SUMMARY:

Coffee (Coffea arabica L.) is an agricultural crop that is treated prominently on the global stage, classified as one of the most traded commodities, being the raw material for the second most consumed beverage in the world, after water. Such is its importance worldwide that data from the International Coffee Organization indicate that production in the world, between October 2021 and September 2022, was 170.83 million bags. These figures reveal the economic impact of coffee cultivation and demonstrate that its consumption greatly affects the global economic sector. In this sense, an ancestral coffee emerges that dates back to the arrival of the first coffee plants in Brazil, currently these plants produce coffee on a small scale, as is the case in the municipality of Irituia. The pioneering role of the state of Pará in coffee production in the 19th century promoted a race that would disseminate coffee plants in the municipalities of the state. This spread made Pará the first exporter, sending coffee from Belém to Portugal in 1732. The coffee rush took place in locations close to rivers and, in this context, the Capim and Guamá rivers were important for the propagation of the fruit of the Rubiaceae botanical family in the areas that include the municipalities of Irituia, São Domingos do Capim, Ourém, Capitão Poço, Mãe do Rio and São Miguel do Guamá, which currently have agricultural characteristics. The decline in coffee production in the region was caused by the difficulty of adapting to the climate and the rubber cycle, which allows us to infer that the remaining coffee varieties in the regions of the state may exhibit characteristics that are tolerant to the hot climate, such as the species Coffea canephora and C. liberica, and there are no narratives about the production of Liberian coffee in the national scenario. In this context, it is understood that there is a need to characterize the coffees produced in agroforestry systems in these municipalities, as they contribute to the maintenance of the forest and recognition of this ancestral coffee that resists time, highlighting the possibility of an innovative product that can add value to the system in which it is being cultivated, in addition to demonstrating adaptive characteristics to the climate, important in the context of climate change and deforestation experienced in the Amazon. In view of this, the objective of the work is to characterize the species of ancestral coffees cultivated in agroforestry systems in the municipalities of the Guamá microregion and their relationships with the environment. The study's method is to collect samples of coffee plants for the preparation of exsiccates in the IAN herbarium to characterize the plants taxonomically. Therefore, soil collections and height and diameter measurements are being made through inventories in the agroforestry areas where ancestral coffee is found.
