Relationships between species composition and its environmental determinants are a basic objective of ecology. Such relationships are scale dependent, and predictors of species composition typically include variables such as climate, topographic, historical legacies, land uses, human population levels, and random processes. Our objective was to quantify the effect of environmental determinants ...
16 The goal of this work is to inter-compare four global land surface emissivity products over 17 various land-cover conditions to assess their consistency. The intercompared retrieved land 18 emissivity products were generated over five-year period (2003-2007) using observations from 19 the Advanced Microwave Scanning Radiometer Earth Observing System (AMSR-E), Special 20 Sensor Microwave Imag...
Over the last decade, following the doi moi reforms, the Vietnamese government has formally recognised the household as the basic unit of production and allocated land use rights to households. Under the 1993 Land Law these rights can be transferred, exchanged, leased, inherited, and mortgaged. A ‘land market’ is emerging in Vietnam but is still constrained for various reasons. Additionally, la...
Understanding settler colonialism as an ongoing structure rather than a past historical event serves as the basis for an historically grounded and inclusive analysis of U.S. race and gender formation. The settler goal of seizing and establishing property rights over land and resources required the removal of indigenes, which was accomplished by various forms of direct and indirect violence, inc...
Understanding patterns, processes, and consequences of land-cover change requires close linkages among various ecological, socioeconomic, demographic, and behavioral data. In this chapter, we present an interdisciplinary study of human impacts on land cover and panda habitat in Wolong Nature Reserve (China). Wolong is one of the largest reserves (200,000 ha) designated for giant panda conservat...
There is a growing need for consistent and up to date land cover data at various scales by regional, national and European authorities. Main drivers are recent or upcoming European directives and initiatives, which contain increasingly spatially differentiated monitoring and reporting obligations in agriculture, environmental protection, water management, soil protection or spatial planning. De...
mixed land use includes various land uses which are adjacent to each other and linked together to accommodate either horizontal or vertical segments adjacent land and within a building to coexistence. recent urban planning theories, emphasizing on several principles that make the mix use development is one of these principles. mixed land use effects on travel demands and urban transportation ef...
Current developments in the field of land use modelling point towards greater level of spatial and thematic resolution and the possibility to model large geographical extents. Improvements are taking place as computational capabilities increase and socioeconomic and environmental data are produced with sufficient detail. Integrated approaches to land use modelling rely on the development of int...
Gully erosion is the most important water erosion which causes land degradation and imbalance in lands. Land degradation, broken ecological balance of landscapes and sensitive condition of biological resources are among reasons of gully erosion study. This study performed with the goal of determining the topographical threshold of gully erosion and expansion and also predicting sensitive areas ...
The process of infiltration is one of the most important components of the hydrological cycle. On the other hand, the direct measurement of infiltration process is difficult, time spending and expensive. Infiltration models play a main role in managing water resources. Therefore, different types of models with various degrees of complexity were developed to reach this aim. So, this research ca...
