Gridded fields of changes in discharge due to historical deforestation and conversion to agriculture from Douglas et al. (2005). This historical scenario compared discharge (Q) generated from pre-industrial land cover with discharge derived from contemporary landcover. Change in Q = difference between river discharge (Q) generated from pre-industrial land cover (based on WWF Terrestrial Ecoregions of the World (Olson et al., 2001) with river discharge derived from contemporary landcover. Historical and contemporary Q was estimated from flow routed RO generated by the UNH Water Systems Analysis Group Water Balance Model (WBM) at a 30' (lat x long) spatial resolution (Fekete et al. 2002).

Artificial drainage has major ecosystem impacts through the development of extensive ditch networks that reduce storage and induce large-scale vegetation changes. This has been a widespread practice of water table management for agriculture in Eastern North Carolina. However, these features are challenging to identify because the structure has been determined by non-natural factors. A dataset of open ditches was processed by calculating terrain (also, positive) openness – a value based on a line-of-sight approach to measure the surrounding eight zenith angles as viewed above the landscape surface.

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. This spatial dataset consists of 219 1-kilometer (km) resolution grids depicting estimated agricultural use of 219 pesticides in 1997 for the conterminous United States. Each grid cell value in the national grids of this dataset is the estimated total kilograms (kg) of a pesticide applied to row crops, small grain crops and fallow land, pasture and hay crops, and orchard and vineyard crops within the 1- by 1-km area. Nonagricultural...
This spatial dataset consists of 199 1-kilometer (km) resolution grids depicting estimated agricultural use of 199 pesticides in 1992 for the conterminous United States. Each grid cell value in the national grids of this dataset is the estimated total kilograms (kg) of a pesticide applied to row crops, small grain crops and fallow land, pasture and hay crops, and orchard and vineyard crops within the 1- by 1-km area. Nonagricultural uses of pesticides are not included in this dataset. Of the 199 pesticides represented in the grids, 92 are herbicides, 58 are insecticides, and 32 are fungicides. The remaining 17 grids are composed of the category "other pesticides", which consists of fumigants, growth regulators,...

This dataset was combined by CBI from 219 1-kilometer (km) resolution grids depicting estimated agricultural use of 219 pesticides in 1997 for the conterminous United States produced by the USGS. CBI selected those pesticides that had nonzero values within this ecoregion. CBI created an additional attribute "PEST_SUM" that represents a value weighted sum across all pesticides, produced by summing together the proportion of the value for a particular pesticide for a given pixel to the total amount of that pesticide observed within this ecoregion. This sum approaches a greater number where more of the pesticides are applied at higher quantities relative within this ecoregion. This attribute has not been approved by...

In this project on future sustainable transport alternatives a two-step search process has been followed. First an analysis of critical success and failure factors of new technological options in passenger transport is made. These factors are found in the spatial, institutional, economic and social/psychological environment of the transport system. Next, systematically structured and expert based scenarios are con- structed in order to achieve a sustainable transport system in the year 2030 in which possible, expected and desired developments in the distinct fields are analyzed. Finally some policy conclusions are drawn.

Improved understanding of the innovative pathways of renewable energy technologies is vital if we are to make the transition to a low carbon economy. This study presents new evidence on innovation and industry dynamics in concentrating solar power (CSP) technologies. Though CSP is undergoing a renaissance, existing innovation studies have explored innovative activity in solar technologies in general, ignoring the major differences between solar photovoltaic and CSP technologies. This study, based on patent data, examines the level and dynamics of innovative activity in CSP between 1978 and 2004. Our unique contribution, based on engineering expertise and detailed datawork, is a classification system mapping CSP...

Gridded fields of the relative change in river discharge representing the ratio of the change in river discharge (delta Q) due to hypothetical future forest conversion to agriculture divided by contemporary Q from Douglas et al. (2005). This dataset compares river discharge (Q) generated from the contemporary landcover with river discharge generated from a hypothetical, 'worst-case' future deforestation scenario. Relative change in Q = change in river discharge (delta Q) due to hypothetical future forest conversion to agriculture divided by river discharge derived from contemporary landcover. Delta Q = difference between river discharge (Q) generated from a hypothetical future forest conversion scenario with river...

This project helps the Central Valley Joint Venture (CVJV) track gains and losses of key bird and waterfowl habitats at a landscape scale. This will allow the CVJV to effectively monitor and evaluate habitats essential to conservation planning for wildlife species. This work is important for identifying, assembling, and analyzing data for key habitats of concern and will provide a foundation for future monitoring.

This data set contains county-level estimates of nitrogen and phosphorus from fertilizer, for both farm and nonfarm uses, for the conterminous United States, for 1987 through 2012. State-level farm and nonfarm nitrogen and phosphorus were derived from the Association of American Plant Food Control Officials (AAPFCO) commercial fertilizer sales data. State estimates were then allocated to the county-level using fertilizer expenditure from the Census of Agriculture as county weights for farm fertilizer, and effective population density as county weights for nonfarm fertilizer. Data computations for 2007 - 2012 estimates are results of methods applied directly from Gronberg and Spahr, 2012. Data for 1987 - 2006 are...
