“…Several field and semifield studies in which fate and behaviour of PPP active substances were tightly traced over a season or a year at very high spatial resolution have been reviewed. These studies provide vertical concentration gradients of the compounds in soil horizons of one or few centimetre thickness (Fent et al., ; Anderson et al., ; Poßberg et al., ; Toschki et al., , ; Egerer et al., ). The distributions in the soil profile of substances with different physicochemical properties and from different experiments are depicted by way of example in Figure .…”

Following a request from EFSA, the Panel on Plant Protection Products and their Residues developed an opinion on the science behind the risk assessment of plant protection products for in-soil organisms. The current risk assessment scheme is reviewed, taking into account new regulatory frameworks and scientific developments. Proposals are made for specific protection goals for in-soil organisms being key drivers for relevant ecosystem services in agricultural landscapes such as nutrient cycling, soil structure, pest control and biodiversity. Considering the time-scales and biological processes related to the dispersal of the majority of in-soil organisms compared to terrestrial non-target arthropods living above soil, the Panel proposes that in-soil environmental risk assessments are made at in-and off-field scale considering field boundary levels. A new testing strategy which takes into account the relevant exposure routes for in-soil organisms and the potential direct and indirect effects is proposed. In order to address species recovery and long-term impacts of PPPs, the use of population models is also proposed.

“…There are, however, significant questions concerning the depth to which SOC and other soil components should be measured and modelled (Anderson et al, 2010;Grüneburg et al, 2010;Malmoud et al, 2009) and how different soil properties such as texture, bulk density and rock content (BlancoCanqui et al, 2009;Hassink, 1997;McLauchlan, 2006;Ruehlmann and Körschens, 2009;Six et al, 2002) and climate (Chatskikh et al, 2009;Grüneburg et al, 2010;Li et al, 2006;Van Oost et al, 2005;Wang et al, 2004), affect SOC distribution down the soil profile. In Australia the recommendation is to measure SOC to 30 cm depth (McKenzie et al, 2000).…”

“…This statement become even more relevant if taking account the fact that decision makers are frequently asked to define the risk associated with biological conservation. The determination of the potential ecological risk areas or, in this case, border ecological risk, has important implications for direct management and investments related to conservation biology (ANDERSON et al, 2010). It is very important to reserve efforts and financial resource to priority areas, such as high ecological risk ones.…”

In recent decades the United Nations published that the scarcity of fresh water available for consumption could be a barrier to development of all countries. This reality becomes even more alarming considering the increased in population density, especially in megacities where water resources are still suffering because of punctual pollution sources. In underdeveloped countries this scenario is even more critical. Lack of financial resources for sanitation planning and implementation causes faster degradation of water bodies, bringing an imminent risk to these region populationsdue todisease spread, for example. In this way, its necessaryto reformulate the water resources monitoring projects, especially those placed in urban areas, used for large metropolitan areas supply, such as the Billings-Guarapiranga Complex, located in São Paulo. In these regions, rivers and reservoirs end up losing the characteristic of public assets and become abiotic elements in the landscape without cultural value or as a basic need for life. However, unfortunately the Brazilian current public management system is in crisis and so onweneed to innovate the way the monitoring projects is performed in order to reduce field work costs to collect samples and analyze them. In this context, the use of GIS tools, combined with the products obtained by remote sensors can effectively contribute to the reverse the current level freshwater ecosystems degradation. The idea is to create processes not only to assess the reservoirs quality, but also helpsto create and update the current master plans and ecological-economic zoning. This paper presents a set of tools to assist the water resources management, both in assessing of reservoirs trophic status, as in the analysis of catchment basin border ecological risk. It is possible to have a very concrete idea of the ecological risk associated with water resources through the phytoplankton biomass modeling by concentration of chlorophyll-A, the extraction of drainage networks and the analysis of land use in the catchment basin can. The results obtained here compared to others, points out the potential of the proposed methodologies. Furthermore, processing of Landsat 5/TM series helped in identifying chlorophyll-A concentration spatial dynamics, allowing the identification persistent contamination areas in 2003 and 2010. Finally, we believed the reader should feel encouraged to develop new models and update the current ones. The set of proposed tools can effectively contribute to the water resourcesmanagement.
