MANILA, Philippines – President Ferdinand Marcos Jr. ended his SONA last year with a bang: the crackdown on corruption surrounding flood control projects.

What followed were investigations into corruption in the highest echelons of government, the uncovering of scandalous wealth and contractor ties, public condemnation, and the death of a former Department of Public Works and Highways (DPWH) official.

That all started with an environmental issue: Infrastructure — dikes, pumping stations, retaining walls — that have failed to keep communities safe from floods. Worse, many were even ghost projects.
