The CGIAR Research Program on Forests, Trees and Agroforestry (FTA), led by the Center for International Forestry Research (CIFOR), focuses on the sustainable management of forests, trees and agroforestry systems. Strengthening the capacity of forestry, trees and agroforestry research, policy and implementing institutions and their staff is critical to FTA’s mission and is embedded in its work. Capacity development is a long-term process whereby individuals, organizations and their networks improve their systems, resources, skills and knowledge. This becomes reflected in their capacity to perform functions and solve problems to better address national and sub-national development objectives. Capacity development enables research and development organizations, individuals, and their networks to achieve impact.This capacity needs assessment was conducted in 2018 to identify the capacity needs of World Agroforestry (ICRAF) and CIFOR to achieve the research objectives and targets specified in the FTA II proposal 2017–2021, including the amended FP2 proposal. The capacity needs assessment focused on four key areas for analysis: partnerships, networking, resource mobilization and human resource capacities. The analysis and recommendations contained within this document result from data collated from more than 70 interviews conducted with flagship and cluster leaders and key actors within the FTA II management teams and partner organizations.
