Pastures and sown fields
T7.2 Sown Pastures and Fields
Layer representing the extension in the Amazon of the functional ecosystem of grasslands and sown fields.
These are anthropogenic ecosystems, managed primarily for agricultural production, with a predominance of introduced herbaceous species and human practices such as crop rotation or intensive soil management. These anthropogenic landscapes are designed to maximize production, often at the expense of biodiversity and natural ecological resilience. In areas of increased activity, soil compaction and degradation of soil ecological capacity increase. Very serious situations of residue, fertilizer and pesticide concentrations can occur, compromising soil and water quality.
This layer represents one of the functional ecosystems in the Amazon region, designated as part of modified biomes or anthropogenic biomes. They present (occurrence) of type 2 representing different variants of this ecosystem modified or altered by human activities. This ecosystem is described in detail in (DESCRIP), which includes key characteristics such as vegetation structure, biodiversity, level of human influence and prevailing environmental conditions. The ecological realm or realm to which the ecosystem belongs is specified in the (Realm) field: its associated biome is indicated in (Biome) by categorizing it according to broad climatic and geographic characteristics. The ecosystem's functional group is described in (FunctionGr), and is uniquely identified by a standard code (code, e.g., "T1.1 Tropical-Subtropical lowland rainforests"). Finally, the (URL) field is a link to the Global Ecosystems website, where additional information such as maps and detailed documentation of the corresponding functional ecosystem can be accessed.
Functional ecosystems, developed as part of the Global Ecosystem Typology framework published by IUCN in 2020, represent a global approach to classifying ecosystems according to their key ecological processes, functions and dynamics. This typology is crucial for understanding how ecosystems support biodiversity and ecosystem services. In addition, its data are fundamental for promoting sustainable development and guiding the management of natural areas at the local level, providing a scientific basis for conservation, ecological restoration and land-use planning that benefits both human communities and biodiversity.
