In 1990 and 1991 Álvarez documented the lives of Cubans during Periodo Especial en Tiempo de Paz, in a project titled Cuba, el ultimo bastion: la lucha de un pueblo.

He has photographed inside prisons, and the flow and settlement of immigrants to Europe and their human and living aspects.
He has photographed inside psychiatric hospitals in El Borda in Buenos Aires, Argentina and Conxo (Santiago de Compostela, Galicia).

He covered the Yugoslav wars (1991–1995) and published a book in 1994, called Reporteiro de guerra en Iugoslavia, about the fighting and aftermath of a war.
A new second edition in Spanish language is expected in winter 2020 Érase una vez en Europa.


In 1996 Álvarez traveled to Salvador de Bahia to document the consequences of poverty in Salvador de Bahía and the Sertão region: slavery and child labor of children working in the Sisal and pedreiras.
For four months Álvarez lived in Salvador and travelled to different places of the Bahia region documenting the judicial police, military police, street children and raids against the prostitution in the neighborhood of Beirú (Tancredo Neves) one of the most dangerous favelas of the capital.


In 1999, Alvarez began a personal project about the ancient pilgrimage to Santiago de Compostela.
He walked for 30 days, from Roncesvalles, the Camino de Santiago on assignment for a Galician newspaper, sending chronicles by fax and letters together with the rolls of film.
Later the same newspaper ordered him to travel the Portuguese Way from Lisbon only indicated from Oporto.

In 2006, based on these experiences, he was commissioned to publish a book and an exhibition of the Camino Francés from Roncesvalles.
He proposed that other Galician and international photographers join the project, thus creating a diversity of fourteen different views of the old pilgrimage road, each unique, in which each author traveled a portion of the Camino for a week.

With the different points of view, the photographers created a unique long term documentary photographic essay, exploring the ancient pilgrimage to Santiago de Compostela walked by millions of people around the world.
At the same time that the project was growing, the authors gave their own opinions on how to continue photographing, since in principle the organizers wanted something like beautiful postcards, which the photographers refused.
Several exhibitions were programmed around the world but the organizers changed the name of the project two times.
Four books were published from the project.

Participants in the project included Álvarez, Fernando Bellas, Tino Martínez, Javier Teniente, Xulio Villarino, Tino Viz, Cristina de Middle, Hana Jakrlova, Rita Newman, Chris Erlbeck, Tine Harden, Katja Lösönen, Eva Persson and Signe Raikstina.


Alvarez has documented the Galician diaspora, travelling to "a hundred cities" on five continents to inventory Galician immigration.

It is known as the Galician diaspora, the process of mass emigration of the Galician people to the Americas, which occurred during the last three decades of the 19th century until well into the middle of the 20th century.
In the first decade of the 20th century, the Galician Diaspora arrived by ship from Europe to Asia, and specifically Australia and New Zealand.
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.

In the next years 1990-91 he photographed in Canada, USA, Mexico, Cuba, Venezuela, Brazil, Argentina and Uruguay.
In 1992-93 he began the third part of the project in Jerusalem, Thailand, China, Japan, Australia and New Zealand.
In 2002 he travel around Africa from Cabo Verde to Senegal, Mauritania, Guinea Ecuatorial, Namibia, South Africa, Mozambique and Tanzania.

In 2006 he went to Russia with a team
