[3][13] He has photographed inside psychiatric hospitals in El Borda in Buenos Aires, Argentina and Conxo (Santiago de Compostela, Galicia).

He walked for 30 days, from Roncesvalles, the Camino de Santiago[2] on assignment for a Galician newspaper, sending chronicles by fax and letters together with the rolls of film.

[15] He proposed that other Galician and international photographers join the project, thus creating a diversity of fourteen[16] different views of the old pilgrimage road, each unique, in which each author traveled a portion of the Camino for a week.

In the second decade of the 21st century, due to the crisis in Galicia and Spain, a second wave of Galician emigration began, mainly to countries of northern Europe (Germany and England), primarily educated young people.

In 1989 he began the long term documentary Galegos na Diáspora, travelling around the world by bus with other emigrants and documenting the fall of the Berlin wall and Galicians living there.

[19] In 2009, he travelled around the US, from New York to Washington DC, Boston, Miami, Texas, Houston, Kansas, San Francisco, Chicago, Lincoln, and flying to Panama, Chile and Argentina, ending the project to publish Galegos na Diáspora 1989-2009.

[20] In 2009 he filmed "Fuga de Cerebros", a documentary for TVG about Galician scientists living in the Diaspora in Stockholm (Sweden), Paris (France), Cologne (Germany) and Alabama (US), but it was not broadcast.

Between 2007 and 2008 in co-production with TVG, Signe Raikstina, and journalist Arturo Lezcano, they filmed "O rei galego de África" in Namibia.

[23] Alvarez gave presentations[24][25] at the Library of Congress in Washington, DC, in 2009 and at the City University of New York (CUNY) about the project Galegos na Diáspora.

[32] Álvarez produced four broadcast documentaries from an ethnographic and anthropological perspective of the Galician diaspora in Africa, Venezuela and Russia based in the book Galegos na Diáspora 1989-2009.
