Estimation of the value of forest ecosystem services to develop conservational strategy management (strengths, weaknesses, opportunities and threats)

Abstract

Jahanifar K., Amirnejad H., Abedi Z., Vafaeinejad A. (2017): Estimation of the value of forest ecosystem services to develop conservational strategy management (strengths, weaknesses, opportunities and threats). J. For. Sci., 63: 300-312.Forests ecosystems provide several undisputable benefits which policy-makers blink since these values do not record in conventional markets or are difficult to measure. This paper indicates that the annual value of the ecosystem services such as water conservation, soil protection, carbon fixation, nutrient cycling, water purification, air pollution absorption and recreation provided by forests is not only worth millions of dollars, but also in per hectare terms much more than hitherto known. After estimating the value of ecosystem services, results are available to policy-makers and experts at a brainstorming and by using SWOT, conservational strategies for long-term management based on strengths, weaknesses, opportunities and threats were developed. Ecosystem services value for the Mazandaran Forest Reserve ranged from 14.2 to 14.8 million USD or about 6,676.9-6,785.6 USD·ha -1 . Given these results, raising the society awareness of the negative impact of forest land use changes based on the functional value were proposed as conservational strategies to prevent the forest land use change. If these are accounted for, then governments and societies faced with the development versus conservation dilemma can create more understanding decisions and policies that will assist to conserve forests and the ecosystem services they provide, and thereby promulgate human well-being and sustainable development.

“…The value of water conservation for each of pine forest and oak forest was 45.95US$/ha/year. This value is lower than that of 64.12 and 146.79 US$/ha/year in Iran and China respectively as reported by (Komeil, J., 2017) and (Xue and Tisdell, 2001) respectively. This could be attributed to amount of precipitation which is greater in the study area of these two nations which facilitate obtaining denser forest.…”

Economic Assessment of Selected Regulatory Ecosystem Services (RES) in the Elgeyo and Nyambene Watersheds Ecosystems in Kenya

“…The amount of purified water was based on the estimated annual precipitation kept by the two ecosystems. The unit cost of the purification function was based on the unit cost of constructing and maintaining a backup facility (municipal water treatment plant) (Jahanifar et al, 2017). This was based on the assumption that the destruction of the forest ecosystem would cause water quality degradation, which would require the construction of a municipal wastewater treatment plant to replace the ecosystem function.…”

“…Despite the high economic value of these goods, they are not sufficiently considered by economic policies and regulations; this indicates that there is not a sufficient investment in its protection and management. To guarantee the provision of ecosystem services, it is necessary to support and maintain the functions of ecosystems and protect biodiversity, so that these must be managed sustainably [73,74].…”
