road network (rn) can affect patterns and distribution of land uses and covers. road network expansion has both direct and indirect impacts on land uses and covers changes. agricultural land conversions (alcs) are especially known as one of the main important types of land use changes. the purpose of this paper, in addition to estimation of the direct impact of rn expansion on alcs, is to evalu...

We developed an irrigation mapping methodology that relies on remotely sensed inputs from MODerate Resolution Imaging Spectroradiometer (MODIS) instrument, globally extensive ancillary sources of gridded climate and agricultural data and on an advanced image classification algorithm. In the first step, we used climate-based indices of surface moisture status and a map of cultivated lands to pro...

Drought is a natural phenomenon that causes lot of damages annually in various sectors, including agriculture and resources. The aim this study to evaluate the influence meteorological drought index on vegetation index. For purpose, standard precipitation (SPI) as calculated using data 28 stations located area Lorestane province, Iran, during years 1987–2017. Then, condition (VCI) computed norm...

In farming conditions with good water or irrigation, planting of varieties belonging to the intensive type gives results. The importance increases even more when using accelerated technology in wheat cultivation. potential yield and product quality a variety depends on genetic characteristics growing agrotechnics [7-8, 11]. High productivity is achieved cultivation conditions, including agrotec...

BACKGROUND This study was conducted to estimate the level of heavy metals accumulate in vegetables irrigated with contaminated water compared with those irrigated with fresh water in Hamadan, west of Iran in 2012. METHODS Sixty samples of different vegetables i.e., parsley, tarragon, sweat basil and leek irrigated with contaminated water and thirty six samples from three different adjacent ar...
