[1] The utility of a thermal image sharpening algorithm (TsHARP) in providing fine resolution land surface temperature data to a Two-Source-Model for mapping evapotranspiration (ET) was examined over two agricultural regions in the U.S. One site is in a rainfed corn and soybean production region in central Iowa. The other lies within the Texas High Plains, an irrigated agricultural area. It is ...

This paper examines and evaluates the integrated use of satellite remote sensing and meteorological data for estimating crop water requirements over agricultural areas of Cyprus. Intended purpose of this project is to estimate evapotranspiration using modeling techniques, satellite and meteorological data for monitoring irrigation demand. ETc was calculated with the FAO Penman-Monteith method b...

Exochus atlanticus sp. n., Melo & Penteado-Dias, and Trieces broadi sp. n., Melo & Penteado-Dias, are described and illustrated in Brazilian fauna. The genus Exochus and the species E. ablatus, E. izbus, T. azipas, T. riodinis, T. wardae, T. upermia and T. wascia, are recorded for the first time from Brazil. Diagnosis and distribution information for each species are provided.

[1] Agricultural water use accounts for around 70% of the total water that is withdrawn from surface water and groundwater. We use a new, gridded, global-scale water balance model to estimate interannual variability in global irrigation water demand arising from climate data sets and uncertainties arising from agricultural and climate data sets. We used contemporary maps of irrigation and crop ...

urban expansion and agriculture intensification are relevant drivers in land degradation (ld)processes in europe due to net loss of land, soil sealing, landscape fragmentation and other negative effects on the environment. this paper explores changes (or “trajectories” of change) in land use and cover (lulc) and their relationship with the consumption of soils in emilia-romagna (northern italy)...

This article presents a series of multidimensional analysis methods on agricultural factors at county level, performing subsequently a comparison between the results obtained in 2004 and, respectively, in 2008. By applying factor analysis, principal components analysis and hierarchical classes analysis, this article will seek to highlight the main variables that influence the agricultural produ...

110 Journal of Plant Registrations, Vol 2, No. 2, May 2008 ‘Alice’ (Reg. No. CV-1023, PI 644223) hard white winter wheat (Triticum aestivum L.) was developed by the South Dakota Agricultural Experiment Station and coreleased by the South Dakota and Nebraska Agricultural Experiment Stations in August 2006. In addition to researchers at South Dakota State University, researchers at the University...
