Simulação de perdas de solo em função de cenários de adequação ambiental em microbacias agrícolas
(2013-06-01)
In São Paulo state, deforestation and agriculture activities are increasing soil losses processes, especially in areas of susceptible soils where soil conservation practices are not adopted. Environmental adequacy at ...
Production of clean water in agriculture headwater catchments: A model based on the payment for environmental services
(2021-09-01)
This study aimed to present a payment for ecosystem services model that promotes a symbiotic coexistence between agriculture and clean water production. The model favors application to headwater catchments where clean water ...
Influence of environmental features at multiple scales and spatial structure on stream fish communities in a tropical agricultural region
(Taylor & Francis Inc, 2017-01-01)
Land cover change for agricultural expansion exerts strong pressures on tropical streams. We examined the relative contributions of catchment land cover, local environmental features, and spatial patterns on stream fish ...
Influence of landscape properties on stream water quality in agricultural catchments in Southeastern Brazil
(Edp Sciences S A, 2015-01-01)
Changes in land cover, especially the replacement of forest by agricultural activities affect the hydrological processes of river catchments, resulting in physical and chemical compositional changes of water draining from ...
Estimation using 18O of the water residence time in small watersheds
(1992-01-01)
From the 18O hydrograph separation method, it was found that groundwater contribution is the principal component of the total discharge produced by these two catchment areas. The weighted mean of the 18O concentration in ...
The effects of land use at different spatial scales on instream features in agricultural streams
(2017-07-01)
The conversion of forests into agriculture has been identified as a key process for stream homogenization. However, the effects of this conversion can be scale-dependent. In this context, our aim was to identify the influence ...
A regression model of stream water quality based on interactions between landscape composition and riparian buffer width in small catchments
(2019-01-01)
Riparian vegetation represents a protective barrier between human activities installed in catchments and capable of generating and exporting large amounts of contaminants, and stream water that is expected to keep quality ...
Using indicators of deforestation and land-use dynamics to support conservation strategies: A case study of central Rondonia, Brazil
(ELSEVIER SCIENCE BV, 2009)
In Rondonia State, Brazil, settlement processes have cleared 68,000 km 2 of tropical forests since the 1970s. The intensity of deforestation has differed by region depending on driving factors like roads and economic ...
