"Collaborative Research Support Programs (CRSPs) focus the capabilities of U.S. land grant universities to carry out the international food and agricultural research mandate of the U.S. Government. The CRSPs are funded by the U.S. Agency USAID for International Development (USAID), as well as collaborating organizations in the U.S. and collaborating countries. These collaborative agricultural research and agribusiness support programs benefit both the United States and developing/transitional countries with which the United States collaborates." - http://crsps.org/


Purdue University is involved with five CRSPs:



Purdue's College of Agriculture has been a partner with Virginia Tech, Management Entity, in the Integrated Pest Management Collaborative Research Support Program (IPM CRSP) for the past 15 years. Faculty from IPM CRSP the Departments of Agricultural Economics, Horticulture and Landscape Architecture, Entomology and Botany and Plant Pathology have been involved in IPM efforts in Latin America (Guatemala, Honduras, Ecuador), Bangladesh and West Africa (Mali, Niger, Burkina Faso, Senegal, Ghana, Benin, and Togo).

The current IPM CRSP project has seven regional theme programs and six global cross-cutting theme programs. Purdue faculty from Horticulture and Landscape Architecture (S. Weller) and Entomology (R. Foster) are involved in two regional programs: Those programs respectively are: Latin America and the Caribbean (LAC) Crops for Broad-based Growth and Perennial Production for Fragile Ecosystems and West Africa Regional Consortium of Integrated Pest Management Excellence.

Ecuador and Honduras are the main sites for the Latin America and Caribbean program. Host country institutions include: Honduras - FHIA (Honduran Agricultural Research Foundation) and Zamorano/PanAmerican School of Agriculture, and Ecuador Instituto Nacional Autonomo de Investigaciones Agropecuairas.

The West Africa Consortium includes Burkina Faso, Guinea, The Gambia, Senegal and Mali. Host country institutions working with the Consortium include: West Africa- AVRDC, INSAH, IITA; Senegal- ANCAR, DPV, ISRA, NARI, CERES Locustox; Mali- ETQCL, IER, IITA, OHVN; Burkina Faso - INERA; Guinea- IRAG.

INTSORMIL is a multi-University project sponsored by USAID to support research to increase the productivity of sorghum and millet. The regional focus has been on Sub Saharan Africa and Central America. Most INTSORMIL scientists are also engaged in the research programs of their own state so there are also domestic benefits. INTSORMIL scientists work in collaboration with the scientists of developing countries. Many of these national scientists were previously trained with INTSORMIL funds and INTSORMIL funds facilitate the continuation of partnerships begun with US scientists in the training process. The primary institutional connection in developing countries has been with the national agricultural research organizations. Recently, as there has been more stress on delivering technologies to farmers the institutional contacts have broadened to national extension agencies and to NGOs engaged in extension.

Breeding Sorghum for Improved Resistance to Striga and Drought in Africa At Purdue Gebisa Ejeta is a sorghum breeder involved with research on Striga and drought, who concentrates his activities on East Africa.

Product and Market Development for Sorghum and Pearl Millet in West Africa Bruce Hamaker is a food scientist. He works with other food scientists in West Africa and is helping millet food processors to develop their operations there.

Developing Sorghum with Improved Grain Quality, Agronomic Performance, and Resistance to Biotic and Abiotic Stresses
n etc.). Weed management is one of the most important considerations impacting sorghum production today. Weed infestations in the United States have been shown to reduce grain sorghum yields by up to 55% depending on time of infestation and weed pressure. Competition with weedy plant species also reduces grain quality, increases insect and disease pressures, and creates difficulty in harvest operations. In Africa, witchweed (Striga spp.) infestations are a growing menace for cereal crop producers across the continent. We have identified sorghum genotypes with tolerance to ALS and ACCase inhibiting herbicides over the last 5 years to address these problems.


Significant efforts are focused on transferring these technologies into sorghum varieties and hybrids adapted for production in developed and developing countries. One new and very promising Striga management technology developed in the program involves use of herbicide tolerance traits for managing this weed. Low-dose imazapyr or metsulfuron seed coatings applied to herbicide tolerant varieties have been shown to be highly effective in controlling Striga infestation in field and greenhouse trials. Locally-adapted varieties that couple host-plant resistance to Striga with herbicide seed treatments are being developed to identify the combination of traits that maximizes the efficacy of control. These efforts will facilitate the growth of the rapidly expanding markets for sorghum and millet, improve food and nutritional quality to enhance marketability and consumer health, increase the stability and yield of the crop, through use of genetic technologies, and contribute to effective partnerships with national and international agencies engaged in the improvement of sorghum.

Development of the Input and Product Markets in West Africa for Sorghum and Millet
John Sanders is an agricultural economist. His present focus is on extension of new technologies and marketing techniques to increase the profitability of the higher input levels recommended. In 2009 his Production-Marketing Project will have almost 1,800 ha in new sorghum and millet technologies on farmers' fields combined with improved marketing strategies by their farmers' associations to enable farmers to receive higher prices from value added techniques and improved market contacts. This activity is presently focused in the three countries of the Sahel, Niger, Mali, and Senegal.

Aquaculture CRSP

Improving Competitiveness of African Aquaculture Through Capacity Building, Improved Technology, and Management of Supply Chain and Natural Resources

Aquaculture CRSP


he project involves five separate studies at 3 US institutions and 3 African universities. The overall objective is to develop an agribusiness-focused aquaculture in sub-Saharan Africa through physical and human capacity development; new and better technology of fish production; growth of a whole chain of activities from farm to the consumer; better management of the natural resources; and increased profitability of fish production at the farm level. The 5 studies examine different stages in the whole chain of fish farming activities, beginning from management of natural resources, production and marketing of fish fingerlings and food fish to transportation and retail sales. Agribusiness-focused aquaculture will vitalize rural aquaculture entrepreneurship by providing capacity and opening up a larger market for rural aquaculture producers. Results from the investigations will help to achieve this goal for aquaculture in rural sub-Saharan Africa, and will provide additional employment and income generation that will create demand for other products, and thus support the growth of other rural economic activities.US Collaborating Institutions: Virginia Polytechnic Institute & State University and University of Arkansas at Pine Bluff (UAPB) Host Country Collaborating Institutions: Kwame Nkrumah University of Science & Technology, Ghana; Moi University, Kenya; and Sokoine University of Agriculture, Tanzania

Peanut CRSP

The goals of the Peanut CRSP are:

Peanut CRSP

1.Explore the effects of peanuts, their sensory properties (sweet versus salty) and components (oil, flour, butter, whole nut) on the glycemic response. There are theories that high glycemic index foods promote hunger and energy intake Peanut CRSP and evidence that peanuts may attenuate the glycemic response to such foods. Thus, they may help to curb appetite and energy intake through this mechanism. Three studies will be undertaken to explore this issue. If the component of peanuts responsible can be identified, this may open new opportunities for product development and dietary recommendations. This should expand markets and improve health

2. Explore the effects of nuts on energy regulatory systems. Specifically, the effects of peanuts on gut satiety peptide release, reward system activity (hedonics) and GI transit will be documented. Elucidation of the physiological responses to peanuts and peanut products will provide credibility to claims that they do not promote weight gain. This knowledge may open new opportunities for product development and dietary recommendations. This should expand markets and improve health.

3. Recommendations to increase peanut consumption may be made, but if they are not followed, there will be no impact on sales or health. Additional knowledge is needed on the acceptability of peanuts consumed on a chronic basis. Studies will examine shifts of acceptability under different conditions such as chronic inclusion of a single form versus varied forms of peanuts in the diet. Further, it is expected that such responses will be varied among individuals with different characteristics (e.g., prefer sweet versus savory foods, cognitive restrained, variety seeking). A better understanding of how different segments of the population may choose to include peanuts and peanut products in their diet and how to optimize chronic consumption should provide insights for better marketing and increased sales and health.
