CENTER FOR TROPICAL AGRICULTURE The Center for Tropical Agriculture, within the Institute of Food and Agricultural Sciences, seeks to stimulate interest in research and curriculum related to the tropical environment and its development. GRADUATE PROGRAM.-An interdisciplinary minor in tropical agriculture may be planned at both the master's and doctoral levels by students majoring in agriculture, forestry, and other fields where knowledge of the tropics is relevant. The minor may include courses treating characteristics of the tropics: its soils, water, vegetation, climate, agricultural production, and the language and culture of tropical countries. RESEARCH.-The Center provides research grants to faculty members and their graduate students and assists in the coordination of interdisciplinary research funded elsewhere. Development assistance contracts in agriculture and related fields frequently have research components. STUDENT SUPPORT.-Students within the College of Agriculture and the School of Forest Resources and Conservation pursuing a minor in tropical agriculture are eligible for assistantships awarded by the Center through academic departments. OTHER ACTIVITIES.-The Center seeks a broad dissemination of knowledge about tropical agriculture through the sponsoring of conferences and seminars featuring leading authorities on the tropics; publication of books, monographs, and proceedings; and through acquisition of materials for the library and the data bank. URBAN STUDIES BUREAU The Urban Studies Bureau attempts to stimulate and coordinate interdis- ciplinary graduate training, research, and service activities related to urban affairs. The Bureau cooperates with departments in administering an Urban Studies Certificate Program. This program provides training for graduate students preparing for careers which require a broad understanding of urban areas and problems.
