the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
The impact of growth management policy through zoning ordinances on land-use and -cover change is a topic of increasing interest, especially with regard to urban sprawl and forest and agricultural land preservation. As urban and residential land use is quickly replacing extractive land use in southern Indiana, implementation of growth management policy has become a topic of great debate. This a...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
Alternative land use zoning scenarios provide guidance for sustainable land use controls. This study focused on an ecologically vulnerable catchment on the Loess Plateau in China, proposed a novel land use zoning model, and generated alternative zoning solutions to satisfy the various requirements of land use stakeholders and managers. This model combined multiple zoning objectives, i.e., maxim...
Oregon's land-use planning program is often cited as an exemplary approach to forest and farmland conservation, but analyses of its effectiveness are limited. This article examines Oregon's land-use planning program using detailed spatial data describing building densities in western Oregon. An empirical model describes changes in building densities on forest and agricultural lands from 1974 to...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
Zoning strategic agricultural land for protection has become important in reducing agricultural land loss in rapidly growing areas. In this paper, a constrained CA model based on the integration of remote sensing, GIs, and cellular automata (CA) techniques was developed to overcome the limitations of the existing methods commonly used b y planners in zoning land for agricultural protection. Rem...
This paper examines the effects of environmental zoning policies on lakefront land development, sorting, and economic welfare in a model where agents are heterogeneous in preferences and income. Agents consume lakefront amenities that are endogenous to development and the sorting process yields lakes which differ by amenities and frontage prices. Our findings include the following: i) lakes bec...
prediction of the agricultural developmental problems has ever been one of the goals of proper agricultural development, to gain more productions from the minimum resources. the goal of this research is zoning prone area of olive cultivation with two methods: gis and genetic algorithm. also the results have been compared with the current olive cultivation areas in lorestan province and the resu...
