چکیده
R apid population growth, coupled with economic expansion, is increasing the demands on land not only for agriculture but also for housing, infrastructure, recreation, and industry. Many of the agricultural regions in South and Southeast Asia characterized by intensive rice-or rice-wheat-based agroecosystems provide striking examples of conflicts in agricultural land-use objectives. The need for crop diversification to increase labor productivity and farmers' income and prevent migration to rapidly expanding megacities often directly conflicts with the necessary increase in staple food production and maintenance or improvement of the quality of the natural resource base (soil, water, air). Identification and implementation of production systems and technologies that make optimum use of external inputs and natural resources and avoid natural resource degradation, and policy measures supporting their adoption for sustainable agricultural development, would be the keys to resolving such conflicts. In this context, one of the research challenges is how to develop effective tools for land-use planning and resource analysis that can make the issues transparent in the search for feasible solutions. was launched as a methodology development project in support of the IRRI-coordinated Ecoregional Initiative for the Humid and Subhumid Tropics of Asia [EcoR(I)]. The project was expected to contribute to the design, exploration , and evaluation of land-use options at higher integration levels. Specifically, its objectives were to develop methodologies and tools for exploratory land-use analysis and to evaluate these for generating options for policy

A Hybrid Method Based on Fuzzy AHP and VIKOR for the Discrete Time-Cost-Quality Trade-off Problem
Time, cost and quality are considered as the main components in managing each project. Previous researches have mainly focused on the time-cost trade-off problems. Recently quality is considered as the most important factor in project�s success, which is influenced by time acceleration that is the less time is spent the more success is gained. In time-cost-quality trade-off problems, each act...

The interbasin water transfer is a remedy to mitigate the negative issues of water shortage in arid and semi-arid regions. In a water transfer project the receiving basin always benefits while, the sending basin may suffer. In this study, the project of interbasin water transfer from Dez water resources system in south-west of Iran to the central part of the contrary is investigated during...
