The ASTER sensor onboard NASA’s Earth observing satellite Terra is an optical remote sensor comprised of 14 spectral bands ranging from the visible to thermal infrared region. With its multispectral bands the sensor bears the potential to provide data for both a detailed land use classification of heterogeneously vegetated areas. This study evaluates the potential of ASTER data for land use cla...
There is a global increase in the recognition of environmental, social and economic values of native vegetation, particularly in terms of both sustainability of agricultural production and maintenance of natural resources. The rapid growth of the human population in Sudan (2.6 % per year) stimulated the evolution of mechanized agriculture in the Gedarif Area from 500 ha in the 1940s to about 2....
Australia's "Direct Action" climate change policy relies on purchasing greenhouse gas abatement from projects undertaking approved abatement activities. Management of soil organic carbon (SOC) in agricultural soils is an approved activity, based on the expectation that land use change can deliver significant changes in SOC. However, there are concerns that climate, topography and soil texture w...
abstract- agricultural extension agents should provide dry land producers with appropriate education to make them more interested in learning about water use optimization. therefore, it is recommended to accompany education with art. in this regard, a study, using the randomized experimental research design, was carried out among dry land grape producers in herayjan village, southwest iran, usi...
Land is one of the prime natural resources. A city grows not only by population but also by changes in spatial dimensions. Urban population growth and urban sprawl induced land use changes and land transformation. The land transformation is a natural process and cannot be stopped but it can be regulated. Many geographical changes at the urban periphery are associated with the transfer of land f...
Agricultural productivity is determined and limited in general by a combination of the natural environment and technical measures. If non-capital intensive management is assumed, the natural potential and constraints are of specific importance for the agricultural land use and its productivity. In this context, the Potsdam Institute for Climate Impact Research (PIK) in cooperation with the Max ...
The earth's surface, due to its natural conditions and its structure is always changing and reshaping. One of the created deformations is the land subsidence. This is the most dangerous events which can be seen in most urban areas especially in the agricultural plains today. This study aims at zoning land subsidence and recognition of geometrical factors in southwest of Tehran. To estimate and ...
