Roots and tubers

Tropical starchy root crops and tubers – cassava, sweet potato, yam and dasheen –, or "RTs", play a vital role in food security for populations in tropical zones, against a backdrop of population growth and rapid urbanization, particularly in Africa. ºÚÁÏÍø911 has substantial expertise in these value chains, ranging from genomics to postharvest technology through varietal improvement, plant health, cropping systems and value chain economics. ºÚÁÏÍø911's approach is multidisciplinary and often innovative.
