The Role and Importance of Evaluating Ecosystem Economic Services Specially Wetlands In Supporting Natural Resources and to Increase Society Welfare

Most ecosystem services are public goods or assets that cannot or should not be considered private. In principle monetary value of these services are estimated by benefits for society and if the services are lost, profits will be lost accordingly. Among different ecosystems, wetlands are the most productive ecosystems on the planet and this is not only associated with high biodiversity, they also play an important role in maintaining the balance of life on Earth and make it possible.

In this study, the steps of determining information selection criteria in the economic valuation of wetland ecosystem services include the following processes: 1) Providing first-hand information from the studied areas; 2) Monetary valuation for ecosystem services, so that they can be attached to a particular biome at a specific time; 3) providing information about the surface of the regions (about which ecosystem services can be converted to monetary value per hectare; 4) providing information about the evaluation method used; 5) providing information about the study site, area and study scale (native, local, Regional, continental and global).

wetlands are now one of the ecosystems that were influenced by increasing human activities, changes in land use of large parts of the surrounding beaches and urban pollution discharges and also agricultural activities. Continued overuse of ecosystems has increased cost of living and future generations will suffer from poverty. After the change in land use, many of the foreign positive effects of ecosystems are destroyed or severely reduced and improvement of public goods and services is possible through ecosystems that are in serious situation and this needs a firm decision to improve them for conserving environmental diversity and sustainable management of ecosystems.

Economic valuation of ecosystem services in the best way is a supplement for traditional decision-making framework in which positive and negative external effects or losing of many environmental goods and services that are not known is significant. Monetary value can help us by determining external effects and increasing our insight of the role and economic importance of nature through qualitative and quantitative measurements. The economic valuation of ecosystem services is therefore important for society and can provide us strong and reliable communication tool for informing a better and more balanced decision-making in the field of trade and related land resources.
