We all work together for the progress of cassava.CIAT work team ❖ Vital starting point in the activities.❖ Defined roles and valuable experience.❖ Fluid and constant communication.❖ Resilient and adaptable teamFarmersThey are a crucial source of expertise for us! Real insights into your needs and challenges. Potential trial establishment partners.We work in constant contact and to strengthen and expand our network with farmers, industries and cassava associates. Field teamThe goal is to maintain a united and trained group. Limitations to understand trials. Total compromise and proactivity. Vital experience in cassava and the regions where we work. They are the most important people in the breeding program in the Humid Caribbean. Fields for long terms We invest a significant effort in the search for new land and its adaptation.It directly affects our planting and harvesting calendar. A minimum of 1.5 is required for a planting and harvesting season. There must be a strong interest of the owners or partners in the cultivation of cassava. They must be sincere, proactive and friendly people. 5 years is our goalFields for long terms CIAT -Technification and equipment.-Experience and support. -Strategic connections (industry, markets and state). -Use of roots and plant material from trials.Owners or Institutions -Stability to work with planning.-Team training. -Special projects (F1). -Knowledge of the land. Challenges of working on the north coast➢ Environmental conditions.➢ Technician machinery.➢ Trials with poor germination.➢ Regional security.➢ Obtaining land to set up trials.➢ Vehicle access and routes. Improvements required in the sector➢ Increase productivity. ➢ Tenification of cassava production (mixes material, bad weed and pest).➢ Tolerance to diseases. ➢ Access to special markets. ➢ Increased competitiveness.➢ AssociativityImprovements for 2022 in Humid Increased the number of locations with respect to 2021.Improved space utilization for the coming year.New relationships were created with industry, academia and farmers. Implementation of new technologies. New personal learning in 2022• Management of several locations at the same time.• Planning.• Contact with the sector.• Relations with strategic allies. • Cassava equipment and data analysis.• knowledge in breeding and Materialspersonal learning for 2023• Academic Growth. • Growth in Project Management.• Improving data management and analysis. • Breeding skills• Building a solid and valuable network of contacts in the cultivation of cassava as my former advisor on the coast. Personal learning for 2023• Better use of space• Continue to decrease the number and size of trials• Next step for lead workers at each location. Personal learning for 2023• Better use of space• Continue to decrease the number and size of trials• Next step for lead workers at each location. Thank you very much!
