Land-use change around protected areas can reduce their effective size and limit their ability to conserve biodiversity because land-use change alters ecological processes and the ability of organisms to move freely among protected areas. The goal of our analysis was to inform conservation planning efforts for a nationwide network of protected lands by predicting future land use change. We eval...

the aim of this study was to assess the conversion of forest to vineyard on different physical pools of organic matter in zrebar lake watershed. soil samples were collected from the two major land use types including forest and vineyard land at 0-30; 30-60, and 60-90-cm depths. in each land use, different soc fractions were measured. according to the results of size fractionation of organic car...

The advantage of ENVISAT ASAR over its predecessors, namely ERS-1 and ERS-2, as a land observation tool resides in its multiple polarization and multi-look angle capabilities. As a radar sensor the ASAR backscattering coefficient is sensitive to the moisture content of the scattering media and its geometrical properties (i.e. size, shape, roughness, and orientation). From the quantitative analy...

This study analyzed the determinants of the productivity of smallholder arable crop farmers with a particular focus on land fragmentation using the Simpson Index as measures of land fragmentation in Imo state of Nigeria. Data collected by using structured questionnaire and interview schedules were analyzed using simple descriptive statistics; Simpson index and regression analysis. Results showe...

This paper deals with the optical recognition of text data in documents such as engineering drawings, land-use and land-register maps, and utility maps. The automatic computer acquisition of these documents is performed through the basic steps of vectorization of the line-structure and recognition of the text data interspersed in the document. The latter data are usually handwritten by professi...

An intensive survey was conducted on HNZ land, a subsidiary of Hunt Inc., which owns the mineral rights to land located adjacent to the Petrified Forest National Park, Arizona, United States. The purpose of the survey was to log the position and characteristics of petrified wood to better protect the fossils from thieves and to assess the value of Hunt lands. A monetary value was assigned to ea...

We performed a laboratory common-environment study to determine the genetic and environmental sources of variation in growth rates of the sagebrush lizard (Sceloporus graciosus). Hatchling lizards were reared from gravid females collected from three study populations along an elevational gradient in southern Utah, USA. Hatchlings were fed ad libidum and were maintained on a 14:10 light:dark cyc...

1. introduction the phenomenon of land consolidation has been the concern of economists, geographers, soil scientists, anthropologists, and politician in the last decades. it has achieved little success for agricultural development in iran. most of iranian land consolidation schemes ignore to meet sustainability criteria as a critical phase in the planning process. therefore, they have caused m...
