The roots of malnutrition are found in economics, education, agriculture, and health. This multiple etiology requires that approaches to the problem engage many different institutions. These organizations can be viewed as constituting an International Nutrition Institutional Network. The functions of this system are collection and dissemination of information, provision of goods and services, financing, and coordination. Significant problems, however, have been identified in the performance of these functions. These are organizational: poor coordination, vague responsibility delineation, inadequate evaluation, people limitations, and internationalnational relationships. They are also political: policy vacuum, knowledge gaps, and priority conflicts. Unless these are rectified, the Network's effectiveness will remain severely limited.
