From cassavas to papayas, the International Center for Tropical Agriculture is concerned with the viability of crops across the world. Specifically, their stated mission is "to reduce hunger and poverty in the tropics through collaborative research that improves agricultural productivity and natural resource management." From their homepage, visitors can read press releases and statements about their most recent findings, and also look over timely documents such as "Integrated Soil Fertility Management in the Tropics" as well as their annual report. The "Research" section is another good place to wander around, as it contains reports on two of their primary areas of interest: agrobiodiversity and the interaction between people and agroecosystems. Finally, it is worth noting that many of the materials here are also available in Spanish.
