Historical records of socio-environmental impacts related to large-scale iron ore development in Brazil are driving different planning approaches in the burgeoning iron mining and smelting complex of Corumbá, located at the border of the Pantanal ecosystem in the Brazilian state of Mato Grosso do Sul. Among the most relevant efforts are two strategic environmental assessments (SEA): one was led by a mining company and the other by a civil society committee. This paper assesses to what extent these SEAs can contribute to the mitigation of negative socio-environmental impacts of the Corumbá Complex. It also evaluates if the SEA methodologies meet a number of SEA Performance Criteria. The analyses, which were based on literature reviews and content analysis of the SEA documents, reveal that the two SEAs represent an important effort to incorporate environmental variables into more strategic levels of the Pantanal region's planning. Nonetheless, both SEAs have serious limitations, given that they are not formally nested in governmental policies, plans and programmes.

Nanotechnology is a newly emerging field, posing substantial impacts on society, economy, and the environment. In recent years, the development of nanotechnology has led to the design and large-scale production of many new materials and devices with a vast range of applications. However, along with the benefits, the use of nanomaterials raises many questions and generates concerns due to the possible health-risks and environmental impacts. This chapter provides an overview of the Quantitative Structure-Activity Relationships (QSAR) studies performed so far towards predicting nanoparticles' environmental toxicity. Recent progresses on the application of these modeling studies are additionally pointed out. Special emphasis is given to the setup of a QSAR perturbation-based model for the assessment of ecotoxic effects of nanoparticles in diverse conditions. Finally, ongoing challenges that may lead to new and exciting directions for QSAR modeling are discussed.

Agricultural Activity

<p>Crop production is applied on about half of Hungary’s land area, which amounts to approximately 4.5 million hectares. The agricultural activity has significant environmental impacts.</p><p>Our work aims the time series investigation of the impacts of large-scale agricultural cultivation<strong> </strong>on environment and primarily on climate change in<strong> </strong>the test area by applying environmental life cycle assessment (LCA) method.</p><p>The investigated area of Lajta Project can be found in the triangle formed by the settlements Mosonszolnok, Jánossomorja and Várbalog, in the north-western corner of Hungary, in Győr-Moson-Sopron county. The area has intense agri-environment characteristics, almost entirely lacking of grasslands and meadows.</p><p>We were looking for the answer to the question “To what extent does agricultural activity on this area impact the environment and how can it contribute to climate change during a given period?” The selection of the plants included in the analysis was justified by their significant growing area. We analysed the cultivation data of 5 crops: canola, winter barley, winter wheat, green maize and maize. Material flows of arable crop production technologies were defined in time series by the agricultural parcel register data. These covered the size of the area actually cultivated, the operational processes, records on seeds, fertilizer and pesticide use and harvest data by parcels. The examined environmental inventory database contained also the fuel consumption and lubricating oil usage of machine operations, and the water usage of chemical utilization.</p><p>In the life cycle modelling of cultivation, we examined 13 years of maize, 20 years of green maize, 20 years of winter barley, 18 years of winter wheat and 15 years of canola data calculated on 1 ha unit using GaBi life cycle analysis software.</p><p>In addition, we also calculated by an average cultivation model for all cultivated plants with reference data to 1 ha and 1 year period.</p><p>We applied methods and models in our life cycle impact assessment. According to the values of the impact categories, we set up the following increasing environmental ranking of plant cultivation: (1) canola has minimum environmental impacts followed by (2) green maize and (3) maize with slightly higher values, (4) winter barley has 6 times higher values preceded by (5) winter wheat with a slight difference. The previous environmental ranking of the specific cultivated plants’ contribution was also confirmed as regards the overall environmental impact: canola (1.0%) – green maize (4.9%) – maize (7.1%) – winter barley (43.1%) – winter wheat (44.0%).</p><p>Environmental impact category indicator results cumulated to total cultivation periods and total crop growing areas (quantitative approach) display the specific environmental footprints by crops. Increasing environmental ranking of environmental impacts resulted from cultivating the sample area is the following: (1) canola – (2) maize – (3) green maize – (4) winter barley – (5) winter wheat. The slight difference resulted in the rankings in quantitative approach according to the rankings of territorial approach on the investigated area is due to the diversity of cultivation time factor and the crop-growing parameter of the specific crops.</p><p>Acknowledgement: Our research was supported by the „Lajta-Project”.</p>

In this paper, we aim to shed light on the geographies that led both to the selection of Lodge Hill for the construction of a large-scale housing development and to the subsequent attempt to use biodiversity offsetting to compensate for its environmental impacts. We draw on extensive fieldwork from 2012 to 2016, and diverge from previous studies on offsetting by focusing less on issues related to metrics and governance and shifting our analytic attention to the economic and urban geographies surrounding the Lodge Hill case. We argue that this approach can offer not only an empirically grounded account of why offsetting is being selected to address the impacts of specific urban development projects, but also an in-depth understanding of the factors that determine offsetting’s actual implementation on the ground. Viewing the Lodge Hill case through the frame of urbanization allows us to better grasp the how, why and when particular alliances of actors contest and/or support the implementation of biodiversity offsetting. Our analytical lens also helps exposing the fragility of neoliberal natures and the roles inter-capitalist competition and species biology and ecology can play on the success or failure of neoliberal policies.

Salvage Harvesting

The increasing prevalence and/or increasing intensity of large-scale natural disturbance events in forests means that post-disturbance salvage logging is becoming more widespread. Salvage logging can have a wide range of environmental impacts, but some of these are not well known or not well understood by policy makers and natural resource managers. Some of these impacts are briefly summarized in this paper. Improved long-term forest planning needs to be embraced that takes into account the not only the environmental but also the social and environmental impacts of salvage harvesting. Past mistakes and future opportunities associated with salvage harvesting are illustrated by a case study from the Lower Cotter Catchment in south-eastern Australia. Key words: salvage harvesting, natural disturbance, environmental impacts, ecologically sustainable forestry, forest planning, long-term forest sustainability
