Putting a Value on Nature's Free Services

To give value to the free services of nature is trying to weigh and evaluate the externalities the environment faces, unlike other problems that we have read up to now. In general, both arguments present the same view: environmental services should be evaluated. However, these discussions differ in the sense that one of them suggests that these services are possible, others mean that it is difficult to measure this value . The first parameter is used to measure the value and the second parameter is used to measure the value.

Natural ecosystems carry out basic life support services on which human civilization depends. However, many people think that nature provides these services for free, so they are little or not worth it at all. These services may not spend as much as $ 1 to the world's population, but daily decisions in most cases will have some impact on the size and quality of the ecosystem services provided. We (in this case we are a country) have not paid their expenses, but we do not pay for wastewater treatment facilities, temporary suspension of greenhouse gases, increased disease, a decrease in soil fertility, Pay a huge fee for loss. Contributing to our basic happiness Therefore, what we do not want to worry about nutrition regulation, harmful pollution, poor soil productivity, climate disaster or illness (physical or mental) loss It is not to deal with it.

Review of human welfare factors emphasizing the contribution of ecosystem services

Ecosystem services refers to processes provided by nature to support human life. Pollination, waste disintegration, water purification, renewal of soil fertility, reduction of floods, etc. Ecological processes tend to be overlooked and often are not considered part of the economy until they do not function. When it assigns economic value to these services it will be very high. For example, insect pollinators help to produce many commercially important fruits such as almonds, melons, blueberries and apples. Worldwide economic value of insect pollination service is equivalent to $ 217 billion annually

There is a way to give water price by assigning economic price to water. Principle 4 of Dublin deals with the economic value of water. Providing economic value to nature and its services is very controversial, as critics believe that it underestimates biodiversity that is not being traded. However, by giving the economic value of water, the natural benefits are related to people's interests (Berdik, 2014). If people give the economic value of water, this water can be effectively distributed to the extent that biodiversity is not affected. In the case of hydropower dams, water is not evaluated effectively, so people give energy value through water. Effectively monitor water and services when pricing water
