can also project the supply and price effects of changes in farming systems to determine impacts on farm in- comes, costs of living, the nutritional status of various demographic groups and other important welfare in- dicators. Economists should coordinate their efforts with those of animal and crop scientists. SM research should emphasize farm systems analysis of crop and livestock enterprises, considered both separately and jointly. Agricultural economists and farm managers have much to contribute to the analysis of farming systems. Economics should be incorporated into the analyses of alternative farming systems, but not to the exclusion of contributions from agronomists and animal scientists (Johnson, et al., 1961; Johnson, 1982). The number of small, mostly part-time farms and the number of large farms in the United States are increas- ing, while the number of medium-sized farms is decreas- ing. FSR is particularly needed for both small, part-time and large-scale farms. In the less-developed world, FSR has concentrated on technical advance with a neglect of household aspects. FSR has not been as holistic and integrative as the farm and home development research and extension programs of the 1950s and '60s (Johnson, 1982). FSR for small-scale and part-time agricultural enterprises in the United States should be based on an integrated view of both production and the household. The role of women on both small and large farms has not been adequately assessed and is important in setting research priorities. Integrated pest management and regenerative agricultural production systems should be addressed. Like farm management in its earlier days, FSR today should be multidisciplinary and multidepart- mental in colleges of agriculture. The household aspects should be considered as they were in the 1950s. Land will be scarcer in the next 50 years. It will be necessary to utilize soils not now farmed and to farm more intensively the land now in use. It will be necessary to invest additional capital in soils to make them into productive lands. Farming systems analysis should em- phasize timing of capital investments in soils to make them productive. Systems analyses of livestock/crop pro- duction systems are needed, with emphasis on how to harvest improved high-yielding forages from rough, fragile soils without the soil and forage losses associated with heavy grazing and trampling by animals. As land use intensifies, systems analyses of multicropping and intercropping technologies will become crucial. Farm- ing systems analysis must cross the traditional depart- ments of agronomy, agricultural economics, horti- culture, animal science and rural sociology. Research on firms that market, process and distribute farm products is important. Agricultural economists often pursue such interests under the label of industrial organization (conduct, structure and performance) research. New technologies may change the structure of production, marketing, processing and distribution. Reciprocally, sought-after changes in structure may determine the technology created. Research efforts should investigate the creation of technologies for obtaining power to concentrate the control of farming and agribusiness in fewer hands. Some technologies hav- ing to do with price and production uncertainties of marketing and processing through distribution firms may be reduced. There is a need for analyses of farm production and marketing subsystems as parts of larger subsectorial systems. Equity and equality issues are raised with increasing frequency as technological advances preferentially favor large-scale or small-scale farms, males or females, and various demographic groups. Equity and equality are not the same. An equitable distribution of income or rights and privileges is a justified but not necessarily equal one. The International Association of Agricultural Economists devoted its last 10-day triennial meeting, held in Jakarta in 1982, to "Growth and Equity" and made considerable progress in understanding the theoretical and empirical relationships among growth, equity and equality. Some contend that it is equitable or justifiable to generate technologies favoring large-scale farms because they are more productive and make a higher proportion of their output available to the rest of society. Others argue that more equality between small- and large-scale farms would be equitable. Some variations in total net incomes of farm and non-farm laborers are justified by differences in resources con- tributed and effort put forth and can therefore be regarded as equitable. Equity and equality also relate to rates of return per unit of labor, land, capital or energy, such as marginal earnings per day of labor and returns to marginal investments in capital and land and use of energy. The attainment of equality in returns at the margin does not guarantee equality in total net returns. Equality in returns at the margin seems easier to justify as equitable than equality in total net returns. Issues of equity and equality within agriculture and between the agricultural and non-agricultural sectors now receive less attention than formerly in the ARE, despite the increasing criticism of the ARE and its research institutions, science policies, programs and priorities. Technological advances and public infrastructures sup- port productive agriculture. SM research should con- tinue on how technological advances and changes in resource availability will alter marketing and informa- tion systems, production sites and the institutions that control agriculture. Requirements for public roads, transportation, irrigation and drainage, and regulatory activities will be affected. The private physical infrastructures that support
