Question: Both written by George Harrison "Bangla Desh" and "Deep Blue" were songs intended to raise awareness for what?

Context paragraphs:
Azurite: Azurite is a soft, deep blue copper mineral produced by weathering of copper ore deposits.  It is also known as Chessylite after the type locality at Chessy-les-Mines near Lyon, France.  The mineral, a carbonate, has been known since ancient times, and was mentioned in Pliny the Elder's Natural History under the Greek name "kuanos" (κυανός: "deep blue," root of English "cyan") and the Latin name "caeruleum".  The blue of azurite is exceptionally deep and clear, and for that reason the mineral has tended to be associated since antiquity with the deep blue color of low-humidity desert and winter skies.  The modern English name of the mineral reflects this association, since both "azurite" and "azure" are derived via Arabic from the Persian "lazhward" (لاژورد), an area known for its deposits of another deep blue stone, lapis lazuli ("stone of azure").

Deep Blue (song): "Deep Blue" is a song by English musician George Harrison, released as the B-side to his 1971 charity single "Bangla Desh".  Harrison wrote the song in 1970, midway through the recording sessions for "All Things Must Pass", and recorded it in Los Angeles the following year while organising the Concert for Bangladesh.  The composition was inspired by the deteriorating condition of his mother, Louise, before she succumbed to cancer in July 1970, and by Harrison's feelings of helplessness as he visited her in hospital in the north of England.  Given the subject matter of his lyrics, "Deep Blue" also served to convey the suffering endured by the millions of refugees from war-torn Bangladesh in 1971, as sickness and disease became widespread among their makeshift camps in northern India.

The Concert for Bangladesh: The Concert for Bangladesh (or Bangla Desh, as the country was originally spelled) was the collective name for two benefit concerts organised by former Beatles lead guitarist George Harrison and Indian sitar master Ravi Shankar.  The concerts were held at 2:30 and 8:00 pm on Sunday, 1 August 1971, at Madison Square Garden in New York City.  The shows were organised to raise international awareness and fund relief efforts for refugees from East Pakistan (now Bangladesh), following the Bangladesh Liberation War-related genocide.  The concerts were followed by a bestselling live album, a boxed three-record set, and Apple Films' concert documentary, which opened in cinemas in the spring of 1972.

Bangla Desh (song): "Bangla Desh" is a song by English musician George Harrison.  It was released as a non-album single in July 1971, to raise awareness for the millions of refugees from the country formerly known as East Pakistan, following the 1970 Bhola cyclone and the outbreak of the Bangladesh Liberation War.  Harrison's inspiration for the song came from his friend Ravi Shankar, a Bengali musician, who approached Harrison for help in trying to alleviate the suffering.  "Bangla Desh" has been described as "one of the most cogent social statements in music history" and helped gain international support for Bangladeshi independence by establishing the name of the fledgling nation around the world.  In 2005, United Nations Secretary-General Kofi Annan identified the song's success in personalising the Bangladesh crisis, through its emotive description of Shankar's request for help.

Bangla Desh – A Voice of a New Nation: Bangla Desh – A Voice of a New Nation was an anthology of poems published in 1971, when the people of the-then East Pakistan, now Bangladesh, was fighting the war of independence against the occupation army of West Pakistan.  It was a collection of seventy poems by fifty poets, all translated from Bengali into English by Pritish Nandy.  It was stated in the credit page that 'The translator's royalty from the sale of this book will be donated to the Bangla Desh Assistance Fund'.  Notably Bangladesh emerged as an independent state on 16 December 1971.

Far East Man: "Far East Man" is a song written by English musicians George Harrison and Ronnie Wood, each of whom released a recording of the song in 1974.  Wood's version appeared on "I've Got My Own Album to Do", his debut solo album, and Harrison's on "Dark Horse".  Their only official songwriting collaboration, "Far East Man" is an affirmation of friendship in the face of life's obstacles and musically reflects the two guitarists' adoption of the soul genre.  Written mostly by Harrison, the composition has been interpreted as a restatement of the humanitarian message expressed in his 1971 single "Bangla Desh", and a tribute to Indian musician Ravi Shankar.

Orange ribbon: The orange ribbon is a symbol adopted for a very wide variety of uses in different places.  It is currently being used in the #savecedric campaign to promote the continued unification of the "westside" region of a business in Northern Indiana.  Many efforts are being made by local supporters to raise awareness of this cause.  It was more recently used worldwide to promote awareness of self-harm on March 1, 2012.  March 1 is designated as Self-injury Awareness Day (SIAD) around the world.  On this day, some people choose to be more open about their own self-harm, and awareness organisations make special efforts to raise awareness about self-harm.  Some people wear an orange awareness ribbon or wristband to encourage awareness of self-harm.

The Concert for Bangladesh (album): The Concert for Bangladesh – originally titled The Concert for Bangla Desh – is a live triple album by George Harrison and celebrity friends, released on Apple Records in December 1971 in America and January 1972 in Britain.  The album followed the two concerts of the same name, held on 1 August 1971 at New York's Madison Square Garden, featuring Harrison, Bob Dylan, Ravi Shankar, Ali Akbar Khan, Ringo Starr, Billy Preston, Leon Russell and Eric Clapton.  The shows were a pioneering charity event, in aid of the homeless Bengali refugees of the Bangladesh Liberation War, and set the model for future multi-artist rock benefits such as Live Aid (1985) and the Concert for New York City (2001).

Joi Bangla: Joi Bangla is an EP by Indian sitar virtuoso Ravi Shankar, issued in August 1971 on Apple Records.  The recording was produced by George Harrison and its release marked the first in a series of occasional collaborations between the two musicians that lasted until the "Chants of India" album in 1997.  Shankar recorded the EP in Los Angeles, to help raise international awareness of the plight faced by refugees of the Bangladesh Liberation War, in advance of his and Harrison's Concert for Bangladesh shows at Madison Square Garden, New York.  Side one of the disc consists of two vocal compositions sung in Bengali, of which the title track was a message of unity to the newly independent nation, formerly known as East Pakistan.  The third selection is a duet by Shankar and sarodya Ali Akbar Khan, supported by Alla Rakha on tabla, a performance that presaged their opening set at the Concert for Bangladesh.

L'Desh Fresh: L'Desh Fresh is a fictitious bottled water company created by Water.org to raise awareness about unsanitary drinking water in developing nations.
