There are presented results of the economic valuation of the habitat service and biodiversity losses caused by the Dniester hydropower complex functioning. Habitat services were evaluated for two bird species (glossy ibis, Plegadis falcinellus, and yellow heron, Ardeola ralloides) and fish spawning grounds. The evaluation of biodiversity services was carried out for the Ramsar sites “Lower Dniester” and “Unguri - Holosnita”. The current cost of discussed losses in the Moldavian part of the Dniester basin is about USD 6.7-7.1 million.

Early life stages of fish spawned on the Norwegian continental shelf have long been suggested to depend on eggs and nauplii from the crustacean zooplankton Calanus finmarchicus for survival. Calanus finmarchicus overwinters in the deep basins of the Norwegian Sea, and gravid females must be advected onto the shelf prior to spawning if eggs and nauplii larvae are to serve as food for fish larvae. In this study, cross-shelf advection of C. finmarchicus is simulated over 52 years (1960–2011) using a numerical ocean model coupled with an individual-based model. The results suggest that cross-shelf transport of C. finmarchicus is surprisingly stable across years and that transport is particularly concentrated immediately upstream of the two major spawning areas for the Northeast Arctic cod (Gadus morhua) and the Norwegian spring-spawning herring (Clupea harengus), namely Lofoten and Møre, respectively. Two large topographical features, the Træna Trough and the Norwegian Trench, appear to be funnelling C. finmarchicus onto the shelf in these two areas. This could suggest that the fish spawning grounds outside Møre and Lofoten are, in part, maintained owing to stable interannual food supply in spring.

Abstract The Latuppa Nature Tourism Area of Palopo City is an area designated as a tourist destination for the community, both local and from outside the Palopo City area. Various tourist objects are available in this area, both naturally formed such as the Latuppa River flow with several tourist spots, as well as natural panoramas in the form of forests and other landscapes, which are spread in 3 villages, namely Latuppa Village, Murante Village and Kambo Village, Mungkajang District, Kota Palopo. The existence of this area provides added value to the regional income of Palopo City. However, this added value has not been measured quantitatively so that research efforts are needed on the economic assessment of this natural tourist area. The methodology used in this research is quantitative descriptive by observing every tourist spot in the Latuppa natural tourism area, including the Water Boom Hotel Agrowisata, Kambo Highland Inn, Babak Waterfall, and the Natural Baths of the Jodoh River. The factors that influence the number of visits to the Latuppa Nature Tourism location are travel costs, and socio-economic factors of the community. The calculation of the economic value for the natural tourism area uses the Travel Cost Method (TCM), from the analysis results obtained the Economic Value of the Latuppa Nature Tourism Area is Rp. 311,574,900. It is hoped that the results of this study can be a reference for the local government of Palopo City in the context of developing and preserving the Latuppa nature tourism area.

In the last decades, an increased interest has been expressed by researchers from worldwide towards studies about economic valuation of protected areas given that environmental public goods are not always traded on a market. Economists have struggled with this subject for decades and have developed several methods to estimate the economic values of these goods, known as non-market valuation methods. This paper reviews and presents a brief analysis of the most popular techniques as applied to natural areas, which are compared after grouping the research steps in five common steps for a consistent comparative analysis. Moreover, renowned studies conducted worldwide are revealed for each of the methods. A special interest has been noticed towards the estimation of welfare measures, such as Willingness To Pay (WTP) and consumer surplus, and towards differentiating user groups, as well as introducing several factors that may influence the decision to visit the natural areas. The case of Romanian national and natural parks is discussed in detail with the purpose to emphasize the need to continue the research in the field. The unique character of each of the studied parks, marked by geographic and cultural aspects, was confirmed through statistic analyses and thus welfare measures were determined for each park separately. The performed analyses proved that the methods have applicability in Romania as well.

AbstractThe effects of climate change are increasingly more visible on natural ecosystems. Being mountain forest ecosystems among the most vulnerable and the most affected, they appear to be, at the same time, the most suitable for the assessment of climate change effects on ecosystem services. Assuming this, we review the literature on the economic assessment of climate change impacts on European mountain forests. Initially, the trends in the provision of mountain forest ecosystem services are discussed. We, then, considered the effects on forest structure and tree physiology, these two being strictly associated with the capability of the ecosystem to provide ecosystem services. The results have been grouped into a table that displays the trend, the quality and the quantity of the information found. Subsequently, the main methods that can be employed to assess the economic value of the different ecosystem services have been described. For each method, some implementation examples have been introduced to better understand its functioning. Concluding, the main gaps still existing in literature concerning the effects of climate change on ecosystem services provided by mountain forests have been highlighted. Finally, some more considerations about the existing methods for the economic valuation of ecosystem services have been done.

Human health and wellbeing are intrinsically connected to our seas and oceans through a complex relationship comprising both positive and negative influences. Although significant public health impacts result from this relationship, the economic implications are rarely analysed. We reviewed the literature to assess current knowledge on the economic valuation and impacts of ocean and human health interactions in a European context. Quantitative analyses on the economic impacts of varying ocean-health interactions were limited. Common challenges to economic assessment included the difficulty in obtaining estimates for indirect healthcare costs, under-reporting of illness and the lack of standardization of surveillance data on illnesses, when available. It was also evident that non-market values, such as health promotion and psychological benefits are underrepresented in economic assessments, most likely because of the lack of standardized valuation methods for such non-market values. We provide recommendations to improve knowledge of ocean and human health linkages and progress future assessment of its economic implications in Europe.

The cement industry constitutes a major source of air pollution and its environmental impacts have historically raised considerable public concern. This paper presents a health-based economic assessment of reducing particulate and sulfate emissions from a cement industrial complex. The economic valuation of the potential decrease in mortality and morbidity rates due to emissions reduction was conducted using a human capital approach and a cost of illness approach, respectively.

Numerical modeling of braided channels showed no significant differences in the number of cross-sectional branches between different water periods in the middle reaches of the Yarlung Tsangpo River. During most of the year (wet, normal and dry periods), flow velocities in the higher-branching (HB) channels were significantly lower than in the other two branching categories, while the overall distribution of depth in the higher-branching channels maintained a high degree of consistency with the moderate-branching channels (MB), which partly explains why the HB channels are important habitats for fish spawning, nursery and baiting (lower flow velocity distribution with a wider range of depth). Based on the examination of the water surface width, the water surface width may not be a limiting factor for fish habitat within braided rivers. Simulation of the hydrodynamic parameters of the fish-spawning grounds revealed that the average cross-sectional flow velocity and water depth fluctuated the least at different flows during the fish-spawning period for the HB channels. By counting the hydraulic parameters of the spawning grounds during the spawning period, it can be seen that the most preferred flow velocity for fish in the braided river in the study section was 0.1-0.4 m/s, and the water depth was 0-1.2 m. This article analyses the characteristics of the hydraulic parameters of the braided river and provides theoretical support for the restoration of fish habitats in braided rivers.
