Rural populations are undergoing rapid changes in both their livelihoods and land uses, with associated impacts on ecosystems, global biogeochemistry, and climate change. A primary challenge is, thus, to explain these shifts in terms of the actors and processes operating within a variety of land systems in order to understand how land users might respond locally to future changes in broader-sca...
A proactive sampling strategy was designed and implemented in 2000 to document changes in streams whose catchment land uses were predicted to change over the next two decades due to increased building density. Diatoms, macroinvertebrates, fishes, suspended sediment, dissolved solids, and bed composition were measured at two reference sites and six sites where a socioeconomic model suggested new...
in the present research land use changes modeling in the urmia city is considered in order to detect changes in agricultural lands. in this regard, landsat satellite images were used and then the object base processing satellite images was performed by applying the process segmentation and in the next stage, the optimization of scale segmentation and image analysis to its constituent elements, ...
land use management policy and method are two important factors in usage of land by human. in this regard, evaluation of environmental capability would serve as a valuable basis for the best use practice of soil and water resources in addition to the reduction in environment consequences of the projects. in the correct study, the environmental capability of birjand plain, located in the south k...
China is a populous agricultural country, the arable land is the most basic resources which is needed for agricultural production, the quality of arable land has a direct impact on the entire agricultural production and development ,so to carry out the Evaluation of Farmland is a very important foundation work which is advantage to know china’s arable land resources and to improve the efficienc...
Increases in populations and in particular in developing countries are placing increased pressure on both natural and agricultural resources. In many cases, especially in semi-arid regions, the pressures are compounded by restricted agricultural lands. Reliable and relevant land evaluation is a requirement for land use policy and decision making to support sustainable rural development. Land ev...
The area of agricultural land withdrawn for non-agricultural purposes is gradually increasing worldwide, which mainly due to the conflicting interests entities that are interested in use this natural resource. Between 2009 and 2020, agricultural more than 16,000 ha was Slovakia purposes. It can be considered a threat purpose withdrawal mostly industrial subsequently housing, from it possibl...
Mashhad City, according to the latest official statistics of the country is the second populated city after Tehran and is the biggest metropolis in the east of Iran. Considering the rapid growth of the population over the last three decades, the city’s development area has been extended, significantly. This significant expansion has impacted natural lands on suburb and even some parts e.g. rang...
This study investigates how property taxes a¤ect development timing. A theoretical framework motivates an empirical model that explores how land use change decisions are made over time. A survival model using plot level data is estimated to show how di¤erent factors in‡uence the timing of development of individual parcels. The results suggest that higher taxes slow development, as expected. Wit...
In this study, we analyze the effect of property taxes on changes between agricultural, forestry, Conservation Reserve Program, and developed land uses in Louisiana. We estimate a random parameters logit model of land-use conversion from the National Resources Inventory plot data. Our results indicate that land-use changes are inelastic with respect to property taxes. Simulation shows that curr...
