After the 1975 occupation of Western Sahara by Morocco, the Catholic population of the prefecture went down from 22515 to 368, and the prefecture was renamed as the Prefecture of Western Sahara with just 2 parishes and 3 religious people. Erviti then spent 19 years working towards the betterment of the refugees in the Sahrawi refugee camps while cooperating with the United Nations Mission for the Referendum in Western Sahara (MINURSO). Pope John Paul II accepted his resignation in 1994 due to reasons of old age, and he retired to the provincial house of his order in Madrid.
