Regional economic impact assessment (REIA) and social impact assessment (SIA) are methodologically close, since REIA provides predictions of change in employment both directly and indirectly resulting from a project, thereby giving some indication of future population changes, derived demand for social services and infrastructure, and the likely regional social mix. There are, however, a number of theoretical difficulties with conventional REIAs. As extrapolations they normally avoid discussion of processes of structural change, which could result in substantial changes within the time horizon of a project. Another issue is the justification for including secondary project impacts in assessing a project's worth....

Synopsis: Beneficial arthropods, including native bees, predators, and parasitoids, provide valuable ecosystem services worth $8 billion to US agriculture each year. These arthropod-mediated ecosystem services (AMES) include crop pollination and pest control, which help to maintain agricultural productivity and reduce the need for pesticide inputs. Maximizing survival and reproduction of beneficial arthropods requires provision of pollen and nectar resources that are often scarce in modern agricultural landscapes. Increasingly, native plants are being evaluated for this purpose. Native plants can outperform recommended non-natives and also provide local adaptation, habitat permanency, and support of native biodiversity....

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system were developed to define an updated hydrogeologic framework as part of the U.S. Geological Survey Groundwater Resources Program. This feature class contains a gridded surface depicting the top of the Lower Floridan aquifer in feet relative to NGVD29.
Recently, an active debate has emerged around greenhouse gas emissions due to indirect land use change (iLUC) of expanding agricultural areas dedicated to biofuel production. In this paper we provide a detailed analysis of the iLUC effect, and further address the issues of deforestation, irrigation water use, and crop price increases due to expanding biofuel acreage. We use GLOBIOM – an economic partial equilibrium model of the global forest, agriculture, and biomass sectors with a bottom-up representation of agricultural and forestry management practices. The results indicate that second generation biofuel production fed by wood from sustainably managed existing forests would lead to a negative iLUC factor, meaning...
Description of Work U.S. Geological Survey (USGS) will use remote sensing data to establish a baseline understanding of current distributions of invasive wetland plants and then forecast potential invasion corridors. Alterations to the Great Lakes shoreline or water-level patterns associated with global climate change could have significant impacts on the extent and composition of coastal habitat. Low lake levels can expose fertile wetland bottomlands to invasive species such as common reed ( Phragmites). Goals & Objectives Goals: Identify current Phragmites distribution in the Great Lakes coastal zone, detect potential areas vulnerable to invasion due to influences such as altered water levels, nutrient and...

Synopsis: Agronomic intensification has transformed many agricultural landscapes into expansive monocultures with little natural habitat. A pervasive concern is that such landscape simplification results in an increase in insect pest pressure, and thus an increased need for insecticides. We tested this hypothesis across a range of cropping systems in the Midwestern United States, using remotely sensed land cover data, data from a national census of farm management practices, and data from a regional crop pest monitoring network. We found that, independent of several other factors, the proportion of harvested cropland treated with insecticides increased with the proportion and patch size of cropland and decreased...

Synopsis: This study investigated the magnitude of change in landscape structure resulting from road and logging since the onset of timber harvesting in 1950. Overall, roads were found to have had a greater impact on landscape structure than logging. A three-fold increase in road density between 1950 and 1993 accounted for most of the changes in landscape configuration including mean patch size, edge density, and core area. Change in landscape structure varied as a function of landscape extent. At a large scale of 228,000 ha, change in landscape change over time was trivial, suggesting that the landscape is capable of incorporating disturbances with minimal impact. At intermediate scales of 1000-10,000 ha, change...

Conclusions:Results indicate that breeding bird species richness patterns significantly increased with fragment size. Area-sensitive species required patches of suitable habitat at least 5-55 ha in size. Edge and vegetation-restricted species were more affected by overall habitat loss of habitat than reductions in average patch size.Thresholds/Learnings:Area-sensitive species required patches of suitable habitat at least 5-55 ha in size, and regularly avoided smaller grassland fragments even when they were composed of suitable habitat

This paper summarizes the main results of a study on the costs of abatement of CO2 emissions in Brazil. It discusses three possible futures for the long run (2010 and 2025) activity of the Brazilian economy and -- with the help of a linear programming model for Brazil's energy sector -- three scenarios for energy production and use. One of these scenarios illustrates the possibility of halving future carbon emissions originating from energy generation and consumption, with relatively small increases in energy associated costs and investments. This abatement scenario would require, on the supply side of the Brazilian energy balance, increased amounts of hydropower, ethanol and bagasse from sugarcane, plus wood and...

A 20-year comprehensive water clarity database assembled from Landsat imagery, primarily Thematic Mapper and Enhanced Thematic Mapper Plus, for Minnesota lakes larger than 8 ha in surface area contains data on more than 10,500 lakes at five-year intervals over the period 1985–2005. The reliability of the data was evaluated by examining the precision of repeated measurements on individual lakes within short time periods using data from adjacent overlapping Landsat paths and by comparing water clarity computed from Landsat data to field-collected Secchi depth data. The agreement between satellite data and field measurements of Secchi depth within Landsat paths was strong (average R2 of 0.83 and range 0.71–0.96). Relationships...

Conclusions: Increasing seismic line density from 0 to 8 km/km2 resulted in a 38% decline and an 82% decline in bird abundance when individuals used lines as territory boundaries or avoided edges by 50 m, respectively. When tested with ovenbirds, male ovenbirds showed a distinct use of one side of the seismic line, suggesting lines acted as territory boundaries. Ovenbirds declined with seismic line density when a threshold seismic line density of 8.5 km/km2 was reached. Above the threshold, Ovenbirds declined 19% for each 1 km/km2 increase in seismic line density. Thresholds/Learnings: Synopsis: In the boreal plains of Alberta, Canada, energy sector exploration has resulted in extensive dissection of the landscape...

The study examined the effects of forest harvest practices that approximate natural disturbance processes to evaluate whether these practices help conserve biodiversity. Past research has shown that management practices that mimic natural disturbance events such as forest fires is a successful habitat conservation strategy, particularly for boreal forest bird communities. The study investigated how bird communities differed between postharvest and postfire stands in the mid-boreal region of Alberta. The research found that the most significant difference between postfire and postharvest landscapes is the amount and orientation of residual live and dead trees. Postfire stands consist largely of standing dead trees...
