The optimization of land-use structure is the core of optimizing the allocation of land resources, including the optimization of quantity and space. However, traditional methods such as multi-objective programming model, gray system, landscape ecology are very difficult to make the space structure and the quantity structure unified effectively. To avoid the deficiencies mentioned above, this pa...

This paper aims at evaluating the impacts of climate change on land use patterns in Brazil. To this purpose, we specify and estimate an econometric land use model to assess how climate variables affect land allocation decisions according to three types of use: cropland, pasture and forestland. Based on the econometric model estimates, we then simulate how farmers will adapt their land use choic...

This study analyzes the optimal allocation of the world’s land resources over the course of the next century within a dynamic forwardlooking framework, which brings together distinct strands of economic, agronomic, and biophysical literature and incorporates key drivers affecting global land-use. We show that, while some deforestation is optimal in the near term, the desirability of further def...

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 describes multiple criteria models that can be used to assess land condition in general, and military training areas in particular. Three measures of land condition are used, namely: 1) erosion status, which is estimated based on the Revised Universal Soil Loss Equation (RUSLE), 2) percent vegetative cover, and 3) range condition. In addition, the paper also describes site-specific t...

We propose a framework with endogenous allocation of land between agricultural production, sustainable forest management, and unsustainable forest exploitation in the form of illegal logging to explore deforestation and agricultural and timber supplies when property rights are insecure. Uncertainty over property rights arises through risk of confiscation on sustainably-managed forest land, and ...

People find themselves confronted with ever starker tradeoffs in the allocation of resources to competing uses and users. At the local level, for instance, allocation of land or water to agricultural, industrial, municipal, recreational, and conservation activities often involves a zero sum game. This is apparent in the widespread loss of water and land from native habitat to farms and increasi...

in recent years, due to absence of integrated watershed management in most regions, natural resources have witnessed numerous damages with severe floods as one of its consequences which further leads to economic, social and environmental damages. presently, there is no optimal utilization of land in most watersheds hence no optimal model matching with facilities and objectives is used in the wa...

A ca. 1980 national-scale land-cover classification based on aerial photo interpretation was combined with 2000 AVHRR satellite imagery to derive land cover and land-cover change information for forest, urban, and agriculture categories over a seven-state region in the U.S. To derive useful land-cover change data using a heterogeneous dataset and to validate our results, we a) stratified the cl...
