Agricultural expansion and intensification are main drivers of land-use change in Brazil. Soybean is the major crop under expansion in the area. Soybean production involves large amounts of water and fertiliser that act as sources of contamination with potentially negative impacts on adjacent water bodies. These impacts might be intensified by projected climate change in tropical areas. A Water Footprint Assessment (WFA) serves as a tool to assess environmental impacts of water and fertiliser use. The aim of this study was to understand potential impacts on environmental sustainability of agricultural intensification close to a protected forest area of the Amazon under climate change. We carried out a WFA to calculate the water footprint (WF) related to soybean production, Glycine max, to understand the sustainability of the WF in the Tapajós river basin, a region in the Brazilian Amazon with large expansion and intensification of soybean. Based on global datasets, environmental hotspots ? potentially unsustainable WF areas ? were identified and spatially plotted in both baseline scenario (2010) and projection into 2050 through the use of a land-use change scenario that includes climate change effects. Results show green and grey WF values in 2050 increased by 304% and 268%, respectively. More than one-third of the watersheds doubled their grey WF in 2050. Soybean production in 2010 lies within sustainability limits. However, current soybean expansion and intensification trends lead to large impacts in relation to water pollution and water use, affecting protected areas. Areas not impacted in terms of water pollution dropped by 20.6% in 2050 for the whole catchment, while unsustainability increased 8.1%. Management practices such as water consumption regulations to stimulate efficient water use, reduction of crop water use and evapotranspiration, and optimal fertiliser application control could be key factors in achieving sustainability within a river basin.

This comparative study on environment-tree growth relationships of the high quality native tree species Swietenia macrophylla King (mogno) and Carapa guianensis Aubl. (andiroba) is part of the development of sustainable landuse systems on "terra firme" sites of the Central Amazon within the Brazilian-German research cooperation SHIFT. As to get information on the site demands and the growth characteristics of plantation systems of mogno and andiroba: (1) monoculture system, and (2) an enrichment system (both stablished in 1992 at the experimental site of the Embrapa Amazonia Ocidental, Manaus-AM). The water balance of the plantations was quantified by evaporation and transpiration/xylem flux measurements as well as the calculation of the water run-through in the soil (Cl-method). The K supply of the trees was investigated by quantified input (precipitation, throughfall, stemflow, litterfall) and output (K uptake of the vegetation, leaching out of the soil). The cambial growth dynamics of the trees was dated in one-month-intervals by the pinning method - period April 1995 until December 1996). A reduced soil water content with a suction force in the upper soil layer (depth 20cm) of 500 hPa to 900 hPa was found from August until November in both plantation systems. High evaporation and water run-through caused short periods with low soil water contents (300 hPa to 400 hPa) even during the wet season in monoculture systems. A cambial dormancy or a reduced rate of cambial cell divisions of mogno was found during the drier season from August to December whereas the cambial growth dynamics of andiroba was not correlated with the annual course of the soil water content. K cycling was improved in the enrichment system compared to the monoculture system, whereas the K supply of the soil was reduced. The reduced xylem production of mogno in the enrichment system compared to the monoculture system was correlated with the low K content of the soil in this system. From these results i was concluded that andiroba is more competitive for sustainable growth on this site than mogno.
