Soil carbon can be sequestered through different land management options depending on the soil carbon status at the beginning of a management period. This initial status results from a given soil management history in a given soil climate regime. Similarly, the prediction of future carbon storage depends on the time sequence of future soil management. Unfortunately, the number of possible manag...

abstract- inadequate water supply is the major problem for agriculture in arid and semi-arid regions. thus, effective management should be considered for water resources planning. in this research, a model was provided which is able to estimate optimal land and water allocation in the doroodzan irrigation network. optimal water management model was used at farm level to evaluate different defic...

over the past few decades, several models such as the lp model have been used for managing watersheds and determining optimal cultivation pattern for agricultural planning. management and planning methods are the most important applied tools of management science for optimal allocating resources in order to gain the most profits in the different fields including natural resources, water resourc...

extended abstract 1.introduction today the role and the importance of open and green spaces are significantly increasing in the environment and the quality of building complex. therefore, open and green spaces are considered as intrinsic, parts of land use planning decision in most countries. the gardens in the city of jahrom are the indexes of iranian thought and creativity and also the climat...

This paper describes a class of spatial planning problems in which di,erent land uses have to be allocated across a geographical region, subject to a variety of constraints and con.icting management objectives. A goal programming/reference point approach to the problem is formulated, which leads however to a di/cult nonlinear combinatorial optimization problem. A special purpose genetic algorit...
