In an integrated dynamic general equilibrium model of the economy and the ecosystem humans and other species compete for land and prey biomass. Each submodel exhibits a price-driven competitive allocation mechanism, and the endogenously determined habitat is either openly accessible or privately owned. In both scenarios specific corrective taxes or subsidies are needed to internalize ecosystem ...

This paper draws upon a detailed longitudinal survey of households living on agricultural plots in the northern three provinces of the Ecuadorian Amazon, the principal region of colonization by migrants in Ecuador since the 1970s. Following the discovery of petroleum in 1967 near what has subsequently come to be the provincial capital and largest Amazonian city of Lago Agrio, oil companies buil...

“Eco-urbanization” emphasizes the importance of the ecological and environmental aspects of urbanization, which is to approach a balanced and healthy ecosystem through paying attention to the ecological intercorrelation of many factors. This involves balancing the stocks and utilization of multi-resources and balancing the efficiency and equality of multi-resources allocation to improve the qua...

CSIRO Division of Plant Industry, P.O. Box 1600, Canberra City, A.C.T. 2601, Australia. Abstract: Southeastern and southwestern Australia have quasiand classical-Mediterranean climates respectively. Vegetation varies widely from forests to woodlands to shrublands. Attitudes to landscape have been important in allocating land use in these areas with a general contrast between what is "practical"...

Space allocation of urban facilities is a critical field of decision making in urban planning. Supposing that Geographic Information (GI) provide us with more objective parameters for space allocation, Geographic Information Systems (GIS) is used by urban planners. But usage of GIS in urban planning is limited to simple analyses believing that complex spatial analyzes complicate the currently e...

Top-down land change models use computer simulation to allocate demands for change over the spatial region under study. This paper presents a metric to estimate the goodness of fit of land change models. It focuses only on changed areas, preventing inflated goodness of fit values due to large fractions of the landscape remaining unchanged. We use the proposed metric to evaluate land change mode...

In this paper we are concerned with modelling techniques for evaluating development and conservation opportunities when dealing with investment decisions involving environmental resources management. In this context, highly characterized by both environmental and economic uncertainty, we emphasize the importance of capturing the flexibility of different investment strategies. In particular, we ...

This paper compares the performance of a two-sided combinatorial call market, direct negotiation, and double auction for consolidating fragmented land. Experimental results suggest direct negotiation produces higher efficiencies than other mechanisms. The combinatorial call market tends to alleviate the exposure problem, and performs well when 1) swapping is easily agreeable, and 2) the number ...

This paper presents a fuzzy goal programming (FGP) approach for optimal allocation of land under cultivation and proposes an annual agricultural plan for different crops. In the model formulation, goals such as crop production, net profit, water and labor requirements, and machine utilization are modeled as fuzzy. A tolerance based FGP technique is used to quantify fuzziness of different goals ...

Lake areas in Chinese urban fringes are under increasing pressure of urbanization. Consequently, the conflict between rapid urban sprawl and he maintenance of water bodies in such areas urgently needs to be addressed. An integrated GIS-based analysis system (IGAS) for supporting and-use management of lake areas in urban fringes was developed in this paper. The IGAS consists of modules of land-u...
