HRDI is continually developing, evaluating and improving the performance of corporate functions, which supports HRDI’s core and mission, e.g. information technology, organizational administration, human resource development and training workshops for Hill Tribes and staff to ensure HRDI can effectively achieve its vision and objectives. There are many development fields with which that HRDI is dealing. After more than fifty years these activities go beyond the opium elimination to development programs for poverty eradication, sustainable management of environmental resources, peace, and many social welfare projects.
