The effects on Amazon floodplains of the dynamics between the water and land

Abstract Waters and lands in the Amazon, especially near the Solimões/Amazonas Rivers, are very dynamic, recreating the landscapes along the rivers' paths. The waters transport and deposit eroded materials, causing changes in the lifestyles of the meadow's residents. In addition to this, there are the recent climatic changes caused by the El Niño phenomenon, intensifying the meadows' transformations. This research explored the quantitative and qualitative values of knowledge of local people in order to understand the environment in which they live. With an understanding of the islands' environmental system and the perceptions of seventeen female farmers of the amazon meadow, coupled with appropriate theory and methods, it was possible to explore and execute this research. Valha-me-Deus and Chaves, both in the county of Jurupis, PA, were the islands chosen for the study. The goal of the study was to characterize the dynamics of the waters and lands of the Amazon River together with the re-creation of the river islands and the effects of climate change over the floodplains. The data show meaningful changes in the studied environmental systems, resulting in irreversible losses in the cultivation of food crops such as papaya, cocoa, manioc and bananas, especially after the intense river flooding of 2009.
