The running fresh water of the Amazon River is a welcoming sound to the peoples of the indigenous resguardo (reserve) in Puerto Nariño, southern Colombia. This watercourse is the only access to the banks of rivers, lakes, flood plains and mainland areas that connect the 22 communities where the Tikuna, Cocama and Yagua peoples live.

To obtain food according to each season, the Tikuna, Cocama and Yagua peoples combine different practices, such as fishing, hunting and chagras farming, an ancestral, diversified productive system in which annual and perennial species are cultivated and where trees are selectively cut and burned to replicate healthy forest succession.

As if musical chords, these activities are all interconnected, each of them with its own time and space that respect the flooding cycles with their seasons of high and low waters. These seasons set the pace. Floods comes first, replenishing the ecosystem of the plains. The fish reproduce, eat and fertilize the soil. Then comes fishing in low waters after the fish are abundant. Lastly, when water is scarcer, but the soil has been enriched in organic matter, farming and hunting are the main ways to produce food.
