Photography by indigenous peoples of the Americas: Photography by indigenous peoples of the Americas is an art form that began in the late 19th century and has expanded in the 21st century, including digital photography, underwater photography, and a wide range of alternative processes.  Indigenous peoples of the Americas have used photography as a means of expressing their lives and communities from their own perspectives.  Native photography stands in contrast to the ubiquitous photography of indigenous peoples by non-natives, which has often been criticized as being staged, exoticized, and romanticized.

Spanish Argentines: Spanish settlement in Argentina, that is the arrival of Spanish emigrants in Argentina, took place firstly in the period before Argentina's independence from Spain, and again in large numbers during the late 19th and early 20th centuries.  Between the 15th and 19th centuries, the Spanish Empire was the sole colonial power in the territories that became Argentina after the 1816 Argentine declaration of independence.  Thus, before 1850, the vast majority of European settlers in Argentina were from Spain, and they carried the Spanish colonial administration, including religious affairs, government, and commercial business.  A substantial Spanish-descended Criollo population gradually built up in the new cities, while some mixed with the indigenous populations ("Mestizos"), with the Black slave population ("Mulattoes"), or with other European immigrants.

Indigenous peoples in Argentina: Argentina has 35 indigenous groups or Argentine Amerindians or Native Argentines, according to the Complementary Survey of the Indigenous Peoples of 2004, in the first attempt by the government in more than 100 years to recognize and classify the population according to ethnicity.  In the survey, based on self-identification or self-ascription, around 600,000 Argentines declared to be Amerindian or first-generation descendants of Amerindians, that is, 1.49% of the population.  The most populous of these were the Aonikenk, Kolla, Qom, Wichí, Diaguita, Mocoví, Huarpe peoples, Mapuche and Guarani In the 2010 census , 955,032 Argentines declared to be Amerindian or first-generation descendants of Amerindians, that is, 2.38% of the population.

Famines in India resulted in more than 60 million deaths over the course of the 18th, 19th, and early 20th centuries.  The last major famine was the Bengal famine of 1943.  A famine occurred in the state of Bihar in December 1966 on a much smaller scale and in which "Happily, aid was at hand and there were relatively fewer deaths".  The drought of Maharashtra in 1970–1973 is often cited as an example in which successful famine prevention processes were employed.  Famines in British India were severe enough to have a substantial impact on the long term population growth of the country in the 19th and early 20th centuries.
