The Pantanal wetland is a mosaic of landscapes that brings together rich biodiversity with the valuable activities of fishing, tourism and ranching. Human occupation and land use in the headwaters have intensified the rate of channel avulsions in the lower reaches of the largest megafan on the Taquari River. This study evaluates the long-term changes of landscapes in the active depositional lobe of the Taquari megafan from the perspective of local communities of pantaneiros. Maps derived from multiple decades of multispectral Landsat data have proven useful for studying land cover changes through the relationship between dry (terrestrial vegetation and soil/dry pastures) and humid landscapes (open waters, aquatic macrophytes and wet soils), as well as through Sankey diagrams and spatiotemporal mapping with Boolean operations according to the rate of dryland recovery. We found that dryland recovery associated with an older and smaller avulsion (known as Zé da Costa) is analogous to that of a most recent and much larger avulsion (known as Caronal), which is still ongoing and has greater importance due to the scale of the impacts. Land value and fish capture depreciate as the partial Caronal avulsion still evolves, increasing the likelihood of environmental conflicts. While pantaneiros no longer profit from ecosystem services of provision (e.g., livestock or fishing), dryland recovery may deliver quantifiable ecosystem services of regulation. The strengthening of partnerships among stakeholders and the implementation of environmental compensation mechanisms are central for the best management of the Pantanal's megafans that ensure quality of life for all pantaneiros.

Resumo: O objetivo desta pesquisa foi avaliar o grau de desuniformidade no desempenho de um sistema de irrigação por sulco do Perímetro Irrigado de São Gonçalo, Sousa, PB, decorrente das variações espacial e temporal em parâmemtros de campo e operacionais. Para se quantificar essas variações, foram realizadas avaliações de campo em seis sulcos, escolhidos de forma a abranger ao máximo as variações no sentido transversal da área irrigada. Observou-se variações espaciais máximas, ao longo da estação de cultivo, iguais a 33,0, 162,0 e 140,5%, respectivamente, na eficiência de aplicação, na taxa de escoamento e na taxa de percolação; enquanto espacialmente, as variações temporais máximas para esses parâmemtros foram de 26,3, 78,4 e 233,3%. Abstract: The purpose of this research was to evaluate the degree of non-uniformity of furrow irrigation system performance generated by spatial and temporal variations in field and operational parameters. At each irrigation event along the crop season, field evaluations were performed in six furrows chosen in such way to comprise most of the spatial variations. Maximum spatial variations in the application efficiency, tailwater ration and deep percolation ration were equal to 33.0, 162.0 and 140.5%. Spatially, for tho same parametrs the maximum temporal variations were 26.3, 78.4 and 233.3%. |
