivated nith rice during the maha (January-May) season. A major portion (50%) of the lowland area is used for a second crop of vegetables and potatoes planted immediately after the rice crop. The balance of the land has problems with drainage or irrigation. A second crop of rice is usually grown if the problem is drainage; if poor irrigation is the problem, the field is left fallow. The third crop for the year in the lowlands coincides with the heavy rains and cold ten~perat~~res of October- December. This is the only period when nonirrigated ~~pland areas can be cultivated with a seasonal cash crop. The FSR site at Uva Paranagama represents the complex physical environment of the region.
