The Amazon Basin has the greatest diversity of freshwater worldwide with fishing being the main source for income and subsistence for riverine and forest dwelling communities. Overexploitation of this ecosystem poses risks for food security of the communities that depend on it while simultaneously decreasing ecological ecosystem functioning and household income. When addressing these threats and strengthening fishing practices, in-depth involvement of local fishing communities is needed.
In the Colombian Amazon region, the organisation of artisanal fishermen TIKA belongs to the seven communities of the aquatic system of the Yahuarcaca lakes. They carry out community and biological monitoring. Community monitoring meaning visiting these seven indigenous fishermen communities in order to explore their communities’ situation, current issues, practices and values. Biological monitoring refers to biological fish identification, fish measurements and ecosystem dynamics. Monitoring is also realized in the local wetlands, where the so-called ´Pepeaderos´ are to be found – tree species which provide habitats and food sources for many of the local fish species and thus also food security to the Amazonian communities.
