decisionmakers at the Federal, regional, State, tribal, and local levels of government;
(B)
the private sector; and

(4)
coordinate, and integrate, through interagency agreements as practicable, Federal research and monitoring in support of a drought early warning information system;

utilize existing forecasting and assessment programs and partnerships, including forecast communication coordinators and cooperative institutes, and improvements in seasonal precipitation and temperature, subseasonal precipitation and temperature, and low flow water prediction; and
(6)
continue ongoing research and monitoring activities related to drought, including research activities relating to the prediction, length, severity, and impacts of drought and the role of extreme weather events and climate variability in drought.
(c)

Partnerships

The National Integrated Drought Information System may—
(1)
engage with the private sector to improve drought monitoring, forecast, and communication if the Under Secretary determines the partnership is appropriate, cost-effective, and beneficial to the public and decisionmakers described in subsection (b)(2)(A);
(2)
facilitate the development of 1 or more academic cooperative partnerships to assist with National Integrated Drought Information System functions; and
(3)
utilize and support, as appropriate, monitoring by citizen scientists, including by developing best practices to facilitate maximum data integration.
