Parthenium hysterophorus, an invasive alien weed, is spreading rapidly across various land uses in Nepal. To understand how Parthenium is spreading across land uses at local scale, occurrence of this weed was recorded and its’ coverage in percent estimated along trails and road network at every 100 meter distance in Kirtipur Municipality of Kathmandu valley. In addition, vegetation sampling was...

The study assessed soil erosion features in hilly agricultural watersheds in central Sichuan Province, China. Relationships among area percentages of land covers, soil erosion modulus, soil loss rate, and area percentage of erosion in the watersheds were examined by multivariate regression analysis. The first two regression models were constructed with area percentages of land covers as indepen...

nowadays, population growth and on the other hand resources limitations astonish authorities. population changes cause variation in economic activities and land use changes. as a whole, overusing, improper land use and human disturbances over natural resources make environmental imbalances worse. in recent decades, we have seen land use changes in taleghan basin. land use changes were produced ...

The use of satellite technology by military planners has a relatively long history as a tool of warfare, but little research has used satellite technology to study the effects of war. This research addresses this gap by applying satellite remote sensing imagery to study the effects of war on land-use/land-cover change in northeast Bosnia. Though the most severe war impacts are visible at local ...

Secondary forest succession on abandoned agricultural land has played a significant role in land cover changes in Europe over the past several decades. However, it is difficult to quantify over large areas. In this paper, we present a conceptual framework for mapping forest succession patterns using vegetation structure information derived from LiDAR data supported by national topographic vecto...

the kind of land use and intensity of its change is considered as important desertification indices in different models. land use change is one of the main anthropogenic factors in the desertification. the current research was carried out around imam khomeini airport, with an area of 32000 km2, in order to evaluate mentioned area's land use changes effects during 1955-2003 on desertification. t...

in agroforestry landscapes, land use, and the associated management practices exert strong impacts upon soil organic carbon stocks. data on the soil organic carbon were collected for different land-use types within a small watershed, el salado, located in lanjarón (se spain). eight land-use types namely: farmland planted in olive, almond, and cereals; forest with pinus halepensis mill. and pinu...

Distributed erosion models are potential tools for identifying soil sediment sources and guiding efficient Soil and Water Conservation (SWC) planning. However, the uncertainty of model predictions has yet to be resolved. Splash erosion is one of the most important mechanisms in soil loss. In this study, monthly splash detachment rates were predicted using the Morgan, Morgan and Finney (MMF) emp...

Human-driven land-use changes increasingly threaten biodiversity. In agricultural ecosystems, abandonment of former farmlands constitutes a major land-use shift. We examined the relationships between areas in which agriculture has been abandoned and the distribution records of threatened plant species across Japan. We selected 23 plant species that are currently identified as threatened but wer...

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....
