Assessment of the impact of a farming-systems based technology site in Sri Lanka--N. F. C. Ranaweera, P. A. Samaratunga, J. M. K. P. Jayasinghe, and G. K. Renuka Impact assessment of farming systems research and development at the farm level: the rice-watermelon cropping system in Pangil, Laguna--V. T. Villancio, C. H. Manalo, M. L. Rebulanan, A. A. Arisgado, F. L. Matienzo, and N. F. C. Ranaweera Discussion and recommendations Participants Appendix: Acronyms
Welcome Address S. P. R. Weerasinghe1 This is a historic occasion. It is the first time a serious attempt has been made to evaluate the benefits accruing to technologies developed within a farming systems perspective. The presence of the Honorable R. M. Dharmadasa Banda, minister of Agricultural Development and Research, and his Secretary Mr. Dixon Nilaweera is a clear recognition of the importance attached to farming systems research. It is also a sign of appreciation to the efforts of scientists who contribute to the enhancement of agricultural productivity. Their research has a direct influence on the farmers who are the providers of food for our people. We are also privileged to have with us Dr. F. A. Bernardo, deputy director general of International Programs, International Rice Research Institute (IRRI), Dr. V. R. Carangal, coordinator of the Asian Farming Systems Research Network at IRRI, and Dr. John Graham and Dr. John Hardie from the International Development Research Centre (IDRC), which provided the necessary funds to make this farming system activity a reality. These studies would not have come to fruition were it not for the concerted effort and dedication of scientists from the national programs in South and Southeast Asia and from the international centers. This workshop is an opportunity to critically review the impact of farming systems research, to identify the advances and weaknesses, if any, and to make recommendations to enable national agriculturil research systems to reorient future programs. Within the context of diminishing arable land per capita and declining incomes from farming, especially from rice, this workshop is most timely. Although science and technology have made rapid advances in the past few decades, the application of new technologies in different farming situations has not had the desired effects on agricultural production and farm income. Asian farmers have adopted a farming system that has gone through a process of evolution. The goals of these farmers were subsistence for their families and preverltion of land degradation. Scientists have taken time to comprehend the aspirations of farmers, but questions must be asked about the ways that advances in science and technology have been translated to farmers. Farming systems research should not be confined to the development of technology packages to increase production. Trade, postharvest handling and processing, input supply and marketing, and many other factors are integral to farming systems research and can be adopted by farmers to increase the production potential of their resource base. These areas have not been included in systems research to the desired extent, but they are of paramount importance to the farmer. '~irector of Agriculture, Sri Lanka.
