Literal
Obstetricians [subject-が] keep-decreasing, obstetric-care [subject-が] crisis [into-に] is-falling-into.
A news-analytical sentence on a Japanese healthcare issue. 減り続ける is a productive compound: 減る ('decrease') + 続ける ('continue') = 'continue decreasing,' 'keep on shrinking.' The ~続ける auxiliary attaches to any verb stem to mean 'keep doing X.' 陥る (おちいる) is a slightly literary verb for 'to fall into, slip into (a negative state)' — usually used with abstract negatives like 危機 (crisis), 混乱 (confusion), 苦境 (predicament). 危機に陥る is a fixed collocation for 'fall into crisis.' Together the sentence depicts a cascading problem in two strokes.
