The INAI is responsible for administrating the National Registry of Indigenous Communities (Renaci), which keeps track of Argentina's Indigenous communities and their legal rights to their ancestral lands. Toward the end of 2018, some 1,653 communities had been registered, of which 1,456 held legal ownership over various territories. In addition, the INAI must carry out specific programmes oriented toward the development of idnigenous communities and policies to improve their quality of life. These include environmental and housing programmes, sustainable food production programmes, and various initiatives to safekeep and rescue endangered cultural elements such as
language. In particular, the INAI is concerned with maintaining bilingual and inter-cultural education among Indigenous communities. ==Criticism and shortcomings==
