The Gaia Student Blog has some interesting grants including grants on geospatial health studies, USAID, USDA, and UNDP funding mechanisms for students and faculty. There are also two grants for Healthy Kids projects (1st and 2nd). There is also the Fulbright Specialists Program (Council for International Exchange of Scholars). The above international USDA program is similar to the Fulbright program.
If faculty can manage some sabbatical time, they might consider an AAAS (1 year) or USNRC (6 months) policy fellowship in Washington DC with agencies such as the USEPA, FDA, USDA, USAID, USDHS and others. These are effective methods to get an idea of nationally important research and really step up your LLU research program.
