Monitoring and Early WarningMonitoring and early warning committeeA. Establish drought management areasB. Inventory data quantity, quality from current observation networksC. Determine data needs of primary usersD. Develop a drought monitoring systemF. Develop or modify current data and information delivery systems2. Risk and Impact AssessmentRisk and impact assessment CommitteeTask 1: Conduct a Drought Impact AssessmentTask 2: Rank the Most Pressing ImpactsTask 3: Conduct a Vulnerability AssessmentTask 4. Identify Risk Management Options (actions/activities to do for eliminating or reducing risk)Task 4.
