Tropical forests suffer the loss of millions of hectares every year due to land use and land cover change for agricultural production, resource exploitation and settlement development, contributing to global warming and altering the environmental conditions of the territory, as in the city of Iquitos in the Peruvian Amazon, where it is necessary to know how these impacts affect its population, activities and ecosystems. The objective of the study was to analyse the effects of urban expansion and global warming on the climate of the city of Iquitos, as well as its variation in relation to the climate of the towns of Pebas and Trompeteros, in the Peruvian Amazonian peneplain in the period 1984-2022, for which meteorological data from the study area was processed, maps of ecosystems and satellite images were processed to determine levels of vegetation vigour by calculating the normalised di...
